The water tank 103 is configured to receive the condensed water from the return chamber 104.
When the tail gas passes through the condensing sheet 106 from bottom to top, part of the tail gas meets the condensing sheet 106 to generate condensed water, and due to the inclined arrangement of the condensing sheet 106, the generated condensed water flows into the backflow hole 105 below the condensing sheet 106 under the action of gravity, so that the tail gas generates first water-vapor separation in the process; because the condensation sheet 106 has a gap, another portion of the exhaust gas bypasses the condensation sheet 106 and continues to be discharged upwards, and meets another condensation sheet 106 located on the outer wall of the reflow chamber 104 again to perform a second water-vapor separation. Then, through be in the backward flow chamber 104 outer wall sets up a plurality of condensation sheets 106, make tail gas is through a lot of water vapor separation backs, and the comdenstion water of production passes through each the backward flow hole 105 flows into in the backward flow chamber 104, and all the other tail gases bypass condensation sheet 106 upwards discharges, finally discharges through the gas outlet, condensation sheet 106 and the setting of backward flow chamber 104 has increased tail gas exhaust's route to make tail gas through a lot of water vapor separation, thereby realize the water vapor separation of degree of depth, reduce the steam content in the tail gas after the tail gas discharge.
In this embodiment, the method further includes: and the water-vapor primary separation unit is positioned between the condensation sheet 106 and the water tank 103 and comprises a cooling water spray head 107 and water-vapor separation filling particles 108 positioned below the cooling water spray head 107.

In this embodiment, the method further includes: and the exhaust pipe 11 is positioned outside the cavity 10 and communicated with the air outlet 102, and the pressure value in the exhaust pipe 11 is smaller than the pressure value in the cavity 10.
The differential pressure return chamber 109 has a second bottom port 1091, and the second bottom port 1091 is lower than the top of the water tank 103. In practical use, the pressure difference reflux cavity 109 and the bottom of the reflux cavity 104 can be extended to the position below the liquid level in the water tank 103, so that the bottom of the pressure difference reflux cavity 109 is hermetically communicated with the bottom of the reflux cavity 104, the bottom of the pressure difference reflux cavity 109 is hermetically communicated with the water tank 103, the exhaust pipe 11 is communicated with the reflux cavity 104, and condensed water can conveniently enter the reflux cavity 104 through the reflux hole 105 by utilizing the pressure difference between the exhaust pipe 11 and the cavity 10.
The ratio of the cross-sectional diameter size range of the differential pressure return cavity 109 to the return cavity 104 is 1:1 to 5:4. the significance of selecting the size range ratio is that the pressure difference between the inside and the outside of the backflow hole 105 can be caused by the difference between the pressure inside the exhaust pipe 11 and the pressure inside the cavity 10, the pressure difference backflow cavity 109 is too small to form the pressure difference between the inside and the outside of the backflow hole 105, and the pressure difference backflow cavity 109 is too large to affect the installation of the condensation sheet 106, so that the gap between the condensation sheet 106 and the cavity 10 is too large, and the tail gas can be directly discharged upwards through the gap. In particular, the pressure difference is large enough to facilitate the inflow of the condensed water into the return hole 105. In this embodiment, the cross-sectional diameter size ratio of the differential pressure return cavity 109 to the return cavity 104 is 1:1.
in this embodiment, the method further includes: a baffle 110 fixed to an inner sidewall of the bottom of the reflow chamber 104, wherein the baffle 110 has a third end 1101 fixed to the bottom sidewall of the reflow chamber 104 and a fourth end 1102 inclined toward the surface of the water tank 103 and the differential pressure reflow chamber 109 with respect to the third end 1101.
The flow guide plate 110 facilitates the condensed water to flow into the water tank 103, thereby reducing the probability that the condensed water is brought into the exhaust duct 11 through the differential pressure return chamber 109. Specifically, when the distance difference between the liquid level in the water tank 103 and the fourth end 1102 is greater than 5cm, the baffle 110 can achieve a better effect.
In this embodiment, a gap is formed between the condensation sheet 106 and the wall of the chamber 10. Specifically, the distance X between the condensation sheet 106 and the cavity wall of the cavity 10 is 3cm to 8cm, which is beneficial for part of the tail gas to bypass the condensation sheet 106 and be discharged upwards, and the upwards discharged tail gas can be subjected to multiple water-vapor separation.
In this embodiment, the reflow chamber 104 is a cylinder, the projection of the notch of the condensation plate 106 on the horizontal plane is a fan shape, and the fan shapes of the notches of the adjacent condensation plates 106 on the horizontal plane are not overlapped. In other embodiments, the cross section of the backflow cavity may be in other polygonal shapes such as a square, the condensing sheet surrounds the backflow cavity in shape, the projection of the condensing sheet on the horizontal plane may be in a polygon, the backflow cavity guides condensed water into the water tank, and the condensing sheet is used for blocking the tail gas and generating condensed water, so that the condensing sheet is not limited to the above shape.
The sector of the gap projection of the adjacent condensing sheet 106 on the horizontal plane is not overlapped, which is beneficial to increasing the upward exhaust path of the tail gas and realizing the water-vapor separation.
