Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of power plant boiler cleaning equipment, and particularly relates to a heating boiler flushing device. BACKGROUND

[0002] A power plant boiler is one of the three main devices in a thermal power plant. It is composed of a boiler body and auxiliary equipment. It uses the heat generated by the combustion of fuel (such as coal, heavy oil, natural gas, etc.) to heat water into superheated steam with a certain temperature and pressure to drive the steam turbine generator to generate electricity.

[0003] Due to the influence of water quality, scale will be generated in the boiler, which will affect the heating of water, prolong the heating time, and ultimately lead to low power generation efficiency.

[0004] At present, the existing boiler flushing device for power plants has a simple structure, and manual water injection is required during flushing, which is low in use efficiency and cannot control the flushing water volume, and is very inconvenient to use.

[0005] As disclosed in patent No. 202120391889.6, a boiler flushing device for a power plant includes a boiler body, a boiler pipe arranged at the top of the boiler body, a fixing plate arranged at the top of the boiler pipe, a water collecting tank arranged at one side of the boiler body, a water inlet pipe arranged at the side of the water collecting tank away from the boiler body, a water outlet pipe arranged at the inside top end of the water collecting tank, a control valve arranged at the middle of the water outlet pipe, a valve plate arranged inside the control valve, and a valve rod arranged at the top of the control valve. The boiler flushing device for a power plant adds a control valve at the middle of the water outlet pipe, and the inside of the control valve is provided with a sealing gasket and a valve plate. When the water outlet pipe is conveying water, the valve rod can be rotated by rotating the handle, and the rotation of the valve rod can adjust the opening angle of the valve plate to control the water volume of the water outlet pipe. The water collecting tank is added at one side of the boiler body, and the water collecting tank stores water in the inside through the water inlet pipe. When the boiler body needs to be flushed, the water pump can convey the water in the water collecting tank into the water outlet pipe, and finally the water enters the water spray head to flush the inside of the boiler body. Although it can play a cleaning role, the scale on the boiler is difficult to remove by flushing after a long time of accumulation, and there are still deficiencies in the prior art. SUMMARY
