Air cooled steam exhaustor with built-in oxygen remover

Abstract

The invention includes a exhaust device, a sparge pipeline, a deflector and a deaerator set in the exhaust device. The deaerator comprises a heating steam passage, a upper sprinkling screen, a lower sprinkling screen, a stuffing layer disposed between the upper sprinkling screen and the lower sprinkling screen and a condensation water pipeline. The water jet of the condensation water pipeline is set above the upper sprinkling screen. The air jet of the heating steam passage is set below the lower sprinkling screen.

Description

technical field

[0001] The invention relates to a steam exhaust device. Background technique

[0002] In the existing steam exhaust device for air-cooled turbo-generator set, the condensed water deoxygenation device is independently arranged outside the exhaust device, which not only occupies a large amount of power plant workshop space, but also has poor oxygen removal effect. Contents of the invention

[0003] Aiming at the disadvantages of the existing oxygen removal device being arranged outside the steam exhaust device, which takes up a large space and has a poor oxygen removal effect, the present invention provides a built-in oxygen removal device that can save space and have a good oxygen removal effect. An air-cooled steam exhaust device for an oxygen plant, which includes a steam exhaust device, in which a condensed water replenishment water spray pipe and a deflector are arranged, and a deoxygenation device is also provided in the steam exhaust device, and the de...
