High quality control Disodium hydrogen phosphate MVR evaporation crystallization
Description
The material enters the top part of the falling-film evaporatoor through the material circular pump and flows in a membranous manner by means of the distribution plate.The primary vapor is the fresh steam heated outside the pipe,boiling the solution to generate the secondary vapor which then is sucked in by the compressor;After pressurization,the secondary vapor has its temperature increased and flows into the heating chamber as a heating source to join the circulating evaporation process.When normally started up,the compressor will suck in the secondary vapor and heat the vapor by means of pressurization.It is in this way that the circular evaporation cycle is then permanently maintained.The moisture evaporated eventually becomes the condensate water and get discharged.No supplement of additional fresh steam is required when the system reach a stable state.
Feature
* Lower operating costs
* Minimum space requirements, single support elevation
* Adaptable to most corrosion resistant materials of construction
* Can be easily instrument controlled
* Simplicity of operation, start-up and shutdown
* Produces a narrow crystal size distribution for easier drying and less caking
* Product size varies only slightly with large changes in production
Principle:
MVR forced circulation crystallization system comprises a vapor compressor,a heat exchanger,a crystallizer,and a forced circulation pump.The system makes use of the externally imposed power(circulating pump)to pump the solution and raw materials in the circulation pipe to the heating chamber.In doing so,the circulation rate is then greatly improved.After the circulating fluid passes through the heat exchanger for heating,it relieves pressure appropriately in the separator and becomes partially evaporated,cooling the liquid to the boiling temperature corresponding to the pressure.The secondary vapor separated from the separator and treated by the compressor is then handled to the heat exchanger for shell side heat exchange,maintaining the evaporating temperature of materials.When the system comes to the stable,no supplement of additional fresh steam is required
Advantages
1, Longer operating cycle:The boiling /evaporating process happens in the separator rather than on the heating surface so that the scaling phenomenon due to crusting and precipitation inside tubes is then minimized.
2, Optimized heat transfer surface:the flow rate inside tubes is determined by the circulating pump.
3, Suitable for easy -to-encrust and high viscosity liquids,acting as a concentrator in the multi-effect evaporation plant.
4, The forced circulation evaporator is operable as a crystallizing evaporator for salt solutions.
