How to improve the thermal efficiency of sludge treatment dryer?

The low thermal efficiency of the sludge treatment dryer is a major problem that plagues many dryer users. With the passage of time, it has become a technical problem. Today I will introduce to you how to improve the thermal efficiency of the sludge treatment dryer:


1. Improvement of lifting plate

Firstly, the lifting plates of the same shape are staggered and installed; secondly, a combined lifting plate is adopted to promote the drying material to form a complete material curtain on the simplified cross-section of drying under the action of different orientations and different lifting plates, thereby improving Heat transfer effect, reduce heat loss.

2. New high-efficiency crusher with drying

Add a high-efficiency crusher to further dry the crushed materials, and promote the specific surface area of ​​the dryer to increase by 2-3 times. So as to ensure that under the same thermal energy situation, due to the increase in the area of ​​heat exchange between the material and the hot air, the thermal efficiency is increased by 2-3 times.

3. Improvement of drive motor

Switch to a speed-regulating motor, the operator can freely adjust the speed of the dryer within the speed range of 2 ~ 8r / min according to the initial moisture level of the dryer, and the final moisture content of the dried material meets the quality requirements and Save energy.

4. Dryer barrel plus insulation

The drum of the old-style dryer directly touches the outside air, which radiates a lot of heat energy. The dryer manufacturer adopted the method of heat insulation to wrap the barrel with asbestos to avoid unnecessary waste of heat energy. Practice has proved that this measure can save 15% of thermal energy.
