Dust filter

2.  Structure and working principle
SD single pulse bag Filter is composed of the shell, ash bucket, ash exiting devices, bracket and pulse cleaning system. The dust sucked into the dust filter firstly hits the blocking plate at the end of the air inlet, and then the dust particle falls in the dust hopper directly as the inertia of dust plays the role of pre-filter. The gas flow in the dust hopper then goes up and passes through the filter bag equipped with internal skeleton.  The dust is caught on outer surface of the filter bag and the cleaned air enters the clean room of the top of the bag, and then is exhausted from the air outlet.  Indoor dust filtering bags are divided into several platoons, dust cleaning of each row is conducted in turn within a given time interval. When the pulse valve is opened, a high-pressure air is injected into bags immediately to remove dust on the surface of bag. The pulse jet width and cleaning cycle of each row of bags is controlled automatically and continuously by the specialized cleaning process controller. The structure and working principle of dust Filter are shown in appendix.

SD single pulse bag filter can installed outdoor. There are eight specifications based on numbers of bags needed.  The diameter of the bags is 130 mm, the length is 2000 mm.
SD single pulse bag filter can operate on either negative or positive pressure, and there is no any change for the structure of its body. The dust collecting efficiency could be up to 99.9%, and dust concentration of purified gas is less than 100 mg/m3(standard). The main technical performances of this series can be found on the appendix.
When used at the temperature

Dust filter has small cubage, high capacity of treatment, compact structure, easy and reliable cooperation.
