The working principle and characteristics of quality OSLO evaporation crystallizer
The quality OSLO evaporation crystallizer is composed of OSLO evaporator, heat exchanger and forced circulation pump. Today, I will briefly share with you the working principle and characteristics of the evaporative crystallizer. Interested friends will follow the editor to take a look.
Introduction to the working principle of quality OSLO evaporation crystallizer
The quality OSLO evaporation crystallizer material is heated by the steam outside the heat exchange tube in the heat exchange tube of the heat exchanger and the temperature rises. Under the action of the circulating pump, the material rises to the evaporative crystallizer, and the material evaporates in the OSLO crystallizer due to the drop of the static pressure of the material.
Evaporation produces secondary steam that overflows from the material, and the material is concentrated to produce supersaturation. The supersaturated solution descends in the central tube of the quality OSLO evaporation crystallizer and fully contacts the small crystals in the solution to further grow the crystals. Column elutriation The large crystals are deposited under the elutriation column and transported to the thickener with a slurry pump. Smaller crystals continue to grow in the OSLO crystallizer.
The clarified liquid is transported to the heat exchanger by the forced circulation pump to continue heating, and the material is continuously evaporated and concentrated or concentrated and crystallized in this way. The secondary steam in the quality OSLO evaporation crystallizer is purified by the separation and de-foaming device at the upper part of the separator and then sent to the compressor. Realize thermal energy circulation and continuous evaporation.
Introduction to the features of quality OSLO evaporation crystallizer
The main feature of the quality OSLO evaporation crystallizer is that the supersaturation area and the crystal growth area are set at two places in the crystallizer, respectively. The circulating mother liquor stream of the crystal is sulfurized and suspended, which provides good conditions for the growth of the crystal. The crystal grain size is large, the grain size is uniform, the equipment volume is large, and the cost is high, and it is suitable for the production of materials that require a large crystal grain size. After the feed liquid enters the system, it is sent to the evaporator by the circulating pump. After being heated and evaporated, it enters the evaporation chamber. The solution after the separated secondary steam is sent directly to the bottom of the crystallizer growth section from the central descending pipe, and then flows upward through the crystallization flow. The chemical bed and supersaturation disappear, and the grains in the crystal bed grow. When the grains grow to the required size, they are discharged from the product outlet. The secondary steam separated by the evaporation chamber is heated by the compressor and sent to the heating chamber of the evaporator as heating steam.
The above is the "introduction to the working principle and characteristics of quality OSLO evaporation crystallizer" that I shared with you today. I hope today's sharing can help you to further understand the relevant content of the evaporator, and I hope it can help you in need.
