Overview

GCDM series High Clean Air Bag Dust Collector is a practical and efficient product with independent intellectual property rights developed by our company on the basis of summarizing the practical experience of ESP and long bag low pressure pulse bag dust collector widely used in metallurgy, electric power, building materials and solid waste industries over the years, and drawing on the experience of advanced boiler dust removal technologies from abroad. It can better adapt to the combustion characteristics and flue gas characteristics of domestic boilers and industrial boilers; The bad conditions that may occur in the running process of the boiler are fully considered, such as combustion-supporting with oil, abnormal smoke temperature, "four pipe" burst etc.

Working mechanism:

The dusty gas passes through the inlet horn of the dust collector, and the inlet horn is provided with a grading air distribution plate inside. Some large particles of dust fall directly into the hopper after separation through the air distribution plate, and the rest dust enters the filter area of the middle case with the air flow under the guidance of the diversion system, and is adsorbed on the outside surface of the filter bag. The filtered clean gas is discharged through the filter bag through the upper box and through the exhaust duct.
The working principle of the ash cleaning system: the compressed air transmits the filtered air through the gas pipeline to the storage tank of each pulse valve. Then the compressed air is sprayed into the filter bag instantaneously through the nozzle at the lower part of the fixed spray pipe to achieve the purpose of ash cleaning.

Main component
It is composed of high clean air chamber, middle case,  hopper, air distribution system, air inlet and outlet flue, pulse cleaning system, heating system, anti-blocking system, insulation system, electrical control system etc.
