Abstract
The invention relates to a drying process during the viscose production, which can improve the drying capability to solve the problem that the improvement of the drying capability is limited by various reasons and can not be improved in prior art. In the invention, working procedures are added between wet cotton opening and a feeder, and waste hot air discharged during the drying passes through a heater to heat the fiber so as to achieve the purpose of reducing the water content of the fibers; therefore, 3-5% of water content of the fibers after the wet cotton opening is reduced, and the yield is greatly increased.
Description
Technical field
The present invention relates to a kind of production technology of viscose, more particularly, the present invention relates to a kind of viscose in producing stoving process.
Background technology
Stoving process in the viscose production at present mainly relies on rotary screen drier; Its principle is: hot blast is after steam passes through radiators heat; Produce negative pressure with blower fan fiber is adsorbed on the cylinder surface; Make wind produce circulation through being adsorbed on the surperficial silk layer of cylinder, hot blast and fiber carry out heat exchange in cyclic process, make the fiber heat temperature raising; Hot blast is taken away the moisture content of fiber, and humid air passes through the emptying of hydrofuge airduct, thereby reaches the purpose of oven dry.
Prior art is improved through following method at present:
1, improves bake out temperature: improve bake out temperature and will improve steam pressure and temperature exactly, and the boiler production capacity has restricted the raising of steam pressure and temperature;
2, improve cylinder hot blast air quantity and area of dissipation: can increase area with increase cylinder quantity through improving rotation speed of fan raising hydrofuge amount; But must increase plant area like this; Increased production cost, rotation speed of fan improves unavoidable take place vibration and burning, stays potential safety hazard;
3, reduce slubbing feeder fiber moisture: can pass through to increase the pressure of padding machine, but DeGrain can only be considered to reduce fiber moisture through extraneous approach.
Summary of the invention
The raising that the present invention is intended to solve drying capacity in the above-mentioned prior art receives the restriction of various reasons, and the problem that can not improve provides a kind of viscose to improve the stoving process of drying capacity in producing.
In order to realize the foregoing invention purpose, concrete technical scheme of the present invention is following:
Stoving process during a kind of viscose is produced is characterized in that: comprise following processing step:
A, fiber is sent into wet opener, the opener that wets is accomplished the collection hopper that the back gets into the opener that wets;
After fiber got into wet opener, the wet cotton-slitting beater strike fiber that runs up carried out opener with fabric thrashing, helps oven dry, reduces wet group;
B, the used heat air of dryer is formed damp-heat air through heater heating back, get into the collection hopper, the fiber in the collection hopper is delivered to separator through blower fan;
Hot blast moisture absorption in C, the said process, fiber separates with damp-heat air in separator, Tumblies Dry behind the entering slubbing feeder again, and the used heat air of dryer gets into the heater of step B.
The temperature of the used heat air among the above-mentioned steps B is 40-50 ℃, and humidity is 45-50%.
The temperature of the damp-heat air among the above-mentioned steps B is 55-65 ℃, and humidity is 30-40%.
Heater is that the waste heat that utilizes the oven dry steam trap to dredge water outlet heats among the above-mentioned steps B.
The useful technique effect that the present invention brings:
Between wet opener and feeder, increase operation, the used heat wind that utilizes oven dry to discharge heats up fiber through heater to reach the purpose that reduces moisture, has reduced fiber moisture 3-5% behind the wet opener, and output is increased considerably.
