Description
Technical field
The present invention relates to the used device of compacting material in a kind of biomass gasifying furnace, is a kind of at constant-pressure material compacting device of biomass fixed-bed gasification furnace specifically.
Background technology
At present, disclosed various biomass gasifying furnaces, its inside is generally partly formed by drying layer, pyrolytic reaction layer, combustion oxidation layer, reducing zone and grey chamber etc.; Though concrete structure is had nothing in common with each other, all there is following deficiency in they: no material compacting apparatus in the burner hearth, and the degree of compactness of bed depth and material is inhomogeneous in the gasifier operation process; Same vapourizing furnace applicable raw materials is single; Be prone to cause problems such as the coking of fire box temperature overtemperature, the bed of material burn, quick-fried stove, influence the just operation of stove and have potential safety hazard, need artificial long-time on duty poking fire; Special in the less raw material of tap density, situation is particularly outstanding.
Summary of the invention
The present invention is in order to overcome the problem that existing biomass gasifying furnace in use runs into; A kind of constant-pressure material compacting device of biomass fixed-bed gasification furnace has been proposed; It is installed on the vapourizing furnace; Can make vapourizing furnace have flexibility widely, keep the degree of compactness uniformity of bed depth and material, avoid phenomenons such as the bed of material burns, overtemperature coking, quick-fried stove to take place for the biomass material of different stacking densities.
The technical solution adopted for the present invention to solve the technical problems is: this constant-pressure material compacting device of biomass fixed-bed gasification furnace mainly is made up of reducing motor, electric machine support, coupling band, transmission shaft, binder blade turning axle, pressure regulating sleeve, binder spring, push rod, sleeve contiguous block, binder blade; Whole device is installed in the top of gasification furnace central position, and its rotation center is coaxial with the vapourizing furnace axial line, is fixed on the furnace roof through electric machine support, and in the gasifier operation process, controlling level must be higher than the binder blades height, and compacting apparatus must rotate all the time; Reducing motor is connected rotation through coupling band with transmission shaft, transmission shaft and binder blade turning axle be through being threaded, and with jackscrew both is fixed; Binder blade turning axle top is provided with the pressure regulating sleeve, and the pressure regulating sleeve is fixed on the binder blade turning axle through jackscrew through the threaded adjusting axial location; Binder blade turning axle bottom is provided with the pressure floating bushing, and the binder spring is installed on the pressure floating bushing; The sleeve contiguous block is fixed on the binder blade turning axle through key and nut; The binder blade pass is crossed push rod and is fixed on the sleeve contiguous block; Said push rod, both as the locating element of binder blade axial and circumferential on the sleeve contiguous block, the push rod as the pressure floating bushing used again; When reducing motor rotates; Through binder blade rotation produce to the material axial force with the downward compacting of material, after material density reached certain degree of compactness, the binder blade made the angle of itself and horizontal plane diminish because of the reactive force of material increases; Axle pressure to material becomes big; Maximum when being up to the standard the position, when material moved down because of gasification consumes, the effect that the binder blade pass is crossed the binder spring became greatly its angle with horizontal plane; Axle pressure to material diminishes; The effect binder blade through the binder spring and the angle of horizontal plane change in more among a small circle at one, guarantee that the binder blade to material constant axle pressure almost, makes vapourizing furnace material compacting degree in gasification stable.
The invention has the beneficial effects as follows: this constant-pressure material compacting device of biomass fixed-bed gasification furnace can require to guarantee needed material compacting degree according to gasifying process for the material of different stacking densities; Avoid phenomenons such as the bed of material burns, overtemperature coking, quick-fried stove to take place, guarantee the vapourizing furnace safe and stable operation.The binder level controlling system can be realized fully automatic feeding, need not long-time artificial on duty.For with a kind of vapourizing furnace applicable to multiple biomass material, raw material is had flexibility widely.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Accompanying drawing is the structure principle chart of this constant-pressure material compacting device of biomass fixed-bed gasification furnace.
