MVR evaporator, short for mechanical vapor recompression. MVR is a technology that reuses the energy of its own secondary steam, thereby reducing the need for external energy. The secondary steam is compressed by the compressor, the pressure and temperature can be increased, and the enthalpy increases accordingly. It is sent to the heating chamber left for evaporation as the heating steam, namely the steam, so that the material liquid can maintain the evaporation state, and the heating steam itself will transfer the heat to the material and become condensed into water. In this way, the steam originally to be discarded is fully utilized, the latent heat is recovered, and the thermal efficiency is improved.The price is negotiable

1.The evaporation operation of several evaporators running in series makes the steam heat energy be used many times, so as to improve the utilization rate of heat energy, which is mostly used for the treatment of aqueous solution. In the process of three-effect evaporation operation, the first evaporator (called the first effect) takes the raw steam as the heating steam, and the other two (called the second effect and the third effect) takes the secondary steam of the previous effect as the heating steam, which can greatly reduce the amount of raw steam. 2.process - CharacteristicsThe system is equipped with an efficient foam removal device to avoid material foam entrainment leading to material run-out.Adopt level automatic control system, automatic feed, automatic discharge of condensed water.Heater, preheater and condenser tube plate adopt integral tube plate to extend the service life of the equipment.Discharge using separation device, increase the discharge crystal content, after separation to obtain most of the crystal, mother liquid reflux is little, need to consume less heat energy, special energy saving.Forced circulation evaporation, which has the advantages of high heat transfer coefficient, evaporation strength, prevent wall and tube blocking, especially suitable for the evaporation process of crystal materials.The separator adopts DTB mode to effectively separate the turbid liquid and avoid the crystal entering the heat exchange tube.The pump self-circulating system is adopted to keep the crystal and mother liquid circulating at all times and avoid crystal deposition and pipe blocking. 3.caseProject Name: Guangzhou XXXX Co., LTDAddress: GuangzhouProcessing scale: 6T/hProcess flow:Physicochemical + biochemical +MBR system + roll RO+DTRO+ multi-effect evaporationInlet water quality: COD≤20mg/L; Conductivity ≤1900us/cmEffluent standard: "Industrial Water Quality of Municipal Sewage Recycling" GBT19923-2005 The price is negotiable

1.) Principles of DTROThis technology is specially developed for the treatment of concentrated wastewater. Its membrane component structure is completely different from that of the traditional coil membrane. The flow channel of the stock liquid: The saucer-tube membrane assembly has a patented flow channel design form, using an open flow channel, the material liquid through the entrance into the pressure vessel, flow from the channel between the guide plate and the shell to the other end of the assembly, at the other end of the flange, the material liquid through 8 channels into the guide plate, the treated liquid with the shortest distance quickly flow through the filter membrane, and then 180º reverse to the other membrane surface. Then it flows into the next guide plate from the notch in the center of the guide plate, so as to form a double "S" shaped route from the circumference of the guide plate to the center of the circle, and then to the circumference, and then to the center of the circle on the membrane surface. The concentrated liquid finally flows out from the flange of the feed end 2.) Process - Characteristics1. Strong process stability, simple maintenance, low energy consumption.2.
