[0035] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0036] Please refer to Figure 1 , this embodiment provides a steam demisting device 200. The steam demisting device 200 includes a main body 210, a diffuser copper tube group 220, a rotating blade 230, and a condensation assembly 240;

[0037] The main body 210 includes an inner cavity 211, an air inlet, and an air outlet. The air inlet and the air outlet are both communicated with the inner cavity 211 and are distributed at opposite ends of the main body 210;

[0038] The diffuser copper tube group 220 is communicated with the air inlet, and the diffuser copper tube group 220 is used to introduce steam into the main body 210;

[0039] The rotating blade 230 is rotatably arranged in the main body 210, and the rotating blade 230 is used to rotate relative to the main body 210 under the action of steam;

[0040] The condensation assembly 240 is accommodated in the inner cavity 211 and is used to condense the steam in the inner cavity 211 into water.

[0041] Please refer to Figure 1 , the working principle of the steam demisting device 200 is as follows:

[0042] The steam demisting device 200 includes a main body 210, a diffuser copper tube group 220, a rotating blade 230, and a condensation assembly 240; the main body 210 includes an inner cavity 211, an air inlet, and an air outlet. The air inlet and the air outlet are both communicated with the inner cavity 211 and are distributed at opposite ends of the main body 210; the diffuser copper tube group 220 is communicated with the air inlet, and the diffuser copper tube group 220 is used to introduce steam into the main body 210; the rotating blade 230 is rotatably arranged in the main body 210, and the rotating blade 230 is used to rotate relative to the main body 210 under the action of steam; the condensation assembly 240 is accommodated in the inner cavity 211 and is used to condense the steam in the inner cavity 211 into water.

[0043] Thus, when steam is introduced into the inner cavity 211 through the diffuser copper tube group 220, it can drive the rotating blade 230 to rotate relative to the inner cavity 211, so that the energy of the steam can be consumed in this way. And after the steam is introduced into the inner cavity 211 through the diffuser copper tube group 220, the steam in the inner cavity 211 can be condensed into water by the condensation assembly 240 accommodated in the inner cavity 211. Therefore, the steam demisting device 200 can consume the energy in the steam and condense the steam into water for easy recovery, thereby reducing the white pollution of steam during the steam emission process.

[0044] Furthermore, please refer to Figure 1 , in this embodiment, when setting the condensation assembly 240, the condensation assembly 240 includes a condensation copper tube group 241. At least part of the condensation copper tube group 241 is accommodated in the inner cavity 211, and the condensation copper tube group 241 is used to condense the steam in the inner cavity 211 into water.

[0045] It should be noted that in such a way, it adopts heat exchange between the cooling water flowing in the condensation copper tube group 241 and the steam in the inner cavity 211, so as to reduce the temperature of the steam and condense it into water. Thus, while the steam in the inner cavity 211 is condensed into water, the heat of the steam in the inner cavity 211 is transferred to the cooling water in the condensation copper tube group 241. Therefore, in this way, the cooling water can play a role in heat recovery. Specifically, the cooling water can adopt the condensate water of the steam turbine hot well. After being cooled by using this condensate water, the temperature of the condensate water can be increased and part of the heat can be recovered; soft water demineralized water can also be adopted, and after the temperature of the demineralized water is increased, it is sent to the boiler deaerator for use to recover part of the heat.

[0046] Moreover, when setting the condensation copper tube group 241, the condensation copper tube group 241 is located on the side of the rotating blade 230 away from the air inlet. That is, the steam entering the inner cavity 211 will pass through the condensation copper tube group 241 during the process of moving in the direction of the air outlet after driving the rotating blade 230 to rotate.

[0047] Based on the above structural settings, please refer to Figure 1 , in this embodiment, the steam demisting device 200 further includes a wind guide plate 251 connected to the main body 210. The wind guide plate 251 is arranged around the outer periphery of the diffuser copper tube group 220 to form a heat dissipation cavity 252 for accommodating the diffuser copper tube group 220;

[0048] The wind guide plate 251 is provided with an inlet 253 for air flow to enter the heat dissipation cavity 252 and an outlet 254 for the air flow in the heat dissipation cavity 252 to be discharged. And the air flow introduced into the heat dissipation cavity 252 through the inlet 253 is discharged through the outlet 254 after exchanging heat with the diffuser copper tube group 220.

