Abstract

The invention relates to a vacuum evaporation concentration device using a composite heat source, which comprises a vacuum evaporator, a hot water tank, a composite heat source and a vapor recovering and circulating device. The vacuum evaporator realizes the boiling and concentration of materials in the evaporator through a liquid heating medium; the hot water tank is connected with the vacuum evaporator and provides the liquid heating medium for the vacuum evaporator; the composite heat source is connected with the hot water tank and provides heat for the liquid heating medium in the hot water tank; and the vapor recovering and circulating device recovers vapor exhausted from the vacuum evaporator and circularly uses the heat of the vapor. In the invention, a composite heat source is adopted, and the structure of the vacuum evaporator is simple and easy to maintain.

Description

technical field [0001] The invention relates to a chemical processing device, in particular to a vacuum evaporation concentration device using a composite heat source. Background technique [0002] In the field of evaporation technology, most of the existing technologies use a single heat source to provide the heat transfer medium for the evaporator. If the heat source fails, it will inevitably affect production. [0003] In addition, using various methods to increase the evaporation liquid film area of ​​the evaporated material is a common means to increase the evaporation rate. Commonly used evaporators include rising film evaporators, falling film evaporators, and scraper evaporators. The heating chamber of the rising film evaporator is composed of many vertical long tubes. The feed liquid is introduced from the bottom of the evaporator after being preheated, boiled and vaporized rapidly in the heating tubes, and the generated steam rises at a high speed in the heating t...
