Abstract
The utility model discloses a heat pipe low temperature evaporator to provide a heat pipe low temperature evaporator which is not prone to over heating, can make the material condensed in a constant low temperature to reduce the time for processing, reduces the heat conducting area and reduces the flow quantity of flow in the circulation of the hot fluid. The tube of the evaporator has a material inlet at the upper part, a material outlet at the lower part, a material heating pipe in the tube, a saturate steam heating pipe at the lower part of the internal shell of the tube, a steam inlet and a steam condensate outlet which are communicated with the saturate steam heating pipe and provided on the tube, and low boiling point solvent around the saturate steam heating pipe as the second phase transition heat transfer medium. The evaporator adopts the saturate steam as the first phase transition thermal storage medium and the low boiling point solvent as the second phase transition heat transfer medium, to improve the situation of the heat transmission, to reduce the process time, to reduce the heat conducting area, to reduce the quantity of flow in the hot fluid circulation, to be less prone to over heating, and to ensure the material is condensed in a constant low temperature.
Description
Technical field
The utility model relates to a kind of evaporation equipment, in particular, relates to a kind of cryogenic vaporizer that adopts the second-order phase transition heat transfer to concentrate thermal sensitivity biologically active material.
Background technology
In existing single-action and the multi-effect evaporator first imitated, and obtains being lower than 100 ℃ saturated vapor difficulty relatively under normal pressure.And in the low temperature concentration process of some thermal sensitivity biological material, heating-up temperature requires to be lower than 100 ℃, and superheating phenomenon easily takes place the water vapour that is higher than 100 ℃, and biological material is lost activity, and therefore, adopts the hot water of no phase transformation as heat transfer medium usually.Because can only utilize the sensible heat of hot water, the thermal efficiency is very low, the hot water circuit amount is big.
The utility model content
The utility model is in order to overcome weak point of the prior art, a kind of difficult generation superheating phenomenon is provided, can guarantees that material is concentrated under constant low temperature, to reduce process time, reduce heat transfer area, reduce the Hot Tube Cryogenic Vaporizer of hot fluid circular flow.
The utility model is achieved through the following technical solutions:
A kind of Hot Tube Cryogenic Vaporizer, comprise evaporator tube, described evaporator tube top is provided with material inlet, described cylindrical shell bottom is provided with material outlet, be provided with the material heating tube in the described cylindrical shell, it is characterized in that the shell side bottom is provided with the saturated vapor heating tube in the described cylindrical shell, be respectively arranged with the water vapour import and the outlet of water vapour lime set that are communicated with the saturated vapor heating tube on the described cylindrical shell; Be provided with low boiling point solvent as the second-order phase transition heat transfer medium around the described saturated vapor heating tube.
Described cylindrical shell is provided with the low boiling point solvent inlet.
The utlity model has following technique effect:
1. in the evaporation operation process, phase-change heat transfer is high efficiency heat transfer type.Evaporimeter of the present utility model is provided with the saturated vapor heating tube in the shell side bottom, low boiling point solvent is arranged as the second-order phase transition heat transfer medium around the saturated vapor heating tube, therefore can be with saturated vapor as the once phase-change heat transfer medium, low boiling point solvent is as the second-order phase transition heat transfer medium, utilize the latent heat of vaporization to carry out concentration operation, heat output is increased substantially, improve the heat transfer property of evaporimeter.Can the augmentation of heat transfer condition, under the prerequisite that guarantees product quality, improve heat transfer efficiency, reduce process time, reduce heat transfer area, reduce the hot fluid circular flow, save electric power, the steady-state evaporation operating condition.
As the low boiling point solvent of second-order phase transition heat transfer medium by the inlet perfusion after, be sealed in the container, safe and reliable, need not to change, add.
3. the low boiling point solvent as the second-order phase transition heat transfer medium has stable vapourizing temperature, is difficult for superheating phenomenon takes place, and can guarantee that material is concentrated under constant low temperature.
4. according to different operation requirements, can make the solvent of different boiling.Satisfy different low temperature concentration operation requirements.
5. new equipment is simple in structure, and processing is simple, easily row.
Description of drawings
Fig. 1 is the structural representation of the utility model Hot Tube Cryogenic Vaporizer.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Fig. 1 is the structural representation of the utility model Hot Tube Cryogenic Vaporizer, comprise evaporator tube 2, evaporator tube top is provided with material inlet 1, the cylindrical shell bottom is provided with material outlet 7, be provided with material heating tube 3 in the cylindrical shell, the shell side bottom is provided with saturated vapor heating tube 5 in the cylindrical shell, is respectively arranged with the water vapour import 8 and the water vapour lime set outlet 6 that are communicated with the saturated vapor heating tube on the cylindrical shell 2.Be provided with low boiling point solvent 4 around the saturated vapor heating tube as the second-order phase transition heat transfer medium.Low boiling point solvent can be that boiling points such as ethanol are lower than 100 ℃ solvent, also can be the mixture that multiple boiling point is lower than 100 ℃ solvent.Saturated vapor heating tube 5 is flooded by low boiling point solvent.
For the ease of maintenance and detection, cylindrical shell 2 is provided with low boiling point solvent inlet 9.
The saturated vapor heating tube is flooded by low boiling point solvent, saturated vapor enters the saturated vapor heating tube by water vapour import 8, heat is discharged to the low boiling point solvent as the second-order phase transition heat transfer medium, discharge by water vapour lime set outlet 6 again after the saturated vapor phase transformation condensation.Low boiling point solvent as the second-order phase transition heat transfer medium is heated back generation vaporization, becomes gas and rises.Thermal sensitivity biologically active material enters in the evaporator tube by charging aperture 1, material heating tube, and the low boiling point solvent heating after being vaporized enters in the separator through material outlet.The low boiling point solvent of vaporization when adding thermal material after material heating tube outer wall phase transformation condensation, the cylindrical shell below of reassembling, periodic duty so automatically.
Because low boiling point solvent has stable vapourizing temperature, and is lower than the material deactivation temperature, be difficult for superheating phenomenon takes place, can guarantee that material is concentrated under constant low temperature.
Although relate to a kind of Hot Tube Cryogenic Vaporizer and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
