Abstract
The invention discloses a methane wet desulphurization device capable of recycling sulphur, which is characterized by comprising a desulfurizing tower, a liquor storage tank, a rich liquor tank, a regeneration tank, a barren liquor tank, and pipelines connected among the tower and the tanks, wherein a flame arrester A is arranged at an inlet pipeline at the bottom of the desulfurizing tower, the liquor storage tank is communicated with the bottom of the desulfurizing tower and is communicated with the rich liquor tank through the pipeline, a flowmeter A is arranged on the pipeline communicating the rich liquor tank with the regeneration tank, and a circulating pump A is arranged on the rich liquor tank; a jet device is arranged in the regeneration tank which is provided with an outlet connected with the barren liquor tank, the pipeline connecting the barren liquor tank with the desulfurizing tower is provided with a flowmeter B, and the barren liquor tank is also provided with a circulating pump B; and an air outlet of the desulfurizing tower is provided with a flame arrester B. The methane wet desulphurization device can improve desulfurization degree, the concentration of sulfuretted hydrogen in methane after desulfuration is lower than 200mg/m3, therefore, a combustion motor in the methane can be well protected, simple substance of sulphur can be recycled, and the device has very good promotional value.
Description
Technical field
The present invention relates to gaseous fuel, specifically relate to a kind of device of biogas wet desulphurization of recyclable sulphur.
Background technology
Washing method is to remove H in the biogas
2One of common method of S.Desulphurization plant is called scrubbing tower, is divided into two kinds of dry type and wet types.
In dry-type desulfurizing tower, desulfurizing agent commonly used is iron oxide, and namely particle diameter is the cast-iron scrap of 0.6～2.4 mm, and desulphurization reaction is as follows:
Desulfurizing agent constantly absorbs the H in the biogas
2S is as the H that absorbs
2When S is in saturation state, H
2The clearance of S will reduce gradually.Should carry out the reducing/regenerating of desulfurizing agent this moment, and regeneration principle is as follows:
Desulfurizing agent through repeatedly absorption and regeneration after, be deposited on most of micropore that wherein sulphur can stop up desulfurizing agent gradually, desulphurizing ability is reduced.When the content of sulphur in the desulfurizing agent is 30%～40%, the desulfurizing agent that namely must more renew.
In wet scrubber tower, generally absorb H with akaline liquid
2S.Biogas enters from the bottom, with the reaction of absorbent counter current contacting, then discharges from cat head.Reaction equation is as follows:
In the actual motion, the oxidation rate of iron can not be too fast in the biogas dry desulfurization, otherwise can cause the spontaneous combustion of sulphur simple substance.Alkali liquor absorption is subject to the impact of the factors such as flow velocity, flow and temperature, H in the wet desulphurization
2S and CO
2Solubility probably do not reach 100%, easily form NaHS during desulfurization, but not Na
2S.NaHS is meeting and oxygen reaction in regenerator, generates harmful substance thiosulfate and sulfate.Harmful substance with enrichment, reduces the absorbability of solution, thereby has to regularly efflux desulphurization circulating liquid in absorption liquid, has wasted a large amount of raw and auxiliary materials, also usually brings secondary environmental pollution.
Summary of the invention
The object of the present invention is to provide a kind of device of biogas wet desulphurization of recyclable sulphur.
The technical scheme that realizes purpose of the present invention is: a kind of device of biogas wet desulphurization of recyclable sulphur, and it comprises desulfurizing tower, reservoir, rich solution groove, regeneration tank, lean solution groove and connects pipeline between them; Wherein the inlet pipeline place of the bottom of desulfurizing tower is provided with spark arrester A, and the bottom of desulfurizing tower is communicated with reservoir, and described reservoir is communicated with the rich solution groove by pipeline, and the pipeline that is communicated with rich solution groove and regeneration tank is provided with flowmeter A, and described rich solution groove is provided with circulating pump A; In the described regeneration tank ejector is arranged, regeneration tank has outlet to connect the lean solution groove, and the pipeline that described lean solution groove connects desulfurizing tower is provided with flowmeter B, also is provided with circulating pump B on the lean solution groove; The gas outlet of described desulfurizing tower is provided with spark arrester B.
Behind the above-mentioned regeneration tank vacuum filter is set, sulfur melting kettle can reclaim elemental sulfur.
Advantage of the present invention: adopt technique desulfurization of the present invention, can improve desulfurization degree, make the hydrogen sulfide in methane concentration after the desulfurization be lower than 200 mg/m
3, the biogas internal combustion engine is had good protective effect, can also reclaim sulphur simple substance simultaneously, have promotional value.
