DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1-Figure 7An environmentally friendly absorption tower shown in the figure includes an absorption tower 100, and a filter assembly 200 and a spray pipeline 300 assembled in the absorption tower 100. A drain pipe 400 and an exhaust gas inlet pipe 500 are respectively provided at the bottom of the left and right sides of the absorption tower 100. The height at which the axis of the drain pipe 400 is located is lower than the height at which the axis of the exhaust gas inlet pipe 500 is located. There are several filter assemblies 200, and the filter assembly 200 includes a mesh box 210 with a cone structure and a mounting baffle 220 fixedly mounted on an outer side wall of the mesh box 210.

There are several spray pipelines 300, and several spray pipelines 300 are respectively arranged below several filter assemblies 200.

[0022] Based on the above-mentioned structural setting, specifically, during the working process, the exhaust gas enters the absorption tower 100 from the exhaust gas inlet pipe 500, the exhaust gas flows upward, and the spray pipeline 300 sprays the absorption liquid downward. The absorption liquid interacts with the exhaust gas, and the exhaust gas is then further absorbed and filtered in conjunction with the filter component 200. After passing through the filter component 200, the exhaust gas that has completed the absorption treatment is output through the exhaust pipe 130 for subsequent treatment. The filter component 200 is installed on the absorption tower 100 with a retractable assembly structure. When the operator replaces the filler, it is necessary to first remove the filter component 200. 0 is disassembled and pulled out, and then the operator unscrews the threaded cover 250 on the discharge port 240 to discharge the filler. After the filler is discharged, the operator tightens the threaded cover 250 on the discharge port 240 to fill the new replacement filler. The environmentally friendly absorption tower improves the traditional drawer structure for containing fillers and uses a mesh box 210 with a cone structure as a substitute. When discharging, with the help of the discharge port 240, the operator can realize convenient unloading after unscrewing the threaded cover 250, which greatly improves the efficiency of filling replacement.

Specifically, the bottom box 110, the unit box 120, and the exhaust pipe 130 are assembled by stacking flanges from bottom to top in sequence, and when the adjacent structures are assembled by flanges, the enclosure 140 located at the lower structure extends to the bottom of the upper structure, and the enclosure 140 covers and shields the joint between the two adjacent structures, ensuring the sealing of the assembly of the two adjacent structures.

[0024] Furthermore, the bottom box 110 includes a base 1110 and a first shell 1120 which are assembled with lower and upper flanges, and a conical flow guide structure 1130 is provided on the top of the base 1110. Specifically, the first shell 1120 is flange-assembled on the base 1110, and the flow guide structure 1130 is embedded in the first shell 1120 so that the absorption liquid accumulated at the bottom of the bottom box 110 flows from the middle to the circumference and is finally discharged from the drain pipe 400.

[0025] Furthermore, the unit box 120 is provided in a plurality, and the unit box 120 includes a second shell 1210, the front of the second shell 1210 is provided with an adapting hole 1220 for the mesh box 210 to be movably inserted, the left and right inner sides of the second shell 1210 are fixedly connected with angle irons 1230 for supporting the mesh box 210, and a window 1240 is provided on one side of the second shell 1210. Specifically, the unit box 120 cooperates with the filter assembly 200 to form a prefabricated independent component, and according to the specific requirements of the actual installation, the operator can stack and assemble the plurality of unit boxes 120 from bottom to top by flange, so as to cooperate with different types of fillers to achieve different filtering requirements.

[0026] Furthermore, a sealing gasket 260 is glued to the inner side of the mounting baffle 220. Specifically, the sealing gasket 260 is glued to the inner side of the mounting baffle 220 and is enclosed and sleeved on the periphery of one side of the mesh box 210.
