Product name: Sodium methoxide vacuum dryer
Product keywords:氢化钠耙式干燥机|硫酸镁真空干燥机|硼氢化钾干燥机|硼氢化钠烘干设备
Product Profile:Sodium methoxide is added from the top of the top of the sputum dryer. When the sodium methoxide is in contact with the shell wall of the sputum dryer under the stirring of the rotating molars, the surface is continuously renewed, and the sodium methoxide is indirectly heated by steam. The sodium methoxide is vaporized, and the vaporized water is pumped away by the vacuum pump in time. The sodium methoxide dryer can simultaneously use the sandwich and the molar heating method, and the heat transfer area is larger, and the thermal efficiency is higher, so that the drying efficiency is higher. Due to the high degree of operating vacuum, the water vapor pressure on the surface of sodium methoxide is much larger than the water vapor pressure in the evaporation space in the sodium methoxide dryer casing, which is beneficial to the discharge of internal moisture and surface moisture of sodium methoxide, which is beneficial to the water molecule movement of sodium methoxide. To achieve the pu
Sodium methoxide is a white amorphous, flowable powder. It is easy to react with oxygen. It decomposes into moisture and water to methanol and sodium hydroxide, and decomposes in air above 126 °C. Soluble in methanol and ethanol. Insoluble in benzene and toluene. Mainly used in the production of vitamin A1 vitamin B1 long-acting sulfonamide, sulfadiazine, trimethoprim and other pharmaceutical industries, but also for the biodiesel industry. It can also be used as an edible catalyst and analytical reagents and cosmetics.
1. Sodium methoxide vacuum dryer - working principle
Sodium methoxide is added from the top of the top of the sputum dryer. When the sodium methoxide is in contact with the shell wall of the sputum dryer under the stirring of the rotating molars, the surface is continuously renewed, and the sodium methoxide is indirectly heated by steam. The sodium methoxide is vaporized, and the vaporized water is pumped away by the vacuum pump in time. The sodium methoxide dryer can simultaneously use the sandwich and the molar heating method, and the heat transfer area is larger, and the thermal efficiency is higher, so that the drying efficiency is higher. Due to the high degree of operating vacuum, the water vapor pressure on the surface of sodium methoxide is much larger than the water vapor pressure in the evaporation space in the sodium methoxide dryer casing, which is beneficial to the discharge of internal moisture and surface moisture of sodium methoxide, which is beneficial to the water molecule movement of sodium methoxide. To achieve the purpose of drying.
Sodium methoxide itself has a certain degree of corrosiveness. In the process of drying sodium methoxide, the anti-corrosion requirements of the equipment and the sodium methoxide drying setting need to be strictly set. The sodium methoxide drying equipment designed and manufactured by Changzhou Yidu Drying Equipment Co., Ltd. is based on the characteristics of sodium methoxide drying and physical and chemical properties, and has the following advantages:
(1) It has strong adaptability and is used in the production process of each sodium methoxide. Because the sodium methoxide dryer utilizes jacket heating and high vacuum exhaust, it is suitable for almost all wet methanol with different properties and different states. It can be said that it is the preferred drying equipment for dealing with such corrosive and flammable materials.
(2) Good quality of sodium methoxide product Because the sodium methoxide is continuously rotating in the process of drying, the sodium methoxide is evenly stirred, avoiding the overheating of sodium methoxide during the drying process, and the moisture is easy to escape, and the shell is obtained. Low temperature sodium methoxide product. Since sodium methoxide has a fine particle size, it can be packaged without pulverization.
(3) The steam consumption is small. Because the sodium methoxide dryer uses steam to pass into the jacket, the material is heated by latent heat, and the steam consumption per kilogram of sodium methoxide finished product is small, generally 1.3-1.8 kg steam.
(4) The sealing system of sodium methoxide dryer can choose two kinds of packing seal and mechanical seal. The special design guarantees the sealing and service life.
(5) Easy to operate, the sodium methoxide dryer is easy to operate, has less staff and low labor intensity. Environmental sanitation is improved due to reduced fumigant loss of sodium methoxide.
