Summary
The structure of bag deduster is compact. It runs steadily and is convenient to install and repair. It is an ideal small and medium dedusting equipment. The dusty gas enters the deduster from the bottom of the deduster and goes through the part flow system. The big particles are separated into the ash hopper and the gas streams flows evenly up to the filter bag area. The filter bag intercepts the dust particles. The clean gas will be discharged from the top of the deduster.
This deduster is a low power dedusting equipment. It can remove the ash by low-pressure, short pulse spray for kinds of tectorial felt filter bag. The removing effect is good and dedusting efficiency is high. Supported by filter bag suitable of kinds of temperatures, it can work normally from normal temperature to 300centigrade. It is an ideal bag deduster for every trade to dedust dusty gas.
