Description

Technical Field

[0001] The present invention belongs to the technical field of oil-water separation, and in particular relates to an oil-water separation spherical grid layer, a spherical grid type oil-water separation structural component and an oil-water separator. Background Art

[0002] Oily wastewater is widely found in industries such as petrochemicals, machinery manufacturing, food processing, and shipping. Its composition is complex and the oil phase is highly dispersed. Discharged directly without treatment not only results in a significant waste of oil resources but also causes environmental pollution. Therefore, efficient oil-water separation is a crucial process in industrial water treatment applications.

[0003] Oil-water separators are widely used devices in oily wastewater treatment. A typical oil-water separator consists of a tank, liquid inlet and outlet ports, an inlet distributor, a cohesive structure, and baffles. The cohesive structure is the core component of oil-water separation, and its performance directly determines the effectiveness of the separation. The cohesive structure works by promoting the collision and coalescence of dispersed oil droplets, which, under the action of gravity, achieves efficient separation of the oil and water phases.

[0004] Currently, commonly used aggregate structures mainly include wire mesh, corrugated plate, and packing. Among them, wire mesh aggregate structures use multiple layers of metal wire mesh to aggregate dispersed oil droplets. The small diameter of the metal wires is not conducive to the adhesion of small oil droplets, and the narrow flow channel is easily blocked by impurities such as suspended solids. The structure of corrugated plate aggregate structures can improve the degree of fluid deflection and the collision frequency of dispersed oil droplets to a certain extent. However, the oil droplets collide with the plate at a certain angle, which is prone to slippage, and the oil droplet capture effect is poor. Packing aggregate structures use the slit effect to achieve efficient collision capture of dispersed oil droplets, and the oil-water separation effect is better. However, due to the small gap in the packing, impurities such as oil droplets or small particles in sewage are easily blocked in the packing layer, requiring frequent backwashing for regeneration. The regeneration difficulty and use cost are high.

[0005] It can be seen that efficient coalescence of dispersed oil droplets and prevention of impurity clogging are two key issues that need to be solved in high-performance oil-water separation polymer components. Summary of the Invention

[0006] The main purpose of the present invention is to propose an oil-water separation spherical grid layer, a spherical grid type oil-water separation structure and an oil-water separator, aiming to solve the technical problems of poor oil-water separation effect and easy clogging of the oil-water separation device in the prior art.

[0007] To achieve the above object, the present invention provides an oil-water separation ball grid layer for oil-water separation. The oil-water separation ball grid layer includes: a connecting pipe, the axial direction of the connecting pipe is the first direction, and the first direction is perpendicular to the water flow direction. A plurality of the connecting pipes are arranged in parallel in sequence along the second direction, the second direction is perpendicular to the water flow direction, and a first anti-blocking gap is provided between any two adjacent connecting pipes; a collision ball, a through hole for the connecting pipe to pass through is opened along the radial direction of the collision ball, the inner diameter size of the through hole matches the outer diameter size of the connecting pipe, the number of the collision balls is plural, the connecting pipes sequentially pass through a plurality of the collision balls and are connected to the collision balls, and a second anti-blocking gap is provided between any two adjacent collision balls. The first anti-blocking gap is larger than the outer diameter of the collision ball, and any four adjacent collision balls enclose a converging space.

[0008] In an embodiment of the present invention, the length of the second anti-blocking gap is L1, the outer diameter of the collision ball is d, and L1 = a*d, where a is 1.2 - 1.5.

[0009] In an embodiment of the present invention, the collision ball is a hollow ball, and the outer diameter of the collision ball is 10 mm - 50 mm.

[0010] In an embodiment of the present invention, any four adjacent collision balls are arranged in a rectangular or rhombic manner, and the collision balls are respectively located at the four vertices of the rectangle or rhombus.

[0011] In an embodiment of the present invention, the connecting pipe is a hollow pipe with a hollow cavity, and the hollow cavity is used to accommodate a heating element.

[0012] The present invention also proposes a ball grid type oil-water separation and aggregation structural member, which includes the oil-water separation ball grid layer as described above, and multiple layers of the oil-water separation ball grid layer are arranged in parallel in sequence along the water flow direction.

[0013] In an embodiment of the present invention, any two adjacent oil-water separation ball grid layers are arranged in a staggered distribution, and the center of the ball of the collision ball in the lower oil-water separation ball grid layer is aligned with the center of the converging space of the upper oil-water separation ball grid layer.

[0014] In an embodiment of the present invention, an anti-blocking channel is provided between any two adjacent oil-water separation ball grid layers.

[0015] In an embodiment of the present invention, the length of the anti-blocking channel is L2, the outer diameter of the collision ball is d, and L2 = b*d, where b is 0.8 - 2.2.

