1、 Composition and working principle of complete equipment for dry feeding of powdered activated carbon

1. The complete set of equipment for automatic feeding of powdered activated carbon consists of a vacuum feeder, a variable frequency dry powder feeder, a storage bin, a level gauge, a vacuum pressure gauge, an electromagnetic valve, a pneumatic valve, an air compressor, a water injector device, an electrical control cabinet, and an automatic control system.

2. The vacuum feeding system sucks the powdered carbon into the hopper to reduce dust pollution; The variable frequency dry powder feeder adopts a double screw feeder to feed the powder, ensuring uniform and dispersed feeding with an accuracy within ± 3%.

3. Open the front and rear valves of the water injector. When negative pressure is formed inside the water injector, open the electric valve on the upper part of the water injector. At the same time, the dry powder feeding machine will automatically start working, and the powdered activated carbon will be added to the water injector. The water injector will mix the powdered activated carbon with water and put it into the feeding point.

II Dry dosing process

Feeding - storage - continuous quantitative addition of activated carbon - added to the feeding point by the jet injector.
