Lime rotary kiln automation refers to the application of automated control and optimization solutions to lime rotary kiln production process, aiming to optimize the kiln combustion conditions, improve the production efficiency and product quality, while reducing the labor intensity and environmental pollution, thus achieving the purpose of high quality, large-scale and high efficiency production.
一，Lime rotary kiln automation control systems
The automation control system of the lime rotary kiln consists of four parts: information, transmission, regulation and control. Information systems collect data from the kiln work point, use industrial computers to receive and process, and feedback to the whole kiln. The transmission system is composed of a variety of signal transmission lines, and can receive and transmit the signals of sensors, display instruments and control equipment. The regulator adjusts the operation parameters such as temperature, pressure, speed and composition and maintains the optimal operating conditions. The control system includes a variety of motor control, relays and other elements, converting digital control signals into mechanical movement forms.
二，Lime rotary kiln automation process
The two most important indicators of the lime rotary kiln are the ratio of the combustion chamber and the burning time. The rational calculation of these two parameters is determined by the automation process. The physical motion of the kiln operation has been broken down into many subtasks, then converted into a set of instructions that the computer can understand, complete the automation process of the entire kiln, control the temperature of the kiln, adjust the flow rate of kiln air and the size of the kiln flame to reach the ideal operating conditions.
三，Automation of the lime rotary kiln benefits
The implementation of the lime rotary kiln automation technology has the following benefits:
(1) Reduce fuel consumption and lower production costs. Automation can accurately measure and adjust the amount of coal and air entering the kiln, resulting in reduced fuel consumption, significantly reducing energy costs.
(2) Increase kiln output and reduce production cost. The automation technology can optimize the combustion process of the kiln, which can reduce the firing time and improve the output of the kiln.
(3) Stable operation and high safety. Real-time monitoring can detect real-time operating parameters, and automatically issue warnings and safely shut down when it exceeds the standard.
(4) Increasing product quality stability. Automation can continuously stabilize the configured parameters, reduce the risk of low-grade products caused by workmanship and material composition, and improve product quality stability.
四，Conclusion
The engineering of the automation system of the lime rotary kiln enables the kiln to realize automatic control within the specific physical range and improve the production efficiency and safety. The application of automation is a key factor in the modern kiln enterprise, and the use of automation has achieved remarkable results in many refractory brick kilns. Automation is of great significance in stabilizing production and improving product quality.
