Description

Technical Field

[0001] The present invention relates to the technical field of filtration devices, and particularly relates to a filtration component and a horizontal filtration separator. Background Art

[0002] Compared with vertical filtration separators, horizontal separators have a large gas processing capacity, are convenient for replacing filter elements, and the quick-opening blind plate is very safe to operate. The existing horizontal filtration separator includes a cylinder body, multiple filter elements and multiple support pipes. Each filter element is coaxially connected to a support pipe, and multiple support pipes form a support pipe bundle. The air inlet of the horizontal filtration separator is located at the top of the cylinder body, and the air inlet is located laterally to the support pipe bundle and faces the support pipe bundle. After the gas enters the separator perpendicular to the support pipe from the air inlet, it first impacts the support pipe bundle. Blocked by the support pipe bundle, the gas flow direction changes from the vertical direction to the horizontal direction parallel to the support pipe, and then flows into the filter element area. Therefore, the support pipe bundle can not only support multiple filter elements, but also play a role in changing the direction of the high-speed gas entering from the air inlet, preventing the high-speed gas at the inlet from directly impacting the filter element.

[0003] The overall separation performance of the horizontal filtration separator mainly depends on its core component, the filter element, and generally dozens of filter elements are installed inside the separator at the same time. When the gas processing capacity of the filter element exceeds the maximum range it can allow, the filtration gas velocity exceeds the designed gas velocity, which easily causes the filter element to fail and thus shortens its service life; on the contrary, when the gas processing capacity of the filter element is lower than the designed range of the gas processing capacity, it will cause the filter element to fail to achieve the expected effect of filtration and separation, resulting in excessive waste of input resources. Therefore, to ensure the stable operation of the horizontal filtration separator, it essentially requires the filter element inside it to operate at the rated filtration gas velocity.

[0004] Problems existing in the existing horizontal filtration separator are:

[0005] After the gas enters the support pipe area, it will be blocked by the support pipe bundle to varying degrees. The more support pipes the gas passes through, the greater the blocking effect, and the more the gas velocity decreases. On the radial cross-section of the support pipe bundle, the gas velocity decreases vertically from the top area of the support pipe bundle to the bottom area of the support pipe bundle, resulting in uneven gas velocity distribution, causing turbulent disturbance of the gas in the support pipe area, uneven gas velocity distribution when the gas enters the filter element horizontally, and different gas volume distributions entering the filter element area horizontally per unit time, resulting in differences in the gas processing capacity and filtration speed of different filter elements. In the area where the gas velocity is too high, the gas flow velocity exceeds the rated filtration gas velocity of the filter element, the gas processing capacity of the filter element per unit time increases, and the gas load entering the filter element increases, causing the filter element to fail more quickly. While the filtration and separation performance of the filter element in the area where the gas velocity is too low is lower than the expected level, affecting the effective operation time of the horizontal filtration separator and resulting in the outlet gas of the equipment not meeting the design performance of the equipment. Summary of the Invention

[0006] In view of this, in order to solve the problem that the uneven gas processing capacity of the existing filter separator filter element is likely to cause the filter element to fail or the filter element cannot achieve the expected effect of filtration and separation, the technical solution of the present invention is proposed.

[0010] In the filtering component as described above, the increase amount of the pore diameter of the multiple rows of air holes along the air inlet direction is proportional to the increase amount of the linear distance of the multiple rows of air holes along the air inlet direction and satisfies a linear relationship.

