What are the factors that affect the performance of printing and dyeing sludge drying equipment

With the continuous development of printing and dyeing industry, more and more printing and dyeing sludge is produced, so many people begin to pay attention to the treatment and disposal of printing and dyeing sludge. Printing and dyeing sludge has the characteristics of high water content, viscosity and complex composition. Because it contains dyes, size, additives and various heavy metal elements, it pollutes the environment strongly and belongs to hazardous waste. At present, the first thing to be solved in printing and dyeing treatment is the problem of dehydration and drying. Printing and dyeing sludge drying equipment can quickly dehydrate the sludge with high humidity and viscosity, and its work efficiency is directly related to the output of the whole production line and the user's income. Therefore, many friends will be concerned about the output of the equipment when introducing the printing and dyeing sludge drying equipment. What are the factors that affect the working performance of the printing and dyeing sludge drying equipment?

1. Hot air temperature. Printing and dyeing sludge drying equipment is mainly through the hot air and wet sludge full contact, strengthen the heat and mass transfer effect, and make the wet sludge steaming water process. With the increase of hot air temperature, the moisture of the material inside the dryer will evaporate rapidly, which can greatly improve the efficiency of the printing and dyeing sludge drying equipment. On the contrary, if the heat supply is insufficient, the cylinder temperature will be too low, which will not only prolong the drying time of materials, but also greatly reduce the output of equipment and drying quality. It can be seen that the hot air temperature is one of the important factors affecting the performance of the equipment.

2. Hot air speed. The movement speed of hot air in the cylinder is also an important factor affecting the working performance of printing and dyeing sludge drying equipment. Too fast or too slow hot air speed is not suitable, because when the hot air speed reaches a certain value, the drying speed of materials will decrease, and the heat loss of equipment will increase. Therefore, to improve the performance of the equipment, it is necessary to control the hot air speed properly.

3. Feeding speed and moisture content. In the operation process of printing and dyeing sludge drying equipment, the feeding speed and moisture content of the feeding affect the working performance of the dryer equipment to a great extent. Operators need to feed evenly and reasonably according to the regulations, and control the moisture content of materials in a reasonable range. If the moisture content of the material is too high, or the feeding is too fast, it will lead to excessive accumulation of the material in the cylinder to a great extent, and even blockage, which is not conducive to the dehydration effect and speed. When the feed is too little, not only the performance of the equipment is not brought into full play, but also the energy consumption is increased and the drying transition of materials is caused. Therefore, the feeding speed and moisture content need to be well controlled, which will directly affect the performance of the equipment.
