Do You Know the Decomposition Rate of Active Lime Rotary Kiln? Know Chute Technology?时间：2021-11-20 作者 ：超级管理员
The application of active lime rotary kiln has been popularized, giving full play to the role of active lime rotary kiln. Do you know the decomposition speed of active lime rotary kiln? Know chute technology? Introduce the decomposition speed of active lime rotary kiln and the improvement of the chute.
In the case of the temperature in the active lime rotary kiln, the gas composition in the kiln and the stone, the depth of the decomposition layer of the stone is also the same, so it is required that the particle size of the stone added at the same time should not be too different, the large particle size and the small particle size The ratio should be controlled within two. Otherwise, it is easy to overburn in high temperature environment after the decomposition of the stone with a smaller particle size, while the underburning caused by the stone with a larger particle size is not completely decomposed, which will affect the quality of the product.
When the active lime rotary kiln roasting technology and the new active lime rotary kiln equipment, because the temperature in the active lime rotary kiln is relatively uniform, the combustion temperature is higher than the material roasting temperature, between 1,100 and 1,300. At this time, the roasting temperature of the material in the active lime rotary kiln is usually about one thousand and one hundred at the high temperature that the roasting can withstand, because the roasting time of the stone in the active lime rotary kiln is shorter and the output is increased.
The kiln tail chute of the active lime rotary kiln is a very important part of the production components. In order to achieve the desired effect, the kiln tail chute is improved. For the inclination angle of the kiln tail chute of the active lime rotary kiln, this plays a key role in the development and use of our active lime rotary kiln equipment. We will be more accurate after the transformation, and can more accurately realize the conversion of our materials; The material of the equipment has been improved. Everyone knows that the material can produce good equipment, so the material is the primary task for us to make a good active lime rotary kiln kiln tail chute; for the active lime rotary kiln kiln tail For the length of the chute, our main consideration for the length problem is ease of installation, not only this aspect, but also greatly reduces the difficulty of our use and maintenance.
Process operation requirements of active lime rotary kiln
At the kiln head of the active lime rotary kiln, the joint between the rotating cylinder and the fixed movable kiln head; at the end of the active lime rotary kiln, the joint between the rotating cylinder and the fixed smoke chamber must have gaps. The active lime rotary kiln is operated under negative pressure. In order to prevent outside air from being sucked in, and to stabilize the thermal system in the kiln, a sealing device must be installed at each of the above two locations.
In the process operation of the active lime rotary kiln, it is required to maintain a proportional relationship among the air volume, fuel volume and material volume in order to stabilize the thermal system, thereby improving the production quality of the active lime rotary kiln. Therefore, it is important to seal the active lime rotary kiln shell and kiln head as well as the shell and kiln tail. If excessive cold air leaks into the kiln head, the amount of secondary air entering the kiln from the clinker cooling equipment will be reduced, and the temperature of the secondary air will be lowered. This will not only cause poor cooling of the clinker, but also the flame in the active lime rotary kiln. The temperature will also decrease, which will affect the fuel combustion rate and increase heat loss. If the tail of the active lime rotary kiln leaks, because this place is a place where the negative pressure of the whole kiln is large, it is easy to inhale a large amount of cold air, and a large amount of gas in the active lime rotary kiln is not easy to be discharged, resulting in the incomplete combustion of the fuel. The thermal system is destroyed, and fuel consumption is increased, and the production quality of the active lime rotary kiln is also reduced. At this time, if the proportional relationship between air volume, fuel and materials is still to be maintained, the load of the exhaust fan needs to be increased to increase power consumption. At the same time, because the air at this place contains powdery materials, a large amount of dust will overflow from occasional downwind, which will affect the hygiene of the workshop. Therefore, the design of the kiln end sealing device of the active lime rotary kiln has higher requirements than the design of the kiln head sealing device.
