Novel multi-effect water distillation machine

Abstract

The invention relates to the technical field of water distillation machines, in particular to a novel multi-effect water distillation machine. A plurality of baffle plates are arranged in a gas-liquidseparation chamber in the single-effect water distillation machine, wherein the baffle plates are perpendicular to one another to form a stepped baffle plate, the upper end of the stepped baffle plate is connected with a spiral separator, and the lower end of the stepped baffle plate is connected with the top end of a climbing film pipe, so that the gas-liquid separation speed can be increased, and the purity of the steam is ensured; in addition, industrial steam is adopted as a heat source of the first-effect water distiller, pure steam generated by the previous effect is adopted as a heat source of the water distillators except the first effect, and condensate water of the water distillators except the first effect enters a condenser after coming out of the last-effect water distillatorin a communicating mode; wherein the water is used as raw material water for heat exchange and next circulation. Due to the structural design, the purity and temperature of distilled water required for manufacturing are guaranteed, and reasonable utilization of resources is also guaranteed to the maximum extent in a multi-effect connection mode.

Description

technical field [0001] The invention relates to the technical field of distilled water machines, in particular to a novel multi-effect distilled water machine. Background technique [0002] At present, the evaporation methods of multi-effect distilled water machines independently developed or imported in China are falling film type and rising film type. Falling film evaporation is a kind of surface evaporation in which the material liquid flows through the heating surface in the form of a liquid film. Different from ordinary evaporation, during the falling film process, there is no violent boiling of the feed liquid. The falling film water machine adopts the upper part of the water distribution, and the raw material water forms part of the raw material water in the tubes, and part of the raw material water in the tubes, resulting in the raw material water in the tubes. The water distribution is uneven, and the raw material water is affected by gravity during the falling pro...

AI Technical Summary

Problems solved by technology

[0004] The general multi-effect distilled water machine relies on external industrial steam for rising film falling film evaporation treatment, and the distilled water after one rising film falling film evaporation treatment is not pure, and there will be problems of untimely recovery and waste of resources. , Invented a new type of multi-effect distilled water machine for these phenomena
