Abstract
The utility model relates to a deoxidization device. The deoxidization device is composed of a deoxidization head outer shell, a spiral film tube, a water spraying tray, a packing layer and the like, wherein supplied water which flows into a water chamber through a water inlet is sprayed into the spiral film tube through the water inlet due to a pressure difference, spirally flows down along the inner wall of the spiral film tube, and forms a rotary water film skirt at the lower end of a tube opening; the water film skirt is fully contacted with steams at an opening of a primary air inlet pipe and is heated to a saturated temperature instantaneously, and uncondensed water is separated out rapidly so as to finish the deoxidization preliminarily; the preliminarily deoxidized water is allocated to the packing layer through the water spraying tray, and the water in the packing layer is separated into a shape of a water film again, so that the surface tension of the water is reduced greatly, and the water has enough time to contact with the steam at an opening of a secondary air intake pipe; and the residual oxygen in the water is further separated out in the packing layer, so that the oxygen removal amount of the discharged water of the deoxidization device reaches to the standard requests.
