Description
Technical field
The present invention relates to tar ammonia delivery pipes after low order fine coal retorting technique field more particularly to a kind of gas-liquid separator
Road structure and carrying method.
Background technology
The low coal of low-order coal, that is, degree of coalification, the coal quality is low, and in China, distribution is wide, and yield is big.In low order coal mining
It will produce a large amount of fine coal in the process (granularity is in 13mm coals below).Using external-heat low order fine coal gas retort to low order fine coal
When carrying out destructive distillation, the raw coke oven gas generated in gas retort necessarily carries a large amount of dust during quickly operation outward.Contain
For the raw coke oven gas of a large amount of dust after the gas gathering system of destructive distillation furnace roof sprays ammonia scrubbing and cools down, dust has been put into ammonium hydroxide
In, meanwhile, the part gaseous state tar in raw coke oven gas also enters in ammonium hydroxide after condensation, and dust and tar are together formed
Tar slag.The mixture of the tar, tar slag, ammonium hydroxide and the raw coke oven gas that are come out from destructive distillation furnace roof gas gathering system passes through gas-liquid separator
Afterwards, raw coke oven gas is sent to recovery of chemical products workshop section by raw coke oven gas conveyance conduit and carries out gas phase treatment；Tar, tar slag and ammonium hydroxide are by tar
Ammonium hydroxide conveyance conduit is sent to subsequent recovery of chemical products workshop section and carries out liquid phase processing.
Problems with existing for existing tar ammonia transmission process：Since there are many type of low order fine coal, different sources,
(when coal is by destructive distillation, the fugitive constituent in coal will convert the fugitive constituent even contained in the low order fine coal of same place of production different depth
For raw coke oven gas) have prodigious difference, the technological parameters such as temperature, pressure can also change when along with destructive distillation, which results in from
Furnace roof comes out raw coke oven gas flow and will change at regular intervals.Correspondingly, the coke come out from destructive distillation furnace roof gas gathering system
Oil, tar slag, ammonium hydroxide and raw coke oven gas gas-liquid mixture in the ratio of each ingredient can also change.Gas-liquid mixture passes through gas
After liquid/gas separator, often entrainment of variable amount of raw coke oven gas in tar, tar slag and the ammonium hydroxide separated, measures small, have sometimes
When amount can be very big.
Tar, tar slag and ammonia water mixture containing raw coke oven gas are transported to the tar ammonia of subsequent recovery of chemical products workshop section
The facilities such as water separating tank carry out liquid phase processing, will accumulate a large amount of waste coal over time, in tar and ammonia water separation hopper
Gas, it is sufficiently bulky due to tar and ammonia water separation hopper, it is impossible to accomplish to be fully sealed.It is positive pressure inside tar and ammonia water separation hopper
When, the raw coke oven gas accumulated in tar and ammonia water separation hopper will leak into air, pollute the environment, when there is worker's process
When gas poisoning can occur, cause personal safety accident.It is more dangerous when being negative pressure inside tar and ammonia water separation hopper, it is external
Air can enter tar and ammonia water separation hopper and be mixed with the raw coke oven gas accumulated inside tar and ammonia water separation hopper, reach certain proportion (coal
The explosion limit of gas) when will explode, cause serious work safety accident.
Invention content
It, can will be through gas the present invention provides tar ammonia conveyance conduit structure and carrying method after a kind of gas-liquid separator
