During the discharge process, the turntable and the push plate will rotate, and then collide with the soundboard, causing a sound, which has the effect of an alarm.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, in a specific embodiment, the tower shell 101 and the tower base 1011 are both provided with connecting flanges at the bottom, the tower shell 101 and the tower base 1011 bottom connecting flanges are fitted to each other, and locking bolts are screwed on the connecting flanges, the bottom of the tower base 1011 is fixedly mounted on the deaerator box 201, and an exhaust pipe 1012 is installed on the top of the tower shell 101, and an exhaust valve 1013 is installed on the exhaust pipe 1012. A first steam delivery pipe 105 is provided on the side wall of the tower shell 101, and the first steam delivery pipe 105 is L-shaped, and the outlet direction of the first steam delivery pipe 105 located inside the tower shell 101 is upward, and the first steam delivery pipe 105 is installed between the water film guide cover 103 and the diffusion cover 106, and a second steam delivery pipe 1092 is installed on the side wall of the tower base 1011, and the end of the second steam delivery pipe 1092 is connected to the hollow ring 109, and the hollow ring 109 and the heat storage filler 108 are vertically corresponding.

A vent hole 1031 is opened on the inner wall of the water film guide cover 103, and the vent hole 1031, the through hole in the center of the film rotary body 102 and the exhaust pipe 1012 are all interconnected. The film rotary body 102 and the first steam delivery pipe 105 cooperate with each other to deoxygenate a portion of the treated liquid.

[0046] Embodiment 2:

[0047] The difference between the above embodiment and this embodiment is that: Figure 4 , Figure 5 , Figure 6 and Figure 8As shown, a conical through hole is provided inside the diffusion cover 106, and a water outlet 1062 is provided at the bottom of the conical through hole, and the water outlet 1062 is provided at the bottom of the diffusion cover 106, and the spiral track 1061 is installed on the conical through hole, the end of the guide plate 104 is in contact with the diffusion cover 106, and a baffle 1041 is provided on the outer wall of the end of the guide plate 104, and the height of the baffle 1041 is greater than the height of the guide plate 104. The deoxygenated water flows through the film rotary body 102 to the inside of the water film guide cover 103, and a certain gap is left between the end of the water film guide cover 103 and the surface of the tower shell 101. The water that finally falls flows downward from the bottom of the water film guide cover 103 and slides downward along the inside of the tower shell 101. Due to the small gap, the water flow falls slowly, thereby increasing the contact area between the steam and the water flow, thereby improving the treatment effect. The treated water flows along the tower shell 101, and through the action of the guide plate 104 and the spiral track 1061 at the bottom, the water flow can be driven to move in a spiral shape as a whole, thereby increasing the falling time of the water flow, thereby increasing the treatment time and improving the treatment effect.

[0048] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in a specific embodiment, a water grate 107 is installed inside the tower shell 101, and the water grate 107 is placed between the diffusion cover 106 and the heat storage filler 108. A support plate 1081 is provided on the top of the heat storage filler 108. A mounting plate 1082 is provided on the upper surface of the support plate 1081. The mounting plate 1082 is welded to the inner wall of the tower shell 101, and a locking bolt is screwed between the mounting plate 1082 and the support plate 1081. The treated water flows to the water grate 107, and can be evenly moved to the heat storage filler 108 through the water grate 107. The steam transported by the second steam delivery pipe can perform secondary deoxygenation on the water in the heat storage filler 108, thereby ensuring the thoroughness of deoxygenation.

[0049] like Figure 1 , Figure 2 and Figure 3As shown, further, telescopic brackets 2031 are installed on both sides of the heating resistance wire 203, and wires are arranged inside the telescopic brackets 2031, and the wires and the heating resistance wire 203 are connected to each other. The bottom of the telescopic brackets 2031 is installed on the inner side of the deaerator box 201, and the two ends of the deaerator box 201 are bolted together with an inspection door 2011, and the inspection door 2011 is provided with tempered glass inside the inspection door 201, and a pressure gauge 2012 is installed on the deaerator box 201. The deoxygenated water flow can be moved to the inside of the deaerator box 201, and the water flow temperature is increased by the internal heating resistance wire 203, so that the dissolved oxygen is analyzed from the inside, and a relatively pure deoxygenation operation is achieved. Among them, the telescopic bracket 2031 can control the change in the height of the heating resistance wire 203, and then the water flow at different positions can be heated, and the inspection door 2011 is convenient for later maintenance, and the pressure gauge 2012 is convenient for observing the internal pressure at all times.

[0050] Embodiment 3:

[0051] The difference between the above embodiment and this embodiment is that: Figure 1 , Figure 2 and Figure 3 As shown, a pair of support frames 202 are installed at the bottom of the deaerator box 201, and a bottom plate 2021 is fixedly arranged at the bottom of the pair of support frames 202. Four mounting holes 2022 are opened at the corners of the bottom plate 2021, and a discharge pipe with an electronic valve is installed at the bottom of the deaerator box 201. The bottom plate 2021 mainly plays a supporting role.

