High-efficient frequency-conversion pulse pipeline cleaning machine

The utility model relates to a high-efficient frequency-conversion pulse pipeline cleaning machine. When the pulse cleaning is carried out, a CPU master control unit (17) is used for controlling a gas high-frequency solenoid valve (2) and a liquid high-frequency solenoid valve (7) to sectionally inject the gas and liquid into a cleaning pipeline (25) in different frequencies; liquid and gas, and then liquid and gas are generated in the cleaning pipeline (25); under the effect of high-pressure gas, an air explosive effect is achieved by the liquid and an inner wall of the pipeline is brushed and shocked; when atomizing cleaning is carried out, the gas high-frequency solenoid valve (2) and the liquid high-frequency solenoid valve (7) are controlled to be synchronously opened by the CPU master control unit (17), the pressure on the sections of a gas pipeline (23) and a liquid pipeline (24) is quickly increased, the gas high-frequency solenoid valve (2) and the liquid high-frequency solenoid valve (7) are quickly closed and opened and then closed and opened when a preset value is reached, and an uninterrupted jetting atomized flow is generated for atomizing and cleaning the cleaning pipeline (25).
