Waste gas cracking device

Abstract

The invention relates to waste gas treatment, in particular to a waste gas cracking device. The technical problem to be solved by the invention is to provide the waste gas cracking device. The waste gas cracking device comprises a discharge chimney, a cooling pipe, a tar adhesion ammonia washing mechanism, a tar residue compression mechanism, a digestion cracking mechanism, a stepping motor and acontrol display; wherein an inner interlayer of the exhaust chimney is connected with the cooling pipe in a sleeving manner; a tar adhesion ammonia washing mechanism is arranged at the top of the right end of the discharge chimney; the middle part of the bottom end of the tar adhesion ammonia washing mechanism is in bolted connection with the extension pipe; and the bottom plate of the tar adhesion ammonia washing mechanism is connected with a bottom frame. The device achieves the effects that the coke sulfur waste gas is recycled again, after the waste gas is treated, carbon-containing organic matter in the waste gas is extracted through biological thermal cracking, then the organic matter is converted into carbon black through ignition, the carbon black is hung and collected and used forplastic manufacturing, the utilization rate of crude oil is increased, and meanwhile the effect of waste gas emission on air is reduced.

Description

technical field [0001] The invention relates to waste gas treatment, in particular to a waste gas cracking device. Background technique [0002] Coal tar can be divided into low-temperature coal tar, medium-temperature coal tar and high-temperature coal tar according to the carbonization temperature. Coal tar obtained in coke production belongs to high-temperature coal tar. It is one of the coke oven gas purification products condensed and separated during the crude gas cooling process. Ethylene tar is a by-product of hydrocarbon cracking to produce ethylene, which can be used to produce carbon black raw materials, and can also be used as fuel for industrial boilers. [0003] Prior Art Chinese Patent CN103816796A Aiming at the problem that the existing coking industry does not have an economical and reliable desulfurization and denitrification process applied to actual production, it discloses a coke oven flue gas desulfurization and denitrification process. The remaining ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the disadvantages in the prior art that the exhaust gas still contains a large amount of untreated tar, which will pollute the air after being discharged, and the tar is cooled and dropped in the air, it is easy to cause soil pollution, and even pollute surface drinking water in serious cases. The present invention The technical problem to be solved is to provide a waste gas cracking device