[0016] The present invention also proposes an oil-water separator, which includes a fixing plate and the above-mentioned ball grid type oil-water separation and aggregation structural member, and both ends of the connecting pipe along the axial direction are connected to the fixing plate.

[0017] Through the above technical solution, the oil-water separation ball grid layer provided by the embodiment of the present invention has the following beneficial effects:

[0018] For the oil-water separation ball grid layer, by arranging a plurality of collision balls on each connecting pipe, the flow deflection direction of the fluid is orderly changed, the collision probability between the oil droplets and the spherical surface is increased, and the coalescence residence time of the oil droplets is increased by using the high specific surface area of the collision balls. At the same time, a first anti-blocking gap is provided in the second direction, and a second anti-blocking gap is provided in the first direction, so that blockage of the oil-water separation ball grid layer by impurities can be avoided in the first direction and the second direction.

[0027] DESCRIPTION OF THE REFERENCE NUMERALS

[0028] Detailed implementation manners

[0029] The following describes in detail specific embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0030] The following describes an oil-water separation ball grid layer according to the present invention with reference to the accompanying drawings.

[0031] As Figures 1 to 4 shown, in an embodiment of the present invention, the oil-water separation ball grid layer 100 is used for oil-water separation. The oil-water separation ball grid layer 100 includes a connecting pipe 1 and collision balls 2. The connecting pipe 1, the axial direction of the connecting pipe 1 is the first direction, and the first direction is perpendicular to the water flow direction. A plurality of connecting pipes 1 are arranged in parallel in sequence along the second direction. The second direction is perpendicular to the water flow direction, and a first anti-blocking gap 3 is provided between any two adjacent connecting pipes 1; the collision balls 2, a through hole for the connecting pipe 1 to pass through is opened along the radial direction of the collision ball 2. The inner diameter dimension of the through hole matches the outer diameter dimension of the connecting pipe 1. The number of the collision balls 2 is multiple. The connecting pipes 1 sequentially pass through a plurality of collision balls 2 and are connected to the collision balls 2. A second anti-blocking gap 4 is provided between any two adjacent collision balls 2. The first anti-blocking gap 3 is larger than the outer diameter of the collision ball 2, and any four adjacent collision balls 2 enclose a converging space 5.

[0032] It can be understood that the first direction and the second direction in this embodiment can be set according to actual use requirements. As Figure 1 shown, in one embodiment, the first direction is perpendicular to the second direction. The collision balls 2 can be made of stainless steel parts or oil-loving material parts. The collision balls 2 made of stainless steel parts have good structural stability effect, and the collision balls 2 made of oil-loving material parts have better oil-water separation.

[0033] In the oil-water separation ball grid layer 100 of this embodiment, by arranging a plurality of collision balls 2 on each connecting pipe 1, the flow deflection direction of the fluid is orderly changed, the collision probability between the oil droplets and the spherical surface is increased, and the coalescence residence time of the oil droplets is increased by using the high specific surface area of the collision balls 2. The converging space 5 formed by any adjacent four collision balls 2 can effectively guide the confluence of the oil droplets. At the same time, a first anti-blocking gap 3 is arranged in the second direction, and a second anti-blocking gap 4 is arranged in the first direction, which can avoid the blockage of the oil-water separation ball grid layer 100 by impurities in the first direction and the second direction. Moreover, the series structure of the connecting pipe 1 and the collision balls 2 ensures the stability of the oil-water separation ball grid layer 100, is easy to process, and has a low cost. In this embodiment, a plurality of collision balls 2 are orderly connected on each connecting pipe 1, and the oil droplets are effectively converged by the orderly arranged collision balls 2, improving the oil droplet converging effect. At the same time, anti-blocking structures are arranged in both the first direction and the second direction, which can effectively avoid the blockage of the oil-water separation ball grid layer 100 by particulate impurities such as sediment, and can ensure both the oil droplet converging effect and the anti-blocking performance of the oil-water separation ball grid layer 100.

[0034] In one embodiment, the length of the second anti-blocking gap 4 is L1, the outer diameter of the collision ball 2 is d, and L1 = a*d, where a is 1.2 to 1.5. The length of the second anti-blocking gap 3 minus the outer diameter of the collision ball 2 is 0.2 to 1 times the outer diameter of the collision ball 2. A plurality of collision balls 2 are installed on each connecting pipe 1, and the plurality of collision balls 2 are evenly spaced, so that the length of the second anti-blocking gap 4 is 1.2 to 1.5 times the outer diameter of the collision ball 2, which can avoid the situation that the oil droplet converging effect is poor due to the too large second anti-blocking gap 4, and can also avoid the blockage of the oil-water separation ball grid layer 100 caused by the accumulation of particulate matters such as sediment, and can ensure both the oil droplet converging effect and the service life of the oil-water separation ball grid layer 100.

