Abstract
The utility model discloses a solid powder fuel reactor, which comprises a shell, a combustion room and a shock chamber, wherein the combustion room is a membrane water cooling wall or a coiler water cooling wall, the shock chamber is a water bath shock chamber, a cooling water jacket is arranged between a deslagging port of the combustion room and a shock chilling ring of the shock chamber, a heat-resisting layer is arranged at the inner side of a cooling water jacket, a water inlet is arranged on the cooling water jacket, and spray holes above the shock chilling ring are distributed at the bottom of the cooling water jacket. The solid powder fuel reactor adopts the structure of combining a dry method feeding combustion room with a water bath shock chamber, and the connection between the combustion room and the water bath shock chamber is improved, so that the problem that the shock chilling ring is easy to deform as the dry method feeding adopts water bath shock chilling is solved, the solid powder fuel reactor not only combines the advantages of the two technologies but also avoids the defect of combination of the two technologies, the running stability is improved, the use cost and the equipment investment are lowered, and the production feasibility is guaranteed. Furthermore, the whole operation effect of a gasification furnace is further improved by improving the structures of the deslagging port and a nozzle.
Description
Technical field
The utility model relates to the vapourizing furnace technical field, especially a kind of solid, powdery fuel reactor.
Background technology
At present, the air-flow bed coal-gasification technology of dry feed is one of state-of-the-art Coal Gasification Technology in the world today.The nucleus equipment of gasifying process is vapourizing furnace, and synthetic gas is completed cooling, ash disposal, humidification in the shock chamber of vapourizing furnace.At present, dry feed is all to adopt membrane wall or coil wall basically, and coil wall is namely that the water wall coil pipe is in conjunction with the liner fire-resistant layer structure; And the shock chamber of dry feed adopts space Quench or useless pot Quench usually.But the washing effect of space Quench is relatively poor, and the ash content in synthetic gas is high, easily causes follow-up production system to be stopped up, and is unfavorable for the long-period stable operation of system; And the facility investment of useless pot Quench is high, and it is low that thermo-efficiency utilizes, and use cost is high, is unfavorable for improving the economic benefit of system.
It is good that the water-bath type Quench has washing effect, and cost is low, is conducive to the long-term operation of system and the raising of economic benefit.Chilling ring is the vitals in the shock chamber, present water-bath type Quench is mainly for the coal water slurry wet feeding, therefore because the temperature of reaction of coal water slurry wet feeding is low, the fly ash content in synthetic gas is little, enters the material of shock chamber from vaporizer very little on the chilling ring impact.And the temperature of reaction of dry feed is high, and the fly ash content in synthetic gas is high, and therefore, the temperature of synthetic gas is also higher, if adopt the water-bath type Quench, can make a big impact to chilling ring, causes its temperature distortion speed fast, and work-ing life is short, therefore, needs improvement badly.
Summary of the invention
The purpose of this utility model is: a kind of solid, powdery fuel reactor is provided, and it had both had advantages of dry feed, can effectively carry out ash disposal to synthetic gas again, and with low cost, and long service life is stable, to overcome the deficiencies in the prior art.
The utility model is achieved in that the solid, powdery fuel reactor, comprises body skin, the combustion chamber, and shock chamber, combustion chamber are membrane wall or coil wall, the shock chamber is the water-bath type shock chamber; Be provided with watercooling jacket between the chilling ring of the lower cinder notch of combustion chamber and shock chamber, be provided with refractory layer in the inboard of watercooling jacket, be provided with water-in on watercooling jacket, be provided with the spray apertures that is in above chilling ring in the bottom of watercooling jacket.
The flow diameter of the lower cinder notch of combustion chamber is reduced into original 1/2～2/3.Dwindling flow area can increase synthetic gas by the flow velocity of lower cinder notch, and the residence time of synthetic gas in lower cinder notch is short, is difficult for stopping up lower cinder notch, and is conducive to keep the temperature of synthetic gas.At present the lower cinder notch of conventional combustion chamber typically has a diameter from 600～1000mm, and it is original 1/2～2/3 that the flow diameter of the lower cinder notch of described combustion chamber is reduced into, and is namely that the flow diameter with lower cinder notch is reduced into 300～670mm.
The burner burner seat of combustion chamber is the rectilinear mounting structure of overhead, is provided with process burner symmetrical more than 3 on burner burner seat, at the center of burner burner seat, igniter burner is installed.Traditional top-jet-type burner is generally single burner, and such structure makes the residence time of coal dust in the combustion chamber short, and efficiency of carbon conversion is not high, mixes inhomogeneous.Adopt said structure to make and produce turbulent flow in the combustion chamber, increase the residence time of coal dust in the combustion chamber, improve efficiency of carbon conversion and mixed effect.
Watercooling jacket is double layer jacket structure.Can increase the flow velocity of water coolant like this, improve cooling performance.Avoided simultaneously cinder notch place's slagging scorification to cause the gas bias current and burnt out the risk of downtake.
Owing to having adopted technique scheme, compared with prior art, the utility model adopts the structure of being combined with the water-bath shock chamber in the combustion chamber of dry feed, and the connection between them is improved, overcome the problem that dry feed adopts the water-bath Quench easily to cause chilling ring to be out of shape, both combined the advanced advantage of two kinds of technology, avoided again two technology in conjunction with the defective that produces, improve operation stability, reduced use cost and facility investment, guaranteed the feasibility of producing.And, by improving lower cinder notch and nozzle arrangements, further improved the overall operation effect of vapourizing furnace.The utility model structure is held simple, and with low cost, result of use is good.
