The smoke components discharged by the household garbage incineration power plant are very complex, and contain various environmental pollution components such as acid gases (HCl, HF, SOx), nitrogen oxides (NOx), particulate matters, organic matters (including dioxin), heavy metals and the like, so how to control the discharge of the pollutants becomes an important research topic of the household garbage incineration power plant. The lime slurry desulfurization technology is the most mature and widely applied desulfurization technology at present, the requirement on the lime slurry desulfurization technology at home and abroad is higher, and the emission concentration of SO2 in power plant smoke in the key areas (Jinjin Tang, long triangle, zhu triangle, and two-line metropolitan areas) at home is reduced to below 50 mg/m. At present, the existing pulping system in the garbage power generation industry in China basically comprises a pulping tank, wherein the top of the pulping tank is directly filled with water and quicklime to be mixed to prepare lime slurry, however, a large amount of lime particles are often adhered to the inner wall of the tank body and a stirring paddle, the adhesion force of lime is stronger due to the wet environment in the tank, and finally a series of problems such as overhigh load of a motor (5) and difficult pulping are caused, equipment has to be stopped, and the lime cannot be cleaned in the tank in a timely manner, so that the corresponding environment-friendly risk of timely supplying a desulfurizing agent is brought.

However, manual cleaning is time-consuming and labor-consuming, and has the safety risks of closed space operation and eye injury caused by lime slurry, so that the safety, environmental protection and stability of operation of most household garbage incineration power plants in China are a great problem for how to eliminate the serious safety and environmental protection hidden danger and how to ensure the normal operation of environmental protection equipment at any time.

Aiming at the situation of China, it is necessary to design a pre-water inlet and flushing device for a pulping tank of a household garbage incineration power plant so as to ensure the normal operation of environment-friendly equipment and reduce the manual maintenance cost of the household garbage incineration power plant to a certain extent.
