Description

The spinning oil fume purifying apparatus
Technical field
The invention belongs to the synthetic fibers technical field, be specifically related to a kind of safe and efficient, steady in a long-term spinning oil smoke waste gas purifying processing device that moves.
Background technology
In the production process of synthetic fibers (precursor), especially when drawing-off, be cohesive force, minimizing static, the raising spinnability that increases tow,, usually need be oil solution dedicated in the spinning of strand surface attachment.The high temperature and high speed of draw roll can make the volatilizable component of the part of spinning oil be heated and evaporate into vaporific oil smoke, and the aspirator through being arranged on the draw roll top drains into outdoor.If the oil flue waste gas disperse in periphery, produces penetrating odor, can cause serious oil flue waste gas to pollute to surrounding environment.The thing that agglutinates in the flue is inflammable, is serious potential safety hazard.
For the spinning government of Oil Fume, domesticly mainly contain following approach at present:
1) lengthening air channel: indivedual enterprises make part mist of oil in the waste gas drip nature by the lengthening air channel and are attached in the air channel, and large quantity of exhaust gas enters in the atmosphere.The chimney exhaust gas disperse produces penetrating odor in periphery, causes serious oil flue waste gas to pollute to surrounding environment.On the other hand, the thing cleaning of agglutinating of the oil smoke in tall and big chimney and the big and long air channel is very difficult, and the oil smoke that the clears thing that agglutinates can cause secondary pollution, but if untimely cleaning, its combustibility then is great potential safety hazard.
2) filer element type spinning cooking fume filter: the spinning oil smoke waste gas enters under the effect of aspirator by glass fibre cotton and does in the cylindric filer element type cooking fume filter of filter course, after adsorption filtration, can remove part oil smoke droplet, treatment effeciency is about 45%, and the waste gas after the processing directly enters atmosphere.The filer element type filter is removed the low and easy obstruction of efficient, can not efficiently move by continous-stable; Filter core cleans difficulty, and a large amount of rinse water dischargings can cause secondary pollution.In addition, the glass fibre filter core need be changed once every half a year, not only costs an arm and a leg, and the filter core of changing also is difficult to degraded, thereby causes noxious waste pollution.
2) drawer type cooking fume filter: in this treatment process, the spinning oil smoke waste gas is through special S type baffle plate, under balanced inertial collision centrifugation, enter in the drawer type cooking fume filter behind the removal larger particles oil smoke droplet, the waste gas of filtration directly enters in the atmosphere.The shortcoming of this technology is that to remove efficient low, only about 36.6%; The too thin then poor filtration effect of filter cloth, the too thick then resistance of filter cloth is too big, and smoke freely can not influence product quality and production on-site environment; Filter cloth is often stifled, and the rinse water intractability is big, changes to burn and easily causes secondary pollution.
4) spray column water spray absorbs (wet type) oil smoke processor: shower water sprays from top to bottom, under the hydraulic pressure effect through nozzle atomization, the spinning oil smoke waste gas from bottom to top reverse and the atomizing after the shower water contact-impact, and then be adsorbed in the water droplet, the gas after the processing is expelled to atmosphere from spray column top.There is the low shortcoming of treatment effeciency equally in this technology, is about 33.7%, simultaneously, have also that the spray column atomizing effect is poor, water droplet and oil droplet collision back absorptivity is low, behind the shower water oil-containing bigger, the discharging of intractability cause defectives such as secondary pollution.
5) filtration, polar-plate-type electrostatic (electric dust) precipitator bi-level treatment: promptly be provided with two row washing spray equipments in the cooking fume filter, spray is removed dripping than big mist of oil in the waste gas, and shower water recycles, and unabsorbed small mist of oil drips by the polar-plate-type electrostatic (electric dust) precipitator and removes in the gas.But the shower water that has absorbed oil smoke easily condenses into piece, stops up water pipe.On the other hand, temperature is on the low side during oil flue waste gas process polar-plate-type electrostatic (electric dust) precipitator, and little oil droplet is adsorbed on curing difficult removal in back on the dust collecting pole plate, and then influences electric-field intensity, causes oil smoke removal efficient to reduce, and facility can't stable and high effective operation.
This shows that for the spinning oil smoke, domestic also do not have maturation treatment technology efficiently at present, scientificlly and effectively administer the spinning oil smoke waste gas and pollute that the development of industry is had crucial effects.Though having preferably in the other industry exhaust emission is administered, uses by shell and tube electric fishing storage, such as tar dedusting (CN200620078845.3).But compare with the spinning oil smoke waste gas, the temperature of tar waste gas is higher, thereby is difficult for agglutinating on electrode, does not have the obstruction of easily agglutinating, the thing that agglutinates is inflammable and removes problem such as difficulty.And the source of spinning oil smoke waste gas disperses relatively, pools together when the spinning oil smoke aspirates through the inlet scoop that is arranged on different spinning stations top, and when arriving at trap by long air channel, its temperature range of decrease is very big, is very easy to occur the phenomenon that agglutinates.Therefore, simply apply mechanically existing electric fishing storage, can not solve the processing difficult problem of spinning oil smoke fully.
