Description

Technical Field

[0001] This utility model relates to the field of flame detection technology, and specifically to a flame detection system with high detection accuracy. Background Technology

[0002] The state of the flame at the converter mouth is a crucial indicator of the furnace's internal condition. Traditional flame detection methods rely on manual visual observation, but due to the extremely high temperature of the flame at the furnace mouth, prolonged observation by the human eye is difficult, and the flame characteristics change rapidly, making it challenging to accurately assess the steelmaking process. Therefore, a flame detection system can acquire real-time flame images using a high-definition camera, helping workers accurately monitor the steelmaking process, prevent over-refining or under-refining of molten steel, thereby improving steel quality and reducing energy consumption.

[0003] For example, Chinese patent CN207010836U discloses a gasifier flame detection system, belonging to the field of coal gasification technology, which is used to solve the problems of unstable flame detection and lack of accurate and fast switching signals in existing gasifiers. The gasifier flame detection system includes: an image probe arranged at the central opening of the gasification burner outside the gasifier body; the image probe is surrounded by an explosion-proof pressure-resistant shell; the video output end of the image probe is connected to a video processing component; the video processing component controls the image probe to acquire the video signal at the central opening of the burner and identify whether there is a flame.

[0004] However, the technology has the following problems: the above technology uses an image probe to detect the flame, but the smoke inside the furnace is relatively large, which will affect the image probe's ability to capture the flame.

[0005] Based on this, this utility model designs a flame detection system with high detection accuracy to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a flame detection system with high detection accuracy.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-precision flame detection system includes a central processing unit, as well as a flame detection module, a monitoring module, a cooling purging module, an early warning module, a communication module, and a terminal;

[0009] The central processing unit is electrically connected to the flame detection module for detecting the flame status inside the furnace, the monitoring module for monitoring the flame detection module and the converter monitoring window, the cooling purging module for purging the converter monitoring window, and the early warning module for alarming and notifying the staff. The central processing unit is electrically connected to the communication module, and the communication module is wirelessly connected to the terminal.

[0010] The cooling purging module is installed on the top of the converter, and the air outlet of the cooling purging module faces the converter monitoring window.

[0011] Furthermore, the flame detection module includes a flame detection probe for detecting flames and a temperature sensor for detecting the temperature inside the converter. Both the flame detection probe and the temperature sensor are electrically connected to the central processing unit. The flame detection probe is fixedly installed outside the converter and faces the converter monitoring window, while the temperature sensor is fixedly installed at the converter air outlet.

[0012] Furthermore, the monitoring module includes a high-definition camera and an angle adjuster. The angle adjuster is fixedly installed on the outer wall of the converter, and the high-definition camera is fixedly installed on the adjustment end of the angle adjuster.

[0013] Furthermore, the high-definition camera and angle adjuster are both electrically connected to the central processing unit.

[0014] Furthermore, the cooling and purging module includes a cooler, a one-way valve, a one-way valve regulating device, a fan, and an air inlet pipe. The cooling end of the cooler is connected to the outer wall of the air inlet pipe, the air inlet pipe is connected to one end of the one-way valve, the other end of the one-way valve is connected to the air inlet of the fan, the air outlet of the fan faces the converter monitoring window, and the output end of the one-way valve regulating device is fixedly connected to the one-way valve. The cooler, one-way valve, one-way valve regulating device, fan, and air inlet pipe are all fixedly installed on the outside of the converter.

[0015] Furthermore, the cooler, one-way valve regulating device, and fan are all electrically connected to the central processing unit.

[0016] Furthermore, the early warning module includes a horn and an alarm light, both of which are fixedly installed on the outer wall of the converter.

[0017] Furthermore, the horn and alarm light are both electrically connected to the central processing unit.

[0018] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses a flame detection probe to detect the flame inside the converter and a temperature sensor to detect the temperature inside the converter. A high-definition camera monitors the smoke on the converter monitoring window. If the smoke on the converter monitoring window exceeds the threshold set in the system, the central processing unit controls the cooler and fan to start, blow away the smoke on the converter monitoring window, and cool down the converter monitoring window. The temperature sensor collects the temperature inside the furnace and uploads it to the central processing unit. The central processing unit adjusts the opening and closing degree of the one-way valve according to the temperature control one-way valve adjustment device inside the converter, thereby cooling down the converter monitoring window.

[0019] If the flame detection probe uploads the flame detection status to the central processing unit in real time, the central processing unit will compare the detected flame status with the flame images stored in the central processing unit. If the flame status is found to correspond to the image of the abnormal flame status, the horn and alarm lights will be activated to notify the staff to come to the scene to check the situation.

[0020] The angle adjuster drives the high-definition camera to monitor the detection surface of the flame detection probe. If the dust coverage on the surface of the flame detection probe exceeds the threshold set in the system, the horn and alarm light will sound an alarm to notify the staff to clean the flame detection probe.
