Each of the hot water tank 1, water tank 2, acid tank 3, and alkali tank 4 is equipped with a level gauge and a second temperature sensor, enabling real-time monitoring of the liquid level and temperature inside each tank. The hot water tank 1 can use its internal hot water for pre-rinsing; the water tank 2 can use water to rinse away detergent residue adhering to the pipeline; the acid tank 3 can perform acid circulation cleaning; and the alkali tank 4 can automatically inject alkaline detergent for cleaning. The input ends of the hot water tank 1, water tank 2, acid tank 3, and alkali tank 4 are all... A return pipe 5 is connected to each of the four return pipes 5, and a first valve 6 is connected to each of the four return pipes 5. A connecting pipe 7 is connected to both the acid tank 3 and the alkali tank 4. The ends of the two connecting pipes 7 are respectively connected to a concentrated alkali tank 10 and a concentrated acid tank 9. Both the concentrated alkali tank 10 and the concentrated acid tank 9 are equipped with diaphragm pumps 8. The diaphragm pumps 8 use a diaphragm to separate the liquid being transported from the piston and pump cylinder, thereby protecting the piston and pump cylinder and effectively transporting acid and alkali. The concentrated acid tank 9 is connected to the acid tank 3 via a connecting pipe 7, and the concentrated alkali tank 10 is connected to the alkali tank 9 via a connecting pipe 7, allowing for the replenishment of acid and alkali detergents inside the acid tank 3 and alkali tank 9.

A second valve 23, a third valve 12, and a cleaning pump 13 are installed between the cleaning pipe 11 and the cleaning equipment 15. The cleaning pump 13 can deliver detergent into the cleaning equipment 15, enabling effective cleaning. A heat exchanger 14 is installed on the cleaning pipe 11, allowing heat exchange between steam and the detergent in the cleaning pipe 11, maintaining a certain temperature for cleaning and improving the cleaning effect.
