Quickly understand the operation principle and maintenance method of the scraper film evaporator _ Material
Original title: Quickly understand the operation principle and maintenance method of scraper film evaporator Wuxi Huabang Intelligent Equipment Co., Ltd. is a professional manufacturer of stainless steel reactors, spiral plate heat exchangers, tube condensers and scraper evaporators, among which the scraper film evaporator is also a high-efficiency conductive concentration equipment in Huabang products, which uses high-speed rotation to distribute liquid into a uniform film for evaporation or distillation. But also can carry out unit operations such as deodorization, defoaming reaction, heating,thin film distillation, cooling and the like, is particularly suitable for evaporating materials with high heat sensitivity and high viscosity, and has the advantages of compact equipment and continuous shutdown operation. Due to the unique structure of the scraped film evaporator,nutsche filter dryer, the film scraper has a pumping function, so that the retention time of the material in the evaporator is very short; on the other hand, on the heated evaporator, due to the high-speed turbulence of the film, the product will not be retained on the surface of the evaporator. Therefore, the scraped film evaporator is especially suitable for the evaporation of heat-sensitive materials. For the scraped film evaporator, the decrease of the boiling point of the material increases the temperature difference with the heat medium,rotovap distillation, reduces the thickness of the liquid film in the turbulent state, and reduces the thermal resistance. At the same time, in this process, the material is inhibited from scaling on the heating surface, accompanied by good heat exchange, so the total heat transfer coefficient of the scraper film evaporator is improved. The material continuously enters the scraped film evaporator from the large diameter end, is accelerated and distributed by the scraped film and immediately forms a thin flowing film on the heating surface. The conical film evaporator relies on a centrifugal force applied to the material by the rotor. This centrifugal force has two effective forces, one perpendicular to the heating surface and the other in the direction of the large-diameter end body. The material is accelerated by these forces, and the incoming material ensures that the heating surface is fully wet, independent of the evaporation ratio or feed rate. As a result, local material superheat and thermal degradation in that wiped film evaporator is reduce or completely eliminated. The maintenance of the scraper film evaporator is not difficult. The lubricating oil of its reducer is 40 # engine oil, and its oil filling amount should be within the indicated height. The lubricating oil shall be replaced for the second time within 1 month at the beginning of use, and the lubricating oil shall be replaced once within 3-4 months later. After opening the low seal head, unscrew the bolt at the bottom of the rotor U-shaped groove; At the same time, check and replace the scraper every four months, open the bottom bearing every two months, check the wear of the bottom bearing, replace the bottom bearing if necessary, and regularly soak and clean the inner cylinder with warm water or solvent according to the nature of the material; in addition, add sealing liquid to the mechanical seal cavity once a month,molecular distillation systems, and the sealing liquid is 20 # mechanical oil. The above is all about the operation principle of the scraper thin film evaporator and how to maintain the scraper thin film evaporator correctly.
