Overview
The CMC warehouse top dust collector is a device that uses the principle of bag filtration to separate gas and ash, remove exhaust gas outward, and maintain normal pressure inside the container. It is suitable for placement at the top of various powder storage warehouses, especially for the top of the receiving bin in pneumatic conveying processes.
Working mechanism
When the CMC series pulse bag filter is in operation, the dusty gas enters the dust collector through the exhaust hole at the top of the ash silo. Coarse dust particles directly fall into the ash silo, while fine dust particles enter the middle case body with the gas flow. The dust accumulates on the outer surface of the filter bag, and the filtered gas enters the upper case body through the bag mouth and the exhaust duct to the exhaust outlet of the outlet fan.
Main component
The dust collector is composed of upper case, middle case, spray device, filter bag and bag cage, pulse control system etc.
Model description
Range of Gas flow processing
500~10000m3/h, the outlet emission concentration is lower than 30-5mg/Nm3.
Applicable industry
The application of dust and fly ash storage in industries such as metallurgy, building materials, electricity, light industry, chemical industry and solid waste.
Technical innovation points:
● Single-machine modular structure
● Fixed pipe blowing technology
● Inlet and outlet temperature display , ash cleaning and unloading instructions;
● Easy maintenance and repair, repair and bag change can be carried out in separate rooms under the normal operation of the system fan and dust collector;
● Pulse controller system;
● Adapt to a wide range of changes in the properties of dusty gases;
