Coal sludge drying machine can reduce heat source consumption

Many enterprises often use sludge drying machine to dehydrate and improve the quality of coal slime. Because the equipment generally adopts high temperature thermal drying technology, it needs fuel to provide heat energy during operation. As a large-scale mechanical equipment, the fuel consumption accounts for the majority of the equipment operation cost, so many friends are very concerned about the cost of fuel use, so in the normal drying operation, what are the ways to reduce equipment consumption?

First of all, we should pay more attention to the selection of heat source. At present, there are many heat sources for sludge drying machine. Such as boiler flue gas, coal, steam, biomass fuel, fuel oil, natural gas, electricity and so on. When choosing heat source, it is better to consider these aspects comprehensively: 1. Easy to purchase; 2. Low price; 3. Stability and environmental protection. Fuel selection should be based on local conditions and convenient access, so as to avoid fuel interruption, and the price should not be too high. Enterprises with conditions can use boiler flue gas as heat source, which can greatly reduce the equipment operation cost. In the choice of fuel, stability and environmental protection should be considered to prevent accidents.

In addition to considering the fuel, we can also reduce the consumption of heat energy from the following aspects. 1. Properly increasing the air volume and wind speed is helpful to improve the drying speed and reduce the residence time of materials in the cylinder, thus indirectly saving the heat source consumption. 2. Do a good job in the heat preservation and sealing work of the dryer. The whole drying production line is fully sealed, which can greatly reduce the heat loss and dissipation, and help to reduce the loss rate of warm charging in the cylinder. 3, In general, the material is dehydrated by the dehydrator and then dried. The material with lower moisture content is dried faster and the heat consumption is less.

The above are some methods to reduce the heat source consumption of slime sludge drying machine. With the increasing demand for energy saving and environmental protection of the equipment, the "rotary harrow three cylinders multiple-loop" series drying equipment mainly launched by the ZJN environmental protection equipment provides a drying solution for realizing low power consumption, low investment and low moisture content of finished products.
