The method of energy conservation of sludge dryer

 Many people know that everyone is advocating energy conservation and environmental protection. With the country improves the requirements on industrial environmental protection. How to make the sludge dryer realize the energy conservation and emission reduction to reach the goal of environmental protection is an very important problem to the manufacturing enterprises and users. There are several suggestions about the energy conservation and environmental protection for the users as follows.

一、Energy conservation

The purpose of energy conservation is to reduce the energy consumption as much as possible and keep the drying effect of the original sludge dryer. The mainly energy used by the drying equipment is fuel and electric power. If we want to achieve the purpose of energy saving, we can start from follow points. Firstly, reducing the granularity before drying to improve drying efficient, reducing consumption of fuel and reducing the drying time. Secondly, controlling the fuel quality. Exorbitant quality fuel will cause waste, on the contrary, the excessive low quality fuel won’t reach the needed temperature. Thus, we can mix the high quality coal with the low quality coal to use. Thirdly, enhancing the insulation of the cylinder. We can use the thermal insulation material to twine the cylinder of the sludge dryer, which can prevent the loses of heat in the cylinder and improve the drying effect. Fourthly, choosing suitable electrical machine to avoid wasting electric quantity. Last but not least, lubricate the transmission part to reduce friction when the equipment working and reduce the load of using electricity.

二、Emission reduction

Emission reduction is reducing exhaust emission of the sludge dryer. The reason why the atmosphere environment is bad is because the industrial exhaust emission and the automobile exhaust is increasing in recent years. The sludge dryer is equipped cyclones and wet dust collector. Choose the suitable dust removing plant can effectively dispose the exhaust which is produced during the drying process and avoid the atmosphere pollution. 

三、Deodorant.

During the process of drying sludge will produce smell which pollutes air. After add this equipment, this phenomenon will be improved.

Actually, the sludge dryer itself is the environmental protection equipment. It can dry the industrial sludge, domestic sludge and make them into fuel and fertilizer, which reduced the area of land used to pile up the rubbish and effectively use the sludge.
