How to reduce the operation energy consumption of large sludge drying equipment

When using large-scale sludge drying equipment, if users want to reduce equipment investment, they can not only increase production output and reduce fault, but also reduce energy consumption during equipment operation. How can large-scale sludge drying equipment achieve energy reduction and consumption reduction? The following section introduces heat source, equipment technology, thermal insulation performance and other aspects, hoping to introduce the current use A friend's device helps.

Methods of reducing energy consumption of large sludge drying equipment

1. In terms of fuel

At present, the heat sources of large sludge drying equipment include coal, fuel, natural gas, biomass fuel, boiler exhaust, steam, etc. Users can choose the fuel with high cost performance according to their own production situation and the convenience of access. In addition, if the quality of the selected fuel is poor, it is easy to cause insufficient combustion during combustion, which not only affects the normal and smooth operation of large sludge drying equipment, but also affects the drying quality of materials.

After selecting the fuel with high cost performance and good quality, the equipment operators also need to add fuel according to the regulations in daily work. If the fuel is not evenly distributed in the combustion chamber, it is easy to form fuel accumulation, thus reducing the effect of heat and mass transfer, thus increasing the energy consumption of equipment operation.

2. Appropriate equipment and technology

Large scale sludge drying equipment achieves the effect of dehydration and drying through the heat exchange of wet materials and high temperature hot air. In the process of drying, what kind of lifting plate is installed inside the equipment is very important for energy saving and consumption reduction. In general, the three-layer sleeve is a ZJN large-scale sludge drying equipment. The reformed "rotary harrow" crushing device and densely distributed combined lifting device are installed inside, which can continuously throw the scattered materials up and down, thus increasing the contact area between materials and hot air, and strengthening the heat exchange effect. Therefore, compared with the traditional single drum, the three drum ZJN large sludge drying equipment is more energy-saving and environmental protection.

3. Strengthen the insulation and sealing performance of the cylinder

The sealing performance of large sludge drying equipment is also very important to reduce the energy consumption of the equipment. With the normal operation of drying operation, the continuous loss of heat in the cylinder can not be avoided, which will lead to the increase of heating cost. Therefore, the insulation performance and sealing performance of large sludge drying equipment should be considered in the design. Three roller structure can be adopted, the length of equipment can be reduced, and the heat insulation material can be set outside the cylinder wall to reduce the heat consumption.
