welcome to the section 4 contiguous wet cleaning or altering and ship-to-ship process when he was beaten omission from a senior mechanical engineer I was Precision Engineering which is based in Eindhoven in the Netherlands why
do indeed Kulturklass King In wrote raunchy tissue processors particles are a major cause of the writers no contamination cannot always prevent so therefore it is necessary to clean the particles in the production process conventional methods of cleaning contacts claiming for example by means of sticking rose 11 this has certain risks particles can be imprinted in the fall ownership that you're cleaning or sense players that only she can be damaged therefore we designed a new good cleaning principle which is narrowing gap cleaning let
me explain the targets that we have set for this research project 1st of all the goal of the research was to develop a cleaning tool for removal of particles from moving for using principles the targets and we have said is to be equal or better than current contract cleaning methods and to be better than content clinging to no
mercy for months apart because it means that we want to achieve the cleaning efficiency of rides 90 cent and for all the particles between 1 140 electoral interests we really like to achieve a cleaning efficiency of better than 50 per cent of all the particles larger than 20 micrometers cleaning efficiency of large and a 90 cent let me explain
how to narrow the gap between the principal works you never
get the man is built of a sandwich structure of foreign media and tables 1 1st media Canter was placed on top of the others on the bottom and the substrate for ownership is being guided imagery and into the gap between the substrate and each of the parchment and tables as small as 18 to 20 50 mark from the porous media and
tables combined to ask shit or Web handling and she directly it virtually no the same the structure of shooter when handling an airflow is guided through the porous media which creates a stiff layer of air above stove substrate the cruise it the at symbol I the 2 of the extracts vacuum all to inserts an airflow this means that you can create stream of air over the structure and the stream of air is used to clean the substance using his
methods particles are removed from the substrate and not out of the area where they conclude on the media so there out and collectors in the area near the what are the advantages
of area because the concept is designed to keep the air flow in a contained in an environment so me and had outside of that and now we're clean and will not be influenced by the the airflow inside the mayor of the air consumption is low because the high-speed Ackerman created because the gap is so small
furthermore epa's media manage themselves have very low consumption by nature as the SPD so high we can penetrated the boundary layer that exists on top of the the surface Of the substance How
do we set this small gaps in their please we have designed set up with which you can use micrometres crews to exactly adjusts the gap in between to Bosnia and tables To start with new gage rocks To get a defiant initial debt depending on the full thickness you need to adjust the adapt to the desired high with effect which can done by using my descriptors we have desire to
set up for America playing and once and for shooter should and wants to look for too Clinton 1st started to talk about so for ship-to-ship pleaded with this so we have designed and overlying cameras which was developed to measure particles a small 125 migrants the
way we determined cleaning efficiency all are never get cleaner is as follows 1st we get a substrate and last played in this example With particles and deposited on in this country dust particles which have been collectors by exposing the last date to open or can be an aluminum particles were still particles on upon before playing we inspect last played by placing it on the camera system next to the plate clean and after cleaning we reposition only camera system on the exact same location we do this so we can get a one-to-one comparisons of each location before and after training some details
about the cameras the camera uses bright light illumination like most cameras and has an optical wrote resolution of 125 recommendations this is achieved by microscope objective which is mounted to the camera camera resolution is 0 . 3 by 0 . 3 Microni dissent as better than the optical resolution so the camera is not limited the field of view is
0 . 6 1 0 . 6 9 mm which is fairly small Due to the very high up on a resolution that will achieve the repeatability of placing the sheets before and after cleaning is 10 micrometres really and step ability of dissent that we have developed is also only 10 were likely this way we can
very accurately replaced the glass plates after clinging on the exact same location as we have placed it before and we can compare that to conditions With
this summer we are able to detect very small particles in in the air shows zoomed in section Of the image that comes from the camera and the conceded particles as small as 10 commuters or 5 for micrometres undetected in particles of 1 where commuters can be found but these are not have winger from press to be detected by an imaging software the particles that we have used our reference particles which have defined the size of 10 4 1 1 1 like which you can see in the picture after wrapping the
images with the camera the images need to be converted In imaging software to be able to come apart many methods exist for converting images and we have tested and verified many of these elements to be able to achieve the the highest quality of counting particles was the highest reliability factor in counting particles in images is noise image for example if lighting is an even more if bottles are overlapping and images with too much noise must be rejected from the process we have designed an an algorithm that automatically can reject too noisy images that removes the factor of personal judgment whether managers to noisy and not and increases the repentant of the process moreover it increases the speed because manually checking 70 images which are taken before and send images which had taken off the plane takes a lot of time so this but legions of vastly improved the speed of testing so we can easily take 70 or multiple times images to do data analysis of this way we have achieved a very sorrow it was a way of comparing 1 image before clinging to a 1 image after cleaning with very high quality is slices
shows 2 examples With before Clinton and after cleaning In the right image from all the season before cleaning situation and then everything next to it shows the digital image which has been created by the computer the computer Council particles and determines the size of each part of the picture below you see that most of the particles have been removed from press some small particles remain and computer image which is next to it you can actually matched those particles to the particles that were there in the image before the slide shows another example is see that it is name the very small particles that remain on the last plates and all the particles have been removed as
government set of tests that we have performed using a ship-to-ship Clinton we have used standard-size it's 6 white 6 inch glass plates and also we have used that place on the same side this plates were artificially community contaminated with environmental there's still aluminum particles and also with spray Polish during Silicon I cited molybdenum particles which had control particle size from 1 4 down like we had tried different throughput speeds from 1 to 100 million meters per 2nd and we have also varied began to see if there was any influence from 85 micrometres to 213 but I assure
