Abstract
The utility model relates to a negative-pressure gasifier. The negative-pressure gasifier is characterized in that: the gas outlet of the cavity between an inner gasifier body barrel (11) and an outer gasifier body barrel (12) is connected with the gas inlet of a speed-regulatable draught fan (5), so that negative pressure can be generated in the cavity, the carbon dioxide produced by biomass fuel (9) burning in the gasifier body and the biomass gas produced by high-temperature carbon are sucked into the cavity via a fire grate (10) when an ash cover (13) is closed, and then pass through an air distribution knob (3), which is adjusted, the sucked oxygen and the gas are mixed and enter a stove (7) via the speed-regulatable draught fan (5), valves (8) and a backfire preventer (6) to burn with the supplied air, or the gas burns with the distributed air when the air distribution knob (3) is closed. If explosion occurs in the cavity, an inverted cone type safety device (4) can spring up to release pressure; and a porous circular tube (1) uniformly collects the biomass gas in the upper part of the cavity. A spinning central-hole gasifier cover device (2) can ensure that the ignited biomass fuel (9) can uniformly burn towards the middle, steam and nitrogen upwardly escape from the central hole, tar returns into biomass and continues to burn, and thereby the discharge of the tar is reduced.
Description
Affiliated technical field
The utility model is specifically related to the living pledge gasification furnace field of generally promoting the use of in a kind of whole nation, is widely used in remote and energy free area, rural area.
Background technology
At present, domestic use be stalk gasifier, nothing more than composite gasification furnace, no blower fan gasification furnace, infrared gasification stove, heating type gasification furnace, downdraft gasification furnace etc.Principle is approaching, architectural difference, ubiquitous problem is: use inconvenient, raw material and the filler firing technique is difficult grasps, light a fire slow, igniting is slow, air feed is discontinuous, the furnace charge humidity is influenced, reinforced dying, reinforced filled with smoke, tar is unpleasant difficult, the slag difficulty is drawn, the charing fuel that does not burnout in addition is so the domestic stalk gasifier of generally promoting uses and is obstructed.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned ubiquitous problem, a kind of negative pressure gasification furnace to be provided.
A kind of negative pressure gasification furnace that provides is characterised in that: bucket 11 in the body of heater is set in the bucket 12 outside body of heater, the combustion gas escape pipe on bucket 12 tops connects air distribution knob 3 and back taper formula safety device 4 outside body of heater, and combustion gas escape pipe afterwards connects adjustable speed air-introduced machine 5 and valve 8 and fireproof tempering device 6 successively.Uniform porous endless tube 1 is installed on the top between the bucket 12 outside bucket 11 and the body of heater in body of heater; Place spinning mesopore bell device 2 on the biomass fuel 9 in body of heater in the bucket 11; Ash discharge port lid 13 is installed in the bottom of bucket 12 outside body of heater.
A kind of effect of negative pressure gasification furnace is simple in structure easy to operate, abundant, easy to use, raw material of aerogenesis and filler firing technique are easily grasped in the anaerobism burning, light a fire, light a fire soon, air feed is continuous, be not subjected to the furnace charge humidity influenced, part tar is handled in anaerobism preferably.
Description of drawings
Accompanying drawing is a kind of negative pressure gasification furnace schematic diagram.
Among the figure: bucket 11, the outer bucket 12 of body of heater, ash discharge port lid 13 in porous endless tube 1, spinning mesopore bell device 2, air distribution knob 3, back taper formula safety device 4, adjustable speed air-introduced machine 5, fireproof tempering device 6, cooking stove 7, valve 8, biomass fuel 9, fire grate 10, the body of heater.
The specific embodiment
Embodiment is described in further details the utility model below in conjunction with accompanying drawing, as shown in drawings: body of heater is inside and outside two-layer cylinder interlayer cavity body structure, light the biomass fuel 9 above the body of heater, send into power supply for adjustable speed air-introduced machine 5, and bucket 11 is connected with the air inlet of adjustable speed air-introduced machine 5 the cavity gas outlet between the bucket 12 outward with body of heater in the body of heater, make cavity produce negative pressure, under the situation of ash discharge port lid 13 sealings, carbon dioxide that body of heater internal combustion biomass fuel 9 produces and pyrocarbon generate combustion gas and are drawn into cavity through fire grate 10, during through air distribution knob 3 and back taper formula safety device 4, regulate oxygen that the big young pathbreaker of air distribution knob 3 sucks and mix with biological fuel gas and enter cooking stove 7 by adjustable speed air-introduced machine 5 and valve 8 and fireproof tempering device 6 and carry out the air-feeding type burning; Also can close air distribution knob 3 directly enters cooking stove 7 to biological fuel gas by adjustable speed air-introduced machine 5 and valve 8 and fireproof tempering device 6 and carries out the air distributing type burning.If fire in the cavity, then the back taper check valve on the back taper formula safety device 4 is upspring and release; Fireproof tempering device 6 can stop cooking stove flame to turn back in adjustable speed air-introduced machine 5 and the cavity to fire.Porous endless tube 1 is the biological fuel gas of collection chamber internal upper part evenly.Spinning mesopore bell device 2 can make the biomass fuel of lighting 9 evenly to the middle part burning, and steam and nitrogen are upwards overflowed from mesopore, and tar turns back in the living beings and burns away, and reduces the tar discharging.This negative pressure gasification furnace is applicable to air distributing type cooking stove and air-feeding type cooking stove.
