Supply MVR falling film evaporator, mvr evaporator, falling film evaporator manufacturer

A, MVR falling film evaporator saving reasons MVR falling film evaporator is compressed by the compression device will enhance efficiency through a secondary steam heater energy to this secondary vapor compression after the exploit, which was the second steam Internal latent heat is recovered. Detailed Description namely: secondary steam evaporator www.wzgoody.com generated by the adiabatic compression of the compressor, its pressure, after the temperature was raised, and then fed to the evaporator as the heating steam heating chamber, condensation heat, Thus the latent heat of steam has been recycled. Two, MVR falling film evaporator principle MVR falling film evaporation process principle is to require the evaporation of material from the feed pump into the falling film evaporator http://www.wzgoody.com/Product/zfq/mvrjm.html top through the evaporator heater tube, the membrane of cloth uniformly converted into a film of the material fed into the heat transfer tubes, after the material is evaporated with gravity flow lumen when heated by steam of the tube, reaches the evaporation temperature , materials along with the top down and the secondary steam from the inner tube in the form of a thin film of a stream and evaporated. Furthermore, after the second steam via steam compressed by the compressor, it can be re-fed into the heating chamber shell falling film as heated vapor (compressed energy increases). Falling film heat chamber shell has sections that can guide the secondary steam, condensate and gas condensate to not be processed. In the course of the heat through the wall itself rumored to evaporate from the inner tube material, through the heat exchanger secondary steam condenses into water from a falling film evaporator outside. Third, falling film evaporation system features: 1) falling-film evaporator feed liquid is added from the top of the evaporator, under gravity into a film along the wall fell, and is evaporated by heating the tube through the process concentrated, concentrated liquid obtained at the bottom. Falling film evaporator can be evaporated higher concentration, high viscosity (e.g., within 0.05 ~ 0.45Ns / m2 range) materials. 2) Because the film-like material was flowing in a falling film evaporator, so increasing the heat transfer coefficient. Small 3) liquid holdup, falling film evaporator can be supplied according to the energy, changes in the degree of vacuum, feeding quantity, concentration, etc. and take a quick operational. 4) As the process fluid flow under gravity only, rather than temperature differential to drive, you can use the low temperature difference evaporated. 5) material by heating the tube a short time, it is not likely to cause material deterioration, etc., suitable for processing milk and other heat-sensitive materials. 6) due to falling film evaporator feed liquid into a film in the heating tube evaporation, so the formation of vapor-liquid separation, and the effect on the bottom of the body, most of the feed solution will be pulled out, only a small part of the stock solution with all two secondary vapor into the separator strengthen separation, so the whole process feed liquid will not cause much impact, effectively avoid the formation of bubbles, so the falling film evaporator is also very suitable for evaporation and concentration foaming material.
