Abstract
The utility model discloses a dry method desulfurization system, which comprises a desulfurization tower. The desulfurization tower is communicated with a reaction tank communicated with a regenerating tower, the regenerating tower is respectively communicated with the desulfurization tower and a foam separation tank, and the foam separation tank is communicated with the reaction tank. The dry method desulfurization system is characterized in that a clean gas produced by the desulfurization tower is communicated with a benzene washing tower communicated with a coke filter, and the coke filter is communicated with the dry method desulfurization tower. The dry method desulfurization system adopts a wet desulphurization technology and a dry desulphurization method, the two types of desulphurization methods are combined, the wet desulphurization is used to remove most H2S in coal gas, and then the dry desulphurization is used to remove the H2S in coal gas, thereby achieving higher desulphurization cleanliness. The dry method desulfurization system has the advantages of online adjustment through the wet desulphurization and high efficiency through the dry desulphurization. According to above treatment scheme, content of H2S in the coal gas purified by subsequent processes under normal working conditions is decreased to 50mg/Nm3, and final emission concentration of sulfur dioxide is not higher than 100mg/Nm3, thereby meeting requirements of national environment production.
Description
Technical field
The utility model relates to a kind of dry method desulfuration system of coal tar factory.
Background technology
The coke oven gas desulfurization method that adopts is wet desulphurization at present, as alkali source, adopts 888 desulfurization catalysts with yellow soda ash, and coke-oven gas is carried out desulfurization.888 desulfurization catalyst major ingredient are phthalocyanine cobalt organometallicss, and its radical has stronger ability to take oxygen, thereby reduce the activation energy of chemical reaction, accelerate chemical reaction velocity.But since defective of this method self and operation factors influence, the sweetening effectiveness instability.H after the desulfurization
2S content is at 200～400mg/m
3Fluctuation can not be satisfied the requirement of national regulation.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of at the good dry method desulfuration system of sweetening effectiveness.
The utility model is achieved through the following technical solutions:
A kind of dry method desulfuration system, comprise thionizer, thionizer is communicated with reactive tank, reactive tank is communicated with regenerator column, regenerator column is communicated with thionizer and foam separator respectively, and foam separator is communicated with reactive tank, the purified gas that described thionizer produces with wash the benzene tower and be communicated with, wash the benzene tower and be communicated with coke filter, coke filter is communicated with the dry desulfurization tower.
Described dry desulfurization tower is three.
Described three dry desulfurization towers are communicated with for series connection.
Described three dry desulfurization towers are in parallel the connection.
The utility model has the advantages that: adopted the method for wet desulphurization and dry desulfurization, two kinds of sulfur methods are combined application, utilized wet desulphurization earlier with the most of H in the coal gas
2S removes, and then, utilizes dry desulfurization to the H in the coal gas again
2S carries out essence and takes off, thereby reaches higher desulfurization cleanliness.So both utilize the advantage that wet desulphurization can online adjustment, utilized the high advantage of dry desulfurization efficient again.According to above resolution, subsequent handling purifies H in the coal gas under the nominal situation
2The content of S is reduced to 50mg/Nm
3, final sulfur dioxide emissioning concentration is not higher than 100mg/Nm
3, reach the requirement of national environmental protection.
Description of drawings
Fig. 1 is embodiment 1 structural representation;
Fig. 2 is embodiment 2 structural representations.
Embodiment
Embodiment 1: a kind of as shown in Figure 1 dry method desulfuration system, comprise thionizer 6, thionizer 6 is communicated with reactive tank 9, reactive tank 9 is communicated with regenerator column 7, and regenerator column 7 is communicated with thionizer 6 and foam separator 8 respectively, and foam separator 8 is communicated with reactive tank 9, the purified gas that described thionizer 6 produces with wash benzene tower 1 and be communicated with, wash benzene tower 1 and be communicated with coke filter 2, coke filter 2 is communicated with dry desulfurization tower 3,4,5, and three dry desulfurization towers 3,4,5 are communicated with for series connection.
Be to improve the utilising efficiency of sweetening agent, 3 smart thionizers of this device can parallel connection also can serial operation.Purify the H of coal gas when the outlet of the 1st tower
2S content surpasses 30mg/Nm
3The time, with the 2nd, 3 group of serial operation, up to the outlet H of the 1st tower
2S concentration thinks that the sweetening agent of the 1st tower lost efficacy during near unstripped gas concentration, and the 1st tower is excised out flow process, only with the operation of the 2nd, 3 towers, and the 1st tower thionizer replacing sweetening agent.Switch to then the 2nd, 3 towers preceding the 1st tower the back serial operation.In like manner, the sweetening agent in can online replacing the 2nd, 3 tower thionizers.
Embodiment 2: the structure of present embodiment is substantially the same manner as Example 1 as shown in Figure 2, and its difference is that described three dry desulfurization towers 3,4,5 are communicated with in parallel.
Claims (4)
1. dry method desulfuration system, comprise thionizer, thionizer is communicated with reactive tank, reactive tank is communicated with regenerator column, regenerator column is communicated with thionizer and foam separator respectively, and foam separator is communicated with reactive tank, it is characterized in that: the purified gas that described thionizer produces with wash the benzene tower and be communicated with, wash the benzene tower and be communicated with coke filter, coke filter is communicated with the dry desulfurization tower.
2. dry method desulfuration system according to claim 1 is characterized in that: described dry desulfurization tower is three.
