Description

Technical Field

[0001] The utility model relates to the technical field of deaerators, in particular to a deaerator for a boiler heating system. Background Art

[0002] The spin film deaerator is a replacement product of the spray packing deaerator. The principle of the spin film deaerator is that the make-up water is sprayed out in a spiral shape through the film-forming pipe at a certain angle to exchange heat with the heating steam for deaeration. The feed water is heated to the saturation temperature corresponding to the working pressure of the deaerator, removing the oxygen and other gases dissolved in the feed water, and preventing and reducing the corrosion of the boiler feed water pipe, economizer and other auxiliary equipment.

[0003] Chinese patent document CN220038437U discloses a deaerator for efficient heating of boilers, including a deaeration device. The surface of the deaeration device is fixedly connected with a water circulation tank. The surface of the deaeration device is fixedly connected with a cushion table. The surface of the water circulation tank is fixedly connected with a fixator. The surface of the water circulation tank is fixedly connected with a water inlet pipe. The surface of the water circulation tank is fixedly connected with a tail gas input pipe. In the utility model, the circulating water is heated by the boiler tail gas, so that the circulating water works in a high-temperature environment, enabling the inside of the boiler to quickly heat up and reducing energy loss. During operation, the circulating water in the boiler enters the water circulation tank through the water inlet pipe, is deaerated through the deaeration device, and then the tail gas of the boiler heats the circulating water again through the tail gas input pipe. After the heating is completed, it enters the boiler again through the water delivery pipe, enabling the boiler to quickly heat up and the air pressure to rise rapidly. However, this deaeration device directly connects the circulating water to the deaeration device for high-temperature deaeration through steam. However, the contact area between the high-temperature steam and the circulating water is limited, and the water flow rate of the circulating water is too fast, resulting in the deaeration effect not reaching the expected effect.

[0034] Referring to Figure 1-7 , an embodiment provided by the present invention: An oxygen deaerator for a boiler heating system includes an oxygen deaeration component 1, and a filtering component 2 is installed on the oxygen deaeration component 1. The oxygen deaeration component 1 includes an oxygen deaeration tank 11. A bearing tank 12 is installed on the upper surface of the oxygen deaeration tank 11. A water inlet pipe 13 is connected to the upper surface of the bearing tank 12, which is convenient for connecting circulating water into the oxygen deaeration tank 11. A water receiving plate 14 is fixedly connected to the inner wall of the oxygen deaeration tank 11 to collect and uniformly discharge the water introduced into the oxygen deaeration tank 11. A shower head 15 is installed on the lower bottom surface of the water receiving plate 14 to increase the contact area between the circulating water and the steam. A steam main pipe 16 is connected to one side of the oxygen deaeration tank 11 to introduce the deaerated steam into the oxygen deaeration tank 11. One end of the steam main pipe 16 penetrates through the oxygen deaeration tank 11 and extends into its interior. An exhaust pipe 17 is connected to the other side of the oxygen deaeration tank 11 to discharge the excess gas in the oxygen deaeration tank 11. A drain pipe 18 is connected to the lower bottom surface of the oxygen deaeration tank 11 to discharge the excess circulating water. The oxygen deaeration tank 11 is fixedly connected to a base 19, and there are two groups of bases 19 and they are installed at both ends of the oxygen deaeration tank 11.

[0035] The inner surface of the deaeration tank 11 is fixedly connected with a dispersion plate 111, which collides with the circulating water to increase the dispersion efficiency. A plurality of through holes 112 are formed in the dispersion plate 111 to facilitate the flow of the circulating water. The dispersion plate 111 is arranged directly below the water receiving plate 14. Threaded grooves 141 are formed in the water receiving plate 14, and threads 151 are formed on the outer surface of the shower head 15.

[0036] Working principle: First, connect the circulating water to the water inlet pipe 13. The circulating water first enters the filtering box body 21 through the water inlet pipe 13, and the impurities in the circulating water are filtered by the two filter screens 24. Then, the filtered circulating water enters the deaeration tank 11 from the bearing tank 12, and then the circulating water is delivered to the water receiving plate 14 and passes through the shower head 15, increasing its contact area with the steam and at the same time the exhaust column 162 releases steam to carry out deaeration operation on the circulating water. The treated circulating water is discharged from the drain pipe 18.
