High pressure gas can form spiral current moving curve, moreover, by height from inlet cylinder is tangentially entered in inlet cylinder
It calms the anger the speed of body itself, the helical flow curve of high pressure gas is to rotate from top to bottom, forms the state of similar cyclone, In
The central axis of inlet cylinder forms low-pressure area, and the low-pressure gas entered to lower part forms the drive revolved upwards, and sweeps along low
Body of calming the anger forms second spiral force.
Barrel dliameter gradually expands the inlet cylinder from bottom to top, after high pressure gas enters inlet cylinder, with inlet cylinder barrel dliameter
Variation promotes gas spiral shape to rotate, moreover, barrel dliameter variation promotes the speed of gas to increase when high pressure gas moves from top to bottom
Add, and then the low-pressure gas for driving bottom to enter is mixed, and it is driven to move upwards.
It, can be in pressurized gas inlet 4 in order to reach this effect herein it is also mentioned that high pressure gas tangentially enters inlet cylinder
The improvement of a little structures is done at place, in some embodiments, it is proposed that inlet cylinder is designed as volute structure, the air inlet of spiral case 11 in the position
Mouth is pressurized gas inlet 4, and the shell of spiral case 11 surrounds the top barrel of inlet cylinder.I.e. inlet cylinder is in pressurized gas inlet 4
Inlet cylinder side wall rotates outward the volute inlet (entrance i.e. high-pressure inlet guiding worm pipe 12) that formula extends to form.
The barrel dliameter of mixing drum is less than the aperture of mixed gas through-hole 9, promotes high pressure gas and low-pressure gas from mixed gas
9 variable diameter of through-hole is into mixing drum, and the friction and collision of gas can rapidly increase in variable diameter, generates the local pressure loss, is formed
It is vortexed turbulent fluctuation.High pressure gas and low-pressure gas are discharged after mixing in mixing drum sufficiently from mixed gas outlet.It is mixed in Fig. 1
The sub- mixed gas outlet of gas outlet duct draws mixed gas.The mixed gas outlet conduit can use bend pipe 8.
Gas cyclone mixer further include: low-pressure gas guide pipe, low-pressure gas guide pipe are protruded into from low-pressure gas entrance
To inlet cylinder.In order to which low-pressure gas to be introduced into inlet cylinder as far as possible, it is transported to predeterminated position, high pressure gas is facilitated to adsorb
It takes up and moves upwards, the upper end of low-pressure gas conduit is extend into inside inlet cylinder.The low-pressure gas conduit extend into inlet cylinder
Part is straight tube, and along the central axial of inlet cylinder.
The structure type of two kinds of inlet cylinders is given below:
Form one, inlet cylinder include: back taper cylinder 2, spiral case 11；The top edge of back taper cylinder 2 and the shell of revolution of spiral case 11
Body bottom edge is spliced to be connected, and forms closed cylinder.The shell of spiral case 11 coils in the horizontal plane, i.e. the circular shell structure of spiral case 11
At the top barrel of inlet cylinder.In order to avoid gas leakage, the top edge of back taper cylinder 2 and the housing lower margin closing of spiral case 11
Formula splicing, seam crossing sealing.
Form two, inlet cylinder includes: back taper cylinder 2, straight tube 3 and spiral case 11, by straight between back taper cylinder 2 and spiral case 11
Cylinder 3 carries out spliced connection, to form closed cylinder.That is the closed spelling of the lower edge of the top edge of back taper cylinder 2 and straight tube 3
It connects, the closed splicing of lower edge of the top edge and spiral case 11 of straight tube 3.The overall length of back taper cylinder 2 and straight tube 3 should not exceed inherently
Eddy flow length, wherein intrinsic eddy flow length be vortex minimum point to mixed gas outlet (bend pipe 8) bottom end linear distance.
Welding or flanged joint can be used in closed splicing (i.e. spliced connection) in form one and form two, in the two
Junction splicing seams are closed using gasket.
In form two, back taper cylinder 2 and straight tube 3 can be made of one formula structure, or straight tube 3 and spiral case 11 are done
Integrated structure.
In form one, the tangent line of pressurized gas inlet 4 extends up to high pressure gas with the top edge of back taper cylinder 2
The tangent line of body entrance 4.In form two, pressurized gas inlet 4 along straight tube 3 upwardly extend after tangential direction at this.No matter
How to limit, the circumference of 2 top edge of back taper cylinder is identical as the central axis of the cross-sectional circumferential of straight tube 3.
Based in above-mentioned various schemes, mixing drum includes: pre-mix zone and mixed zone, and pre-mix zone is under mixing drum
Portion is connected with mixed gas through-hole 9；Mixed zone is in the top of mixing drum, is connected with mixed gas outlet.Mixed gas
Through-hole 9 is connected to pre-mix zone, and mixed gas through-hole 9 is premix in the space that the lower part of mixing drum is formed in close pre-mix zone
Room 6 is closed, and the diameter of mixing drum lower part is less than the diameter of mixed gas through-hole 9.And the pre-mix zone of mixing drum lower part is another
The space that one end and mixed gas outlet (bend pipe 8) are formed is mixing chamber 7.
Premix is located in the both ends outlet of several helix tubes 10 that are internally provided with of premixing cavity 6, helix tube 10
6 two sides of room are closed, the outlet direction of helix tube 10 is consistent.I.e. the lower end of helix tube 10 is connected with mixed gas through-hole 9, on
End is connected with mixed zone.
In some embodiments, the diameter of all helix tubes 10 differs.It is set in pre-mix zone in pre-mix zone
The flow velocity of gas is different in the helix tube 10 of different tube diameters, and gas is after the helix tube 10 of different tube diameters can be such that air-flow reaches
Time of mixing chamber 7 is different, promotes fluid along the blending of pipeline axial direction, so that gas is can along 6 direction of premixing cavity
It is uniformly mixed, mixed gas is discharged through mixed gas outlet bend pipe 8.
In conjunction with the working principle of the gas cyclone mixer of the invention of Fig. 1,2,3,4 are as follows:
High pressure gas tangentially enters mixer along spiral case 11 by pressurized gas inlet 4 with certain speed, is mixing
Make high-speed screw movement from top to bottom in the straight tube 3 and back taper cylinder 2 of device.And rotation low pressure is produced in the central axis of mixer
Area.Wherein low-pressure gas enters mixer through low pressure inlet guide pipe 5 by low-pressure gas import 1, wherein since high pressure gas exists
The center low pressure that mixer high speed spiral generates, which is acted on, is absorbed into mixer for low-pressure gas, wherein the height for movement of spinning
Body of calming the anger drives low-pressure gas in 2 contract of back taper cylinder to center flow, and the secondary interior bumpy flow for being upwardly formed rising enters
Mixed gas through-hole 9 is premixing cavity, and gas is by caliber change during premixing cavity 6 are entered in premixing cavity
When, the friction and collision of particle can rapidly increase, and generate the local pressure loss, form vortex turbulent fluctuation.In premixing cavity 6
The time of gas mixing chamber after the helix tube 10 of different tube diameters can be such that gas reaches is different, promotes gas along pipeline axial direction
Blending.Mixed gas is discharged through mixed gas outlet bend pipe 8.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
