Energy-saving cleaning system

An energy-saving cleaning system that cleans the fluid flowing in the circulation pipeline in the circulation equipment. It includes a filter device that removes large particle size dirt in the fluid, uses the internal rotation effect to separate the fluid into a combination of dirt that needs to be discharged, and returns it to the circulation. A water purification diverter for the recyclable fluid and the fluid to be activated in the storage device of the equipment, a flow rate control device for controlled pressurization of the fluid to be activated so that the fluid to be activated has a predetermined flow rate and fluid pressure, and a flow rate control device for the fluid to be activated with a predetermined flow rate and fluid pressure. The fluid to be activated passes through and is activated into a nano-activation device containing negative ion fluid. This utility model is mainly designed for the cooling water circulation equipment of the central air-conditioning system. The cooling water removes suspended dirt and impurities and quickly nano-scales it for recycling, providing A brand-new device that takes into account environmental protection, energy saving and water saving.
