Fig. 1 is according to a kind of multi-heat source vacuum distillation plant schematic diagram depicted in some embodiments of the invention.In figure
Shown in, the multi-heat source vacuum distillation plant 100 that disclosed herein, include a distillation bucket 120, it connects a condenser 110,
Condenser 110 then connects a choke valve 130, and choke valve 130 connects a multi-heat source vaporizer module 140, multi-heat source vaporizer
Module 140 connects a compressor 150, and compressor 150 connects condenser 110.
Owing to known vacuum distillation plant operating condition can be the most limited at part stage, so that being in low-energy-efficiency condition
Operating, such as to the heating period of material in distillation bucket when equipment just starts, owing to condenser need to provide heat to meet material
The demand of target temperature is risen to by room temperature, but, now heat produced by compressor is minimum, causes distilling apparatus to be in one
The operating condition of low usefulness, therefore too increases the heat time heating time needed for distilling apparatus.
The multi-heat source vacuum distillation plant 100 of the present invention utilizes the thermodynamic cycle of compressor 150 to produce mobile heat energy
Effect, be effectively improved many by compressor 150, condenser 110, choke valve 130 with the combination of multi-heat source vaporizer module 140
The efficiency of thermal source vacuum distillation plant 100 so that therefore production cost can also reduce, simultaneously because effectively utilize in factory
Produced additional thermal energy, more can reduce the temperature of working environment, improves the work efficiency of employee.
Refering to Fig. 1, being full of coolant in the pipeline of the compressor 150 of the present invention, the compression of refrigerant vapor machine 150 by compression produces
The refrigerant vapor of High Temperature High Pressure.After coolant steam flows into condenser 110, condense into condensed fluid because of heat extraction, now arranged
The heat gone out can add the material in thermal distillation bucket 120 effectively, makes the temperature of material increase, with by the material vaporization of part.And
Coolant then travels further into choke valve 130, flashes to refrigerant vapor subsequently in multi-heat source vaporizer module 140, and produces
Endothermic effect.
Thermal source needed for the endothermic effect of multi-heat source vaporizer module 140 is it may be that the such as first vaporizer 142 is provided
A thermal source, the heat of material of the vaporization of distillation bucket 120, enter the first vaporizer 142 via pipeline and make its temperature reduce into
It is a liquid, and enters storage in tank 160.Thermal source needed for the endothermic effect of multi-heat source vaporizer module 140 is permissible
It is, the thermal source that the such as second vaporizer 144 is provided, that is other useless recovery thermal source, can be produced in processing procedure
High temperature waste liquids etc., other processing procedures in factory are produced unnecessary heat reclaims, and e.g. in machine room, high temperature air reclaims
Thermal source.Thermal source needed for the endothermic effect of multi-heat source vaporizer module 140 is it is also possible that the such as the 3rd vaporizer 146 is provided
A thermal source, that is surrounding air thermal source, it comes from and maintains thermal source produced by the operating temperature of general normality in factory, no
Multi-heat source vacuum distillation plant 100 only can be provided can to provide employee work one suitable operating temperature simultaneously.3rd evaporation
Device 146 can absorb this air heat source to be reduced air themperature, needed for making to be more suitable for work, and steams after being absorbed by this thermal source
Evaporate the heating of material in bucket 120.
Refrigerant vapor can be sucked by compressor 150 again, repeats compression, to constitute a closed circuit.Whole circulation makes
Obtain heat to be absorbed at multi-heat source vaporizer module 140, be then discharged to add in thermal distillation bucket 120 at condenser 110
Material.
The multi-heat source vaporizer module 140 of the present invention also includes a vacuum pump 170, with required in maintaining distillation bucket 120
Vacuum, be effectively reduced the temperature needed for distillation, and then improve the efficiency of distillation.
It is the control method according to a kind of multi-heat source vacuum distillation plant depicted in some embodiments of the invention refering to Fig. 2
Schematic diagram.As it can be seen, the control method of the multi-heat source vacuum distillation plant of the present invention, in step 210, concentration processes starts
After, first step 220, vacuum pump is started.Then, step 230, further heat pump is started.This heat pump and including in Fig. 1
Condenser 110, choke valve 130, multi-heat source vaporizer module 140 and compressor 150.
Then, step 240 is entered, it is judged that in distillation bucket, whether have distillation bucket condensation to reclaim thermal source.If being judged as YES, i.e. steam
Evaporate bucket condensation and have recovery thermal source, then enter step 250, start the first vaporizer circulation, use the first vaporizer to carry out thermal source
Reclaim.If being judged as NO, i.e. reclaiming thermal source without distillation bucket condensation, entering step 260, further determined whether that other give up and reclaimed
Thermal source, high temperature air or other recyclable thermal source in e.g. one high temperature devil liquor recovery thermal source, machine room.
If being judged as YES, i.e. there are other useless thermals source that reclaims, then entering step 270, starting one second vaporizer circulation.If sentencing
It is no for breaking, and i.e. reclaims thermal source without distillation bucket condensation, utilizes surrounding air to reclaim thermal source, enter step 280, starts one the 3rd evaporation
Device circulation is to carry out distilling the distillation of material in bucket, that is to maintain heat produced by general work ambient temperature, steams
Evaporate the distillation of material in bucket.
Its intermediate pump can provide the vacuum needed for distillation bucket, reduces the temperature needed for distillation, promotes distillation
Efficiency.
Then, step 290, persistently judge whether the material of distillation bucket reaches required concentration, if not yet reaching required
Concentration, the most persistently carries out distilling and repeat above-mentioned judgement, to select optimal thermal source and vaporizer circulation, to promote frequent fever
The efficiency of source vacuum distillation plant.
When reaching required concentration or having reached the moisture storage capacity of needs, enter step 300 and close heat pump, step 310 vacuum
Pump cuts out, and step 320 terminates concentration processes.
In sum, the multi-heat source vacuum distillation plant in the present invention and control method thereof can utilize multi-heat source vaporizer
Module properly selects suitable thermal source and carries out the origin of heat of vacuum distillation plant so that the efficiency of vacuum distillation plant is able to
Promote, more can reduce production cost, can simultaneously be effectively utilize produced additional thermal energy, maintenance work environment in factory
Temperature, improve employee work efficiency.
Although the present invention is disclosed above with embodiment, so it is not limited to the present invention, and any this area tool is logical
Often skill, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations, the therefore protection of the present invention
Scope is when being defined in the range of standard depending on appending claims.
