Description

Technical Field

[0001] The utility model relates to the technical field of steam condensation heat exchange pipelines, and specifically relates to a steam condensation heat exchange pipeline structure. Background Art

[0002] Steam condensation heat exchange pipe is a device used for heat exchange between steam and pipes, equipment or other media. Its function is to transfer the heat released by steam to the medium that needs to be heated, and at the same time convert steam into condensed water. This kind of pipe is usually made of metal materials, such as carbon steel, stainless steel, etc. In the process of steam condensation heat exchange, steam comes into contact with pipes, equipment or other media, releases heat and condenses into condensed water. This heat exchange process can improve the utilization efficiency of thermal energy and reduce energy waste.

[0003] However, during use, steam will turn into condensed water, and impurities and dirt in the condensed water may be deposited in the pipeline, causing pipeline blockage. This will affect the circulation and heat exchange effect of steam. When condensed water stays in the pipeline for a long time, it is easy to deposit and cause pipeline blockage. This will not only affect the circulation of steam, but also may cause safety problems. Therefore, we propose a steam condensation heat exchange pipeline structure. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: when using a steam condensation heat exchange pipeline, a detachable filtering structure is arranged inside the pipeline, and some impurities present in the steam are filtered through the filtering structure. At the same time, the utility model has a disassembly function, which is convenient for maintenance and replacement during inspection and repair. The impurities in the steam can be effectively filtered to ensure the quality and purity of the steam, and to avoid the adverse effects of impurities on the heat exchange effect. The detachable design makes inspection and maintenance more convenient. When replacement is required, it can be easily disassembled and replaced. At the same time, a liquid storage structure is arranged at the bottom of the end of the pipeline. Condensate is usually formed at the end of the pipeline. This is because when the steam flows in the pipeline, it will gradually cool and condense into water. The condensate is stored and has a discharge function.

[0020] Working principle: When installing the heat exchange pipe 1, flanges are set on both sides of the heat exchange pipe 1, which are respectively connected to the equipment by flanges to keep them fixed. A side pipe 3 is set near the end of the heat exchange pipe 1, and a liquid storage structure 4 is installed at the bottom of the side pipe 3. When the heat exchange pipe 1 is working, the internal steam circulates, and condensed water is usually formed at the end of the pipe. This is because when the steam flows in the pipe, it will gradually cool and condense into water. At the end of the heat exchange pipe 1, the steam has cooled to a sufficiently low temperature to form condensed water, and at the same time it is filtered and blocked by the filter structure 2. The filter is filtered through the through-hole plate 25 in the filter structure 2, so that some impurities in the steam can be filtered. At the same time, the filter structure 2 has a disassembly function, which is convenient for maintenance and replacement during inspection. The through-hole plate 25 is connected with the screw 22 through the sleeve block 23 set on the top. The screw 22 is fixed to the inner wall of the heat exchange pipe 1 through the inner block 21. When the sleeve block 23 is sleeved, one side of the screw 22 is rotated to thread the screw block 24, and the sleeve block 23 is clamped between the inner block 21 and the screw block 24 for fastening. At the same time, the filtering structure 2 is arranged at the top of the side pipe 3. During the filtering process, condensed water will also be formed on the surface of the through-hole plate 25. When a certain weight is accumulated, it will drip into the side pipe 3 and enter the liquid storage structure 4 through the side pipe 3. The liquid storage structure 4 is flange-connected to the side pipe 3 through the connecting pipe 41, and a liquid storage tank 43 is connected on the other side. The condensed water is stored in the liquid storage tank 43. The connecting pipe 41 is controlled by a first valve 42. When a certain amount of condensed water is stored in the liquid storage tank 43, it is discharged through a drain pipe 44 arranged on one side. The drain pipe 44 controls the flow switch through a second valve 45 to ensure the normal operation of the heat exchange pipe 1.