[0030] Example 1

[0031] As Figures 1 to 3As shown in the figure, the present invention provides a filtering component 1, which includes a rectifying plate 11, a plurality of filter elements 12 and a plurality of support tubes 13; the rectifying plate 11 is disc-shaped, and the rectifying plate 11 is provided with a plurality of tube holes 111 arranged at equal intervals. The number of filter elements 12, the number of support tubes 13 and the number of tube holes 111 are all equal. A plurality of support tubes 13 are respectively inserted into a plurality of tube holes 111. The plurality of support tubes 13 and the plurality of filter elements 12 are coaxially butted respectively and are located on opposite sides of the rectifying plate 11. That is, the axes of the plurality of support tubes 13 and the axes of the plurality of filter elements 12 are both parallel to the axis of the tube holes 111 and perpendicular to the rectifying plate 11. Any three adjacent tube holes 111 on the rectifying plate 11 are arranged at equilateral triangle intervals, that is, any three adjacent tube holes 111 are respectively located at the three vertices of an equilateral triangle. A gas hole 112 passing through the rectifying plate 11 is provided at the central position between any three adjacent tube holes 111. That is, the distances from the centers of any three adjacent tube holes 111 to the center of the corresponding gas hole 112 are equal, so that a plurality of rows of gas holes are formed on the rectifying plate 11 and are arranged in sequence along an air inlet direction. The axes of the gas holes 112 are parallel to the axes of the tube holes 111, and this air inlet direction is perpendicular to the support tubes 13. The diameters of the gas holes 112 in the same row of gas holes are equal, and the diameters of the plurality of rows of gas holes increase along the air inlet direction.

[0032] The filtering component 1 of the present invention is applicable to a horizontal filtering separator. In the horizontal filtering separator, the area where the plurality of support tubes 13 are located is the tube bundle area, and the area where the plurality of filter elements 12 are located is the filter element area. The filtering separator has an air inlet 21, and the air inlet 21 allows gas (such as natural gas) to flow into the tube bundle area along the air inlet direction. Since the diameters of the plurality of rows of gas holes 112 increase along the air inlet direction, that is, the diameter of the row of gas holes closest to the air inlet 21 is the smallest, and the diameter of the row of gas holes farthest from the air inlet 21 is the largest. When in use, the horizontal filtering separator is placed horizontally, so the air inlet direction is usually the vertically downward direction.

[0033] When filtering gas by using a horizontal filtering separator, the working principle is as follows:

[0034] Please refer to Figure 1 and Figure 2, the gas flows from the air inlet 21 along the air inlet direction (e.g., the vertically downward direction) into the tube bundle area. The gas is blocked by the support tubes 13 in the tube bundle area and changes its flow direction. The direction changes from the air inlet direction perpendicular to the support tubes 13 to the direction parallel to the support tubes 13 (i.e., the horizontal direction). At the same time, multiple support tubes 13 exert a blocking effect on the gas to form resistance. The flow resistance of the multiple support tubes 13 to the gas is proportional to the distance that the gas flows along the air inlet direction. That is, when the gas flows from the upper tube bundle near the air inlet 21 to the lower tube bundle away from the air inlet 21, the flow resistance of the gas in the upper tube bundle area near the air inlet 21 is smaller, and the flow resistance in the lower tube bundle area away from the air inlet 21 is larger. According to the gas flow equation, compared with the area with smaller flow resistance, the flow velocity of the gas in the area with larger flow resistance will decrease, and the flow rate will decrease. As a result, the gas flow velocity is larger in the tube bundle area near the air inlet 21, and the gas flow velocity is smaller in the tube bundle area away from the air inlet 21. When the gas passes through the rectifying plate 11, the gas with a larger flow velocity passes through the air holes 112 with a smaller aperture and is subject to a larger resistance from the air holes 112, while the gas with a smaller flow velocity passes through the air holes 112 with a larger aperture and is subject to a smaller resistance from the air holes 112. According to the gas flow equation, the momentum of the gas before and after passing through the air holes 112 should be conserved, that is, the gas flow will balance the vector difference of the gas flow velocities at each air hole 112, so that the horizontal component quantities of the gas flow velocity vectors passing through each air hole 112 of the rectifying plate 11 are all equal, achieving the gas momentum balance at each air hole 112. The gas flow distribution in the filter element area is relatively uniform after the gas passes through each air hole 112, and the gas flow velocities entering each filter element 12 are relatively uniform, and the gas treatment capacities of each filter element 12 are basically equal; when the gas in the filter element area passes through the side walls of multiple filter elements 12 and enters the inside of the filter element 12, dust and other impurities in the gas are filtered by the outer surface of the filter element 12, and a part of the liquid droplets in the gas coalesce inside the filter element 12 after entering the filter element 12, and the coalesced liquid droplets are discharged from the outer surface of the filter element 12 due to the action of gravity.

[0035] By providing the rectifying plate 11, the air holes 112 with different apertures on the rectifying plate 11 can rectify the gas with uneven gas velocity distribution, effectively improve the problem of uneven gas distribution flowing into multiple filter elements 12, extend the service life of the filter elements 12, reduce the replacement frequency of the filter elements 12, and lower the production cost.

