when the tail gas can damage the steady state of the tail gas under the action of vibration and low temperature, the tail gas can continuously separate out electrolyte solids outwards in the vibration process, the electrolyte solids fall to the bottom of the cooling barrel 61 after being separated out, and when the electrolyte solids fall between the first filter screen 611 and the second filter screen 612 through the first filter screen 611, the rolling balls 613 are driven to roll back and forth in the shaking process of the cooling barrel 61, so that the electrolyte solids are ground, the particle diameter of the electrolyte solids is reduced, the electrolyte solids can be conveniently recycled by workers, and great convenience is brought to the workers; when the cooling barrel 61 is shaking, the push rod 614 reciprocates between the first filter screen 611 and the second filter screen 612 under the action of the elastic rope, the push rod 614 generates thrust to the rolling ball 613 when sliding reciprocally, the rolling ball 613 is pushed to roll back and forth, and the rolling effect of the rolling ball 613 is enhanced, so that the whole using effect and the practicability of the tail gas treatment device 3 are improved.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
