Reasons for affecting the speed of drying and dewatering of slime dryer materials
First, the heat temperature factor. The dewatering and drying of the slime dryer is mainly the result of heat transfer under high temperature conditions. The sufficiency of heat supply and the constant temperature are the key factors to ensure the dewatering and drying speed of the slime dryer. In the actual operation process, if the heat supply of the hot blast stove is insufficient, or the heat transfer pipeline leaks air and the heat preservation of the cylinder is not good, the heat in the cylinder body is insufficient, thereby reducing the heat and mass transfer effect of the slime.
Second, the internal structure of the equipment. Due to the inherent characteristics of the slime, various lifting plates and cleaning and dispersing devices are generally installed on the inner wall of the cylinder, which not only enhances the heat transfer effect, but also prevents the sticky concrete from sticking to the wall, thereby improving Sludge dryer dehydration drying speed.
Third, the difference in heating methods. The heat source in the slime dryer production line can be divided into two types: indirect heating and direct heating. When we use indirect heating, the cleanliness of hot air is relatively high, but the thermal efficiency is correspondingly lower, which will reduce coal. The dewatering and drying speed of the mud is more suitable for the treatment of materials that cannot be mixed with soot. In the direct heating process, the material may be affected by dusting, but the utilization rate of heat energy is high, and the speed of dehydration and drying of the slime dryer will also be accelerated.
Fourth, the impact of material characteristics. In our dry treatment of coal slime, the particle size, moisture level, and viscosity of the material have a certain impact on the dewatering and drying speed of the slime. Especially in the process of coal slime heat exchange, the gasification of water mainly occurs on the surface of the material particles, so the lower the water content of the slime, the stronger the fluidity in the cylinder, the better the dewatering and drying speed and effect of the slime. .
The above four points are the reasons for the speed of drying and dewatering of the material of the slime dryer. Knowing the reason allows us to make better use of the slime dryer in future production. Contact electricity.
