Description
Technical field
The present invention relates to a kind of water-coal-slurry and the gasification furnace of natural gas combined vaporizing can be belonged to multiple nozzles
Equipment for gasification technical field.
Background technology
Water-coal-slurry is the fluid fuel obtained with the mixed merga pass Physical Processing of certain proportion by coal, water and additive, by
Be distributed in the north and west area mostly in coal resources in China, transport the coal in the North to the South for a long time, Xi Meidong adjust general layout increased transport
And operation costs, and water-coal-slurry is capable of achieving total enclosing long distance delivery, can reduce transport and the operation costs of coal, therefore water
The industry application of coal slurry technology is received significant attention.
Coal gasification is a kind of mode of coal processing in existing coal chemical technology, and it is oxygen, vapor etc. with coal as raw material
The combustible constituent in coal is converted at high temperature the mistake of gaseous fuel or synthesis gas by chemical reaction as gasifying agent for gas
Journey, the direct product of coal gasification mainly has carbon monoxide, carbon dioxide, hydrogen and a small amount of methane, hydrogen sulfide etc..Water-coal-slurry gas
Change technology is a kind of more water-coal-slurry processing and utilization method of Recent study, and what China realized earliest industrial applications is
Texaco coal slurry gasifiers, its gasification is：Water-coal-slurry is crushed by nozzle in the presence of high speed oxygen, atomization is sprayed into
Gasification furnace, oxygen and vaporific water-coal-slurry are subject to high temperature action, the preheating of rapid experience, moisture evaporation, the dry distillation of coal, volatile matter in stove
Physics, the chemical reaction of the series of complex such as cracking burning and carbon gasification, ultimately produces with carbon monoxide, hydrogen, titanium dioxide
Carbon and wet gas, slag and unreacted carbon that vapor is main component；These products flow out downwardly together reaction
Area, into the shock chamber of gasification furnace bottom, slag and carbon are trapped within water Jing after quenching, solidification, finally fall into slag ladle, Jing rows
Slag system regular discharge, wet gas then obtain the coal gas of cleaning after into the process of coal gas cooling and purifying system.
Existing Texaco gasification furnaces need that first pre- hot nozzle is installed on gasification furnace before check, light pre- thermal jet
Mouth is completed after baker, then is quickly unloaded and installed feed nozzle rapidly and carry out follow-up water-coal-slurry feed pre- hot nozzle and gasified
Journey；But, above-mentioned technique is susceptible to combustion gas in the pre- hot nozzle of removal and during installing feed nozzle, the leakage of oxygen is asked

Slurry, oxygen and natural gas, to improve the gasification performance of gasification furnace, and further improve the hydrogen content in gasification product, improve
The ratio of hydrogen and carbon monoxide.
（2）Multi-jet water-coal-slurry of the present invention and natural gas combined vaporizing stove, the water-coal-slurry-day of its gasification nozzle
So gas hybrid chamber is made up of the necking at two and the tubular structure at middle part, and the necking on top is gradually wealthy from top to bottom, bottom
The necking is tapered from top to bottom.Water-coal-slurry and natural gas are entered after water-coal-slurry-natural gas mixing intracavity by the necking on top and flowed
Dynamic speed is reduced, and water-coal-slurry and natural gas are sufficiently mixed, and the then blended bottom of chamber portion necking of mixture is sprayed by mixture
Mouth sprays at a high speed, atomization, and is clashed into again and be atomized with high speed oxygen, carries out high-temperature gasification with oxygen, this structure
Water-coal-slurry-natural gas hybrid chamber improve mixing, the atomizing effect of water-coal-slurry and natural gas, improve the cooled coal gas of gasification
Efficiency, natural gas can more fully gasify to provide enough hydrogen, further increase hydrogen and carbon monoxide in product
Ratio, generating product can be directly used as the raw material of follow-up chemical industry synthesis.
（3）Multi-jet water-coal-slurry of the present invention and natural gas combined vaporizing stove, the multiple described day of its gasification nozzle
So the axle of gas blowout mouth not the water-coal-slurry-natural gas hybrid chamber side wall into circumference radially.Due to fire rod, igniting
Fuel gas central canal and interior oxygen endless tube are arranged along the axle of water-coal-slurry-natural gas hybrid chamber, make the axle of natural gas spout not mixed
Close chamber side wall circumference radially, it is possible to reduce at a high speed the natural gas of injection is to fire rod, igniter fuel gas central canal and interior oxygen
Endless tube washes away.It is preferred that multiple natural gas spouts are inclined in the counterclockwise direction along clockwise direction or, and it is multiple
The axle of the natural gas spout and the water-coal-slurry-natural gas hybrid chamber side wall into the radial direction of circumference into 5-85 ° of angle.
The natural gas that injection at a high speed can almost be avoided washes away to fire rod, igniter fuel gas central canal and interior oxygen endless tube, so as to prolong
The service life of long compound nozzle；And, in the compound nozzle for so arranging, natural gas will not be because washing away interior oxygen after spraying
Endless tube tube wall and slow down, it is thus possible to form eddy flow in water-coal-slurry-natural gas mixing intracavity, improve natural gas and water-coal-slurry
Mixed effect.
（4）Multi-jet water-coal-slurry of the present invention and natural gas combined vaporizing stove, the water-coal-slurry-oxygen jet is in institute
The top of natural gas nozzle is stated, the water-coal-slurry-oxygen jet is evenly distributed on circumference formed by the furnace shell side wall, described
Natural gas nozzle is evenly distributed on circumference formed by the furnace shell side wall.The setting can ensure that water-coal-slurry in sufficient oxygen
After the lower gasification of effect, the remaining vapor of coal water slurry gasification can continue reaction and provide enough hydrogen with enough natural gass, from
And improve the gasification performance of gasification furnace, and the ratio of hydrogen and carbon monoxide is improved, it is beneficial to gasification product directly as methanol, synthesis
The raw material of oil product is used.It is preferred that water-coal-slurry-the oxygen jet is two, positioned at the top of the furnace shell and it is distributed in described
The both sides of furnace shell central shaft；The natural gas nozzle is two, positioned at the middle part of the furnace shell, the water-coal-slurry-oxygen jet
Underface.
