Description

Technical Field

[0001] The utility model relates to the field of biogas biological desulfurization, and in particular to a multi-stage spraying biogas biological desulfurization device. Background Art

[0002] After anaerobic treatment, wastewater and solid waste containing organic matter produce a large amount of biogas. Due to the action of sulfate-reducing bacteria, a large amount of hydrogen sulfide is also produced. Since hydrogen sulfide is toxic and corrosive, it limits the comprehensive utilization of biogas. Therefore, the biogas needs to be desulfurized through a desulfurization tower.

[0003] The prior art with patent publication (announcement) number CN217773788U discloses a multi-stage spray-type biogas biological desulfurization device, comprising: a spray assembly, including a tower body, an air inlet connected to the tower body, an air outlet connected to the top of the tower body, a liquid discharge port connected to the lower end of the side wall of the tower body, a spray pipe arranged on the inner wall of the tower body, two spray pipes are provided and the two spray pipes are connected together, an injection pipe connected to the spray pipe and a water pipe inserted in the injection pipe, the outer end of the water pipe is connected to a water pump, the water pump is connected to a water tank, and the water pump is connected to a water tank filled with a reaction liquid.

[0004] The above-mentioned patent document discloses a multi-stage spray-type biogas biological desulfurization device. Although it can solve the problem that the reactants of the contact reaction between the absorption liquid and the biogas will be deposited in the lower layer of the bottom of the spray tower, the reactants are easily accumulated on the bottom layer after long-term use, which will cause corrosion to the bottom layer over time. However, the disadvantage is that the reactants accumulated on the bottom are directly cleaned by a brush, and the solid reactants are likely to cause blockage of the drain port, which is inconvenient to use.

[0005] Therefore, we made improvements to this problem and proposed a multi-stage spray type biogas biological desulfurization device. Utility Model Content

[0042] In this embodiment: by arranging a spring 507 inside the chute 505, the wiping rod 506 inside the chute 505 can be supported by the elastic force of the spring 507 itself, so that the wiping rod 506 contacts the inner wall of the bottom of the tank body 1. When the mounting rod 504 rotates, the wiping rod 506 is driven to rotate, thereby cleaning the reactants accumulated at the bottom of the tank body 1 and discharging them from the drain pipe 8.

[0043] like Figure 1 - Figure 5 As shown, based on the above embodiment, in order to enable the multi-stage spray-type biogas biological desulfurization device to filter the reactants produced by the reaction, this embodiment provides the following design:

[0044] As a preferred embodiment, the filtering mechanism 9 includes a fixed cylinder 901, and mounting holes 902 are provided on the upper and lower surfaces of the fixed cylinder 901. The fixed cylinder 901 is connected to the sewage pipe 8 through the mounting holes 902 on the upper and lower sides, and a filter net 903 is fixedly installed inside the lower mounting hole 902.

[0045] In this embodiment: by opening mounting holes 902 on the upper and lower surfaces of the fixed cylinder 901, it is convenient to connect the fixed cylinder 901 to the sewage pipe 8, and the reactants produced by the reaction can be filtered through the filter net 903 inside the bottom mounting hole 902, and the reaction liquid will flow out through the filter net 903.

[0046] As a preferred embodiment, a second motor 904 is fixedly mounted on one side surface of the fixed cylinder 901, and the output end of the second motor 904 is fixedly connected to a rotating shaft 905, and a spiral blade 906 is fixedly mounted on the outer surface of the rotating shaft 905, and the spiral blade 906 is in contact with the inner wall of the fixed cylinder 901 and the filter screen 903.

[0048] Specifically, the working principle of this solution is:

[0049] During use, the biogas that needs to be desulfurized will enter the tank body 1 through the air inlet pipe 2. At the same time, the reaction liquid is discharged into the water inlet pipe 401, so that the reaction liquid enters the first annular pipe 402, and is discharged into the second annular pipe 403 through the connecting pipe 405. The reaction liquid will be sprayed out from the nozzle 404 fixedly installed on the lower surface of the first annular pipe 402 and the second annular pipe 403. By setting the first annular pipe 402 and the second annular pipe 403, the reaction liquid can be sprayed more evenly, and the biogas can be better desulfurized. The desulfurized biogas will be discharged from the exhaust pipe 3.

[0050] During the reaction process, some solid reactants will be produced and fall to the bottom of the tank body 1. The first motor 501 is started to drive the rotating rod 502 at the output end to rotate, and drive the connecting rod 503 and the surface mounting rod 504 to rotate at the bottom of the tank body 1. The wiping rod 506 inside the slide groove 505 can be supported by the elastic force of the spring 507 itself, so that the wiping rod 506 contacts the inner wall of the bottom of the tank body 1. When the mounting rod 504 rotates, it drives the wiping rod 506 to rotate, cleans the reactants accumulated at the bottom of the tank body 1, and discharges them from the drain pipe 8.

[0051] When the reactants pass through the fixed cylinder 901, the reactants produced by the reaction can be filtered through the filter screen 903 inside the bottom mounting hole 902, and the reaction liquid will flow out through the filter screen 903. The second motor 904 is started to drive the rotating shaft 905 at the output end to rotate, and drives the spiral blades 906 on the surface to rotate. The filtered solid reactants can be transported by the spiral blades 906 until they are transported out of the fixed cylinder 901.
