Each flow detection controller F5 of each gasifying agent to supply gas on pipeline detect and be sent to overall operational device Y1 gasifying agent it is real-time
Data on flows compares and feedback regulation, so that gasification agent flux is adjusted to appropriate value, to will be fed into gasification reactor 5
The flow and gasifying agent containing feedstock hydrocarbon flow control in a certain proportion.When in feeding gasification reactor 5
When the flow of flow and gasifying agent containing feedstock hydrocarbon deviates the proportional region, automatic trigger protective device carries out protection cutting,
The feeding for stopping the gentle agent containing feedstock hydrocarbon, to stop entire gasification process.
Carry out gasification reaction in gasification reactor 5 containing feedstock hydrocarbon and gasifying agent, generation with CO+H2Based on raw gas
The inanimate matter ash for carrying molten state enter in the gas-guide tube of rough coal Gas Cooler 6 and come into full contact with its internal water carry out it is cold
But, raw gas and inanimate matter ash are obtained, wherein inanimate matter ash settles into rough coal Gas Cooler 6 under gravity
In the cooling water of bottom, the lime-ash of cooling water lower part deposition is discharged by ash discharge technique through thick slag discharge system 7, and middle and upper part is cooling
Water because after (180 DEG C~300 DEG C) of the Heisui River discharge rough coal Gas Cooler 6 containing tiny ash content into wastewater treatment working section III into
Row is further processed；Raw gas is separated from water because solubility in water is lower, is turned back and is risen to the top of rough coal Gas Cooler 6
Portion is discharged from outlet, is further washed subsequently into raw gas washing, purifying device 8, in raw gas washing, purifying device 8, is taken
Raw gas with tiny ash is in contact with the return buck from waste water water treatment system (III), is washed by intrusive water-bath
It washs and washs the mode combined with rising contact column plate, remove the tiny ash carried in raw gas, obtain clean up to standard
Raw gas and washing Heisui River (150 DEG C~280 DEG C) containing fine ash, raw gas are discharged from the top of raw gas washing, purifying device 8
And be sent into downstream section as the final products of this gasification process and utilized, the washing Heisui River (150 DEG C~280 containing fine ash
DEG C) after the bottom of raw gas washing, purifying device 8 is collected, a part send the cooling to gas cooler 6 as high temperature rough gas
Water uses, and another part send to subsequent grey water treatment system (III) and is further processed.
In wastewater treatment working section III, in rough coal Gas Cooler 6 containing tiny ash content Heisui River (180 DEG C~300 DEG C) and
(150 DEG C~280 DEG C) of the washing Heisui River containing fine ash in raw gas washing, purifying device 8, which enters in buck inspissator 9, to be subtracted
Pressure flash distillation, moisture vaporization forms (130 DEG C~220 DEG C) of flash steam separation and is discharged from the top of buck inspissator 9, into buck
In heater 11, remaining unvaporized liquid and fine ash are discharged from the bottom of buck inspissator 9, carry out into dope filter 10
Filtering, obtains fine ash and buck, fine ash (water content is 40wt%~60wt%, and temperature is 50 DEG C~80 DEG C) be accumulated as fine slag from
The bottom of dope filter 10 is discharged, and (dust burdening enters in grey water collector 13 buck in 5wt% or less), removes least a portion of ash
Water is sent to formation outlet water outside gasification process section to reduce accumulation of the salinity in water body, most buck (80 DEG C~110
DEG C) give into grey water heater 11.
After moisture vaporization is formed in buck inspissator 9 (130 DEG C~220 DEG C) of flash steam enter in grey water heater 11,
