Description
Technical field
The utility model is related to the evaporation equipment in a kind of pharmaceutical equipment system, especially a kind of MVR evaporation structures.
Background technology
MVR evaporators, also known as mechanical steam recompression evaporator are a kind of novel height for being mainly used in pharmaceutical industry
Energy saving evaporation equipment is imitated, is current international advanced evaporation technique, is the upgraded product for substituting conventional evaporator.
As shown in Figure 1, existing MVR evaporators mainly include vapour compression machine 101, heater 103, the second tube body 104,
Gas-liquid separator 105, vapour compression machine connect heater by the first tube body of steam 102, and heater is connected by the second tube body 104
Ventilation liquid/gas separator 105.Liquid steam is pressurizeed by vapour compression machine, then is heated by heater, is into gas-liquid separator
Gas-liquid separation can be carried out, the gas that wherein gas-liquid separator separates come out comes back to vapour compression machine by third tube body 106
101, the liquid that gas-liquid separator separates come out then is discharged as liquid.The effect of wherein the second tube body 104 is, by both vapor compression
In machine 101 out and pass through the indirect steam that heater 103 heats, by indirect steam by the second quickly blowout of tube body 104,
For eliminating the bubble of liquid level in gas-liquid separator.
But due to being the state close to vacuum in MVR evaporator systems so that the boiling point of water is about 60 DEG C or so,
It is thus not high from the indirect steam of the second tube body 104 blowout.For the less liquid of some foams, it is only necessary to utilize secondary steaming
Quickly wind-force caused by blowout can blow brokenly bubble on liquid level in gas-liquid separator vapour；It is and more for some foams
Liquid for, quickly blown out only according to indirect steam caused by wind-force can not eliminate most of bubble well, thus need
Indirect steam is heated using heater 103, using the relatively high indirect steam of temperature after heating from the second tube body 104
Blowout, high temperature can reduce the surface tension of bubble, make bubble easily by indirect steam blow out caused by wind-force blow brokenly.Profit
The drawbacks of heating indirect steam with heater is：First, heater heats gas, and heat transfer efficiency is low, and energy loss is high；The
Two, indirect steam initial temperature is low, and is limited by heater device size, and effective heating part of heater is generally not
Greatly, thus swiftly flowing indirect steam heating time in heater is shorter, and heater power is limited, leads to two
Secondary steam is not still high in process heater temperature after heating, and the not high indirect steam of temperature can not eliminate gas-liquid separation well
Bubble in device on liquid level.
Invention content
The utility model is directed to a kind of MVR evaporator knots that can effectively improve indirect steam temperature in the second tube body
Structure.
A kind of MVR evaporation structures, including vapour compression machine, heater, gas-liquid separator, steam generator and heat exchange
Device, the first tube body connection vapour compression machine and heater, the second tube body connection heater and gas-liquid separator, equipped with heat exchanger,
At least there are three ports for heat exchanger；The first entrance end of heat exchanger connects the first tube body；The second entrance end connection of heat exchanger is steamed
The outlet conduit of vapour generator；The port of export of heat exchanger connects the second tube body.
Due to being provided with heat exchanger, and pass through heat exchanger and the indirect steam of primary steam and the second tube body exchange heat,
Improve the enthalpy of indirect steam；The indirect steam for being enhanced enthalpy is quickly blowed and sprayed to gas-liquid separator and eliminates the gas on liquid level
Bubble, can reduce bubble surface tension, quick indirect steam can eliminate bubble well due to its temperature is higher；And it utilizes
Temperature higher primary steam heats the indirect steam in the second tube body, eliminates working well for bubble.

Specific embodiment
As shown in Figures 2 and 3, this MVR evaporators include vapour compression machine 101, heater 103, the second tube body 104, gas
Liquid/gas separator 105, steam generator, liquid enter vapour compression machine 101, and the outlet side of vapour compression machine passes through the first tube body
The first entrance end of 102 connection heaters 103, the port of export of heater 103 connect gas-liquid separator by the second tube body 104
105, the gas that gas-liquid separator 105 is isolated flows back into vapour compression machine through third tube body 106, and gas-liquid separator 105 detaches
The liquid outflow MVR evaporators gone out, set heat exchanger 207, at least there are three port, the first entrance ends of heat exchanger for heat exchanger
308 the first tube bodies 102 of connection, the port of export 311 of heat exchanger connect the second tube body 311, and the second entrance end 310 of heat exchanger connects
The outlet conduit of steam generator, first entrance end 308, the port of export 311 and the second entrance end place pipeline section of heat exchanger are all provided with
There is valve, the second entrance end 310 of heat exchanger 207 connects the air outlet pipe of steam generator, primary steam is generated in steam generator
Vapour, i.e. vapor.
Liquid stoste becomes indirect steam, then after being heated by heater by vapour compression machine pressurization, indirect steam into
Gas-liquid separation can be carried out by entering gas-liquid separator.Wherein gas-liquid separator separates come out gas by third tube body 106 again
Vapour compression machine 101 is returned to, the liquid that gas-liquid separator separates come out then is discharged as liquid.The wherein work of the second tube body 104
With being, by vapour compression machine 101 out and pass through the indirect steam that heater 103 heats, indirect steam is passed through second
Tube body 104 is quickly blown out, for eliminating the bubble of liquid level in gas-liquid separator.The heat exchanger 207 of the utility model setting, effect are
The indirect steam that sub-fraction comes out from vapour compression machine 101 is diverted in heat exchanger 207, then by heat exchanger second entrance
End 310 introduces in boiler the primary steam for generating relatively-high temperature, to heat the indirect steam out of second tube body.And due to MVR
It is the structure of similar pipe heat exchanger in evaporator, primary steam and indirect steam can exchange heat but not be mutually mixed；Second
The temperature of indirect steam is sufficiently high to reduce the tension of bubble surface in tube body, and the second tube body 104 is quick to gas-liquid separator 105
The indirect steam of relatively-high temperature is blown out, can effectively eliminate the bubble in gas-liquid separator 105 on liquid level, and indirect steam
Essence is all liquid, because without bringing impurity on liquid or influencing its concentration.If in addition, liquid generate foam compared with
When less, without using heat exchanger 207, the valve of pipeline section where heat exchanger first entrance end, the port of export, second entrance end can be closed
Door 309, the utility model can be used as common MVR evaporators and use.
It is noted that being passed through the primary steam pressure of heat exchanger in 0.05~0.15MPa, MVR inner liquid medicine temperature is 90~99
DEG C, vacuum degree is in -5kpa~-30kpa.
Further, in order to provide better seal performance, the second entrance end of the heat exchanger, the port of export, first enter
Valve on mouth end is butterfly valve.
Further, in order to ensure the cleanliness factor for entering the primary steam in heat exchanger 207, the pipe where second entrance end
Vapor filter is set on road, and the both ends of vapor filter connect respectively with second entrance end and steam generator.
