Abstract
The utility model discloses an adjustable hydrocyclone which can adjust the flame of a burner, comprising a cyclonic current cavity, a spiral cyclonic current blade, a connecting rod adjusting axial displacement of the cyclonic current vane, a drive frame and a gear box; wherein, the cyclonic current vane and the cyclonic current cavity are arranged correspondingly with one end bigger and the other end smaller; the cyclonic current vane is connected with the cool end of the burner through the connecting rod; the drive frame and the gear box are arranged on the cool end of the burner. The utility model has the advantages of cancelling the internal air passage, momentarily adjusting cyclonic current strength for primary air passage according to operation condition of furnace calcination, increasing thickness for annular jet, delaying mixing rate for coal powder and secondary air, lowering temperature for peak value of the flame, effectively prolonging the service life of refractory bricks for burning zone, increasing the rigidity of flame, reaching ideal match degree for hot flow distribution and clinker burning, improving quality and yield for the clinker, cancelling cyclonic current and direct current adjusting valve for traditional burners, obviously saving energy consumption for primary fan and accurately displaying blocking rate of the cyclonic current vane upon the cyclonic current cavity from the instrument panel.
Description
Technical field
The utility model relates to a kind of adjustable cyclone of regulating the burner flame shape.Belong to the rotary kiln burner technical field.
Background technology
Tradition rotary kiln multicenter combustor is made up of eddy flow wind passage and direct current wind passage and coal dust passage at least, is provided with cyclone in the eddy flow wind passage, and eddy flow wind passage and direct current wind passage are equipped with the volume damper door respectively.By regulating eddy flow wind passage and direct current wind passage air quantity ratio,, thereby change flame profile in the operation with change burner outlet jet spin intensity.Its major defect is: too much port number makes the jet core velocity attenuation too fast, and jet thigh penetration depth is not enough, causes that flame insufficient rigidity, forming effect are poor, flame is regulated dumb; Multiply wind has increased unnecessary turbulent flow resistance to flow output is increased in exit phase mutual interference; Because of outlet gap is little, be difficult in machined and the use guarantee higher axiality requirement, cause flame distortion deflection; Too much port number has reduced the exogenous wind passage by air quantity, makes the burner jacket pipe can not get enough cooling off and overheating deforming, causes that watering material feeding stress increases, and damages too early; In the operation combination of eddy flow wind passage and direct current wind channel valve aperture have infinite many, therefore and burner outlet jet spin intensity do not have clear and definite corresponding relation, operating personnel are difficult to grasp.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, propose a kind ofly to change the obstruction area of swirl vane to the eddy flow chamber by changing the swirl vane axial location, reach and change wind spin intensity of burner, the adjustable cyclone that is used for rotary kiln burner of adjusting flame profile.Technical solution of the present utility model: connecting rod, gear frame and transmission case by eddy flow chamber, helical form swirl vane and the axial displacement of adjusting swirl vane are formed, wherein swirl vane is corresponding design with the eddy flow chamber, they all be one big and the other end is little, swirl vane is connected with the burner cold junction by connecting rod, and gear frame and transmission case are located at the cold junction of burner.The utility model advantage: 1. cancelled interior wind passage, arbitrarily adjusted by adopting adjustable cyclone to make a wind passage swirl strength calcine operating mode according to kiln; 2. obviously increase annular jet thickness (being the twice of triple channel burner), delayed coal dust and secondary wind mixing rate, reduced the flame peak temperature, prolonged the clinkering zone refractory brick life effectively; 3. because annular jet thickness obviously increases, and flame " rigidity " increases, and makes the heat flux distribution of flame and clinker burning require to reach the ideal matching degree, the quality of grog and output will be significantly improved; 4. owing to invented adjustable cyclone, cancel conventional burners eddy flow wind and direct current wind control valve, can obviously save the primary air fan energy consumption; 5. design has cyclone position instrument board and burner outlet jet spin intensity that accurate corresponding relation is arranged on transmission case, and operating personnel are easy to grasp.
Accompanying drawing 1 is that the utility model is used in the example structure schematic diagram on the rotary kiln burner.
Accompanying drawing 2 is head structure for amplifying schematic diagrames of Fig. 1.
Accompanying drawing 3 is the transmission case structure for amplifying schematic diagrames among Fig. 1.
Among the figure 1 is the eddy flow chamber, the 2nd, and swirl vane, the 3rd, the mobile collar, the 4th, connecting rod, the 5th, transmission case, the 6th, adjusting handle, the 7th, the instrument board of indication cyclone position, the 8th, gear frame.
The contrast accompanying drawing, adjustable cyclone is installed in the port of export of burner.Transmission case 5 and gear frame 8 that adjustable cyclone contains eddy flow chamber 1, swirl vane 2, the mobile collar 3 and connecting rod 4 and is positioned at the burner cold junction.Swirl vane is corresponding design with the eddy flow chamber, they all be one big and the other end is little, swirl vane is fixed on the mobile collar, the mobile collar is connected by the tooth bars in connecting rod 4, gear frame 8 and the transmission case 5.Handwheel 6 on burner cold junction operation transmission case moves forward and backward swirl vane vertically in the eddy flow chamber.One time a wind part produces swirling eddy through behind the swirl vane, another part passes through from the gap bypass of swirl vane and the formation of eddy flow chamber wall, form axial flow, change the obstruction area of swirl vane by changing the swirl vane axial location to the eddy flow chamber, change a wind spin intensity to reach, regulate the purpose of flame profile.Swirl vane is accurately shown by instrument board 7 blocking rate in eddy flow chamber.
