Abstract
The invention relates to the technical field of thermal deaerating devices, in particular to a thermal deaerator. The thermal deaerator comprises a deaerator shell, wherein a deaerating water tank is connected to the bottom of the shell, a steam distributor is arranged on the lower portion of the shell and connected with a steam pipe to reach the exterior of the shell, a packing layer is further arranged in the shell, a water inflow pipe is arranged on the side wall of the upper portion of the shell and leads to the interior of the shell, a plurality of spraying nozzles are arranged on the water inflow pipe, an exhaust pipe is arranged on the top of the shell, and a conical baffle is arranged below the exhaust pipe. The thermal deaerator is stable and reliable in deaerating effect, and the content of salt in water is not increased after deaeration is performed.
Description
Technical field
The present invention relates to thermal deoxygenizing apparatus technical field, be specifically related to a kind of atmosphere-type thermodynamic oxygen remover.
Background technology
Often aerobic is dissolved in boiler feedwater, nitrogen, the gases such as carbon dioxide, the wherein existence of carbon dioxide and oxygen, boiler is just easy to corrode, especially oxygen, he is very active gas, can with a lot of nonmetal direct chemical combination, when after itself and nonmetal or metal compound, often form stable oxide, or produce precipitation, corrosiveness is risen to boiler, deoxygenation need be carried out to boiler feedwater, thermal de-aeration is exactly in water, introduce the steam with certain pressure, by water by heat to fluidized state, the oxygen dissolved in such water will overflow from water because solubility diminishes, again the oxygen of spilling is discharged together with a small amount of steam do not condensed, thus guarantee feed-water quality, wherein, temperature controls to occupy sizable ratio in process of production, so temperature controls extremely important.
Summary of the invention
The object of this invention is to provide the thermal deaerator that a kind of deaerating effect is reliable and stable.
The object of the invention is to be achieved through the following technical solutions: a kind of thermal deaerator, comprise deaerator shell, it is characterized in that: described housing bottom is connected with deoxygenation water tank, described lower housing portion is provided with steam distributor, described steam distributor is connected with steam pipe to outside housing, also packing layer is provided with in described housing, described housing upper sidewall is provided with water inlet pipe, described water inlet pipe leads to enclosure interior, described water inlet pipe is provided with some nozzles, described case top is provided with blast pipe, and described blast pipe has circular cone baffle plate.
Spiral auxiliary heating pipe is also provided with in described deoxygenation water tank.
Described deoxygenation water tank is also provided with sensor interface, passes into described deoxygenation water tank inner.
Operation principle of the present invention is: oxygenated water enters from deaerator shell top water inlet pipe, by nozzle, water is become vaporific downward sprinkling, vaporific water drops on packing layer, then deoxygenation water tank is dropped down onto through packing layer, steam is sprayed by steam distributor, first fully contact with the water sprayed from nozzle in packing layer, and heat deoxygenation, then continue to rise, contact with nozzle spray water out and heat deoxygenation, oxygen in heating process enters air through blast pipe with residual steam simultaneously, and deaerated water then flows into water tank boiler of feeding and uses.Described packing layer is made up of porcelain ring, can increase the contact area of water and steam.
Have employed technique scheme, a kind of thermal deaerator of the present invention can not only except the oxygen in anhydrating, and can except the carbon dioxide in anhydrating and oxygen, and deaerating effect is reliable and stable, does not increase salt content after deoxygenation in water.Deoxygenation water tank is also provided with sensor interface, passes into described deoxygenation water tank inner, can respond to the temperature in deoxygenation water tank in real time, to control the temperature in deoxygenation water tank in time, improve operating efficiency.
