Description
Technical field
The utility model relates to marsh gas preparation device technical field, is specifically related to a kind of biogas recirculation desulfurization preparation facilities.
Background technology
Need in biogas preparation process to carry out desulfurization process, washing method is one of common method of removing hydrogen sulfide in methane, and desulphurization plant is desulfurizing tower, is divided into dry type and wet type two kinds, in dry type desulfurizing, the oxidation rate of iron can not be too fast, otherwise can cause the spontaneous combustion of sulphur simple substance; In wet type desulfurizing, alkali liquor absorption is subject to the impact of the factors such as flow velocity, flow and temperature, hydrogen sulfide and Solubilities of Carbon Dioxide do not reach absolutely, easily NaHS is formed during desulfurization, NaHS at meeting and oxygen reaction, production harmful substance thiosulfate and sulfate, harmful substance is enrichment in absorbing liquid, reduce the absorbability of solution, thus have to regularly discharge doctor solution, cause a large amount of wastes, also bring serious environmental pollution.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of biogas recirculation desulfurization preparation facilities, recycle doctor solution, reduce raw-material waste, reduces environmental pollution.
Biogas recirculation desulfurization preparation facilities described in the utility model, comprise desulfurizing tower, desulfurizing tower is connected with rich solution groove, regeneration tank, foam tank, plate and frame filter press, geosyncline and lean solution groove in turn by pipeline, lean solution groove is by pipeline communication desulfurizing tower, the first circulating pump is provided with between rich solution groove and regeneration tank, be provided with foam pump between foam tank and plate and frame filter press, between lean solution groove and desulfurizing tower, be provided with the second circulating pump; Desulfurizing tower is also connected with compressor, adsorption tower, purified gas surge tank and BNG compressor in turn.
Described geosyncline is provided with desulfurization medicament inlet.
The import and export of described desulfurizing tower is provided with spark arrester.
Operation principle and process:
Biogas enters desulfurizing tower and carries out spray desulfurization, and the biogas after desulfurization enters adsorption tower by compressor, and adsorption tower is to biogas adsorption cleaning, and the biogas after purification enters purified gas surge tank, can use or entrucking sale finally by BNG compressor compresses; Doctor solution in desulfurizing tower is discharged and is entered rich solution groove at the bottom of desulfurizing tower, send into regeneration tank by the first circulating pump to be again oxidized, doctor solution is regenerated in groove, and the doctor solution after regeneration flows into foam tank, and sulphur foam foam pump is sent to plate and frame filter press, filtration is pressed into sulphur recovery, the doctor solution deviate from enters geosyncline, and desulfurization medicament adds further desulfurization in geosyncline, then enters lean solution groove, deliver to desulfurizing tower finally by the second circulating pump, recycle.
The beneficial effect that the utility model is compared with prior art had is:
Biogas recirculation desulfurization preparation facilities can prepare pure biogas for use, the doctor solution reusable edible that sulfur removal technology produces, and can improve desulfurization degree, reclaims sulphur simple substance simultaneously, reduces raw-material waste, reduces environmental pollution.