you that made the results of this research with ship-to-ship could the cleaning efficiency over last place To be able to enter these results should be aware that each graph represents 17 locations before and 70 locations after which have been compared to each other and which have been checked for noisy images moreover for each type of of experiment that we didn't like aluminum and glass plates Newman about players still on the glass plates preamble multiple rounds to make sure that we got consistent vision
this slide shows the major results follow a set of experiments that I just mentioned it would look under wraps conceived free brass dust particles unless aluminum particles in the middle still particles right the top brass showing the actual amount of particles there were counted greens before the cleaning and red which is much smaller is optically the drop below show the cleaning efficiency so if you look at this particles would concede that for example particles of Denmark reasons were playing with the cleaning efficiency of 75 % so 70 per cent 5 per cent of the part of the world class before well actually removed for particles larger than 15 micrometres cleaning efficiency was even higher 95 per cent aluminum bottles for all sizes were clean very well the cleaning efficiency of particles as small as 2 margaritas was already 85 per cent and particles larger than 6 as well playing with the efficiency of 97 per cent still particles did not playing that well not as good as aluminum particles but still already for particles of Denmark 50 per cent of 2 particles was cleaned and particles bludgeoned and 16 margaritas still cleaned but 95 per cent cleaning efficiency for
cleaning glass plates general trend was visible but the cleaning efficiency increases as a particle size small particles not clean as well as the logic when planning a 2nd time beginning efficiency and did not suddenly significantly improved as
a signal of the fall on a glass plates that during using may vary from last place to Closplint we have tested dependency all behave on the jet only cleaning efficiencies we measured several depths ranging from 230 to as low as 85 might cremated we did that using several glass plates with dust and compared to them by sending you go 1 step higher for every glass and measure the measurements should be very repeatable some variation occurred for a very small particles that that would also be an imaging we have seen the variation of the gap have no significant influence on the cleaning efficiency within the range that we have to
to check whether the ship-to-ship clear clean equally well over his home which we have the experience when measuring articles both in rock including directions and lateral to the cleaning direction the graph shows the results of the 2 men measurements they concede that the Blue Line which represents the cleaning perpendicular to the cleaning action shows a little bit lower cleaning efficiency for all particle sizes and is likely due to the pressure drop that find at the size of the should you should be in this day and that science of ship-to-ship treatment due to the figures of the blast the EC and escaped with results in professional all the relevant
factors that we have tested on the football great velocity variations if you various throughput between 1 and 100 million per 2nd that no significant influence on the cleaning efficiency we have also tested beauty and the results of the clean PT places are consistent with cleaning the glass furthermore we have deliberately charged place at electrostatic leave and we note that this did not significantly influenced the cleaning efficiency so let's
compare the results of their own obtained to the tires and the particle removal efficiency the cleaning efficiency on glass plates was in general very good for particles larger than 10 Denmark aluminum particles article removal efficiency of 79 per cent of tyrant was 90 per cent environmental best be achieved 74 per cent our time once set to 50 per cent of still particles we achieved 61 cent hit the target was somewhat higher 90 for particles larger than "quotation mark micrometres all particles we achieved particle removal efficiency of lodging and 95 per cent the time was set to 90 per cent results from
that place competing plans are very similar to the results of the blood now let's have a look at the
2nd set of that created or
altered role-playing In a picture on the left his seat and their opinions have on the left and the right to receive the roles for winding and unwinding form and in the middle Eocene an area picture variety shows a camera that we have used in this case as could others this use saying that because that was on all flying camera while we need in in this case an online camera possibility
1 the goal that we have set for narrowing playing integration in the world to rules 1st I would like to achieve results of comparable only in center with the offline as a measurement alone would like to use the parts and which is equipped for online measurements work if it's stationary we'd like to extend to followed with 2 3 on the mm regurgitated Katie black which is suitable for usage with the parts and measurement for particles that we're going to test we have selected environment and the government get will be said it's raining 15 minutes and 104 51
particle counter that we have used part sense is a hand-held measurement had basin glancingly like technology so comes from science and is reflected by the particles that are all the measurement had is merely position this means that we cannot do repeatable measurements before and after they cannot compare the before and after Lehman's 1 where 1 can only by statistic for the therefore for each measurement we take 30 samples before fleeing after cleaning industry statistics on a resolution of parts and a somewhat higher than the resolution living in democracy has it come to a resolution of 1 pixel is 8 . 5 micrometres by April 5 1 commuters we need at least 3 by 3 pixel to represent the particle to be able to distinguish it from the US so resolution 36 the measurements on
road to roll cleaning still in progress but let me show some initial results the grounds similar to the Russian shown before for dust particles we can see that from particles of aging Mokhtari was 80 per cent of the dust particles is clean and for particles larger than 150 moderates and even 92 per cent of the dust particles is clear aluminum particles will be even better results particles of a deep sense of a democracy and 90 per cent is clean and particles larger than 100 Michael even 95 per cent other the particles is clean this slide shows an
abstract of the major results as you can see we achieved very good results the cleaning portion to should process when dust particles from aluminum particles the results were still particles such somewhat lower but still very good and the initial results of the role to all lines show also very promising results the particles of 80 % my even a two-percent was clean for that particles of age might be was playing for aluminum smaller particles still needs we worked out because that also depends on the result you get from the engines this brings me to my conclusion the narrow cleaning technology has been effectively assessed as a non-contact cleaning very good results have been obtained for cleaning organic as well as inorganic materials moreover we have shown that the cleaning 7 burst to variations for example in that are fit through Boston the cleaning efficiencies depends on account of a combination of contamination and substantive and
finally we have validated Maryland measurements of particles a particle sizes and this show to be crucial in determining an accurate cleaning efficiency for a specific condemnation of such communication and like to
finalize the thanking you for your attention and acknowledging the European Union's of Framework Programme for defending my program of
