[0003] The gas tank of the silo top dust collector cannot separate steam and water. In the absence of winter insulation measures or when the insulation measures are not in place, water vapor will enter the interior of the silo top dust collector, causing ice to form inside the dust collector in winter, thus affecting the use of the silo top dust collector. However, the existing steam-water separation structure (such as the steam-water separation device disclosed in CN212440670U) cannot effectively remove moisture when applied to the silo top dust collector.

[0030] refer to Figure 1-2 The gas-water separation structure of the present application includes a tank body 10, a plurality of first windshields 20 and a plurality of second windshields 30. The tank body 10 has a first end wall, a second end wall and a side wall connecting the first end wall and the second end wall. An air inlet 11 is arranged on the first end wall. An air outlet 12 and a water outlet 13 are arranged on the side wall. The air outlet 12 is located above the water outlet 13. A plurality of first windshields 20 and a plurality of second windshields 30 are staggeredly arranged inside the tank body 10 along the axial direction of the tank body 10, and the first windshield 20 and the second windshield 30 have a predetermined distance along the axial direction of the tank body 10. The air outlet 12 of the tank body 10 is close to the first windshield 20, and the water outlet 13 of the tank body 10 is close to the second windshield 30. The distance between each second wind shield 30 and the first wind shield 20 adjacent thereto and close to the air inlet 11 is recorded as m, and the distance between each second wind shield 30 and the first wind shield 20 adjacent thereto and far from the air inlet 11 is recorded as n, where m is smaller than n.

[0031] The present application adopts a staggered distribution of the first wind shield 20 and the second wind shield 30, so that after the gas enters the tank body 10, the movement path becomes longer and energy is lost due to collision, so that the gas movement speed is reduced. In addition, by setting the distance m between each second wind shield 30 and the first wind shield 20 adjacent to it and close to the air inlet 11 to be smaller than the distance n between each second wind shield 30 and the first wind shield 20 adjacent to it and far away from the air inlet 11, the movement speed of the gas slows down after passing through the narrow channel between the first wind shield 20 and the second wind shield 30 and entering a relatively large space, and the residence time in the tank body 10 is extended, so that the moisture in the gas can be fully condensed into liquid on the first wind shield 20 and the second wind shield 30, and flow to the bottom of the tank body 10 under the water's own gravity, realizing effective gas-water separation, thereby ensuring that the air entering the silo top dust collector is dry.

[0032] In the present application, the first wind shield 20 and the second wind shield 30 have a predetermined distance along the axial direction of the tank body 10, so that the first wind shield 20 and the second wind shield 30 do not contact each other. The "predetermined distance" can be adjusted according to the length of the tank body 10 and the actual dewatering requirements.

[0033] In some embodiments, m:n=1:(2-5). In some specific embodiments, m:n may be equal to 1:2, 1:3, 1:4 or 1:5. Optimizing the ratio of m to n is conducive to further reducing the flow velocity of the gas in the tank body 10, prolonging the residence time of the gas in the tank body 10, and thus improving the dehydration efficiency.

[0034] In some embodiments, Figure 1-2 As shown, the tank body 10 is cylindrical. Figure 3 As shown, each first wind deflector 20 is in an arcuate shape. Figure 4 As shown, the shape of each second wind shield plate 30 is oblate. The diameter of each first wind shield plate 20 and each second wind shield plate 30 is equal to the inner diameter of the tank body 10.

[0035] The diameter of the first arcuate windshield 20 is the same as the inner diameter of the tank body 10, so it can fit well with the circular inner wall of the tank body 10. Similarly, the diameter of the second oblate windshield 30 is the same as the inner diameter of the tank body 10, so it can also fit well with the circular inner wall of the tank body 10. In this way, the gap between the windshield and the inner wall of the tank body 10 can be reduced, and the probability of gas colliding with the first windshield 20 and the second windshield 30 can be increased, thereby improving the dehydration efficiency.

[0036] In some embodiments, each first wind deflector 20 and each second wind deflector 30 are welded to the inner wall of the tank body 10 .

[0037] In some embodiments, continue to refer to Figure 2 The tank body 10 is cylindrical, the height of each first wind shield plate 20 is recorded as L1, the height of each second wind shield plate 30 is recorded as L2, the diameter of the tank body 10 is recorded as D, 1 / 2D≤L1≤3 / 4D, 1 / 2D≤L2≤3 / 4D.

[0038] By optimizing the height of the first wind shield 20 and the second wind shield 30, the dehydration efficiency is improved. According to experimental tests, when the height of the first wind shield 20 and the second wind shield 30 is too large, the gas flow is blocked, which is not conducive to the circulation in the tank body 10, so the dehydration efficiency is not high; and when the height is too small, the first wind shield 20 and the second wind shield 30 cannot play an effective dehydration role, which also leads to a decrease in the dehydration efficiency. When the height is selected within the above range, the dehydration effect of the steam-water separation structure is significantly improved, and the dehydration efficiency can reach more than 90%.

