The intelligent vertical kiln has been favored by customers both at home and abroad, for its advantages of energy saving, environment protection, high intelligence, good quality of finished product, low cost and short period for construction. This type high-efficiency and environment-friendly vertical lime kiln is widely used in metallurgy, chemical and other industries, is the best choice for the production of high quality active lime.
Production capacity 100 ~ 550t/d
Product improvement of intelligent energy saving vertical kiln
1, automatic and manual system double standby, in addition to the manual operation of the field operation box, all the operation can also be done with the mouse on the industrial control machine.
2. Intermediate chain relays (except isolated relays) have been cancelled.
3. All two instruments (such as pressure, flow, temperature meter) are cancelled, and all the data are displayed on the computer and printed by the printer.
Advantage characteristics
1, the main equipment (fan, single bucket, feeder, belt, feeder, etc.) all use the inverter to replace the original contactor, improve the performance of the system, reduce the amount of maintenance, and strengthen the reliability of the system.
2, perfect WINCC man-machine interface operating system.
3, reliable lime furnace level gauge and intelligent master and other proprietary use devices.
4, perfect field video surveillance system.
5, reliable SIEMENS PLC, inverter and industrial computer two level microcomputer intelligent system.
Functional introduction of intelligent energy saving vertical kiln
The kiln is mixed with raw fuel, anthracite is used as fuel, can be calcined with coal or lump coal, and exchange reaction between material and hot gas flow, so it is also called reverse flow lime kiln. The kiln's feeding, discharging and operation control, using the most advanced international DCS centralized centralized control system, monitoring the firing process of the shaft kiln, such as ignition, batching, cloth, burning belt, discharge and air supply, etc., to ensure that all the products have high burning rate, less burning, less burning material, stable product quality and oxygen product. High calcium content, high quality lime can be produced. All operations are simple and easy. Every worker in each class can guarantee the operation of the lime kiln and greatly improve the labor productivity.
Application scope of intelligent energy saving vertical kiln
The ordinary mechanical shaft kiln is mechanical feeding and mechanical unloading; the whole calcining system is controlled by people, and the intelligent chain control can not be realized. So the products of the vertical kiln are greatly influenced by the personnel and the quality fluctuates greatly. The intelligent energy-saving vertical kiln is the DCS intelligent central centralized control system to control the working condition parameters of the whole system, such as feeding, unloading, wind pressure, wind speed, kiln temperature and so on. It avoids the influence of human operation factors. In order to keep the quality of the product stable. Intelligent energy-saving kiln production of lime is mainly used in steel, iron, copper, aluminum, building materials and other industries.
