Abstract
The utility model discloses a semi-water gas desulphurization device, belongs to the technical field of petrochemical industries and coal chemical industries, and relates to desulphurization devices. The semi-water gas desulphurization device comprises a static decoking device, a Roots blower, a cooling tower, a packed tower, a cleaning tower and a gas-liquid separator, wherein the static decoking device, the Roots blower, the cooling tower, the packed tower, the cleaning tower and the gas-liquid separator are connected in sequence, an intersection distributor is arranged in the packed tower, an empty tower, a desulphurization pump, a regenerative pump and a regenerative groove are sequentially arranged between the cooling tower and the packed tower, and a nozzle is arranged in the empty tower. The semi-water gas desulphurization device can effectively solve the problem of blockage in desulphurization tower and has the advantages of being safe and environment-friendly, stable in operation, easy to operate, and little in investment cost. In addition, the semi-water gas desulphurization device has important practical significance on technology improvement on fields such as the ceramic industries and the coal chemical industries.
Description
Technical field
The utility model belongs to petrochemical complex, technical field of coal chemical industry, relates to desulfurizer, is specifically related to a kind of semiwater gas desulphurizing device.
Background technology
At present, the semiwater gas desulphurizing of national many small nitrogen fertilizer business all adopts wet desulphurization, its sweetening agent multiselect tannin extract, 888, PDS, DDS etc., and all desulfurizers are used packing tower basically entirely, import H
2S is basically at 2000mg/Nm
3About, if H2S is slightly high, system loading strengthens, stifled tower phenomenon is serious, so each enterprise requires extra-high-speed to the hard coal sulphur content of entering factory.
In recent years along with the growing tension of feed coal supply, coal price constantly soaring impels high sulphur coal constantly to enlarge and be widely used in the use of enterprise, and each enterprise is because the stifled tower parking maintenance number of times of desulfurization obviously increases, and just needs parking maintenance once two or three that have.
How to address this problem, become a great problem of puzzlement enterprise.
Summary of the invention
The utility model is the defective that exists in order to overcome above-mentioned prior art, and a kind of semiwater gas desulphurizing device is provided.
The utility model is achieved through the following technical solutions:
A kind of semiwater gas desulphurizing device, comprise the static coke removing appts., roots blower, cooling tower, packing tower, cleaning tower, the gas-liquid separator that connect successively, intersegmental sparger is installed in the wherein said packing tower, void tower, desulfur pump, regenerative pump, regeneration tank also are installed between described cooling tower and the packing tower successively, in the described void tower shower nozzle are installed.
The utility model increases intersegmental sparger in packing tower, make the thionizer uniform gas-liquid distribution; Increase shower nozzle in void tower, adopt the hollow-spraying-tower technology, liquid circulation amount is with import H
2The variation of S content is regulated, at desulfurization import H
2S content is at 5000～6000 mg/Nm
3The time hollow-spraying-tower outlet H
2S content is at 1500～2000 mg/Nm
3。
During work: contain high H
2The water-gas of S, COS etc., semi-water gas through electrostatic tar remover, remove the coal tar in the coal gas, through after the pressurization～40KPa contain high H
2S coal gas is delivered to the hollow-spraying-tower device and is carried out desulfurization after lowering the temperature through cooling tower, and gas out absorbs again through improved packing tower, through the H after the cleaning tower
2S content is about 30～40mg/Nm
3Semi-water gas, through gas-liquid separation be sent to after workshop section.
The utility model is applicable to the desulfurizing and purifying of the unstripped gas of fixed bed gasification in the production processes such as petrochemical complex, Coal Chemical Industry and processes, can effectively alleviate the stifled tower problem of desulfurization, security of system environmental protection, technique are succinct, steady running, simple to operate, cost of investment is few, for the technical progress in the fields such as China ceramic industry, Coal Chemical Industry, has very important realistic meaning.
