Embodiment 1

[0020] The biogas desulfurization device in this example is as figure 1 and figure 2 As shown, the side of the water washing tank 2 is provided with an air intake pipeline 1, and the top of the water washing tank 2 is provided with a water washing tank gas pipeline 3. The water washing tank gas pipeline 3 communicates with the bottom of the biological desulfurization tank 4, and the top of the biological desulfurization tank 4 A biological desulfurization tank gas pipeline 5 is provided, and the biological desulfurization tank gas pipeline 5 communicates with the bottom of the fine desulfurization tank 6, and the top of the fine desulfurization tank 6 is provided with a gas outlet pipeline 7, and two or more fine desulfurization tanks 6 are arranged in parallel; The water washing tank 2 and the biological desulfurization tank 4 are provided with a circulating spray device 9 ; the water washing tank 2 is provided with a multi-layer water spray packing layer 8 , and the biologi...

Embodiment 2

[0025] The biogas desulfurization device in this example is as figure 1 and image 3 As shown, except that in the biological desulfurization tank 4, a filler fluidization section 23 is arranged above the biofilm-adhered filler layer 10, and a desulfurization liquid distributor 20 is arranged above the filler fluidization section 23, the rest is the same as that of the first embodiment. .

[0026] In this example, when the total gas flow rate increases and exceeds the critical flow rate of the biofilm-attached filler, the biofilm-attached filler layer 10 in the biological desulfurization tank 4 can be fluidized, and a huge active biofilm surface is released, The hydrogen sulfide and the desulfurization liquid rich in dissolved oxygen have sufficient contact mass transfer and biochemical reaction on the active biofilm of the filler, so that the hydrogen sulfide is removed from the biogas. The biogas flow rate can be effectively increased, and the processing efficiency per unit...

Embodiment 3

[0028] The biogas desulfurization device in this example is as figure 1 and Figure 4 As shown, the desulfurization liquid distributor 20 in the biological desulfurization tank 4 is a spiral tube that runs through the biofilm-attached filler layer 10 and the filler fluidization zone 23, and different spray pipe openings are set at different heights Compare. All the other are with embodiment two.

[0029]In this example, according to the change of the dissolved oxygen concentration gradient in the liquid phase when spraying is not performed, different spray pipe opening ratios are set at different heights of the desulfurization liquid distributor 20, so that the desulfurization liquid spray volume can be adjusted according to the dissolved oxygen concentration gradient. The change of the oxygen concentration gradient is timely and effectively supplemented, so as to achieve the purpose of eliminating the dissolved oxygen concentration gradient. It can also make the desulfuriz...

Abstract

The invention discloses a biogas desulfurization device, belonging to the technical field of biogas production. The biogas desulfurization device is formed by sequentially connecting a washing tank (2), a biological desulfurization tank (4) and a fine desulfurization tank (6) with one another, wherein a gas inlet pipeline (1) is arranged on the washing tank (2); a washing tank gas pipeline (3) is arranged on the top of the washing tank and is communicated with the bottom of the biological desulfurization tank (4); a biological desulfurization tank gas pipeline (5) is arranged on the top of the biological desulfurization tank (4) and is communicated with the bottom of the fine desulfurization tank (6); a gas outlet pipeline (7) is arranged on the top of the fine desulfurization tank (6); the washing tank (2) and the biological desulfurization tank (4) are provided with cycle spraying devices (9); multiple layers of spraying packing layers (8) are arranged in the washing tank (2); and a biological film adhesion packing layer (10) is arranged in the biological desulfurization tank (4). The biogas desulfurization device provided by the invention is high in operating reliability and low in operating cost, the usage amount of chemical desulfurizing agents is small, and the removal rate of hydrogen sulfide is high.

Description

technical field [0001] The invention belongs to the technical field of biogas production, and in particular relates to a biogas desulfurization device. Background technique [0002] In the prior art, there is a fine desulfurization device in the biogas desulfurization device. The fine desulfurization device adopts the chemical desulfurization method. Whether the chemical desulfurization method is dry or wet, a large amount of chemical desulfurization agent is consumed, which not only increases the operating cost of the biogas project, but also Create large quantities of chemical pollutants that are difficult to treat. There are also a small number of water washing methods, which can effectively remove solid particles, ammonia gas and other water-soluble gas impurities, reduce interfering substances for the fine desulfurization device, and can also remove a small part of hydrogen sulfide gas. There is also a biological desulfurization method that uses microbial biochemical r...
