The workflow of the utility model Integral biological methane desulfurizer is as follows:
Through biogas, import enters thionizer and the packing layer of upwards flowing through to the biogas that contains hydrogen sulfide, fully contact with spray liquid at this, hydrogen sulfide is absorbed and is transferred in liquid phase by these alkaline spray liquid, thereby the hydrogen sulfide in biogas is removed, clean biogas is discharged by the methane outlet at thionizer top, and the spray liquid that has absorbed a large amount of hydrogen sulfide flows into reaction of Salmon-Saxl device certainly by thionizer bottom; In reaction of Salmon-Saxl device due to the effect of thiobacterium, sulfonium ion is changed into elemental sulfur, the mixed solution that contains a large amount of elemental sulfurs pumps into sulphur settling vessel by recycle pump, elemental sulfur natural subsidence in sulphur settling vessel is discharged by sulphur sludge outlet to bottom, and supernatant liquor is back to reaction of Salmon-Saxl device and is transported to thionizer by recycle pump and continues absorbing hydrogen sulphide.Described thionizer is mainly that hydrogen sulfide is gone out to wash out from biogas, and washings is reacted from flowing into reaction of Salmon-Saxl device; Described reaction of Salmon-Saxl device is mainly that sulfonium ion is converted into elemental sulfur, discharges basicity simultaneously, realizes the regeneration of alkali; Described sulphur settling vessel is mainly that elemental sulfur is separated from liquid phase, realizes the recovery of sulphur.
The utility model, due to the design of adverse current filler thionizer, has improved the removal efficiency of hydrogen sulfide in methane greatly; Due to the setting of reaction of Salmon-Saxl device, realize the conversion of sulfonium ion to elemental sulfur, and realized the recovery of alkali, make product not only avoid secondary pollution, can also reclaim its economic worth, due to the regeneration of alkali, greatly saved working cost simultaneously.
Owing to having adopted above technical scheme, the utility model, compared with traditional product, has following beneficial effect:
1), biogas desulfurization efficiency improve, can reach 99%.
2), due to reaction of Salmon-Saxl device energy regenerating alkali, reduced the alkaline consumption of desulfurization, thereby reduced running cost.
3), because product is that elemental sulfur can reclaim, do not produce secondary pollution.
4), due to integrated apparatus, install and easy to operate.
