The present invention is by above-mentioned specific design, have advantages of that compact conformation, body of heater high temperature resistance long-play are accessible, high efficiency catalysis wood tar, thermal loss is low, efficiency of combustion is high, safe and reliable to operation.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present invention is described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1, the present invention includes body of heater 1, body of heater 1 adopts refractory ceramics to condense, the hypomere of body of heater 1 is carbonizing chamber 2, the epimere of body of heater 1 is catalytic combustor 3, the bottom of carbonizing chamber 2 is provided with fire grate 4, offer bocca 5 on the catalytic combustor 3, the center of fire grate 4 is fixed in the rotating shaft 7 that is driven by motor 6, periphery at body of heater 1 forms the cooling wind-guiding road, cooling wind-guiding road periphery coats high-temperature-resistant thermal-insulation cotton 17, middle part, cooling wind-guiding road is separated into independently two sections of relative closure by air baffle 9, and hypomere cooling wind-guiding road 8A is communicated with fire grate 4 by wind conveying pipe 10, and epimere cooling wind-guiding road 8B is communicated with catalytic combustor 3 by the qi of chong channel ascending adversely hole 11 of offering on catalytic combustor 3 outer walls, qi of chong channel ascending adversely hole 11 can a plurality ofly arrange, and tangentially is distributed on catalytic combustor 3 outer walls.The distinguished and admirable epimere cooling wind-guiding road 8B upper end that rotates into of air baffle 9 tops, tangentially blow by qi of chong channel ascending adversely hole 11 and to inject catalytic combustor 3 and carry out efficient oxidation catalysis, the distinguished and admirable of air baffle 9 belows rotates into hypomere cooling wind-guiding road 8A and wind conveying pipe 10, and enters carbonizing chamber 2 burning carbonization bio-fuels generation carbon monoxide.Distinguished and admirablely can cool off body of heater 1, make body of heater 1 keep the high-temperature and durable operation but temperature can not continue to rise; Part heat with body of heater 1 passes to oxygen-containing gas by heat exchange simultaneously, and oxygen-containing gas becomes high temperature by normal temperature, and the oxygenous physical efficiency of high temperature makes the catalysis of fuel accelerated oxidation, simultaneously wood tar is had the effect of efficient catalytic.The air outlet end of wind conveying pipe 10 forms defeated wind seat 12, and rotating shaft 7 is bearing in the defeated wind seat 12.The bottom of fire grate 4 has the cooling fin 13 of extension, and cooling fin 13 can be arranged on the whole one-tenth of the periphery tubbiness of fire grate 4, and to solve the Air Leakage of fire grate 4 peripheries, cooling fin 13 immerses and is arranged in the water tank 14 of fire grate 4 belows, and water tank 14 band ramp designs make things convenient for deashing.Immerse cooling fin 13 in the water tank 14 and can effectively reduce the temperature of fire grate 4, make the fire grate 4 can high temperature deformation, prolonged the service life of fire grate 4.Wind conveying pipe 10 passes water tank 14, and a side of water tank 14 is communicated with water-level gauge 15, the convenient water level of observing, and the bottom of water tank 14 is provided with slag notch 16.The course of work of the present invention is: first granular pattern or broken foam type biomass fuel are put into hopper, send in the stove on the fire grate 4 by screw charger 18, fire grate 4 rotation under motor 6 drives, fuel is evenly distributed at fire grate 4, improve efficiency of combustion, biomass fuel mixes by the supply of a small amount of band carrier of oxygen, carry out first coal at carbonizing chamber 2, produce CO gas, after rising, carbon monoxide carries out the efficient mixed high-efficient burning of secondary with the high temperate zone carrier of oxygen of compressing into from qi of chong channel ascending adversely hole 11 at catalytic combustor 3, the efficient catalytic wood tar becomes heat energy simultaneously, forms thermal-flame spirt heat-needing facility device inner, reaches efficient heat production utilization.In order to reduce the dust in the flame, body of heater 1 interior employing pressure combustion, the pressure of top bocca 5 is high, and body of heater 1 internal pressure in below is low, and thermal current is lighter than dust with the thermal-flame quality, force upwards ejection of the lighter, severe one sinks, and drops in the water tank 14 of fire grate 4 belows, and heavy ash is cleared out by the slag notch 16 of water tank 14, hot gas flame is purer, and heat transference efficiency is higher.The present invention can be applied directly to industry, agricultural, manufacturing industry, service trade, educational business, health industry, such as: steam boiler, hot-water boiler, drying oven, heat transfer oil heat carrier boiler, smelting furnace, annealing furnace etc.Above-described embodiment only is that the preferred embodiment to rotary type fire grate burner with high efficiency of the present invention is described; be not that design and the scope of inventing limited; under the prerequisite that does not break away from the present invention program; various external form modification and improvement that those skilled in the art make technical scheme of the present invention all should fall into the protection domain of rotary type fire grate burner with high efficiency of the present invention.
