Abstract

The invention discloses a carbonizing tail gas treatment method. The carbonizing tail gas treatment method comprises the following steps that 1, tail gas produced by a carbonizing furnace is cooled to obtain condensate liquid and cooling gas; 2, the cooled gas is returned to the carbonizing furnace to serve as a fuel; 3, the condensate liquid obtained in the step 1 is subjected to separating treatment to obtain wood tar and wood vinegar. The tail gas produced by the carbonizing furnace is directly cooled, different products are effectively utilized, no pollution is produced, the operation is simple, additional carbonizing fuel is decreased, and the cost is saved.

Description

Charing exhaust gas treating method
Technical field
The present invention relates to charring process field, especially a kind of charing exhaust gas treating method.
Background technology
Charing, also known as destructive distillation (dry distillation), is that solid fuel is carried out into heat chemistry processing method, by coal, wood Material, oil shale etc. are decomposed into gas (coal gas), liquid (tar) and solid (coke) product in isolation heated under air, and tar steams Gas is escaped with coal gas from coke oven, can be recycled, and coke is then released by coke oven.Contain many kinds of substance in charing tail gas, if Directly discharge, functional mass is not used in meeting contaminated air, and tail gas.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of charing exhaust gas treating method, easy to operate, pollution-free.
In order to realize foregoing invention purpose, the present invention provides following technical scheme：One kind charing exhaust gas treating method, including Following steps：
(1), the tail gas that retort is produced, through cooling treatment, obtains condensate liquid and cooling gas；
(2), cooling gas is back to retort as fuel；
(3) the separated treatment of condensate liquid that, (1) step obtains, obtains wood tar and pyrolkigneous liquid.
Further, (1) step is cooled to be cooled to 30~38 DEG C.
Further, step (1) in, coolant with cooling gas separated using gas-liquid separation mode.
Compared with prior art, the present invention has advantages below：The direct cooling treatment of tail gas produced to retort, obtains Different products be utilized effectively, it is pollution-free, it is simple to operate；Additional charing fuel is reduced, it is cost-effective.
Specific embodiment
With reference to embodiment, the present invention will be described in detail, the description of this part be only it is exemplary and explanatory, no Reply protection scope of the present invention has any restriction effect.
Embodiment 1
One kind charing exhaust gas treating method, comprises the following steps：

Embodiment 2
One kind charing exhaust gas treating method, comprises the following steps：
(1), the tail gas that retort is produced, is cooled to 30 DEG C for the treatment of, and gas-liquid separation mode obtains condensate liquid and cooling gas；
(2), cooling gas is back to retort as fuel；
(3) the separated treatment of condensate liquid that, (1) step obtains, obtains wood tar and pyrolkigneous liquid.
Embodiment 3
One kind charing exhaust gas treating method, comprises the following steps：
(1), the tail gas that retort is produced, is cooled to 35 DEG C for the treatment of, and gas-liquid separation obtains condensate liquid and cooling gas；
(2), cooling gas is back to retort as fuel；
(3) the separated treatment of condensate liquid that, (1) step obtains, obtains wood tar and pyrolkigneous liquid.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
