MVR (mechanical vapor recompression) evaporator structure with integral gas-liquid separation structure

Abstract

The invention relates to a MVR (mechanical vapor recompression) evaporator structure with an integral gas-liquid separation structure. The MVR evaporator structure comprises a casing (1), wherein an evaporation pipe beam (2) is arranged inside the casing (1); a secondary evaporation pipe (3) is arranged in the central axis position in the casing (1). The MVR evaporator structure is characterized in that a gas-liquid separator (6) is arranged at the bottom of the casing (1); the gas-liquid separator (6) and the bottom of the casing (1) are detachably connected; an inner cavity defined by the casing (1) and the gas-liquid separator (6) is a sealed cavity. The MVR evaporator structure has the advantages that the occupied ground area of equipment is effectively reduced; meanwhile, foam generated by material liquid can be eliminated.

Description

technical field [0001] The invention relates to an MVR evaporation system, in particular to an MVR evaporator structure with an integrated gas-liquid separation structure. It belongs to the technical field of evaporators. Background technique [0002] With the development of industrial technology, mechanical vapor recompression technology (MVR), also known as direct heat pump technology, usually uses electricity as energy, and uses a steam compressor to increase the secondary steam pressure and temperature and return it to the evaporator for reuse. In the field of industrial wastewater, including chemical wastewater, pharmaceutical wastewater, high-salt wastewater, dye wastewater, electroplating wastewater, etc.; in the field of food industry, including evaporation and concentration of fruit juice, milk, and sucrose; in the field of pharmaceuticals, including concentration of traditional Chinese medicine , vitamins, and amino acids are evaporated and concentrated; in the ch...

AI Technical Summary

Problems solved by technology

[0003] 1. The gas-liquid separator is outside the main body of the equipment, and the equipment occupies an enlarged area;

[0004] 2. There is no defoaming device during separation, and the material liquid is directly flowing down, which is easy to generate foam;

[0005] 3. The foam is easy to be strung together with the gas into the vacuum pipeline. In extreme cases, it may reach the steam compressor, causing damage to the steam compressor
