Description
Technical field
The utility model is related to a kind of evaporators, are related specifically to a kind of rotary evaporator, also relate to containing rotation
The low-temperature evaporation condensing crystallizing equipment of formula evaporator.
Background technology
Existing evaporation process technology needs to run under higher temperature condition due to generally making water be in fluidized state,
Or certain vacuum degree is kept to reduce the boiling point of water, therefore on the one hand need to consume a large amount of steam or electric power, another aspect height contains
Salt waste water often contains a large amount of corrosive contaminants matter, and hot conditions increase equipment corrosion risk, meanwhile, violent evaporation
Process is but also scale problems are more serious.In order to ensure the continuous and steady operation of equipment, more expensive metal must be just selected
Material, while stringenter softening is carried out to waste water and is pre-processed so that vapo(u)rization system cost of investment and operating cost occupy height not
Under.
The multiple-effect evaporation technology being widely used at present（Multiple EffectDistillation, are abbreviated as MED）And steaming
Vapour recompresses evaporation process technology（Mechanical VaporRecompression, are abbreviated as MVR）.With evaporation process
It carries out, liquid waste concentration with high salt gradually rises, when beginning with crystal precipitation after saturation, it may occur that block pipeline, Incrustation of pipe etc. one
Concentrating spent liquor is discharged before this for series of problems, most of selection, carries out subsequent processing.Concentrate is handled in evaporation field
The problem of must facing, there is special crystallizer at present for the crystallization of salt, but usual to the mixture of what organic matter and salt
Situation is more complicated, and general condensing crystallizing and centrifugal dehydration are difficult to meet the requirements or cause burn into dirt stifled etc..
The evaporation rate of liquid in addition to other than by itself impact on physical properties, mainly also by fluid temperature, liquid with
The influences such as the contact area of gas phase and the air velocity of liquid surface.Accelerating liquid evaporation has 3 kinds of methods：1. improving liquid temperature
Degree, 2. expand liquid surface area, and 3. accelerate liquid surface air circulation.The steam that the evaporation of liquid generates can absorb largely

Filler is generally corrugated plate packing.
Ideally, the contact area of the specific surface area of filler more flood and air is also bigger, the sky around filler
Gas is easier to reach saturation state, but if saturated vapor cannot remove in time, the evaporation rate of liquid is still very low.Cause
This, while humid air can reach saturation in time in evaporator, makes the air velocity of liquid surface add using wind turbine 4
Soon, the evaporation rate of liquid is also accelerated therewith.The high hot-air of water capacity to the cold object contact will dew condensation, damp-heat air
After cooled, become cold dry air.Large area heat exchanger 7 made of current multiple-effect evaporation and MVR generally use metals is used
In to the heating of material and the condensation of damp-heat air, even if not considering the factor of corrosion and scaling, using metallic recuperator 7 come between
Heat exchange is connect, is always restricted by heat exchange efficiency, to influence heating and condensation efficiency.
It is not high for some viscosityes, salt content is unlikely to the sewage of crystallization in water, when existing evaporation technique can be square
Just it runs, but if Organic substance in water is more and is concentrated to a certain concentration, forms the strong brine of high viscosity, at this time evaporative condenser
It is difficult to go on, evaporator, heat exchanger 7, line clogging is easily caused if it cannot rationally handle.
