Desulfurization waste liquid pyrolyzer with protective device

Abstract

The invention discloses a desulfurization waste liquid pyrolyzer with a protective device. The desulfurization waste liquid pyrolyzer comprises a coking chamber coal charging hole, the protective device, a desulfurization waste liquid injector and a desulfurization waste liquid pyrolysis channel. The desulfurization waste liquid injector is fixed in the coking chamber coal charging hole through the protective device. Through the desulfurization waste liquid pyrolysis channel, the desulfurization waste liquid is pyrolyzed in a coking chamber. According to the device, the desulfurization waste liquid is fully pyrolyzed by waste heat of raw coke oven gas at the top of the coking chamber, and the desulfurization waste injector is protected so that damage caused by the desulfurization waste liquid dropped in coke in the coking chamber or sprayed to the wall of the coking chamber is avoided.

Description

technical field [0001] The invention relates to a desulfurization waste liquid pyrolysis device, in particular to a desulfurization waste liquid pyrolysis device with a protection device installed in a coal charging hole of a coke oven carbonization chamber of a coking enterprise. Background technique [0002] In the coking production process, most enterprises will produce toxic and harmful high-pollution waste liquid containing thiocyanate, thiosulfate, sulfate, etc. when they adopt the catalytic wet oxidation desulfurization process. Utilize the high temperature of the raw gas at the top of the carbonization chamber or the space of the riser to carry out catalytic or non-catalytic pyrolysis treatment on the secondary salt of the desulfurization waste liquid, and the pyrolysis product enters the gas recovery system with the pyrolysis gas to achieve the purpose of treating waste with waste. [0003] The top structure of the carbonization chamber includes the furnace roof and...

AI Technical Summary

Problems solved by technology

The device is installed at the root of the riser pipe or the top space of the carbonization chamber connected with the riser pipe. Since the distance from the root of the riser pipe or the top space of the carbonization chamber connected with the riser pipe to the gas collecting pipe is only 3m, the reaction time is short, which may cause When the temperature is low, the desulfurization waste liquid cannot be completely decomposed when it enters the gas recovery system with the gas

In addition, this device also has the problem that the nozzle for spraying desulfurization waste liquid is not equipped with a protective device. If the sprayed desulfurization waste liquid is not atomized in time, it may condense into droplets and drip into the furnace wall or coke.