[0035] Specifically, the collision ball 2 is a hollow ball, and the outer diameter of the collision ball 2 is 10 mm to 50 mm. For impurity particles such as sediment in the water flow, the converging effect is better with a ball diameter of 10 mm to 50 mm, providing an effective collision surface area and a better collision effect. In one embodiment, the connecting pipe 1 is a hollow pipe with a hollow cavity, and the hollow cavity is used to accommodate the heating element. For the convenience of connection, the connecting pipe 1 in this embodiment can be a hollow round pipe, and the heating element can be a heating wire. When it is necessary to heat the water flow, the connecting pipe 1 can be heated by supplying power to the heating element, and the collision ball 2 can be heated through the connecting pipe 1 to ensure the adhesion of the oil droplets on the collision ball 2 in a low-temperature environment, thereby improving the converging effect of the oil droplets.

[0036] The present invention also provides a ball grid type oil-water separation and coalescence structural member 200, which includes the above-mentioned oil-water separation ball grid layer 100, and multiple layers of oil-water separation ball grid layers 100 are arranged in parallel in sequence along the water flow direction. The ball grid type oil-water separation and coalescence structural member 200 includes an oil-water separation ball grid layer 100, and the specific structure of this oil-water separation ball grid layer 100 refers to the above-mentioned embodiments. Since the ball grid type oil-water separation and coalescence structural member 200 adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated one by one here.

[0037] As Figure 6 shown, in one embodiment, the ball grid type oil-water separation and coalescence structural member 200 includes four layers of oil-water separation ball grid layers 100, where two oil-water separation ball grid layers 100 are the first oil-water separation layers, and the other two oil-water separation ball grid layers 100 are the second oil-water separation layers. The two first oil-water separation layers and the two second oil-water separation layers are arranged alternately. The connecting pipes 1 on the outermost sides of the two first oil-water separation layers are relatively flush, and the connecting pipes 1 on the outermost sides of the two second oil-water separation layers are relatively flush, so that the connecting pipes 1 in the first oil-water separation layer and the second oil-water separation layer are arranged alternately. The multiple layers of oil-water separation ball grid layers 100 are arranged at intervals in sequence along the water flow direction. The multiple layers of oil-water separation ball grid layers 100 can perform sequential baffle flow on the oil droplets in the water flow, so that the oil droplets are sequentially converged through the converging spaces 5 on the multiple layers of oil-water separation ball grid layers 100. In other embodiments, the number of the oil-water separation ball grid layers 100 can be set according to actual usage requirements.

[0038] As Figure 5 and Figure 6 shown, any two adjacent oil-water separation ball grid layers 100 are arranged in a staggered distribution, and the center of the ball 2 of the lower layer of oil-water separation ball grid layer 100 is aligned with the center of the converging space 5 of the upper layer of oil-water separation ball grid layer 100. In this embodiment, any two adjacent oil-water separation ball grid layers 100 are arranged in a staggered distribution. By arranging the spaces of the multiple layers of balls 2 in an orderly manner in a staggered manner, the baffle flow direction of the fluid is changed orderly, and the collision and coalescence probability of the oil droplets with the spherical surface of the balls 2 is increased; the coalescence residence time of the oil droplets is increased by the high specific surface area of the balls 2. The two effects significantly improve the coalescence effect of the dispersed oil droplets. At the same time, the first anti-blocking gap 3, the second anti-blocking gap 4 and the anti-blocking channel 210 between the balls 2 can prevent the ball grid type oil-water separation and coalescence structural member 200 from being blocked by impurities. When the water flow passes through the multiple layers of oil-water separation ball grid layers 100, the water flow can be converged through the center of the converging space 5. When flowing to the next layer, since the center of the ball 2 of the next layer is aligned with the center of the converging space 5 of the upper layer of oil-water separation ball grid layer 100, the oil droplets can be effectively collided by the balls 2, greatly improving the converging effect of the oil droplets.

[0039] It should be noted that any four adjacent collision balls 2 are arranged in a rectangular or rhombic manner, and the collision balls 2 are respectively located at the four vertices of the rectangle or rhombus. As Figure 3 shown, any four adjacent collision balls 2 are arranged in a rectangular manner, and the center of the convergence space 5 is located at the center of the rectangle. As Figure 4 shown, any four adjacent collision balls 2 are arranged in a rhombic manner, and the center of the convergence space 5 is located at the center of the rhombus. In this embodiment, by arranging any four adjacent collision balls 2 in a rectangular or rhombic manner, it can be ensured that the centers of the collision balls 2 in the lower oil-water separation ball grid layer 100 are directly opposite to the center of the convergence space 5 of the upper oil-water separation ball grid layer 100, forming multi-layered flow deflection and convergence.

