Abstract

The invention discloses a condensation water hammer supression device provided with a disturbed flow bulge structure. The condensation water hammer supression device is mounted at the rear of a steaminlet pipeline and comprises a vertical pipeline, an elbow pipe and a horizontal straight pipe, wherein the vertical pipeline communicates with the elbow pipe through welding; the elbow pipe is connected with the horizontal straight pipe through a flange; the condensation water hammer supression device is characterized in that at least five disturbed flow bulges are arranged on the inner wall of the horizontal straight pipe at intervals in the length direction of the horizontal straight pipe; the disturbed flow bulge in the middlemost position is the highest; and from the middlemost position to two ends, the heights of the disturbed flow bulges are sequentially decreased. When steam passes through the horizontal straight pipe and when steam bubbles pass through the disturbed flow bulges ofdifferent heights, the flow patterns of the steam bubbles change, and the shrinkage speed is reduced to realize the purpose of weakening the strength of a water hammer. The condensation water hammersupression device does not have special shapes in disturbed flow bulges, is simple in processing manner and high in speed reduction effect of the condensation water hammer, does not affect the pipeline strength, and is suitable for suprssion of the condensation water hammer with different flows and at different positions.

Description

technical field [0001] The invention relates to the technical field of fluid pipelines, in particular to a condensate hammer suppression device with a flow-disturbing protrusion structure. Background technique [0002] Vapor-liquid direct contact condensation is widely used in various industrial fields due to its high-efficiency heat and mass transfer characteristics, such as nuclear reactors and waste heat removal systems of ships. However, the direct contact between vapor and liquid may cause serious condensation water hammer phenomenon. Huge pressure fluctuations caused by condensate hammer will seriously impact and damage pipelines and related equipment, affecting the safe operation of the system. Therefore, it is of great significance to study the formation process of condensate hammer and the pressure fluctuation caused by it for the safe operation of equipment. [0003] As we all know, the cause of condensation water hammer is that the bubble edge collides with the ...
