Abstract

The invention discloses a bypass valve system for a coke oven flue gas purification device. The bypass valve system comprises an original flue, a clean flue, a bypass flue valve, and a sealing device.The bypass flue valve is arranged on a coke oven gathering flue and separates the coke oven from the flue; the original flue and the clean flue are arranged on the two sides of the bypass flue valve;the sealing device is arranged for sealing between the original flue, the clean flue, the bypass flue valve, and the coke oven gathering flue. The gas is introduced to the flue gas purification device through the original flue to be processed to reach the standard; and then the gas is sent back to the clean flue and is directly discharged through a chimney. According to the bypass valve system for a coke oven flue gas purification device, the bypass flue valve, the original flue, the clean flue, and the sealing device are additionally arranged on the existing coke oven flue gas system, so that the arrangement is compact; the construction process is simplified; the construction time is reduced; and meanwhile the sealing performance of the system is ensured.

Description

technical field [0001] The invention belongs to the technical field of controlling air pollutants discharged from coke oven flue gas, and in particular relates to a bypass valve system of a coke oven flue gas purification device. Background technique [0002] GB16171 "Emission Standard of Pollutants for Coking Chemical Industry" was officially promulgated and implemented in 2012, and the air pollution problem in the coke oven industry has become a key target of environmental protection. According to the latest environmental protection index requirements, the existing coke oven flue gas cannot be discharged directly through the chimney, and subsequent desulfurization and denitrification purification facilities must be added. [0003] The existing coke oven collecting flue is generally laid underground and connected horizontally to the root of the chimney. The interior of the flue is built of refractory bricks, which is a vault structure, and the exterior of the refractory br...
