[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4As shown in this embodiment, a real-time monitoring device for high-temperature environment of nickel alloy tube includes an infrared thermal imager 1. The infrared thermal imager 1 has several interfaces 7 at its tail. An outer protective shell 2 is provided on the outside of the infrared thermal imager 1. The inner part of the outer protective shell 2 has a storage groove 3 for accommodating the infrared thermal imager 1. A rear end cover 4 is provided at the rear end of the outer protective shell 2. An illumination hole 15 is provided at the front end of the outer protective shell 2. A sandwich layer is provided inside the outer protective shell 2. A water inlet 11 and a water outlet 12 are respectively provided on both sides of the outer wall of the outer protective shell 2. The water inlet 11 and the water outlet 12 are respectively connected to the sandwich layer. Three fixing plates 8 are also fixedly installed on the outer wall of the outer protective shell 2. Fixing holes 9 are provided on the fixing plates 8. The three fixing plates 8 are arranged in a ring array.

[0021] In use, place the infrared thermal imager 1 into the storage slot 3 of the outer housing 2, close the rear cover 4, and connect the water inlet 11 and the water outlet 12 to the water inlet pipe and the water return pipe of the water chiller, respectively. The water inlet pipe and the water return pipe of the water chiller need to be wrapped with a heat insulation layer of fiberglass material, or fiberglass material can be used directly for the water inlet pipe and the water return pipe. The model of the water chiller is TASI TC-5000, which has a built-in water pump and water tank. The water chiller can circulate the cooling water into the interlayer of the outer housing 2 to insulate and cool the infrared thermal imager 1. The outer housing 2 is made of 316L stainless steel, which has good corrosion resistance and high temperature resistance.

[0022] When installing the device on the furnace body, the installation location needs to be determined comprehensively based on the furnace structure, the detection target, and the thermal imaging principle. The core principle is to ensure that the lens can clearly capture the thermal radiation signal on the surface of the furnace tubes and avoid obstruction, high temperature, and flue gas interference. For example, when installing the device on a box furnace, it can be placed near the observation hole or maintenance port on the side or top of the furnace body, or a dedicated detection window can be opened on the furnace wall. Since the furnace tubes of a box furnace are mostly arranged horizontally, installation on the side or top allows for direct viewing of the furnace tube array, avoiding obstruction by flames or furnace walls.

[0023] During installation, holes need to be drilled at the installation location on the furnace body. The front end of the outer protective shell 2 is inserted into the hole, and the outer protective shell 2 is fixed to the installation location on the furnace body by the cooperation of the external fixing screws and the fixing plate 8.

[0024] The outer casing 2 has an annular groove 10 at its front end.

[0025] The annular groove 10 is used to accommodate the sealing ring. When the outer protective shell 2 is installed in the hole of the furnace body, the sealing ring can play a sealing role. The material of the sealing ring can be selected according to the highest temperature of the furnace body, such as fluororubber, silicone rubber, etc.

[0026] Among them, the inner wall of the outer protective shell 2 is provided with a threaded hole 5 at the opening of the storage groove 3, and the bottom of the rear cover 4 is fixedly connected with a threaded post 6, which is threadedly engaged with the threaded hole 5.

[0027] The rear end cover 4 can be fixed to the outer housing 2 by the threaded engagement of the threaded post 6 and the threaded hole 5.

[0028] The height of the threaded post 6 is equal to the depth of the threaded hole 5, and the height of the infrared thermal imager 1 is equal to the height of the storage slot 3.

[0029] With this configuration, once the rear cover 4 is installed, the threaded post 6 can just hold the infrared thermal imager 1 in place, preventing the infrared thermal imager 1 from becoming loose.

[0030] The rear end cover 4 has multiple anti-slip seams 13 on its outer wall, which are arranged in a ring array. The rear end cover 4 also has through holes 14 that penetrate itself and the threaded post 6.

[0031] Multiple anti-slip seams 13 can increase the friction between the user's hand and the rear cover 4. The through holes 14 can be used to easily connect the external wiring harness to the interface 7 of the infrared thermal imager 1. The interfaces 7 have different functions, such as connecting to an external power supply or an external display screen. The outermost layer of the external wiring harness must be made of fiberglass.

[0032] Quartz glass is fixedly embedded inside the irradiation hole 15.

[0033] By using quartz glass, the lens of the infrared thermal imager can be isolated from the high-temperature environment while still allowing infrared light to pass through.

[0034] This utility model provides a real-time monitoring device for high-temperature environments of nickel alloy tubes, the specific working principle of which is as follows:

[0035] Among them, the infrared thermal imager 1 is model FLIR A615. When using it, place the infrared thermal imager 1 into the storage slot 3 of the outer protective shell 2, close the rear end cover 4, and connect the water inlet 11 and water outlet 12 to the water inlet pipe and water return pipe of the water chiller, respectively. The water inlet pipe and water return pipe of the water chiller need to be wrapped with a heat insulation layer of glass fiber material, or glass fiber material can be used directly for the water inlet pipe and water return pipe. The water chiller is model TASI TC-5000, which has a built-in water pump and water tank. The cooling water can be circulated into the interlayer of the outer protective shell 2 through the water chiller, thereby providing heat insulation and cooling for the infrared thermal imager 1. The outer protective shell 2 is made of 316L stainless steel, which has good corrosion resistance and high temperature resistance.

[0036] When installing the device on the furnace body, the installation location needs to be determined comprehensively based on the furnace structure, the detection target and the thermal imaging principle. The core principle is to ensure that the lens can clearly capture the thermal radiation signal on the surface of the furnace tubes and avoid obstruction, high temperature and flue gas interference. For example, when installing the device on a box furnace, it can be near the observation hole or maintenance port on the side or top of the furnace body, or a dedicated detection window can be opened on the furnace wall. Since the furnace tubes of a box furnace are mostly arranged horizontally, installation on the side or top can directly view the furnace tube array and avoid obstruction by flames or furnace walls.

[0037] During installation, holes need to be drilled at the installation location of the furnace body. The front end of the outer shell 2 is inserted into the hole. The outer shell 2 is fixed in the installation position of the furnace body by the cooperation of the external fixing screws and the fixing plate 8. A sealing ring is set between the hole and the outer shell 2 for sealing. The material of the sealing ring can be selected according to the highest temperature of the furnace body, such as fluororubber, silicone rubber, etc.

[0038] After installation, the infrared thermal imager 1 captures the temperature distribution on the pipe surface, identifies local overheated areas (such as abnormally high temperatures where the oxide layer peels off), and displays the temperature distribution directly in image form on an external display screen. This makes defect location intuitive and facilitates quick troubleshooting.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
