The single pulse bag filter is divided into single pulse bag filter and chamber pulse bag filter according to the model. It is mainly designed and manufactured according to the characteristics and working principles of dust contained in flue gas and dust such as power plant boiler, industrial boiler, steel production, cement manufacturing, non-ferrous metal production process, chemical raw material production, machinery manufacturing, garbage combustion, etc.

The single pulse bag filter is mainly composed of a filter chamber, an ash storage chamber and an exhaust chamber. It is divided into three steps: filtering the dusty gas, dust and discharging the purified air to complete the separation of powder and gas. It is suitable for filtering all kinds of dry and dusty gas, and the dust removal effect can reach 99% after the dust gas is filtered.

Working principle of single pulse bag filter

According to the characteristics of the dusty gas, the single pulse bag filter adopts different materials to meet the filtering requirements. The dust enters the filter chamber with the gas under negative pressure. The large particle dust falls into the ash storage chamber during the floating process. The small dust is blocked on the outer surface of the filter bag when the accompanying gas passes through the filter bag. The filtered clean gas rises to the exhaust chamber and passes through the filter chamber The fan is directed to the outside.

Single pulse bag filter adopts on-line dust cleaning, which belongs to small pulse bag filter equipment. It is suitable for installation environment with small air volume and small filtering area. The chamber pulse bag filter adopts multi chamber dust cleaning one by one, which has the characteristics of large air volume and filtering area.

The dust cleaning device of single pulse bag filter is to set the automatic back blowing dust cleaning time under the condition of dust cleaning effect of air source. With the accumulation of small dust on the surface of filter bag, the dust layer gradually forms. When the dust cleaning time is reached, the pulse valve at one end of the filter bag is opened, and the air flow is ejected to shrink, and the dust on the surface of the filter bag is shaken off by the reverse pressure from inside to outside.
