Abstract
The invention relates to the technical field of combustors, in particular to a biomass gas combustion device. The biomass gas combustion device comprises an outer pipe. A biomass gas inlet and an air inlet are formed in the outer pipe from left to right. The right end of the outer pipe is communicated with a combustion cavity. The left end of the outer pipe is rotationally matched with a rotating shaft. The rotating shaft is in key joint with a flow distribution cylinder. The flow distribution cylinder is sequentially divided into a cone and a cylinder from left to right. The cone is opposite to the biomass gas inlet. Multiple biomass gas inlet holes are formed in the peripheral wall of the cone. The cylinder is opposite to the air inlet. Multiple air inlet holes are formed in the peripheral wall of the cylinder. Compared with traditional natural mixing, the gas mixing speed is higher, and gas is more evenly mixed.
Description
Technical field
The invention belongs to technical field of burner.
Background technology
Biomass energy, as the fourth-largest energy in the world, accounts for about 14% of global energy total flow.Biomass energy wide material sources, volatile matter content is high, and content of ashes is low, and sulfur content is low, because growing environment absorbs CO
2amount is equivalent to the CO of burning and exhausting
2amount, therefore realizes CO in energy conversion process
2clean discharge capacity is similar to zero, is conducive to improving greenhouse effects.The technology of research and development efficiency utilization biomass energy, saves conventional fossil energy, Optimization of Energy Structure, has very important significance.Biogas is the imflammable gas produced through gasification furnace with agricultural crop straw and forestry waste, and be the approach of biomass energy to heavy industrialization application development, current biogas burner is just progressively promoted utilization.
Biogas as during fuel need fully mix with air in the burner, existing burner comprises inner and outer tubes, interior pipe is positioned at outer tube, biogas is passed in interior pipe, air is passed between outer tube and interior pipe, mix in air and the combustion gas cavity that pipe communicates within the outer tube, then jet out flames after being lighted by igniter.The shortcoming of this burner is: for naturally mixing between air and combustion gas, and the speed of mixing is slow, mixes uneven, easily occurs the situations such as tempering.
Summary of the invention
The invention is intended to provide the biogas burner that a kind of mixing velocity is fast, mix.
Biogas burner in this programme, comprises outer tube, and this outer tube has biogas import and air intlet from left to right, and the right-hand member of outer tube communicates with combustion chamber, and the left end of outer tube is by the rotating shaft that has been rotatably assorted, and this rotating shaft is connected with a shunt cylinder key; This shunt cylinder is divided into cone and cylinder from left to right successively, and wherein cone is relative with biogas import, and this cone perisporium is provided with some biogas air admission holes; Above-mentioned cylinder is relative with air intlet, and cylindrical peripheral wall is provided with some air inflow openings.
Beneficial effect: the present invention arranges rotating shaft at outer tube left end, and shunt cylinder is fixedly connected with rotating shaft, when making axis of rotation like this, drives shunt cylinder to rotate.And air and biogas are blasted in outer tube by air blast, such gas (air and biogas) is while high-speed straight-line motion, shunt cylinder rotates and makes the gas between shunt cylinder and outer tube form eddy flow, biogas enters in shunt cylinder from the biogas air admission hole of cone, air then enters in point circulation from air inflow openings tangent line and forms swirling eddy, divide air and the mixing of biogas fast rotational in circulation, compare traditional naturally mixing, the gas and vapor permeation speed of this programme is faster, mixes more even.
Further, described air inflow openings is that rectangular strip is poroid, and the long limit of this air inflow openings is parallel with cylinder axis, during axis of rotation, air between outward appearance and cylinder forms eddy flow, and enters cylinder interior from air access holes tangent line, then mixes with the biogas in cylinder.
Further, described rotating shaft is coordinated with the installing hole on outer tube by ball bearing, under ball bearing friction, rotates more flexible.
Further, perisporium and the outer tube of cylinder fit tightly, and form the annular compartment isolated with biogas import, prevent biogas and air from mixing in annular chamber between the perisporium of cylinder and outer tube.
Further, the quantity of air inflow openings is 12, and intake velocity is fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention biogas burner.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: outer tube 1, biogas import 2, air intlet 3, shunt cylinder 4, cone 41, cylinder 42, biogas air admission hole 5, rotating shaft 6, ball bearing 7, mixed gas outlet 8, air access holes 9.
Embodiment biogas burner is substantially as shown in Figure 1: comprise and be positioned at outer tube 1, this outer tube 1 has biogas import 2 and air intlet 3, the left end of this outer tube 1 has installing hole, the right-hand member of outer tube 1 communicates with the combustion chamber at flame projector place.This shunt cylinder 4 comprises the shaping cone of integrally casting 41 and cylinder 42, this cone 41 left end is connected with rotating shaft 6 key, this rotating shaft 6 is coordinated by ball bearing 7 with the installing hole of outer tube 1, the perisporium of this cone 41 has some biogas air admission holes 5 communicated with biogas import 2.The mixed gas outlet 8 communicated with combustion chamber is had at cylinder 42 right-hand member of shunt cylinder 4, annular compartment is formed between the outer wall of this cylinder 42 and outer tube 1, the outer wall of cylinder 42 closely cooperates (namely this annular compartment does not communicate with biogas import 2) with the lower port wall of air intlet 3, cylinder 42 perisporium has with cylinder 42 axis parallel and the poroid air access holes 9 of orthogonal bar, the long limit of air inflow openings 9 and the axis being parallel of cylinder 42, this air access holes 9 number is 12, these 12 air access holes 9 be evenly distributed on cylinder 42 perisporium on.
The course of work of above-described embodiment is: biogas is blown in outer tube 1 from biogas import 2, and by the biogas air admission hole 5 on cone 41 wall of conically shaped, enters shunt cylinder 4 inner; Now, air is blown into annular compartment by air blast through air intlet 3, and rotating shaft 6 is simultaneously rotated, and whole shunt cylinder 4 is rotated, and the air in annular compartment then eddy flow occurs, and air enters in shunt cylinder 4 through air access holes 9 tangent line.The air that such tangent line enters shunt cylinder 4 inside then mixes with biogas rapidly, forms eddy flow, mixes more even.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
