Device for guiding and condensing raw coal gas of coal pyrolysis furnace

Abstract

The invention relates to a device for guiding and condensing raw coal gas of a coal pyrolysis furnace, which comprises a coal gas blower (1), a air cooler (2), a water-sealed valve (3), a coal coke pump (4), a gas-liquid separator (5), an ammonia water pump (6) and a tar intermediate tank (7), wherein the coal gas blower (1) is connected with the air cooler (2); the air cooler (2) is connected with the gas-liquid separator (5); the water-sealed valve (3) is arranged at the upper end of the gas-liquid separator (5); the coal coke pump (4) and the ammonia water pump (6) are respectively arranged at the left and right sides of the lower end of the gas-liquid separator (5); and the tar intermediate tank (7) is arranged at the right side of the gas-liquid separator (5). The purpose-made water-sealed valve in the device for guiding and condensing raw coal gas can effectively control the suction force of the blower, and an ammonia water sprayer can quickly cool the 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 to facilitate the operation, and the guided raw coal gas is cooled through the air cooler.

Description

technical field [0001] The invention belongs to a coking oven, in particular to a raw coal gas exporting and condensing device of a coal pyrolysis furnace Background technique [0002] At present, most of the coking ovens on the market adopt intermittent coking, and the raw gas is basically exported by gas fans. The ammonia water spraying device is used to cool down, and the suction of the fans cannot be controlled, which makes the pressure in the furnace difficult to control. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a raw coal gas exporting and condensing device of a coal pyrolysis furnace, which can adjust the pressure of the gas-liquid separator through a water-sealed valve, and can reduce the raw gas from high temperature to low temperature, satisfying chemical needs. [0004] The technical scheme of the present invention: a raw coal gas exporting and condensing device of a coal pyrolysis furnace, whi...
