Working principle of active carbon production by sharp
Activation Furnace 1 (one of
Activated Carbon Production Equipment)
Introduction: production of activated carbon in sharp furnace
The
Activated Carbon Equipment, the sharp activation furnace, has been widely used in medical and drinking water purification and other fields from ancient Egypt to China to Europe from more than 3000 BC to thousands of years in the 19th century. However, the lack of adsorption capacity in the field of sugar decolorization has become the biggest obstacle to the comprehensive application in industrial production and life. The continuous efforts of scientists make the birth of activated carbon possible. The early research results show that: coal carbonization process can produce strong adsorption coke; coke adsorption has an upper limit, which can not meet the needs of industrial production such as sugar decolorization; high temperature in the process of carbonization will reduce porosity and specific surface area, thus reducing the adsorption.
At the beginning of the 19th century, it was found that activated carbon was prepared by steam and carbon dioxide activation, and the activated carbon with great adsorption was finally born. In the initial period of time, activated carbon was monopolized by the army, and it was completely used for gas masks and water purification. Until the end of the first World War, the expansion of activated carbon production made it possible for civil activated carbon.
In 1966, Taiyuan started the plant of slap activation process, and then hundreds of slap activation furnace plants were opened in China. This furnace is an activated carbon production furnace invented by the Soviet Union. It is used to further drill holes for carbonized coke particles by using steam and a small amount of carbon dioxide, so as to increase the porosity and greatly increase the specific surface area, so as to become the activated carbon with excellent adsorption performance.
