Abstract

The invention relates to a raw coal gas guide device of a coal pyrolysis furnace, which is additionally provided with a water-sealed valve (13), wherein the water-sealed valve (13) comprises a handwheel (15), a sealing cover (16), a water-sealed valve shell (17), a shaft (18), a water-sealed valve body (19), a gas collecting pipe (20) and an ammonia water sprayer (21); the water-sealed valve body (19) is arranged in the water-sealed valve shell (17); the water-sealed valve body (19) is connected with the shaft (18); the shaft (18) is connected with the handwheel (15); the sealing cover (16) is arranged on the handwheel (15); the lower end of the water-sealed valve shell (17) is connected with the gas collecting pipe (20); and the ammonia water sprayer (21) is arranged on the upper end of the water-sealed valve shell (17). The purpose-made water-sealed valve in the raw coal gas guide device can effectively control the suction force of a blower, thereby ensuring that the pressure in the furnace is uniform; and the ammonia water sprayer can quickly cool raw coal gas from 600 DEG C to 70 DEG C, thereby meeting the requirements of subsequent chemical industry production. Step control is adopted in the raw coal gas guide device, thereby facilitating the operation.

Description

technical field [0001] The invention belongs to a coking oven, in particular to a raw coal gas exporting device of a coal pyrolysis furnace. Background technique [0002] At present, most of the raw gas exporting devices of coking ovens on the market are exported by gas blowers, and the ammonia water spraying device is used to cool down, and the suction of the fans cannot be controlled, which makes it difficult to control the pressure in the furnace and difficult to clean the gas collecting pipe device. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a raw coal gas exporting device of a coal pyrolysis furnace. The water seal valve can be used to control the pressure of the carbonization chamber for rapid adjustment, and can reduce the raw gas from high temperature to low temperature to meet the subsequent chemical needs. [0004] The technical solution of the present invention: a raw gas exporting device of a co...