[0039] In some specific embodiments, L1 may be 1 / 2D, 5 / 8D, or 3 / 4D. L2 may be 1 / 2D, 5 / 8D, or 3 / 4D.

[0040] In some embodiments, continue to refer to Figure 2 The first windshield 20 and the second windshield 30 have overlapping parts in the height direction. The overlapping parts are conducive to changing the flow direction of the gas, extending the flow path, and increasing the residence time of the gas in the tank body 10. In addition, the overlapping parts can also increase the collision probability between the gas and the windshield, thereby improving the gas-water separation efficiency.

[0041] In some specific embodiments, the length of the overlapping portion is recorded as L3, 1 / 6D≤L3≤1 / 4D. By optimizing the length of the overlapping portion, the dehydration efficiency is improved. If the length of the overlapping portion is too large or too small, it is not conducive to dehydration. Within the above height range, the dehydration effect of the steam-water separation structure is significantly improved, and the dehydration efficiency can reach more than 90%.

[0042] In some specific embodiments, L3 may be 1 / 6D, 5 / 24D, or 1 / 4D.

[0043] In some embodiments, continue to refer to Figure 2 The plurality of first wind deflectors 20 and the plurality of second wind deflectors 30 are arranged alternately in sequence along the axial direction from close to the air inlet 11 to far away from the air inlet 11. Figure 2 As shown, the windshield closest to the air inlet 11 is the first windshield 20. Since the gas entering the tank body 10 from the air inlet 11 tends to flow above the tank body 10, the first windshield 20 is first arranged near the air inlet 11, which is more conducive to improving the dehydration efficiency. If the windshield closest to the air inlet 11 is the second windshield 30, since the windshield is located at the lower part of the tank body 10, the airflow easily bypasses the windshield and continues to flow, causing the windshield to fail to play its due role and reducing the dehydration efficiency.

[0044] In some embodiments, continue to refer to Figure 2 A water flow channel 40 is formed between the second wind shields 30 and the side wall of the tank body 10. The water flow channel 40 extends in a direction parallel to the axial direction of the tank body 10 and is connected to the water outlet 13. The water condensed on the first wind shield 20 and the second wind shield 30 drips into the water flow channel 40 and is uniformly discharged through the water outlet 13, thereby ensuring that the gas entering the interior of the silo top dust collector is dry. The number of water outlets 13 is not particularly limited, and can be 1, 2 or more, and can be set as needed.

[0045] In some embodiments, continue to refer to Figure 2, a water outlet 13 may be provided, and the water outlet 13 is close to the air inlet 11. The moisture content of the gas near the air inlet 11 inside the tank body 10 is usually high, and the moisture is more likely to condense after passing through the first windshield 20 and the second windshield 30 near the air inlet 11, so more condensed water will be formed near the air inlet 11. Setting the water outlet 13 at a position close to the air inlet 11 is more conducive to timely removal of water.

[0046] The arrangement density of the first wind shield 20 and the second wind shield 30 can be determined according to the moisture content in the gas to be separated. The greater the moisture content, the higher the arrangement density. The density of the first wind shield 20 and the second wind shield 30 can be adjusted as needed to achieve a good effect of water vapor separation according to the moisture conditions in different regions, so that the gas discharged from the gas outlet 12 is drier.

[0047] The main working principle of the gas-water separation structure of the present application is: connected with the air inlet 11 through an external pipeline, compressed gas with water is introduced into the tank body 10, and the compressed gas directly contacts the first wind shield 20, so that water flows vertically into the tank body 10 along the first wind shield 20 under the action of gravity. Since some water vapor is still in a free state, a second wind shield 30 is also provided behind the first wind shield 20, which can effectively prevent water vapor from moving in the tank body 10, and condense the remaining water vapor on the wind shield, thereby effectively removing moisture from the gas.

[0048] The steam-water separation structure of the present application is improved on the basis of maintaining the original structure, has a simple design structure, low cost, and a wide range of applications, and can be applied to all steam-water separation scenarios.

[0049] The second aspect of the present application provides a silo top dust collector, comprising: a dust removal body and a steam-water separation structure, wherein the air outlet 12 of the steam-water separation structure is connected to the air inlet of the dust removal body, and the steam-water separation structure is the steam-water separation structure of the first aspect of the present application.

[0050] When in use, the tank body 10 of the steam-water separation structure can be connected to the outer shell of the silo top dust collector by a strap. The steam-water separation structure can be placed horizontally. A water outlet valve can be provided at the water outlet 13 on the tank body 10 of the steam-water separation structure, and liquid water in the tank body 10 can be discharged through the water outlet valve. An air outlet valve can be provided at the air outlet 12 on the tank body 10 of the steam-water separation structure, and the air outlet valve is connected to the air inlet of the silo top dust collector to pass dry gas into the silo top dust collector.
