Many bio feedstocks are all thermal sensitivity, and process is such as concentrated, dry operation all needs at a lower temperature
It carries out, and can be generally under vacuum conditions, to provide heat with steam or hot water and be concentrated in vacuo or be dried in vacuo；With steaming
Vapour makees heat source, because steam contains huge latent heat, the production capacity of equipment is good, although the mean temperature of material is by vacuum
Degree control, but what the temperature of the contact surface of material and heater was but still determined by vapor (steam) temperature, and steam self-temperature
It is very high, therefore the local temperature of the material of contact heater also can be excessively high, to can be caused to the quality of some heat sensitive materials
It influences；And when using hot water as heat source, although the local temperature of material is not too high, it can guarantee the quality of product, we
Know the only sensible heat that hot water provides, finite energy, so hot water is often relatively low as the heating device production capacity of heat source.
Summary of the invention
In order to overcome the deficiencies of the prior art, the utility model provides a kind of not only can guarantee that heat sensitive material will not be because
The excessively high generation inactivation of temperature, while also can guarantee that the production capacity of equipment is maintained at the steam-to-vacuum low-temperature heat of higher level
Device.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of steam-to-vacuum low-temperature heating device includes that tube still heater, one end are connected to the tube still heater
The steam input pipe of steam inlet, one end are connected to the steam drainage pipe of the steam (vapor) outlet of the tube still heater, are connected to institute
State the hydrophobic cylinder of vacuum of the steam drainage pipe other end；The hydrophobic cylinder of vacuum is connected with vacuum tube, and the vacuum tube is connected with pumping
Vacuum plant；Pressure-regulating valve is installed, the other end of the steam input pipe connects steam generation on the steam input pipe
Device；The Free Float Type Steam Trap and by-passing valve being arranged in parallel are installed on the steam drainage pipe；The vacuum tube and steam are defeated
Enter and be separately installed with the first shut-off valve and the second shut-off valve on pipe, second shut-off valve is located at the steam generation facility and pressure
Between force regulating valve.
As an improvement of the above technical solution, the hydrophobic cylinder of the vacuum is connected with vacuum meter.
Further, pressure gauge is connected on the steam input pipe, the pressure gauge is located at the pressure-regulating valve and column
Between pipe heater.
Further, the tube still heater is internally provided with vapor (steam) temperature detector.
Further, the hydrophobic cylinder bottom of the vacuum is connected with drainpipe, is equipped with drain valve on the drainpipe.
The beneficial effects of the utility model are: the utility model enables to generate Low Temperature Steam in tube still heater, this
The temperature of kind steam is low, but still forgiving has a large amount of latent heat, therefore by this Low Temperature Steam to the temperature-sensitive in tube still heater
Property material be concentrated in vacuo or be dried in vacuo, not only can guarantee that material will not be because of temperature excessively high generation inactivation, while can also protect
The production capacity of card equipment is maintained at higher level.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to Fig.1, a kind of steam-to-vacuum low-temperature heating device of the utility model includes tube still heater 1, one end company
It connects and is connected to 1 steam (vapor) outlet of tube still heater in the steam input pipe 2 of 1 steam inlet of tube still heater, one end
Steam drainage pipe 3, the hydrophobic cylinder 4 of vacuum for being connected to 3 other end of steam drainage pipe；The hydrophobic cylinder 4 of vacuum is connected with very
Blank pipe 5, the vacuum tube 5 are connected with vacuum evacuation device；Pressure-regulating valve 6, the steam are installed on the steam input pipe 2
The other end of input pipe 2 connects steam generation facility；The Free Float Type Steam Trap being arranged in parallel is installed on the steam drainage pipe 3
7 and by-passing valve 8；The first shut-off valve 9 and the second shut-off valve 10, and institute are separately installed on the vacuum tube 5 and steam input pipe 2
The second shut-off valve 10 is stated between the steam generation facility and pressure-regulating valve 6.The workflow of the utility model is as follows:
It first turns on vacuum evacuation device and opens by-passing valve 8 and the first shut-off valve 9, so that being produced in the hydrophobic cylinder 4 of vacuum and tube still heater 1
Raw vacuum, and keep certain vacuum degree；Then, close by-passing valve 8 and from open the second shut-off valve 10, make steam input pipe 2
Steam is inputted into tube still heater 1, then adjust pressure-regulating valve 6 and the first shut-off valve 9 etc. so that the hydrophobic cylinder 4 of vacuum and
Certain vacuum ranges are stilled remain in tube still heater 1, can thus make the steam entered in tube still heater 1
Temperature will be made to reduce because of volume expansion, so that obtaining temperature is lower than the Low Temperature Steam for making heat sensitive material deactivation temperature；It is this
The temperature of steam is low, but still forgiving has a large amount of latent heat, therefore this Low Temperature Steam is to the heat sensitive material in tube still heater 1
When being concentrated in vacuo or being dried in vacuo, it not only can guarantee that material will not be because of the excessively high generation inactivation of temperature, while also can guarantee and setting
Standby production capacity is maintained at higher level；Finally, this Low Temperature Steam is again through steam drainage pipe 3 and Free Float Type Steam Trap 7
After enter in the hydrophobic cylinder 4 of vacuum.
In the present embodiment, specifically, the vacuum degree in the hydrophobic cylinder 4 of vacuum and tube still heater 1 is maintained at -0.07MPa
Left and right, therefore in order to understand the vacuum degree in the hydrophobic cylinder 4 of vacuum in real time, the hydrophobic cylinder 4 of vacuum is connected with vacuum meter 11.And
And specifically, pressure gauge 12 is connected on the steam input pipe 2, the pressure gauge 12 is located at the pressure-regulating valve 6 and column
Between pipe heater 1, to understand the steam pressure of steam input pipe 2 Yu 1 interface of tube still heater in real time.Meanwhile at this
In embodiment, specifically, the vapor (steam) temperature inside tube still heater 1 is most appropriate at 70 degree or so, therefore in order to understand in real time
The temperature of 1 steam inside of tube still heater, specifically, the tube still heater 1 are internally provided with vapor (steam) temperature detector.
With continually entering for steam, steam will be largely condensate in the hydrophobic cylinder 4 of vacuum, for convenience by the hydrophobic cylinder of vacuum
Condensed water in 4 is discharged in time avoids influencing normal heating operation, in the present embodiment, specifically, the hydrophobic cylinder 4 of vacuum
Bottom is connected with drainpipe 13, is equipped with drain valve 14 on the drainpipe 13.
The above is the better embodiment of the utility model, but the utility model is not limited to above-described embodiment,
As long as its technical effect for reaching the utility model with any same or similar means, should all fall into the protection model of the utility model
Within enclosing.
