Background technique
For most of different types of applications (such as round fluidized bed combustion (CFB burning), calcining, oil are recycled) and
For other processing, it is necessary to feed gas into next and/or last cleansing phase (such as electric precipitator
(ESP)) it removes from hot flue gases or product gas mixture containing solid before and/or separates solid, to meet environment
Or especially product specification.
In general, using gas cyclone separator is mixed from hot flue gases or product gas in the application field of these processing
Close the solid that particle form is filtered out in object.This cyclone separator is also used to steam power plant, in steam generator and whirlpool
From separation water in live steam or for the condensate separation in gas cooler between turbine.
Many functions and performance-relevant important ginseng with this cyclone separator have been had studied in enough degree
Number.These parameters include pressure, temperature, speed and the particulate load of gas and the geometry of cyclone separator.Here, special
Not, the corresponding cover board of cyclone separator or lid, the dip-tube of also referred to as vortex finder and discharge port and solid particle
Discharge is related.
Compared with other technologies for separating solid and gas, one of cyclone separator is the disadvantage is that this isolated effect
Rate is relatively low, especially in the case where fines of the size less than 10 μm.Efficiency about this sized particles is most
It is limited to 90 to 95% or even lower.
Since at the end of the 19th century, many investigation have had been carried out to determine single operation parameter and/or geometric parameter
Influence to the separative efficiency of gas cyclone.
This separative efficiency is influenced by series of parameters (such as particulate load and particle size).In addition, cyclonic separation
Gas velocity in device and its sub-component has decisive influence to the performance of cyclone separator.In the sub-component of cyclone separator
Pure gas speed directly influenced by the geometry of these components of cyclone separator.In addition, cyclone separator is interior
Parts (such as form of dip-tube (vortex finder), top (taper lower prong), inlet duct), ventilation etc. directly affect
Dust entrainment and separative efficiency.
In addition, in order to meet different industrial requirements, about the orientation (reversed and one-way flow) of entrance, there are different rotations
Wind separator designs (vertically or horizontally).Design for high yield is characterized in that shorter main body and furthermore allows big
The larger open of handling capacity.The pressure loss under this design conditions is usually relatively low, and wherein deposition rate is relatively low.With this
On the contrary, the design for higher efficiency is characterized in that long main body and small opening.On the one hand, this design leads to deposition speed
Rate is high, also leads to pressure loss height but then.
According to the high performance counter current cyclone separator including cylindrical vortex detector a kind of known to 0 972 572 A2 of EP.
The document discloses the sizes and geometry of the extra high discrete component of efficiency for leading to cyclone separator of cyclone separator
Between relationship.
According to a kind of combustion apparatus known to 10 2,013 207724 A1 of document DE, wherein main burning is in cyclone separator shape
It is carried out in chamber.The dip-tube or vortex finder of this cyclone separator shape chamber have the form of venturi flume.
According to one kind dip-tube or vortex finder made of metal grate known to 0 447 802 A2 of document EP.Institute
It states dip-tube or vortex finder includes several honeycomb-like parts.
In general, the efficiency of well-designed cyclone separator can be improved by increasing tangential velocity, but this also causes
The pressure loss on cyclone separator increases.However, this higher pressure loss on cyclone separator is inevitably led
Cause the pressure loss in whole system higher, therefore the increase in demand to electric energy.Further, since the inner side and outer side of dip-tube it
Between subsequent high pressure gradients, the higher pressure loss also leads to the stronger stress of dip-tube.
Therefore, a purpose of the utility model is to provide one kind and cyclone separator can be made to have high separating efficiency and had
The novel dip-tube for thering is middle pressure to lose.The high loss of this dip-tube inlet by avoiding minor diameter and, is achieved.
However, realizing high tangential velocity by guiding the minor diameter in nozzle into.Due to this small cross section exist only in it is relatively short
Region on and guidance to it realized with the lesser pressure loss, therefore loss of total pressure reduces, while tangential velocity is several
It is identical.By adjusting flowing and subsequent diffuser on the same direction, a part of pressure loss is in addition also restored.
Utility model content
Above-mentioned purpose is addressed by the dip-tube and/or cyclone separator of the utility model.

Minimum cross-section become smaller in a converging fashion.Since the neck part of dip-tube, dip-tube is swollen again along airflow direction
It is swollen to the bigger cross section limited by diffuser inside diameter.
When particle is dispersed phase, in order to separate particle from gas, the gas vent of cyclone separator must be about it
Diameter progress is appropriately designed, to avoid the high pressure loss while maintaining the major function of swirl stabilization and separative efficiency.
(wherein gas phase is dispersed phase to the hydrocyclone of separation gas and relative volumetric flow is small from the fluid with higher density
Much) it is not the case.Therefore, vortex finder can correspondingly be designed as having much smaller vortex finder diameter,
Or from rapidly (such as the index of the nozzle entrance shape (loudspeaker or Laval shape shape) relative to axis with very wide-angle
Ground, non-linearly) the vortex finder diameter that reduces.Due to very small volumetric flow of gas, this design still can
Middle pressure is caused to lose, because gas is dispersed phase.On the other hand, hydrocyclone is needed in eddy current probe inlet sometimes
Additional device (such as crash panel) enters vortex finder to avoid denser fluid.The whirlwind of particle is separated from gas
Separator does not need this device.In fact, such device is unfavorable, because particle may interact with them, this
It will lead to higher breakage of particles (such as due to particles hit).In addition, the non-linear reduction of vortex finder diameter will increase
The pressure loss of the cyclone separator of solid is separated from gas, because volumetric flow of gas is much larger than particle volume flow.
