Bio-gas hydrogen sulfide removal device by using ion exchange fiber Pall ring for bio-gas purification

Abstract

The present invention relates to a bio-gas hydrogen sulfide removal device which can continuously remove hydrogen sulfide in bio-gas. The bio-gas hydrogen sulfide removal device adopts ion exchange fiber Pall ring for bio-gas purification. The Pall ring is filled in a net drum cylinder. The Pall ring is provided with ion-exchange fiber. When the drum rotates, the Pall ring precipitates in a regeneration liquid for ion exchange. Through the internal friction shock of the Pall ring, under the condition of without an external additional device, the regenerated chloride is removed efficiently, so that the hydrogen sulfide scavenging capacity is maintained at the maximum, and the use amount of the regeneration liquid is reduced. In addition, hydrogen sulfide from bio-gas is removed, so that the damage of hydrogen sulfide in the process of using bio-gas is minimized. Corrosion for power equipments and boilers can be prevented by using bio-gas as a fuel.

Description

technical field [0001] The present invention relates to a hydrogen sulfide removal device contained in biogas, and in more detail relates to the use of ion-exchange fiber Pall rings for biogas purification Hydrogen sulfide scavenging device for a tumbling cylinder filled with Pall rings provided with ions for the purpose of scavenging hydrogen sulfide from gas obtained by refining treatment of biogas used as thermoelectric fuel By exchanging fibers, the frictional impact generated by the rotation of the drum effectively removes the chloride generated after regeneration without external additional devices, so as to maintain the highest hydrogen sulfide removal capacity and reduce the usage of regeneration fluid , can continuously remove hydrogen sulfide, and at the same time minimize the harm caused by the generation of sulfide in the process of biogas utilization, and the structure is simple, making maintenance and management simple and easy. Background technique [0002] ...

AI Technical Summary

Problems solved by technology

[0010] That is, regardless of the type of hydrogen sulfide removal device in the past, there is a problem that its structure is complicated, it is inconvenient to manufacture and use, and there is a problem that the hydrogen sulfide removal efficiency gradually decreases with the passage of time.

[0011] For this reason, attempts have been made in the corresponding fields to develop hydrogen sulfide removal devices that are simple in structure, easy to manufacture and use, and can continuously maintain hydrogen sulfide removal efficiency, but so far have not been able to obtain satisfactory results
