Abstract
The utility model is a kind of low-boiling-point substance retracting device.Include evaporator, vavuum pump, condenser, receiving tank, the feed(raw material)inlet of its intermediate pump and the material outlet of evaporator are connected, and the material outlet of vavuum pump is connected with condenser feed(raw material)inlet, and the material outlet of condenser is connected with receiving tank.Low-boiling-point substance retracting device of the present utility model, raw material is isolated gas phase from evaporator (negative pressure) and entered in vavuum pump, condenser (normal pressure) is discharged into by vavuum pump again, vapor condensation is stored in receiving tank by condenser into liquid phase, material is condensed at ambient pressure, tens degree higher than material condensation point under negative pressure of material condensation point is even more more under normal pressure, and condensation point is more high to be more easily condensed into liquid phase, and the utility model less energy consumption, the low-boiling-point substance rate of recovery are high.
Description
Technical field
The utility model is a kind of low-boiling-point substance retracting device, belongs to the renovation technique of low-boiling-point substance retracting device.
Background technology
In chemical process, frequently encounter needs and different boiling component separated, and using it is most be vacuum point
Evaporate.Vacuum topping device is made up of evaporator, condenser, receiving tank, vavuum pump, exhaust gas processing device.（We are evaporation below
What is be evaporated in device is mutually low-boiling-point substance, and residual is mutually high-boiling components.）
Under certain vacuum degree, the boiling point of low-boiling-point substance is compared with normal pressure reduction.Especially to improve separating effect, high vacuum is used
In the case of, low-boiling-point substance boiling point is greatly reduced, therefore condenser needs area increased, refrigerant temperature need to lower, refrigerant circulation
Amount is bigger could to be condensed into low-boiling-point substance liquids recovery, and remains the more low-boiling-point substance that is not condensed, enter vavuum pump with gaseous state
And exhaust gas processing device, vent gas treatment load is significantly greatly increased, and cause material loss.
The content of the invention
The purpose of this utility model is to consider above mentioned problem and provide a kind of low-boiling-point substance retracting device.The utility model exists
Low-boiling-point substance is condensed under normal pressure, saving energy consumption is reached, material loss is reduced, vent gas treatment load is reduced, the discharge of sewage waste gas is reduced
Effect.
The technical solution of the utility model is：Low-boiling-point substance retracting device of the present utility model, includes evaporator, vacuum
Pump, condenser, receiving tank, the feed(raw material)inlet of its intermediate pump and the material outlet of evaporator are connected, the material outlet of vavuum pump
It is connected with condenser feed(raw material)inlet, the material outlet of condenser is connected with receiving tank.
Low-boiling-point substance retracting device of the present utility model, raw material isolates gas phase from evaporator (negative pressure) and enters vavuum pump
In, then condenser (normal pressure) is discharged into by vavuum pump, vapor condensation is stored in receiving tank by condenser into liquid phase, and material is in normal pressure
Tens degree higher than material condensation point under negative pressure of material condensation point is even more more under lower condensation, normal pressure, and condensation point is more high more easy to be cold
Liquid phase is congealed into, the utility model less energy consumption, the low-boiling-point substance rate of recovery are high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment：
Structural representation of the present utility model is as shown in figure 1, low-boiling-point substance retracting device of the present utility model, includes evaporation
Device 1, vavuum pump 2, condenser 3, receiving tank 4, the feed(raw material)inlet of its intermediate pump 2 are connected with the material outlet of evaporator 1, vacuum
The material outlet of pump 2 is connected with the feed(raw material)inlet of condenser 3, and the material outlet of condenser 3 is connected with receiving tank 4.
In the present embodiment, above-mentioned receiving tank 4 is also associated with exhaust gas processing device 5.
Operation principle of the present utility model is as follows：Operation principle of the present utility model is as follows：Raw material is separated from evaporator 1
Go out gas phase to enter in vavuum pump 2, raw material is in negative pressure state, then is discharged into condenser 3 by vavuum pump 2, and raw material is in normal pressure
Vapor condensation is stored in receiving tank 4 by state, condenser 3 into liquid phase, and tail gas is handled through exhaust gas processing device 5.Material is at ambient pressure
Condensation, tens degree higher than material condensation point under negative pressure of material condensation point is even more more, and condensation point is more high to be more easily condensed into liquid phase,
Less energy consumption, the low-boiling-point substance rate of recovery are high.
170 DEG C of low-boiling-point substance atmospheric boiling point, it is not necessary to cooled down under vacuum, 400kg containing low-boiling-point substance in 5 tons of raw materials, condenser is changed
Hot area 5M2, originally water cooling, oil-free claw vavuum pump 4KW, tail gas alkaline cleaning charcoal absorption.
New equipment processing procedure and consumption：Low-boiling-point substance 385kg ~ 390kg is an actually-received, per batch originally water consumption about 1
Ton（It can be recycled）, it is not required to change pumping fluid, 100 batches need to replacing alkali lye, 100 crowdes of replacing activated carbon 100kg.
Low-boiling-point substance, high-boiling components can be one-component, can be various ingredients composition.Evaporator 1 can according to material characteristic
To heat, it can also freeze with normal temperature and carry out separate fraction.
