Description

Technical Field

[0001] The invention relates to the technical field of tail gas filtration, and in particular to a tail gas comprehensive absorption device. Background Art

[0002] Methane is a non-polar molecule with a regular tetrahedral structure and is the simplest organic substance. As the main component of conventional natural gas, shale gas, combustible ice, etc., methane is a very important carbon-based resource. It is the most important non-CO2 greenhouse gas. In the stratosphere of the atmosphere, methane will be decomposed into water vapor (clouds), thus causing the destruction of the ozone layer.

[0003] However, with the rapid development of industry, purified methane can have a higher value, so many methods for purifying methane have emerged, one of which is to absorb carbon dioxide in methane with alkaline solution. However, when carbon dioxide reacts with alkaline solution, calcium carbonate precipitation is often generated. Therefore, when the absorption device works for a long time, personnel often need to stop the device to clean up the precipitation, which is very inconvenient for personnel to use.

[0042] In summary, when the exhaust gas comprehensive absorption device is used, the gas will enter the reaction chamber from the air inlet pipe, thereby reacting with the alkaline solution in the reaction chamber (wherein a drain pipe connected to the reaction chamber is provided in the middle of the outer peripheral surface of the reaction absorption kettle 1, so that personnel can discharge the liquid in the reaction chamber, and an inlet pipe connected to the reaction chamber is provided at the upper part of the outer peripheral surface of the reaction absorption kettle 1, so that personnel can pour alkaline solution into the reaction chamber through the inlet pipe). When the gas is discharged into the alkaline solution, the carbon dioxide contained in the gas will react with the solution, thereby absorbing the carbon dioxide in the gas. However, when the carbon dioxide reacts with the solution, calcium carbonate precipitation will be generated, so it is necessary to filter the solution to promote the solution to continuously absorb the carbon dioxide in the gas better. At the same time, the absorbed gas will be discharged from the outlet pipe (2);

[0043] When the liquid in the filter bin mixed with the precipitate enters the filter barrel 29 through the first liquid inlet, the second liquid inlet and the third liquid inlet in sequence, the two second liquid inlets are arranged so that the liquid can enter only two filter spaces, and then be filtered through the two filter screens 17, and then the precipitate will be left behind by the filter screens 17, and the liquid will enter the auxiliary connecting pipe 43 from the water suction port 38, and then enter the converging annular barrel 25 through the auxiliary connecting pipe 43, and then enter the water pump through the water suction pipe 24, and finally discharge the liquid back to the reaction bin through the water pump and the water spray pipe 12;

[0044] When the water pump is working, it can generate suction in the two filter screens 17 to transport the liquid to the top of the reaction chamber. However, when the precipitation in the two filter spaces and the precipitation on the adsorption filter screen 17 continue to increase, a negative pressure will be formed in the internal space of the filter screen 17, so that the middle part of the filter screen 17 will be tightened, thereby pulling the filter support plate 16 to move downward. At the same time, due to the setting of the auxiliary driving cylinder 15, the auxiliary driving cylinder 15 will move downward with the filter support plate 16 while prompting the filter support plate 16 to rotate with it. When the filter support plate 16 moves downward and rotates, it will prompt the auxiliary driving ring 19 to move downward with it, and the auxiliary driving ring 19 will rotate with it. The auxiliary driving ring 19 will prompt the second support cylinder 7 and the third support rod 22 to move downward with it, wherein the second support cylinder 7 will cause the tension spring 9 to be stretched through the auxiliary ring 8 when it moves downward, and the downward movement of the third support rod 22 will move downward with the toggle block 35 through the driven ring plate 34. At the same time, because the first driving rod 3 will always rotate with the toggle block 35 through the driven ring plate 34, when the toggle block 35 is connected to a limit driving bayonet without the ejection hemispherical head 30, it will prompt the filter barrel 29 to rotate with its toggle block 35. At the same time, through the setting of the two magnets 33, the toggle block 35 can be more stably clamped. The filter barrel 29 is connected to the limit drive bayonet, but when the filter barrel 29 rotates to ninety degrees with the toggle block 35, the toggle block 35 will be pushed up by the ejector hemispherical head 30 (because when the filter barrel 29 just starts to rotate, the ejector hemispherical head 30 will be squeezed to move downward, and when the toggle block 35 rotates with the filter barrel 29 to ninety degrees, the reset ejector hemispherical head 30 will push the toggle block 35 out of the limit drive bayonet), so that the toggle block 35 is separated from the limit drive bayonet, and the filter barrel 29 will rotate with the two auxiliary connecting pipes 43 to the bottom of the next group of two opposite filter screens 17, so as to continue to filter the liquid in the reaction chamber, and the other two filter screens At this time, the bottom of 17 is just opposite to the leakage outlet 39, so that the sediment in the two filter spaces will fall downward from the leakage outlet 39 to the inner bottom surface of the filter bin, and then flow out through the discharge pipe (the discharge pipe is arranged at the bottom end of the outer peripheral surface of the reaction absorption kettle 1, and the discharge pipe is connected with the filter bin). When the filter barrel 29 rotates, the filter barrel 29 will also rotate with the second auxiliary guide plate 11, so that the two second liquid inlets will be temporarily closed, and then the top ends of the two second liquid inlets are connected with the other two first liquid inlets, and the bottom ends of the two second liquid inlets are connected with the third liquid inlet, so as to change the liquid in the reaction bin to enter the other two filter spaces.