In this embodiment, the number of the condensation sheets 106 is 4, and the projection area of the notch on the horizontal plane is 1/3 of the projection area of the condensation sheet 106 on the horizontal plane. The gaps of the adjacent condensing sheets 106, such as the condensing sheet a and the condensing sheet B, have a rotation angle of 90 degrees with respect to each other in the fan shape projected on the horizontal plane. In this embodiment, the projection of tail gas path from bottom to top on the horizontal plane is a circumference to make partial tail gas be the ascending trend of helix and upwards discharge, the mode of placing of fan piece has increased the route of steam-water separation, thereby realizes increasing the effect of steam-water separation, condensation piece 106 is less in quantity, but can accomplish better steam-water separation effect.
In other embodiments, the number of the condensation sheets 106 may be increased to 8, the projection of the tail gas from the bottom to the top on the horizontal plane is two circles, so that part of the tail gas is discharged upwards in a spiral ascending trend, and the fan sheets are arranged in a manner of increasing the path of water-vapor separation, thereby achieving the effect of increasing the water-vapor separation. The number of the condensation sheets is not limited to an integral multiple of 4, and may be any number of sheets larger than 1. That is, the number of the condensation sheets may not be limited, and the greater the number of the condensation sheets, the more the water vapor separation is facilitated, but the greater the number of the condensation sheets, the more the installation and production costs are increased, and a trade-off needs to be made between the cost and the water vapor separation effect.
The angle between the condensation sheet 106 and the direction perpendicular to the horizontal plane ranges from 40 degrees to 60 degrees. The different inclination angles of the condensation sheets 106 have different blocking abilities for the exhaust gas, which also determines different water-vapor separation effects. Within the angle range, a better tail gas water-vapor separation effect can be achieved. In other embodiments, the angle range may not be adopted, and an extreme example includes that the condensation sheets are distributed in a direction parallel to the horizontal direction, so that the formed condensation water is not easy to flow into the backflow holes; another extreme example includes that the condensation sheets are distributed along the direction perpendicular to the horizontal direction, so that no barrier is formed on the tail gas, and further condensed water is generated. When the angle range between the condensation sheet 106 and the direction perpendicular to the horizontal plane is greater than 0 degree but smaller than 90 degrees, the condensation sheet blocks the tail gas to form condensed water, and the condensed water flows into the backflow hole due to the inclined arrangement of the condensation sheet, so that the effect of water-vapor separation is generated.
The tail gas is easily discharged upwards by increasing the size of the notch of the condensation sheet 106, reducing the size of the condensation sheet 10, increasing the inclination angle of the condensation sheet 10, reducing the size of the backflow hole 105, increasing the size of the gap between the condensation sheet 106 and the cavity wall of the cavity 10, and the like. Conversely, reducing the size of the notch of the condensation sheet 106, increasing the size of the condensation sheet 10, reducing the inclination angle of the condensation sheet 10, increasing the size of the backflow hole 105, and reducing the size of the gap between the condensation sheet 106 and the cavity wall of the cavity 10 will increase the amount of the condensed tail gas entering the backflow hole 105. In short, the size of the gap of the condensation sheet 106, the size of the condensation sheet 10, the inclination angle of the condensation sheet 10, the size of the backflow hole 105, the size of the gap between the condensation sheet 106 and the cavity wall of the cavity 10, and the like, jointly determine the exhaust path, and the effect of water-vapor separation can be further optimized by optimizing the above parameters. Therefore, in other embodiments, the above parameter values may not be limited.
Fig. 4 is a schematic view showing the operation of the water-vapor separating apparatus of fig. 1.
The working process comprises the following steps: tail gas I enters the cavity 10 from the gas inlet 101, primary water-vapor separation is completed through the water-vapor primary separation unit, the tail gas I is continuously discharged from bottom to top, when the tail gas I passes through the condensing sheet 106, a part of tail gas II meets the condensing sheet 106 and then generates condensed water, due to the inclined arrangement of the condensing sheet 106, the generated condensed water flows into the backflow hole 105 below the condensing sheet 106 to form condensed water III, and the tail gas generates first water-vapor separation in the above process; another portion of the tail gas IV bypasses the condensation plate 106, i.e. it is continuously discharged upwards through the gap of the condensation plate 106 or the gap between the condensation plate 106 and the cavity wall of the cavity 10, and meets another condensation plate 106 on the outer wall of the reflow cavity 104 again for performing a second water-vapor separation. Then, through set up a plurality of condensation pieces 106 at the backward flow chamber 104 outer wall, make tail gas behind a lot of steam separation, the comdenstion water that produces passes through each the backward flow hole 105 flows into in the backward flow chamber 104, and all the other tail gases bypass condensation piece 106 upwards discharges, finally discharges through the gas outlet, condensation piece 106 and the setting of backward flow wall 104 has increased tail gas exhaust's route to make tail gas through a lot of steam separation, thereby realize the steam separation of degree of depth, reduce the steam content in the tail gas after the tail gas discharge.
In this embodiment, after the tail gas I sequentially passes through the condensation sheet a, the condensation sheet B, the condensation sheet C, and the condensation sheet D to complete the water-vapor separation for four times, the condensed water II further flows into the water tank 103 through the flow guide plate 110.
