The invention belongs to liquid phase heat-conduction oil using method in the chemical fibre production.
In the chemical fibre production technology, generally use conduction oil at filter, spinning machine, drawing machine, draw box, reach heat, the purpose of insulation and constant temperature.Existing liquid phase heat-conduction oil uses the process chart of the SUPERSTAPLA of technological process such as Italian FARE company, system is drawn the deep fat in the hot oil by main hot oil pump, a part flows into oil drive back thread by triple valve, another part flows into circular-pump, is input to applying unit (also can claim to use the unit) then; After the input applying unit, a part flows into oil drive back thread by three-way valve, another part is back to the Circulation and Hot Oil Spray pump intake, therefore the deep fat of the output of circular-pump is from two parts: a part is come autonomous hot oil pump, another one refluxes from self, the deep fat mixed proportion that this two parts temperature is different, be to control by the stroke and the aperture of three-way valve, to reach the required temperature of applying unit, and the stroke of three-way valve is controlled by concentrated automatic control system, promptly the actual temperature of applying unit and design temperature deviation signal are input to control system, control system output signal is again controlled the stroke and the aperture of triple valve, thereby the temperature of control circular-pump makes it constant, has also just controlled the temperature of applying unit.This technological process subject matter is: (1) each applying unit all will be prepared a hot oil pump, and power consumption is big, and the energy consumption height increases cost of goods manufactured; (2) be always the output quantity of the circular-pump of applying unit self by the deep fat flow of applying unit, its flow can not be controlled, and causes the circular-pump work done to waste; (3) each applying unit all has the circular-pump of a 15KW, and as SUPETSTAPLEII700-5+5 type production line, one has 15 deep fat applying units, 15 15KW circular-pumps are just arranged, so the device fabrication cost is higher; (4) the operating ambient temperature height of pump, the bearing of motor and pump burns easily, and it is very difficult therefore will to reach long-period stable operation, and maintenance cost is higher.
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of improved liquid phase heat-conduction oil to use technological process.
Main technical schemes of the present invention: remove circular-pump in the technological process of SUPETSTAPLE of Italian company and the pipeline electric control system that is complementary with it, deep fat is directly delivered to each applying unit by main hot oil pump, a part flows into return wire through triple valve before deep fat enters applying unit, a part flows into applying unit, the ratio of its two parts flow is realized the proportioning adjusting by the stroke and the aperture of triple valve, and the stroke of triple valve and aperture are directly to be controlled by centralized control system.
Liquid phase heat-conduction oil of the present invention uses technological process to comprise following process:
1. deep fat flows into hot oil, is higher than 5～8 ℃ of the temperature of applying unit by electrical heating control hot oil temperature;
2. the deep fat after the heating of (1) step is drawn by main hot oil pump, a part flows into oil drive back thread by three-way valve, and another one flows into applying unit, and the ratio of two-part flow is realized by the stroke of control valve;
3. mix with the original deep fat of applying unit by the deep fat amount of (2) step control inflow applying unit, to reach the required temperature of applying unit.
(2) adjusting of described three-way valve stroke of step is to adopt known automatic control system to control, be about to the actual temperature and the temperature error signal input control system of applying unit, control system output signal is again controlled the stroke and the aperture of three-way valve, and then the deep fat that control is drawn by main hot oil pump flows into oil drive back thread and the flowrate proportioning that flows into applying unit, to reach the required temperature of applying unit and to make it constant, concrete control method: when the actual temperature of applying unit is higher than design temperature, the deep fat flow that flows into applying unit reduces, and the deep fat flow that flows into oil drive back thread increases, and actual temperature is descended; When the actual temperature of applying unit was lower than design temperature, the deep fat flow that flows into applying unit increased, and flowed into the deep fat amount minimizing of oil drive back thread, and actual temperature is risen, and so just can reach the required temperature of applying unit and make its constant purpose.The serviceability temperature of conduction oil of the present invention is-28～345 ℃.
Major advantage of the present invention and effect:
1. owing to the circular-pump of each applying unit has been cancelled, therefore power consumption significantly descends, energy consumption reduces, if one production line has 15 applying units, there is a 15KW oil circulating pump in each unit, and the 225KW that per hour can economize on electricity went into operation by annual 7200 hours, every degree electricity is only saved one of the electricity charge every year and is just reached 97.2 ten thousand yuan by 0.60 yuan of calculating.
2. because circular-pump has been cancelled, the maintenance cost of this part has not just had yet, and can guarantee the thermal oil system long-period stable operation.
3. compared with prior art, the pipeline, framework and the electrical control part that reduce by 15 pumps and be complementary with it, thus the device fabrication expense has been descended.
4. simplified control of the present invention, the thermal loss of thermal oil system has also reduced, and the temperature control deviation of applying unit can reach designing requirement ± 1 ℃.
In sum, technological process of the present invention compared with prior art, and is simple to operate, can guarantee the thermal oil system long-term operation, and various expenses all have remarkable decline, thereby the manufacturing cost of product also just descends thereupon.
