Detailed description of the invention
For being better understood from technique scheme, below in conjunction with the accompanying drawings in specific embodiment the present invention is done further
Explanation.
As it is shown in figure 1, a kind of tea polyphenols ethanol eluent that is applicable to reclaims the 2nd effect evaporator system concentrated, including one-level
Vaporizer and secondary evaporimeter；Wherein, described one-level vaporizer includes primary heater 1 and one-level vaporization chamber 2, primary heater
1 upper end is connected with one-level vaporization chamber 2 by pipeline, is connected by the bottom of pipeline with primary heater 1 bottom one-level vaporization chamber 2
Connecing, primary heater 1 upper end is provided with steam inlet 8.
Described secondary evaporimeter includes secondary heater 3 and dual evaporation room 4, secondary heater 3 top by pipeline with
Upper end, dual evaporation room 4 connects, and is connected bottom secondary heater 3 by pipeline bottom dual evaporation room 4.
Described one-level vaporization chamber 2 upper end is connected with secondary heater 3 by pipeline；Described secondary heater 3 lower end is provided with
Feed liquid port 5, is provided with material liquid outlet 7 bottom described one-level vaporization chamber 2；Described secondary heater 3 and the bottom of dual evaporation room 4
It is connected with side, one-level vaporization chamber 2 lower end also by pipeline.Tea polyphenols ethanol eluent is entered secondary heater by feed liquid port 5
In 3, heating, after being evaporated subsequently into dual evaporation room 4, carries out heating evaporation in entering back into one-level vaporization chamber 2.Due to wine
Essence evaporates recovery in two effect vaporization chambers 4 the most in a large number, and the material alcohol concentration entering one-level vaporizer declines to a great extent, thus warp
Gas temperature after one-level vaporizer heating evaporation just increases, and it is made thermal source and enters secondary heater 3, then material is prone to steam
Send out, add that the evaporating temperature of ethanol is lower than water, thus two effect evaporations are stable and reliable in work, and a because operating temperature relatively effect
Low, so being also not easy to run material.
Upper end, described dual evaporation room 4 is connected by pipeline and a condenser, and described condenser includes first-stage condenser 9 He
Secondary condenser 10, described first-stage condenser 9 is connected with secondary condenser 10.Wherein to be provided with room temperature cold in first-stage condenser 9 upper end
But water inlet 91, lower end is provided with room temperature coolant outlet 92, and the cooling water temperature used by first-stage condenser 9 is room temperature；Described two
Level condenser 10 upper end is provided with sub-cooled water inlet 101, and lower end is provided with sub-cooled water out 102, secondary condenser 10 institute
Cooling water temperature≤10 DEG C.Preferably, the area of described first-stage condenser 9 is more than the area of secondary condenser 10.One
Level condenser 9 and secondary condenser 10 are tubular type or plate-type condenser.Configuration secondary condenser 10, it is easy to the condensation of ethanol is returned
Receiving, second level condenser 10 uses low-temperature cooling water, has the most more ensured that the condensation of ethanol is reclaimed, and alcohol recycle rate can ensure that >=
98%.
Pipeline bottom described secondary heater 3 and between one-level vaporization chamber 2 lower end is provided with a material pump 6, this material pump 6 energy
The enough conveying liquid in pipeline toward one-level vaporization chamber 2 direction provides power.Described secondary condenser 10 is provided with a vacuum pump
11, the combined system of first-stage condenser 9 and secondary condenser 10 can be carried out evacuation, in higher vacuum by this vacuum pump 11
Under carry out the alcohol recycle of tea polyphenols ethanol eluent and material concentrates.
The present embodiment uses 2nd effect evaporator to carry out alcohol recycle and material concentration, the whole mistake of tea polyphenols ethanol eluent
Journey stability, persistence are preferable；Due to the indirect steam produced when the thermal source of secondary heater 3 employing is material evaporation, therefore
Whole system is energy-conservation compared with single effect evaporator, and system energy consumption is about the 45% of single effect evaporator.Additionally, because material stops in system
Time shortens, and can improve tea polyphenols product quality.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for a person skilled in the art,
On the premise of without departing from present configuration, it is also possible to make some deformation and improvement, these are implemented all without affecting the present invention
Effect and practical applicability.
