威海MVR Evaporator

●Commonly used steam compressors mainly include: Roots compressors, axial compressors, centrifugal fans, centrifugal compressors, Roots compressors are mainly used for small flow conditions, axial compressors are used for large flow conditions. The most common steam compressors are mainly centrifugal. Fans  centrifugal compressors.

●Centrifugal fans can be used in applications with low compression ratios up to п=1.25. Like the centrifugal compressor, the gas enters the impeller  the casing in the axial direction as a welded plate structure,  is reinforced with reinforcement when needed. Gear gearboxes are usually  required because the drive system can achieve the required impeller speed.

●The main features of a single-stage centrifugal compressor are: The cantilever impeller  compressor  the compact arrangement of the gearbox, the gearbox  compressor are usually mounted on the same base. The compressor housing is cast  welded. Due to the high tip speed of more than 400 m/small, the impeller is highly affected. It is made of high quality materials such as chrome-nickel steel  titanium alloy.

Working principle

The MVR evaporator is currently the world's leading high-efficiency energy-saving evaporation system. The compressor is used to increase the energy of the secondary steam,  the secondary steam for increasing energy is utilized to recover the latent heat of secondary evaporation.

Specifically, the secondary steam generated by the evaporator is compressed by the adiabatic compression of the compressor to increase the pressure  temperature,  then sent to the heating chamber of the evaporator as heated steam to condense  release heat, so that the latent heat of the steam is recovered. use.

Before entering the evaporator, the cold material absorbs the heat of the condensed water through the heat exchanger to increase the temperature,  also cools the condensate  the finished liquid, further improving the heat utilization rate.

Structure

Heater, gas-liquid separator, steam-water separator, forced circulation pump, liquid conveying pump, vacuum system, drainage system, operating platform, electrical instrument control cabinet  valves, process piping  other systems.

Technical characteristics

●MVR energy-saving evaporator uses a compressor to provide heat source, only a small amount of steam is needed (small amount of raw steam is needed during start-up, almost no steam is needed in normal operation), because 100% recycles the latent heat of secondary steam, thus greatly Reduce energy consumption, greatly reduce operating costs  reduce environmental pollution.

●The material is evaporated under the low temperature system. Compared with the traditional evaporator, the temperature difference is small, no condenser  only a small area of condenser is needed, the material liquid is uniform, the material is  run, the coking is  easy,  the material heat denaturation is minimal.

●For the heat sensitive material, the vacuum pump can be used together, which can be carried out under vacuum close to absolute pressure, so as to achieve low temperature evaporation  at least 50° evaporation.

●The whole set of equipment structure is single, fully automatic operation, continuous operation, safe  reliable.

Application range

It is widely used in the evaporation  concentration of water  solution in lithium, metallurgy, hazardous waste, medicine, food, chemical, light industry  other industries,  can be widely used in wastewater treatment of the above industries.