[0036] In addition, since the distance between the center of each air hole 112 and the centers of the three surrounding tube holes 111 is equal, it can ensure that the gas flow velocities of the gas flowing into the three adjacent filter elements 12 after being rectified by any air hole 112 are the same, and the velocity components pointing to the center of the circle at each angle in the circumferential direction of the filter element 12 are equal, and no unbalanced impact load will be generated on the filter element 12.

[0037] In addition, by arranging a plurality of tube holes 111 at equal intervals, a plurality of filter elements 12 are evenly distributed at equal intervals. The distance between each filter element 12 and the three surrounding filter elements 12 is equal. This not only effectively utilizes the space inside the separator, but also enables the filter elements 12 to fully contact the gas, ensuring that the velocity components of the outer surface of each filter element 12 pointing to the center of the filter element 12 at various angles in the circumferential direction are equal.

[0038] The filter element 12 in the present invention is a filtration and separation filter element, which is formed by orderly winding filtration materials such as glass fiber and metal fiber layer by layer around a cylindrical metal skeleton and fixing them. Its outer surface is used for filtering dust, and the internal liquid droplets are filtered and separated through coalescence. The filter element 12 adopted in the present invention is an existing filter element, so its specific structure will not be described in detail.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, further, the rectifying plate 11 has a center, and a tube hole 111 is provided at the center. The remaining tube holes 111 are arranged around the center to form a circle of tube holes or multiple circles of tube holes that are sequentially spaced apart from the inside to the outside. The nth circle of tube holes is composed of 6n tube holes 111 arranged at equal intervals in a regular hexagon. That is, the first circle of tube holes is composed of six tube holes 111, and these six tube holes 111 are distributed at the six vertices of the regular hexagon. The second circle of tube holes is composed of twelve tube holes 111, and these twelve tube holes 111 are distributed at the six vertices and the centers of the six sides of the regular hexagon.

[0041] As Figure 2 shown, further, multiple circles of tube holes 111 are arranged around the outside of the center. Except for the outermost circle of tube holes 111, each of the remaining tube holes 111 is surrounded by six air holes 112 arranged at equal intervals in a circular ring. In the Figure 2 example, the aperture of one air hole 112 directly above the tube hole 111 among these six air holes 112 is r1, the aperture of one air hole 112 in the upper left of the tube hole 111 is r2, the aperture of one air hole 112 in the upper right of the tube hole 111 is r3, the aperture of one air hole 112 in the lower left of the tube hole 111 is r4, the aperture of one air hole 112 in the lower right of the tube hole 111 is r5, and the aperture of one air hole 112 directly below the tube hole 111 is r6. Among them, r2 = r3, r4 = r5, and r1 < r2 < r4 < r6.

[0042] In order to ensure the support strength of the rectifying plate 11 for the support tube 13, there should be a certain interval between the air holes 112 and the tube holes 111, and they should not be connected.

[0043] As Figure 2As shown, further, the air holes 112 in the same exhaust hole are arranged at equal intervals in a straight line direction in sequence. This straight line direction is perpendicular to the air inlet direction and perpendicular to the support pipe 13. The diameters of the air holes 112 in the same exhaust hole are equal. When the air inlet direction is the vertical direction, this straight line direction is the horizontal direction. In Figure 2 the example of, this straight line direction is the horizontal direction from left to right.

[0044] Further, the increase amount of the diameter of the multiple exhaust holes along the air inlet direction is proportional to the increase amount of the straight-line distance of the multiple exhaust holes along the air inlet direction and satisfies a linear relationship. Specifically, as Figure 2 shown, let the diameter of a certain exhaust hole be R, and the straight-line distance of this exhaust hole to the air inlet 21 along the air inlet direction be L. R and L satisfy the relationship: R = kL + b, where k and b are constants.

[0045] Further, the minimum diameter of the air hole 112 is not less than 1 / 10 of the diameter of the support pipe 13 to prevent throttling phenomenon when gas passes through the air hole 112 with a smaller diameter.

