[0048] The water storage component 10 is also provided with a nitrogen pipeline 20, a water film regulating mechanism 40, and an exhaust mechanism 50;

[0049] The nitrogen pipeline 20 includes a venturi tube 203 , one end of which is connected to a nitrogen inlet pipe 206 , and the other end of which is provided with a water film regulating mechanism 40 ;

[0050] The water film adjustment mechanism 40 includes a three-way flange valve 401, an adjustment box 402 is installed on the three-way flange valve 401, an adjustment screw 404 is installed in the adjustment box 402, and the adjustment screw 404 is connected to a movable plug 403 via a thread. The movable plug 403 is provided with a conical head 403b, and an adjustment ring 401e is provided below the conical head 403b. The adjustment ring 401e is provided with a chamfer adapted to the conical head 403b. The three-way flange valve 401 is also connected to a water film forming head 410;

[0051] The exhaust mechanism 50 includes an exhaust flange pipe 501, in which a lower exhaust plate 502 and an upper exhaust plate 507 are provided. The lower exhaust plate 502 can be rotatably mounted in the exhaust flange pipe 501, and the upper exhaust plate 507 can be rotatably mounted on a plug 505. The plug 505 is mounted in the exhaust flange pipe 501 through a moving pair, and the plug 505 is also connected to the cylinder 511 through a connecting shaft 504.

[0052] In the present invention, a nitrogen pipeline is provided, and a Venturi tube, a circulating water pipe, and a nitrogen displacement pipe are provided on the nitrogen pipeline. When nitrogen is introduced into the nitrogen inlet, a Venturi effect can be formed at the Venturi tube. On the one hand, the water stored in the water storage tank can be repeatedly sucked into the water film to repeatedly form a water film. By introducing steam, the water film circulates and fully contacts with the steam, thereby realizing cyclic heating and deoxygenation. On the other hand, nitrogen can be filled into the water stored in the water storage tank to squeeze the oxygen dissolved in the water, occupying the dissolution space and thereby displacing it.

[0053] A water film adjustment mechanism is provided to observe the size of the water film pressure gauge and accurately adjust the size of the water film. When the optimal value is reached, the water film is fully in contact with the steam and fully heated, thereby reducing the solubility of oxygen in water and achieving deoxygenation.

[0054] In an alternative embodiment, see Figure 1 and 2 As shown in Figure 7, the nitrogen pipeline 20 further includes an air filter 204 and a pressure valve 205.

The cylindrical portion 203b is provided with a nitrogen replacement upper pipe 202.

[0055] It should be noted that when nitrogen is introduced from the nitrogen inlet pipe, the cylindrical part of the venturi tube is the positive pressure port and the throat of the cylinder is the negative pressure port, thereby forming a venturi effect. After the venturi effect is formed, the water in the water storage tank can be sucked to the water film forming head, and the water film is formed in this cycle. At the same time, the nitrogen injected will also pass into the water in the water storage tank from the nitrogen displacement upper pipe, thereby squeezing out the oxygen dissolved in the water.

[0059] It should be noted that an exhaust mechanism is provided. By starting the cylinder, the plug is driven to move as a piston. The piston rises, the lower exhaust plate rotates and opens, and the gas in the water tank is drawn into the exhaust flange pipe. The piston is pressed down, the lower exhaust plate rotates and closes, and the upper exhaust plate rotates and opens to discharge the gas from the exhaust port. The upper and lower exhaust plates are opened alternately, which can effectively remove the gas in the water tank on the one hand, and prevent the mixing of external gas on the other hand.
