A, oslo oslo crystallizer crystallizer Overview Oslo crystallizer can also be called as early as the 20th century, it was suggested that this crystallization techniques, because the particle size of the mold to make the solution reached supersaturation and runtime it generates, the growth of crystal nuclei have this good effect. Two, oslo mold our principles now applied OSLO crystallizer www.wzgoody.com can be divided into two categories: 1, evaporative OSLO OSLO crystallizer principle evaporative crystallizer is: the application of an external heater is equipped with a crystallizer inner loop material heated to re-enter the vacuum flash chamber steamed reached saturation, and then enter a suspended bed by a vertical pipe to the crystal growth, due to the special structure of the Oslo crystallizer, the larger particles are first contacted saturation solution is the first increase, followed by a small volume of the solution; 2, cooling type crystallizer cooled OSLO OSLO OSLO crystallizer and the evaporative crystallizer similar principles, but also through external cooler saturated material was cooled reached saturation then enter a suspended bed by a vertical pipe crystal growth, due to the special structure OSLO crystallizer, larger particles faster contact supersaturated solution it will grow faster. So our OSLO crystallizer produced crystals have a large crystal size, narrow particle size distribution and uniform, large production capacity. And has a continuous operation, low labor intensity. Third, the industry-wide applications oslo crystallizer and crystallization of oslo main applications now are: salt, metallurgy, MSG, aquatic products processing, manufacturing, and other soft water. OSLO salt industry is commonly used in a typical mold. Its characteristics are the solution flows out from the upper mold into the forced circulation pump, after the adoption of the solution can generate through the device saturation entering the mold center downcomer, gradually formed crystals were grown up after sinking to the bottom of the mold, remove for the product. In the cycle of the material, the use of clear liquor circulation, crystals do not participate in the cycle and therefore can not easily be broken, crystallized from crystallizer central settlement restriction is not removed, the crystal growth environment is good, so a large crystal grain size, up to 6-20 mesh, i.e., 3mm large. No mixing the mold. Four, oslo crystallizer and crystallization process required during operation of the mold, the main factors affecting the crystallizer http://www.wzgoody.com/Product/jjq/asljj.html crystallization solution is reached over saturation, Application of such a crystalline salt production, water or other material was circulated to over-heating chamber outlet saturation generated by the circulation pipe boiling zone, feed-liquid saturation degree with boiling rapidly. But oversaturated too does not work, because that will make the nuclei into a rate rise too fast, so that the crystal contains impurities affect crystal quality. Fifth, the structure type and design features oslo oslo mold structure type is shown in the mold of its characteristics are: ① the upper part of the expanded fertility crystal section can settle the salt crystal, is not involved in the cycle, reduce the secondary nucleation opportunities; ② fertility crystallizer bottom of circular arc, which improves material flow state within the sterile liquid crystal device to warrant the formation of dead zone; ③ design also took into account the fertile grain per reservation within brush pot feed liquid tank brush way, both only brush the heating chamber, so as to avoid the loss of fertile grain tank large grain of salt, and resume production of qualified brush canister of salt time can be shortened. ④ circulating pump motor with adjustable motor by adjusting the motor speed to regulate the circulation pump flow rate, thereby regulating the circulation supernatant salt crystal grain size and the number of exhaust systems; ⑤ feed liquid feed from the bottom of the evaporation chamber, the upper central tube material, reducing the temperature difference between the short-circuit losses, but the material was in the process of rising evaporation chamber and a particle dissolution process, solid-liquid unsaturated into saturated can reduce the number of fine crystals to ensure granularity salt; ⑥ design Fertility crystal cone section on setting up the mother liquor discharge pipe, it can drain the tank liquor control Na2 SO4 content, salt crystals can also be a number of fine discharge systems, in order to maintain the tank nuclei relatively stable, favorable salt increases;
