Problems solved by technology
[0007] Aiming at the problem that the length of the straight tube heat exchange tube cannot be freely expanded and contracted when it expands with heat and contracts with cold, the present invention aims to provide a heat exchange tube device with a length compensation function, which can realize thermal expansion of the heat exchange tube. Freely expand and contract in the length direction when cold shrinking

Embodiment Construction
[0022] Such as figure 1 As shown, a heat exchange tube device with a length compensation function is used in a catalyst bed, including a heat exchange tube 1, and also includes a sleeve 2 arranged in the catalyst bed, and the sleeve 2 includes a The accommodating cavity 21 where the heat exchange tube 1 extends into; a sealing area is formed between the upper end of the sleeve 2 and the heat exchange tube 1; the sealing area may be the upper inner side wall of the sleeve 2 and the bottom of the heat exchange tube 1 It may also be formed between the upper end of the sleeve 2 and the outer wall of the heat exchange tube 1 . The bottom of the sleeve 2 is sealed. The sleeve 2 includes a sealing plate 22 and a bracket 23 , the sealing plate 22 is mounted on the bottom of the sleeve 2 , and the bracket 23 is welded and fixed on the outer upper end of the sleeve 2 .
[0023] When the temperature of the catalyst bed 3 changes drastically, because the lower end of the heat exchange t...

A heat exchange tube device having a length compensation function is disclosed. The device is used in a catalyst bed layer and comprises a heat exchange tube and a sleeve disposed in the catalyst bed layer. The sleeve comprises an accommodating cavity into which the heat exchange tube penetrates. As the heat exchange tube is mounted in the catalyst bed layer and the periphery and the bottom of the exchange tube are filled with catalyst particles, when the temperature of the catalyst bed layer changes violently, thermal expansion and contraction of the heat exchange tube at the length direction are obvious because the heat exchange tube is long, a length change is large, and the length change may cause destroy of the heat exchange tube. The device can achieve free stretching and contraction at the length direction of the heat exchange tube during the thermal expansion and contraction, thus protecting the heat exchange tube from being destroyed.
Description
technical field [0001] The invention relates to a heat exchange tube device with a length compensation function, specifically a heat exchange tube device capable of compensating for changes in the length direction of the heat exchange tube due to thermal expansion and contraction, and is mainly used in petrochemical, coal chemical, and synthetic Sulfur recovery isothermal reaction equipment in industrial and other fields. Background technique [0002] Extensive mining, processing and use of coal, oil, natural gas and ores, and SO produced during coal combustion 2 The sour water, acid gas and sulfur-containing flue gas produced in the oil refining and steelmaking process will produce a large amount of sulfide, and the direct discharge of these sulfide will cause serious environmental pollution. As the country's requirements for environmental protection become more and more stringent, the technology of desulfurization and sulfur recovery of industrial gases and chemical waste...
