Description

Technical Field

[0001] The utility model relates to a circulating fluidized bed boiler drum, in particular to a wall hanging connection mechanism of a steam-water separator in the drum. Background Art

[0002] After the saturated water vapor generated in the circulating fluidized bed boiler enters the drum, it first enters the steam-water separator for separation. The steam-water separator mainly relies on centrifugal action to separate steam and water. The steam-water separator can not only eliminate the kinetic energy of the steam-water mixture, but also make full use of its kinetic energy for separation; the layout of the steam-water separator is reasonable, which plays a role in uniform steam flow and improving separation effect to a certain extent; the layout factors of the existing steam-water separator include: the depth of immersion in the boiler water, the distance between the steam-water separators, the distance between the steam-water separator and the center line of the drum, and the drainage speed, etc. When the steam-water separator in the drum is reasonably determined to be arranged, the steam-water separator needs to be safely and firmly fixed in the middle of the drum; but there are many components inside the drum, and the steam-water separator has a cleaning orifice plate on the top, a sewage pipe, a grid plate, etc., and a baffle and a guide plate on the side; therefore, how to fix the steam-water separator on the drum wall and facilitate adjustment and maintenance has become a problem that needs to be solved on site. Summary of the invention

[0003] The utility model provides a wall-hanging connection mechanism for a steam-water separator in a boiler drum, which solves the technical problem of how to conveniently fix and adjust the steam-water separator.
