Description
Technical field
The present invention relates to Gas Production technical fields, more particularly, to a kind of dry coal powder pressure gasifying system.
Background technology
The operation principle of existing typical case's dry coal powder pressure gasifying reactor is summarized as follows：
Raw material coal dust is sent to by burner in the middle part of reactor in combustion chamber, while gas under the action of high-pressure delivery gas
Agent is sprayed into also by burner in the combustion chamber of reactor top.Gasifying agent carries out gasification reaction with coal dust in the combustion chamber,
It is generated with CO, H under the conditions of 1300~1500 DEG C2、CO2Based on raw gas, by combustion chamber to the gas vent on top flow.
Cinder after reaction is flowed downward with molten condition along Inner Wall of Combustion Chamber, and enters shock chamber by combustion chamber lower part,
The lime-ash of melt-flow state cures in shock chamber, cools down.Inner Wall of Combustion Chamber protects inner wall to resist using water-cooling wall form
React hot conditions, while byproduct steam after water wall absorption heat.
The raw gas and its unreacted fine coal of entrainment generated in combustion chamber in the middle part of reactor enters reactor top, upper
Secondary response is carried out in portion space with the steam being added, while the secondary response to absorb heat makes coal gas carry out a degree of drop
Temperature, the coal gas after secondary response is sent out from reactor head gas vent, into radiation waste pot.
The molten state cinder that Inner Wall of Combustion Chamber flows downward from reactor top, also by reactor combustion chamber, shock chamber
Between connection cinder notch enter the shock chamber of bottom of combustion chamber and cure and precipitate under liquid water chilling action in shock chamber
To shock chamber bottom, the slag after solidification is collected by lock hopper system, is discharged.
After raw gas enters radiation waste pot, cooled down to high temperature rough gas using radiation waste pot, while radiation waste pot pair
Produce middle high-pressure steam.Raw gas after cooling down in radiation waste pot sends out radiation waste pot.As raw gas brings radiation waste pot into
Solid lime-ash and molten ash settle into the shock chamber of radiation waste pot bottom, cure molten ash in shock chamber, simultaneously
It is discharged after lime-ash is carried out cooling, into lime-ash lock hopper system.
In the prior art, raw material fine coal and gasifying agent are injected to combustion chamber and are reacted, due to raw material fine coal and gasification
It is consistent with the raw gas flow direction after reaction in combustion chamber that agent sprays into direction, has led to raw material fine coal stopping in the combustion chamber
Stay the time will not the too long or even residence time it is inadequate, this may can cause efficiency of carbon con version not high；Also, it is reacted in combustion chamber
It is generated to high temperature rough gas (1300~1500 DEG C), the indoor Quench water level of Quench is entered hereinafter, to high temperature by guiding tube
Raw gas washed, dedusting and cools to 200~250 DEG C of submittings.Which results in the high temperature rough gas generated in burning
In a large amount of heat be all quenched water and take away and can not efficiently use or largely be recycled, there is a large amount of energy to be wasted
Fall.

From the above, it is seen that the operation principle of the dry coal powder pressure gasifying system of the present invention is summarized as follows：
Raw material dry pulverized coal, gasifying agent are entered by nozzle carries out gasification reaction in combustion chamber 1, reaction is generated with CO, H2、CO2
Based on high temperature rough gas, at the same time combustion chamber 1 be middle and upper part be added steam, make to be added in high temperature rough gas unreacted
Coal dust is reacted again with steam generates CO and H2, further increase efficiency of carbon con version and effective Gas content；Lime-ash after reaction
Combustion chamber 1 is discharged after solidification；
High temperature rough gas enters radiation waste pot 10 after sending out combustion chamber 1, and recovery waste heat by-product is middle and high in radiation waste pot 10
Steam, a middle high-pressure steam part for by-product is pressed to melt down use, remaining is sent outside, the solid separated in radiation waste pot 10
Lime-ash is discharged by ash discharging hole 11.
The raw gas sent out from radiation waste pot 10 enters dry-method dust-removal device, and gas-solid point is carried out in dry-method dust-removal device
From solid after separation is discharged from bottom, and purified coal gas is sent out, and gives up pot into steam.
Steam give up recycle again in pot raw gas waste heat come in by-product, low-pressure steam, the steam of by-product is sent outside, after cooling
Raw gas send outside.
The pipeline by interior village's refractory material between combustion chamber 1 and radiation waste pot 10 is attached.
Compared with prior art, the invention has the advantages that；
Raw material dried coal powder, gasifying agent are entered by the first material inlet 3 of 1 middle and lower part of combustion chamber and the second material inlet 5,
Enter chimney corner degree (opposed tangential way) simultaneously by adjusting the first material inlet 3 and the second material inlet 5 so that the original of entrance
Material dried coal powder, gasifying agent can form the upward flow field of spiral to be biased to tangential way entrance in combustion chamber 1, and reaction generates
Raw gas moves up in a spiral form entrainment of unreacted fine coal.At the same time the raw material fine coal under the collective effect of gravity
Residence time in combustion chamber 1 can accordingly increase, and to effectively improve efficiency of carbon con version, improve reaction efficiency.
Using radiation waste pot 10, shock chamber's gas washing in original technology, cool function replacing, not only can be big
Amount recycles the heat carried in high temperature rough gas, moreover it is possible to which the use for largely reducing chilled water largely reduces sewage discharge.The present invention
Middle combustion chamber lower part shock chamber only retains the solidification of shock chamber's molten ash and lime-ash cooling function in original technology.
Scrubbing tower is replaced using the give up combination of pot of dry method dust+steam, be not only able to raw gas can reach same dedusting,
The effect of cooling, moreover it is possible to which the waste heat for continuing to recycle in raw gas carrys out byproduct steam, improves efficiency of utilization, eliminates washings
Use.
During Gas Production of the present invention, without the addition and generation of any liquid water, waste water is also just prevented
It generates, so as to which matched water treatment system will be needed all to cancel in prior art flow, has not only saved fixation
Investment and operating cost, moreover it is possible to realize the zero-emission of waste water.
Preferred embodiment is that the bottom of the combustion chamber and the radiation waste pot is both provided with shock chamber；
It is both provided with lock hopper system below the shock chamber so that the indoor lime-ash of Quench can enter the lock
Bucket system, and be discharged by the lock hopper system.
