Introduction
Our triple pass dryer has the advantages of compact, simple and rational structure, high heat exchange efficiency, reliable operation, low energy consumption, high heat efficiency, and more.Features
1. It can do heat preservation by itself, and its heat efficiency can be as high as 80%, while the heat efficiency of single-cylinder dryer is only 35%. Besides, it can save as much as 68% coal and its productivity is 100% higher.2. Its length is 60% shorter than that of single-cylinder dryer, which makes it easy to arrange. It only takes up about 20m2.
3. Its alloy steel plate is heat and wear resistant, and its abrasive performance is 4 times of that of general steel plate. Besides, it has longer service life and is easy and convenient to maintain.
4. Its outer cylinder has a temperature lower than 60℃, while the temperature of the outer cylinder of single-cylinder dryer can be as high as 150℃. And the discharge temperature is lower than 60℃.
5. The temperature of its discharge hole is low, which helps to prolong the service life of environmental protection equipment, and it can also work together with air tank pulse bag filter.
6. Its air heating furnace can also work in conjunction with fluidized bed furnace, coal spray furnace, and gas furnace.
