Abstract
The invention relates to a method for removing bubbles in the production process of viscose fiber, which belongs to the technical field of chemical industry. The method uses a three-stage steam spraying system to reduce the pressure of a viscose fiber system in a continuous deaeration working section in the production process of the viscose fiber, and heats the viscose fiber system directly by using the tail steam which is not cooled in the third stage steam spraying system. The annual yield of 100, 000 tons of the viscose fiber is taken as an example, the steam consumption is 1.5 tons per hour, the tail steam in the second stage steam spraying system is directly adopted to completely meet the requirement of the embodiment, and the steam discharge is reduced by 12, 600 tons; at the same time, 30, 000 tons of cooling water is saved and the energy consumption of other devices in the whole flow is greatly reduced.
Description
Technical field
The present invention relates to remove in a kind of production process of viscose fiber the method for bubble.
Background technology
Viscose belongs to regenerated celulose fibre.It is to be raw material with the native cellulose, makes the soluble cellulose xanthate acid through operations such as alkalization, experienced, yellows, is dissolved in sig water again to make viscose glue, makes through wet spinning.Adopt different raw material and spinning technique, can obtain common viscose fiber respectively, koplon and high tenacity staple fibre etc.In the dissolving and viscose glue hybrid filtering course of conveying of sodium cellulose xanthate, entrained air inevitably in the viscose glue causes the big and small bubble that is scattered here and there in the viscose glue.For making spinning smooth, must carry out evacuation of viscose, deaeration is now used under the vacuum state and is carried out, and for guaranteeing the requirement of high vacuum, the general steaming spray system that adopts vacuumizes.The power consumption height of said method, and program complexity, the de-bubble effect is relatively poor, and equipment breaks down easily.
Summary of the invention
The invention solves problems such as existing in prior technology power consumption height, equipment complexity, the method for removing bubble in a kind of production process of viscose fiber is provided.
Above-mentioned technical purpose of the present invention solves by the following technical programs:
Remove the method for bubble in a kind of production process of viscose fiber, utilize three grades to steam the pressure that the spray systems reduce the viscose systems in the continuous deaeration workshop section in the production process of viscose, and the third level is steamed the tail vapour of spray system direct heating viscose system when uncolled.
The viscose semi-finished product will be removed the bubble in the viscose system before entering spinning technique, otherwise the situation that can occur fracture of wire in the process of spinning greatly influences serialization production.Removing the pressure that the method for bubble adopts the low pressure method of giving vent to anger promptly to reduce the viscose system usually spins off gas from the viscose system, the general employing steamed the pressure that the spray system reduces the viscose system, need take three grades to steam the spray system in order to reach the target vacuum degree, this needs a large amount of steam of consumption, in every grade steaming spray system, also need a large amount of cooling waters to cool off simultaneously to steaming the spray system, the steam of afterbody is directly emptying usually after water quench, and this is the pollution that a kind of great waste has also caused environment.The proposition of the present invention innovation a kind ofly adopt three grades of step-down methods of steaming spray, promptly steam the conventional cooling water of cancellation in the spray system the 3rd, and directly being heated viscose, the exhaust steam of the third level make the temperature of viscose system raise, the present invention utilizes the steam of the discharge of the third level to make the temperature of viscose system rise, gas is more prone to discharge in the viscose, the present invention has simultaneously reduced the consumption of cooling water, and the method for using three grades of steaming spray systems and heating the viscose system has reached the purpose that eliminates of viscose bubble.
Adopt technical scheme of the present invention, when reducing equipment, reduced the consumption of cooling water, thereby the step that has reduced steam discharging has reduced the infringement to environment.
As preferably, in the appearance of viscose system the hot water barrel is installed, utilize the Steam Heating hot water barrel, the hot water heating viscose system among the hot water barrel.Utilize its heat-transfer effect of this system better, steam indirect viscose system, the exchange efficiency height of heat, speed is fast.
As preferably, insert exhaust system on the described hot water barrel.Exhaust system has quickened the rate of heat exchange of steam, can significantly improve the temperature of viscose system.
Therefore, it is low that the present invention has power consumption, and equipment is simple, characteristics such as energy-conserving and environment-protective.
The specific embodiment
Below by specific embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1:
Remove the method for bubble in a kind of production process of viscose fiber, utilize two-stage to steam the pressure that the spray system reduces the viscose system in the continuous deaeration workshop section in the production process of viscose, and the tail vapour that the third level is steamed the spray system is directly heated the viscose system.Natural former slip cypress is alkalized successively, experienced, operations such as yellow are made the soluble cellulose xanthate acid, be dissolved in sig water again and make viscose glue, viscose glue is squeezed in the continuous deaerator with pump, deaerator is connected and is steamed the step-down of spray system continuously, described steaming spray system is three grades, preceding two-stage is steamed the spray system and is adopted water quench, the third level is steamed the spray system overlays on the appearance of continuous deaerator for the tail vapour access package of cooling hot water barrel, hot water barrel's the other end inserts exhaust system, exhaust system has been accelerated the heat exchange of heat transfer medium among steam and the hot water barrel, present embodiment is produced 100000 tons of viscoses per year, need 1.5 tons/hour of consumption steam, directly the steam tail vapour of the secondary steaming spray system among employing the present invention can satisfy the requirement of present embodiment fully, reduces discharging 12600 tons of steam simultaneously.Save about 30000 tons of cooling water simultaneously, greatly reduce the power consumption of whole other equipment of flow process simultaneously.
