Length-changing non-condensable gas porous flow stabilizer heat exchanger

Abstract

The invention provides a length-changing non-condensable gas porous flow stabilizer heat exchanger which comprises a shell. Sealing heads are arranged at the two ends of the shell correspondingly. A pipe plate is arranged at the connecting position of each sealing head and the shell. Heat exchange pipes are connected with the pipe plates at the two ends. A gas phase in gas-liquid two-phase flow isinsoluble or indissolvable gas, that is, gas cannot be dissolved in liquid in the heat exchange process. Flow stabilizers used for vibration reduction and noise reduction are arranged in each heat exchange pipe. The corresponding multiple flow stabilizers are arranged in the same heat exchange pipe. In the flowing direction of fluid in the heat exchange pipes, the lengths of the flow stabilizersare gradually decreased to a certain position, and then the lengths of the flow stabilizers are gradually increased from a certain position. According to the length-changing non-condensable gas porousflow stabilizer heat exchanger, through length changing of the flow stabilizers, when gas-liquid two-phase flowing exists in a pipeline, pipeline vibration is weakened to the largest degree, the noise level is reduced, and meanwhile flowing resistance is reduced.

Description

technical field [0001] The invention relates to a shell-and-tube heat exchanger, in particular to a two-phase flow heat exchanger containing non-condensable gas. Background technique [0002] Two-phase flow heat exchange containing non-condensable gas widely exists in heat exchange devices, for example, non-condensable gas is mixed in the heat exchange process, or non-condensable gas is produced due to equipment aging during fluid transportation, and natural gas, for example Condensation of mixed media with different boiling points, air separation, refrigeration of mixed refrigerants, cracking of petroleum or waste plastics, production The main technological process of industries such as material gas production. [0003] The existence of the gas phase in the heat exchange process of the fluid containing non-condensable gas will lead to low heat exchange efficiency, worse heat exchange, unstable fluid flow process, and water hammer phenomenon. When the gas-liquid phase of t...

Problems solved by technology

However, it was found during the operation of this device that the space A formed between the three pipes is relatively small because the pipes are tightly combined, because the space A is formed by the convex arc of the three pipes, so most of the space A The narrow space will prevent the fluid from entering and passing through, resulting in a short circuit of the fluid, which affects the heat exchange of the fluid and cannot play a good role in stabilizing the flow.

Simultaneously because the many tubes of above-mentioned structure are combined together, manufacture difficulty
