Abstract
The utility model relates to a kind of biological fuel gas elbow with dedusting function, comprise elbow body, the bend loss of described elbow body is circumscribed with bypass tube, the entrance of described bypass tube is in the upwind of bend loss, the outlet of described bypass tube, at the lower wind direction of bend loss, is provided with dust filter in described bypass tube.Bypass tube of the present utility model is connected on bend loss outward, effect due to centrifugal force, a large amount of dust are separated and enter the dust filter in bypass tube with a small amount of gas from dust-containing airflow, thereby dust residual in combustion gas is filtered to collection, improved the quality of biological fuel gas, only need one section of elbow just can play simply and easily good dust removing effects, the dust of filtering combustion gas more thoroughly while containing a plurality of this elbow in conveyance conduit, has reduced the input cost of large-scale dusting apparatus.The utility model can be applicable to the conveying of biological fuel gas.
Description
Technical field
The utility model relates to biological fuel gas transportation art, particularly relates to a kind of biological fuel gas elbow with dedusting function.
Background technique
Biological fuel gas is different from rock gas, and rock gas is cleaner, and Dust Capacity in biological fuel gas is very large, so biological fuel gas must be removed as far as possible dust before coming into operation.
Biological fuel gas adopts the methods such as current, water spray to carry out dedusting conventionally at present, also the employing condensation method dedusting having, the patent " condensation-type purifying apparatus for biomass combustible gas " that concrete visible publication number is 201999905U. but be to adopt which kind of mode all to need to adopt special-purpose dust removal apparatus, these install not only complex structure, have taken a large amount of spaces, but also early investment that will be huge and the operation maintenance in later stage have increased cost beyond doubt for user like this.
Model utility content
In order to overcome above-mentioned technical problem, it is a kind of simply and easily with the biological fuel gas elbow of dedusting function that the purpose of this utility model is to provide.
The technological scheme that the utility model adopts is:
A kind of biological fuel gas elbow with dedusting function, comprise elbow body, the bend loss of described elbow body is circumscribed with bypass tube, and the entrance of described bypass tube is in the upwind of bend loss, the outlet of described bypass tube, at the lower wind direction of bend loss, is provided with dust filter in described bypass tube.
Preferably, described bypass tube is curved along its length, and being designed with of arc helps gas and pass through smoothly.
Gas when elbow bulk flow always along its axial direction, in order to guarantee unobstructed when bypass tube flows of gas, also in order to reduce the suffered resistance of gas while flowing into bypass tube from elbow body, preferably, the plane at described bypass tube axis place and the plane almost parallel at elbow body axis place.
As the further improvement of technique scheme, described bypass tube is rectangular tube, adopts rectangular tube exceeding affect primary path air quantity in the situation that, guarantees that to greatest extent near the wind of primary path tube wall enters bypass tube.
As the further improvement of technique scheme, described dust filter is porous ceramic filter element, and not only filter capacity is strong for this filter core, absorption efficiency is high, and can make water clean, thereby recycles, cost-saving.
Further improvement as technique scheme, is provided with reducing pipe in described bypass tube, and the larger pipe end of described reducing pipe opening is towards the air intake direction of bypass tube.When gas flow is crossed reducing pipe, because bore diminishes gradually, airspeed increases gradually, avoids gas backstreaming.
As the further improvement of technique scheme, before entering dust filter, need to promote wind speed, described reducing pipe is positioned at the upwind of dust filter.
As the further improvement of technique scheme, described bypass tube comprises that two sections are fixed on fixed tube on bend loss and are dismantled and assembledly connected to two sections of adjustable pipe between fixed tube, and described dust filter is arranged in adjustable pipe.Adjustable pipe is taken out and can be changed or safeguard dust filter, improve the convenience of work.
As the further improvement of technique scheme, between described adjustable pipe and fixed tube, by flange, be connected.
The beneficial effects of the utility model are: bypass tube of the present utility model is connected on bend loss outward, effect due to centrifugal force, a large amount of dust are separated and enter the dust filter in bypass tube with a small amount of gas from dust-containing airflow, thereby dust residual in combustion gas is filtered to collection, improved the quality of biological fuel gas, only need one section of elbow just can play simply and easily good dust removing effects, the dust of filtering combustion gas more thoroughly while containing a plurality of this elbow in conveyance conduit, has reduced the input cost of large-scale dusting apparatus.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
The biological fuel gas elbow with dedusting function as shown in Figure 1, comprises elbow body 1, and the bend loss of elbow body 1 is circumscribed with bypass tube 2, and the entrance of bypass tube 2 is in the upwind of bend loss, and the outlet of bypass tube 2 is at the lower wind direction of bend loss.
Bypass tube 2 is rectangular tube, curved along its length.In order to guarantee unobstructed when bypass tube 2 flows of gas, also in order to reduce the suffered resistance of gas while flowing into bypass tube 2 from elbow body 1, the plane almost parallel at the plane at bypass tube 2 axis places and elbow body 1 axis place, and in the present embodiment, the plane at two days axis places overlaps substantially.
In the present embodiment, in bypass tube 2, be provided with dust filter, the porous ceramic filter element 3 of this dust filter for making with silicious marl, not only filter capacity is strong for this filter core, absorption efficiency is high, and can make water clean, thereby recycles, cost-saving.
In bypass tube 2, be also provided with reducing pipe 4, this reducing pipe 4 is positioned at the upwind of porous ceramics spool, and the larger pipe end of reducing pipe 4 openings is towards the air intake direction of bypass tube 2.When gas flow is crossed reducing pipe 4, because bore diminishes gradually, airspeed increases gradually, avoids gas backstreaming.
In the present embodiment, bypass tube 2 comprises that two sections are fixed on fixed tube 22 on bend loss and are connected to two sections of adjustable pipe 21 between fixed tube 22 by flange 23 is dismantled and assembled, and porous ceramics spool and reducing pipe 4 are installed in adjustable pipe 21.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
