第一步：焦化生产检测仪及自动控制系统的介绍
With the increasingly severe environmental protection requirements, the development of automation technology is showing a rapid trend. Common automatic detection and control systems in the chemical industry include carbonization detection and automatic control systems for coking production. The automatic detection and control technology of coke production is mainly used for carbonization and decarbonization processes. The coke kiln process is an important process in the production of coke products. At present, most of the process is manual, which not only wastes manpower, but also affects production efficiency, product quality and environmental standards.Therefore, automatic detection and control of the carbonization process is put forward, which can effectively improve the production efficiency, product quality and environmental protection, and realize the goal of energy saving and emission reduction.
The automatic detection and control system of carbonization production mainly includes sensors, controllers and actuators. The operation process of the system is mainly divided into three parts: 1. Sensors: The sensor collects various physical and chemical parameters related to carbonization on-line during the operation process such as carbon content, temperature, flow rate and pressure. 2. Controller: After the sensor collects the data, it sends the data to the controller for processing and comparison with the preset parameters.3. the actuator: after the data is processed and the comparison is completed, the controller sends a signal to the actuator to adjust the output, so as to achieve the purpose of automatic control.

Using this system of automatic detection and control technology ofcarbonization production, a detailed analysis of dry quenching of cokewill be carried out. Dry quenching is a process to stop carbonization in a short time and cool the coke quickly. The main purpose of dry quenching is to avoid coke oxidation reaction, improve coke strength, reduce product dust and reduce energy consumption. The direct consequence of dry quenching is that ash coalification is not enough, so it is prone to dust. Controlling the temperature of dry quenching can regulate the coalification rate and the oxidation rate of coke, and improve the strength of coke and reduce the dust of products.
Therefore, accurate sensing and control of the temperature of dry quenching is the key to improve product quality. In the process of dry quenching cooling, the system will collect the temperature of dry quenching in real time, and through the controller to compare, adjust the temperature of dry quenching and realize the automatic control of dry quenching temperature according to the preset temperature. In this way, the temperature in dry quenching can be adjusted in real time according to the theoretical coalification and oxidation rate, so as to avoid the occurrence of coking dust and improve the product quality.
第三步：系统和优势
At present, the automatic detection and control system of carbonization production has been applied in large-scale carbonization production. The use of this system has greatly improved production efficiency, reduced production cost, achieved high yield and decreased dust emission.
The automatic detection and control system of carbonization production adopts modern automatic detection and control technology, which has established a complete closed-loop control system for the temperature of dry quenching, including sensors, controllers and actuators. The automatic detection and control system realizes the functions of accurately understanding the temperature change of dry quenching, detecting and controlling the dry quenching temperature in real time according to the preset temperature, and completing the automatic regulation of the dry quenching temperature.
The process of automatic detection and control of dry quenching temperature is mainly realized through the following steps: 1. Sensors collect the temperature of dry quenching in real time and send it to the controller for processing. 2. After the signal is processed, the system compares the actual temperature of dry quenching with the preset temperature.3. After comparison, the control signal is sent to the actuator for adjustment and correction, automatically controlling the temperature of dry quenching.
第四步：系统可靠性和安全性
The automatic detection and control system of carbonization production has the reliability and safety. On the one hand, its core components such as sensors and actuators have high reliability and stable performance. On the other hand, the system has perfect interlocking devices, which can supervise and control the whole process of coke production. Therefore, it can monitor the process of coke production in real time, provide alarm protection for the process, prevent man-made errors, reduce human labor intensity and ensure the safety of production. In addition, the system adopts advanced data acquisition and data processing technology, which can effectively analyze and process the information collected by sensors, effectively control the production process of coking, and provide scientific decision-making basis for production.
