Embodiment 1

[0023] Example 1. As shown in Fig. 1, the biogas desulfurization device of the present invention is an upright desulfurization tower, the biogas outlet 2, the biogas inlet 1 and the discharge port 7 are respectively arranged at the top, lower waist and bottom of the tower, and the nutrient solution section is formed below the biogas inlet 1. A number of biological fillers 3 with high specific surface are placed in the desulfurization tower (such as commercially available wire mesh fillers, whose specific surface area can reach 250m 2 / m 3 , to increase the amount of biofilm, see Figure 2), the top of the filler is provided with a nutrient solution nozzle 4, the upper end of the delivery pipe 6 with the return pump 5 passes through the desulfurization tower wall and communicates with the nozzle 4, and its lower end passes through the desulfurization tower wall and is submerged into the in the lower nutrient solution. There is an oxygen measuring probe connected to the tempera...

Abstract

The invention relates to a marsh gas biological desulphurization device. The technology issue it needs to resolve is to provide a resolve desulphurization device in manufacture and use, to overcome the disvantage that the oxygen content, temperature and humidity are non-controllable in the device. The marsh gas biological desulphurization device of the invention is a thionizer with a marsh inlet (1) and a marsh outlet (2), in which filling (3) is laid, and a nozzle (4) is mounted above the filling and connected to the feed tube (6) with a reflux pump (5), with the character in that the other nozzle of the said feed tube (6) lies at the nutrient solution segment at the lower of the thionizer; discharge port (7) is mounted on the bottom of the thionizer.

Description

technical field [0001] The invention relates to a gas component separation technology, specifically a biogas desulfurization device, which is suitable for desulfurization of hydrogen sulfide-containing gas biogas or landfill gas produced by anaerobic digestion of biogas projects in livestock and poultry farms, industrial organic wastewater treatment, etc. deal with. Background technique [0002] The biogas produced by anaerobic digestion usually contains hydrogen sulfide gas, and its hydrogen sulfide content is usually between 1000ppm and 3000ppm. Commonly used biogas desulfurization methods include chemical and biological methods. Chemical desulfurization usually adopts the method of dry iron oxide absorption. At room temperature, the biogas passes through the desulfurizer bed, and the H in the biogas 2 S is in contact with active iron oxide to generate iron trisulfide, and then the desulfurizer containing sulfide is in contact with oxygen in the air. When water exists, t...
