Pulsed bag-type dust collector for gas purification

Abstract

The invention relates to the technical field of gas purification, and discloses a pulsed bag-type dust collector for gas purification, which comprises a box body, a pattern plate is fixedly arranged in the box body, a gas purification chamber is arranged above the pattern plate, a filter element is sleeved on the pattern plate, a gas injection main pipe is arranged in an inner cavity of the gas purification chamber, and a gas collecting pipe is arranged in an inner cavity of the gas purification chamber. A venturi tube and the gas collecting pipe are arranged above the filter element, purifiedgas flowing out of other filter elements is subjected to energy conversion in the gas collecting pipe, a negative pressure area is formed above the filter element when the purified gas flows throughthe current filter element, and the flow speed of the gas in the filter element is increased under the action of gas pressure; therefore, the air pressure difference inside and outside the filter element is increased, air in the box body deviates towards the outer wall of the filter element , the amount of air entering the filtering piece everywhere is uniform, the air distribution uniformity of the filtering piece everywhere is improved, and local abrasion of the filter element is reduced.

Description

technical field [0001] The invention relates to the technical field of gas purification, in particular to a pulse bag filter for gas purification. Background technique [0002] The dust-laden gas enters the filter chamber of each unit through the diversion pipe. Since the bottom of the filter bag is designed to have a sufficient and reasonable distance from the top of the air inlet, the air flow is distributed through proper diversion and natural flow to achieve uniform air distribution in the entire filter chamber. Particle dust is separated by natural sedimentation and directly falls into the ash hopper, and the remaining dust is guided by the diversion system, enters the filter chamber with the airflow, and is adsorbed on the outer surface of the filter bag. The filtered clean gas is discharged through the filter bag through the clean air chamber and the air outlet flue. The filter bag uses compressed air to spray and clean the dust. The dust cleaning mechanism is compos...
