Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of heat engineering more particularly, it is a kind of oxygen-removing water tank bubbling generating device. BACKGROUND

[0002] The heat oxygen-removing water tank is a new type of oxygen-removing device, which can remove dissolved oxygen and other gases in the feedwater of a thermal system, prevent corrosion of thermal equipment, and is an important device for ensuring safe operation of power plants and industrial boilers.

[0003] In the container, the amount of gas dissolved in water is proportional to the partial pressure of gas above the water surface. The main method of thermal deoxygenation is to use steam to heat the feedwater, increasing the water temperature and gradually increasing the partial pressure of steam above the water surface, while gradually reducing the partial pressure of dissolved gas. The dissolved gas in the water continuously escapes, and when the water is heated to the boiling temperature at the corresponding pressure, the water surface is full of water vapor, and the partial pressure of dissolved gas is zero. The water no longer has the ability to dissolve gas, i.e. the dissolved gas, including oxygen, can be removed. The effect of deoxygenation depends on whether the feedwater is heated to the boiling temperature at the corresponding pressure, and on the rate of removal of dissolved gas, which is greatly influenced by the size of the water and steam contact surface.

[0022] The first embodiment of the utility model is as follows:

[0023] The application discloses a kind of oxygen removal water tank bubble generating device, including tank 1, cavity is provided in tank 1, tank 1 is provided with baffle 13, cavity is divided into preheating section and degassing section by baffle 13, in preheating section, condensate water and steam are contacted sufficiently to exchange heat, so that condensate water is warmed to realize preheating, in degassing section, condensate water has been sufficiently warmed, is affected by temperature rise and bubble, realizes sufficient degassing.

[0024] Preheating section upper portion is provided with degasser 4, degasser 4 includes cylindrical side wall, side wall is installed in the upper portion of tank 1 by support 9, the inside of side wall is provided with horizontal direction flat plate type spray shroud 8, spray shroud 8 is provided with a plurality of through holes for liquid and gas to pass through, spray head 6 sprays condensate water towards spray shroud, the lower end of condensate water pipe 7 extends to the inside of tank 1 and is connected with spray head 6, spray head 6 is spring type spray head 6, condensate water enters condensate water pipe 7 to make its internal pressure rise, so as to press spring to make the lower portion of spring type spray head 6 open, condensate water is sprayed from here, at this time, steam rises upwards, steam and condensate water droplets are contacted sufficiently to realize sufficient heat exchange, gas and part of steam are discharged from exhaust port 5, the inside of exhaust port 5 is provided with detachable disc, the middle portion of disc is provided with exhaust hole 14, by replacing disc with different diameter exhaust hole 14, discharge efficiency can be changed, when the diameter of exhaust hole 14 is larger, more condensable gas is discharged, but at the same time, more steam escapes, when the diameter of exhaust hole 14 is smaller, less steam escapes, but less condensable gas is discharged.

[0025] Tank 1 upper end is provided with steam main pipe 3, steam main pipe 3 extends to the lower portion of tank 1 and is connected with bubble assembly, bubble assembly includes steam branch pipe 16 arranged at the lower end of steam main pipe 3, steam branch pipe 16 extends along horizontal direction, the lower end of baffle 13 is connected with the middle portion of steam branch pipe 16, the two sides of steam branch pipe 16 are both connected with a plurality of bubble pipes 15, bubble pipe 15 is provided with a plurality of air holes 14, all air holes 14 are arranged towards directly below, not only bubble generation is more sufficient, but also condensate water will not enter steam branch pipe 16 under the influence of air pressure.

[0026] In one aspect, the steam can be introduced to exchange heat with the condensed water to increase the temperature of the condensed water, to preheat the condensed water before being discharged into the boiler, and to reduce the solubility of the condensable gas in the water, so that the oxygen and carbon dioxide content is reduced to within the standard, and the PH is prevented from being too high to corrode the boiler. In another aspect, the oxygen in the water can be efficiently removed by the introduction and rupture of the bubbles. When the device is working, the bubbles are first injected into the water body through the air holes 14. During the rising of the bubbles in the water, the oxygen molecules around the bubbles are captured and adsorbed. As the bubbles continue to rise and shrink, the oxygen is gradually compressed and absorbed into the bubbles. When the bubbles eventually rupture, the oxygen inside the bubbles is released to the degassing device 4, and then discharged from the exhaust port 5.

However, at the end of the bubbling pipe 15, the bubbling is reduced due to the reduced air pressure, so that the temperature rise and oxygen removal are not uniform and sufficient. The pressure compensation pipe 12 is arranged to make the pressure at both ends of the bubbling pipe 15 the same, so that the bubbling is more sufficient and uniform, and the temperature rise effect and the bubbling oxygen removal effect are improved.

[0028] The lower part of the box body 1 is provided with a water outlet pipe 10, and the condensed water that has reached the standard after oxygen removal is discharged from the water outlet pipe 10 and enters the boiler.

[0029] The upper part of the box body 1 is provided with a pressure relief safety valve 2. Although the pressure in the box body 1 is not high, there is still a risk. The pressure relief safety valve 2 is arranged to ensure the safety of the box body 1.
