Description
Technical field
The utility model relates to gas desulphurisation plant technical field, is specifically related to a kind of biogas recirculation desulfurizer.
Background technology
Washing method is one of common method of removing hydrogen sulfide in methane, and sweetener is thionizer, and be 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 objectionable impurities thiosulphate and vitriol, objectionable impurities is enrichment in absorption liquid, reduce the receptivity 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 desulfurizer, recycle doctor solution, reduce raw-material waste, reduces environmental pollution.
Biogas recirculation desulfurizer described in the utility model, comprise thionizer, thionizer is connected with rich solution groove, regeneration tank, foam chute, plate-and-frame filter press, geosyncline and lean solution groove in turn by pipeline, lean solution groove is by pipeline communication thionizer, the first recycle pump is provided with between rich solution groove and regeneration tank, be provided with foam pump between foam chute and plate-and-frame filter press, be provided with the second recycle pump between lean solution groove and thionizer, geosyncline is provided with desulfurization medicament inlet.
The import and export of described thionizer is provided with spark arrester.
Principle of work and process:
Biogas enters thionizer and carries out spray desulfurization, doctor solution is discharged and is entered rich solution groove at the bottom of thionizer, then sends into regeneration tank oxidation by the first recycle pump, and doctor solution is regenerated in groove, doctor solution after regeneration flows into foam chute, sulphur foam foam pump is sent to plate-and-frame filter press, and filter and be pressed into sulphur recovery, the doctor solution deviate from enters geosyncline, desulfurization medicament adds further desulfurization in geosyncline, then enter lean solution groove, deliver to thionizer finally by the second recycle pump, recycle.
The beneficial effect that the utility model is compared with prior art had is:
Biogas recirculation desulfurizer recycle doctor solution, can improve desulfurization degree, reclaims sulphur simple substance simultaneously, reduces raw-material waste, reduces environmental pollution.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, thionizer; 2, rich solution groove; 3, the first recycle pump; 4, regeneration tank; 5, foam chute; 6, foam pump; 7, plate-and-frame filter press; 8, geosyncline; 9, lean solution groove; 10, the second recycle pump.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, biogas recirculation desulfurizer comprises thionizer 1, thionizer 1 is connected with rich solution groove 2, regeneration tank 4, foam chute 5, plate-and-frame filter press 7, geosyncline 8 and lean solution groove 9 in turn by pipeline, lean solution groove 9 is by pipeline communication thionizer 1, the first recycle pump 3 is provided with between rich solution groove 2 and regeneration tank 4, be provided with foam pump 6 between foam chute 5 and plate-and-frame filter press 7, be provided with the second recycle pump 10 between lean solution groove 9 and thionizer 1, geosyncline 8 is provided with desulfurization medicament inlet.
The import and export of thionizer 1 is provided with spark arrester.
During work, biogas is sent into thionizer 1 and is carried out spray desulfurization, doctor solution is discharged and is entered rich solution groove 2 at the bottom of tower, send into regeneration tank 4 by the first recycle pump 3 to be again oxidized, doctor solution is regenerated in groove, doctor solution after regeneration flows into foam chute 5, sulphur foam foam pump 6 is sent to plate-and-frame filter press 7, filtration is pressed into sulphur recovery, the doctor solution deviate from enters geosyncline 8, and desulfurization medicament adds further desulfurization in geosyncline 8, then enters lean solution groove 9, deliver to thionizer 1 finally by the second recycle pump 10, recycle.
