[0007] An air inlet end is provided on the side of the cylinder, and the air inlet end is located between two adjacent adsorption plates. A supplementary air flow enters the cylinder through the air supply port and flows toward the exhaust end. When passing through the adsorption plate, it mixes with the exhaust gas entering through the air inlet end and then flows out from the exhaust end.

[0008] Furthermore, at least two of the air supply ports are respectively arranged on both sides of the cylinder.

[0009] Furthermore, the axis of the air inlet end is arranged perpendicularly to the axis of the cylinder.

[0010] Furthermore, the air supplement port is used to be connected to an air compressor, and the air compressor provides supplementary air flow into the air supplement port.

[0011] Furthermore, the air supply port is located below the air inlet end.

[0012] Compared with the related art, the utility model proposes a waste gas purification equipment for graphite production, which has the beneficial effect of: by arranging a gas supplement port at the lower end of the cylinder, the supplementary air flow enters into the cylinder through the gas supplement port and is transported upward, the exhaust gas enters into the cylinder through the air inlet end, and the exhaust gas is adsorbed and purified by the adsorption plate, and the exhaust gas is pushed by the supplementary air flow to make it more efficiently contact with the adsorption plate and achieve purification treatment, the exhaust gas enters into the area between adjacent adsorption plates laterally, and contacts with the adsorption plates for purification treatment, the supplementary air flow flows from bottom to top and pushes the exhaust gas to move upward, so that the exhaust gas contacts with the next adsorption plate and completes the purification treatment, thereby the purification equipment can improve the contact performance between the exhaust gas and the adsorption plate and improve the purification efficiency of the exhaust gas from graphite production.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] See also Figure 1-2 As shown, the utility model provides an exhaust gas purification device for graphite production, which includes a cylinder 11 and an adsorption plate 12.

[0017] An air supply port 21 is provided at the bottom of the cylinder 11, and at least two air supply ports 21 are respectively provided on both sides of the cylinder 11. The air supply port 21 is located below the air inlet end 22. The air supply port 21 is used to be connected to an air compressor, and the air compressor provides a supplementary air flow into the air supply port 21. An exhaust end 23 is provided at the top of the cylinder 11, and the air flow enters into the cylinder 11 through the air supply port 21 and flows out from the exhaust end 23. By providing the air supply port 21 at the lower end of the cylinder 11, the supplementary air flow enters into the cylinder 11 through the air supply port 21 and is transported upward.

[0018] A plurality of adsorption plates 12 are arranged inside the cylinder 11, and the plurality of adsorption plates 12 are arranged at intervals in the height direction. Adsorption materials are arranged inside the adsorption plates 12 to adsorb harmful impurities such as tar in the graphite production waste gas.

[0019] An air inlet end 22 is provided on the side of the cylinder body, and the axis of the air inlet end 22 is arranged perpendicularly to the axis of the cylinder body 11. The air inlet end 22 is located between two adjacent adsorption plates 12. The supplementary air flow enters the cylinder body 11 through the air supply port 21 and flows toward the exhaust end 23. When passing through the adsorption plate 12, it mixes with the exhaust gas entering through the air inlet end 22 and then flows out from the exhaust end 23.

[0020] The waste gas enters into the cylinder 11 through the air inlet end 22, and is adsorbed and purified by the adsorption plate 12. Driven by the supplementary airflow, the waste gas is more efficiently in contact with the adsorption plate 12 and purified. The waste gas enters the area between adjacent adsorption plates 12 laterally and contacts with the adsorption plates 12 for purification. The supplementary airflow flows from bottom to top and pushes the waste gas upward, so that the waste gas contacts with the next adsorption plate 12 and completes the purification, thereby improving the purification efficiency of waste gas from graphite production.
