Abstract
The utility model discloses a coke oven gas deep purification pretreatment system for direct-fired machine power generation. The coke oven gas depth purification pretreatment system comprises a dry-method desulfurization tower, a compressor, a wet-method desulfurization tower, a light oil washing naphthalene scrubber, coke filters, a water scrubber, and an aggregation type filter. The H2S gas in the coke oven gas is removed by the wet-method desulfurization tower, the coke oven gas enters the light oil washing naphthalene scrubber to remove the naphthalene from the coke oven gas, and then the coke oven gas is filtered by two parallel coke filters and secondarily desulfurized by the iron oxide dry-method desulfurization tower, and then filtered by the water scrubber and the aggregation type filter, thus most of the H2S in the coke oven gas is removed; finally the coke oven gas is pressed by the compressor and then enters a combustion chamber of a direct-fired machine. The operation period of the compressor is long, and the long-period full-load stable operation can be performed by a direct-fired machine power generation system.
Description
Technical field
The utility model belongs to generating equipment, relates in particular to a kind of Central Air-Conditioner is generated electricity and carries out the device of deep purifying with oven gas.
Background technology
The Central Air-Conditioner generating refers to the rich coke oven gas desulfurization of coke oven is processed, remove sulphur-containing substance wherein, coal gas is reached directly enter after certain pressure the Central Air-Conditioner combustion chamber through entering compressor after filtering, through the igniter burning, produce high temperature and high pressure gas, propelling gas turbine engine rotarily drives the generator generating, generating high-temperature tail gas later enters waste heat boiler, and recovery waste heat produces steam, at last, waste gas is through smoke stack emission.
Oven gas purifies, and does not also have now in the world experience to follow, and is all now to use simple dry desulfurization, and emphasis is removed the H in oven gas
2S, the shortcoming of this technique maximum be do not consider other as impurity such as tar, naphthalene, benzene, cause the compressor operation cycle short, Central Air-Conditioner oven gas nozzle often burns out, single-purpose filtering element stops up serious.
Summary of the invention
The purpose of this utility model is to provide a kind of Central Air-Conditioner generating with oven gas deep purifying pretreatment system, can effectively purify oven gas, improves the service life of equipment.
for achieving the above object, the utility model adopts following technical scheme: a kind of Central Air-Conditioner generating oven gas deep purifying pretreatment system, comprise dry desulfurizing tower and compressor, also comprise wet desulfuration tower, the lightweight washing oil is washed the naphthalene tower, coke filter, water scrubber and coagulation type filter, the gas outlet of wet desulfuration tower is connected by pipeline with the air inlet that the lightweight washing oil is washed the naphthalene tower, the air inlet that the lightweight washing oil is washed the gas outlet coke filter of naphthalene tower is connected by pipeline, the gas outlet of coke filter is connected by pipeline with the air inlet of dry desulfurizing tower, the gas outlet of dry desulfurizing tower is connected by pipeline with the air inlet of water scrubber, the gas outlet of water scrubber is connected by pipeline with the air inlet of coagulation type filter, the gas outlet of coagulation type filter is connected by pipeline with the air inlet of compressor.
Described coke filter has two, is parallel way and connects.
Described coagulation type filter has two, is parallel way and connects.
Adopt the oven gas deep purifying pretreatment system of technique scheme, oven gas is sloughed H through wet desulfuration tower
2After S gas, advance the lightweight washing oil and wash the naphthalene tower and take off naphthalene, then filter through two coke filters in parallel, then enter iron oxide dry desulfurizing tower secondary desulfuration, then after water scrubber and coagulation type filter, can remove most H in oven gas
2S, the Central Air-Conditioner combustion chamber is entered in the pressurization of compressed machine.The compressor operation cycle is long, and the Central Air-Conditioner electricity generation system can be organized long period stable operation at full capacity.
