Description

    MVR evaporator, is an evaporation and concentration equipment with mechanical vapor recompression (thereinafter abbreviated MVR) , recycling the secondary steam completely with compression.

MAIN PRINCIPLE

    The MVR evaporator makes use of the secondary steam produced during evaporation. After compression by the compressor, the pressure, temperature and the enthalpy of the secondary steam is increased, and it is sent to the heating chamber of the evaporator and acts as heating medium to maintain the feed liquid boiling. Thus, the waste steam is fully utilized, the thermal efficiency is improved, the demand of external heating and cooling is reduced, the energy consumption and pollution are reduced.

SCOPE OF APPLICATION

    The MVR evaporator is suitable for concentration and crystallization of various material, especially for material of small boiling point elevation and diluted material which are easy to be evaporated.

MAIN FEATURE

    1). MVR Evaporator is the international advanced evaporator, a tiny amount of live steam is required (the tiny amount of steam is required for startup, and then almost none is needed for normal operation), reduces the operation consumption and the environmental pollution.

    2). Compared to the traditional evaporator, the temperature difference is smaller because the heat source is provided by the compressor, thus the evaporation is gentler, which improves the product quality greatly and reduces the scale.

    3). No need of condenser or a small condenser is workable, the structure and the process flow are simple, easy to realize full automation, safe and reliable.

    4). There is built-in CIP cleaning pipeline, is able to realize on-site cleaning, which is easy to operate, and free of blind spot.

    5). The material is evaporated under condition of low temperature (evaporation temperature @ 50℃～100℃) and free of foam. The material is uniform and not easy to coking or denaturation.

    6). The installation space of MVR evaporator is about two times that of the traditional multiple-effect evaporator, the investment cost is higher too, and operation cost is much lower.

    7). In order to avoid failure of MVR caused by misoperation, automatic operation system is necessary for protecting safe operation of equipment.

SYSTEM COMPONENT

    A MVR evaporator is composed of heaters, separator (crystallizer), MVR, vacuum pump, material circulating pumps, operation platform, instrumentation and control cabinet, and pipeline and fittings.   

TREATMENT CAPACITY

    Customized according to demands, 0.1~200.0ton/hour.
