Abstract
The utility model discloses a desulfurizing device for low-concentration acidic gases containing H2S (hydrogen sulfide), and relates to a desulfuration purification device for acidic gases generated during the production processes of petrochemical engineering, coal chemical engineering and the like. The desulfurizing device comprises an acidic gas preheater, a reactor, a sulfur condenser and a sulfur separator, which are connected in sequence; and the sulfur separator is connected with a liquid sulfur recoverer and a washing tower respectively. The desulfurizing device can desulfurize low-concentration acidic gases containing the H2S with the content of 0.5 percent to 2 percent, and ensures the discharged sulfide to be live up to the standard without any wet desulphurization, and the content of the discharged H2S content is smaller than and equal to 100 mg/Nm<3>, and the content of SO2 is smaller than and equal to 50 mg/Nm<3>, sulfur is recycled, and remarkable economic, social and environmental benefits can be brought.
Description
Technical field
The utility model relates to the desulfurization purifier of the sour gas that produces in the production processes such as petrochemical industry, Coal Chemical Industry, is specifically related to a kind of low concentration H that contains
2The desulfurizer of S sour gas.
Background technology
Strengthening day by day and the raising of environmental protection standard of Along with people's environmental consciousness adopts high-effect, high benefit, sulfur recovery technology that investment cost is low that sour gas is handled, and reaches environmental emission standard, has very important realistic meaning.
At present for the processing of sour gas, adopt the SCOT technology that grows up on the Claus sulfur recovery technical foundation, SuperClaus technology, Clinsulf technology, Sulfreen technology, MCRC technology etc. mostly, these technology investment costs are high, import H
2The S content requirement is high, complex process.
For H
2The processing of the low concentration sour gas of S content 0.5～2%, none production safety environmental protection still, the desulfurization purifier that technology is succinct, simple to operate flexibly, cost of investment is few, operating cost is low.
Summary of the invention
The purpose of the utility model provides a kind of low concentration H that contains
2The desulfurizer of S sour gas is to reach production safety environmental protection, technology is succinct, simple to operate, cost of investment is few, operating cost is low purpose.
The utility model is realized through following technical scheme:
A kind of low concentration H that contains
2The desulfurizer of S sour gas comprises the sour gas preheater, reactor, sulfur condenser, the sulphur separator that connect successively, and the sulphur separator is connected with scrubbing tower with the molten sulfur recover respectively.During work, H
2S content is that the sour gas of 0.5～2% (V%) mixes with air through after the heating of sour gas preheater; Send into reactor; Carry out condensation through getting into sulfur condenser behind the catalyst bed reaction; Get into sulphur content after the condensation and separate from device, molten sulfur is sent into the molten sulfur recover and is stored or solidify, and gas send smoke stack emission after scrubbing tower washing cooling is up to standard.
The utility model is compared with existing system, has the following advantages:
The utility model can be to H
2The low concentration sour gas of S content 0.5～2% carries out desulfurization to be handled, and guarantees that without any need for wet desulphurization outlet sulfide is up to standard, outlet H
2S content≤100mg/Nm
3, SO
2≤50mg/Nm
3, to the sulfur recovery utilization, bring remarkable economic efficiency, and bring social benefit, the environmental benefit of highly significant.
