What is the effectiveness of robot cleaning in polymerization reactors?

I really haven’t seen it before; we have people going down there to clean the pots

It’s not bad; it’s much safer and more convenient than working manually. We acquired the high-pressure cleaner in 2009, and its maximum cleaning pressure is 800 KG. With different nozzles available, it can be used for cleaning reactors as well as shell-and-tube heat exchangers and similar devices.

High-pressure washer with a maximum cleaning pressure of 800 KG; equipped with various nozzles, it can be used for cleaning reactors as well as shell-and-tube heat exchangers and similar devices. But the large pieces need to be taken down by people

Automatic high-pressure flushing – is that just a robot cleaning the reactor?

　By using ultra-high-pressure water of 800 KG, along with adjustable nozzles and rotating spray heads, it is possible to carry out automatic or semi-automatic hydraulic cleaning of the reactor, as well as cleaning of the reflux condenser at the top of the reactor and the vapor pipelines. This technology is widely used in the imported PVC paste production facilities; it allows for cleaning of each reactor individually. After years of use, it has proven to be highly effective. This technology is particularly suitable for newly installed facilities and equipment, where the polished interior surfaces have not been damaged (in theory), making it efficient and capable of preserving those polished surfaces. However, it cannot eliminate the problems caused by scratches on the polished surfaces resulting from regular maintenance over many years, which are sources of sticking issues within the reactor. In summary, despite the existence of various anti-sticking tank technologies and tank cleaning methods, thorough manual cleaning of the tanks is still required after a certain number of uses. This places high demands on the personnel responsible for tank cleaning. Most manufacturers rely on their own workers to clean the polymerization tanks, rather than using professional tank cleaning and polishing specialists. Due to insufficient measures to protect the polished surface of the tank’s interior, this can result in scratches on the inner surface of the tank, leading to microscopic scratches and indentations, as well as a decrease in surface roughness and smoothness. In severe cases, this can result in sharp scratches on the inner surface.

A program is then set for the cleaning machine, causing the nozzles to move to these designated points one after another in order to clean the inner walls of the tank. For different containers, it is necessary to reset them according to their internal dimensions and structure.

Reply to 7# lwg0719: If that’s the case, bulk polymerization would have been achieved by now. Three flushing points are installed at the high, medium, and low positions of the polymerization reactor; a flushing time is set, and the DCS automatically executes the flushing procedure. The flushing nozzle is driven by compressed air to rotate (in both horizontal and vertical directions). But I think this can’t be considered a Cheongbu robot either. As I understand it, cleaning a reactor involves removing polymers that cannot be cleared by washing and are firmly stuck to the reactor walls.
