Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, a kind of system that tar slag is handled by totally-enclosed anaerobic cracking reaction described in the utility model, bag
Include dispensing feed unit 1, anaerobic cracking reaction unit 2, cracking gas recovery unit 3 and combustion gas tail gas recycle unit 4；The dispensing
Feed unit 1 is made of sequentially connected ultracentrifuge, collection dregs of fat medial launder and tar slag delivery pump, tar slag delivery pump
The feed inlet of cracking reaction kettle in outlet connection anaerobic cracking reaction unit 2；Anaerobic cracking reaction unit 2 by cracking reaction kettle and
Air preheater forms, and cracking reaction kettle sets feed inlet, nitrogen/steam inlet, coal gas burner, tailings outlet and tail gas
Reuse mouth；Air preheater connects cracking reaction kettle, air preheater by gas pipeline before preheating with gas pipeline after preheating
In addition combustion air inlet and net air outlet are set；Cracking gas recovery unit 3 is by sequentially connected eddy flow slag-removing unit, secondary settlement
In addition tank, condenser, oil water separator composition, eddy flow slag-removing unit connect the tailings outlet of cracking reaction kettle；Combustion gas tail gas returns
Receive unit 4 to be made of exhaust cleaning system and air-introduced machine connection, the gas access for being vented cleaning system connects not coagulating for condenser
Gas vent, the recycling tail gas mouth of the air outlet connection cracking reaction kettle of air-introduced machine.
The cracking reaction kettle is rotation heated type cracking reaction kettle.
The oil export of the oil water separator connects back to collection tank by oily medial launder, and water out is connected by water medial launder
Technique sink.
The tar residues processing technique process realized using system described in the utility model is as follows：
1) dispensing is fed：
Tar slag carries out dispensing with coke powder, and coke powder by weight percentage accounts for the 20%~500% of tar slag total amount；Tar slag
Add in cracking reaction kettle and mix by proportioning with coke powder；
2) the totally-enclosed anaerobic cracking reaction of gas heating：
After cracking reaction kettle feeds, after nitrogen or steam displacement fuel gas, under totally-enclosed oxygen free condition, lead to
Combustion gas is crossed to heat to cracking reaction kettle；When temperature of charge reaches more than 100 DEG C, vapor starts to volatilize, as temperature continues
Rise, tar start to volatilize, and when temperature of charge reaches more than 350 DEG C, generation cracks, polymerisation；When temperature of charge reaches 500
DEG C when, liquid component therein all separates out；It is left the tailings of similar coal coke after cinder pyrolysis, when which relatively fills kettle
Volume of material be greatly decreased, through nitrogen or steam cooling displacement fuel gas after, tailings is removed, is used for after natural cooling
Coal blending is used as boiler oil；
3) cracking gas recycles：
Oil gas from cracking reaction kettle initially enters eddy flow slag-removing unit, and the fine solid particle and drop in oil gas are revolving
Acted in stream slag-removing unit by centrifugal force, get rid of to wall and under the effect of gravity along wall downlink, concentration and be deposited in eddy flow and take off slag
Device bottom；Oil gas after de- slag enters secondary settlement tank, and remaining a small amount of fine solid particle is deposited in secondary settlement pot bottom；
Enter condenser system by the oil gas that eddy flow takes off slag and settles after-purification, condensed liquid is sent to water-oil separating
Device, the process water isolated are sent to technique sink by water medial launder, and the oil isolated is sent to recycling oil groove through oily medial launder；No
The on-condensible gas for the similar coal gas that can be condensed is sent to coke-oven plant with air-introduced machine and inhales gas piping, or sends back to and split after washing oil washs
The combustion system of solution reaction kettle is used for heat supply.
Cracking reaction kettle uses totally-enclosed feeding manner, that is, first passes through head tank and put into coke powder in proportion；Tar slag first from
Ultracentrifuge is discharged to medial launder, then is pumped to cracking reaction kettle material inlet by tar slag conveying.
The cracking reaction kettle is using rotation mode of heating.
Tailings after cracking reaction kettle heats for the first time is not discharged first, continues to participate in follow-up cracking reaction several times, participation
Number determines according to dregginess in tar slag, and when follow-up cracking reaction need not put into coke powder, only put into tar slag.
In the utility model, into tar slag be incorporated coke powder be in order to enable the tailings after cracking reaction smoothly to discharge,
Non-sticky kettle.
, can be by artificial if being discharged to this outdoor mode of tar small handcart using tar slag to feed to cracking reaction kettle
A certain proportion of coke powder is first put into, then manually launches tar slag.
After the completion of first time cracking reaction, fed intake for the second time, without putting into coke powder, only put into tar slag, thing in kettle
Material not discharge, continues with, and reaches certain cycle-index and then discharge waste residue, is circulated into next round.
To be sufficiently mixed in kettle material and reacting thorough, cracking reaction kettle is using rotating mode of heating.
By way of scrubbing tower, useful incoagulable gas is recycled as far as possible, ensures tail gas qualified discharge,
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
