The slurry filter is clogged and difficult to clean

This post was last edited by Yongge, how are you? on 2010-12-15 at 09:52. Reply to 1# Tevis: I don’t think it’s a matter of which type of filter to use. It’s evident that the proportion of impurities in the slurry exceeds the filter’s capacity. Simply increasing the size of the filter to expand its filtering area or switching to another type of filter is clearly not a viable solution. In fact, the main issue lies in the causes of impurity formation in the slurry: 1) Poor dispersion during the initial polymerization stage, resulting in uneven particle formation; 2) Formation of large particles due to collisions between high-energy particles during polymerization; 3) Accumulation of polymers on the reactor walls, leading to the detachment of these polymers and thus the formation of impurities. In short, for some problems, it’s necessary to identify the root cause from a technical perspective in order to address the actual issue :) :victory:.

I hope those with experience can offer some guidance. As mentioned in the first comment, there are indeed issues with the manufacturing process, but they cannot be resolved in a short time; for now, the only option is to improve the filters.

That makes sense; the filter can be made automatic, so there’s no need for manual cleaning, and thus no problem with clogging. The choice of which type of automatic filter to use depends on many parameters. Our company can provide mechanical scraper-type automatic filters, mechanical backwash automatic filters, and bag-type automatic backwash filters. However, the prices are all quite high; if your budget allows, you can give it a try

Could the guy upstairs send me some information on the equipment used in your factory? It would be helpful to have a comprehensive understanding of why slurry vibration screens aren’t very effective, as well as information on drum screens. I hope to obtain detailed information.

I forgot to send my email address: ling*7576@163.com

Brother upstairs, I’ve already sent you an email.

In current PVC processing, centrifuges are often followed by backwash filters or self-cleaning filters; in some cases, self-cleaning filters are used for direct filtration

Hehe, add filters – 10 units of the same size connected in parallel; I’ve seen that done before. Alternatively, use http://www.filtration.cc/selfcleaningfilters/auto%20filters.html

Severe sticking to the reactor wall, along with the residue caused by the excessive shedding of self-polymer, is the real root of the problem. To improve the coating effect in the kettle
