Description
Technical field
This application involves cyclone separator technology fields, more particularly to a kind of cyclone system surely imitated and method.
Background technique
Cyclone separator is a kind of commonly used equipment for gas-solid, gas-liquid system and gas-liquid-solid system heterogeneous separation,
Working principle is tangentially to enter rotary motion caused by separator using air-flow, makes solid particle (or the liquid by larger centrifugal force
Drop) it gets rid of to separator wall surface, to separate with air-flow, then the dust-exhausting port of cone lower part is dropped down onto along separator wall surface downlink, leave
Separator；The cleaner gas rotating uplink in center, finally from the center exhaust pipe discharge at the top of separator.Cyclone separator knot
Structure is simple, cheap, efficiency is higher, pressure drop is moderate, can make of multiple material, and it is dense to can be used for high temperature, high pressure, high particle
The harsh operating conditions such as degree, high abrasion, high corrosion, maintenance that is easy to operate, needing is few, is widely used in process industrial, environment is protected
The fields such as shield.But there is also some shortcomings for cyclone separator, for example, separation effect poor to the adaptability of operation tolerance great fluctuation process
Rate is changed greatly with operation tolerance, and especially in reduction process tolerance, efficiency decline is significant.Because of the processing gas of cyclone separator
Measure ascending, efficiency increased with tolerance before this, when reaching a certain tolerance (referred to as maximal efficiency tolerance, Qmaxe) when efficiency reach
Maximum, then tolerance is further added by, and efficiency but declines；And then the increase of qi-regulating amount increases always everywhere for the pressure drop of cyclone separator.
The variation relation of the efficiency of cyclone separator and pressure drop qi-regulating amount everywhere is as shown in Figure 1.This is to say, cyclone separator only exists
It handles operation in the case that tolerance is slightly below its maximal efficiency tolerance and is only most reasonably.Tolerance is too low (to be lower than maximal efficiency
Handle tolerance) when, although the pressure drop of cyclone separator is lower, efficiency is also low, and it is more that particle runs damage；If handling tolerance is greater than maximum
Efficiency handles tolerance, not only low efficiency but also pressure drop is also high.Therefore, cyclone separator should all avoid being greater than it in processing tolerance
It is operated in the case where maximal efficiency processing tolerance.
Cause cyclone separator processing tolerance to fluctuate widely for operation fluctuation etc. in actual production process, leads to whirlwind
The separative efficiency of separator is unstable, efficiency reduces, particle runs the problems such as damage increases, and those skilled in the art has been presented for one
A little solutions.Such as, patent 1 (application number 201721819403.4) discloses " a kind of self-interacting type cyclone separator ", works as peace
When monitoring that exhaust ports dust concentration is higher mounted in the dust sensor of cyclone separator exhaust ports, then by the concentration of monitoring
Information is converted into the signal of stepper motor rotation by converter, is controlled using stepper motor and is mounted on cyclone separator air inlet
Adjustable plate rotation at mouthful achievees the purpose that control intake, to solve to enter the wind so that the venthole of blast pipe expands or reduces
When wind pressure at pipe is excessive, the problem of being mingled with more impurity in the air that is discharged at discharge pipe, and without human intervention, it uses
It is more convenient.For another example, patent 2 (application number 201611077274.6) disclose it is a kind of " filter effect can adjust automatically whirlwind
Separator and method " installs photoelectric sensor in the exhaust outlet of cyclone separator, is arranged using photoelectric sensor monitoring exhaust outlet
The light transmittance (namely granule density) of gas out, and signal is passed into automatic control unit processing, driving adjusts cam driven
Flow adjusts the rotation of coral plate to adjust the dusty gas flow velocity of air inlet pipe, to keep import gas velocity to stablize；Also pass through drive simultaneously
Dynamic adjustment gear adjusts insertion depth of the center inner cylinder in separator, (is separated with reaching to cyclone separator filter effect
Efficiency) real-time automatic control.But existing these schemes are all not ideal enough, all there are some defects: first is that being only applicable to
The situation that cyclone separator admission pressure is excessive, air quantity is excessive not can solve air inflow too low (lower than design tolerance) and cause
The problem of efficiency separator declines；Second is that monitoring system is complicated, measurement accuracy, the accuracy of dust sensor and photoelectric sensor
It is not high, and price is more expensive；Third is that control intake when wind pressure is excessive at blast pipe using air inlet adjustable plate, or with stream
Amount adjusts coral plate to control induction air flow ratio, and what is utilized is all Throttle Principle, will all generate restriction loss, and additionally increase energy consumption；And
And need cyclone separator handle technique tolerance be all often to be determined according to manufacturing technique requirent, be cannot arbitrarily change or
Limitation, the resistance to outflow for increasing air-flow is also possible to have an impact production process；4th, for the cyclonic separation of high-temperature gas
Device, dust sensor or photoelectric sensor are applied in high-temperature dusty gas environment and still have some problems, it is difficult to guarantee long week
Phase uses.Therefore, these scheme practicabilities of the prior art are poor, need to carry out further technological innovation.
