Abstract
The present invention discloses an air cooled steam exhauster provided with a built-in oxygen remover. The present invention relates to a steam exhauster. The existing steam exhauster which is matched with an air cooled turbo unit has the defects of the occupation of a great amount of the workshop space of a power plant and poor deoxidization effect. The air cooled steam exhauster provided with a built-in oxygen remover relates to a steam exhauster 1, a condensed water supplementing sparge pipeline 2, a deflector 3 and a deaerator device 4 which is arranged in the steam exhauster 1, wherein the condensed water supplementing sparge pipeline 2 and the deflector 3 are arranged in the steam exhauster 1. The deaerator device 4 comprises a heating steam passage 4-1, an upper sprinkling screen 4-2, a stuffing layer 4-3, a lower sprinkling screen 4-4 and a condensation water pipeline 4-5. The stuffing layer 4-3 is arranged between the upper sprinkling screen 4-2 and the lower sprinkling screen 4-4. A water jet 4-5-1 of the condensation water pipeline 4-5 is arranged above the upper sprinkling screen 4-2, and an air jet 4-1-1 of the heating steam passage 4-1 is arranged below the lower sprinkling screen 4-4. The deaerator device is arranged in the steam exhauster by the present invention, and the present invention saves the space of land occupation, has favourable deoxidization effect, and is good for popularization and application.
Description
Technical field
The present invention relates to a kind of steam exhaust device.
Background technique
Existing air-cooled steam turbine generator group supporting steam exhaust device, its water of condensation deaerating plant all independently is arranged in outside the steam exhaust device, not only taken a large amount of power plant factory building spaces, and deaerating effect is also bad.
Summary of the invention
Be arranged in existing taking outside the steam exhaust device at existing deaerating plant than large space and the bad drawback of deaerating effect, the invention provides a kind of can the saving and take up an area of space and the good air cooling steam exhaust device that has built-in deaerating plant of deaerating effect, it comprises steam exhaust device, in steam exhaust device, be provided with water of condensation moisturizing water pipeline and guide plate, in steam exhaust device, also be provided with deaerating plant, described deaerating plant comprises the heating steam passage, last trickle net, packing layer, following trickle net and condensing water conduit, described packing layer is arranged between trickle net and the following trickle net, the water orifice of condensing water conduit is arranged on the top of trickle net, and the puff prot of heating steam passage is arranged on down the below of trickle net.Water of condensation deaerating plant of the present invention is compared with existing steam exhaust device, has the following advantages: 25 square metres of (calculating) 1, minimizing floor spaces with a 600MW unit, save 150 cubic metres in space; 2, the connecting tube between steam exhaust device and the deaerating plant is cancelled naturally, and system is simple, has also saved material simultaneously; 3, the path of heating steam introducing is reasonable, and the deaerating plant structure is perfect, and deaerating effect is good, and the oxygen content of water of condensation is by reducing to below the 40PPb more than the original 100PPb; 4, through experimental verification, it can be with the Subcoold temperature of water of condensation by original reducing to below 0.5 ℃ more than 7 ℃.Be beneficial to and apply.
