Abstract

The invention relates to the technical field of evaporation equipment, and provides a skid-mounted MVR evaporation device, including a raw material supply system, an evaporation circulation system, a vacuum system, and a waste heat recovery system. The materials in the raw material tank enter the preheater, and enter the evaporation after preheating. The evaporator is connected to a steam generator, and the steam generator provides a heat source for the evaporator. The material absorbs heat in the evaporator and enters the separator. The material is concentrated in the separator and discharged after reaching the set concentration. The concentrated material flows back into the evaporator, and the steam in the separator enters the steam filter and then enters the compressor. The compressor heats and pressurizes the steam and returns it to the evaporator. The heat source pipeline of the evaporator is connected to a vacuum pump, and the vacuum pump sucks the heat source. The vacuum tail gas in the pipeline, the vacuum tail gas enters the raw material tank for heat exchange and then flows into the water tank. The invention provides a skid-mounted MVR evaporation device which is miniaturized, modularized, skid-mounted, heat is fully utilized, and fouling is prevented.

Description

technical field [0001] The invention relates to the technical field of evaporation equipment, in particular to a skid-mounted MVR evaporation device. Background technique [0002] MVR is the abbreviation of mechanical vapor recompression technology. MVR is an energy-saving technology that reuses the energy of the secondary steam generated by itself, thereby reducing the demand for external energy. MVR technology has been successfully used in the fields of chemical industry, food, papermaking, medicine, seawater desalination and sewage treatment. [0003] The research of MVR technology mainly includes three parts: overall system equipment, steam compressor and evaporator. Among the new energy-saving and high-concentration wastewater (liquid) technologies, MVR evaporation technology is the most advanced evaporation technology at home and abroad. It has the advantages of low energy consumption and environmental protection. This technology fully recovers the waste heat of the s...
