Detailed description of the invention

A kind of furnace kiln structure, as Figure 1-3, including body of heater 10, the furnace chamber of body of heater 10 is divided into combustion chamber 11 and the air-inlet cavity 12 of upper and lower layout, the interlayer of separated combustion chamber 11 and air-inlet cavity 12 passes through near furnace bottom and air feed gap, described air-inlet cavity 12 inner circumferential is arranged at intervals with windbreak 13, and body of heater 10 sidewall between adjacent two windbreaks 13 offers air inlet 14.During use, by air inlet 14 to air-inlet cavity 12 zonal ventilation between each adjacent two windbreaks 13, so that air-inlet cavity 12 is evenly distributed with wind on the whole, it is ensured that the wind entered in combustion chamber 11 through interlayer is dispersed, and then improve the combustion uniformity of material.

As further preferred version: a side wall limit 131 of windbreak 13 reclines mutually with the inwall of body of heater 10, another side wall limit 132 of windbreak 13 extends gradually to the center near air-inlet cavity 12, as shown in Figure 2, the wind in air-inlet cavity 12 region between adjacent two windbreaks 13 is so made to flow up on the whole, ensure its correspondingly combustion chamber 11 region have distinguished and admirable enter, preferably, the overall profile of described body of heater 10 is cylindrically.

Preferably, as Figure 1-3, the outside of body of heater 10 is provided with airduct 20, the outlet and inlet port 21,22 of airduct 20 connects the air inlet 14 on wind regime and body of heater 10 respectively, and airduct 20 is provided with electromagnetic valve 30 to control the ventilation of blast pipe 20, to close pneumatic work on the pipeline of its air-out port 22, so can pass through to control the on-off action of electromagnetic valve 30, and then adjust the material combustion case in each region in combustion chamber 11.

Concrete scheme is, as shown in Figure 1, the interlayer of separated combustion chamber 11 and air-inlet cavity 12 includes brick layer 15, described brick layer 15 is piled up by two-layer square brick and is constituted and between adjacent square brick, gap is arranged, to ensure combustion chamber 11 and that air-inlet cavity 12 is separated meanwhile, it is capable to the material in combustor 11 is played a supporting role, certainly, as it was previously stated, in order to ensure that the wind energy in air-inlet cavity 12 enough flows in combustion chamber 11, described brick layer 15 must be available for wind gap and passes through.

Preferably, as shown in figs. 1 and 3, the interlayer of separated combustion chamber 11 and air-inlet cavity 12 also includes the coil pipe 16 being circulated through for cold water, coil pipe 16 is matched with the radial section of air-inlet cavity 12 by the wall top support of windbreak 13 and the card size of coil pipe 16, and described brick layer 15 is piled up in the card of coil pipe 16.Burning for rice hull ash, silicon dioxide in order to ensure burning gained meets the instructions for use of Downstream Market, the ignition temperature of preferred rice hull ash is controlled between 150-165 DEG C, therefore by the layout of coil pipe 16, so when in combustion chamber 11, the ignition temperature of material is beyond this scope, logical circulating water in coil pipe 16 can be passed through, to reduce the ignition temperature of rice hull ash.

Preferably, as Figure 1-3, the surface at air-out port 22 place of airduct 20 is provided with thermocouple 40, and the warming end of thermocouple 40 is inserted in the interlayer of combustion chamber 11 and air-inlet cavity 12 from the sidewall of body of heater 10.The warming end of thermocouple 40 is inserted in interlayer; so can play the effect of protection thermocouple 40; the corresponding interlayer temperature of air-inlet cavity 12 overlying regions between adjacent two windbreaks 13 can be detected again; this regional temperature can essentially show the ignition temperature in combustion chamber 11 region of correspondence indirectly; therefore the temperature in air-inlet cavity 12 region of correspondence can suitably be regulated according to the temperature sensor of each thermocouple 40, thus improving the uniformity of material burning further.

Further, as shown in Figure 1, described coil pipe 16 is made up of upper and lower two-layer pipeline, and the tube core direction of upper and lower two-layer pipeline is vertical, actual in observing, only illustrating the pipeline configuration of single layer coil tube 16 in Fig. 4, we can be understood as the arrangement states that the pipe level 90-degree rotation shown in Fig. 4 is other one layer of pipeline.Preferably, between described brick layer 15 and coil pipe 16, it is provided with fire brick layer 17, to play the effect of protection coil pipe 16；Fill out between described brick layer 15 and fire brick layer 17 and be provided with brickbat layer 18 so that brick layer 15 level is piled up.
