Description

Novel desulfurizer

Technical Field

The utility model belongs to the technical field of marsh gas desulfurization, concretely relates to novel desulfurizer.

Background

When organic wastes in agriculture, animal husbandry, industry and life are subjected to anaerobic fermentation to produce biogas, sulfur-containing compounds are converted into H₂S, so that the generated biogas contains H₂And (4) S gas. It is a very corrosive compound, so it can be used for treating H in marsh gas₂The removal of S is a key link for methane utilization. Generally, H in biogas₂The mass concentration of S is 1-12 g m-3, and because the S is greatly influenced by fermentation raw materials and a fermentation process, when the content of protein or sulfate in the raw materials is high, H in the fermented biogas₂The S mass concentration is greater. The environmental protection standard of China is strictly regulated, and when the marsh gas is used for generating electricity, H in the marsh gas₂The S content should not exceed 200-300 mg of m-3; if biogas is incorporated into a gas pipeline or as vehicle fuel, then H₂S is less than or equal to 15mg of "m-3 [1]. It can be seen that H is contained in the biogas₂Since the mass concentration of S is far above a predetermined value, it is necessary to remove S as much as possible in industrial or civil gas.

The existing biogas desulfurization mode can roughly adopt three methods, namely physical, chemical and biological, according to physicochemical properties. However, the biogas desulfurization method can be divided into two major categories, direct desulfurization and indirect desulfurization, according to the principle of the desulfurization method. The direct desulfurization is to remove H in the methane₂Directly separating and removing S gas; indirect desulfurization refers to a specific method adopted in the process of generating the biogas to reduce or inhibit H₂And (4) generation of S gas. The direct biogas desulfurization method can be divided into a wet method and a dry method according to different principles.

The dry desulfurization technique is to utilize oxygen to remove H₂The method is a biogas desulfurization method for oxidizing S gas into elemental sulfur or sulfur oxide. The common method is ferric oxide dry desulfurization method, activated carbon method, membrane separation method, etc., and H is suitable₂The gas with lower S concentration is widely applied in industry due to simple structure and mature desulphurization technology. The traditional dry desulfurization method adopts a pot type desulfurization method, the size of equipment is limited due to limited stack height of a desulfurizer, and some large-scale desulfurization projects must be placed indoorsOld-fashioned digester equipment is higher can not place in indoorly, and equipment transportation and installation are also comparatively inconvenient simultaneously.
