Description of drawings
Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment
Central idea of the present utility model is by the air channel of special distribution is set, and makes stalk briquette finish controlled burning or fully burning under the various conditions, to guarantee the efficiency of combustion of stalk briquette, improves dependability and flexibility.
The utility model will be further described below in conjunction with accompanying drawing 1:
Stalk briquette direct-combustion furnace described in the utility model comprises body of heater 1, support body 3, fire-resistant boiler clothing 4, ash output box 18, cyclone disk 13, wind-proof circle 6, the cap 8 of igniting, air blast 12, blast pipe 15 and air door 11.
Support body 3 is arranged in the furnace chamber of body of heater 1, and support body 3 is made by metal material, is used for supporting stalk briquette, combustion zone and lower ash output district in the formation.The bottom of support body 3 is discoid, and the edge of discoid support body is embedded in the inwall of body of heater 1, thereby cavity is divided into the upper and lower furnace chamber of relative sealing.Wherein, the middle part of discoid support body is provided with fire grate 20, and fire grate 20 is communicated with upper and lower furnace chamber as ash hole, and the top of discoid support body is provided with tubular supporter 2, supporter cavity 21 is corresponding with fire grate 20, and supporter cavity 21 uses as the combustion zone of stalk briquette.For forming effective insulation, effect of heat insulation, leave annular passage 9 between supporter outer wall and inboard wall of furnace body, annular passage 9 is wrapped on the supporter outer wall, makes the combustion zone form a relatively independent space in that body of heater 1 is interior, reduce heat energy loss, improved heat utilization rate.For guaranteeing the durability of supporter 2, in supporter cavity 21, also be nested with fire-resistant boiler clothing 4, the top of fire-resistant boiler clothing 4 is concordant with the top of supporter 2.Ash output box 18 is arranged in lower furnace chamber, and ash output box 18 is corresponding with fire grate 20 positions, after the grey piece that leaks down from fire grate 20 is fallen into ash output box 18, can take out from body of heater 1 easily, drain.
Body of heater 1 is a cylinder, be provided with the air outlet 14 that is communicated with upper furnace chamber at the upper end of body of heater 1 sidewall, the middle part of body of heater 1 and bottom are respectively equipped with enterprising air port 16 and lower air inlet 19, and enterprising air port 16 is communicated with the annular passage 9 of upper furnace chamber, and lower air inlet 19 is communicated with lower furnace chamber.Air blast 12 is communicated with upper and lower air inlet 16,19 respectively by blast pipe 15, for effectively controlling air intake passage, also is provided with air door 11 on blast pipe 15, and air door 11 is on the air inlet pipeline between air blast 12 and the lower air inlet 19.
For combustion process is carried out under a state that relatively seals, improve the efficiency of combustion of stalk briquette, the flashback performance of performance stalk briquette also is pressed with cyclone disk 13 at the top of furnace chamber inner supporting body 2.Cyclone disk 13 is an inverted open circles stage body with central through hole 17, and the hole wall of central through hole 17 seals the hollow round table intracoelomic cavity.The bottom support of cyclone disk 13 is at the top of fire-resistant boiler clothing 4 and supporter 2, the inwall close contact of the side top of cyclone disk 13 and body of heater 1, thus the upper furnace chamber of cyclone disk 13 belows is sealed relatively.Because cyclone disk 13 be round table-like, its side is corresponding to the top of annular passage 9, thereby annular passage 9 is sealed.The side of cyclone disk 13 is provided with equally distributed a plurality of wind hole 5, and wind hole 5 is communicated with annular passage 9 with the hollow round table intracoelomic cavity, so that the wind energy that is entered by enterprising air port 16 enters into the open circles stage body enough smoothly.For making wind energy enter smoothly combustion zone in the fire-resistant boiler clothing 4, also be provided with a plurality of air inducing hole 10 that is communicated with and distributes ringwise with the hollow round table intracoelomic cavity in the bottom surface of cyclone disk 13, be helical arrangement between a plurality of air inducing hole 10, the bottom surface outlet in air inducing hole 10 slopes inwardly and is relative with the combustion zone in the fire-resistant boiler clothing 4, after the wind of sending into is blown into the top, combustion zone with helical form, for the combustion zone provides oxygen.For further improving efficiency of combustion, on the hole wall of central through hole 17, also be provided with a plurality of equally distributed wind holes 7 of crossing, cross wind hole 7 central through hole 17 is communicated with the hollow round table intracoelomic cavity, make the wind energy of sending into directly enter into central through hole 17 by crossing wind hole 7.
For further improving the flexibility of using, the burning of guiding stalk briquette also is covered with the cap 8 of igniting on the central through hole 17 of cyclone disk 13.The cap 8 of igniting is a cap body, and cap body bottom surface is provided with through hole, and the cap 8 of igniting can further upwards guide the flare in the central through hole 17 and gather, and the burning things which may cause a fire disaster utilization rate is further improved.
For preventing that air outlet 14 air draft processes from causing energy loss, around the cap 8 of igniting, also be provided with wind-proof circle 6, wind-proof circle 6 is a circle body, and wind-proof circle 6 is put in the top of cyclone disk 13, and wind-proof circle 6 tops and body of heater 1 end face left cigarette channel.
During use, the stalk briquette that ignites is placed on the bottom fire grate 20 of support body 3, and fire-resistant boiler clothing 4 can effectively protect the supporter 2 on the support body 3 directly not contact with the stalk briquette of burning.When needs high temperature direct combustion, open air blast 12 and air door 11, wind is blown into from enterprising air port 16 and lower air inlet 19 respectively by blast pipe 15, and the wind that lower air inlet 19 is blown into directly runs through whole combustion zone from bottom to top, for stalk briquette provides sufficient oxygen, guarantee that sufficient combustion carries out.The wind that is blown into by enterprising air port 16 is behind annular passage 9, enter the inner chamber of cyclone disk 13 by wind hole 5, then, part wind is blown into the top, combustion zone in a spiral manner through air inducing hole 10, making does not have clean-burning volatilization gas in the second-time burning of top, combustion zone in the combustion zone, guaranteed combustion process, simultaneously, another part wind directly is blown in the central through hole 17 by crossing wind hole 7, interior to there not being clean-burning gas to carry out three burnings at central through hole 17, guaranteed that combustion process fully carries out, prevented the generation of combustion process black smoke phenomenon.At last, combustion flame the cap 8 of igniting gather with guiding function under, upwards scurry out from the bottom through-hole of the cap 8 of igniting, and under the guiding of air outlet 14 and wind-proof circle 6 to around shed, thereby finish heating to body of heater top kitchen range, guaranteed the Fast Heating process.And when combustion process needs gasification, and combustion, close air door 11, the wind that air blast 12 is blown into can only enter the combustion zone by enterprising air port 16, at this moment, stalk briquette burns under insufficient condition in the combustion zone, and then the stalk briquette rear generation fuel gas that can at first gasify carries out mixed combustion at the top, combustion zone with the air of sending into, after central through hole 17 interior second-time burnings, drawn by the cap 8 of igniting at last, thereby finish combustion process under insufficient condition.Lime-ash or grey piece that above-mentioned combustion process produces then drain in the ash output box 18 by fire grate 20, and taking-up ash output box 18 is outwelled lime-ash and got final product, and greatly facilitates use procedure, and so far, whole combustion process is finished.
