Plate and tube evaporation equipment can be mixed and matched, with multiple evaporator bodies connected to form a complete energy-saving evaporation system.
The final evaporator stage employs forced circulation evaporation and continuous crystallization equipment.
The steam ejector (TVR) in the system contributes to further energy savings. Common configurations include double-effect, triple-effect, quadruple-effect, and quintuple-effect evaporation and crystallization systems.
The material is preheated through a preheater before entering the evaporator.
Inside the evaporator, the material exchanges heat with heating steam and evaporation occurs. The gas-liquid mixture then enters a separator for gas-liquid separation.
The generated secondary steam is compressed by a compressor to increase its pressure and temperature.
The compressed steam is sent back to the evaporator to serve as heating steam, achieving cyclic utilization.
The (TVR+) combined plate-and-tube evaporator-crystallizer is an evaporator type first developed and launched by our company into the market. It features advanced technology, easy operation, high cost-effectiveness in investment and energy saving, low maintenance costs, and significant energy-saving effects.
It can be freely combined into an evaporation-crystallization system that matches the evaporation medium well. For instance, falling film multi-effect, forced circulation multi-effect, and multi-effect evaporation-crystallization systems that combine falling film and forced circulation can all be further enhanced with the addition of steam ejectors to form a more energy-efficient TVR multi-effect system. The TVR steam ejector pump is used to recompress part of the secondary steam as a heat source for subsequent effects.
Using TVR requires a stable supply of steam. The performance of TVR directly affects the steam-saving effect, so it is necessary to use products with guaranteed operational performance. If the quality and performance of the steam ejector pump are poor, the steam-saving effect will not be significant, and it may easily be damaged due to loud noise and significant vibration.
It is suitable for concentration, evaporation, and crystallization in situations where steam prices are relatively low. The pump has a relatively small flow rate and installed power, resulting in low power consumption. The system is equipped with a CIP cleaning system, enabling on-site cleaning. The choice of crystallizer depends on the type of precipitated crystals, with options including the forced circulation crystallizer (FC), Oslo (OSL) crystallizer, and DTB crystallizer.
