Abstract

The invention discloses an MVR evaporation crystallizer suitable for high salt concentration and crystallization and production process of the MVR evaporation crystallizer, relates to industrial energy-saving equipment, and particularly relates to an evaporation crystallizer suitable for high salt concentration. A first heat exchanger and a second heat exchanger are respectively arranged in a first evaporation chamber and a second evaporation chamber, wherein a steam inlet end of the second evaporation chamber is connected with a steam main pipe; a steam outlet end of the second evaporation chamber is connected with a steam inlet of the first evaporation chamber by a compressor; the steam outlets of the first evaporation chamber and the second evaporation chamber are connected with a condensed water main pipe; a liquid delivery pump is connected between a liquid storage tank and each of the first evaporation chamber and the second evaporation chamber; stirring power devices are arranged on the first evaporation chamber and the second evaporation chamber; stirring devices are arranged in the first evaporation chamber and the second evaporation chamber. In the invention, the evaporation chamber and the heat exchanger of the traditional MVR evaporation crystallizer are changed from a split type to an integrated structure, i.e., the heat exchanger is arranged inside the evaporation chamber, so that the equipment is more compact; a surface of the heat exchanger is exposed in a large space, to facilitate the subsequent crystallization and removal of salt deposits. In a process flow of the scheme, a boiling point of the materials is increased due to precipitation of crystals, so the process flow of a first issue solution is still adopted.

Description

technical field [0001] The invention relates to industrial energy-saving equipment, in particular to an evaporation crystallizer suitable for high salt concentration. Background technique [0002] MVR evaporator is a new type of high-efficiency and energy-saving evaporation equipment mainly used in the pharmaceutical industry. This equipment uses low-temperature and low-pressure steam technology and clean energy as energy to generate steam and separate water from the medium. It is currently the most advanced evaporation technology in the world. , is an upgraded product that replaces the traditional evaporator. [0003] The MVR evaporation crystallizer is a very energy-saving device. Its principle is that the secondary steam generated by the heat exchange evaporation of the evaporator is compressed by the steam compressor to increase the pressure and temperature of the secondary steam, and then returns to the evaporator for heat exchange. The heater is reused as heating ener...
