2S content, thus S content in the tail gas finally reduced, to satisfy new discharge standard, reach the purpose of protection environment.
The utility model content:
The utility model provides a kind of device that reduces hydrogen sulfide emission concentration, and its reasonable in design can reduce H effectively
2The concentration of emission of S, thus final the reduction effluxes the S content in the tail gas, to satisfy new discharge standard, reaches the purpose of protection environment, solved the problem that exists in the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises preceding quench tower; The outlet of preceding quench tower links to each other with the surge tank import through pipeline; The outlet of surge tank links to each other with compressor inlet through pipeline; The outlet of compressor through check valve with after the quench tower import link to each other, the outlet of back quench tower links to each other with the import of adsorption tower through pipeline, the outlet of adsorption tower links to each other with combustion furnace through the control valve group; The chilled water (chw) outlet of preceding quench tower and buffering pot bottom links to each other through the import of pipeline with the chilling water pump respectively; The chilled water (chw) delivery side of pump links to each other with the chilled water (chw) discharge tube with the chilled water (chw) import of preceding quench tower respectively through pipeline, and the chilled water (chw) outlet of back quench tower bottom links to each other through the pipeline of pipeline with chilled water (chw) delivery side of pump place.
Before the outlet of quench tower link to each other with the import of adsorption tower through pipeline, on the pipeline between the import of the outlet of preceding quench tower and adsorption tower, be provided with valve.
The utility model reasonable in design increases surge tank, compressor, back quench tower, with the H that contains of low pressure, low temperature between quench tower and the adsorption tower before being employed in
2S gas is transformed into the H that contains of high temperature, high pressure through compressor
2S gas utilizes the back quench tower that high-temperature gas is lowered the temperature again, promptly is equivalent to increase contain H
2The concentration of S gas, enhancing contains H
2The reaction depth of S gas and poor amine liquid, thus make the H in the gas
2S at utmost is absorbed, and reduces the H in the efflux gas greatly
2S concentration finally reduces the concentration of S in the efflux gas, to satisfy new exhaust emission standard, reaches the purpose of protection environment.

Fig. 1 is the structural representation of the utility model.
Among the figure, 1, preceding quench tower; 2, surge tank; 3, compressor; 4, check valve; 5, back quench tower; 6, adsorption tower; 7, control valve group; 8, chilling water pump; 9, chilled water (chw) discharge tube; 10, valve.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, the utility model is discussed in more detail in conjunction with its accompanying drawing below by the specific embodiment.
Shown in figure; The utility model comprises preceding quench tower 1, and the outlet of preceding quench tower 1 links to each other with surge tank 2 imports through pipeline, and the outlet of surge tank 2 links to each other with compressor 3 imports through pipeline; The outlet of compressor 3 through check valve 4 with after quench tower 5 imports link to each other; The outlet of back quench tower 5 links to each other through the import of pipeline with adsorption tower 6, and the outlet of adsorption tower 6 links to each other with combustion furnace through control valve group 7, and control valve group 7 is used to control the gentle external flow that send of pressure of the utility model treating apparatus; The chilled water (chw) outlet of preceding quench tower 1 and surge tank 2 bottoms links to each other through the import of pipeline with chilling water pump 8 respectively; The outlet of chilling water pump 8 links to each other with chilled water (chw) discharge tube 9 with the chilled water (chw) import of preceding quench tower 1 respectively through pipeline, and the chilled water (chw) outlet of back quench tower 5 bottoms links to each other through the pipeline of pipeline with the exit of chilling water pump 8.
Before the outlet of quench tower 1 link to each other through the import of pipeline with adsorption tower 6, on the pipeline between the import of the outlet of preceding quench tower 1 and adsorption tower 6, be provided with valve 10.When compressor 3 has an accident, can open valve 10, this cross-line pipeline of emergency opening, quench tower 1 ejects the next H that contains before letting
2The low temperature of S, low-pressure gas directly get in the adsorption tower 6 and carry out relevant reaction with poor amine liquid, to guarantee the operate as normal of waste gas treatment equipment.Valve on this cross-line pipeline 10 is handled closed condition at ordinary times.
During work, contain H
2The waste gas of S in the quench tower 1, is lowered the temperature by the cold water that gets in the tower through the chilled water (chw) import before pipeline gets into, and contains H after the cooling
