Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
According to embodiment of the present utility model, provide the de-equipment of hydrogen sulfide essence in a kind of landfill gas.
As shown in Figure 1, surge tank 1 is comprised according to the de-equipment of hydrogen sulfide essence in the landfill gas of the utility model embodiment, steam trap 2, filter 3, desulfurizing tower 4 and blower fan 5, wherein, the air inlet of described surge tank 1 is connected with the gas outlet of landfill gas equipment, the air inlet of described steam trap 2 is connected with the gas outlet of described surge tank 1, the air inlet of described filter 3 is connected with the gas outlet of described steam trap 2, the top air inlet of described desulfurizing tower 4 is connected with the gas outlet of described filter 3, the gas outlet, bottom of described desulfurizing tower 4 is connected with the air inlet of described blower fan 5.
Wherein, the number of described desulfurizing tower 4 is two, and this two desulfurizing towers 4 parallel connection is connected between described filter 3 and described blower fan 5.
Wherein, described two desulfurizing towers 4 are primary desulfurizing tower 401 and desulfurizing tower for subsequent use 402.Further, the pressure in described desulfurizing tower 4 is-15 ~-10kPa.
Wherein, described blower fan 5 is roots blower.Further, the admission pressure scope of described roots blower is-15 ~-10kPa.
During concrete use, raw material landfill gas removes free moisture through the buffering of surge tank 1, steam trap 2 successively, filter 3 enters in desulfurizing tower 4 by the top of desulfurizing tower 4 after removing mechanical admixture, fully contact with the desulfurizing agent in desulfurizing tower 4 and carry out desulfuration operations, landfill gas after desulfurization is discharged from the bottom of desulfurizing tower 4, then enters the entrance of roots blower 5 and after boosting, flows to follow-up equipment use.And when using, above-mentioned desulfurizing tower 4 is arranged in parallel two, one open one standby, switch and use, desulfurizing tower 4 desulfurization or for subsequent use in, in a desulfurizing tower 401 or 402, desulfurizing agent to reach in working sulfur capacity, outlet landfill gas hydrogen sulfide content when exceeding standard, just need to change desulfurizing agent, be switched to another desulfurizing tower 402 or 401 and carry out normal desulfuration operations, and working sulfur capacity can absorb the capacity of sulphur for unit volume desulfurizing agent when guaranteeing technique degree of purification index, exporting sulfur content in landfill gas and exceeding standard for H2S > 15mg/m3.