[0046] Embodiment 3

[0047] On the basis of Embodiment 1 and Embodiment 2, even further, the inventor also found in the research that when gas enters the tube bundle area in the prior art, during the process of changing the air flow direction, the liquid droplets carried by the gas include those with larger mass and smaller mass. The liquid droplets with larger mass, due to having larger inertial forces, will collide with the surface of the support pipe 13 and the bottom wall surface of the separator tank body and be intercepted. Among them, the liquid droplets that collide with the bottom of the tank body will flow along the bottom of the tank body under the action of the air flow because the bottom of the tank body is approximately a plane relative to the liquid droplets, and are likely to enter the liquid collection port of the liquid collection bag 7 at the bottom of the cylinder body 1 and finally be discharged from the liquid discharge port 71; while the liquid droplets that collide with the surface of the support pipe 13 will fall off from the surface of the support pipe 13 under the action of the air flow and be wrapped by the gas again and enter the filter element 12 because the surface of the support pipe 13 has no affinity for the liquid droplets and the contact angle is greater than 90° (as Figure 4 shown). The liquid droplets with smaller mass have smaller inertial forces and can follow the air flow to change the flow direction and are not easy to hit the bottom wall surface of the cylinder body 1. They are only blocked by the tube bundle of the support pipe 13 and cannot be captured by the metal surface of the support pipe 13 when hitting the surface of the tube bundle of the support pipe 13, and will quickly return to the air flow again and enter the filter element 12 (as Figure 4 shown). Therefore, by using the inertial separation effect of changing the air flow direction to pre-separate the liquid droplets entrained in the gas, the effect is not obvious for the liquid droplets with smaller mass and the liquid droplets with larger mass that collide with the surface of the support pipe 13.

[0048] To solve the technical problem that "for the inertial separation by changing the air flow direction to pre-separate the droplets entrained in the gas, the effect is not obvious for the droplets with smaller mass and the droplets with larger mass that collide with the surface of the support tube 13", the inventor has made further improvements to the support tube 13: as Figure 5 shown, an oleophilic layer 131 is provided on the outer surface of each support tube 13, and the oleophilic layer 131 makes the support tube 13 have super-oleophilic or super-hydrophobic properties.

[0049] Since the oleophilic layer 131 has oleophilic characteristics, the contact angle of the droplet Q in contact with the outer surface of the support tube 13 is less than 90° and it is difficult to fall off from the outer surface. When the droplet Q in the gas passes through the gap area of the support tube 13 along with the air flow, a part of the droplet Q collides with the support tube 13 by inertia in the air flow direction and is then captured by the oleophilic layer 131, as Figure 5 shown, the captured droplet Q continuously coalesces and grows on the surface of the support tube 13. When the particles of the captured droplet Q converge and grow to a certain volume, they break away from the support tube 13 under the action of gravity and air flow, drip onto the bottom wall surface of the cylinder 1 and then enter the liquid accumulation package, completing the pre-separation function. Therefore, the support tube 13 with the oleophilic layer 131 has a better capture effect on the droplet Q in the gas, and has a higher pre-separation efficiency compared with the support tube 13 without the oleophilic layer 131.

[0050] Among them, the support tube 13 is a metal tube, and the oleophilic layer 131 can be obtained by metal surface treatment of the support tube 13, such as soaking in an ethanol solution of stearic acid and hydrochloric acid, or it can also be a candle ash coating.

[0051] In this embodiment, by providing the oleophilic layer 131 on the outer surface of the support tube 13, the pre-separation effect of the tube bundle area on the droplets entrained in the gas is enhanced, the overall performance efficiency of the equipment is improved, and the filtering and separating ability of the equipment for the droplets in the gas is improved.

[0052] Embodiment 4

[0053] On the basis of Embodiment 3, the present invention further provides a horizontal filter separator, which includes a cylinder 2 and a filter assembly arranged in the cylinder 2. The filter assembly is the filter assembly 1 in Embodiments 1, 2, and 3. The axial directions of each filter element 12 and each support tube 13 are all parallel to the axial direction of the cylinder 2. The rectifying plate 11 is perpendicular to the axial direction of the cylinder 2 and is fixedly connected to the cylinder 2. An air inlet 21 is provided on the side wall of the cylinder 2. The air inlet 21 and the support tube 13 are on the same side of the rectifying plate 11, and the air inlet 21 is directly opposite to the support tube 13. Among the multiple rows of air holes on the rectifying plate 11, the row of air holes with the smallest aperture is the closest to the air inlet 21, and the row of air holes with the largest aperture is the farthest from the air inlet 21.

