The invention relates to the technical field of energy-saving and environment-friendly equipment, in particular to a deaerator dead steam recovery device. The deaerator dead steam recovery device comprises a normal pressure tank, a cooling working medium atomizing pipeline and a recycling pipeline, wherein one or more deaerators are connected with the normal pressure tank, and the deaerators convey discharged oxygen, carbon dioxide waste gas and dead steam to the normal pressure tank; the cooling working medium atomizing pipeline is in communication with the normal pressure tank and provides acooling and atomizing working medium for the normal pressure tank, and the cooling and atomizing working medium is in contact with oxygen, carbon dioxide waste gas and dead steam in the normal pressure tank for cooling, so that the dead steam is liquefied; and the recycling pipeline is arranged at the bottom of the normal pressure tank. The deaerator dead steam recovery device has the beneficialeffects that high-quality steam does not need to be consumed when the dead steam is recycled, and the process is simple and easy to operate; stable operation of the deaerator is not influenced in thedead steam recovery process; noise pollution and heat pollution caused by waste gas emission of the deaerator are eliminated, and the surrounding operation environment is improved; and the deaerator dead steam recovery device is simple in structure, high in heat transfer efficiency, capable of simultaneously recovering dead steam of multiple deaerators and wide in application range.
Description
technical field [0001] The invention relates to the technical field of energy-saving and environmental protection equipment, in particular to a device for recovering exhaust gas from a deaerator. Background technique [0002] In industrial production, the deaeration method of boiler feed water is usually the way of thermal deaeration. The thermal deaerator method has the advantages of simplicity, reliability and stable deoxygenation effect and is widely used. However, the thermal deaerator is accompanied by steam discharge during the exhaust gas discharge process, and the exhaust gas discharged from the deaerator has residual pressure. The noise generated can reach more than 85dB(A), causing environmental noise pollution. The exhaust steam in the exhaust gas has high latent heat. If it is not recycled, it will cause environmental heat pollution and heat energy loss, and also cause water loss. In winter, these water vapor will be on the ground. Condensation and freezing dete...
