[0002] Boiler return water refers to water that flows out of the boiler, cools, and then returns to the boiler. During boiler operation, water flows from the boiler outlet, is transported through pipes to external equipment, and then enters the boiler's return water outlet through another pipe, forming a loop. Steam boilers are used in the explosives production process, generating large amounts of return water. This return water carries many impurities, such as iron filings, colloids, and dissolved salts. After the boiler water circulates multiple times, the accumulated impurities become excessive and need to be removed before further circulation can continue. At the same time, additives such as softeners and corrosion inhibitors are added to the boiler water to extend the service life of the boiler and pipes. Therefore, it is necessary to develop a circulation system that can remove impurities from boiler return water and allow the addition of auxiliary agents to meet this need. Utility Model Content
