Introduction
MVR evaporator is a new type of high-efficiency and energy-saving evaporation equipment mainly used in the pharmaceutical industry. The equipment uses low-temperature and low-pressure steaming technology and clean energy to generate steam as energy to separate the water in the medium. It is an internationally advanced evaporation technology. It is an upgraded product that replaces the traditional evaporator.
Ammonium sulfate is a relatively common chemical wastewater component. Its characteristics are high solubility and high degree of supersaturation. Equipment and pipelines are easy to scar, scale, and block. After blockage, the solid is hard and difficult to clean, which causes many inconveniences to the evaporation and crystallization process. Therefore, in the design of the MVR evaporative crystallization system of ammonium sulfate, it is necessary to focus on the problem of ammonium sulfate crystallization blockage, and the anti-blocking measures such as purge and replacement should be considered in the liquid level measurement part, discharge port, pipeline, pump, etc. of the equipment.
Technical characteristics
(1) Low energy consumption and low operating costs;
(2) Small footprint;
(3) Few supporting facilities for public works and low total project investment.
(4) Smooth operation and high degree of automation;
(5) No need for primary steam;
(6) Due to the common single effect, the product staying time is short
(7) The process is simple, the practicability is strong, and the partial load operation characteristic is excellent
(8) The operating cost is low, and it can evaporate below 40°C without freezing equipment, which is especially suitable for heat-sensitive materials.
The MVR evaporation equipment is compact, has a small footprint and requires a small space. The cooling system can be omitted. For existing factories that need to expand the evaporation equipment to supply steam, have insufficient water supply capacity and insufficient space, especially the occasions where freezing water condensation is required for low-temperature evaporation, it can save investment and achieve better energy-saving effects.
