The specific embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
As shown in the figure: Surface Engineering rust cleaning air cleaning core piece-rate system comprises core separator 1, cyclone collector 2, ash bucket 3, blower fan 4, separator inner core 5, clean air outlet 6, gas feed 7, recyclegas outlet 8 etc.
The present invention includes core separator 1; The side wall lower ends of said core separator 1 urceolus is provided with gas feed 7; Sidewall upper at said core separator 1 is provided with recyclegas outlet 8; Inner upper end at core separator 1 is provided with separator inner core 5, and the outer end of said separator inner core 5 is clean air outlet 6; Said gas feed 7 is connected with blower fan 4 through pipeline, supplies the power of flue gas recirculation; Recyclegas outlet 8 is connected with cyclone collector 2 through pipeline, and particle is collected by whirlwind; The exit, lower end of cyclone collector 2 is provided with ash bucket 3, and the gas vent of cyclone collector 2 upper ends is connected with the import of blower fan 4 through pipeline.
Blower fan can be replaced by a syringe, can use under hot conditions, and the present invention can have several kinds of variations, and adding is dense by dedusting, and the grit wear intensity is very big, can be connected on the core separator lower current area to blower fan.The research of the present invention through flow pattern and computer simulation experiment have been carried out the research of detailed strictness to the Secondary Flow in the cyclone dust collectors, and Secondary Flow is to cause to return to flow to make the main cause of cyclone dust collectors low performance.And the design of core separator has just in time overcome these limitation.
The flue gas of solids laden thing is through the import of blower fan (or syringe) introducing core separator, because the result of swirling motion, particle is shifted to periphery by the centre, and the gas of cleaning leaves through outlet, carries the particle peripheral flow.Be discharged to cyclone dust collectors, loop back core separator then.Power provides through air-introduced machine.Separation process and solids are collected in various parts and are independently accomplished; The core separator purifying gas flow; And the particle in the scavenge system, if the efficient of core separator is sufficiently high words, particle can not leave system; But circulation again and again all harvests them and removes it up to cyclone collector.In this system, two independently interactions between the parts make this system can obtain higher collection efficiency; Even the effect of gatherer is low; Because the efficient of core separator is high, overall system efficiency can be predicted out also very high, and overall system efficiency is ε; ε=(ε c * ε s)/(1-ε s (1-ε c)), wherein ε, ε s, ε c are respectively the efficient of system, core separator, cyclone collector.Check that this formula demonstrates, even gatherer efficient is low, as long as core separator efficient is high, overall system efficiency also is high.For example: if ε s is 99%, ε c is 30%, and the efficient of system is 96.7%.This phenomenon can make an explanation with another kind of method: for example: if be 99% to certain volume size particles ε s; This will mean at flue gas and leave before deduster is discharged to atmosphere; It will circulate 100 times; This explanation particle is through gatherer 100 times, and Here it is, and their can be by collected reason greatly.
