Description

Technical Field

[0001] This utility model relates to the technical field of biogas desulfurization spray towers, specifically, to a biogas desulfurization spray tower. Background Technology

[0002] Biogas desulfurization spray towers are important environmental protection equipment, mainly used to remove hydrogen sulfide (H2S) and other sulfides from biogas to improve its purity and usability.

[0003] According to announcement number CN212316052U, a submerged biogas desulfurization device is disclosed, including a spray tower, a regeneration tower, and a sedimentation tank. The spray tower has a packing support plate installed on its inner wall. The packing support plate is sequentially equipped with a bottom layer of packing, a redistributor, and a top layer of packing. A demister is installed above the top layer of packing. A clean biogas pipeline is connected to the top of the spray tower, and a coarse biogas inlet pipeline is connected to the side of the spray tower. A check valve is installed on the coarse biogas inlet pipeline. The regeneration tower has a vent valve connected to its top, a blower installed on its side, and a first circulation pump connected to the side of the regeneration tower. The first circulation pump is connected to the bottom of the spray tower. The sedimentation tank is connected to the bottom of the regeneration tower, and a discharge pipeline is connected to the bottom of the sedimentation tank. This submerged biogas desulfurization device can avoid the generation of secondary waste and has the effects of low power consumption, high desulfurization, and no pollution.

[0004] However, the aforementioned submerged biogas desulfurization device has the following drawbacks:

[0005] Desulfurization is carried out solely through a spray tower, and the desulfurization effect is poor because only spraying technology is used to desulfurize the sulfides inside the tower. After the sulfides are treated by the spray tower, they are directly released into the atmosphere, which means that the sulfides cannot be fully purified, causing air pollution and endangering people's health and safety.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0027] According to an embodiment of the present invention, a biogas desulfurization spray tower is provided.

[0028] Please refer to the instruction manual appendix. Figure 1-5 According to an embodiment of the present invention, a biogas desulfurization spray tower includes a spray tower body 1. The top of the spray tower body 1 is connected to a purification mechanism 3 for tail gas desulfurization via a first pipe 2. The bottom of the spray tower body 1 is connected to an air inlet pipe 4, and a circulation pipe 5 is connected to the air inlet pipe 4. One end of the circulation pipe 5 is connected to the purification mechanism 3. A redistributor 6 is provided at the bottom inner part of the spray tower body 1, and packing 7 is provided above the redistributor 6. A spraying mechanism 8 is fixedly mounted, a filtration mechanism 9 is fixedly mounted above the spraying mechanism 8, and an ionization mechanism 10 is fixedly mounted above the filtration mechanism 9. The spraying mechanism 8 includes a support frame 11, a water storage tank 12 is fixedly mounted at the bottom of the support frame 11, a nozzle 13 is connected to the bottom of the water storage tank 12, and a water pipe 14 is connected to the top of the water storage tank 12. The support frame 11 is fixed to the inner wall of the spraying tower body 1, and the water pipe 14 passes through the spraying tower body 1 and connects to an external water pump and a water tank.

[0029] This allows for physical filtration of the sulfide exhaust gas after spraying treatment in the main body of the spray tower. This multi-stage purification and filtration process greatly improves the desulfurization effect of sulfides, protecting the environment and people's health and safety.

[0030] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, the filtration mechanism 9 is provided with a filter plate 15, a filter cotton plate 16 and an activated carbon adsorption plate 17 arranged sequentially from bottom to top. A first support 18 is movably connected to the lower part of the filtration mechanism 9. The first support 18 is fixedly connected to the inner wall of the spray tower body 1. The ionization mechanism 10 includes a support plate 19. A plurality of ionization tubes 20 are fixed above the support plate 19. A plurality of through holes are opened on the support plate 19. A second support 21 is movably connected to the lower part of the support plate 19. The second support 21 is fixedly connected to the inner wall of the spray tower body 1.

[0031] By setting up a filter mechanism 9, it is convenient to perform physical filtration treatment on the sulfide tail gas again after the spray treatment of the spray tower body 1. By setting up an ionization mechanism 10, it is convenient to perform ionization treatment on the sulfide tail gas again.

[0032] Please refer to the appendix of the specification for another embodiment. Figure 1 As a further embodiment of this utility model, the purification mechanism 3 includes a purification box 22, the top of the purification box 22 is connected to a liquid inlet 23, the liquid inlet 23 is provided with a seal, an exhaust pipe 24 is provided on the circulation pipe 5 near the purification box 22, a first valve 25 is provided on the exhaust pipe 24, and a second valve 26 is provided on the circulation pipe 5.

[0033] By setting up the purification mechanism 3, it is convenient to carry out chemical water washing treatment on the sulfide tail gas after the spray tower treatment, so that the sulfide will undergo chemical reaction to generate organic matter and water, reducing pollution. People can conduct auxiliary tail gas testing at the exhaust pipe 24. If it passes the test, it will be discharged. If it fails the test, it will enter the spray tower body 1 again through the circulation pipe 5 for further treatment until it meets the emission standards. This greatly improves the desulfurization treatment of sulfides and protects the environment and people's health and safety.

[0034] In operation, the sulfide exhaust gas first enters the spray tower body 1 through the inlet pipe 4. An external water pump draws water from the water tank into the storage tank 12, which is then sprayed out through the nozzles 13 for preliminary treatment of the sulfides. Next, the exhaust gas passes through the upper filtration mechanism 9, where it is filtered layer by layer by the filter plate 15, filter cotton plate 16, and activated carbon adsorption plate 17. It then enters the upper ionization mechanism 10, where the ionization tube 20 performs ionization for further treatment. Finally, the exhaust gas enters the purification chamber 22 of the purification mechanism 3 through the first pipe 2. In the purification chamber 22, [the gas is then treated with...]. The agent reacts chemically with the sulfides, causing them to react and produce organic matter and water. Then, the first valve 25 is opened and the second valve 26 is closed. The treated exhaust gas is discharged from the exhaust pipe 24. The exhaust gas can be tested with a detector. If it meets the standards, it can be discharged directly. If it does not meet the standards, the first valve 25 is closed and the second valve 26 is opened. The exhaust gas re-enters the spray tower body 1 through the circulation pipe 5 for further treatment until it meets the standards for discharge. This greatly improves the desulfurization treatment of sulfides and protects the environment and people's health and safety.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
