Before work, firstly, filling hydrogen peroxide into the hydrogen peroxide storage tank 201 through a No. seven hand valve below the base of the hydrogen peroxide storage tank 201, and closing a No. seven hand valve at the downstream after filling; the upper extrusion gas port is connected to the first extrusion pipe 111, and the middle stabilizer supply port is communicated with the stabilizer supply module 400; in the normal use process, the seventh stop valve at the downstream of the base of the hydrogen peroxide storage tank 201 is opened, and the tenth stop valve at the upstream of the stabilizer inlet is in a closed state, so that the stabilizer does not enter the hydrogen peroxide storage tank 201; when the third stop valve upstream of the extrusion gas port is opened to allow the high-pressure extrusion gas to enter the hydrogen peroxide storage tank 201, the hydrogen peroxide in the hydrogen peroxide storage tank 201 is extruded by the high-pressure gas, and the hydrogen peroxide is discharged out of the hydrogen peroxide storage tank 201 in a high-pressure manner and supplied downstream.
