A hearth (12) is formed by the periphery of an upper and a lower sandwich structures which are isolated, wherein the upper sandwich layer is a water storage chamber (1); the lower sandwich layer is a preheating chamber (3). A preheating pipe (5) penetrating through the hearth (12) is arranged in the preheating chamber (3); an igniting pipe (4) penetrates through the hearth; a heating pipe (15) connected with a power supply is arranged in the igniting pipe (4). A flow meter (7) is connected between the water storage chamber (1) and the preheating chamber (3); a hollow screw rod (6) is arranged between the inner and the outer walls of the lower part of the preheating chamber (3). The utility model is mainly used for a biomass gasifying furnace.
Description
Technical field
The utility model relates to a kind of gasifying biomass furnace igniting and gasification installation.
Background technology
Biomass gasifying furnace is a kind of equipment that biological anoxycausis produces inflammable gas.At present, the biomass gasifying furnace of selling on the market is the vapourizing furnace of fuel with bavin, straw etc. especially, all can only burn down a part of raw material; Slag is charcoal or the siccative that varies in size, and can not be gasified totally.Existing simultaneously biomass gasifying furnace also exists igniting difficult, sootiness operator, easy carbon monoxide poisoning when lighting.Can not reach environmental requirement, also just give to promote the use of and brought restriction.
Summary of the invention
The purpose of this utility model provides a kind of gasifying biomass furnace igniting and gasification installation of being used for.
The technical scheme that its technical problem that solves the utility model adopts is: isolated up and down sandwich structure surrounds burner hearth 12, the top interlayer is retaining chamber 1, the bottom interlayer is a preheating chamber 3, the point preheating tube 5 that passes burner hearth 12 is installed in the preheating chamber 3, adorn heat-generating pipe 15 in the ignitron 4 and pass burner hearth 12, heat-generating pipe 15 connects external power source, connects under meter 7 between retaining chamber 1 and the preheating tube 5; The other end of preheating tube 5 and preheating chamber 3 communicate, empty screw rod 6 in having between the inside and outside wall of preheating chamber 3 bottoms.In the interior empty screw rod 6 passage 17 is arranged, hole 18 communicates with preheating chamber 3, and the other end outlet 19 communicates downwards and with burner hearth 12.Passage 17 has internal thread and connects another bolt 14 near the port of nut.
The beneficial effects of the utility model are, water is controlled by under meter, after preheating tube and preheating chamber, vaporization and with the air thorough mixing, solved water and can not be converted into steam fully and enter burner hearth and reduce the problem of furnace temperature; Can fully react with biomass after entering burner hearth, improve transformation efficiency.Because outlet 19 is installed downwards, makes the gasification reaction zone extend to burner hearth bottom as far as possible, has promptly enlarged the combustion gasification district, thereby has improved conversion reaction efficient, can accomplish that biomass are gasified totally in stove.Owing to set up ignitron, energy automatic electrical ignition can not solved the difficult problem of igniting by sootiness when making igniting, avoids carbon monoxide poisoning.
Relatively prove by experiment: the fuel that weight is identical, after adopting the utility model, the vapourizing furnace gas production rate is higher than 2-3 times of existing vapourizing furnace, moreover, low to demanded fuel, as long as energy incendiary material, thereby fuel source is widely arranged, can make fuel as firewood, straw, straw, husk, wood chip, coal etc. and various combustiblematerials.

Fig. 1 is the assembling synoptic diagram of this utility unit.
Fig. 2 is a kind of distributed architecture synoptic diagram of ignitron and preheating tube and interior empty screw rod.
Fig. 3 is interior empty screw rod synoptic diagram.
Among the figure: 1. retaining chamber, 2. water-in, 3. preheating chamber, 4. ignitron, 5 water preheat pipes., 6. in empty screw rod, 7. under meter, 8. ash output hole, 9. inlet mouth, 10. air outlet, 11. water outlets, 12 burner hearths, 14 bolts, 15 heat-generating pipes, 17. passages, 18 holes, 19 outlets.
Embodiment
By Fig. 1 and Fig. 2 as can be known, isolated up and down sandwich structure crosses burner hearth 12, and the top interlayer is retaining chamber 1, and the bottom interlayer is a preheating chamber 3, and preheating tube 5 passes burner hearth 12, ignitron 4 pass burner hearth and in dress heat-generating pipe 15.Ignitron 4 passes burner hearth from shell by preheating chamber 3, and terminal is fixed on the inwall of burner hearth 12.Preheating tube 5 one ends connect under meter, and the another port leads directly to preheating chamber 3.Connect under meter 7 between retaining chamber 1 and the preheating chamber 3, empty screw rod 6 in symmetry is installed between the inside and outside wall of preheating chamber 3 bottoms.Have passage 17, one stomidiums 18 to communicate with preheating chamber 3 in the interior empty screw rod 6, the other end outlet 19 communicates downwards and with burner hearth 12.Passage 17 has internal thread near the port of nuts, with bolt 14 bolts tightly in the outer end of interior empty screw rod 6.Heat-generating pipe 15 links to each other with external power source.
During use: at first turn on the power switch, when heat-generating pipe 15 generates heat to the 500 degree left and right sides, ignitron 4 igniting.Simultaneously gas blower is by inlet mouth 9 oxygen supplys, oxygen through preheating chamber 3 preheatings after, 18 enter burner hearth 12 to outlet 19 from the hole, and combustion reactions takes place; Thereby solved manual ignition's inconvenience, realized igniting automatically.Shut power supply after lighting material, can take out heat-generating pipe 15 at any time, be beneficial to its permanent use.Open under meter 7 at the same time, and control flow well, water enters two pipelines of preheating tube 5, during preheating tube 5 process burner hearths 12, by heat, the water of the inside becomes water vapour, water vapour enters preheating chamber 3 back and continues preheatings, and enters burner hearth by hole 18 to outlet 19 after the air mixed and reacts.Because outlet 19 is downward installations, from burner hearth bottom, has guaranteed the thickness of combustion gasification layer during combustion gasification, can allow material be gasified totally; Solved the bad defect of traditional vapourizing furnace gasification result, traditional vapourizing furnace bottom is remaining to be the charcoal slag, also can be gasified totally with charcoal independent behind this device, exceeds 2～3 efficiency-timed rates than existing stove.Because of the installation of under meter, it is readable, controlled that the water amount of vaporization has been accomplished, prevented to fall when vapourizing furnace moisturizing in the past is too much the phenomenon of end furnace temperature or spray fire extinguishing, and moisturizing is the not good situation of gasification result after a little while.
