[0002] In order to protect the environment, denitrification processes are often added to current production processes, that is, selective catalytic reduction technology is used to denitrify emissions containing nitrogen oxides, reducing nitrogen oxides in emissions into nitrogen and water, thereby reducing damage to the environment. Conventional heating SCR denitrification equipment often heats emissions in a hot air furnace and then passes them into a denitrification device containing a catalyst.

[0003] A layered heating SCR denitrification equipment is disclosed in the Chinese patent application publication specification CN220071257U. The layered heating SCR denitrification equipment includes a denitrification tower, multiple catalyst partitions and multiple heating devices. The size of the fixing bar is adapted to the size of the fixing groove. The fixing bar is slidably engaged with the fixing groove in a adaptive manner. Each heating device can effectively ensure that the temperature in the entire denitrification tower is appropriate to complete the denitrification reaction. The heating device is easy to disassemble and easy to maintain.

[0004] Although the above scheme can be easily disassembled and repaired, the layered heating SCR denitrification equipment in the above patent is not convenient for adjusting the distance between each layer of partitions. The distance between the heating partitions in the above scheme is fixed with the isolation space, so that there is a temperature difference between the partitions, which reduces the practicality of the heating device. For this reason, we provide a layered heating SCR denitrification equipment to solve the above problems. Utility Model Content
