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 atmospheric pollutant control for coke oven flue gas emission, and particularly relates to a bypass valve system of a coke oven flue gas purification device. Background technique [0002] The GB16171 "Emission Standard of Pollutants for the Coking Chemical Industry" was officially promulgated and implemented in 2012, and the air pollution problem in the coke oven industry has become a key environmental protection target. According to the latest environmental protection index requirements, existing coke oven flue gas cannot be directly discharged through the chimney, and subsequent desulfurization and denitration purification facilities must be added. [0003] The existing coke oven summary flue is generally laid underground and connected horizontally to the root of the chimney. The interior of the flue is built with refractory bricks, which is a vault structure, and the exterior of the refractory bricks is cove...
