Description

Technical Field

[0001] This utility model relates to industrial condensate treatment technology, specifically to an industrial condensate oil-water separation structure and an oil removal filter. Background Technology

[0002] During the petroleum refining process, due to pipeline leaks and other reasons, steam condensate may contain a small amount of oil. Removing the oil from the condensate is of great significance for improving the utilization rate of condensate, effectively utilizing heat energy, saving energy, and reducing environmental pollution.

[0003] In existing technologies, various methods are commonly used for oil removal from condensate, including gravity oil removal, coke or activated carbon filtration, fiber adsorption oil removal, fiber ball + activated carbon oil removal, membrane laying and bursting method oil removal, and extraction-like oil removal. However, in current fiber adsorption oil removal methods, the oil droplets adsorbed in the fiber pores need to rely on gravity generated by the aggregation of oil droplets to detach from the fiber block. The entire oil droplet aggregation process is slow, which affects the oil removal efficiency of the condensate. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an industrial condensate oil-water separation structure and an oil removal filter, which solves the problem that in current fiber adsorption oil removal processes, the oil droplets adsorbed in the fiber pores need to rely on the gravity generated by the accumulation of oil droplets to detach from the fiber block, resulting in a slow oil droplet accumulation process.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] In this utility model, an industrial condensate oil-water separation structure includes a tank, a water inlet structure, a discharge structure, a perforated plate one and a perforated plate two. The inner cavity of the tank is divided into an upper cavity, a middle cavity and a lower cavity by the perforated plate one and the perforated plate two.

[0009] The cavity between porous plate one and porous plate two is filled with fiber blocks.

[0010] Both the perforated plate one and the perforated plate two are located inside the tank, with the perforated plate one located below the perforated plate two.

[0011] A geared motor is installed on the top of the tank. A threaded rod is fixedly connected to the output end of the geared motor. The end of the threaded rod away from the geared motor extends into the interior of the tank and is rotatably connected to the perforated plate under the drive of the geared motor.

[0012] A slider is installed at the center of the perforated plate 2, and the perforated plate 2 is threaded onto the threaded rod by the slider.

[0013] The tank is equipped with multiple limiting posts inside. Each of the limiting posts is fixedly connected to the tank via a support plate. Each limiting post passes through a perforated plate II and is fixedly connected to a perforated plate I. The perforated plate II slides up and down along the axis of the limiting post via a sleeve block to compress the fiber block or restore it to its original state.

[0014] Furthermore, a limiting block is installed on the inner wall of the tank, and the limiting block is located above the perforated plate.

[0015] Furthermore, the fiber block is made of an oleophilic modified fiber material.

[0016] Furthermore, the feeding structure includes a connecting pipe connected to the tank body, the end of the connecting pipe connected to the tank body being higher than the limiting block, and the end of the connecting pipe away from the tank body serving as the raw water inlet.

[0017] The discharge structure includes a connecting pipe II that communicates with the tank body. The connection end of the connecting pipe II to the tank body is located at the bottom of the tank body, and the end of the connecting pipe II away from the tank body serves as a drain outlet for filtered water.

[0018] An oil removal filter utilizes an oil-water separation structure to separate oil and water in condensate, and also includes an oil collection structure and a backwashing structure;

[0020] After oil-water separation, the oil is introduced into the oil collection area through multiple oil guide pipes, and the oil collected in the oil collection area is discharged from the tank through the oil outlet pipe for collection.

[0021] The backwashing structure includes a backwash outlet on the first connecting pipe, a backwash inlet and a compressed air inlet on the second connecting pipe, and an air outlet on the top of the tank.

[0022] Furthermore, the second connecting pipe is also equipped with a forward wash outlet, and the raw water inlet is used as the forward wash water inlet.

[0023] (III) Beneficial Effects

[0024] This utility model provides an industrial condensate oil-water separation structure and an oil removal filter. Compared with the prior art, it has the following advantages:

[0025] By adding a geared motor, a threaded rod, and a perforated plate with threads mounted on the threaded rod to the existing condensate oil removal filter, the geared motor drives the threaded rod to rotate, causing the perforated plate to squeeze the fiber block, expelling the oil adsorbed by the fiber block. This facilitates subsequent oil-water separation and oil drainage, solving the problem that in current fiber adsorption oil removal processes, oil droplets adsorbed in the fiber pores need to rely on gravity to detach from the fiber block, resulting in a slow oil droplet aggregation process. This achieves highly efficient oil removal from condensate using the filter. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] This application provides an industrial condensate oil-water separation structure and an oil removal filter, which solves the problem that in current fiber adsorption oil removal, the oil droplets adsorbed in the fiber pores need to rely on the gravity generated by the accumulation of oil droplets to detach from the fiber block, and the entire oil droplet accumulation process is slow, thus achieving efficient oil removal of condensate by the filter.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example:

[0035] like Figures 1-2 As shown, an industrial condensate oil-water separation structure includes a tank 1, a water inlet structure, a discharge structure, a perforated plate 10 and a perforated plate 11. The inner cavity of the tank 1 is divided into an upper cavity 101, a middle cavity 102 and a lower cavity 103 by the perforated plate 10 and the perforated plate 11.

[0036] The cavity 102 located between the porous plate 10 and the porous plate 11 is filled with fiber block 1021.

