Abstract
The invention relates to an oil corrosion prevention method, in particular to an oil corrosion prevention method for the spinning oil dynamic circulation of a POY production line. Each oil storage tank 1 is corresponding to a spinning oiling area which comprises a plurality of spinning oil pumps 6, the spinning oil is stored in the oil storage tank 1, and continuously inputted to the plurality of spinning oil pumps 6 through an oil supplying pipeline 2 by the high-position oil liquid level of the oil storage tank 1 and the static pressure generated by the low-position spinning oil pumps 6; spinning oiling is realized by supplying oil to thread-lines through the spinning oil pumps, a local microcirculatory system is established corresponding to each oil storage tank 1, residual oil left after the spinning oil is sent to the spinning oil pumps 6 by the oil storage tanks 1 is pumped back the oil storage tanks 1 through a circulation pump 5 by an oil return pipe-line 3. The method solves the problem that the spinning oil is easy to go bad in static state, and makes up the defect that hard particles in the oil of the prior art block the oil pumps.
Description
Technical field
The present invention relates to a kind of anti-corrosive method of oil solution, particularly relate to a kind of anti-corrosive method of oil solution of spinning oil dynamic circulation of POY production line.
Background technology
In the polyester POY spinning process, carry out smoothly for guaranteeing spinning, must use a kind of spinning oil, this finish generally is placed near the storage tank of spinning machine, gets to oil nozzle by the spinning oil pump again and finishes spin finishing.Finish contacts with air, can produce bacterium when environment is fit to, and bacterium is that food is grown fast with the finish, forms dope or caking, finish corruption that Here it is.The corrupt effective ingredient that consumes finish on the one hand of finish also can be blocked micropore or tubule in the oiling device on the other hand, and putrefaction adheres to tow or goes up shortage of oil, all can cause product quality problem.Because it is finish is easy to generate bacterium and corruption gently then influences production efficiency and product quality, heavy then make and put in order the groove finish and scrap.Facts have proved that the finish in the static state is easy to generate corruption, and corrupt being difficult to of the finish in sealing or the dynamic motion taken place.
Existing anti-corrosion method is to add costliness preservative agent is arranged, and will clean the finish system in 1～3 month one time, and cost height, pollution are handled because of need stop greatly, also have influence on normally carrying out of production.
In addition, because can newly-increased hard particles in system's (raw material, storage tank, pipeline), when entering the spinning oil pump, also can stuck finish pump, cause the increase of device damage and maintenance cost.
Summary of the invention
The purpose of this invention is to provide a kind of anti-corrosive method of oil solution, a kind of anti-corrosive method of oil solution of spinning oil dynamic circulation of POY production line just is provided.The invention solves spinning oil easy corrupt problem when static state, remedied the deficiency of the stuck finish pump of hard particles meeting in the prior art finish.
A kind of anti-corrosive method of oil solution of the present invention, each finish storage tank 1 corresponding spin finishing district, a spin finishing district comprises some spinning oil pumps 6, spinning oil is stored in the finish storage tank 1, and the static pressure that produces by high-order finish liquid level and low level spinning oil pump 6 by finish storage tank 1 is incessantly carried spinning oil through oil supply line 2 to some spinning oil pumps 6, the spinning oil pump is realized spin finishing to the strand fuel feeding, corresponding each finish storage tank 1 is set up a local microcirculation system, and the unnecessary finish of finish storage tank 1 after spinning oil pump 6 is carried spinning oil returned in the finish storage tank 1 via circulating pump 5 by oil return pipeline 3.
As optimized technical scheme:
Aforesaid a kind of anti-corrosive method of oil solution, wherein, described circulating pump 5 is centrifugal circulating pumps.
The present invention also provides another kind of anti-corrosive method of oil solution, each finish storage tank 1 corresponding spin finishing district, a spin finishing district comprises some spinning oil pumps 6, spinning oil is stored in the finish storage tank 1, and the static pressure that produces by high-order finish liquid level and low level spinning oil pump 6 by finish storage tank 1 is incessantly carried spinning oil through oil supply line 2 to some spinning oil pumps 6, the spinning oil pump is realized spin finishing to the strand fuel feeding, corresponding each finish storage tank 1 is set up a local microcirculation system, finish in the finish storage tank 1 is carried spinning oil to spinning oil pump 6 after filtering through oil supply line 2 and through filter 4, and the unnecessary finish of finish storage tank 1 after spinning oil pump 6 is carried spinning oil returned in the finish storage tank 1 via circulating pump 5 by oil return pipeline 3.
Aforesaid a kind of anti-corrosive method of oil solution, wherein, described circulating pump 5 is centrifugal circulating pumps.
A kind of anti-corrosive method of oil solution of the present invention is a kind of dynamic circulation method, and static originally finish is circulated, and particularly increases in cyclic process and filters operation together.The present invention is that a local microcirculation is set up in corresponding each finish storage tank and a spin finishing differentiation, finish storage tank 1 holds by carrying the stand-by finish of coming between finish, finish storage tank 1 can be adjusted different liquid levels according to spinning oil consumption speed, the about 0.2-1.0M of volume
3, guarantee 2-8 hour consumption, on respective line and operation-interface are arranged; Spinning oil pump 6 is metered fuel charges, according to amount and spinning oil pump 6 specifications that tow need oil, sets the rotating speed of finish pump 6, and the spinning tow only consumes certain finish; The pipeline 2 and 3 of composition local microcirculation can and be finished finish to spinning oil pump 6 fuel feeding and return finish storage tank 1; Filter 4 is to be connected in the pipeline to use. the cleaning of detachably getting off, use repeatedly; Centrifugal circulating pump 5 provides the finish circulation power, and circulating pump 5 specifications can be selected 0.2-1.0M
3/ H, the cycle-index of whole groove finish is 0.2-5.0 time/H.The native system material is a stainless steel, prevents to be corroded by finish or produce new chemical change.The method that filtration is particularly arranged when corrupt initial stage of finish, can filter out putrefaction and bacterium, stop putrefaction to influence production, and bacterium can reduce the corrupt process of finish when constantly filtering out.Through evidence, the method prevents that the corrupt effect of finish is very remarkable, and the current production line that this system of installation is arranged, finish can surpass 1 year and thoroughly not clean, and also corruption can not take place.
The invention has the beneficial effects as follows:
A kind of anti-corrosive method of oil solution of the present invention only needs a spot of material investment and power consumption, guarantee that finish is not corrupt throughout the year, like this, has not only guaranteed the production efficiency of product quality, raising, has also effectively safeguarded equipment, has reduced production cost.
