Description

Technical Field

[0001] This utility model relates to the field of flue cleaning technology, specifically a novel flue cleaning device. Background Technology

[0002] In the flue gas outlet of the reactor in a waste incineration power plant, due to the reduced boiler load and lower flue gas velocity, some dust will accumulate. The dust contains quicklime powder, which absorbs moisture and hardens. Over time, this will lead to dust accumulation, increasing the resistance of the flue gas system. In severe cases, the boiler needs to be shut down for manual cleaning.

[0003] Traditional flue cleaning devices often result in uneven cleaning, and some stubborn ash deposits may not be effectively removed, leading to an increase in the frequency of cleaning. Some traditional cleaning devices may also cause mechanical wear on the flue during the cleaning process, reducing the service life of the equipment. Utility Model Content

[0013] Compared with the prior art, this utility model provides a novel flue cleaning device with the following advantages: The novel flue cleaning device has three second air pipes installed at the bottom of the flue, each with six nozzles evenly spaced. This effectively removes soot from the flue, improving cleaning efficiency. A ball valve is connected to the second air pipe at the bottom of the flue to adjust the amount of air blown from the nozzles. A solenoid valve is connected to the bottom of the ball valve, allowing for intermittent air blowing for flue cleaning, saving energy. A one-way valve is connected to the second air pipe via an air reservoir.
