Pulsed gas generator

The invention discloses a pulsed gas generator and is intended to provide a pulsed gas generator that can use just a small flow of gas to enable pulsed aeration of releasing a large flow of gas instantly and uniformly to generate large bubbles and that can effectively prevent aeration failure due to gas passage blockage caused by sludge settlement to have longer service life. The pulsed gas generator comprises a housing that has an inner chamber forming a gas collection chamber with a bottom opening, a gas collection line is disposed in the gas collection chamber and has a first opening communicated with the gas collection chamber and a second opening communicated with the outside of the housing, a lowest point of the gas collection line is positioned below the first opening and the second opening, and a lowest point part of the gas collection line is provided with a sludge discharge pipe communicated with an inner chamber of the gas collection line. 本发明公开了种脉冲气体发生装置，旨在提供种仅需要较小流量的气流，即可实现瞬间均匀释放大流量气体产生大气泡的脉冲曝气效果
