Steam-water separation corrugated plate and separation device

Abstract

The invention provides a steam-water separation corrugated plate, comprising two crook-free corrugated plates.Middle corrugated segments of the two crook-free corrugated plates are connected through a connecting plate, straight segments at two ends of a combination of the two crook-free corrugated plates are tightly fixed side by side, and a double-layer hollow plate structure is formed; a drain passage forms in the hollow between the two crook-free corrugated plates, and the double-layer hollow plate structure is provided with a drain port.The invention also provides a corrugated plate steam-water separation device.The corrugated plate steam-water separation device is compact in structure and easy to assemble, special crooked drain channel part is not required any more, a flow field in a passage of the separation device is smoother, and resistance coefficient of the passage of the corrugated plates is reduced; manufacture precision of the corrugated plates is improved, and production cost is reduced; with the long drain passage, effective pass area of a drain channel is enlarged, and the ability of the corrugated plate separation device to drain water is improved; the corrugated plate steam-water separation device is useful in separating water particles in steam / water or air-water mixed medium.

Description

technical field [0001] The invention relates to the technical field of steam-water separation, in particular to a steam-water separation corrugated plate and a separator, which can be applied to liquid droplet separation in steam-water and air-water mixed media. Background technique [0002] During the operation of the nuclear power plant system, the requirements for steam dryness are relatively high. In order to obtain higher-quality steam, the nuclear power plant has installed a steam-water separation dryer at the outlet of the steam generator in the primary circuit, and a steam-water separation reheater (MSR) between the high and low pressure cylinders of the secondary circuit steam turbine system to improve the economy of power generation and reduce The occurrence of hazards such as radioactive radiation risk, water erosion of turbine low-pressure cylinder blades, and salt accumulation in pipeline valves.

AI Technical Summary

Problems solved by technology

[0003] Nuclear power plant evaporator dryers and steam-water separation reheaters currently use single-hook and double-hook structure corrugated separation plates, which have the following problems: 1. The critical flow rate of the separator is low; 2. The separator equipment is bulky and expensive; 3. The separation The efficiency cannot meet the design requirements under the condition of large flow and high humidity; 4. The hook parts need to be processed separately and then welded. The structure is complicated, and it is not easy to process and ensure the manufacturing accuracy of corrugated plates.
