The controlled amount of seed crystals in the circulating concentrated salt wastewater in the evaporator is an important monitoring indicator to prevent the precipitation of the same crystal form and low solubility of salts attached to the heat exchange tube (or surface) during the crystallization process. Its control boundary is narrow, it is easy to vibrate, and the monitoring and analysis results are lagging behind. Once the seed amount is not quickly found for adjustment, scaling may have occurred.

Wastewater evaporators often use multi-effect evaporation processes to achieve low energy consumption. The multi-effect evaporation crystallization process is used to treat industrial sewage or wastewater, so that the water after evaporation can meet the national discharge standard. At the same time, according to the characteristics of high concentration of salty wastewater, forced circulation evaporators are generally used for wastewater evaporators, which will not cause pipe blocking in the heating room, which will affect production. When the concentration is low, a falling film evaporator and a forced circulation evaporator can also be combined.

The advantage of the process of high-salt wastewater evaporator is that when the solution concentration increases, the temperature of the solution also increases, so the difference in the dryness of the effects is not too large, and the heat transfer coefficient can be improved. In addition to the processes commonly used in equipment production, according to the production situation, there are some other process arrangements for high-salt wastewater evaporators.

Horizontal intelligent crystallizer is suitable for materials with high viscosity and large amount of cooling, such as glucose, xylitol, xylose, nitrate, methyl phosphite, osmium, osmium, etc.

Before starting the MVR evaporator, all the equipment needs to be checked. The areas to be checked are electricity, water, pump units, pipelines, etc. These components must be kept closed, and the MVR evaporator must ensure that The raw material standard required by the evaporation system daily must be handled well in this step. When using the MVR evaporator, the operators must understand all the safe operating procedures. When using the MVR evaporator, the operators need to train them to let employees know how to operate it properly. When it comes to products, you need to adjust the performance parameters and working steps of mvr evaporators according to different products. Because each product has different requirements for the machine, it is necessary to properly adjust the parameters of the equipment so that each component All of them can work well together, don't "make a big deal" and make each device work better together. When the mvr evaporator is in use, there must be a clear arrangement for the workload of the machine. The premise of the arrangement is to understand how much the workload of the machine is. If the workload of the machine exceeds the workload of the machine, It may cause damage to the machine, so be careful when scheduling work.

Membrane mechanical vapor recompression cycle evaporation technology: Based on the MVR evaporation technology, a falling film evaporation is used, and a wastewater circulation pump is set under the evaporator. When the wastewater does not reach the required concentration through the evaporator, it can be recycled. Pump to the top of the evaporator and circulate again until the desired concentration is reached.

The material is evaporated and concentrated through the equipment, vacuumized and low-temperature evaporated and concentrated, coupled with continuous feed and discharge, the heating and evaporation time is short, and it is suitable for the heat-sensitive evaporation and concentration of food sauce materials.

MVR evaporator is a new type of high-efficiency energy-saving evaporation equipment mainly used in the pharmaceutical industry. It is an internationally advanced evaporation technology and an upgrade product that replaces the traditional evaporator.
