Description

Technical Field

[0001] The utility model belongs to the technical field of desulfurization tanks, and in particular relates to a biogas desulfurization tank capable of reducing residual sulfur-containing substances. Background Art

[0002] The production of biogas is accompanied by the generation of a large amount of hydrogen sulfide, which is a toxic gas. It will cause adverse reactions when inhaled by the human body, and in severe cases it can be life-threatening. Hydrogen sulfide itself and the sulfur dioxide, sulfurous acid, and sulfuric acid generated during combustion are toxic to humans. In addition, under aerobic and humid conditions, hydrogen sulfide will corrode pipelines and combustion equipment, so this gas needs to be removed as much as possible.

[0003] A biogas desulfurization tank with a patent announcement number of CN216378086U in the prior art includes a desulfurization tank, wherein a plurality of air-permeable baffles are arranged on the upper part of the interior of the desulfurization tank, a desulfurization chamber three is arranged between two adjacent air-permeable baffles, and a spray mechanism is arranged on the inner top of each desulfurization chamber three; the sulfur-containing substances in the biogas can be filtered through the plurality of desulfurization chambers three, and the connection between the water outlet pipe and the connecting pipe is realized by docking the flange at the connection between the water outlet pipe and the connecting pipe, and the sealing gasket is placed in the flange, so as to realize the connection between the water outlet pipe and the connecting pipe and ensure the sealing performance, and the water pump extracts liquid water through the outlet pipe. The water pipe enters into the connecting pipe, and each desulfurization chamber three is sprayed and cleaned through the spray head on the spray mechanism, so that the sulfur-containing substances in the desulfurization chamber three can be cleaned, avoiding the residual corrosion of the sulfur-containing substances in the desulfurization tank, ensuring the multiple use of the desulfurization chamber three, and the sewage is discharged from the sewage outlet, but there are still the following deficiencies in actual use: From a practical point of view, after the device cleans the desulfurization tank, the cleaned liquid water is directly discharged from the desulfurization tank. Since the sulfur-containing substances are cleaned together during the cleaning process, water pollution occurs. Direct discharge will cause environmental pollution and waste of water resources.

[0004] Therefore, there is a need for a biogas desulfurization tank that can reduce residual sulfur-containing substances to solve the problems of easily causing environmental pollution and increasing resource waste in the prior art. Utility Model Content

[0022] The filtering mechanism 6 facilitates the reuse of the treated water, reduces the pollution to the environment, and improves the environmental friendliness of the device. At the same time, it cooperates with the cleaning mechanism 9 to improve the cleaning efficiency of the desulfurization tank 1.

[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth specifically explaining that the filtering mechanism 6 includes a left connecting pipe 601, which is fixedly connected and communicated with the connecting pipe 5, and a mounting frame 603 is fixedly connected to the right side of the left connecting pipe 601, and a delivery pipe 602 is fixedly connected to the right side of the mounting frame 603 and is connected to the water storage tank 7. A limiting groove 604 is arranged in the mounting frame 603, and a mounting plate 606 is inserted in the limiting groove 604. A sealing plate 607 is fixedly connected to the top of the mounting plate 606, and a filter screen 608 is fixedly installed in the mounting plate 606. A handle 609 is fixedly connected to the top of the sealing plate 607, and the handle 609 is near the four corners and is installed with a rotating pin block 605 on the upper part of the mounting frame 603. The mounting frame 603 is arranged in a box body with an open upper part, and a sealing pad layer is arranged on the surface where the limiting groove 604 and the mounting plate 606 intersect, and the sealing plate 607 is detachably installed in the mounting frame 603 by rotating the pin block 605.

[0024] By setting the filter 608, harmful substances in liquid water can be filtered and purified, and the water can be transported to the water storage tank 7 for reuse. At the same time, by rotating the pin block 605, the filter 608 can be taken out of the installation frame 603 for cleaning, thereby improving its filtering effect, effectively improving resource utilization, and reducing environmental pollution.

[0025] According to the above working process, it can be known that: through the provided filtering mechanism 6, after the sulfur-containing substances in the desulfurization tank 1 are cleaned, the liquid water can be filtered for secondary utilization, while preventing the liquid water from being discharged to affect the environment and reduce resource waste.

[0026] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the cleaning mechanism 9 includes a fixed pipe 901, which is connected to the circulation pipe 8.

When the sulfur-containing substances in the desulfurization tank 1 are cleaned, the pump on the circulation pipe 8 is used to extract liquid through the cleaning mechanism 9 to clean the desulfurization tank 1. At this time, water is respectively cleaned through the three cleaning rings 903 to clean the desulfurization chamber 102 and the partition 103, and the sulfur-containing substances attached thereto are removed. The quality is cleaned to reduce the sulfur content in the desulfurization tank 1. Due to the annular arrangement of the cleaning ring 903, the cleaning efficiency is improved and the cleaning effect is ensured. At the same time, by opening the water outlet valve 4, the liquid is discharged through the connecting pipe 5, and is filtered and purified by the filtering mechanism 6. At this time, the filter screen 608 is arranged to facilitate filtering and purifying harmful substances in the liquid water, and at the same time, the water is transported to the water storage tank 7 for reuse. At the same time, by rotating the pin block 605, the filter screen 608 can be taken out of the installation frame 603 for cleaning, thereby improving its filtering effect.

[0029] In summary: through the provided filtering mechanism 6, after the sulfur-containing substances in the desulfurization tank 1 are cleaned, the liquid water can be filtered for secondary utilization, while preventing the discharge of liquid water to affect the environment and reduce resource waste; through the provided cleaning mechanism 9, the cleaning efficiency in the desulfurization tank 1 is further improved, thereby reducing residual substances and improving the efficiency of the desulfurization tank 1 in desulfurizing biogas.
