Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of hydrophobicity, in particular to a hydrophobic collector. Background Art
[0002] Currently, for long-distance heating corridors and overhead steam pipelines, the steam pipe drainage and drainage piping is relatively dispersed. In addition to the need for drainage devices at low points in the pipelines, drainage devices should generally be installed every 200 to 300 meters. Condensate discharged from the drainage devices should be discharged into condensate pipes. When drainage into condensate pipes is not possible, for overhead steam pipelines, the drainage water is generally discharged into a nearby ditch or other safe drainage area. For long-distance transmission corridors, condensate is generally discharged into dedicated drainage wells.
[0003] For overhead steam pipelines, since the drainage water is a steam-water mixture, the escaping steam can easily dampen the insulated pipes on the pipe racks and obstruct the sight of valve operators, creating unsafe and unsightly conditions for the plant environment and posing a safety hazard to cables laid parallel to the steam pipelines. For long-distance heating pipeline corridors, drain wells are used to discharge and collect drainage water. However, digging drain wells can be inconvenient from a construction, land occupation, maintenance, and economic perspective. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] The present invention provides a hydrophobic collector 10, see Figures 1 to 6 , comprising a cylinder 100 and a condensation structure 400. Specifically, at least one access pipe 200 is connected to the top of the cylinder 100, and a drain pipe 300 is connected to the lower side wall of the cylinder 100. The drain pipe 300 and the at least one access pipe 200 are respectively communicated with the inner cavity 110 of the cylinder 100; the condensation structure 400 is arranged in the inner cavity 110 of the cylinder 100 and is located above the drain pipe 300. The condensation structure 400 has a plurality of partitions 410 spaced apart along the axial direction of the cylinder 100, one end of each partition 410 is connected to the inner wall of the cylinder 100, and an overflow channel 500 is formed between the other end of each partition 410 and the inner wall of the cylinder 100, and the free end of each partition 410 is inclined toward the bottom direction of the cylinder 100.
[0029] The drain collector 10 of the present invention can effectively reduce the dispersion of drained water vapor, so that the drained water vapor can be effectively condensed, reducing the temperature and air humidity of the drain area, thereby reducing damage to the pipe rack insulation structure, etc., and at the same time reducing the excavation construction, investment funds, maintenance and operation costs of drain wells in long-distance steam transmission pipelines.
[0030] In some operating modes, each access pipe 200 is connected to the outlet of the corresponding steam pipe's drain valve assembly. Within the structural strength tolerance of the drain collector 10, the number of access pipes 200 can be adjusted based on the number of drain valve assemblies at the same steam drain point, thereby simultaneously processing the drain steam from multiple steam pipes at the same steam drain point. In other operating modes, the drain water from the heating pipe gallery can be diverted to a safe location and connected to the drain collector 10, replacing the drain well in existing operating modes, thereby reducing equipment space and lowering construction and operating costs.
[0031] In some embodiments, see Figures 1 to 4 The partition 410 is a flat plate, which is composed of a first plate 411 and a second plate 412. The first plate 411 and the second plate 412 are both part of a circular plate. The center A of the circular plate where the first plate 411 is located and the center B of the circular plate where the second plate 412 is located are at a preset distance S. That is, when the preset distance between the center A of the circular plate where the first plate 411 is located and the center B of the circular plate where the second plate 412 is located is S, the area where the circular plates where the first plate 411 is located and the circular plates where the second plate 412 is located overlap form the partition 410. For details, please refer to Figure 4 and Figure 6 The shape of each partition 410 is similar to an ellipse, and part of its periphery is connected to the inner wall of the cylinder 100, while the other periphery forms a flow channel 500 with the inner wall of the cylinder 100.
[0032] For further information, see Figure 2 and Figure 4, the diameter D1 of the circular plate where the first plate 411 is located, the diameter D2 of the circular plate where the second plate 412 is located, and the diameter D of the cross section of the cylinder 100 are all the same, and the distance S is less than 1 / 2 of the inner diameter d of the cylinder 100 (that is, the diameter D of the cross section of the cylinder 100). In some preferred embodiments, the distance S is 1 / 8 to 1 / 4 of the inner diameter d of the cylinder 100 (that is, the diameter D of the cross section of the cylinder 100). In the present invention, the more drainage pipes connected to the access pipe 200 (that is, the more drainage water vapor entering the inner cavity 110 of the cylinder 100), the larger the value of the distance S is selected, so that the area of the partition 410 obtained is smaller, and the flow area of the flow channel 500 formed between the other end of each partition 410 and the inner wall of the cylinder 100 is larger, which is more conducive to the flow of drainage water vapor.
