Evaporator ME3

The ME3 vacuum evaporator is a plant integrated by three evaporators arranged in series called “effects”. Each one of them contains in the lower part and interchange in the form of a coil, through which water vapor circulates, and that is in charge of heating the treated dissolution that we want to evaporate.

The system works in a vacuum guarantying the minimum energy consumption.

For the system to work is necessary that an external boiler provides water vapor (or hot water) to the first effect. The vapor generated in this first effect (first boiler) is channeled to the coil in the second effect, the same way happens in the third effect.

This way, we are taking advantage of the energy produce evaporating great amounts of waste at a very low energy cost.

The distance between the level of effluent to be treated and the condensates recollection tray, guarantee the absence of drag and in consequence a high pure distilled.

Power circuit

The ME3 series evaporators function with vapor water that comes from an external boiler (or hot water) in order to boil the waste, and cold water ( from tower or refrigerator) to recondense the distill.

The necessary energy for the distillation its only provide to the first effect of the plant.

The other effects are power with the distilled product of the previous effect, with the aim of reducing the energy consumption.

Vacuum circuit

In order to achieve the necessary vacuum inside the boiler a system of a vacuum liquid ring pump and an ejector is use.

Adjusting the right refrigeration temperature of the liquid ring of the vacuum pump will guarantee having different degrees of vacuum indispensable for the whole plant to work correctly.

Distill circuit

The concentrate discharge is made in an independent way.

Each effect has attach a deposit to accumulate the independent distill; each deposit has a centrifugation pump directed by a team of levels that constantly discharge the produced distill.  

Concentrate Circuit

The concentrated product is discharged though a special pump (for high concentrations 1.200-1.300 g/l)that allows to discharged and recirculate the concentrate for a better uniformity of the waste, less formation of incrustations and the increase of the exchange heat coefficient.

Each effect is equipped with an independent discharged pump.

Automatization, alarms and control.

C&G evaporators can work 24/7 without necessary control, thanks to the management of the PLC.

The easy and intuitive configuration of the software allows and easier reading and an immediate configuration of the working parameters.

The use of a screen (optional in very model) guarantees an efficient and quick global control of the machine.

Frigorific Circuit

The need to reach a constant and inferior temperature inside the vacuum barrel of the last effect make us installed a little circuit of industrial cold.
