Abstract
A kind of chemical fibre chips drying process, the following steps are included: (1) carries out level-one dehumidification to sucking wind using drying machine, air is after overcompression, the air themperature after freezing is reduced to≤4 DEG C by reducing chilled water temperature, water content is reduced to 35% in air after freezing, chilled water temperature≤12 DEG C；(2) second level dehumidification is carried out to the dry air after level-one dehumidification using low-grade fever regenerative drying machine and lithium chloride moisture eliminator, the oil mixing with water steam of air remnants is removed by oil mist filter, the regeneration wind-warm syndrome of low-grade fever regenerative drying machine is controlled at 90~115 DEG C, Boiler pressure control is regenerated in 18~22Nm, 3/min, passes through dry air dew point≤- 100 DEG C obtained after second level dehumidification.The present invention makes slice energy evenly drying, improves production efficiency by continuing to optimize transformation to section drying process and chip drying process.
Description
Technical field
The invention belongs to textile technology fields, and in particular to a kind of chemical fibre chips drying process.
Background technique
For slice spin for, slice be exactly experimental branch line raw material, and the quality of chip drying directly influence it is subsequent
Steady production.At present there are many kinds of the domestic section drying process used, several is domestic from foreign countries' introduction, but in recent years
Also there is the exploitation of new equipment.It is also more next to the dry requirement of slice with the continuous development of the fibres in differentiation such as high F, super fine denier
It is higher.
Now, vacuum drying and pneumatic conveying drying are mostly used in the drying of slice both at home and abroad, drying equipment mainly has KF
Formula drying equipment, Bu Leshi (BM) drying equipment, Ji Mashi drying equipment, river field formula drying equipment, come new-type drying equipment,
Pleiotaxy drying equipment etc..Since drying mode or equipment are different, therefore its process flow, process conditions and operation notice etc.
There is difference, but drying principles are essentially identical, and these dry technologies all tend to be mature.But with advances in technology, people
Quality of life raising so that also higher and higher to the requirements such as clothes are worn, this makes us need to produce various uses
Polyester filament, as superfine denier fiber, porous yarn, Silk, shaped filaments etc., these production difficulty is mentioned than the difficulty of conventional silk
High very much, this brings very big challenge to our technical study.It spins normal to the quality requirement ratio of chip drying when these
It is high to advise spinning, generally requires dry sliced moisture content in 25ppm or less.In order to ensure spinning quality and spinning production are normal,
It needs constantly to optimize transformation to section drying process and chip drying process.The drying equipment of early stage such as K.F company
The fill-type drying equipment of production haves the shortcomings that moisture content is high after chip drying and it is big to fluctuate, is unable to satisfy terylene
The production of FDY fine denier filament.
Traditional drying mode, drying equipment are unable to satisfy the dry of polyester FDY fibre in differentiation slice and require, and cause to cut
Moisture content is higher after piece is dry and fluctuation is big.Transformation is continued to optimize to drying device, increases refrigerator, improves first order dry wind
Dehumidification ability, select reasonable dry intake and inlet air temperature, keep dry mass reliable and stable, tend to drying process more
Rationally, so that dry chip be made to meet production requirement.
Summary of the invention
In order to solve the problems, such as to appear above, the invention adopts the following technical scheme: a kind of chemical fibre chips drying process, packet
Include following steps:
(1) level-one dehumidification is carried out to sucking wind using drying machine, air, will be cold by reducing chilled water temperature after overcompression
Air themperature after jelly is reduced to≤4 DEG C, and water content is reduced to 35% in the air after freezing, chilled water temperature≤12 DEG C
；
(2) second level is carried out to the dry air after level-one dehumidification using low-grade fever regenerative drying machine and lithium chloride moisture eliminator to take off
It is wet, the oil mixing with water steam of air remnants is removed by oil mist filter, by the regeneration wind-warm syndrome control of low-grade fever regenerative drying machine
At 90~115 DEG C, regeneration Boiler pressure control is revealed in 18~22Nm, 3/min by the dry air obtained after second level dehumidification system
Point≤- 100 DEG C；
(3) dehumidification is carried out to dry air again using drying machine, until the water content in air is reduced to 25% or less；
(4) air after step 3 dehumidification is passed through in drying tower dry chemical fibre chips, the dry sky obtained after the second level dehumidification
The intake of gas is 500~580m, 3/h, and inlet air temperature is 186~192 DEG C, and chemical fibre chips stop in drying tower
Staying the time is 8~10h, obtains moisture content and stablizes dry chip in≤18ppm.
Further, dry air is after the secondary dehumidification of step (2), since low-grade fever regenerative drying machine is with certain temperature
Degree, can condense droplet, therefore step (2) dehumidification effect is unobvious, can only play the role of deoiling when encountering 4 DEG C of air below,
Therefore the aqueous vapor under dehumidification in air guarantees drying effect to step (3) again.
The utility model has the advantages that the present invention makes to be sliced energy by continuing to optimize transformation to section drying process and chip drying process
Evenly drying improves production efficiency.
