Product Description

MVR working principle:

MVR is the abbreviation of Mechanical Vapor recompression
MVR is an energy-saving technology that re-uses the energy of the secondary steam generated by itself, thereby reducing the demand for external energy.
The principle is that the secondary steam evaporated from the evaporator in the evaporation system is transported to the inlet of the MVR compressor through the steam pipe, and the secondary steam is recompressed by the steam compressor (the process of converting electrical energy into heat energy), so that pressure and temperature of the secondary steam increase, ,the enthalpy of the steam increases.
The heated secondary steam is sent to the heat exchanger to heat the liquid, and keep the liquid in a boiling state.
The secondary steam after heat exchange becomes condensed water. In this way, the originally discarded secondary steam is reused, which also achieves the purpose of energy saving.

Advantages of MVR process

1. Low energy consumption
2. Soft product evaporation due to low temperature difference
3. Simple process and easy operation
4. Low operating costs. One-third less than the same multi-effect evaporator
5. Without raw steam, it can still be evaporated by MVR process (electric heating when starting) up)
6. The project occupies less land
7. Stable operation, high automation, suitable for evaporative concentration and evaporative crystallization

Advantages (features) of KDL-MVR compressor

   Low noise, small vibration, stable operation and long lifetime. The reason as follows:

     1.  Except for the castings and standard parts of the steam compressor, all machining is done in the company's workshop. The main equipment of the company is an imported machining center, and the size and precision are well guaranteed. 
    2. The end covers and cylinder on both sides of the compressor are processed by advanced horizontal CNC machining centers with high machining accuracy. The positioning pin holes of the end covers and cylinder are processed by machine tools, ensuring accuracy and avoiding positioning errors with drilling, so that the parallelism of the two shafts (impellers) is better and the operation is more stable.
     3. The impeller and shaft of the steam compressor are an integral structure, which is made of 2205 duplex stainless steel. The concentricity of the impeller and shaft is high. This structure overcomes a series of problems caused by the split of the impeller and shaft. Bearings have longer lifetime
   4.  Compressor bearings use NSK or FAG bearings to make the equipment longer lifetime
  5.  The steam compressor bearing adopts a press-fitting method, which avoids damage to the bearing by beating it with a hammer, and makes the bearing life longer.
  6. The synchronous gear of the steam compressor is a helical gear made of alloy steel. It has less vibration during operation and makes the operation stable.
   7.  Both ends of the steam compressor use double-end mechanical seals to achieve completely leak-free operation. Special gases can be conveyed
   8.   Both ends of the steam compressor use oil tank lubricating oil to lubricate the bearings. It can meet the steam compressor to work under various working conditions. There is an oil mirror on the oil tank to see the oil level in the oil tank, which is easy for maintenance.
   9.   The oil tanks at both ends of the steam compressor are completely separated from the inner cavity of the compressor. The steam and lubricating oil do not affect each other. The special structure ensures that lubricating oil cannot enter the inner cavity of the compressor even when there is a problem with the sealing system of the oil tank. Water vapor cannot enter the oil tank

   10.   The inlet of the compressor uses water spray to solve the generation of supersaturated steam at the outlet. It effectively controls the outlet temperature of the compressor.
   11,  The compressor adopts a top-in and bottom-out structure, which can be up and down, or up and side out. It meets the requirements of different occasions.  It can not only reduce the length of the steam pipeline, but also reduce the pressure loss of the steam in the pipeline.
  12, The steam compressors are equipped with frequency conversion motor, which is convenient for users to adjust the evaporation capacity.

Remark:

1. The flow parameters in the table are the flow when the pressure difference  between the inlet and outlet is 50kpa
2. The evaporation capacity in the table is the evaporation capacity when the secondary steam is 90°C.
