Cement building materials
The building materials industry is an important basic industry of the national economy, which is an important support for improving living conditions, managing the ecological environment, and developing a circular economy. China is a major producer and consumer of building materials in the world, with the production of major building materials such as cement and flat glass ranking among the top in the world. In response to the harsh working conditions of cement plants in our country, a solution is provided based on targeted design using the mature analysis and control technology and sampling pretreatment technology of JuNeng Company. In particular, the use of innovative sampling probes with minimal maintenance is more suitable for the harsh working conditions of water, mud, and high dust in our country.
The TR-9100 cement coal powder production process gas analysis system is a specialized online analysis system applied to various coal mills and coal silos to provide early fire warning. This system is specifically designed to detect CO generated by coal powder/coal smoldering or combustion. The system uses a sampling pump to extract gas samples from the coal mill or coal silo through a hard probe. After pre-treatment, the gas samples flow through industrial grade CO and O2 sensors to quickly detect changes in CO and O2 gas concentrations. Even if the CO gas concentration is small, it is a sign of early fire alarm, and the system alarms based on this. The system adopts PLC for automatic control, which has the characteristics of reasonable structure, safe and reliable operation, high degree of automation, less maintenance, and strong self diagnostic protection function.
System characteristics
• The system adopts a four level filtering measure, and the final filtering accuracy reaches 0.1um, meeting the analysis requirements of the analytical instrument;
Equipped with a fast bypass flow path and fast instrument sampling response speed;
• The system pre-treatment adopts automatic condensation for water removal, dust removal, stable pressure, and stable flow design, which can provide high-quality sample gas for the analyzer;
• Equipped with automatic blowing function, it can automatically remove dust on the surface of the probe filter element, extending the service life of the probe;
Adopting PLC control, with high degree of automation and low maintenance workload;
• The system can adopt multi-channel sampling and monitoring designs such as one to two, one to three, etc. (such as mill inlet and outlet, coal powder bin, etc.), which can meet the monitoring needs of different customers;
• Users can choose an explosion-proof design, which adopts a positive pressure explosion-proof cabinet design and can be installed in explosion-proof areas, ensuring safety and reliability;
• Modular system structure design, flexible configuration;
• The system has strong anti-interference performance and high measurement accuracy.
Analysis of High Temperature Gas at Kiln Tail
The TR-9100 cement kiln tail high-temperature gas analysis system is a specially designed dry method high-temperature sampling probe and pre-treatment system based on the high temperature (1200 ℃~1400 ℃), high dust (2000g/m3), and corrosive gases containing sulfur dioxide and alkali at the tail of the cement kiln. Mainly used for monitoring the CO/O2/NOx gas content at the kiln tail, to optimize the quality of clinker, save energy and reduce emissions, and achieve optimal control of production.
System characteristics
• System dry sampling ensures that the sample is not distorted;
• Automatic telescopic sampling probe ensures normal operation and safe operation of the probe;
• Program design for automatic/manual internal and external pulse blowing probes;
• Multi stage filtration and dust removal technology, with a filtration accuracy of>0.5um, ensuring the normal operation of the system;
• PLC and related software technology, achieving various controls, fault self diagnosis, safety alarms, and automatic operations;
• Circulating liquid cooled sampling probe ensures continuous and normal operation at high temperatures;
• Equipped with UPS power supply, it can be safely maintained even after a 30 minute power outage;
• Most of the key components are imported, with high reliability.
Typical applications in the industry
• Shandong Binani Rong'an Cement Co., Ltd.'s daily output of 1200 tons of clinker production line (Sino Indian joint venture);
• 2500 t/d cement production line in Türkiye;
• The Yongxiang cement clinker section of Sichuan Yongxiang Co., Ltd. has an annual production capacity of 1 million tons.
