In the process of dehydrating and drying wet materials with dryers, in addition to improving the production output and quality of the dryers, reducing energy consumption is also the key to reducing cost investment for users. So, how can we reduce the energy consumption in the operation of wet material dryer?
1. Improve the combustion efficiency of the heat source of the dryer
At present, the main heat source used in wet material dryer equipment is coal-fired raw materials. If the coal fuel we choose is of low quality, incomplete combustion will occur during combustion, and in severe cases, it will lead to fire extinguishing, which not only affects the smooth progress of the dryer operation, but also affects the drying quality of materials. At the same time, if the operator cannot make the added coal fuel evenly distributed in the combustion chamber, it will easily form fuel accumulation, inhibit the heat and mass transfer process, and reduce the temperature of the flue gas in the dryer barrel, thereby causing waste of resources and increasing energy consumption.
2. Add a suitable dryer lifting plate
The dryer achieves the effect of dehydration and drying through the exchange of wet materials and hot air in the drying cylinder, and the device of the lifting plate in the cylinder can repeatedly throw the materials with the rotation of the drum, and increase the material and heat. The contact area of flue gas promotes strong heat exchange. Therefore, according to the characteristics of the material, an appropriate form of lifting plate device is added in the dryer cylinder to increase the formation of the material curtain, improve the dehydration and drying efficiency of the material, and save energy.
3. Strengthen the sealing of the dryer cylinder
The tightness of the dryer cylinder is very important for heat protection, because the inner wall of the dryer cylinder is mostly exposed to high temperature flue gas except for a small part of the inner wall covered by wet materials. With the drying operation, the heat is bound to be It will be dissipated through the cylinder, which will cause the loss of heat. Therefore, it is very necessary to strengthen the sealing of the cylinder dryer. Usually, we can set thermal insulation materials on the inner and outer cylinder walls to reduce heat loss, improve the utilization rate of heat energy, and reduce energy consumption.
