Problems solved by technology

[0011] Aiming at the problem that the existing rotary membrane deaerator cannot deoxygenate the feed water with large flow rate and fast flow rate, the invention develops a water-spraying disc type rotary film deaerator, which is suitable for large flow rate and fast flow rate water. Feed water can also be deaerated, and by adding a collision link in the deaeration process, the deaeration efficiency is improved

Embodiment Construction

[0032] In order to better understand the present invention, the implementation manner of the present invention will be explained in detail below in conjunction with the accompanying drawings.

[0033] Figure 1 to Figure 3 It is an embodiment of the present invention. As shown in the figure, the water-spraying disc-type spinner deaerator includes a water tank 1 and a deaerator head 2. The deaerator head 2 includes a shell 21, a spinner set 23, a shower The water grate 25 is provided with a water spray tray 24 below the water spray grate 25, and the water spray tray 24 includes a multi-layer water spray plate 241, and two adjacent layers of water spray plates 241 are arranged crosswise, and the water spray plate 241 is connected to the shell 21. By setting the water spray tray 24, the deaerator can deoxygenate the feed water with large flow rate and fast flow rate. During the 24 process, it collides with the water spray plate 241 many times, so that the feed water is fully con...

Abstract

The invention discloses a water spraying tray type rotating-film deaerator, comprising a water tank and a deaeration tower head, wherein the deaeration tower head comprises a shell, a rotating film group and a water spraying strainer; a water spraying tray is arranged below the water spraying strainer; the water spraying tray comprises multiple layers of water spraying plates; every two adjacent layers of water spraying plates are arranged in a crossed way; and the water spraying plates are connected with the shell. According to the invention, the deaerator can realize deaeration of feed waterwith large flow and fast flow speed in virtue of the water spraying tray; the feed water passes through each layer of the water spraying tray in sequence and does not cause deformation of the water spraying tray; and the feed water collides with the water spraying plates a plurality of times when passing through the water spraying tray, so the feed water fully contacts with secondary steam and isoverally and rapidly heated to a saturation temperature, so the purpose of deep deaeration is achieved, and deaeration efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water supply deaerator equipment, in particular to a water-spraying disc type spin film deaerator. Background technique [0002] In order to prevent corrosion of thermal equipment and its pipelines, dissolved oxygen and other gases dissolved in boiler feed water must be removed. To ensure the safe operation and long service life of thermal equipment. The principle of thermal oxygen removal is Henry's law and Dalton's law. For various gases dissolved in water, under a certain pressure, the higher the temperature of the water, the lower the solubility. Thermal deoxygenation is to use steam to heat the feed water to the saturation temperature under the corresponding pressure, the partial pressure of the steam will be close to the full pressure on the water surface, and the partial pressure of various gases dissolved in water will be close to zero, so the water will not have The ability to dissolve gas, the...
