Detailed description of the invention
Fig. 1 is the structural schematic diagram of the biomass gasifying furnace of cleavable tar 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 of cleavable tar, comprising: the furnace body being vertically arranged
1 comprising the lower section of the vaporizer is arranged in vaporizer 8, combustion chamber 3 and collection chamber 2, the combustion chamber 3, with the gasification
Room communicates, and the top of the vaporizer is arranged in the collection chamber, communicates with the vaporizer；Second pyrolysis room surround and sets
The outside in the combustion chamber 3 is set, tar cracking catalyst is filled in the second pyrolysis room 5；Loop draught pipe 9 surround and sets
The outside in the second pyrolysis room is set, and the inner sidewall of the loop draught pipe is by the lateral wall of the second pyrolysis room
A part is constituted, be provided with a plurality of air holes 10 on the inner sidewall of the loop draught pipe, and multiple stomatas 10 are unevenly distributed
Even, the duct direction of two neighboring stomata is not identical, so that the airflow direction for spraying two neighboring stomata is different, the annular
Snorkel is connected to a high temperature air feedway；Multiple air inlet pipe 6, one end cutting along the combustion chamber of the air inlet pipe
Line direction stretches to the combustion chamber, and the other end of the air inlet pipe is connected to the combustion-supporting gas being arranged in outside furnace body and supplies
To device, and multiple air inlet pipe are uniformly arranged relative to the combustion chamber, and the nozzle 7 of the air inlet pipe is flat mouth shape, and described
The length direction of the nozzle of air inlet pipe is axial parallel with the combustion chamber, and the width of the nozzle is 0.3~0.5cm；Air guide
The outside of the furnace body is arranged in pipe 4, and one end is connected to the collection chamber, and the other end is connected to the second pyrolysis 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.
Gas cell distribution on loop draught pipe is uneven, and the duct direction of two neighboring stomata is not identical, so that
The airflow direction that two neighboring stomata sprays is not also identical, and what the air-flow of these different directions can disturb a small range can containing tar
The flow path of combustion gas body, so that the inside of the fuel gas containing tar forms vortex, to promote in fuel gas containing tar
Tar ingredients are constantly contacted with tar cracking catalyst, and then accelerate the lysis efficiency of tar.
It is highly useful when gasification furnace stops to improve lysis efficiency.In general, if gasification furnace production terminates, in combustion chamber
Just no longer there is combustible substance, then the temperature of combustion chamber can gradually decrease, and finally not be able to satisfy second pyrolysis room to temperature
The requirement of degree.And within a period of time that gasification furnace stops production, it still suffers from fuel gas containing tar and is gradually arranged out of furnace body
Out, it can be removed to guarantee the tar in this last part fuel gas containing tar also, it is necessary in chamber temperature
Be reduced to it is undesirable before, the processing to the fuel gas containing tar of this last part is completed in second pyrolysis room.
The present invention improves the lysis efficiency of tar in fuel gas containing tar, therefore, is reduced in chamber temperature undesirable
Before, the processing to last part fuel gas containing tar can be completed.
Stomata number in the number of loop draught pipe and each loop draught pipe, which can according to need, to be adjusted.
The present invention takes full advantage of existing heat source, improves the utilization efficiency to the energy.
Preferably, in the biomass gasifying furnace of the cleavable tar, the tar cracking catalyst is lime stone
And magnesium carbonate.In this embodiment, burning room temperature can choose 800~1000 DEG C.
Preferably, in the biomass gasifying furnace of the cleavable tar, the multiple air inlet pipe is along the burning
The axial direction of room is scattered in multilayer, and every layer of air inlet pipe includes several air inlet pipe, adjacent two layers air inlet pipe 2~3cm of interval.The implementation
Example is more conducive to form the uniform air film of combustion-supporting gas near wall in the combustion chamber, the uniformity of air film is improved, to make
Burning near Inner Wall of Combustion Chamber also more evenly, and then makes the more uniform temperature near Inner Wall of Combustion Chamber, and second pyrolysis is indoor
Heating temperature is also more evenly.
Preferably, in the biomass gasifying furnace of the cleavable tar, the aperture of the stomata is 0.2~0.5cm.
When aperture in the range, can to second pyrolysis room spray multiply air-flow, play the role of disturbing fuel gas containing tar.When
When the flow velocity or excessive flow of high temperature air, then it may will affect the lysis efficiency of tar.
The tar removal efficiency of present invention fuel gas containing tar can achieve 99.99%.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
