Abstract
A biomass fluidized bed gasifier of multi-jet gas distribution uses a vertical furnace, which is divided into dreg segment, water seal segment, gas distribution segment, feeding segment, gradually spreading segment, and upper straight segment. The utility model is characterized in that the gas distribution segment is set as the inverted bell mouth segment with small mouth being upside and big one downside. The gas distribution mouth is evenly distributed in the sidewall and a spraying pipe passes through the sidewall of the furnace, whose spraying mouth is in the center of the gas distribution segment to form the side entry of the multi-strands of gasification agent and the structure of center spraying.
Description
Technical field
The utility model relates to gasifying biomass equipment, a kind of biomass fluidized bed gasification furnace of more specifically saying so.
Background technology
Utilize biomass such as low-calorie crop stalk, forestry waste, in vapourizing furnace by hot physical change and chemical reaction, produce inflammable gass such as carbon monoxide, hydrogen, methane,, meet the energy and the environmental protection policy of China for combustion heat supplying or as the chemical industry synthetic raw gas.At present, biomass fluidized bed gasification furnace on the market all develops from traditional fluidized-bed, adopt air distribution plate, but the setting of air distribution plate has brought a lot of problems to operation, must be lower than ash fusion point 50-100 degree such as service temperature, otherwise easily cause air distribution plate to stop up, destroy stream and change very much, and air distribution plate cleaning difficulty.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of multiple jets distribution biomass fluidized bed gasification furnace being provided.Advance with the central-injection structure to replace air distribution plate with the multiply side,, reduce the tar content in the combustion gas to improve service temperature, to improve the charcoal transformation efficiency.
The utility model technical solution problem adopts following technical scheme.
The utility model adopts vertical body of heater, and vertical body of heater is followed successively by sediment section, aqua seal section, gas distribution section, feed zone, divergent segment and upper straight section from bottom to top.
Constructional feature of the present utility model be gas distribution section be set to osculum last, big mouthful under inverted oared segrne pii, air distribution port is evenly distributed on its sidewall, other has spray tube to run through sidewall of the furnace body, it sprays the mouth of pipe and is on the central position of gas distribution section, and the multiply side that forms vaporized chemical is advanced and the central-injection structure.
Constructional feature of the present utility model also is in the sidewall of gas distribution section the annular steam chuck to be set, and air distribution port is evenly distributed on the inner side-wall of annular steam chuck.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is provided with the multiply side and advances and the central-injection structure, no longer needs air distribution plate, has avoided being difficult to associated problem such as cleaning because of what use that air distribution plate brought.
2, the utility model adopts the multiply side to advance mode with central-injection, can guarantee that air inlet is even.
3, the utility model is provided with inverted hydraucone and water seal, can effectively avoid the dross accumulated slag, has reduced the workload of maintenance of the equipment, guarantees that the air port is unimpeded.
Description of drawings
Accompanying drawing is the utility model structural representation.
Number in the figure: 1 sediment section, 2 aqua seal sections, 3 gas distribution sections, 4 feed zones, 5 divergent segments, 6 upper straight sections, 7 spray tubes, 8 spiral tapping machine structures, 9 screw propulsion feed mechanisms, 10 venting ports, 11 annular steam chucks.
Below pass through embodiment, and in conjunction with the accompanying drawings the utility model be further described:
Embodiment
Referring to accompanying drawing, adopt vertical body of heater, vertical body of heater is followed successively by sediment section 1, aqua seal section 2, gas distribution section 3, feed zone 4, divergent segment 5 and upper straight section 6 from bottom to top, and venting port 10 is arranged on the top of upper straight section 6.
As shown in the figure, in the bottom of body of heater, be positioned on the sediment section 1, spiral tapping machine structure 8 is set, be positioned on the feed zone 4, screw propulsion feed mechanism 9 is set, it is big that 5 ends of divergent segment are young, suitable for reading, by spiral tapping machine structure 8 and screw propulsion feed mechanism 9 are set, realize continuously uninterrupted production.
In the present embodiment, with gas distribution section 3 be set to osculum last, big mouthful under inverted oared segrne pii, air distribution port is evenly distributed on its sidewall, other has spray tube 7 to run through sidewall of the furnace body, it sprays the mouth of pipe and is on the central position of gas distribution section 3, this structure formation has formed the multiply side of vaporized chemical to be advanced and the central-injection structure, no longer needs to be provided with air distribution plate.
In concrete the enforcement, in the sidewall of gas distribution section 3, annular steam chuck 11 is set, air distribution port is evenly distributed on the inner side-wall of annular steam chuck 11.
Low heat value farm crop such as straw, biomass such as forestry waste are sent in the body of heater by screw propulsion feed mechanism 9, vaporized chemical advances with central-injection to send in the stove by the multiply side, vaporized chemical and biomass are after mix the feed zone position, being the jet flow state enters in the divergent segment, be the reaction of fluidization generating gasification at the divergent segment internal diffusion, produce carbon monoxide, hydrogen, combustible gases such as methane, and further rise and in upper straight section, finish gas solid separation, part charcoal ash is discharged in venting port 10 with combustible gas, and can further separate by cyclonic separator, the bulk lime-ash directly falls, and in the bottom of furnace body sediment section, discharge through spiral tapping machine structure 8, the setting of water seal also makes the lime-ash that falls be lowered the temperature.
