s1, physically loosening or dredging the blocking block in the heat exchange module of the air preheater to be cleaned;

s2, hoisting the heat exchange module processed in the S1 into a cleaning tank 1, and cleaning by a mode 1 or a mode 2:

mode 1: injecting cleaning liquid into the cleaning tank 1 to enable the height of the liquid level 21 in the cleaning tank 1 to reach or exceed the height of the position of the drain pipe 8; the water drainage pipe 8, the pump 7 and the water inlet pipe 6 are sequentially communicated by controlling the opening and closing of each valve, the pump 7, the invasive ultrasonic vibration plate 14 and the ultrasonic generator 2 are started, the ultrasonic frequency is adjusted to a proper interval (the ultrasonic frequency is set according to the difference of the cleaned objects), and the pump 7, the invasive ultrasonic vibration plate 14 and the ultrasonic generator 2 are closed after the target cleaning time; then, the drainage pipe 5, the pump 7 and the outer discharge pipe 9 are sequentially communicated by controlling the opening and closing of each valve, and the pump 7 is started to discharge the dirty cleaning liquid; then, injecting the cleaning solution again for cleaning; thus, the cleaning liquid in the cleaning tank 1 can be ensured to be always in a relatively clean level repeatedly;

mode 2: injecting cleaning liquid into the cleaning tank 1 to enable the cleaning liquid to immerse the heat exchange module; the sewage discharge pipe 5, the pump 7 and the water inlet pipe 6 are sequentially communicated by controlling the opening and closing of each valve, the pump 7, the invasive ultrasonic vibration plate 14 and the ultrasonic generator 2 are started, the ultrasonic frequency is adjusted to a proper interval (the ultrasonic frequency is set according to the difference of the cleaned objects), and cleaning is carried out; meanwhile, the cleaning liquid flowing into the pump 7 from the sewage draining pipe 5 is filtered;

s3, lifting the cleaned heat exchange module to the outside of the cleaning tank 1, and drying to finish cleaning;

optionally, during cleaning, the cleaning liquid is heated to a suitable temperature by the heating element 11.

Referring to fig. 13 to 15, as another embodiment, the difference is mainly that: the jet pipe network 3 and the sewage pipe network 4 are arranged side by side and are at the same height. Each longitudinal pipe is internally provided with a partition baffle plate 12 for partitioning each longitudinal pipe, and a horizontal pipe at the outermost side and a horizontal pipe at the middle position are partitioned to form a jet pipe network 3 and a sewage pipe network 4 which are not communicated with each other. Therefore, circulation flow can be formed in the cleaning tank, and full-area stirring flow is realized; the position of the cleaned object can be turned to realize uniform scouring on the cleaned object. Optionally, both ends of the sewage pipe 5 are communicated with the pump 7, so that the suction difference of the sewage seams in the length direction of the transverse pipe can be reduced. In addition, referring to fig. 16-18, as another embodiment, a partition plate may be disposed in each horizontal pipe to partition each horizontal pipe, and each partition is located between 2 adjacent horizontal pipes, so as to form a jet pipe network 3 and a drain pipe network 4 which are distributed in the left and right direction and are communicated with each other.

The foregoing examples are set forth to illustrate the present invention more clearly and are not to be construed as limiting the scope of the invention, which is defined in the appended claims to which the invention pertains, as modified in all equivalent forms, by those skilled in the art after reading the present invention.
