Abstract
The utility model discloses an efficient combustion device used for burning pyrolysis gas of a biomass carbonization furnace. The efficient burning device includes an air inlet end plate and a combustion chamber which are connected, wherein an air inlet is arranged in the air inlet end plate; a pyrolysis gas ingress pipe is arranged in the air inlet; a biomass oil ingress pipe is sleeved with the pyrolysis gas ingress pipe; an atomization nozzle is arranged at one end of the biomass oil ingress pipe adjacent to the combustion chamber; a plurality of guide vanes are arranged in the pyrolysis gas ingress pipe; a primary air ingress pipe communicated with the air inlet is arranged in the air inlet end plate; a plurality of fuel feeding ingress pipes are arranged at the combustion chamber adjacent to the air inlet end plate; an ignitor is arranged on the combustion chamber; and a secondary air ingress pipe is further arranged on the combustion chamber. The combustion device not only can burn the purified uncondensable pyrolysis gas, but also can burn the biomass oil and the like generated during the low-temperature pyrolysis process and the pyrolysis gas purification process when the biomass raw material is burned, so that the efficient recover and utilization of the pyrolysis gas energy are realized.
Description
Technical field
The utility model relates to a kind of burner that is used for biomass burning retort pyrolysis gas.
Background technology
Biomass energy has low-sulfur, low nitrogen, burnt active and zero CO of high ash as a kind of new forms of energy
2The characteristics of clean discharging.At present, biomass energy utilization technology comprises biomass direct combustion power generation technology, biomass gasification technology, biomass marsh gas technology and biomass carbonated forming technique etc.Because charing that biomass pyrolytic charing technology is produced and shaped article thereof have the calorific value height, be prone to store, be prone to grinding, not perishable, be suitable for advantage such as long distances, more and more receive people's attention.The pyrolysis charring technology is to utilize retort that biomass material is carried out low temperature pyrogenation, obtains three kinds of products such as biomass carbon, bio-oil and pyrolysis gas.Burn after the pyrolysis gas that obtains can purify, the heat that burning produces is as the external heat source of retort.But the burner with general burns, and the bio-oil that produces in low temperature pyrogenation and the purification process can't together burn, and bio-oil can not be fully used, and has reduced energy utilization rate.
The utility model content
The utility model technical problem to be solved is: a kind of efficient burning device that is used for biomass burning retort pyrolysis gas is provided.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: burner, comprise the air inlet end plate and the combustion chamber that link together, and be provided with air inlet in the air inlet end plate; Be provided with pyrolysis gas ingress pipe in the air inlet; Be provided with the bio-oil ingress pipe in being provided with in the air inlet end plate, the bio-oil ingress pipe is provided with atomizer near an end of combustion chamber, also is provided with the primary air ingress pipe that is communicated with air inlet in the air inlet end plate; The combustion chamber is provided with some ingress pipes that refuel near air inlet end plate place, and the combustion chamber is provided with igniter.
Described bio-oil ingress pipe is set in the pyrolysis gas ingress pipe.
Be provided with some flow deflectors in the described pyrolysis gas ingress pipe.
Also be provided with the auxiliary air ingress pipe on the described combustion chamber.
The utility model has the advantages that: can not condensation heat vent one's spleen after this burner not only can burn and purify; The living beings wet goods that low temperature pyrogenation process and pyrolysis gas purification process produce be can also the biomass burning raw material carry out, the high efficiente callback and the utilization of pyrolysis gas energy realized.
Description of drawings
Fig. 1 is low-grade pyrolysis air burner structural representation.
Among the figure: 1. air inlet end plate, 2. combustion chamber, 3. pyrolysis gas ingress pipe, 31. flow deflectors, 4. bio-oil ingress pipe, 41. atomizers, 5. primary air ingress pipe, 6. refuel ingress pipe, 7. igniter, 8. auxiliary air ingress pipe.
The specific embodiment
Describe the particular content of the utility model in detail below in conjunction with accompanying drawing and specific embodiment.
As shown in Figure 1, burner comprises the air inlet end plate 1 and combustion chamber 2 that link together; Be provided with air inlet in the air inlet end plate 1, be provided with pyrolysis gas ingress pipe 3 in the air inlet, be arranged with bio-oil ingress pipe 4 in the pyrolysis gas ingress pipe 3; Bio-oil ingress pipe 4 is provided with atomizer 41 near an end of combustion chamber 2; Be provided with some flow deflectors 31 in the pyrolysis gas ingress pipe 3, also be provided with the primary air ingress pipe 5 that is communicated with air inlet in the air inlet end plate 1, combustion chamber 2 is provided with two ingress pipes 3 that refuel near air inlet end plate 1 place; Combustion chamber 2 is provided with igniter 7, also is provided with auxiliary air ingress pipe 8 on the combustion chamber 2.
During use; In pyrolysis gas ingress pipe 3, feed the biomass carbonated stove pyrolysis gas after purifying in the combustion chamber 2; Feed in the combustion chamber 2 after atomizer 41 atomizings of living beings oil pipe 4 ends purifying the atomizer bio-oil; Natural gas via is refueled in the pipe 3 feeding combustion chambers 2, and all gases mixes with the air that feeds from primary air ingress pipe 5 and then in combustion chamber 2, carries out ignition by igniter 7, can go into air through auxiliary air ingress pipe 8 benefits in the combustion process; Make sufficient combustion, the high-temperature flue gas after the burning is able to utilize as the external heat source of retort.
Can not condensation heat vent one's spleen after this burner not only can burn and purify, the living beings wet goods that can also the biomass burning raw material carries out low temperature pyrogenation process and the generation of pyrolysis gas purification process has been realized the high efficiente callback and the utilization of pyrolysis gas energy.
