Example Embodiment
[0017] The method of the present invention uses acid regeneration unit equipment and additional tee 3 and high pressure acid and alkali resistant connecting hose 2 to establish a lye washing circulation loop without external equipment, forming an internal circulation type pipeline acid scale cleaning process. The specific embodiments of the present invention will be described in detail below with reference to FIG. 1:
[0018] 1. The bottom of the pre-concentrator 8 of the acid regeneration unit is the lye solution pool, and the first lye is composed of the circulating pump 11, the pre-concentrator circulating filter 12, and the 30-meter circulating pipe 13 of the pre-concentrator to be cleaned of acid scale Flush the circulation loop. Connect the two connection ports of the added tee 3 to the two spray guns, and the other connection port is connected to the connecting hose 2, using the feeding pump 10, the feeding filter 5, and the 40-meter feeding pipe to be cleaned of acid scale...