[0052] like Figure 1 , Figure 2 and Fig. 9As shown, in a specific embodiment, a baffle 3042 is installed at the bottom of the piston rod 304, and a return spring 3043 is sleeved on the outer wall of the piston rod 304 located on the inner side of the deaerator box 201. One side of the return spring 3043 is clamped on the inner wall of the deaerator box 201, and the other side is clamped on the inner wall of the baffle 3042. The inner diameter of the gas flow cavity 3011 located on the inner side of the pressure relief cover 301 gradually increases, and a baffle plate 3012 is installed on the gas flow cavity 3011 located at the largest diameter. After long-term use of the heat storage filler 108, impurities in the water will accumulate on the surface, which is prone to blockage. When blockage occurs, the entire interior of the second steam delivery pipe 1092 is filled into the deaerator box 201, causing the pressure inside the deaerator box 201 to rise sharply, and then the gas can enter the gas flow cavity 3011 through the pressure relief hole 3044, pushing the piston 3041 to move upward as a whole, and the movement of the piston 3041 drives the piston rod 304 to move upward, and then the return spring 3043 is compressed through the baffle 3042, and the return spring 3043 is used to facilitate the subsequent return processing. When the piston 3041 moves to the larger gas flow cavity 3011, the internal gas can flow outward at high speed through the gas flow cavity 3011 and be discharged outward from the output pipe 302.

[0053] like Figure 1 , Figure 2 and Fig. 9 As shown, further, a first guide plate 3022 and a second guide plate 3023 are installed on the gas flow cavity 3011 located in the output pipe 302, the first guide plate 3022 and the second guide plate 3023 are conical, and the outlets of the first guide plate 3022 and the second guide plate 3023 and the push plate 3051 at the bottom correspond to each other, a mounting groove 3021 is opened inside the output pipe 302, and the mounting groove 3021 is movably connected with the rotation center of the turntable 305, a torsion spring 3032 is clamped between the sound plate 3031 and the inner wall of the warning box 303, and a sound transmission hole is opened on the surface of the warning box 303. During the gas circulation process, the gas can blow the push plate 3051 at the bottom through the first guide plate 3022 and the second guide plate 3023, thereby driving the turntable 305 to start rotating clockwise, and the push plate 3051 on the turntable on the other side collides with the sound plate 3031, and the sound plate 3031 rotates and makes a sound, which has the effect of an alarm. After the sound plate 3031 rotates, it is driven to reset by the torsion spring 3032, which facilitates the uninterrupted alarm.

[0054] The implementation principle of a rotary film deaerator in this embodiment is as follows:

[0055] First, the deoxygenated water needs to be continuously injected into the inside of the rotary film body 102 through the water inlet pipe 1021, and then high-pressure steam needs to be input into the first steam delivery pipe 105 and the second steam delivery pipe 1092. The rotary film body 102 and the first steam delivery pipe 105 cooperate with each other to deoxygenate a portion of the treated liquid, and then the deoxygenated water moves to the inside of the water film guide cover 103 through the rotary film body 102. There is a certain gap between the end of the water film guide cover 103 and the surface of the tower shell 101. The falling water flows downward from the bottom of the water film guide cover 103 and slides downward along the inside of the tower shell 101. Due to the small gap, the water flow falls slowly, thereby increasing the contact area between the steam and the water flow, thereby improving the treatment effect.

[0056] The treated water flows along the tower shell 101, and through the action of the guide plate 104 and the spiral track 1061 at the bottom, the water flow can be driven to move in a spiral shape as a whole, thereby increasing the falling time of the water flow, thereby increasing the treatment time and improving the treatment effect.

[0057] The treated water flow moves to the water sprinkling grate 107, and can be evenly moved to the heat storage filler 108 through the water sprinkling grate 107. The steam transported by the second steam delivery pipe can perform secondary deoxygenation on the water in the heat storage filler 108, thereby ensuring the thoroughness of deoxygenation. The deoxygenated water flow can move to the inside of the deoxygenation box 201, and the internal heating resistor 203 can increase the water flow temperature, thereby analyzing the dissolved oxygen from the inside, achieving a relatively pure deoxygenation operation.

[0058] After long-term use of the heat storage filler 108, impurities in the water will accumulate on the surface, which is easy to cause blockage. When blockage occurs, the entire interior of the second steam delivery pipe 1092 is filled into the deaerator box 201, causing the pressure inside the deaerator box 201 to rise sharply, and then the gas can enter the gas flow cavity 3011 through the pressure relief hole 3044, pushing the piston 3041 to move upward as a whole, and the movement of the piston 3041 drives the piston rod 304 to move upward, and then the return spring 3043 is compressed by the baffle 3042, and the return spring 3043 is used to facilitate the subsequent return process. When the piston 3041 moves to After the larger gas flow cavity 3011 is formed, the internal gas can flow outward at high speed through the gas flow cavity 3011 and be discharged outward from the output pipe 302. During the gas circulation process, the gas can blow the push plate 3051 at the bottom through the first guide plate 3022 and the second guide plate 3023, thereby driving the turntable 305 to start rotating clockwise, and the push plate 3051 and the sound plate 3031 on the turntable on the other side collide, and the sound plate 3031 rotates and makes a sound, which has the effect of an alarm. After the sound plate 3031 rotates, it is driven to reset through the torsion spring 3032, which is convenient for uninterrupted alarm.
