[0041] In this embodiment, it should be noted that the double-shaft motor 173, the electromagnetic valve one 185, and the electromagnetic valve two 21 can be purchased on the market. Their circuit connection mode and control mode belong to mature technology in the field, which is fully disclosed and described herein, and therefore will not be described again.

[0042] Through the above structure, the working principle of the high-efficiency self-cleaning spray cyclone purification device provided by the present application is as follows:

[0043] During the process of the exhaust gas containing pollutants being transported into the exhaust gas purification cylinder 1 through the exhaust gas inlet pipe 3, the double-shaft motor 173 is started to rotate, the double-shaft motor 173 drives the two connecting shafts 174 to rotate, the two connecting shafts 174 drive the hollow cross beam 8 and the cyclone plate 4 to rotate respectively, and the rotating directions of the hollow cross beam 8 and the cyclone plate 4 are opposite. When the exhaust gas passes through the cyclone plate 4, the exhaust gas is forced to generate strong cyclone movement due to the guide vanes 43. The cyclone movement makes the exhaust gas form a spiral upward airflow track in the exhaust gas purification cylinder 1, greatly increases the residence time of the exhaust gas in the exhaust gas purification cylinder 1, and also increases the surface area of the exhaust gas contacting the subsequent purification medium;

[0044] At the same time, the absorption liquid is controlled to enter through the absorption liquid conveying pipe 11, flow into the hollow cross beam 8 through the rotating pipe joint 10 and the hollow vertical pipe 7, and be sprayed out by the plurality of inclined water mist sprayers 9 to fully mix with the exhaust gas. In this process, the pollutants in the exhaust gas react with the absorption liquid physically or chemically, are adsorbed or neutralized by the absorption liquid, so as to realize the removal of the pollutants in the exhaust gas. Through the rotation of the hollow cross beam 8, the range of the atomized spray of the absorption liquid can be increased, so that the misty absorption liquid is fully diffused and fully contacts with the exhaust gas, thereby the purification effect and efficiency of the exhaust gas can be improved. Due to the opposite rotating directions of the cyclone plate 4 and the hollow cross beam 8, the rotating airflow guided by the cyclone plate 4 and the absorption liquid sprayed out by the water mist sprayer 9 will form a mutual intersecting and colliding state, which greatly increases the contact area between the gas and the liquid, the pollutants in the gas can more fully react with or be adsorbed by the absorbent or purification component in the absorption liquid, and the misty absorption liquid can more fully capture and combine the tiny particles in the exhaust gas, reduce the content of particulate matters in the exhaust gas, and further improve the purification effect and efficiency of the exhaust gas;

[0045] The gas after the spray purification contains a certain amount of water mist. When the gas rises to the demister 12 position, the demister 12 separates the water mist from the purified gas by interception and adsorption, so that the gas discharged from the purified gas discharge pipe 13 is dry and clean, which can effectively avoid secondary pollution to the environment;

[0046] With the increase of the equipment running time, the surface of the cyclone plate 4 will gradually accumulate impurities and dirt, when the cyclone plate 4 needs to be cleaned, open the electromagnetic valve 185, the water flows into the U-shaped pipe 183 from the water inlet pipe 184, because the two ends of the U-shaped pipe 183 are connected with two hollow horizontal shafts 181 respectively, the water flow will uniformly enter the two hollow horizontal shafts 181, then the water flow is sprayed out from the multiple water spray heads 182 fixed on the hollow horizontal shaft 181 and uniformly distributed, the upper and lower sides of the cyclone plate 4 are washed all-round, the distribution and spray angle of the water spray head 182 ensure that every part of the cyclone plate 4 in the rotating process can be washed by the water flow, so as to effectively remove the impurities and dirt attached to the surface of the cyclone plate 4, and make it return to a good working state;

[0047] By opening the electromagnetic valve two 21 regularly or as needed, the sewage and impurities generated in the purification process can be discharged outside the exhaust gas purification cylinder 1 through the sewage pipe 20.

[0048] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
