Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a spherical filler and waste gas treatment equipment. Background Art

[0002] The key process of waste gas biological oxidation treatment technology is interphase mass transfer, that is, pollutants in the gas (such as volatile organic compounds) will come into contact with microorganisms in the water through the gas-liquid interface, and be degraded and converted into harmless substances under the action of microorganisms.

[0003] However, the gas-liquid contact in the packing structure in the prior art is insufficient, and the mass transfer efficiency is low, so that the exhaust gas purification efficiency is relatively low. Utility Model Content

[0004] The utility model aims to provide a spherical filler and waste gas treatment equipment, which can improve the mass transfer efficiency and thus improve the purification efficiency.

[0005] The embodiment of the utility model is achieved as follows:

[0006] In a first aspect, the utility model provides a spherical filler, comprising:

[0007] The first hemisphere, the second hemisphere and the outer ring are located on the same sphere, and the first hemisphere and the second hemisphere are connected by the outer ring;

[0008] The first hemisphere includes a plurality of first arcuate ribs spaced apart along the circumferential direction, and one end of all the first arcuate ribs is connected to the outer circular ring, and the other end is arched inwardly; the second hemisphere includes a plurality of second arcuate ribs spaced apart along the circumferential direction, and one end of all the second arcuate ribs is connected to the outer circular ring, and the other end is arched inwardly, and at least one first arcuate rib is a first torsion rib.

[0009] Based on the above configuration, the barrier equivalent is greatly reduced, the porosity is increased, and the specific surface area is increased, thereby improving the mass transfer efficiency and purification efficiency. In addition, the configuration of the first torsion rib not only provides additional contact points for the gas and liquid flowing along it, thereby improving the purification efficiency, but also helps to guide the gas through the sphere, simplifying the diffusion path of the gas and liquid between the spherical fillers, and further reducing the mass transfer resistance.

[0010] In an optional embodiment, at least one second arc-shaped rib is a second torsion rib and / or the outer circular ring is in the shape of a torsion rib.

[0011] Based on the above arrangement, when the fluid enters the spherical packing through the second torsion rib and / or the outer ring, the torsion structure of the two can also increase the gas-liquid mass exchange edge area and provide a guide path for the fluid to increase the mass transfer efficiency. In an optional embodiment, the maximum torsion angle of the first torsion rib and / or the second torsion rib is greater than ninety degrees.

[0012] Based on the above settings, when the water droplets are accelerated through the maximum rotation angle of the torsion ribs, the residence time is reduced, that is, the time the water droplets occupy the surface area of ​​the spherical filler is reduced, the liquid with a purifying effect is quickly renewed, and the gas-liquid-mass exchange efficiency is improved.

[0013] In an optional embodiment, all first arc-shaped ribs are first torsion ribs, and all second arc-shaped ribs are second torsion ribs.

[0014] Based on the above arrangement, the mass transfer efficiency of the spherical filler is improved overall.

[0015] In an optional embodiment, the number of the first torsion ribs corresponds to the number of the second torsion ribs one-to-one, and the torsion directions of all the first torsion ribs are the same, and the torsion directions of all the second torsion ribs are the same.

[0016] Based on the above configuration, it is ensured that the first torsion ribs in the first hemisphere produce a consistent guiding path for the fluid, avoiding the adjacent first torsion ribs interfering with the fluid flow direction, causing turbulence and affecting the mass transfer efficiency. It is understandable that the second torsion ribs with the same direction in the second hemisphere are similar to the above, and can also avoid the occurrence of turbulence.

[0017] In an optional embodiment, the spherical filler further includes a plurality of support ribs, one end of the support rib is connected to the first torsion rib, and the other end of the support rib is connected to the adjacent second torsion rib.

[0018] Based on the above arrangement, the stability of the overall structure of the spherical material is improved.

[0019] In an optional embodiment, the spherical filler also includes a plurality of connecting plates and connecting pieces connected to the ends of any two adjacent connecting plates, and the connecting plates and the connecting pieces together surround a shaft member coaxial with the outer ring; any one of the connecting plates is connected to a fixed number of first arc-shaped ribs away from one end of the outer ring; and any one of the connecting pieces is connected to a fixed number of second arc-shaped ribs away from one end of the outer ring.

