Overview of catalyst materials
The role of a catalyst in a chemical reaction is called catalysis. The catalyst is also called catalyst in the industry.
The composition, chemical properties and quality of the catalyst itself do not change before and after the reaction; the relationship between it and the reaction system is like the relationship between the lock and the key, with a high degree of selectivity (or specificity). A catalyst does not have a catalytic effect on all chemical reactions. For example, manganese dioxide plays a catalytic role in the thermal decomposition of potassium chlorate to accelerate the rate of chemical reactions, but it may not have a catalytic effect on other chemical reactions. Some chemical reactions are not just catalysts. For example, potassium chlorate can be catalyzed by thermal decomposition of magnesium oxide, iron oxide and copper oxide. Moreover, there is not only one catalyst for a chemical reaction. For example, red brick powder or copper oxide can be used as a catalyst when preparing oxygen by potassium chlorate.
Overview of catalyst double cone rotary vacuum dryer equipment
The catalyst double-cone rotary vacuum dryer is a double-cone rotary tank. When the tank is under vacuum, steam or hot water is passed into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. After the wet material absorbs heat The evaporated water vapor is pumped away by a vacuum pump through a vacuum exhaust pipe. Because the tank body is in a vacuum state, and the rotation of the tank body continuously turns the material up and down, so the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.
The catalyst double cone rotary vacuum dryer is a new type of dryer that integrates mixing and drying. Match the condenser, vacuum pump and dryer to form a vacuum drying device. (If the solvent needs to be recovered, the condenser can be omitted) The machine is advanced in design. At the same time, the material also rotates when the container itself rotates, but no material accumulates on the container, so the heat transfer coefficient is high and the drying rate is large, which not only saves energy.
Engineering principle of catalyst double cone rotary vacuum dryer
The catalyst double cone rotary vacuum dryer is a new type of dryer that integrates mixing and drying. Match the condenser, vacuum pump and dryer to form a vacuum drying device. The machine has advanced design, simple internal structure, easy cleaning, all materials can be discharged, and the operation is simple. Can reduce labor intensity and improve working environment. At the same time, as the container itself rotates, the material also rotates and no material accumulates on the wall, so the heat transfer coefficient is high, the drying rate is large, not only saves energy, but also the material is dried evenly and fully, and the quality is good. It can be widely used in the drying of materials in pharmaceutical, chemical, food, dye and other industries. Comply with the requirements of the "GMP" drug management standard.
Features of Catalyst Double Cone Rotary Vacuum Dryer
● When the oil is heated, it adopts automatic constant temperature control, which can dry biochemical products and mineral raw materials, and the temperature can be between 20 ~ 160 ℃.
● High thermal efficiency, more than 2 times higher than ordinary oven.
● Indirect heating, the material will not be contaminated, in line with "GMP" requirements. Equipment maintenance is simple and easy to clean.
Application of double cone rotary vacuum dryer
It is suitable for the concentration, mixing, drying of powdery, granular and fibrous materials in chemical, pharmaceutical, food and other industries (such as biochemical products, etc.), and is more suitable for easy oxidation, volatile, heat sensitive, strong stimulation, Drying of toxic materials and materials that do not allow damage to crystals.