[0040] Specifically, an anti-blocking channel 210 is provided between any two adjacent oil-water separation ball grid layers 100. As Figure 6 shown, the multi-layer oil-water separation ball grid layers 100 are arranged at uniform intervals, and any two adjacent oil-water separation ball grid layers 100 do not contact each other, which can avoid the situation of blockage of sediment and other impurities between two adjacent oil-water separation ball grid layers 100. It should be noted that the length of the anti-blocking channel 210 is L2, the outer diameter of the collision ball 2 is d, and L2 = b * d, where b is: 0.8 to 2.2. When the outer diameter of the collision ball 2 is 10 mm to 50 mm, the anti-blocking channel 210 with 0.8 to 2.2 times can prevent blockage of polydisperse particles with a particle size of 0.08 mm - 110 mm.

[0041] In one embodiment, the ball grid type oil-water separation and coalescence component 200 is composed of a multi-layer grid structure formed by a plurality of collision balls 2 and connecting pipes 1 connected in series therewith. The collision ball 2 is a spherical structure with a hollow interior and an outer diameter of 20 mm; a through hole is formed through the middle of each collision ball 2, and the inner diameter of the through hole is adapted to the outer diameter of the connecting pipe 1 for connecting with the connecting pipe 1; the collision ball 2 is made of stainless steel. In the ball grid type oil-water separation and coalescence component 200, in each oil-water separation ball grid layer 100, four adjacent collision balls 2 are arranged in a rectangular manner, and the collision balls 2 are located at the four vertices of the rectangle, and the distance between the collision balls 2 is 25 mm; the multi-layer oil-water separation ball grid layers 100 are parallel to each other, and the collision balls 2 in adjacent two oil-water separation ball grid layers 100 are arranged in a staggered manner. The center of the ball of the collision ball 2 in the lower layer of the ball grid is aligned with the center of the rectangular arrangement of the upper layer of the ball grid, and the distance between adjacent two oil-water separation ball grid layers 100 is 30 mm. The plurality of connecting pipes 1 that are parallel to each other and arranged in a staggered manner are made of stainless steel, and the outer diameter of the connecting pipe 1 is 8 mm; the plurality of connecting pipes 1 installed on the fixing plate 300 can form a regular three-dimensional support frame for the collision balls 2, and the connecting pipe 1 and the fixing plate 300 can be connected by bolts or other connecting pieces. The connection mode between the connecting pipe 1 and the collision ball 2 is as follows: a plurality of collision balls 2 are uniformly connected in series on the connecting pipe 1, the connecting pipe 1 passes through the through hole of the collision ball 2, and the collision ball 2 and the connecting pipe 1 are fixedly connected by welding. During the separation process of the oily sewage, when the mixed fluid containing oil, mud and water passes through the ball grid type oil-water separation and coalescence component 200, the pressure difference drives the discrete small oil droplets to migrate towards the surface of the collision ball 2, and the collision probability of the oil droplets and the spherical surface is increased by orderly changing the flow deflection direction of the fluid. The high specific surface area of the collision ball 2 is used to increase the coalescence residence time of the oil droplets, so that the oil droplets can achieve efficient coalescence. As the coalescence process continues, the oil droplet particles gradually increase. When they reach a certain size, they float to the upper surface of the water body under the action of buoyancy to achieve oil-water separation. The solid impurities such as sediment particles flowing through the ball grid type oil-water separation and coalescence component 200 sink under the action of gravity through the first anti-blocking gap 3 in the second direction, the second anti-blocking gap 4 in the first direction and the anti-blocking channel 210 along the water flow direction between the plurality of collision balls 2, forming anti-blocking in three-dimensional space and avoiding the blockage of the ball grid type oil-water separation and coalescence component 200 by impurities.

[0042] In another embodiment, four adjacent collision balls 2 in the single-layer oil-water separation ball grid layer 100 are arranged in a rhombus manner, the length of the second anti-blocking gap 4 is 36 mm, the outer diameter of the collision ball 2 is 30 mm, and the collision ball 2 is made of an oil-loving material; the length of the anti-blocking channel 210 between adjacent two oil-water separation ball grid layers 100 is 54 mm. The material of the connecting pipe 1 is a high-strength engineering plastic, and the outer diameter of the connecting pipe 1 is 12 mm. The collision ball 2 and the connecting pipe 1 are fixedly connected by bonding.

[0043] The present invention also provides an oil-water separator, which includes a fixing plate 300 and the above-mentioned spherical grid type oil-water separation and aggregation structural member 200, and both ends of the connecting pipe 1 along the pipe axis are connected to the fixing plate 300. As Figure 2 shown, the fixing plate 300 in this embodiment is an annular plate with an installation cavity, and the multi-layer oil-water separation spherical grid layers 100 of the spherical grid type oil-water separation and aggregation structural member 200 can be sequentially and spacedly installed along the axis of the fixing plate 300.
