Desulfurization device

Abstract

The invention relates to a desulfurization device, and belongs to the technical field of desulfurization. The desulfurization device comprises a reactor, a filter, a first liquid storage tank, a lifting pump, a water injection device and communicating pipelines. The communicating pipelines comprise a first communicating pipeline, a second communicating pipeline, a third communicating pipeline and a fourth communicating pipeline, the lifting pump is located in the first liquid storage tank, the filter is communicated with a bottom outlet of the reactor through the first communicating pipeline, and the first liquid storage tank is communicated with a bottom outlet of the filter through the second communicating pipeline; and the lifting pump is communicated with a top inlet of the reactor through a third communication pipeline; the water injection device is communicated with the filter through a fourth communication pipeline. Filter cloth washing water in the filter is stored in the first liquid storage tank, the lifting pump injects the filter cloth washing water stored in the first liquid storage tank into the reactor, sufficient water in the reactor is guaranteed, reaction can be completed, the filter cloth washing water is recycled, resource waste is avoided, and cost is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of desulfurization, in particular to a desulfurization device. Background technique [0002] Hydrogen sulfide (chemical formula: H 2 S). Sulfur elements in natural gas, acid gas or tail gas can be used to produce sulfur. If these sulfur-containing gases are discharged directly, it will not only cause waste of resources, but also cause pollution to the environment. The sulfur-containing gas needs to be desulfurized, and the liquid-phase oxidation desulfurization process is a commonly used desulfurization process in related technologies. [0003] The desulfurization device of the liquid phase oxidation desulfurization process includes: a reactor, a feeding device and a filter. In the liquid-phase oxidative desulfurization process, the sulfur-containing gas and oxygen are first sent into the reactor, and then the complex iron solution is injected into the reactor to make the high-valent iron ions (F...

AI Technical Summary

Problems solved by technology

[0004] In related technologies, during the process of filtering sulfur by the filter cloth, sulfur particles may be attached to the filter cloth, which will affect the filtering effect of the filter cloth, and the filter cloth needs to be washed

However, the remaining filter cloth washing water after washing the filter cloth contains a large amount of chemical components. If it is directly discharged, it will pollute the environment, and the filter cloth washing water needs to be treated, which increases the cost.