[0020] Based on the above arrangement, it is convenient for the first arcuate ribs and the second arcuate ribs to be fixed to the connecting plate and the connecting member respectively during the extension process, so as to reduce the entanglement or interference of adjacent first arcuate ribs or adjacent second arcuate ribs.

[0021] In an optional embodiment, the spherical filler further includes a fixing ring coaxial with the outer circular ring, the fixing ring is located in the inner cavity of the shaft and is connected to one end of all the connecting plates away from the connecting member.

[0022] Based on the above arrangement, the stability of the spherical filler structure is improved, and the end of the connecting plate away from the connecting piece is prevented from collapsing inward, affecting the spatial structural arrangement of the first arcuate rib and further affecting the effect of the first arcuate rib.

[0023] In an optional embodiment, a first reinforcing rib is provided between two first arc-shaped ribs connected to the same connecting plate, and a second reinforcing rib is provided between two second arc-shaped ribs connected to the same connecting member.

[0024] Based on the above arrangement, the mechanical strength of the first arc-shaped rib and the second arc-shaped rib is respectively increased, thereby resisting the deformation of the spherical filler during stacking or placing.

[0025] In a second aspect, the utility model provides an exhaust gas treatment device, comprising the spherical filler of any one of the aforementioned embodiments.

[0026] Based on the above configuration, it includes the spherical filler in the above embodiment. Therefore, the waste gas treatment equipment also increases the edge area of ​​gas-liquid mass exchange, provides additional contact points for the gas and liquid flowing along the first arc rib, and improves the purification efficiency without affecting the volume and porosity of the spherical filler; and, through the twisting of the rib, its cross-sectional area can also be not increased, so that its blocking equivalent diameter for gas remains unchanged. In addition, the setting of the twisted rib is also conducive to guiding the gas through the sphere, simplifying the diffusion path of gas and liquid between the spherical fillers, and further reducing the mass transfer resistance.

[0039] Figure 1 This is a first perspective schematic diagram of the spherical filler 10 provided in the embodiment of the utility model, please refer to Figure 1 The present application provides a spherical filler 10 , which includes a first hemisphere 100 , a second hemisphere 300 , and an outer ring 500 located in the same sphere, and the first hemisphere 100 and the second hemisphere 300 are connected by the outer ring 500 .

[0040] Among them, the first hemisphere 100 includes a plurality of first arcuate ribs 110 arranged at intervals along the circumferential direction, and one end of all the first arcuate ribs 110 is connected to the outer ring 500, and the other end is arched inwardly; the second hemisphere 300 includes a plurality of second arcuate ribs 310 arranged at intervals along the circumferential direction, and one end of all the second arcuate ribs 310 is connected to the outer ring 500, and the other end is arched inwardly, and at least one first arcuate rib 110 is a first torsion rib.

[0041] It can be understood that the first hemisphere 100 and the second hemisphere 300 are connected by the outer ring 500, and the three together form a sphere, and the first arc rib 110 and the second arc rib 310 are both quarter spherical arcs on the sphere. Through the above structural setting, the blocking equivalent is greatly reduced, the porosity is increased, and the specific surface area is increased, thereby improving the mass transfer efficiency and purification efficiency.

[0042] On this basis, at least one first arcuate rib 110 is provided as a first torsion rib. On the one hand, the torsion structure of the first arcuate rib 110 increases the specific surface area, and the surface area of ​​the spherical filler 10 is increased while the volume and porosity remain unchanged, thereby increasing the edge area of ​​gas-liquid mass exchange, providing additional contact points for the gas and liquid flowing along it, and improving the purification efficiency without affecting the volume and porosity of the spherical filler 10; on the other hand, the torsion of the rib may not increase its cross-sectional area, so that its blocking equivalent diameter for gas remains unchanged, that is, its resistance to gas is not changed, which is also conducive to guiding the gas through the sphere, simplifying the diffusion path of gas and liquid between the spherical fillers 10, and further reducing the mass transfer resistance.

[0043] Furthermore, in order to guide the gas or liquid through the spherical packing 10 in multiple directions, at least one second arcuate rib 310 is a second twist rib and / or the outer ring 500 is formed into a twist rib shape. In other words, at least one second arcuate rib 310 is a second twist rib, or the outer ring 500 is formed into a twist rib structure, or at least one second arcuate rib 310 is formed into a second twist rib and the outer ring 500 is formed into a twist rib structure. Based on this, when the fluid enters the spherical packing 10 through the second twist rib and / or the outer ring 500, the twist structures of the above two can also increase the gas-liquid mass exchange edge area, and provide a guiding path for the fluid, thereby increasing the mass transfer efficiency.

