Description

Technical Field

[0001] This utility model relates to the field of denitrification devices, specifically a denitrification device that is easy to maintain. Background Technology

[0002] Boiler exhaust gas refers to a pollutant emitted from gases, liquids, and powders in a boiler. Direct discharge can cause harm, therefore, a denitrification device is needed to treat the exhaust gas. A search of application CN202323568292.2 reveals a maintenance-friendly denitrification device comprising a frame, a denitrification cylinder fixedly installed inside the frame, and conical hoods fixedly installed at both ends of the denitrification cylinder via fasteners. A flue gas outlet pipe is fixedly installed at the top of the conical hood above the denitrification cylinder, and a discharge pipe is fixedly installed at the bottom of the conical hood below the denitrification cylinder. This maintenance-friendly denitrification device aims to achieve denitrification... While offering better performance and easier maintenance, the device incorporates a rotating assembly. When flue gas is introduced into the denitrification cylinder via an induced draft fan, the impeller causes the central shaft to rotate within two sets of fixed rods, which in turn drives the catalyst blocks to rotate synchronously. This, combined with the U-shaped tube and nozzles, ensures more thorough mixing of the medium, resulting in better denitrification. The segmented design also facilitates replacement and maintenance. However, the above description has the following drawbacks in practical use: the device is not easily adjustable to clean the inner wall structure according to the device's dimensions, thus limiting its maintenance. Therefore, a more practical and easily maintainable denitrification device needs to be designed. Utility Model Content
