Description

Technical Field

[0001] The present invention relates to the technical field of gas deodorization, and more specifically, to an efficient double-stage reverse filling type absorption deodorization device. Background Art

[0002] An efficient double-stage reverse filling type absorption deodorization device refers to a device in which a chemical reaction occurs during the absorption process to convert harmful gaseous components into liquid or harmless gases. The most mature and widely used industrial equipment at present is a packed tower, especially a countercurrent packing device. The countercurrent packing device is a purification device in which packing in the shape of a ring, corrugation, hollow sphere, etc. is installed in a cylinder, the absorbent is sprayed downward from the top of the tower onto the packing, and the gas rises along the packing gap, and harmful substances are absorbed through gas-liquid contact.

[0003] However, during the use of the existing efficient double-stage reverse filling type absorption deodorization device, due to the presence of gas particulate impurities in the gas, it may be difficult to remove these particulate impurities through chemical reactions, resulting in the particulate impurities being discharged together with the treated gas, reducing the treatment effect. Moreover, during the treatment process of the traditional efficient double-stage reverse filling type absorption deodorization device, there will be absorbent droplets in the gas, and these droplets will also be discharged together with the treated gas, further reducing the treatment effect.

[0036] The working principle of the present invention:

[0037] First, the gas is introduced into the processing box 1 through the air inlet 2, and then the motor 510 is controlled to work, so that the motor 510 drives the driving cone pulley I 511 fixedly connected to its output shaft to rotate, so that the driving cone pulley I 511 drives the driven cone pulley I 512 engaged therewith to rotate.

[0038] The gas passes through the collection tank 11 under the filtration of the filter screen 52 and reaches the packing 6 at the bottom layer. When the driven cone pulley one 512 rotates, it drives the driving shaft 711 fixedly connected to it to rotate, so that the driving shaft 711 drives the driving pulley one 712 fixedly connected to it to rotate. When the driving pulley one 712 rotates, it drives the driven pulley one 714 to rotate through the belt one 713, so that the driven pulley one 714 drives the driving rod 715 fixedly connected to it to rotate.

When the driving cone pulley two 77 rotates, it drives the fixed shaft 76 fixedly connected to it to rotate, so that the fixed shaft 76 drives the threaded rod two 71 fixedly connected to it to rotate. When the threaded rod two 71 rotates, it drives the threaded seat two 72 threadedly connected to it to move. When the threaded seat two 72 moves, it drives the sprinkler 73 fixedly connected to it to move, so that the sprinkler 73 reciprocally moves along the axis of the threaded rod two 71 under the limiting action of the guide seat two 74 and the guide rod two 75, so as to facilitate uniformly spraying the sulfuric acid solution respectively contained in the inner cavity of the sprinkler 73 on the packing 6.

[0039] The processed gas will enter the bottom demisting barrel 91 through the connecting pipe 10. When the driven cone pulley two 77 rotates, it will drive the linkage rod 918 fixedly connected thereto to rotate, so that the linkage rod 918 drives the driven pulley two 917 fixedly connected thereto to rotate.

When the driven cone pulley three 99 rotates, it will drive the driven cone pulley three 96 engaged therewith to rotate, so that the driven cone pulley three 96 drives the mounting rod 95 fixedly connected thereto to rotate. When the mounting rod 95 rotates, it will drive the vertical rod 97 fixedly connected thereto to rotate, so that the vertical rod 97 drives the connecting plate 98 fixedly connected thereto to rotate. The connecting plate 98 will stir the air in the inner cavity of the demisting barrel 91, so that the air in the inner cavity of the demisting barrel 91 generates a centrifugal force. The sulfuric acid solution droplets entrained in the gas will be thrown on the inner wall of the demisting barrel 91 under the action of the centrifugal force and slide down to the collection box 93 under the action of gravity, thereby preventing the gas from being doped with sulfuric acid solution and causing a reduction in the treatment effect of the next step;

[0040] The gas enters the packing 6 through the connection port 92 and the collection tank 11 above the bottom demisting barrel 91. The sodium hydroxide solution in the upper sprayer 73 will remove the acidic waste gas pollutants in the gas in the same steps, and then remove the sodium hydroxide solution droplets entrained in the gas through the upper demisting assembly 9, and finally be discharged into the atmosphere through the connection port 92 at the top of the upper demisting barrel 91.
