Accompanying drawing explanation
Fig. 1 is the structural representation of biomass gasifying furnace of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art's reference
Description word can be implemented according to this.
As it is shown in figure 1, the present invention provides a kind of biomass gasifying furnace, including: the body of heater 1 being vertically arranged,
It includes that vaporizer 8, combustor 3 and collection chamber 2, described combustor 3 are arranged under described vaporizer
Side, communicates with described vaporizer, and described collection chamber is arranged on the top of described vaporizer, with described gasification
Room communicates；Second pyrolysis room, it is circumferentially positioned at the outside of described combustor 3, described second pyrolysis room
5 fill tar cracking catalyst；Multiple air inlet pipe 6, one end of described air inlet pipe is cut along described combustor
Line direction stretches to described combustion chamber, and the other end of described air inlet pipe is communicated to be arranged on outside body of heater
Combustion-supporting gas feedway, and multiple air inlet pipe is uniformly arranged relative to described combustor, described air inlet
The mouth of pipe 7 of pipe is flat mouth shape, and the length direction of the mouth of pipe of described air inlet pipe and described combustor is axial
Parallel, the width of the described mouth of pipe is 0.3～0.5cm；Airway 4, it is arranged on the outside of described body of heater,
One end is communicated to described collection chamber, and the other end connects described second pyrolysis room.
In the present invention, enter collection chamber containing tar fuel gas, and enter second pyrolysis room by airway
In.Second pyrolysis room is circumferentially positioned at the outside of combustor, fills tar cracking catalyst in it.Containing Jiao
Oil fuel gas is indoor at second pyrolysis, by heating of the heat in combustor, is catalyzed at coke tar cracking
There is second pyrolysis reaction under the catalytic action of agent, thus reduce tar content.
Especially for the heat made full use of in combustor, the present invention is provided with multiple air inlet pipe, air inlet
One end of pipe is to stretch in combustor along the tangential direction of combustor, the other end connection of air inlet pipe
To being arranged on the combustion-supporting gas feedway outside body of heater, so, air inlet pipe will along tangential direction to
Combustor supply combustion-supporting gas.And owing to the caliber of air inlet pipe is the least, only 0.3～0.5cm, can be in combustion
The inwall burning room forms the air film of a combustion-supporting gas.Due to the existence of air film, near the inwall of combustor
Combustion case more preferably more fully, and then the temperature near the inwall of combustor can be made higher so that
The temperature of second pyrolysis indoor is the highest, and the fuel gas containing tar promoting second pyrolysis indoor fully reacts.
In order to promote to be internally formed uniform combustion-supporting gas air film at combustor, the mouth of pipe of air inlet pipe is set
Count into flat mouth shape, and the width design of the mouth of pipe is 0.3～0.5cm.Uniform combustion-supporting gas air film can ensure that
Evenly, i.e. the temperature near Inner Wall of Combustion Chamber is the most evenly in burning near Inner Wall of Combustion Chamber, and then
Ensure that the second pyrolysis reaction of second pyrolysis indoor the most uniformly occurs.
The present invention takes full advantage of existing thermal source, improves the utilization ratio to the energy.
Preferably, in described biomass gasifying furnace, described tar cracking catalyst is limestone and carbon
Acid magnesium.In this embodiment, burning indoor temperature can select 800～1000 DEG C.