[0044] It should be noted that the first torsion rib, the second torsion rib and the torsion rib structure of the outer ring in the present application can be deformed along their own extension direction and circumferential rotation to form a linear spiral structure, thereby relatively increasing their specific surface area.

[0045] Considering that liquid film is easily formed during the purification process, which slows down the diffusion efficiency of the gas, the maximum torsion angle of the first torsion rib and / or the second torsion rib is greater than ninety degrees. Based on the above configuration, when water droplets pass through the maximum rotation angle of the torsion rib, it is not easy for the water droplets to stay or accumulate to form a wall-hanging water film, but accelerate through the place, reducing the residence time, that is, reducing the time that the water droplets occupy the surface area of ​​the spherical filler 10, quickly renewing the liquid with purification effect, and improving the gas-liquid-mass exchange efficiency.

[0046] Considering that when the spherical filler 10 is used, the flow direction of the gas and liquid varies with the stacking method. In order to avoid excessive flow rate difference between the two resulting in insufficient mass transfer, the torsion angles of the first torsion rib and the second torsion rib are repeatedly changed at the same frequency, that is, the torsion angle and the torsion period are the same.

[0047] In order to improve the mass transfer efficiency of the spherical packing 10 as a whole, all the first arc-shaped ribs 110 are first torsion ribs, and all the second arc-shaped ribs 310 are second torsion ribs. Based on this, when the fluid enters the spherical packing 10 through the first hemisphere 100 or the second hemisphere 300, it is affected by the torsion structure, thereby improving the mass transfer efficiency and purification efficiency.

[0048] In addition, to ensure the consistency of the guide paths in the first hemisphere 100 and the second hemisphere 300, the number of first torsion ribs corresponds to the number of second torsion ribs, and the torsion directions of all first torsion ribs are the same, and the torsion directions of all second torsion ribs are the same.

[0049] Based on this, it is ensured that the first torsion ribs in the first hemisphere 100 produce a consistent guiding path for the fluid, avoiding the adjacent first torsion ribs interfering with the fluid flow direction, causing turbulence and affecting the mass transfer efficiency. It is understandable that the second torsion ribs with the same direction in the second hemisphere 300 are similar to the above, and can also avoid the occurrence of turbulence, which will not be repeated here.

[0050] Optionally, any first torsion rib is staggered with the adjacent second torsion rib to reduce stress concentration at the connection of the outer ring 500 and improve the bearing capacity of the connection of the outer ring 500. Further, in order to improve the stability of the overall structure of the spherical material, the spherical filler 10 also includes a plurality of support ribs 400, one end of the support rib 400 is connected to the first torsion rib, and the other end is connected to the adjacent second torsion rib. It can be understood that the number of the first torsion rib, the second torsion rib and the support rib 400 is the same.

[0051] See also Figure 2 and Figure 3 Considering that the first arc ribs 110 and the second arc ribs 310 may be entangled at one end away from the outer ring 500, the spherical filler 10 also includes a plurality of connecting plates 710 and connecting pieces 730 connected to the ends of any two adjacent connecting plates 710, and the connecting plates 710 and the connecting pieces 730 are together formed around a shaft coaxial with the outer ring 500; any one of the connecting plates 710 is connected to one end of a fixed number of the first arc ribs 110 away from the outer ring 500; and any one of the connecting pieces 730 is connected to one end of a fixed number of the second arc ribs 310 away from the outer ring 500.

[0052] It can be understood that the first arc rib 110 and the second arc rib 310 extend and converge at two opposite vertices of the sphere respectively. By arranging a shaft coaxial with the outer ring 500 between the spherical filler 10, it is convenient for the first arc rib 110 and the second arc rib 310 to be fixed to the connecting plate 710 and the connecting member 730 respectively during the extension process, so as to reduce the entanglement or interference of adjacent first arc ribs 110 or adjacent second arc ribs 310.

