Embodiment 1

[0020] A. Feed the fibers refined by the refining machine into the wet opener for wet opening, and then enter the cotton collecting box of the wet opener;

[0021] B. Heat the waste hot air with a temperature of 40°C and a humidity of 45% of the rotary screen dryer through the heater to form hot and humid air with a temperature of 55°C and a humidity of 30%, and then enter the cotton collection box and the cotton collection box The fibers are sent to the separator through the fan; the heater is heated by the waste heat of the water drained from the drying trap;

[0022] C. During the above process, the hot air absorbs moisture, and the fiber is separated from the hot and humid air in the separator, and then it enters the first wool feeder and then is dried with a dryer, and the waste heat air of the dryer enters the heater in step B.

Embodiment 2

[0024] A. Feed the fibers refined by the refining machine into the wet opener for wet opening, and then enter the cotton collecting box of the wet opener;

[0025] B. Heat the waste hot air with a temperature of 50°C and a humidity of 50% of the rotary screen dryer through the heater to form hot and humid air with a temperature of 65°C and a humidity of 40%, and enter the cotton collection box and the cotton collection box The fibers are sent to the separator through the fan; the heater is heated by the waste heat of the water drained from the drying trap;

[0026] C. During the above process, the hot air absorbs moisture, and the fiber is separated from the hot and humid air in the separator, and then it enters the first wool feeder and then is dried with a dryer, and the waste heat air of the dryer enters the heater in step B.

Embodiment 3

[0028] A. Feed the fibers refined by the refining machine into the wet opener for wet opening, and then enter the cotton collecting box of the wet opener;

[0029] B. Heat the waste hot air with a temperature of 45°C and a humidity of 46% of the rotary screen dryer through the heater to form hot and humid air with a temperature of 60°C and a humidity of 35%, and enter the cotton collection box and the cotton collection box The fibers are sent to the separator through the fan; the heater is heated by the waste heat of the water drained from the drying trap;

[0030] C. During the above process, the hot air absorbs moisture, and the fiber is separated from the hot and humid air in the separator, and then it enters the first wool feeder and then is dried with a dryer, and the waste heat air of the dryer enters the heater in step B.

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 [0001] The invention relates to a production process of viscose fiber, more specifically, the invention relates to a drying process in the production of viscose fiber. Background technique [0002] At present, the drying process in the production of viscose fiber mainly relies on the rotary screen dryer. The principle is: after the hot air is heated by steam through the radiator, the negative pressure is generated by the fan to adsorb the fiber on the surface of the rotary screen, so that the wind passes through the adsorption on the circular screen. The silk layer on the surface of the net produces circulation. During the circulation process, the hot air exchanges heat with the fiber to heat up the fiber; the hot air takes away the moisture of the fiber, and the humid air is emptied through the dehumidifying air duct to achieve the purpose of drying. [0003] The current existing technology is improved by the following methods: [0004] 1. Increase the dryi...
