VACUUM MECHANICAL VAPOR COMPRESSION EVAPORATORS TECHNOLOGY

DESCRIPTION:

The AQUANET Evaporation System, developed by SPL, SL is designed to solve the problem in-situ caused by the waste generated by wastewater from production processes, especially those from degreasing or emulsions exhausted.

The evaporation of this industrial water is a good alternative, collecting and purifying in the same process in which they occur. Today it is possible in almost all cases the process of reintroducing into the distillate by a water treatment system. For all this, we see that a water treatment site has numerous advantages: a saving in water consumption, such as reduced pollutant discharge, with corresponding savings.

The equipment is designed to work continuously (24 hours/7 days) as core of recovery of all waste water, or with another machine that you want to be kept free of debris during their working time.

The concentrates varies according to their percentage in the original fluid. For degreasing water containing between 1-3 percent oil, concentrates vary from 2.5 to 5%.

AQUANET evaporator is designed as a vacuum evaporator unique technology that incorporates the technology of mechanical vapor compression, with applications ranging from desalination of sea water to the space industry. Evaporation by mechanical vapor compression trying to recover the latent heat of condensation of the distillate as a source of heating of the liquid to evaporate. To this end, the temperature of steam generated in the evaporation, is increased by compression of the steam itself. Thus, the superheated steam can be recycled through a heat exchanger evaporator itself achieving a dual objective: Saving energy for evaporation and to prevent the cooling medium for the condensation (cooling tower, etc.).

Energy consumption is 50-60 Kwh. per 1000 litres of distilled water. This consumption is to assume about 3% of the external costs of waste management. The amortization is usually made in less than eight months.

 
The vacuum evaporation is to reduce pressure inside the boiler below the atmospheric pressure. This reduces the boiling temperature of the liquid to evaporate, which reduces the amount of heat to add / remove in the process of boiling and condensation, as well as other technical advantages of being able to distil liquids with high boiling point, avoid decomposition temperature sensitive substances, etc.
