Raw second pyrolysis reaction.Present invention reduces the tar contents of fuel gas, improve the quality of fuel gas.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of biomass gasifying furnace of the present invention.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
As shown in Figure 1, the present invention provides a kind of biomass gasifying furnace, comprising: the furnace body 1 being vertically arranged comprising gasification
The lower section of the vaporizer is arranged in room 8, combustion chamber 3 and collection chamber 2, the combustion chamber 3, communicates with the vaporizer, described
The top of the vaporizer is arranged in collection chamber, communicates with the vaporizer；Second pyrolysis room is circumferentially positioned at the burning
Tar cracking catalyst is filled in the outside of room 3, the second pyrolysis room 5；Multiple air inlet pipe 6, one end of the air inlet pipe is along institute
The tangential direction for stating combustion chamber stretches to the combustion chamber, and the other end of the air inlet pipe, which is connected to, to be arranged outside furnace body
Combustion-supporting gas feedway, and multiple air inlet pipe are uniformly arranged relative to the combustion chamber, and the nozzle 7 of the air inlet pipe is flat
Mouthful shape, and the length direction of the nozzle of the air inlet pipe is axial parallel with the combustion chamber, the width of the nozzle for 0.3~
0.5cm；The outside of the furnace body is arranged in gas-guide tube 4, and one end is connected to the collection chamber, and other end connection is described secondary
Cracking room.
In the present invention, fuel gas containing tar enters collection chamber, and is entered in second pyrolysis room by gas-guide tube.Two secondary fissures
Solution room is circumferentially positioned at the outside of combustion chamber, inside fills tar cracking catalyst.Fuel gas containing tar is in second pyrolysis room
It is interior, by the heating for the indoor heat that burns, second pyrolysis reaction occurs under the catalytic action of tar cracking catalyst, thus
Reduce tar content.
Especially for the indoor heat of burning is made full use of, the present invention is provided with multiple air inlet pipe, one end of air inlet pipe
Be stretched to along the tangential direction of combustion chamber burning it is indoor, the other end of air inlet pipe, which is communicated to, is arranged in helping outside furnace body
On combustion gas body feeding, in this way, air inlet pipe will supply combustion-supporting gas to combustion chamber along tangential direction.And due to air inlet pipe
Caliber very little, only 0.3~0.5cm, can combustion chamber inner wall formed a combustion-supporting gas air film.Due to depositing for air film
, the combustion case near the inner wall of combustion chamber can be more preferable, and more sufficiently, and then keep the temperature near the inner wall of combustion chamber higher,
To keep the indoor temperature of second pyrolysis also higher, the indoor fuel gas containing tar of second pyrolysis is promoted sufficiently to react.
In order to promote the inside in combustion chamber to form uniform combustion-supporting gas air film, the nozzle of air inlet pipe is designed to flat mouth
Shape, and the width design of nozzle is 0.3~0.5cm.Uniform combustion-supporting gas air film can guarantee near wall in the combustion chamber
More evenly, i.e., the temperature near Inner Wall of Combustion Chamber also more evenly, and then guarantees the indoor second pyrolysis reaction of second pyrolysis for burning
Also uniformly occur.
