Abstract

The invention relates to a coal gas deep purification and product recovery device of a coal pyrolysis furnace, which comprises a first bucket elevator (1), a second bucket elevator (1), a first discharge tank (2), a second discharge tank (2), a third discharge tank (2), a fourth discharge tank (2), a first air condenser (3), a second air condenser (3), a first discharge device (4), second discharge device (4), an active coke recovery tower (5), a regenerator discharge device (6), a regenerator (7), a fractionating tower (8), a noncondensable gas guider (9), a crude benzene reflux tank (10), an oil-water separator (11), a reflux pump (12), an anthracene oil cooler (13), a three-fraction mixed oil cooler (14), a three-fraction mixed oil intermediate tank (15), an anthracene oil intermediate tank (16), an air blower (17) and a screen box bottom (18). The device realizes that coal gas can be purified and then be reutilized, greatly reduces the emission of waste gas and ensures that various byproducts of coal can be quickly and conveniently extracted.

Description

technical field [0001] The invention belongs to a coking oven, and in particular relates to a deep purification and product recovery device for coal gas in a coal pyrolysis furnace. Background technique [0002] At present, most of the coking ovens on the market adopt batch-type coking. The gas recovery and utilization rate generated in the furnace is low, the energy consumption is large, the environment is polluted, and it is not conducive to energy saving and emission reduction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coal pyrolysis furnace gas deep purification and product recovery device, which can reuse the energy of the gas itself, reduce the discharge of waste gas, and not pollute the environment. [0004] The technical scheme of the present invention: a deep purification and product recovery device for coal pyrolysis furnace gas, which includes: a first bucket elevator 1, a second bucket elevato...
