[0007] Preferably, the gas dispersion mechanism includes drive motor installed on the upper end of the shell, the output shaft of the drive motor extends to the inside of the shell, and is fixedly connected with rotating cylinder.

[0008] Preferably, multiple air holes are arranged on the outer side of the rotating cylinder, and one end of the intake pipe located in the shell extends to the inside of the rotating cylinder.

[0009] Preferably, the inner space of the collecting groove is communicated with a discharge pipe.

[0010] Preferably, an electromagnetic valve is installed in the inner space of the discharge pipe and the connecting port.

[0011] Preferably, an air pump is installed on the left side of the collecting groove, a check valve is installed at the air outlet end of the air pump, and the air outlet end of the air pump extends into the inner top space of the collecting groove.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1. The exhaust gas enters the rotating cylinder through the air inlet pipe and is uniformly discharged through multiple air holes. At the same time, the start of the driving motor makes the rotating cylinder rotate, further enhancing the dispersion effect of the exhaust gas. This design ensures the full contact of the exhaust gas with the denitration catalyst liquid, thereby greatly improving the uniformity and efficiency of the exhaust gas treatment.

[0014] 2. The liquid pump pressurizes the denitration catalyst liquid into multiple hollow rings and uniformly sprays it through the atomizing nozzle. This atomizing treatment method not only increases the contact area of the catalyst with the exhaust gas, but also improves the utilization efficiency of the catalyst and reduces the treatment cost.

[0015] 3. The waste liquid generated during the treatment process falls into the collecting groove through the connecting port, avoiding the risk of pollution caused by direct discharge of the waste liquid to the external environment. When it is necessary to discharge the waste liquid, the electromagnetic valve on the connecting port is closed and the electromagnetic valve on the discharge pipe is opened, and the air pump is started to blow air into the collecting groove. The waste liquid can be safely and non-pollutingly discharged to the outside. This design ensures that the waste liquid does not come into contact with the external environment during the entire treatment process, effectively preventing the potential impact of the treatment liquid on the surrounding environment.

[0016] 4. The discharge process of the waste liquid and the exhaust gas treatment process are independent of each other and do not interfere with each other. This means that while the waste liquid is being discharged, the exhaust gas treatment device can still operate normally, ensuring the continuity and stability of the exhaust gas treatment.
