Temperature, pressure and combustion state monitoring device of high temperature furnace

Abstract

The invention relates to a temperature, pressure and combustion state monitoring device of a high temperature furnace. The temperature, pressure and combustion state monitoring device comprises a high temperature resistant video camera, an image processor and a controller. The image processor is connected with the high temperature resistant video camera and the controller and analyzes combustion images shot by the high temperature resistant video camera to obtain and output the quantity of a plurality of flames in the combustion image and the combustion state of each flame. The controller performs flame extinction alarming according to the quantity of the plurality of flames and the combustion state of each flame. The temperature, pressure and combustion state monitoring device further comprises a component used for detecting and controlling temperature and pressure in the high temperature furnace. The temperature, pressure and combustion state monitoring device can monitor a plurality of parameters in the high temperature furnace so as to fast give alarms when abnormal conditions appear and improve use safety of the high temperature furnace.

Description

technical field [0001] The invention relates to the field of monitoring, in particular to a monitoring device for temperature, pressure and combustion state of a high-temperature furnace. Background technique [0002] High-temperature furnaces are mainly used for heating and heat treatment in laboratories of various industrial and mining enterprises and scientific research units, and are indispensable instruments and equipment in various laboratories. While the high temperature furnace provides convenience for human beings, it also brings some safety hazards because of its high temperature and high pressure characteristics. Therefore, a monitoring system is equipped for the high temperature furnace to detect the parameters inside the high temperature furnace, and take emergency measures in case of abnormal conditions, so as to avoid Serious disaster happened. [0003] However, the existing high-temperature furnace monitoring system generally has a single structure, or only ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing high-temperature furnace monitoring system generally has a single structure, or only detects and controls the internal temperature of the high-temperature furnace, or only detects and controls the internal pressure of the high-temperature furnace. At the same time, it lacks monitoring devices for the combustion state of the burner. It is often impossible to judge the cause of the ceasefire after a period of ceasefire. In addition, the alarm method for abnormal situations is relatively simple. Generally, the abnormal parameter value is only displayed for the operator to judge whether to deal with it, and the intelligence is not high.
