Integral methane biological desulfurizer

Abstract

The invention discloses an integral methane biological desulfurizer. The desulfurizer comprises a simple substance sulphur settling area I, a methane spraying liquid regeneration area II and a biological packing area III. The simple substance sulphur settling area is provided with an inverted conical settling chamber and a sulphur exhaust pipe; the methane spraying liquid regeneration area is provided with a disk aerator, a dissolved oxygen probe, a triphase separator, a gas collection chamber, a gas-guide pipe, a ring-shaped liquid level regulating tank, a methane inlet pipe and a disk gas-distributing device; and the biological packing area is provided with a biological packing layer, a disk spray thrower and a methane recovery pipe. The device has the follow advantages that culture of desulfurized bacteria and methane desulfuration are integrated into a whole device which has simple structure, simple and convenient processing and convenient promotion and application; the triphase separator of the methane spraying liquid regeneration area removes the potential safety hazard that explosion is prone to occurring when metahne and oxygen are mixed and realizes safe methane biological desulfuration; and the dissolved oxygen probe is used for controlling aeration amount and adopting the ring-shaped liquid level regulating tank to supplement nutrient solution to strengthen growth and metabolism of desulfurized bacteria, thus efficient methane biological desulfuration can be realized and the sulphur simple substance can be recovered.

Description

technical field [0001] The invention relates to an integrated biogas desulfurization device, which is suitable for biogas desulfurization projects. Background technique [0002] Biogas is a kind of renewable energy, and people pay more and more attention to it in the current energy shortage situation. Making full use of biogas energy can alleviate the pressure brought about by my country's energy shortage. Biogas is a flammable mixed gas, generally containing methane, carbon dioxide, and a small amount of ammonia, hydrogen and carbon monoxide, etc. Biogas made from different raw materials often contains different contents of hydrogen sulfide (H 2 S). h 2 S is a highly toxic and harmful gas. It has a strong corrosive effect on pipelines, instruments and equipment. Leaking in the air will pollute the atmosphere and endanger human health. Therefore, in order to protect human health and prolong the service life of equipment, effective measures must be taken for biogas desulf...

AI Technical Summary

Problems solved by technology

At present, domestic desulfurization technology is relatively mature, and there are many desulfurization methods and desulfurization processes, but generally speaking, there are the following disadvantages: dry desulfurization efficiency is not high, desulfurization agent regeneration is difficult, sulfur capacity is relatively low, and it is mainly suitable for fine desulfurization; The wet desulfurization process has large processing capacity, high desulfurization efficiency, and continuous operation, but the investment and operation costs are also high, which is unaffordable for general users of biogas utilization

At present, the defects in these two aspects have not been effectively solved, which hinders the promotion and application of biogas biological desulfurization technology.
