Abstract
The utility model discloses a biomass gasification heat supply unit, including the gasifier, cyclone fires burning furnace, and the draught fan, gasifier furnace hearth cross section is the rectangle, and the gasifier below is installed out the ash and is stirred the cage, and the periphery that fires burning furnace has the circulating water jacket, fires burning chamber afterbody of burning furnace and connects the tobacco pipe, and the tobacco pipe export has the draught fan to be linked together. The combustion chamber front portion has a throat and falls into combustion chamber and postcombustion chamber before calabash form, the utility model overcomes present gasification unit adopts the malleation air blast, can not continuous feeding, can only intermittent operation, and the gas production is shortcoming such as little, founds in utilizing agricultural resources, adopts straw, corncob etc. as the raw materials, and the gas production is big, can supply gas burning in succession, for rural, cities and towns or district central heating, also can be used to warmhouse booth vegetable planting, breed etc. in winter.
Description
Technical field
The utility model relates to a kind of fixed bed gasification heat supply unit, a kind of novel biomass gasifying heat supply unit of more specifically saying so.
Background technology
Make full use of crop genetic resources such as low-calorie stalk, firewood, corn cob, save coal, wet goods Nonrenewable energy resources, protect environment, meet the energy and the Environmental policy of China.The main component of stalk is that carbon, hydrogen, oxygen etc. are elementary composition, stalk is pulverized through hay cutter, also can be as firewood, corn cob raw coal etc. without processing, directly enter vapourizing furnace, enter in the gasification producer by self-conveyor feed, redox reaction takes place in Controlled burning under anoxic condition, each element is reformulated inflammable gass such as carbon monoxide, hydrogen, methane by thermo-cracking, the realization energy is changed to gasiform by solid-state.But present gasification unit all is to adopt the malleation air blast, can not continuously feeding, can only intermittent operation, and be not suitable for that air demand is big, air feed burning continuously, be the occasion of cities and towns or sub-district central heating, heating.
Summary of the invention
The purpose of this utility model provides a kind of gasifying biomass heat supply unit of negative-pressure firing, can continuous production coal gas, and also pollution-free, gas leakage can not take place, air demand is big, is embodied as cities and towns or sub-district central heating, heating.
The technical solution of the utility model is as follows:
Gasifying biomass heat supply unit, include vapourizing furnace, tornado dust collector, roasting kiln, and induced draft fan, it is characterized in that: described vapourizing furnace burner hearth transverse section is long strip shape or rectangle or square, the vapourizing furnace below is equipped with ash discharge and stirs cage, and the ash output hole that ash discharge stirs cage immerses under the liquid level in pond, and the periphery of roasting kiln has the recirculated water chuck, the combustor tail smoke collecting tube of roasting kiln, the smoke pipe outlet has induced draft fan to be connected.
There is a reducing front portion, combustion chamber and is divided into preceding combustion chamber and after-burner, and preceding combustion chamber is the cucurbit shape, and preceding outer wall of combustion chamber is filled with refractory materials.
Vapourizing furnace, tornado dust collector all have air jacket and mutual UNICOM outward, and air enters roasting kiln through air jacket and pipeline.
Helical feeder is installed on the vapourizing furnace.
Long strip shape of the present utility model, rectangle furnace cross section, the air of air inlet port sprays to burner hearth central vertical face from perisporium, in theory, no matter burner hearth how long, air dielectric and biomass material can both uniform mixing, solved the uniform mixing difficult problem of air and biomass in the large vol fixed-bed type biomass gasifying furnace, vapourizing furnace can be worked under negative pressure state simultaneously, gas leakage can not take place, guaranteed production safety,, realized serialization production by the continuous charging of helical feeder, the air feed single-machine capacity increases, and unit cost reduces.
Rotate ash discharge and stir cage, at this moment ashes advance along screw-blade, fall into the pond, and ash output hole extend under the water surface, makes coal gas can not overflow, and ashes are lighter, float on the surface, and can drag for away, do not influence the vapourizing furnace ordinary production when removing coal ash.
After the coal gas of vapourizing furnace output is handled through the tornado dust collector rough purification, directly enter roasting kiln and carry out the air distribution burning, produce high-temperature flue gas, heating cycle water is realized continuous heat supply.There is a reducing front portion, combustion chamber of roasting kiln and is divided into preceding combustion chamber and after-burner, and preceding combustion chamber is the cucurbit shape, and outer wall is filled with refractory materials, make that coal gas and air therein can thorough mixing, fully burning, burning room temp height, when gas supply has fluctuation, guarantee to catch fire automatically.
It is raw material that the utility model can adopt stalk, corn cob etc., is based on utilizing agricultural resource, can be widely used in the central heating or the hot water service of rural area or small town citizen, also can be used for vegetables in greenhouse booth plantation, breed in winter etc.
