A wet steam vapor-liquid two-phase separation device

Abstract

The invention discloses a vapor-liquid two-phase separation device for wet steam. A support plate and a liquid baffle are respectively provided. The liquid baffle is located above the support plate. A separation bucket is provided on the bottom surface of the support plate. One end of the air intake pipe passes through the support plate and extends into the separation bucket. The sides of the separation bucket are evenly distributed. There is a flow hole, the bottom of the separation bucket is provided with a liquid outlet pipe, a fixed channel is distributed around the support plate, a spoiler is movably connected in the fixed channel, there are gaps distributed on the outer circumference of the support plate, and the liquid baffle There are diversion openings distributed on the outer circumference of the outer circumference, a conduit is arranged between the diversion opening and the gap, an air collecting hood is arranged on the liquid baffle, and an air outlet pipe is arranged on the top of the air collecting hood. The invention has stable structure, multiple separation, good separation effect and reliable use.

Description

technical field [0001] The invention relates to a wet steam vapor-liquid two-phase separation device. Background technique [0002] Steam is used in many industrial and domestic situations, such as the application of steam turbines, but the steam often contains condensed water, forming wet steam, which causes serious water erosion of the moving blades of the steam turbine, and the existence of wet steam significantly reduces the flow efficiency of the steam turbine And affect the safe and economical operation of the steam turbine. Effectively removing moisture from steam turbine wet steam, preventing or reducing water erosion and moisture loss of moving blades is one of the key technologies to ensure safe, reliable and efficient operation of steam turbines. [0003] In the prior art, the vapor-liquid separator is generally used to separate the wet steam directly. The air flow inside the structure has not been slowed down, and the flow rate is too fast, resulting in poor sep...

Problems solved by technology

[0003] In the prior art, the vapor-liquid separator is generally used to separate the wet steam directly. The air flow inside the structure has not been slowed down, and the flow rate is too fast, resulting in poor separation effect. There is still a certain proportion of liquid in the separated vapor phase. Phase composition requires a post-separation operation, which increases the work intensity and is time-consuming and laborious
