Description
Technical field
The present invention is a kind of plasticizing water heat energy recovering method, and a kind of specifically be directed in production process of viscose fiber is moulded
Change the energy recovery technique that groove overflow water is carried out, belong to water-treatment technology field.
Background technology
Plasticizing is one of important procedure of short rayon fiber shaping, plasticizing forming, drawing-off, CS2Evaporation is all in plasticizing groove（Contain
Plasticizing-bath）It is interior to carry out.To ensure plasticizing-bath H2SO4Clean water is provided by import using plasticizing groove in concentration and cleannes, production, gone out
Mouth sets overfall and discharges unnecessary plasticizing body lotion, and resulting plasticizing overflow water temperature control is at 90 DEG C or so, discharge daily
Measure 1200m3Left and right, can produce a large amount of wastes if without energy recovery.Based on this, existing patent document
201410556096.X（A kind of heat energy reuse method for plastifying overflow water, 2014.10.20）A kind of heat energy is proposed to recycle
Method, this method includes carrying out plasticizing overflow water stage-by-stage heat exchange and obtained again delivering to sour station after acid overflow water again and treating
Journey, the heat of plasticizing groove overflow water is fully reclaimed using the mode of heat exchange plasticizing groove supplement water, desulfurization station working solution and cooling water
Can, the indirect heat exchange of plasticizing groove overflow water is realized, during use, inevitable plasticizing overflow water exchanges the shadow of thermal medium
Ring, while plasticizing overflow water still there are 55 DEG C after heat exchange, with energy recovery space.
The content of the invention
Water heat energy recovering method is plastified it is an object of the invention to provide one kind, this method is that steaming is utilized under negative pressure condition
Vapour injector will plastify the vapor that water is produced（Heat）The process taken away, without additional heat exchange medium, can not only take away plasticizing
Amount of heat in water, can also be avoided in the prior art directly using the influence that its impurity exchange thermal efficiency is produced during plasticizing water.
The present invention is achieved through the following technical solutions：One kind plasticizing water heat energy recovering method, overflow is delivered to by plasticizing water
Water collecting tank, the pressure for controlling overflow water collecting tank is that steam injection is set at the top of -93~-90KPa, the overflow water collecting tank
Device, the steam jet ejector mixed zone that the vapor that steam jet ejector produces overflow water storage tank is sent into, after cooling liquid again with it is cold
But discharged after water mixing.
It is 30 that the vapor that the overflow water storage tank is produced obtains temperature in steam jet ejector mixed zone after cooling liquid
~35 DEG C of condensate liquid.
Cooling water mixing section is set, and it is -94~-92KPa to control the pressure in cooling water mixing section, and the cooling water is sprayed
Enter in cooling water mixing section and to be mixed with the vapor of cooling liquid.
The overflow water collecting tank, steam jet ejector mixed zone, cooling water mixing section are sequentially communicated, mixed in the cooling water
Close section and set vavuum pump.
The temperature of the cooling water is 20~25 DEG C,
The cooling water outlet that temperature is 25~30 DEG C is obtained after being mixed after the water vapor condensation liquefaction with cooling water.
Feeding cooling water storage tank after being mixed after the water vapor condensation liquefaction with cooling water, grips water as cut-out and uses.
Plasticizing water in the overflow water collecting tank after steaming vapor, sends into sewage disposal process.
The present invention compared with prior art, with advantages below and beneficial effect：
（1）The inventive method reduces the boiling point of plasticizing water using negative pressure, and the plasticizing water from about 90 DEG C or so of groove of plasticizing is -93
Gasify rapidly under~-90KPa pressure and take away heat, water boiling point is plastified under the pressure can control at 40 DEG C or so, therefore adopt
The temperature that plasticizing water boiling point takes away the plasticizing water after gasification heat simultaneously is reduced with negative pressure, compared with straight using plasticizing water in the prior art
The temperature for connecing the plasticizing water obtained after heat exchange is lower, and energy recovery is more abundant.
（2）The inventive method can be handled the heat that plasticizing water is produced without using extra heat-exchanger rig, led to
Cross and steam jet ejector is set at the top of plasticizing groove, steam is sprayed into by steam jet ejector, what the vapor that plasticizing water is produced was injected into
Steam brings the mixed zone of steam jet ejector into, and is mixed again with cooling water after the cooling liquid of mixed zone, finally gives and can be used for
Cut-out grips the cooling water that water is used.
（3）The inventive method controls overflow water collecting tank in negative pressure shape using simple by steam jet ejector and vavuum pump
State, i.e. -93~-90KPa, while cooling water mixing section is controlled under -94~-92KPa by vavuum pump, by plasticizing groove
Overflow water vapor cools to realize the heat recovery processing of plasticizing water, can avoid in the prior art directly using plasticizing water
When its impurity exchange the thermal efficiency produce influence.
