Abstract

The invention relates to the technical field of environmental protection treatment, and discloses a gradient condensation demisting and dedusting system and a method for coke oven gas, and the systemcomprises a tower shell, a circulating cooling system, and a condensation pipe type demisting and dedusting device, a condensation plate type demisting and dedusting device and a condensation fiber demisting and dedusting device which are arranged in the tower shell; the condensation pipe type demisting and dedusting device is positioned on the upper side of the coal gas inlet; the condensation plate type demisting and dedusting device is positioned on the upper side of the condensation pipe type demisting and dedusting device; and the condensation fiber demisting and dedusting device is positioned between the condensation plate type demisting and dedusting device and the coal gas outlet. A stepped condensation demisting and dedusting device is adopted to remove dust-containing tar droplets with different particle sizes in the coke oven gas in a graded manner, so that the tar mist and dust contents in the coke oven gas are reduced; each stage of demisting and dedusting device is connected with the cooling circulation system, so that the collision coagulation and tar mist coagulation effects of each stage of demisting and dedusting device are enhanced, the demisting and dedusting efficiency of the system is improved, and the content of tar mist drops and dust in the system is reduced.

Description

technical field [0001] The invention relates to the technical field of environmental protection treatment, in particular to a system and method for cascaded condensation, mist and dust removal of coke oven gas. Background technique [0002] Coke oven gas is rich in a large amount of carbon and hydrogen compounds, which can be used as raw materials for the production of high value-added chemical products. In the coking industry, after pretreatment such as primary cooling, electric oil capture, and benzene removal, the gas still contains tar droplets, dust and other substances. These impurities affect the normal operation of the compressor and are not conducive to the stability of the subsequent process system. [0003] In order to extend the inspection and maintenance cycle of the compressor, most coking enterprises add an activated carbon adsorption tower in front of the compressor, which will undoubtedly increase the pressure drop of the system, and the activated carbon nee...
