Abstract

The invention discloses a multi-stage composite steam dehydration structure and a heat accumulator. The multi-stage composite steam dehydration structure comprises: a first-stage dehydration member having a plurality of layers of densely arranged tube bundles arranged at intervals along a first direction, wherein each layer of densely arranged tube bundles having a plurality of tube bodies arranged side by side; a second-stage dehydration member which is located above the first-stage dehydration member, and is provided with a plurality of corrugated plates which are arranged at intervals in the horizontal direction; a third-stage dehydration member which is located above the second-stage dehydration member, and is composed of a plurality of bent pore plates which are connected with one another, wherein through holes are formed in the bent pore plates. According to the multi-stage composite steam dehydration structure, steam is subjected to three times of water drop filtering through the first-stage dehydration member, the second-stage dehydration member and the third-stage dehydration member, so that the dryness of the steam is improved, and the potential safety hazard of a water hammer phenomenon of the steam is reduced.

Description

technical field [0001] The invention relates to the technical field of waste heat steam utilization, in particular to a multi-stage composite steam dehydration structure and a heat accumulator. Background technique [0002] The domestic conventional horizontal heat accumulator does not have a steam dehydration device at the steam outlet. The heat storage and heat release of the heat accumulator are realized by the pressure change of high-pressure saturated water and saturated steam in the heat accumulator. When the heat is released, the flash steam The steam directly enters the external steam pipe network through the heat release pipe. [0003] The wet saturated steam generated by the heat release of the accumulator, the wet steam with water enters the pipe network, and there is a potential safety hazard of the "water hammer" phenomenon. "Water hammer" is also called water hammer, which is a phenomenon caused by the presence of steam and water in the pipeline, and the speed...
