[0002] Silicon carbide is widely used due to its stable chemical properties, high thermal conductivity, small thermal expansion coefficient and good wear resistance. However, during the production and processing of silicon carbide, a large amount of flue gas is often generated. The flue gas has a high temperature and complex composition. If it is directly discharged, it will pollute the environment.

[0003] The existing technology has the following problems:

[0004] Existing flue gas treatment devices, such as spray towers, when spraying flue gas, the spray water mixes with the flue gas and then flows directly out of the bottom of the spray tower through a pipe. The particles in the flue gas and the spray liquid mix and flow out together. When recycled again, the nozzle in the spray tower is worn and the spray effect is affected. In addition, impurities will be precipitated at the bottom during the flue gas treatment process. After precipitation, it is inconvenient for users to clean the precipitated impurities. After long-term use, it will cause blockage and cannot be removed. During the cleaning process, it will cause inconvenience to the user and affect the user's use.

[0005] To this end, we proposed a silicon carbide high-temperature flue gas treatment device to solve the above-mentioned drawbacks. Utility Model Content

A high-temperature flue gas treatment device for silicon carbide is proposed.
