Abstract

The invention discloses an evaporation and concentration system, which includes: a mechanical vapor recompression unit for pressurizing steam through an engine-driven water vapor compressor, a multi-effect evaporation and concentration unit with at least one effect heating and evaporation part, and the multi-effect evaporation and concentration The unit is equipped with an exhaust gas waste heat boiler; the exhaust port of the engine of the mechanical steam recompression unit is connected with the exhaust gas waste heat boiler, and the steam generated by the waste gas heat recovery boiler is used for the first steam of the multi-effect evaporation concentration unit. The main heater of the multi-effect evaporation concentration unit in the evaporation part is heated. The present invention is composed of MVR and MEE evaporation units, and the two units are coupled together through an exhaust gas waste heat boiler 12 . The exhaust gas from the engine enters the exhaust gas waste heat boiler to generate steam, and the steam leads to the heater to heat the material. Due to the use of the exhaust waste heat of the engine, there is no need for additional heat energy costs, and the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of relevant technologies, in particular to an evaporation concentration system. Background technique [0002] The evaporative concentration system evaporates the solvent by heating and leaves the solution, and the non-volatile solute is still dissolved in the remaining liquid solvent to realize the separation of the solvent and the solute. Generally, the heat source of evaporative concentration systems is steam, which is usually obtained by burning fossil fuels. The mechanical vapor recompression unit (Mechanical Vapor Recompression, MVR) is different from the traditional multi-effect evaporation concentration unit (Multi-Effect Evaporation, MEE). And temperature, return to the evaporator to heat the material, realize the reuse of steam latent heat, theoretically do not need to use fresh steam, all mechanical vapor recompression units can save energy by 50-90% compared with traditional ev...
