Description

Technical Field

[0001] This utility model relates to the field of temperature monitoring technology, and in particular to an infrared-based furnace temperature field monitoring device. Background Technology

[0002] Industrial furnace temperature monitoring is a key link in ensuring production safety and energy efficiency. In metallurgical, chemical and power industries, even slight fluctuations in furnace temperature can trigger a chain reaction. Temperature runaway can lead to equipment damage, production accidents and a surge in energy consumption. Accurate monitoring can capture anomalies in real time, avoid the risk of explosion due to overheating, and optimize combustion parameters to allow fuel to react fully within the optimal temperature range, reducing energy waste and pollutant emissions.

[0003] A search revealed Chinese Patent Publication No. CN219437437U, which discloses an infrared furnace temperature field monitoring device. The device includes a furnace chamber and a monitoring device comprising: a housing fixedly connected to one side of the furnace chamber; a reflector fixedly connected to the inner wall of the housing; and an infrared receiver fixedly installed on the inner wall of the housing. The monitoring device detects the temperature inside the furnace chamber using the infrared transmitter of an infrared thermometer. The infrared light is then refracted by the reflector and transmitted to the infrared receiver for numerical monitoring. The monitored values ​​are displayed on the control panel screen, thus completing the monitoring of the internal temperature field of the furnace chamber. This facilitates real-time detection and control by personnel, is easy to use, and has a simple structure. This infrared furnace temperature field monitoring device is highly practical and easy to promote.
