at the same time, the tail gas generated in incineration will continuously enter the alkaline washing tank 41 from the air guide hole arranged on the rotating shaft 31, at this time, through the meshing effect between the second bevel gear 44 and the first bevel gear 43, the linkage shaft 42 will rotate along with the rotating shaft 31, and at the same time, the alkaline washing blade 45 will also rotate (it is to be noted that the surface height of the sodium hydroxide solution in the alkaline washing tank 41 should be located at the rotating shaft 31), accompanied by the alkaline washing blade 45, the solution stained on the side wall thereof will be thrown out, and when the alkaline washing blade 45 is in the sodium hydroxide solution, the solution will enter the alkaline washing blade 45 from the liquid inlet hole 451, a part of the solution will be stored in the alkaline washing blade 45 along with the rotation lifting of the alkaline washing blade 45, when the alkaline washing blade 45 rotates to the top of the alkaline washing tank 41, due to the magnetic phase-repellent plates 454 at the top of the inner cavity of the sealing plate 454, the spring expansion rod will be extruded, the liquid outlet hole 452 will be opened, the alkaline washing blade 45 will be thrown out under the action of the rotating centrifugal force, the blade 45 will be made to be in the inner part of the blade, and the aqueous film will be cut off by the second water film, and the exhaust gas can be further burnt out by the second water film, the environmental protection is further, and the environmental protection is realized, and the environmental protection is realized.
It should be noted that, specific model specifications of the motor need to be determined by selecting a model according to actual specifications of the device, and a specific model selection calculation method adopts the prior art in the field, so detailed description is omitted.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
