Description
Technical field
Chemical Manufacture air and gas mixer is the utility model is related to, particularly a kind of coal gas for charring process mixes
Device.
Background technology
, it is necessary to carry out Quick uniform mixing to two or more different types of media in Chemical Manufacture.In charing work
Needed in skill to uniformly being mixed into the coal gas in carbide furnace and air, there are the following problems for existing blender：
(1) existing blender is welded with inclined swirl vane in inner tube and outer tube nozzle, makes air in reducing mouth
Effect is lower to be sprayed at a high speed, and the structure coal gas and air contact time are short, it is impossible to is sufficiently mixed, is caused to burn uneven.
(2) existing mixing tube outer tube one end is outer tube spout, and outer tube spout does not have reducing, causes air velocity not increase,
In furnace injection distance not enough, furnace flame skewness is caused, uneven heating is even.
(3) existing mixing tube air header mouthpiece and gas main mouthpiece in the same direction set, due to gas flow compared with
Greatly, without corresponding buffering, outer tube is directly incorporated into, coal gas is directly flushed in outer wall of inner tube, and wash away causes tube wall to rush for a long time
Brush is serious, it is necessary to regularly replace pipeline.And the airflow scouring pipeline of high speed, pipeline is in vibration, have to the stabilization of system
Certain influence.
Based on insufficient present on, there is provided a kind of coal gas and air are right in space division mixing, mixed process in cyclone pipe
The outer tube of blender has certain cushioning effect and reduces the air velocity of coal gas, reduces washing away to outer wall of inner tube
New blender turns into technical problem urgently to be resolved hurrily in current this retort technique productions.
Utility model content
To solve drawbacks described above present in prior art, the purpose of this utility model is to provide a kind of for retort
Air and gas mixer, the device blender can carry out Quick uniform mixing to two or more different types of media；Solve
Driven during two kinds of fluids mixing by the quick jet of main fluid and introduce flow of fluid and mix, produced in mixed flow moment point
Stream, multiple cross-mixing and reverse eddy flow reach rapid, are equably spread in whole fluid, reach moment and rapidly and efficiently mix
Purpose.
The utility model is realized by following technical proposals.
A kind of air and gas mixer for charring process, including the air being enclosed in coal gas cyclone pipe enter the double of boiler tube formation
Layer tubular construction, one end that boiler tube is entered in the air for stretching out coal gas cyclone pipe are connected with air intlet pipe, are being inserted in coal gas cyclone pipe
Air enter boiler tube one end be taper air burner, bimetallic tube stage casing be provided be connected on coal gas cyclone pipe be in 90 °
The gas pipe of distribution；Reducing conical pipe is provided with the outer end of the coal gas cyclone pipe at corresponding air burner end, is set on reducing conical pipe
There is outlet square tube.
Preferably, one end of the air intlet pipe is provided with quirk observation temperature valve.
Preferably, air burner has a certain distance apart from reducing conical pipe in coal gas cyclone pipe.
Preferably, the diameter of the gas pipe is more than the diameter of air intlet pipe.
Compared with prior art, it is the advantages of the present apparatus：
1) blender is conical nozzle in inner tube and outer tube orifice design, can drive coal gas, the shape in coal gas cyclone pipe
Into gas turbulence；And the air burner in coal gas cyclone pipe apart from reducing conical pipe there is a certain distance coal gas and air to exist
Eddy flow inner air tube is sufficiently mixed, and burning is evenly.
2) variable diameter design of outlet causes air velocity to accelerate, and burning in stove evenly, is heated evenly.
3) the bend pipe design of gas entry pipe makes air-flow wash away dynamics reduction to pipeline, and the square tube design of outlet reduces
The vibration of pipeline.
The present apparatus transmits energy, momentum and the device for making quality mutually blend using the viscous shear power between fluid.It
There is no mechanical moving element, simple in construction, reliable operation.Two kinds of different mediums are widely portable in production technology in pipeline
Technique mixing.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples, but is not intended as to this practicality
The new foundation for doing any restrictions.
As shown in figure 1, a kind of air and gas mixer for charring process, including outlet square tube 1, reducing conical pipe 2, coal gas
Cyclone pipe 3, air burner 4, air enter boiler tube 5, air intlet pipe 6, quirk observation temperature valve 7 and gas pipe 8, wherein air and entered
Boiler tube 5, which is enclosed in coal gas cyclone pipe 3, forms two-layer pipe, enters one end connection of boiler tube 5 in the air for stretching out coal gas cyclone pipe 3
There is air inlet tube 6, one end of air intlet pipe 6 is provided with quirk observation temperature valve 7；Enter in the air for being inserted in coal gas cyclone pipe 3
One end of boiler tube 5 is provided with the air burner 4 of taper, is provided with bimetallic tube stage casing and is connected to being distributed in 90 ° on coal gas cyclone pipe 3
Gas pipe 8；Reducing conical pipe 2 is provided with the outer end of the coal gas cyclone pipe 3 at the corresponding end of air burner 4, is set on reducing conical pipe 2
There is outlet square tube 1.
As shown in Figure 2,3, gas pipe 8 is in the bend pipes of 90 ° of distributions, the hypomere of gas pipe 8 and sky in bimetallic tube entrance point
6 liang of pipe parallel arrangements of gas inlet tube, the diameter of gas pipe 8 are more than the diameter of air intlet pipe 6.
As shown in figure 4, gas pipe 8 can be distributed in the either end of bimetallic tube both sides.
This facilities air enters boiler tube 5 by the air inlet of air intlet pipe 6, in the presence of the end reducing mouth of air burner 4
Spraying at a high speed, coal gas and air contact time are short, and caliber diminishes suddenly, air velocity increase, while in air burning mouth front end
Provided with coal gas cyclone pipe, air velocity increases suddenly, drives coal gas, gas turbulence, coal gas and sky are formed in coal gas cyclone pipe
Gas space division in coal gas cyclone pipe 3 mixes.Because air burner 4 and reducing conical pipe 2 are provided with a segment distance in stove so that empty
Jet-impingement lengthening distance, is heated evenly；When gaseous mixture is by reducing conical pipe 2, because caliber diminishes suddenly, gaseous mixture speed
Increase, distance is farther in penetrating stove, and furnace flame distribution is wider, is heated evenly.Meanwhile the exporter set before reducing conical opening
Pipe, which makes, to be more convenient, and is easily adjusted the error of centralization, and has certain cushioning effect.
Consider that being directly incorporated into outer tube without the coal gas buffered accordingly can cause coal gas direct because gas flow is larger
Outer wall of inner tube is flushed in, wash away causes tube wall to wash away seriously, it is necessary to regularly replace pipeline for a long time.And the airflow scouring pipe of high speed
Road, pipeline is in vibration, the stabilization of system is had a certain impact.This facilities air inlet tube with gas inlet pipe phase
Connect end and be designed as being in 90 ° of distributed architectures, coal gas passes through one 90 ° of bend pipe before outer tube is entered, and makes the air velocity of coal gas
Reduce, reduce and outer wall of inner tube is washed away, while the square tube exported reduces the vibration of tube wall.
The utility model is not limited to above-described embodiment, on the basis of technical scheme disclosed in the utility model, this
The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour can is special to some of which technology
Sign makes some and replaces and deform, and these are replaced and deformed in the new protection domain of this reality.
