I. Introduction The domestic power plants commonly used in conventional deaerator head with oxygen, which has a rotating film type, spray filler type, water spray disc, etc; Mounting of vertical deaerator head and horizontal oxygen first two. Oxygen in the oxygen scavenging process is completed in the head, including the rotary film segment (sprayed layer) initial oxygen, most of the gas in the water can be removed in the following filler layer or the depth of the water spray disk oxygen, out of the water residual gas. With the continuous development of oxygen technology, built-headless deaerator its unique advantages began to occupy a certain market share. Its technical characteristics are: a price lower than conventional equipment, machine has a head deaerator; b save construction costs, reduced height between oxygen 3 to 4 m; c low exhaust loss .... . d load range is between 10% to 110%, can ensure water oxygen content less than 7μg / L;. e single container structure, system design is simple, optimization, avoid stress cracks, reliable seismic performance; f. quality light, low vibration operation;. g spin film optimized design, or constant speed nozzles, safe and reliable no moving parts, maintenance-free performance;. h diameter and interface design flexibility, ease of transportation and installation layout. Second, the structure that I plant design and manufacture of the new tower deaerator water atomization method based on optimized spin membrane and into the overall constant speed nozzle types. Specific works as follows: deaerator steam condensate into space from the constant speed of the nozzle, initial oxygen, and then fall into the water flow to the outlet space; heated steam discharge tube axially along the cylinder deaerator uniform arrangement of the heating steam through the discharge tube into the underwater deaerator, hybrid heating and water, while the water flow disturbance, and dissolved oxygen in water and other non-condensable gases from the water to the surface, to reach the depth of condensate purpose of oxygen . The longer the water flow in the deaerator, the depth of the oxygen in the water the better. Steam is fed from underwater, not condensed heating steam (in this case, the saturated steam) to bring non-condensable gases to escape the water, the flow of the exhaust nozzle area (around the exhaust nozzle area is not saturated water film (fog) area) not condense in the exhaust area of ??the heating steam condenses into water, non-condensing gases discharged from the exhaust port. Non-condensing gas flowing exhaust port flow, the water volume in certain circumstances, oxygen cylinder diameter is larger vapor space of the smaller non-condensing gas partial pressure, so that we can effectively control the non-condensable gases in liquid diffusion, to avoid the occurrence of secondary dissolved oxygen. Therefore, using a large diameter cylinder deaerator better. The new tower is mainly composed of oxygen to the tank structure, inside a steam separation device butterfly constant speed nozzles, steam separator unit, throttle spray steam pipes, water antivortexing devices and other components. This type deaerator compact structure, rapid heating, good oxygen effect. 2 sets of spray steam pipes were acting on the surface and underwater, water spray steam pipe is installed above a large orifice nozzles, corresponding with the upper rotary membrane tube, so that the direct effect and spin-membrane water vapor skirt; laterally opened a purge port, so that the surface of a certain wind force, the residual gas will remain in the oxygen on the water outlet tank. Another way the steam main pipe from the lower inlet changed into the same throttling technology to ensure maximum supply temperature inside the tank, so that even underwater jet vapor, water vapor to form a dynamic disordered state of oxygen sufficient.
