[0003] According to a desulfurization tower with good desulfurization effect with authorization announcement number CN211562475U, the patent is a known prior art, and although the patent has the advantages of simple structure, good demisting effect and high desulfurization efficiency, the technical solution of the patent still has the following defects in actual use: in the patent, since the diameter of the air outlet at the top of the tower body is small, and the gas-liquid separation layer, the multi-layer flow-through sieve plate and the demisting layer are all fixedly connected to the inside of the tower body, and are difficult to disassemble, clean or replace, when the desulfurization tower is used for a long time, a large amount of impurities will adhere to the surface of the gas-liquid separation layer, the multi-layer flow-through sieve plate and the demisting layer, which will lead to poor desulfurization effect of subsequent exhaust gas. For this reason, we propose a desulfurization tower with good desulfurization effect. Utility Model Content

[0021] In this embodiment, when the air inlet valve is opened, the exhaust gas can be input into the interior of the desulfurization tower body 1 along the air inlet pipe 3, and at the same time, the liquid inlet valve is opened, so that the desulfurization liquid flows into the interior of the infusion sleeve 41 along the liquid inlet pipe 42, and the desulfurization liquid can be sprayed out from the nozzle 43, so that the desulfurization liquid can fully contact with the exhaust gas, which is convenient for preliminary desulfurization treatment of the exhaust gas. When the particulate impurities in the exhaust gas contact with the desulfurization liquid, they will fall due to the increase of their own weight and gather at the bottom of the inner cavity of the desulfurization tower body 1 with the desulfurization liquid. After the exhaust gas desulfurization is completed, the sewage valve is opened so that the sewage at the bottom of the inner cavity of the desulfurization tower body 1 can be discharged along the sewage funnel 12.

[0022] See also Figure 2, the inside of the desulfurization tower body 1 is respectively provided with a filter screen 5 and an activated carbon plate 6 from bottom to top, the filter screen 5 and the activated carbon plate 6 are parallel to each other, and the filter screen 5 and the activated carbon plate 6 are movably sleeved inside the desulfurization tower body 1, the top of the filter screen 5 is fixedly connected with a mounting sleeve 7, the internal thread sleeve of the mounting sleeve 7 is sleeved with a screw 8, the screw 8 runs through the middle of the activated carbon plate 6, and the external thread sleeve of the screw 8 is sleeved with a fixing ring 9, the top of the screw 8 is fixedly connected with a mounting plate 10, the fixing ring 9 and the activated carbon plate 6 are in close contact, and the mounting plate 10 and the desulfurization tower body 1 are fixedly connected with screws;

[0023] In this embodiment, after the exhaust gas is sprayed, the exhaust gas will continue to flow upward and pass through the filter 5 and the activated carbon plate 6, so as to filter the residual particulate impurities in the exhaust gas. The activated carbon plate 6 can also dry the exhaust gas and absorb the odor in the exhaust gas, thereby further desulfurizing the exhaust gas. When there are too many impurities adhering to the surface of the filter 5 and the activated carbon plate 6, the bolts are rotated to open the tower cover 2, and the screws are rotated again to loosen the mounting plate 10 and the desulfurization tower body 1, and the mounting plate 10 is lifted upward to promote the filter. 5 and the activated carbon plate 6 are moved out from the interior of the desulfurization tower body 1, and then the filter screen 5 is rotated to separate the bottom ends of the mounting sleeve 7 and the screw 8, so that the filter screen 5 can be removed. Secondly, the fixing ring 9 at the bottom of the activated carbon plate 6 is rotated to separate it from the bottom end of the screw 8, and the activated carbon plate 6 is pulled vertically downward to remove the activated carbon plate 6 from the bottom end of the screw 8, so that the filter screen 5 and the activated carbon plate 6 can be removed conveniently for disassembly, cleaning or replacement, thereby ensuring the filtering effect of the filter screen 5 and the activated carbon plate 6, thereby improving the desulfurization effect of the exhaust gas.

[0025] In this embodiment, when the vacuum pump 113 is started, negative pressure is generated inside the exhaust pipe 111, and suction is generated at the exhaust hood 112 due to the negative pressure. At this time, the exhaust gas purified by the activated carbon plate 6 is sucked from the exhaust hood 112 due to the suction and discharged along the exhaust pipe 111.

[0026] The working principle and use process of the utility model are as follows: first, the air inlet valve is opened so that the exhaust gas can be input into the interior of the desulfurization tower body 1 along the air inlet pipe 3, and at the same time, the liquid inlet valve is opened so that the desulfurization liquid flows into the interior of the infusion sleeve 41 along the liquid inlet pipe 42, and the desulfurization liquid can be sprayed out from the nozzle 43, so that the desulfurization liquid is fully in contact with the exhaust gas, which is convenient for preliminary desulfurization treatment of the exhaust gas;
