Description
One, technical field
The present invention relates to a kind of chemical industry equipment, particularly a kind of energy converting apparatus, specifically a kind of is the producer of raw material generation semi-water gas with the low density solid biomass.
Two, background technology
Agricultural solid waste such as low-density stalk is existing multiple through the equipment that pyrolytic gasification is converted into geseous fuel.But the vapourizing furnace that puts goods on the market at present owing to characteristics such as the energy resource density of solid biologic are low, and bulk density is little, causes the vapourizing furnace gasification intensity low, and gasification efficiency is low, and fuel gases calorific value is low.Be 900N in the maximum gas production rate of the fixed-bed type vapourizing furnace of operation at present
3/ h, calorific value are 1000～1100kcae/Nm
3Thereby the range of application of restriction vapourizing furnace.
Three, summary of the invention
Producer provided by the present invention is intended to use low-density solid biomass production high quality gas fuel, and problem to be solved is that semi-water gas takes place.
This producer has been used for reference the principle of blue-gas generator, designs in conjunction with the characteristics of solid biomass (calling material in the following text).Concrete technical scheme comprises the slagging device of transmission rig, feed mechanism and its below of body of heater 1 and top thereof, at body of heater 1 inwall thermal insulation layer 2 and flame retardant coating 3 is arranged, and the surface of flame retardant coating 3 is a curved surface, and this curved surface is " girdling the waist " shape in the middle of making burner hearth, as shown in Figure 1." girdling the waist " is divided into two portions up and down with burner hearth, and as shown in phantom in Figure 1, " girdling the waist " is the place that the energy transforms with the burner hearth on top, and promptly material is finished a series of chemical processes such as oxidation, reduction, conversion and gasified; " girdle the waist " with the lower section is ash bed.Be provided with spiral heat exchange tube 4 in the flame retardant coating 3, be intended to make full use of the heat energy in the burner hearth, produce water vapour, return burner hearth generation semi-water gas after water vapour and the air mixed again.Body of heater 1 is provided with semi-water gas outlet 5 and inspection port 6.Be provided with dentation refining rake 7 on the top of burner hearth, its effect is with the even cloth of the material that is added by feeding screw 11 and rolls to improve its density that refining rake 7 is driven by transmission rig, and transmission rig is made up of motor 8, speed reduction unit 9 and axle 10.
The below of body of heater 1 is connected with cinder tank 12, it is outside equipped with cooling water tank 13, vaporized chemical import 14 is arranged on the cinder tank 12, so-called vaporized chemical is meant the mixed gas of air or air and water vapour, lime-ash outlet 15 is arranged at cinder tank 12 bottoms, and lime-ash outlet 15 connects with spiral slag off apparatus 17 and controlled by valve 16.
This producer is operation like this and operation:
Before the igniting preliminary stalk ash is dropped in the stove the about 50cm of floor height by inspection port 6.Then kindling material is dropped on the ash bed from inspection port 6; Solid biomass after giving processing is pushed in the burner hearth by feed auger 11; Start gas blower vaporized chemical (air is or/and the gas mixture of water vapour) is blasted burner hearth, lower floor's biological particles initial burning burning, and heating furnace body and upper materials, body of heater is again with the spiral heat exchange tube 4 in the part heat transferred flame retardant coating 3; The control oxygen-supplying amount gasifies biomass under the insufficient condition of oxygen supply, produce inflammable gas, and inflammable gas is purified the back and supplied with the user by air outlet 5 input gas-purification systems.
Solid biomass generates lime-ash at last through super-dry, restoring transformation, oxidation from top to bottom.The inflammable gas that the igniting initial stage produces is based on CO, after treating that furnace body temperature raises, the water vapour that is produced by spiral heat exchange tube 4 is able to preheating when going into ash bed through cinder tank 12, grate 18 are laggard successively with air mixed, improved gasification agent temperature, reduced cindery temperature simultaneously, in oxidation, reduction reaction, water vapour and CO
2Metallic element katalysis down conversions such as silicon, iron, aluminium are H in lime-ash
2And CH
4, make inflammable gas improve calorific value and quality.
Lime-ash after the gasification, the grate 18 that is rotated are radially passed and are fallen into cinder tank 12; Cinder tank 12 peripheral hardware cooling water tanks 13 are used to reclaim the lime-ash waste heat, gained hot water supply spiral heat exchange tube 4; Cooled lime-ash is discharged by valve 16, slag tapping equipment 17.
This producer is compared with conventional device, and following advantage is arranged: in (1) raw material input stove, be covered with furnace profile under the effect of refining rake 7, and rolled, improved density and rate of heat transfer.Material drying, restoring transformation, is oxidized to lime-ash in folding process.(2) Xuan Zhuan taper type grate 18 can continuously be removed lime-ash, thereby has guaranteed the stability of gasification bed, helps improving the continuity of combustion gas quality and production.(3) UTILIZATION OF VESIDUAL HEAT IN and CO to greatest extent
2The conversion inflammable gas is another characteristics of this vapourizing furnace.Utilize body of heater inner member and lime-ash waste heat to improve gasification temperature, thereby improved the zone of oxidation temperature, strengthened gasification intensity, improved material gasification rate and combustion gas quality; Cooling body of heater and the water vapour that produces participates in reaction, in lime-ash under the katalysis of metallic element, the CO that gasification is generated
2Be transformed into H
2, CH
4, so not only made full use of the carbon in the raw material, reduce the proportion of CO in combustion gas, and improved fuel gases calorific value, improved the security that combustion gas is used.In addition, the Seal Design of each running gear has prevented the infiltration of air, has reduced the oxygen level of combustion gas, also helps improving the security that combustion gas is used.This producer is compared with the vapourizing furnace with the cross section, and gasification intensity improves 1.5～2.0 times, and fuel gases calorific value can be mentioned 2000kcae/N m
