Description
Technical field
This utility model relates to sewage disposal, particularly to a kind of steam forced circulation and the vaporizer of vacuum energy-saving.
Background technology
The MVR vaporizer typically now introduced from Germany based on the eighties for the vaporizer technology of sewage disposal, i.e.
Mechanical steam recompression technology.
But MVR vaporizer is greatly limited and obstacle on sewage disposal technology.MVR vaporizer is owing to using lobe pump
Or centrifugal fan carries out the secondary mechanical compression of stock solution steam.It is thus impossible to be used directly to process heavily contaminated, poisonous and harmful,
The sewage of highly corrosive, can only process through precipitating, neutralizing, after the traditional wastewater process means such as filtration pH value in the neutrality of 6-9
Water quality, the stock solution steam that could be formed after evaporating stock solution carries out mechanical compress increases hot break, and the indirect steam of formation is as warm
Heat exchanger tube in vaporizer is heated by source, and indirect steam is cooled into the distillation with certain chemical composition after heat exchange
The crystallized process of concentrated solution that water produces after outside drain, evaporation, forms the calcium ions and magnesium ions containing raw sewage chemical composition
The method of solid matter otherwise processed.This method can cause stock solution quantity of steam to arrange because of the distilled water being condensed into chemical substance
Putting, cause the quantity of steam provided to mechanical compress pump to gradually reduce, vapor (steam) temperature produces state fluctuated therewith, if desired
The fresh steam of outsourcing to be increased supplements the deficiency of quantity of steam to ensure the working condition of vaporizer.Therefore the structure of MVR vaporizer
It is to guarantee to provide a constant vapour amount and the steam source of steady temperature in vaporizer, causes the weight that heat exchange efficiency is the highest
Want reason.