[0054] Specifically, the cylinder body 2 of the horizontal filter separator is placed horizontally, the axial direction of the cylinder body 2 is the horizontal direction, the air inlet 21 is located at the top of the cylinder body 2, and the air inlet direction is vertically downward.

[0055] The filter components in this embodiment are the same as those of the filter component 1 in Embodiments 1, 2, and 3 in terms of structure, working principle, and beneficial effects, and will not be elaborated here.

[0056] The horizontal filter separator of the present invention can effectively improve the problem of uneven gas distribution flowing into multiple filter elements, extend the service life of the filter elements, reduce the replacement frequency of the filter elements, and lower the production cost.

[0057] As Figure 1 shown, in one embodiment, a partition plate 3 is provided inside the cylinder body 2. The partition plate 3 is arranged perpendicular to the axial direction of the cylinder body 2 and divides the interior of the cylinder body 2 into a primary filtration chamber 22 and a secondary filtration chamber 23. The filter component 1 is arranged in the primary filtration chamber 22 for realizing the first-stage filtration and separation. A plurality of support tubes 13 are respectively fixedly connected to the partition plate 3, that is, the rectifying plate 11 and the partition plate 3 respectively fixedly support the opposite ends of the support tube 13. A secondary filtration element 4 is provided in the secondary filtration chamber 23. An air outlet 24 communicating with the secondary filtration chamber 23 is also provided on the cylinder body 2. The filter element 12, the rectifying plate 11, the support tube 13, the partition plate 3, the secondary filtration element 4, and the air outlet 24 are arranged in sequence along the axial direction of the cylinder body 2. The secondary filtration element 4 in this embodiment is an existing filter element capable of filtering liquid droplets.

[0058] The working principle of this embodiment is as follows: The gas enters the tube bundle area from the air inlet 21 and impacts on the support tube 13. At the same time, the flow direction of the gas changes from the vertical direction to the horizontal direction, and then passes through the rectifying plate 11. After being rectified by the air holes 112 of the rectifying plate 11, it enters the filter element area. When the gas passes through the filter element 12, the dust in the gas is filtered by the outer surface of the filter element 12. Some of the liquid droplets in the gas coalesce inside the filter element 12 and are discharged from the outer surface of the filter element 12 due to gravity and drip to the bottom of the cylinder body 2. The other part of the liquid droplets follows the gas through the internal space of the support tube 13, passes through the support tube 13 and enters the secondary filtration chamber 23, and after being separated by the secondary filtration element 4, settles to the bottom of the cylinder body 2. The purified gas is discharged from the air outlet 24.

[0059] Furthermore, as Figure 1 shown, in order to facilitate the replacement of the filter element 12, one end of the cylinder body 2 close to the filter element 12 is set as an open end, and a quick-opening blind plate 5 is provided at this open end. The quick-opening blind plate 5 is detachably connected to the cylinder body 2. When the filter element 12 needs to be replaced, the quick-opening blind plate 5 can be opened to take out the filter element 12. In order to make it easy to separate the filter element 12 from the support tube 13, the filter element 12 and the support tube 13 can be connected by a tightly inserted connection method, which not only realizes the sealed connection between the two but also facilitates disassembly and assembly.

[0060] Furthermore, as Figure 1 shown, a pressing plate 6 is further provided inside the cylinder body 2. The pressing plate 6 is arranged adjacent to the quick-opening blind plate 5. Both ends of each filter element 12 are respectively connected to the support pipe 13 and the pressing plate 6. Therefore, the pressing plate 6 and the support pipe 13 jointly support the filter element 12.

[0061] In one embodiment, as Figure 1 shown, a liquid collection bag 7 is provided outside the cylinder body 2. The liquid collection bag 7 is communicated with the primary filtration chamber 22 and the secondary filtration chamber 23. A liquid discharge port 71 is provided on the liquid collection bag 7. Specifically, the liquid collection bag 7 is located below the horizontally placed cylinder body 2. The connection part between the liquid collection bag 7 and the cylinder body 2 is located at the bottom of the cylinder body 2.
