Multiple-effect Evaporation System
Description :
Evaporation is the process used to concentrate a solution by removing the solvent(mainly water) in a purified form by the application of heat.
Evaporation is the unit operation by which solvent is evaporated from the solution by boiling the liquid in suitable vessel and withdrawing the vapor,leaving a concentrated liquid residue.
Features
1. It can be also used together with the coercive circulation
evaporator and crystallizer to deal with the concentration and
product crystallization of high viscous and easy scaled material.
2. It is characterized by high efficiency of heat conduction, low
power consumption etc.
3. It can widely use the waster heat (such as the drier's hot air
and flue gas), the remaining heat (of condensing water, process
water and flash steam) to form a waste heat evaporation machine
unit.
Structure
Multiple-effect falling film evaporator consists of (first-effect, second-effect, third-effect)separators and evaporators and pre-heaters,condenser and vacuum pump, feeding pump,circulation pump, discharge pump, condensed water pump, pipeline and fittings, etc. It is equipped with vacuum gauge, thermometer,pressure gauge,and so on.
Multiple Effect Evaporators are widely used in the following areas as per the requirement.
Effluent Treatment: Industries like Chemical, Pharmaceutical, Textile, Dyeing, Breweries, Automobiles, Milk, Food industries etc, generates process effluents which are harmful to the environment. These effluents generally consist of water in huge amount and waste(contaminants). By evaporating the water from the effluent using MEE system results in the recycling of water.
Desalination: Reject of RO (Reverse Osmosis) have a huge amount of water. With MEE the water can be recycled.
Chemical Industry/ Pharma Industry: For the production of product the desired concentration is required or desired material need to be separated. Using MEE system desired concentration is achieved.
Milk Industry: Milk can be concentrated in the MEE system.
Sugar Industry: Sugar cane juice can be concentrated with MEE system.
Food industries: Tomato juice concentration, Sausages, Fruit juice concentration can be done in MEE system.
Advantages: Evaporation can be achieved with low consumption of heat source.
| Performance Comparison for Different Evaporator | ||||
| Item | Single effect evaporator | multi-effect evaporator | TVR evaporator | MVR evaporator |
| Energy consumption | energy consumption is much higher than others, 1ton water will consume 1Ton steam in theory | comparatively energy conservation | Base on traditional multi-effect evaporator, one more effect added, but higher pressure steam driven needed | The most energy saving technology for evaporator, but 10-40kwh power consumption |
| Floor space | Small | large | large | small |
| Energy sources | steam & power, need steam pipe network and boiler | steam & power, need steam pipe network and boiler | steam & power, need steam pipe network and boiler, need high pressure steam. | electricity, don't need pipe network, all the close-loop circulation system |
| Automaticity | Semi automatic | Full automatic operation, continuous evaporation | Full automatic operation, continuous evaporation | Full automatic operation, continuous evaporation |
