Energy-saving and environmental-protection method of evaporator

Abstract

The invention discloses an energy-saving and environmental-protection method of an evaporator. The method comprises the following steps: 1, storing and choosing a material temperature working point; and 2, storing and choosing a material heating value, selecting the boosting temperature rising value of a booster fan in the solution material boiling point rising process, and selecting the working temperature point and the boosting temperature rising value of a corresponding material. About 97% or above of heat energy consumed in the evaporative concentration process of the solution material is recycle heat energy, and only about 3% of mechanical energy converted from electric energy and a miniature amount of steam are used as supplementary energy of the heat energy, so the method has an obvious energy saving effect, and also has green and environmentally-friendly effects.

Description

technical field [0001] The invention specifically relates to an energy-saving and environment-friendly method for an evaporator, which belongs to the technical field of energy conservation and environment protection. Background technique [0002] The basic principle of evaporation and concentration technology is to heat the solution material through heat exchange to make the solution material reach the boiling point and separate a part of the solvent from the solution material by vaporization and evaporation to achieve the purpose of increasing the solute ratio in the solution; In the process, in order to separate more solvent from the solution to obtain a solution material with a higher solute ratio, a large amount of heating energy will be consumed. The usual heating energy uses steam as the heating source; with the continuous development of human civilization, energy The consumption of energy is getting bigger and bigger, and the occasions that need to use energy are gett...

[0002] The basic principle of evaporation and concentration technology is to heat the solution material through heat exchange to make the solution material reach the boiling point and separate a part of the solvent from the solution material by vaporization and evaporation to achieve the purpose of increasing the solute ratio in the solution; In the process, in order to separate more solvent from the solution to obtain a solution material with a higher solute ratio, a large amount of heating energy will be consumed. The usual heating energy uses steam as the heating source; with the continuous development of human civilization, energy The consumption of energy is getting bigger and bigger, and the occasions that need to use energy are getting wider and wider, but the total amount of energy in the real human living environment is limited, and the decreasing amount of energy makes the amount of energy that can be used by humans more and more At the same time, a large amount of CO gas will be emitted during the generation of steam energy used, which will cause serious pollution to the human living environment. This requires people to consider how to improve energy utilization efficiency when using energy. and how to use zero-emission renewable energy
