Abstract

The invention relates to the technical field of coke oven flue gas treatment, in particular to a coke oven flue gas treatment system. The system comprises a coke oven body; a dust remover is arranged on one side of the coke oven body; a connecting pipe is connected between the coke oven body and the dust remover; a feeding pipe is arranged on the surface of the coke oven body; an opening is formed in one end of the feeding pipe; and the interior of the feeding pipe is movably connected with a feeding and smoke blocking device. A filter screen, a cooling fin, an auger, a motor, a fan and the like are arranged in the dust remover, particulate matter in smoke can be separated out and fed into a combustion furnace again to be combusted, and excessive waste of resources is avoided. According to the coke oven flue gas treatment system disclosed by the invention, when fuel is added, flue gas can be prevented from flying out of the oven, so that the environment can be protected, and the harm of the flue gas to workers can be reduced.

Description

technical field [0001] The invention relates to the technical field of coke oven flue gas treatment, in particular to a coke oven flue gas treatment system. Background technique [0002] Coke oven flue gas is mainly the exhaust gas produced after the combustion of coke oven heating gas, which contains a large amount of N2, H2O, O2, greenhouse gas CO2 and SO2, NOx, dioxin and other pollutants, which can be collected by dust collectors at present The exhaust gas is absorbed, and finally concentrated for treatment, and the useful gas is retained for recycling; [0003] There are some disadvantages in the existing coke oven flue gas treatment system: [0004] 1. When adding coal to the coke oven, it is necessary to open the furnace door at the charging place, which will cause smoke to float out of the coke oven, pollute the environment, not be environmentally friendly, and damage the health of the staff. [0005] 2. The flue gas produced by coke oven combustion is generally se...
