Water deoxygen device

The utility model relates to a boiler water deoxygenizing device, and belongs to the technical field of the energy source device. The device comprises a seal tank, a water inlet valve which is connected with the water inlet of the seal tank, a water outlet pump which is connected with the water outlet of the seal tank, a blowdown valve which is connected with the blowdown opening of the bottom of the seal tank, a magnetic valve which is connected with the exhaust outlet of the top part of the seal tank, an air water separating valve which is connected with the magnetic valve, and a vacuum meter which is connected with the upper part of the seal tank. The intake valve and the water outlet pump are respectively connected with a boiler water supplying pipeline. The boiler water enters into the device through the water inlet valve, and flows out from the water outlet pump to supply the boiler after deoxidation. The desorption gas flows out of the seal tank through the magnetic valve and the air water separating valve. The vacuum meter monitors the operating state. The water deoxygenizing device of the utility model causes the oxygen content in the water to be smaller than 0. 1mg/L when the boiler water is in stable operating condition, and effectively solves the oxygen corrosion problem.
