Abstract
Description
technical field
[0001] The invention relates to a pulse valve capable of generating pulse air flow. Background technique
[0002] The pulse valve is an important device of the ceramic high-temperature and high-pressure fly ash filter element online back-blowing cleaning system in the Shell pulverized coal gasification device. Solid impurities (filter cake). However, the existing pulse valve is driven by an electromagnetic drive mechanism to open and close the valve, which cannot detect the valve opening and closing time, and cannot realize continuous and automatic valve opening and closing state control. Contents of the invention
[0003] In order to solve the technical problem that the existing pulse valve cannot realize the automatic opening and closing of the valve and the detection is inconvenient, the present invention provides a pneumatic pulse valve which can be continuously and automatically opened and closed.
[0004] Technical solution of the present invention:...
