Description

Technical Field

[0001] The utility model relates to the field of injection valves, in particular to a decoking agent spraying device. Background Art

[0002] Most of my country's industrial boilers are mainly coal-fired. In recent years, in order to save costs, factories often use low-quality coal for boiler combustion. These low-quality coals are prone to cause problems such as coking on the heating surface during the combustion process. When the boiler heating surface is coked, the heat transfer capacity decreases, and the heat absorption in the furnace decreases, resulting in increased flue gas temperature, increased boiler exhaust loss, and reduced boiler thermal efficiency. In severe cases, it may cause a tube burst accident on the heating surface.

[0003] A decoking agent spraying device (CN209735432U) is currently available. This device addresses the problem of manual decoking, which often requires multiple quantitative additions. Manual operation can easily lead to significant time interval and dosage deviations, resulting in reduced decoking effectiveness and uneven decoking. A support plate is mounted above the boiler, with a medicine storage tank mounted on its upper end. A stirring motor protective housing is mounted on its upper end, with a stirring motor mounted within the housing. A support block is mounted on the lower end of the stirring motor. A medicine feed pipe is mounted on the upper end of the medicine storage tank, with a stirring rod mounted within the tank. Stirring blades are mounted on both sides of the stirring rod. Guide plates are mounted on both sides of the medicine storage tank. A guide pipe is mounted below the medicine storage tank, with a solenoid valve mounted on the outside of the guide pipe.
