Low-frequency and low-pressure control energy-saving method suitable for pulse valve of dust remover

The invention relates to the technical field of valve control, and particularly discloses a low-frequency and low-pressure control energy-saving method suitable for a pulse valve of a dust remover, which comprises the following steps of: 1) changing the injection frequency of the pulse valve, and reducing the pulse frequency in unit time; 2) changing the valve opening time of the pulse valve, and stabilizing the pressure difference of the dust remover; (3) the injection pressure of the pulse valve branch air cylinder is controlled, and stable injection pressure is obtained; (4) the dust remover operates under the stable pressure difference, and the blowing interval time of the pulse valve is gradually adjusted with second as the unit; according to the invention, the operation mode of the conventional pulse valve is changed, and the valve opening frequency, pressure control and valve opening time of the pulse valve are reasonably controlled, so that the service life of an injection part is prolonged, the opera
