Description

Technical Field

[0001] This utility model relates to the field of denitrification equipment technology, specifically a denitrification device for waste incineration power generation. Background Technology

[0002] Waste incineration power generation can realize the resource utilization of waste. After incineration, the waste can be processed to obtain a variety of energy sources. The high-temperature steam generated by combustion can drive a steam turbine to generate electricity for urban use. At the same time, the heat generated during combustion can also be used for heating, recycling, and other purposes. In this way, the energy contained in waste can be fully utilized, reducing dependence on traditional energy sources and improving energy efficiency.

[0003] A search revealed a Chinese patent publication number, CN222871627U, which discloses a flue gas denitrification device for waste-to-energy incineration, comprising: a main structure; the main structure includes a filter chamber and a denitrification chamber, with an air inlet pipe located at the lower end of one side of the outer wall of the filter chamber and an air outlet pipe located at the lower end of one side of the outer wall of the denitrification chamber; a filter assembly disposed within the filter chamber; the filter assembly includes a filter screen plate installed within the filter chamber; and a denitrification assembly disposed within the denitrification chamber; the denitrification assembly includes a spray pipe and a catalytic basket installed within the denitrification chamber for spraying urea solution, which ensures good denitrification effect while preventing large particulate impurities from accumulating inside the equipment and causing blockage.

[0004] Although the aforementioned patent can treat gas denitrification, the aforementioned flue gas denitrification device for waste-to-energy incineration still has the following problems: Since the device directly stores urea solution inside the solution chamber and then pumps it out for spraying to treat gas denitrification, in actual use, due to the lack of an effective disturbance structure, the solution is prone to concentration stratification and local deposition due to long-term static storage. Especially when the temperature fluctuates or the solution is stored for a long time, crystallization and precipitation are more likely to occur, thereby affecting the uniformity and stability of the urea solution, causing uneven spray concentration during subsequent spraying, and thus affecting the sufficiency and stability of the denitrification reaction. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content
