Abstract
The utility model discloses a degassing tower for vacuum deoxygenization for a boiler. The degassing tower comprises a degassing tower body, wherein a spraying head is arranged inside the degassing tower body; and a filler layer is arranged on the lower part of the spraying head. The degassing tower has the advantages of simple structure, energy conservation and good deoxygenization effect.
Description
Technical field
The utility model relates to boiler deaeration in condenser auxiliary facility field, relates in particular to a kind of boiler deaeration in condenser degassing tower.
Background technology
Owing to being dissolved with the obnoxious flavour to metallic corrosion in the water, such as oxygen, carbonic acid gas, cause the metallic surface heavy corrosion of boiler, pipe network and various auxiliary facilitys, shortened boiler work-ing life.Therefore, countries in the world all take much count of oxygen removal of boiler feedwater.China recent years boiler quantity growth is very fast, particularly hot water boiler quantity increases a lot, just used thermal deoxygenizing apparatus at some large-sized boilers, many medium small boilers do not have deoxygenation because of feedwater, go into operation and move 5～7 years, even the phenomenon of scrapping with regard to producing boiler inside heated surface corrosion in 2～3 years, the spraying degasification in the medium small boiler vacuum, mostly adopted, be that the water atomisation is increased water, vapour contact surface area, be beneficial to oxygen and from water, overflow.But in fact, often can not obtain good deaerating effect, this is because small water droplet has very large surface tension, dissolved gases be not easy by water droplet surface diffusion out, the surface tension of water raises with temperature and reduces, the working temperature of deaeration in condenser is between 30～60 ℃, obviously, because the relation of surface tension and temperature makes deaeration in condenser can not obtain good deaerating effect, has limited the performance of deaeration in condenser power savings advantages.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, energy-conservation, boiler vacuum deaerating plant that deaerating effect is good is provided.
The utility model is achieved by the following technical solution: boiler deaeration in condenser degassing tower, comprise the degassing tower body, and described degassing tower body interior is provided with fog-spray nozzle, and the bottom of described fog-spray nozzle is provided with packing layer.
Described packing layer is that the Stainless Steel Helices layer of some shapes consists of.
The position of degassing tower body 4/5 height that described fog-spray nozzle is positioned at.
The utility model boiler deaeration in condenser degassing tower adopts the successively deoxygenation of spraying filler, and oxygen-containing water flows to packing layer after the fog-spray nozzle atomisation reaches preliminary deoxygenation, make water form moisture film at packing layer, contacts again deoxygenation with the gas that rises; And filler is the larger Stainless Steel Helices of specific surface, so that deoxygenation is better.
The utility model boiler deaeration in condenser with degassing tower compared with prior art has characteristics simple in structure, energy-conservation, that deaerating effect is good.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Sequence number among the figure: 1, degassing tower body; 2, fog-spray nozzle; 3, packing layer; 4, the Stainless Steel Helices of shape.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
According to shown in Figure 1, a kind of boiler deaeration in condenser degassing tower comprises degassing tower body 1, and described degassing tower body 1 inside is provided with fog-spray nozzle 2, and the bottom of described fog-spray nozzle 2 is provided with packing layer 3; The Stainless Steel Helices 4 that described packing layer 3 is some shapes consists of; The position of degassing tower body 1 4/5 height that described fog-spray nozzle 2 is positioned at.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not consist of the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model above scheme being done that does not break away from technical solutions of the utility model all still belongs within the utility model protection domain.
