Industrial television system for temperature measurement of rotary kiln burners

A temperature measuring high-temperature ignition TV is equipped with two cameras, one high-definition camera for observing real-time images inside the kiln, and one infrared camera for measuring the temperature inside the kiln. At the same time, it is also equipped with temperature measuring components, which can automatically exit the kiln when there is an abnormality in the kiln, sudden power outage, high temperature, and gas outage. This protects the industrial television from fire, power on, ventilates, and controls the automatic entry of the kiln after the camera temperature is normal. The ZW-NZ500 internal temperature monitoring high-temperature industrial television system adopts a dual optical path system structure, combining color CCD and near-infrared CCD. By utilizing high-performance imaging technology of color and near-infrared CCD, a "full field real-time monitoring system for surface temperature of furnace workpieces based on color and near-infrared dual CCD" has been developed.

Main technical features

The system can automatically and quickly detect the position of workpieces and surface temperature of materials in industrial furnaces, without being affected by the detection distance. The detection speed and accuracy are high, and the detection range is large. It is of great significance to optimize the process control of cement rotary kiln, improve product quality, save energy and reduce consumption, and improve production. It plays a controlling role in energy conservation, emission reduction, and efficiency enhancement. The temperature measuring industrial television adopts a combination of far-infrared cameras, computer systems, and traditional high-temperature industrial televisions, and the system can display the temperature at any 16 points in the monitoring screen. Traditional video output coexists with thermal image output, with a temperature measurement accuracy of ± 2%, optional 4-20mA output, and alarm for temperature rise or fall in the monitoring area.

The system adopts PLC control technology to automatically control the extension and exit of the camera and lens parts. When there are problems with the system power supply, compressed air supply, and the temperature inside the probe cover exceeds the range, the mechanism can be automatically removed from the furnace, providing automatic protection for the equipment.

The temperature measuring high temperature industrial TV is produced for Zhengzhou Dexter automation equipment. The whole set of equipment consists of camera protection device, actuator device, field component control cabinet, field gas bellows, optical fiber and cable, precision oil-water filter, central control converter and control box, computer host (including temperature measuring software), printer, display, etc. Equipment installation is simple, and each set of equipment only requires 3 days of on-site debugging training to complete.

The simple application software of the temperature measurement type high-temperature industrial television system directly displays real-time images and temperatures of unlimited points and areas within a measurable range on the screen. Individual or organizational alarms provide immediate information. Thermal profile, image storage, differential temperature, real-time and historical data trends and high temperature points, and more functions.

The temperature measurement type high-temperature industrial television system is an infrared digital electronic coupling camera that can be installed on a 400mm wall sleeve inside the kiln with a fault prevention device. The electronic temperature measuring components and electronic coupling imaging technology used in the system are transmitted to the central control through an error free digital transmission system, with a maximum transmission distance of 25km. High definition video combined with unique 60Hz full imaging technology can monitor the operation and quality of fuel and products in real-time, and detect real-time temperature, thereby ensuring the accuracy and operation of the kiln.
