Abstract
The utility model relates to a partition board type internal circulation fluidized bed gasification furnace, which is a device using biologic substances (such as straw and wood cutting) as raw materials to produce fuel gas, wherein a partition board is arranged inside a furnace hearth to form two reaction zones; during using process, the air input pressure of an air distribution board at the two sides of the partition board is adjusted to form a pressure difference; the material can be circularly flowed in the two reaction zones, a plurality of gasification reactions of the materials are conducted; therefore, the gasification rate is increased.
Description
The utility model is announced is be that raw material gasifies with biomass (as straw, wood chip etc.), thereby produces the equipment of inflammable gas, specifically is a kind of fluidized-bed gasification furnace that has dividing plate, makes two reaction zones of formation in the body of heater.
At present, employed vapourizing furnace in production reality is to be made of body of heater and the wind distribution plate in its underpart.Its principle of work is that quantitative air is sent into burner hearth from the wind distribution plate, by regulating blast, make the biological particles that is ground into certain particle size in burner hearth, be fluidized, gas equals its gravity for the buoyancy of solid particulate, make biological particles under the oxygen deprivation condition, carry out incomplete combustion, thereby produce inflammable gass such as carbon monoxide, methane, hydrogen.Because do not have pressure difference in the burner hearth of this kind equipment, particle is suspended state, often just not overflowing body of heater before the complete reaction, so vaporization rate is low, combustion gas output is not high.So this equipment is not really desirable.
The purpose of this utility model provides a kind of material particles that makes and enter gasification zone, reaction fluidized-bed gasification furnace more completely repeatedly in body of heater.To improve vaporization rate, the more combustion gas of output.
The utility model is achieved by the following technical solution, and its structure as shown in drawings.One dividing plate (2) is arranged in body of heater (1).The rear and front end of dividing plate is separately fixed at the front and rear of burner hearth, makes burner hearth form two reaction zones.One wind distribution plate (3) is arranged in the body of heater bottom.Wind distribution plate and gas blower are complementary.Method of work of the present utility model is identical with currently available products.Just regulate the blast of dividing plate both sides wind distribution plate in use, just make both sides pressure different, so just pressure difference occurs in the dividing plate both sides, the biomass material particle flows at two reaction zone internal recycle that are divided into by dividing plate under action of pressure.Thereby make first unreacted completely material particles can in two reaction zones, repeatedly react, make material not overflow body of heater before the complete reaction.Improved vaporization rate.
The utility model is simple in structure, and is reasonable in design, just sets up a dividing plate in existing burner hearth, makes burner hearth form two reaction zones.Make the material complete reaction, improved vaporization rate.
Accompanying drawing is the utility model structure iron

The utility model is that the metal sheet welding is made.Dividing plate refractory materials system, wind distribution plate are universal component, with reference to this specification sheets and accompanying drawing, can reproduce this product by each professional known technology processing system.
Claims (1)
- The inner circulation fluidized bed gasification furnace of iris type is made of body of heater (1) and the wind distribution plate (3) in its underpart, it is characterized in that a dividing plate (2) is arranged in the body of heater (1), and the dividing plate two ends are separately fixed at the front and rear part of burner hearth.
