Powder is fed in, causing dust to fly
Thread Content
During production, powder material needs to be added; since the particles are quite small, dust is often generated, which affects the environment. In terms of process optimization, adding exhaust fans and bag filters has been considered; it should yield good results, but the investment required is high, so the boss definitely won’t agree to it. Do any of you have any tips? Mainly, it requires less investment but yields good results.
The best approach is to isolate the source of pollution from the outside world, so that dust won’t fly around, and to handle it through collection and treatment.
For the fine chemical industry, such dusty conditions are like a disaster; the amount of material added is only a few kilograms, and with all that wind and disturbance, it all gets blown away.

It is a sealed, automatic feeding device for reaction vessels, designed to replace manual feeding of powders and solid particles into the reactors. The device is connected to the reactor via sealed flexible connections, which prevents dust from being generated during feeding; this improves the utilization rate of materials. The sealed connection between the device and the reactor also stops organic solvents from leaking out of the reactor during feeding. Feeding is fast and efficient, thereby reducing the workload on employees. The equipment is controlled by a PLC and can be connected to the workshop’s DCS control system, allowing the workshop to monitor its operating status as well as control its start and stop. It has been put into use in the production of the pesticide active ingredient thiamethoxam, replacing the manual addition of oxadiazine and ultra-fine potassium carbonate to the reaction vessel.
