Description

Technical Field

[0001] The utility model relates to a temperature sensor, in particular to a temperature sensor for a torch light. Background Art

[0002] Chemical plants produce a lot of flammable and explosive gases during the production process, many of which are harmful to the human body. Most of them are heavier than air. If they are directly released into the atmosphere without any treatment, they will spread and deposit on the ground, causing serious environmental pollution and endangering human health. Some of these flammable and explosive substances will cause fires or even explosions if they come into contact with fire. In order to prevent these dangers from happening, they are usually concentrated and burned to prevent future troubles. In the chemical industry, flammable, explosive, toxic, and corrosive gases are burned into harmless carbon dioxide, water, or other non-toxic and less toxic substances through a flare device. In the event of an accident, a large amount of combustible gas can also be burned through it to ensure safety. The flare device can be said to be the last safety barrier of a chemical plant. The flare tower also needs to pay attention to temperature control during the combustion process. When the temperature is too high during the combustion process, the structure of the combustion tower will be deformed and damaged, endangering the safety of the staff.

[0003] With the increasingly sophisticated digital monitoring requirements and special working conditions, the temperature control during equipment operation has become more stringent, mainly including higher and higher requirements on temperature measurement accuracy, thermal response time and service life.

[0004] The temperature sensor for the torch light is a temperature sensor used for measuring the temperature on the torch head of the combustion tower. There are generally three ways to install conventional torch thermometers: 1. The measuring end is inserted into the middle section of the pipeline, 2. The measuring end is installed and fixed on the surface of the pipeline, and 3. The temperature sensor is directly inserted into the combustion point of the torch; the actual temperature measured in installation methods 1 and 2 is not the temperature of the combustion point, but the temperature of the combustion medium before reaching the combustion point. The combustion gas flows outward, which can be regarded as a cold air purge of the temperature measurement point. This will cause the measured temperature to be lower than the actual combustion temperature, and the combustion point temperature cannot be accurately displayed. It may cause the combustion point temperature to be too high, resulting in abnormal damage to the burner. The temperature sensor of installation method 3 is in direct contact with the combustion gas, and the burner often contains flammable, explosive, toxic and corrosive gases, and the high temperature factor can easily damage the sensor.

[0021] like Figure 1-Figure 5 As shown, a temperature sensor for a torch light includes a temperature sensor assembly 100 and a fixing device 300 for mounting the temperature sensor assembly 100 on the side of a burner 200. The temperature sensor assembly 100 includes a temperature sensor 110. The temperature sensor 110 has a mounting section 111 mounted on the side of the burner 200 and a measuring section 112 extending toward the mouth of the burner 200. The temperature sensor 110 is fixed to the burner 200 by the fixing device 300, and the temperature of the flame burning in the burner 200 is monitored by the measuring section 112. Figure 1 The arrow direction in the figure indicates the direction of the flame burning in the burner 200. The sleeve 120 is also provided with a sleeve screw assembly 330 connected to the junction box 130.

[0022] The temperature sensor 110 is wrapped with a sleeve 120 for protecting the temperature sensor 110 . The sleeve 120 protects the temperature sensor 110 . The sleeve 120 can be made of high temperature resistant and corrosion resistant materials.

[0023] The sleeve 120 has a large and a small outer diameter, wherein the outer diameter of the measuring section 112 is smaller than the outer diameter of the mounting section 111. The sleeve 120 is designed to be a reduced diameter structure. Such a setting can reduce the outer diameter of the temperature measuring section sleeve 120, and the matching clearance between the temperature sensor 110 and the sleeve 120 is small, thereby increasing the contact area between the temperature measuring point of the temperature sensor 110 and the inner wall of the sleeve 120, improving the response time and the stability of temperature measurement, and facilitating the adjustment of the bending angle of the sleeve 120 during installation to ensure the correct position of the temperature measuring point. The outer diameter of the mounting section 111 is designed to be a thicker structure, thereby increasing the strength of the sleeve 120 and enhancing the connection with the riding card 320.

[0024] The fixing device 300 includes a fixing plate 310 fixed on the burner 200, and a riding clamp 320 for fixing the sleeve 120 is provided on the fixing plate 310. The sleeve 120 is installed on the fixing plate 310 through the cooperation of the riding clamp 320. The riding clamp 320 can be used to adjust the position of the sleeve 120 as needed to ensure the accurate position of the measuring section 112 of the temperature sensor 110. When the sleeve 120 has an abnormality and needs to be replaced, the disassembly and replacement operation can be completed quickly and easily. The fixing plate 310 can be fixed to the side wall of the burner 200 by screws or welding.

[0025] The saddle card 320 and the fixing plate 310 are fixedly assembled by screw fastening, and the temperature sensor 110 can be conveniently replaced or repaired by screw fastening.

[0026] The riding card 320 is provided with a set screw 321 for reinforcing the sleeve 120. The set screw 321 further reinforces the sleeve 120 and has strong practicality.

[0027] The temperature sensor 110 is a thermocouple structure. The temperature sensor 110 of the present application preferably adopts a thermocouple structure, which has the advantages of high measurement accuracy, wide measurement range and simple structure.

[0028] The temperature sensor 110 has a graduation number of K type, S type, R type or N type.

[0029] The temperature sensor assembly 100 includes a junction box 130 connected to the temperature sensor 110. The temperature sensor 110 realizes voltage signal conversion through the connection terminals or temperature transmitter in the junction box 130. The junction box 130 converts temperature into a voltage signal. In order to enable the thermocouple to be used in conjunction with the instrument, a cable connection is required. The temperature transmitter in the thermocouple junction box 130 is a device that plays a joint connection and protection role. It can amplify, linearize, adjust and isolate the thermocouple signal to make it meet the instrument input requirements.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, simple changes and substitutions by ordinary technicians in this field are within the protection scope of the utility model.