[0033] For further information, see Figure 2 and Figure 5 The angle α formed between the partition 410 and the radial direction of the cylinder 100 is 3° to 8°. Preferably, the angle α formed between the multiple partitions 410 and the radial direction of the cylinder 100 is the same, which is more convenient during construction. Of course, the angle α formed between the multiple partitions 410 and the radial direction of the cylinder 100 can also be adjusted to different degrees according to actual working conditions, thereby improving the adaptability of the partitions 410 under different working conditions and ensuring their condensation effect.
[0034] By arranging the baffles 410 at an angle, the present invention ensures that after condensation, the discharged water vapor flows along the flow direction F of the discharged water vapor through the flow channel 500 and is discharged into the lower part of the inner cavity 110 of the cylinder 100. As a result, due to the action of gravity, the condensed water cooperates with the condensation structure 400 along the flow direction F of the discharged water vapor to complete the secondary condensation of the condensed water, thereby improving the condensation effect of the discharged water vapor and accelerating the discharge speed of the condensed water. In other embodiments, multiple baffles 410 can also be arranged parallel to each other, and each baffle 410 is arranged along the radial direction of the cylinder 100.
[0035] In some embodiments, see Figures 1 to 6 At least one baffle ring 600 is connected to the upper surface of each baffle 410. Specifically, the baffle ring 600 is formed by a plate strip connected at the head and tail, and the lower end of the plate strip is fixedly connected to the upper surface of the baffle 410. By providing the baffle ring 600, the present invention can increase the contact area between the discharged water vapor and the baffle ring 600 and prolong the stagnation time of the discharged water vapor on the upper surface of the baffle 410, thereby facilitating the condensation of the discharged water vapor on the baffle ring 600, thereby enhancing the condensation effect of the condensation structure 400.
[0036] In some preferred embodiments, see Figures 1 to 5There is one baffle ring 600. The center C1 of the baffle ring 600 coincides with the center C of the partition 410. The diameter D3 of the baffle ring 600 is less than or equal to half the length L of the minor axis of the partition 410. The height H of the baffle ring 600 is 1 / 50 to 1 / 5 of the diameter D3 of the baffle ring 600.
[0037] In other preferred embodiments, see Figure 6 There are two baffle rings 600 , the center C1 of each baffle ring 600 is located on the minor axis of the partition 410 , and the distance S1 between the center C1 of each baffle ring 600 and the edge of the minor axis of the partition 410 is 1 / 4 of the minor axis length L of the partition 410 .
[0038] In other embodiments, the number of baffle rings 600 may be other numbers, and the baffle rings 600 are evenly spaced along the minor axis of the partition 410, thereby further increasing the contact area between the water vapor and the baffle rings 600. Of course, in other embodiments, the baffle rings 600 are evenly distributed on the upper surface of the partition 410.
[0039] In some embodiments, see Figure 1 A filter screen 700 is provided at the location where the drain pipe 300 is connected to the cylinder 100. By providing the filter screen 700, large particles of impurities such as rust contained in the drain water in the cylinder 100 can be effectively filtered out and the large particles of impurities filtered out by the filter screen 700 are deposited at the bottom of the inner cavity 110 of the cylinder 100, thereby avoiding clogging of the drain pipe 300 and improving the quality of the liquid discharged from the drain pipe 300.
[0040] For further information, see Figure 1 and Figure 2 A sewage outlet 800 is provided at the bottom of the cylinder 100, so that the sewage accumulated in the cylinder 100 can be discharged through the sewage outlet 800.
[0041] In some embodiments, see Figure 2 The two adjacent partitions 410 form flow channels 500 with the inner wall of the cylinder 100, which are staggered vertically along the axial direction of the cylinder 100. This design allows the present invention to form channels within the condensation structure 400 for the discharge of water vapor, allowing the water vapor to condense along the flow direction F of the discharge of water vapor within the cylinder 100 through the condensation structure 400. This also increases the contact area between the discharge of water vapor and the partitions 410, thereby improving the condensation effect.
[0042] In some embodiments, see Figure 1 and Figure 2The lower end of the cylinder 100 is connected to a support 900 for supporting the cylinder 100. The present invention can facilitate the installation of the cylinder 100 on the ground by providing the support 900, and can also ensure the stability of the cylinder 100.
[0043] The above are only several embodiments of the present invention. Those skilled in the art may make various changes or modifications to the embodiments of the present invention based on the contents disclosed in the application documents without departing from the spirit and scope of the present invention.
