Abstract
The utility model relates to a device for removing hydrogen sulfide in biogas by a dry method. The device comprises a tank body, wherein a biogas outlet and a biogas inlet tube are respectively arranged on one sides at the top and bottom of the tank body. A biogas distributor is arranged at the bottom of the tank body. The biogas distributor corresponds to the biogas inlet tube. At least three-stage desulfurization layers are installed in the tank between the biogas outlet and the biogas distributor. The device provided by the utility model has the advantages that the desulfurization efficiency is improved while the cost is lowered greatly; the filling height can be effectively reduced through grading; and hydrogen sulfide in biogas can be removed over 90% to meet the demand on gas quality of the biogas users.
Description
Technical field
The utility model belongs to the marsh gas purifying process field, specifically is that a kind of hydrogen sulfide in methane removes device.
Background technology
Usually no matter contain hydrogen sulfide gas in the biogas that the reaction of biogas microbiological anaerobic produces, be to be directly used in burning or marsh gas power generation, all must carry out necessary desulfurization to biogas.
Dry desulfurization is because of simple in structure, along with development of science and technology, new and effective desulfurizing agent emerges in an endless stream, new and effective desulfurizing agent has the desulfurization precision height, reaction speed is fast, and the work Sulfur capacity is big, intensity and water-tolerant, characteristics such as the Applicable temperature scope is wide, so dry desulfurization takes off the field in essence and still is in consequence.
Dry-desulphurizer mainly contains active carbon, and iron oxide (α-Fe2O3 and γ-Fe2O3), zinc oxide, molecular sieve etc.The iron oxide aboundresources, cheap and easy to get, be to use maximum biogas desulfurization methods, reaction equation at present
,
When the iron sulfide content in the desulfurizing agent reaches 30% when above, the obvious variation of desulfurized effect, desulfurizing agent can not continue to use, and needs regeneration, and regenerative response is:
,
The zinc oxide adsorbent desulfurization precision is higher, and the speed of absorption H2S is fast, reacts to be:
Summary of the invention
The purpose of this utility model provides the dry removal device of the hydrogen sulfide in methane that a kind of desulfurized effect is good, safe and reliable, operating cost is low.The technical solution of the utility model is: a kind of device of dry removal hydrogen sulfide in methane, comprise tank body, be respectively arranged with biogas venthole and biogas air inlet pipe at the top of described tank body and a side of bottom, bottom in the described tank body is provided with the biogas distributor, this biogas distributor is corresponding with the biogas air inlet pipe, and at least three grades of desulfurization layers are installed in the tank body between biogas venthole and biogas distributor.
Spacing distance between described each grade desulfurization layer includes desulfurizing agent and filter, and described filter is installed in the bottom of desulfurizing agent, and the upper end of described desulfurizing agent and the tank body of bottom are provided with stuffing hole and dumping pit.
The bottom of described biogas distributor is provided with blow-off pipe, described blow-off pipe and exterior.
Described biogas venthole place is equipped with the baffle plate of giving vent to anger.
The utility model has the advantages that: improve desulfuration efficiency greatly and reduce cost; Can effectively reduce loading height by classification; Can reach the biogas user to the requirement of makings with the hydrogen sulfide stripping in the biogas more than 90%.
Description of drawings
Fig. 1 is agent structure schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of device of dry removal hydrogen sulfide in methane, comprise tank body 10, be respectively arranged with biogas venthole 2 and biogas air inlet pipe 1 at the top of described tank body 10 and a side of bottom, bottom in the described tank body 1 is provided with biogas distributor 4, this biogas distributor 4 is corresponding with biogas air inlet pipe 1, and at least three grades of desulfurization layers are installed in the tank body 10 between biogas venthole 2 and biogas distributor 4.
Spacing distance between described each grade desulfurization layer includes desulfurizing agent 7 and filter 5, and described filter 5 is installed in the bottom of desulfurizing agent 7, and the upper end of described desulfurizing agent 7 and the tank body of bottom are provided with stuffing hole 8 and dumping pit 6.
The bottom of described biogas distributor 4 is provided with blow-off pipe 3, described blow-off pipe 3 and exterior.
Described biogas venthole 2 places are equipped with the baffle plate 9 of giving vent to anger.
Operation principle of the present utility model is: biogas enters tank body by biogas air inlet pipe 1, by biogas distributor 4 biogas is evenly distributed, with guarantee biogas contact with desulfurizing agent evenly, abundant, owing to contain small amount of impurities and steam in the biogas, meeting condensation when contacting with the biogas distributor, the part dust that produces when in addition, loading desulfurizing agent also can be discharged by sewage draining exit.Biogas by one-level, secondary, three grades of desulfurization layers and after desulfurizing agent fully contacts, can be discharged dust-filtering and finish sweetening process through outlet damper successively at last by the tank deck escape pipe.
