A pulse bag filter for gas purification

Abstract

The invention relates to the technical field of gas purification, and discloses a pulse bag filter for gas purification, which includes a box body, a flower plate is fixedly installed inside the box body, and a clean air chamber is arranged above the flower plate. A filter element is sleeved on the flower plate, an air jet main pipe is arranged in the inner cavity of the clean air chamber, and an air collecting pipe is arranged in the inner cavity of the clean air chamber. In the present invention, a Venturi tube and a gas collecting pipe are arranged above the filter element, and the purified gas flowing out of other filter elements is converted into energy in the gas collecting pipe to form a negative pressure above the filter element when flowing through the current filter element. Under the action of air pressure, the flow rate of gas in the filter element is increased, thereby increasing the air pressure difference inside and outside the filter element, so that the gas in the box is offset to the outer wall of the filter element, so that the gas entering all parts of the filter element The amount is uniform, which improves the uniformity of gas distribution throughout the filter element and reduces the local wear of the filter element.

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...
