The invention will be further described with reference to specific examples, but the scope of the invention is not limited thereto.
As shown in fig. 1 to 5, the emission reduction steam-water separator of the embodiment includes a separation cavity 1, a reboiling cavity 2 and a drainage cavity 3. The top end of the reboiling cavity 2 is connected with the separation cavity 1, and the bottom end is connected with the drainage cavity 3. A cyclone separator is arranged in the separation cavity 1. The separation cavity 1 is used for evaporating water vapor, the cyclone separator is used for separating the water vapor in the separation cavity 1, and the reboiling cavity 2 is used for evaporating liquid water separated from the water vapor. The drainage chamber 3 is used to drain the water vapor with which the inside of the reboiling chamber 2 is not evaporated. When the steam separator operates, the steam with water firstly enters the cyclone separator, the water with water and the steam with higher dryness are separated by the cyclone separator, and the steam with higher dryness directly flows out from the separation cavity 1 for users to use. The liquid moisture separated by the water vapor enters the reboiling cavity 2 to exchange heat with the high-temperature vapor in the reboiling cavity 2, one part of the liquid moisture is heated by the high-temperature vapor and is evaporated again to the separation cavity 1, and the rest small part of the water which is not evaporated in the reboiling cavity 2 automatically flows down the bottom drainage cavity 3 and is automatically discharged according to a boiler control system. Therefore, this embodiment can effectively improve the steam quality through the mutual cooperation of separation chamber 1, reboiling chamber 2 and drainage chamber 3, has carried boiler efficiency, realizes energy saving and emission reduction consumption reduction's purpose.
The cyclone separator comprises a separation chamber 4. An impeller 5 is arranged in the separation chamber 4, the top end of the separation chamber 4 is opened, and the bottom end of the separation chamber is provided with an inflow pipe 6. The inflow pipe 6 extends through the bottom wall of the separation chamber 1 and out of the separation chamber 1. The impeller 5 comprises a first blade 7 and a second blade 8, and a plurality of second blades 8 are uniformly distributed along the circumferential edge of the first blade 7. The edge of the first blade 7 of this embodiment is provided with eight second blades 8. The first blade 7 is disk-shaped, and the second blade 8 is fan-ring plate-shaped and bent into a certain radian integrally. The second blade 8 has a short curved edge connected to the first blade 7 and a long curved edge adjacent to the inner wall of the separation chamber 4. Two pairs of second blades 8 are directed obliquely upwards towards the open end of the separation chamber 4 and the other two pairs are directed obliquely downwards towards the bottom end of the separation chamber 4. The second blades 8 are formed in such a shape that the charged steam can be easily formed into a spiral shape. The inflow pipe 6 is located at the bottom of the separation chamber 1. The water vapor enters the separation chamber 4 through the inflow pipe 6, and impinges on the first blade 7 and the second blade 8, and the second impeller 5 rotating rapidly forms the water vapor into a spiral shape. Because the height of the separation chamber 4 is low, the spiral steam with water rises from the separation chamber 4 to the separation cavity 1, under the action of centrifugal force, the steam with water can separate out more water, the water flows into the reboiling cavity 2, and the dry steam flows out from the separation cavity 1. The central axes of the separation cavity 1, the separation chamber 4 and the first blade 7 are all positioned on the same straight line.
