The condensate water with too high oxygen content will cause oxygen corrosion to the pipelines of the equipment, thereby reducing the reliability and service life of the equipment and affecting the safe operation of the equipment.

[0037] The above are only preferred embodiments of the present utility model, and do not limit the implementation manners and protection scope of the present utility model accordingly.

[0038] The present utility model further has the following implementation manners on the above basis:

[0039] In a further embodiment of the present utility model, the bubbling pipe 7 is preferably a bubbling pipe made of high-temperature resistant stainless steel.

[0040] In a further embodiment of the present utility model, the inside of the bubbling pipe 7 is subjected to an antioxidant treatment to prevent the bubbling pipe 7 from being oxidized during operation.

[0041] In a further embodiment of the present utility model, a valve is provided at the bottom of the drain pipe 8 and / or the drain hole 6, and the valve is used to control the height of the condensate water at the bottom of the container 2.

[0042] Specific operation steps of the condensate water tank with a vacuum deaeration function of the present utility model:

[0043] Taking the condensation work as an example, first, close the manhole door 1 to make the whole container 2 in a sealed state. The exhaust steam generating device supplies exhaust steam to the inner cavity through the interface pipe 3. At the same time, the condensate flows into the straight pipe 51 through the liquid inlet pipe 5, and the condensate in the straight pipe 51 is atomized through the nozzle 52 and sprayed into the inner cavity of the container 2. After the atomized condensate contacts the exhaust steam, the atomized water is heated by the exhaust steam and thus oxygen is precipitated.

[0044] When there is a situation where the contact between the exhaust steam and the atomized condensate is incomplete, a part of the unheated condensate accumulates at the bottom of the inner cavity by gravity. At this time, the steam generating device supplies hot steam to the bubbling pipe 7, and the hot steam is evenly ejected through the air holes on the bubbling pipe 7 to heat the condensate accumulated at the bottom of the container 2, so that the condensate at the bottom is heated and oxygen is precipitated. When the heating work is completed, the vacuum pump extracts the oxygen and other non-condensable gases precipitated in the container through the vacuum pipe 4 to complete the deaeration operation of the condensate.

[0045] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be able to realize that the solutions obtained by equivalent substitution and obvious changes made by using the description and illustrated content of the present invention should be included in the protection scope of the present invention.
