Description

Technical Field

[0001] The utility model belongs to the technical field of biogas purification, and specifically relates to a novel biogas fermentation desulfurization and dehydration device. Background Art

[0002] Biogas contains trace amounts of hydrogen sulfide, which has a slight odor. During the combustion process, hydrogen sulfide will be converted into sulfuric acid, which is extremely corrosive and can damage engines or boilers in a short time. Therefore, it is necessary to remove hydrogen sulfide before combustion. The biogas desulfurization and dehydration system can absorb hydrogen sulfide in biogas, prevent it from corroding biogas combustion equipment and pipelines, and extend its service life. The moisture in biogas and hydrogen sulfide work together to accelerate the corrosion of pipelines, valves, flow meters, etc. Therefore, when desulfurizing biogas, dehydration treatment is required at the same time.

[0003] The prior art discloses a biogas desulfurization and dehydration device with patent announcement number CN217628266U. The above patent can make the biogas evenly distributed inside the desulfurization tower, and evenly contact with the alkali liquid sprayed from the alkali liquid nozzle at the top of the L-shaped branch pipe, thereby increasing the contact area between the biogas and the alkali liquid, and preventing the atomized alkali liquid from entering the biogas connecting pipe. The filter cloth filters the larger alkali droplets, and the alkali-resistant sponge filters the smaller alkali droplets. The filtered alkali droplets flow back to the bottom of the desulfurization tower, but there are still the following deficiencies in actual use: From a practical point of view, the long-term use of the alkali-resistant sponge and filter cloth in the above utility model will cause the atomized alkali liquid to enter the dehydration tank, affecting the dehydration effect. Therefore, the alkali-resistant sponge and filter cloth need to be replaced regularly, but when replacing the above equipment, the tank body needs to be disassembled, which is not easy to operate and reduces work efficiency.

[0004] Therefore, a novel biogas fermentation desulfurization and dehydration device is needed to solve the problem of cumbersome operation when regularly replacing the alkali-resistant sponge and filter cloth in the prior art. Utility Model Content

[0031] By extending the positioning column 210 into the positioning groove 211 , the connection between the desulfurization tank 1 and the moving cylinder 201 can be fixed, so that the desulfurization tank 1 remains in a sealed state without affecting the normal use of the desulfurization tank 1 .

[0032] According to the above working process, it can be known that: through the setting of the closing mechanism 2, the replacement mechanism 5 inside the desulfurization tank 1 can be exposed without disassembling the tank body of the desulfurization tank 1, which is convenient for the staff to replace the replacement mechanism 5, and after the replacement is completed, the desulfurization tank 1 can also be closed without affecting its normal operation.

[0039] This scheme has the following working process: when in use, the biogas first enters the interior of the desulfurization tank 1, and reacts with the alkaline solution for desulfurization.

After the replacement is completed, the pulled top plate 503 is released, and the pressure ring 505 is driven to reset under the elastic action of the spring 504 to fix the filter cloth 507, and then the movable cylinder 201 is pulled up until the slider 202 moves to the top of the slide groove 204, and the threaded rod 209 is rotated in the opposite direction to insert the positioning column 210 into the positioning groove 211, and the connection between the movable cylinder 201 and the desulfurization tank 1 is fixed to ensure the airtightness of the desulfurization tank 1 so that the desulfurization tank 1 can be used normally.
