Abstract

The invention relates to the technical field of industrial production, in particular to a congealed water hammer restraining device and a restraining system. The congealed water hammer restraining device comprises a cylinder body, a first restraining element and a second restraining element. The first restraining element and the second restraining element are arranged at the two ends of the cylinder body correspondingly and used for restraining producing of congealed water hammers in multiple positions under the different steam amount. According to the congealed water hammer restraining device and the restraining system, the technical problem that in the prior art, a certain restraining effect can be achieved only aiming at the congealed water hammer in a certain specific position is relieved.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to a condensation water hammer suppression device and a suppression system. Background technique [0002] Because the vapor-liquid direct contact condensation in the tube has high-efficiency heat and mass transfer characteristics, it is widely used in industrial fields such as energy, chemical industry, nuclear energy and military industry. However, when the steam condenses in the tube, the vapor-liquid two-phase flow in the tube is unstable. With the increase of the fluctuation amplitude of the vapor-liquid phase interface, the steam is enclosed in the supercooled water, forming independent bubbles and condensing rapidly. Due to the large difference in vapor-liquid density, the area where the independent bubbles are located will form a negative pressure or vacuum state. Under the dual effects of pressure difference and condensation, the supercooled water is instantly ...
