Description

Technical Field

[0001] This utility model belongs to the field of acid gas treatment technology, and in particular relates to an acid gas adsorption and filtration device. Background Technology

[0002] Acidic gases, when dissolved in water, react to form acids, including sulfur oxides, nitrogen oxides, and other compounds. These gases are present in extremely small amounts in the atmosphere, and in some areas are even undetectable. The presence of acidic gases increases corrosion of pipelines and equipment, affecting their service life. During the cryogenic separation of natural gas, CO2 may form dry ice, clogging pipelines and equipment; natural gas with a high H2S content produces an unpleasant odor when burned, and the resulting SO2 and other compounds pollute the environment; in catalytic processing, sulfur-containing hydrocarbons can poison the catalyst. Therefore, the removal of acidic gases is one of the main tasks of natural gas purification.

[0003] In the prior art, acid gas adsorption and filtration devices generally use chemical or physical methods for treatment. The internal structure of the device is relatively simple and lacks a guiding structure, which easily leads to the acid gas staying inside the device for too short a time, resulting in poor filtration effect. Therefore, an acid gas adsorption and filtration device is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an acidic gas adsorption and filtration device to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an acidic gas adsorption and filtration device, comprising a filter box and an alkaline solution storage box. The alkaline solution storage box is fixedly installed on the upper surface of the filter box. A first water collecting plate is fixedly installed on one surface inside the filter box, and a second water collecting plate is fixedly installed on the other surface inside the filter box. The second water collecting plate is positioned above the first water collecting plate. Several spray heads are installed on the lower surfaces of both the second and first water collecting plates. A first connecting pipe is installed on the upper surface of the first water collecting plate, and a second connecting pipe is installed on the upper surface of the second water collecting plate. This facilitates the blocking of acidic gas inside the filter box after it is absorbed, preventing the acidic gas from rising directly but instead causing it to rise indirectly below the first and second water collecting plates. This increases the residence time of the acidic gas inside the filter box, allowing it to react fully with the alkaline solution sprayed by the spray heads, thereby improving the filtration effect of the device.

[0007] Furthermore, the upper end of the spray head is connected to the interior of the first water collecting plate and the second water collecting plate, respectively, and the upper ends of the first connecting pipe and the second connecting pipe both penetrate the upper surface of the filter box.

[0008] Furthermore, the upper ends of the first and second connecting pipes are connected to the interior of the alkaline solution storage tank, and two water pumps are fixedly installed on the bottom surface inside the alkaline solution storage tank.

[0009] Furthermore, the two pump output ends are respectively connected to the upper ends of the first connecting pipe and the second connecting pipe, and a replenishment pipe is installed on the upper surface of the alkaline solution storage tank, which is connected to the inside of the alkaline solution storage tank.

[0010] Furthermore, a suction pipe is installed on one surface of the filter box, one end of the suction pipe is connected to the inside of the filter box, the suction pipe is located below the first water collection plate, a first exhaust fan is installed on the periphery of the suction pipe, and a semi-permeable membrane is installed inside the other end of the suction pipe.

[0011] Furthermore, an installation groove is provided on another surface of the filter box. The installation groove is located above the second water collection plate. Activated carbon is movably installed inside the installation groove to improve the desulfurization effect on acidic gases and further improve the filtration effect of the device. A connecting gas pipe is screwed to one surface of the installation groove, and a second exhaust fan is installed at one end of the connecting gas pipe.

[0012] Furthermore, a drain pipe is installed on the lower surface of the filter box, the upper end of the drain pipe is connected to the inside of the filter box, a control valve is installed on the periphery of the drain pipe, and a controller is installed on the front surface of the filter box.

[0013] Furthermore, the controller is electrically connected to the water pump, the first exhaust fan, the second exhaust fan, and the control valve, respectively, and support rods are welded to the periphery of the lower surface of the filter box.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the structure of the first water collection plate, the second water collection plate, and the spray head, facilitates the blocking of acidic gases inside the filter box after the acidic gases are drawn in. This prevents the acidic gases from rising directly, but instead causes them to rise in a circuitous manner under the first and second water collection plates, increasing the residence time of the acidic gases inside the filter box. This allows the alkaline solution sprayed by the spray head to react fully, thereby improving the filtration effect of the device.

[0016] 2. The novel semi-permeable membrane and activated carbon structure of this utility model pre-treat and finish-up the acidic gas, improve the desulfurization effect of the acidic gas, and further improve the filtration effect of the device.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