[0049] Thus, in this way, a heat dissipation cavity 252 for cooling the diffuser copper tube group 220 can also be formed; furthermore, in this way, the efficiency of reducing the temperature of the steam can be improved.

[0050] Furthermore, please refer to Figure 1 , in this embodiment, the steam demisting device 200 further includes a first fan 261. The first fan 261 is rotatably connected to the main body 210, adjacent to the inlet 253, and in transmission connection with the rotating blade 230; the first fan 261 is used to rotate under the driving action of the rotating blade 230 to introduce external air into the inlet 253. In addition, the steam demisting device 200 may further include a second fan 262. The second fan 262 is rotatably connected to the main body 210, adjacent to the outlet 254, and in transmission connection with the rotating blade 230; the second fan 262 is used to rotate under the driving action of the rotating blade 230 to discharge the air in the heat dissipation cavity 252. It should be noted that when setting the first fan 261 and the second fan 262, the first fan 261 can be selected to be set, or both the first fan 261 and the second fan 262 can be set simultaneously.

[0051] In this embodiment, the method of setting both the first fan 261 and the second fan 262 is adopted. By setting the first fan 261 and the second fan 262 at the inlet 253 and the outlet 254 respectively, the speed of the air flow passing through the heat dissipation cavity 252 can be increased, thereby improving the heat exchange efficiency of the diffuser copper tube group 220 in the heat dissipation cavity 252 and thus increasing the cooling speed of the steam. And since both the first fan 261 and the second fan 262 are in transmission connection with the rotating blade 230, therefore, both the first fan 261 and the second fan 262 rotate under the driving action of the rotating blade 230, that is, while the first fan 261 and the second fan 262 rotate to increase the flow rate of the air flow, they can further consume the energy of the steam introduced into the inner cavity 211. When setting the first fan 261 and the second fan 262, in order to make the settings of the first fan 261 and the second fan 262 increase the flow rate of the air flow passing through the heat dissipation cavity 252, therefore, both the first fan 261 and the second fan 262 are turbine fans, and the blade angles of the first fan 261 and the second fan 262 are opposite.

[0052] Furthermore, in this embodiment, when the steam pressure is relatively low, in order to improve the heat exchange efficiency of the diffuser copper tube group 220 in the heat dissipation cavity 252, therefore, the steam demisting device 200 further includes a motor connected to the main body 210, and the motor is used to drive the first fan 261 or the second fan 262 to rotate.

[0053] Based on the above content, please refer to Figure 1 and Figure 2, the present invention further provides a steam de - whitening system 300. The steam de - whitening system 300 includes a blow - off silencer 310, an exhaust pipe 320, a sump 330, a drain pipe 340, and the above - mentioned steam de - whitening device 200;

[0054] Among them, the two ends of the exhaust pipe 320 are respectively communicated with the air outlet and the blow - off silencer 310; the two ends of the drain pipe 340 are respectively communicated with the air outlet and the sump 330.

[0055] Thus, during the operation of the steam de - whitening system 300, after the external steam enters the steam de - whitening device 200, it is condensed into water, and the condensed water can be introduced into the sump 330 through the drain pipe 340 for collection and treatment, while the remaining gas can be introduced into the blow - off silencer 310 through the exhaust pipe 320 for discharge.

[0056] In addition, since the gas introduced into the blow - off silencer 310 through the exhaust pipe 320 may contain water, the steam de - whitening system 300 further includes a return pipe 350. The two ends of the return pipe 350 are respectively communicated with the blow - off silencer 310 and the sump 330, so as to recover the water in the gas introduced into the blow - off silencer 310 through the exhaust pipe 320.

[0057] It should be noted that the water in the sump 330 can be supplied for use by setting an outlet pipe 360. When setting the outlet pipe 360, a self - priming pump and a check valve are provided on the outlet pipe 360.

[0058] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any change or substitution that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
