MVR characteristics of plate type evaporator

Principle 1: MVR evaporator

MVR evaporators adopt compressor increase the energy of the secondary steam, and tries to use to improve the energy of secondary steam, heat recovery of secondary steam. Specific for: it will produce the secondary steam evaporator, through the adiabatic compression compressor, the pressure and temperature increase, and as the heating steam heating chamber into the evaporator, condenser heat release, so the latent heat of steam has been recycled.

Principle 2: MVR plate type evaporator

Its principle as shown in the figure below: to be vaporized material is entered into the plate evaporator, preheater after preheating material within the evaporator and the heating steam heat transfer and evaporation, the gas-liquid mixture enters the separator for gas and liquid separation. The secondary steam into the compressor, secondary steam was compressor compressed, as heating steam into the plate evaporator. Heating steam and material after heat exchange, condensed water, heat transfer, the condensed water into the preheater and material preheat material recycling energy. No secondary steam exhaust system, save a lot of energy.

3: the characteristics of the plate evaporator

(1) high heat transfer efficiency: plate corrugated design of thin film with high thermal conductivity as the goal, heat transfer efficiency is very high, generally speaking, the plate evaporator heat transfer coefficient K value from 3000 to 6000 w / ㎡. ℃ range, it is showed that the plate evaporator need only half of the tube shell type evaporator area to 1/4 evaporation can achieve the same effect.

(2) the cover an area of an area small, easy to maintain, the structure of the plate evaporator is very compact, the evaporation under the same conditions, the occupied space is only 1/3 of the tubular falling film evaporator to a quarter of its height is only about 1/10 of the tubular falling film evaporator, only need to loosen the clamping screw and maintenance, can be entirely within the confines of the original space come into contact with in the surface of the hot plate, and easy to tear open outfit.

(3) equipment heat exchange area of adjustable: because of the heat exchange plate is easy to remove by adjusting the number of heat transfer plate or change process can be the most appropriate heat transfer effect and capacity, middle frame, as long as the use of evaporator heat transfer plate parts have a variety of unique function. So it provides users with can change at any time and change rate of heat transfer coefficient K value or the possibility of adding new features.

(4) small heat loss, because of the compact structure and small volume, surface area of the evaporator is small (compared with tubular falling film evaporator), and heat loss is very small, usually no longer need to heat preservation equipment.

(5) : less pressure loss in the same conditions of heat transfer coefficient, plate evaporator through reasonable selection of the velocity, pressure loss can be controlled in the range of the 1/3 of tube evaporator.

(6) the use of safe and reliable: in the plate between the 2 seals, sealing device design at the same time also is equipped with the signal, once the leak, it can be ruled out evaporator outside, to prevent the steam and material mixed already, and have played an important role in the security alarm.
