Embodiment
The first embodiment: as shown in Figure 1 and Figure 2, this dual control stalk gasifier comprises body of heater 1, gasification Room 3 and combustion chamber 6, and 6 tops, combustion chamber have fire door 7 and inspection window 9, one sides that flue 4 is arranged.Be provided with double-layer water jacket 2 around body of heater 1, water jacket 2 is to picking out hot-water line 5 and return water pipe 19, and the two ends that hot-water line 5 and return water pipe 19 can be received the city radiator consist of heat supplying loop.Be provided with the gas line 10 of setting in vaporizer 3, gas line 10 upper ends enter combustion chamber 6, are provided with combustion gas 8 in combustion chamber 6.In conjunction with Fig. 3 Fig. 4 as seen, the outside of combustion gas 8 is bowl-shape covers 20, and bowl-shape cover 20 1 sides have rotation pipe 23 and gas line 10 to be rotationally connected, and in bowl-shape cover 20, pillar 21 are arranged, be provided with gland 22 above pillar 21, around gland 22 and gapped between the upper limb of bowl-shape cover 20.
Body of heater 1 outside is provided with the blast tube 13 of a setting, blower fan 14 is connected at blast tube 13 middle parts, blast tube 13 epimeres are equipped with control valve 12, hypomere is equipped with lower control valve 15, the upper end of blast tube 13 has upcast ventilation pipe 11 to fold into vaporizers 3 to connect gas line 10, and blast tube 13 lower ends have lower air conduit 16 relative with even fan housing 18 outsides.
During work, 8 pendulum of the combustion gas in combustion chamber 6 on one side, are taken away the upper cover of vaporizer 3, the stalk fuel of the pulverizing of packing into is also lighted.Generally, oxygen can enter vaporizer 3 by the ash port 27 in the middle of soot door 17 and even fan housing 18 base plates 26, after burning for some time, close soot door 17, the interior anoxic of vaporizer 3, stalk are under the state that is not going out also not, and temperature remains on the temperature of straw splitting, be fit to the cracking of stalk, produce inflammable gas.Can guarantee the burning of combustion chamber.
Obviously, too much when the oxygen supply of vaporizer 3, stalk will burn rapidly, the utilization that can not continue.Too low when the temperature of vaporizer, stalk will stop cracking, extinguishes even fully.Therefore, can adjust oxygen-supplying amount according to the combustion position of combustion chamber., after burning for some time, the clearence degree of stalk will reduce, and ash port 27 is also by silting, and it is inadequate only depending on unlatching soot door 17 to come supplemental oxygen, and can start blower fan 14 this moment, and amplify lower control valve 15, injects combustion air to vaporizer 3 by force.The wind-force that injects after the accumulation of the periphery of even fan housing 18 from around each wind hole 25 evenly enter vaporizer 3, make the burning uniformity in vaporizer 3.When the burning of combustion chamber 6 is normal, can suitably close blower fan 14, this moment, unnecessary wind namely entered combustion chamber 6 from upcast ventilation pipe 11, played combustion-supporting effect, can not cause waste.
The stove and accessory that the second embodiment: Fig. 7 introduces and the stove and accessory of the first embodiment are basic identical, difference is the middle part at body of heater, a cover doffer is equipped with in the position that is relative vaporizer 3, this doffer has a blanking bar 29 to cross vaporizer 3, the outer surface cover of blanking bar 29 has sleeve pipe 30, branched blanking pawl 31 is equipped with in the outside of sleeve pipe 30, and an end of blanking bar 29 stretches out body of heater 1, and a blanking handle 28 is housed.During work, at set intervals, shake blanking handle 28 by the people, can make the stalk in vaporizer 3 shake off ashes, increase porosity, be beneficial to even oxygen supply and stable decomposition.
The third embodiment: the stove and accessory of introducing as Fig. 8 Fig. 9 and the stove and accessory of the first embodiment are basic identical, difference is that lower air conduit 19 directly inserts in the following even fan housing 18 of vaporizer 3, the outer end of lower air conduit 16 is airtight, both sides and upside are respectively opened four wind holes 25, also can provide oxygen uniformly in vaporizer 3.
The stove and accessory of the 4th kind of embodiment: Figure 10 introduction and the structure of the third embodiment are basic identical, lower air conduit 19 directly inserts in the following even fan housing 18 of vaporizer 3, different is: lower air conduit 16 is divided into two breeches pipes 32, the outer end of two breeches pipes 32 is airtight, the outside and upside are respectively opened three wind holes 25, also can provide oxygen uniformly in vaporizer 3.
The 5th kind of embodiment: Figure 11, shown in Figure 12, body of heater are contained in cubical enclosure 33 the insides, make the body of heater top become platform for ease of cooking operation, and be moulded more attractive in appearance.
The 6th kind of embodiment: as shown in Figure 14 in Figure 13, at heat pipe 34 of the interior insertion of vaporizer 3, heat pipe 34 can be contained on blanking bar 29, is perhaps substituted by the blanking bar, and its outer end is exposed at outside body of heater 1, and is connected with temperature controller 35.Temperature controller 35 can be set two the temperature control points in up and down according to the burning-point of stalk, during lower than cracking temperature, temperature controller is controlled fan starting, makes simultaneously lower control valve 15 amplified flows when the temperature in vaporizer 3, temperature in vaporizer has reached high point, even blower fan cuts out or lower control valve 15 cuts out.Certainly, can set more temperature control point, lower control valve 15 is according to the size that needs by-pass cock in stove.