[0053] Furthermore, it can be understood that, due to the arrangement of the connecting member 730 being connected to the end plates of any two adjacent connecting plates 710, the first arcuate rib 110 and the second arcuate rib 310 are arranged as follows: Figure 4 The staggered arrangement in the perspective shown fully improves the space utilization of the sphere where the spherical filler 10 is located, and improves the mass transfer efficiency when the gas and liquid flow through. In addition, a connecting plate 710 can be connected to one or two first arc-shaped ribs 110, and a connecting piece 730 can be connected to one or two second arc-shaped ribs 310. Preferably, the number of connecting plates 710 and connecting pieces 730 is 4 respectively, so as to realize the resistance of the shape of the spherical filler 10 and provide a larger surface area at the same time.

[0054] In order to better resist the deformation of the spherical fillers 10 during stacking or placement, a first reinforcing rib 150 is provided between two first arcuate ribs 110 connected to the same connecting plate 710, and a second reinforcing rib 350 is provided between two second arcuate ribs 310 connected to the same connecting member 730. Based on the provision of the first reinforcing rib 150 and the second reinforcing rib 350, the mechanical strength of the first arcuate rib 110 and the second arcuate rib 310 is increased respectively, thereby achieving resistance to deformation.

[0055] Further, please refer again to Figure 1 In order to achieve gas-liquid path guidance while resisting deformation, the first reinforcing rib 150 and the second reinforcing rib 350 are both V-shaped structures with the tip facing the outer ring 500. It can be understood that the first reinforcing rib 150 and the second reinforcing rib 350 of the V-shaped structure with the tip facing the outer ring 500 can guide the gas or liquid to pass through the surface of the spherical packing 10, thereby reducing the resistance coefficient of the spherical packing 10 and improving the mass transfer efficiency of the spherical packing 10.

[0056] In addition, it should be noted that, since the connection plate 710 and the connection member 730 are staggered, the first reinforcing rib 150 and the second reinforcing rib 350 are also staggered. Based on this, the V-shaped structure will not cause turbulence of gas and liquid at the outer ring 500.

[0057] Please refer again Figure 3 In order to improve the stability of the spherical filler 10 structure, the spherical filler 10 further includes a fixing ring 750 coaxial with the outer ring 500. The fixing ring 750 is located in the inner cavity of the shaft and connected to the end of all the connecting plates 710 away from the connecting member 730. Through the above arrangement, it is prevented that the end of the connecting plate 710 away from the connecting member 730 collapses inwards, affecting the spatial structure arrangement of the first arc rib 110, and further affecting the effect of the first arc rib 110.

[0058] In summary, the utility model provides a spherical filler 10, which includes a first hemisphere 100, a second hemisphere 300 and an outer ring 500 located in the same sphere. Among them, the first hemisphere 100 includes a plurality of first arcuate ribs 110, the second hemisphere 300 includes a plurality of second arcuate ribs 310, and at least one first arcuate rib 110 is a first torsion rib. Based on the setting of the above-mentioned first torsion rib, on the one hand, the torsion structure increases the specific surface area, and increases the surface area of ​​the spherical filler 10 under the condition that the volume and porosity remain unchanged, thereby increasing the gas-liquid mass exchange edge area, providing additional contact points for the gas and liquid flowing along it, and improving the purification efficiency without affecting the volume and porosity of the spherical filler 10; on the other hand, the torsion of the ribs can also not increase its cross-sectional area, so that its blocking equivalent diameter to the gas remains unchanged, that is, it does not change its resistance to the gas, and it is also conducive to guiding the gas through the sphere, simplifying the diffusion path of the gas and liquid between the spherical fillers 10, and further reducing the mass transfer resistance.

[0059] In addition, the utility model also provides a waste gas treatment device, which includes the spherical filler 10 in the above-mentioned embodiment. Therefore, the waste gas treatment device also increases the edge area of ​​gas-liquid mass exchange, provides additional contact points for the gas and liquid flowing along the first arc rib 110, and improves the purification efficiency without affecting the volume and porosity of the spherical filler 10; and, through the twisting of the rib, its cross-sectional area can also be not increased, so that its blocking equivalent diameter for gas remains unchanged. In addition, the setting of the twisted rib is also conducive to guiding the gas through the sphere, simplifying the diffusion path of gas and liquid between the spherical fillers 10, further reducing the mass transfer resistance, and improving the purification effect of the waste gas treatment equipment.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
