Description

Technical Field

[0001] The utility model belongs to the technical field of steam-water separation equipment, in particular to an external steam-water separator for a steam generator. Background Art

[0002] The steam generator is one of the key main equipment of a pressurized water reactor nuclear power plant. It is the pressure boundary between the primary and secondary sides. It is used to transfer the heat of the reactor coolant on the primary side to the secondary side through the heat transfer tube, and heat the water on the secondary side into saturated steam. The wet steam passes through the steam-water separator body and the dryer for steam-water separation. After separation, the qualified steam drives the steam turbine to generate power. The steam-water separator is an important component of the steam generator body. The wet steam generated by the steam generator tube bundle passes through the steam-water separator for primary separation to remove most of the water in the wet steam. The steam coming out of the steam-water separator enters the dryer for further separation. The main function of the steam-water separator is to reduce the humidity of the steam at the dryer inlet, creating conditions for the steam generator to produce evenly heated steam.

[0003] According to a steam-water separator for a steam generator disclosed (Publication No.: CN 218599698 U), including a steam-water separator body and an air inlet pipe and an air outlet pipe respectively arranged on the two side walls of the steam-water separator body, the lower end of the steam-water separator body is provided with a water outlet pipe, and the inner cavity of the steam-water separator body is provided with a separation shell.

The above application has the effect of effectively separating the steam containing water, and at the same time expands the time and stroke of steam drying, and can better collect the water in the steam evenly, and has the effect of simple operation and convenient use. However, the above application cannot effectively connect the steam-water separator with the steam generator, which is easy to cause steam leakage and scalds to the staff, and the steam-water separation effect is not good, and the practicality is not strong.
