Pulse aeration device and membrane module

Abstract

The present disclosure relates to the technical field of environmental water treatment, and provides a pulse aeration device and a membrane module. The device includes: a box body, which forms an air inlet and multiple air outlets connected to the accommodating space; a partition structure integrally formed with the box body, which encloses multiple aeration chambers and air supply chambers, including air supply sections connected to the air inlet and symmetrically arranged on opposite sides of the multiple aeration chambers; an aeration assembly is provided in each aeration chamber; the aeration assembly includes: a central tube, which is fixedly penetrated with air outlets to enter the corresponding aeration chamber; a cylindrical air collecting cup, which is sleeved outside the central tube, maintains a gap between the upper end and the top wall of the box body and forms an air collecting port higher than the air inlet; wherein the partition structure is symmetrically provided on opposite sides with air vents that connect each aeration chamber to the air supply sections on both sides. The structure of symmetrical air intake on both sides of each aeration chamber through the air supply chamber improves air supply and aeration efficiency; and the main structural parts are integrally formed, so only the aeration assembly needs to be installed, which effectively improves installation efficiency and structural reliability.
