Annular separating device heat exchanger with non-condensable gas

Abstract

The invention provides an annular structure separating device shell-and-tube heat exchanger with non-condensable gas. The heat exchanger comprises a shell body, heads are arranged at the two ends of the shell body correspondingly, a tube plate is arranged on the connection position of each head and the shell body, heat exchange tubes are connected with the tube plates at the two ends, and the gaseous phase in two-phase gas-liquid flow is an insoluble or slightly soluble gas, namely the gas does not dissolve in liquid in the heat exchange process; and separating devices are arranged in each heat exchange tube, each separating device comprises a core body and a shell, the cores are arranged in the shells, each shell is fixedly connected with the inner wall of the corresponding heat exchange tube, each core body comprises a plurality of concentric tubes and fins, and the fins connect adjacent concentric tubes. According to the annular structure separating device shell-and-tube heat exchanger with non-condensable gas, a heat exchanger with separating devices with a novel structure is provided, when two-phase gas-liquid flow exists in a pipeline, compared with the background technology, the heat exchanger further enhances heat transfer, weakens vibration of the pipeline and reduces the noise level.

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, mixed refrigerant refrigeration, petroleum or waste plastic cracking, 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 the two-p...

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 Narrowness will cause the fluid to not enter and pass through, resulting in a short circuit of the fluid, which affects the heat transfer 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
