Description

Technical Field

[0001] This utility model relates to the field of gas detection technology inside furnaces, specifically to a probe-type high-temperature gas analyzer. Background Technology

[0002] When processing in a high-temperature furnace, it is necessary to detect the gas inside. Due to the excessively high temperature inside the furnace, the gas analyzer can easily damage the precision components inside the furnace after being inserted. Therefore, water-cooling components are installed inside the gas analyzer to extend its service life. However, the cooling effect of this method is not high and cannot meet the requirements. Therefore, it is particularly important to design an immersion-type high-temperature gas analyzer to solve the above problems. Summary of the Invention

The left and right ends of the storage cavity are sealed by the left end cap and the right end cap, respectively. A through hole is opened on the left end cap, which is directly opposite the main body of the gas analyzer. The detection end of the gas analyzer main body detects gas through the through hole on the left end cap. The coolant storage cavity between the inner tube and the outer tube is also equipped with two carbon-based composite thermal insulation jackets, which divide the coolant storage cavity into three coolant channels from the inside to the outside. The carbon-based composite thermal insulation jackets are also provided with notches for connecting two adjacent coolant channels.

[0005] Furthermore, the outer tube body is provided with three layers from the outside to the inside, the outermost layer being a rare earth tantalate thermal barrier coating, the middle layer being a first stainless steel layer, and the innermost layer being a first carbon-based composite thermal insulation layer.

[0006] Furthermore, the inner tube body is composed of two layers, an outer layer being a second carbon-based composite thermal insulation layer and an inner layer being a second stainless steel layer.

[0007] Furthermore, the coolant flow channel is filled with liquid metal coolant, and a liquid metal coolant circulation inlet and a liquid metal coolant circulation outlet are provided on the side wall of the outer tube near the right end cap. The liquid metal coolant circulation inlet is connected to the outermost coolant flow channel, and the liquid metal coolant circulation outlet is connected to the innermost coolant flow channel.

[0008] The beneficial effects of this invention, achieved by adopting the above structure, are as follows: The invention features a rare-earth tantalate thermal barrier coating on the outside of the outer tube.