[0037] Both the first perforated plate 10 and the second perforated plate 11 are located inside the tank body 1, with the first perforated plate 10 located below the second perforated plate 11.

[0038] A geared motor 2 is installed on the top of the tank body 1. A threaded rod 20 is fixedly connected to the output end of the geared motor 2. The end of the threaded rod 20 away from the geared motor 2 extends into the interior of the tank body 1 and is rotatably connected to the perforated plate 10 under the drive of the geared motor 2.

[0039] A slider 21 is installed at the center of the perforated plate 11, and the perforated plate 11 is threadedly sleeved on the threaded rod 20 through the slider 21.

[0040] The tank body 1 is equipped with multiple limiting posts 12. The multiple limiting posts 12 are fixedly connected to the tank body 1 through a support plate 131. Each limiting post 12 passes through a perforated plate 2 11 and is fixedly connected to a perforated plate 10. The perforated plate 2 11 slides up and down along the axis of the limiting post 12 through a sleeve block 111, so that the fiber block 1021 is in a compressed state or returns to its original state.

[0041] Specifically, during use, fiber block 1021 can be adsorbed using oleophilic modified fiber materials.

[0042] By adding a geared motor 2, a threaded rod 20, and a perforated plate 11 threaded onto the threaded rod 20 to the existing condensate oil removal filter, the geared motor 2 drives the threaded rod 20 to rotate, causing the perforated plate 11 threaded onto the threaded rod 20 to squeeze the fiber block 1021, squeezing out the oil adsorbed by the fiber block 1021. This facilitates subsequent oil-water separation and oil drainage operations, solving the problem that in current fiber adsorption oil removal processes, the oil droplets adsorbed in the fiber pores need to rely on gravity generated by the accumulation of oil droplets to detach from the fiber block 1021, resulting in a slow oil droplet accumulation process. This achieves highly efficient oil removal from condensate by the filter.

[0043] It should be noted that during the entire process, the structure involved in the up-and-down sliding of the porous plate 11 to compress the fiber block 1021 will not interfere with the internal structure of the original filter.

[0044] like Figure 1 As shown, a limiting block 14 is installed on the inner wall of the tank 1. The limiting block 14 is located above the perforated plate 11 and is used to limit the highest limit of the perforated plate 11. The distance between the fiber block 1021 and the perforated plate 11 after the perforated plate 11 reaches the highest limit is observed, and the state of the fiber block 1021 returning to its original state is determined by this. If the fiber block 1021 does not contact the perforated plate 11 at the highest limit position after returning to its original state, it indicates that the function of the fiber block 1021 has decreased.

[0045] In practical applications, when the fiber block 1021 returns to its original state and reaches a certain distance from the perforated plate 11 at the highest limit position, the replacement cycle of the fiber block 1021 is used to jointly determine whether the fiber block 1021 needs to be replaced. The restoration of the fiber block 1021 to its original state is used as one of the criteria for replacing the fiber block 1021.

[0046] Specifically, the tank 1 is equipped with multiple sight glasses for observing the usage status of the fiber block 1021, and is also equipped with a manhole and discharge port, which are conventional features of existing large filters.

[0047] The technical principle of the oil-water separation structure utilizes the strong oleophilic and hydrophobic properties of cellulose short fibers modified with strong hydrophobic groups (adsorption value of 20 g / L fiber) to adsorb oil present in condensate. After adsorption saturation, most of the adsorbed oil is removed by mechanical means (extrusion). Furthermore, the adsorption state of fiber block 1021 can be restored to its initial state to achieve the purpose of reuse.

[0048] Specifically, the feeding structure includes a connecting pipe 3 connected to the tank body 1. The connection end of the connecting pipe 3 to the tank body 1 is higher than the limiting block 14, and the end of the connecting pipe 3 away from the tank body 1 serves as the raw water inlet 30.

[0049] The discharge structure includes a connecting pipe 4 that is connected to the tank 1. The connection end of the connecting pipe 4 to the tank 1 is located at the bottom of the tank 1, and the end of the connecting pipe 4 away from the tank 1 serves as a filtered water drain outlet 43.

[0050] like Figures 1-2 As shown, an industrial condensate oil removal filter uses an oil-water separation structure to separate oil and water in condensate, and also includes an oil collection structure and a backwashing structure.

[0051] The oil collection structure includes an oil collection area 104 and multiple oil guide pipes 13. The oil collection area 104 is located at the top of the inner cavity of the tank body 1. The bottom ends of the multiple oil guide pipes 13 pass through the perforated plate 11 and are fixed to the perforated plate 10. The top ends of the multiple oil guide pipes 13 extend to the oil collection area 104 and are fixed to the support plate 131.

[0052] After oil-water separation, the oil is introduced into the oil collection area 104 through multiple oil guide pipes 13, and the oil collected in the oil collection area 104 is discharged from the tank 1 through the oil outlet pipe 5 for collection.

[0053] The backwashing structure includes a backwashing outlet 31 on the connecting pipe 1 3, a backwashing inlet 40 and a compressed air inlet 41 on the connecting pipe 2 4, and an air outlet pipe 6 on the top of the tank body 1.

[0054] Among them, the backwash outlet 31 and backwash inlet 40 are used for backwash water washing operation, and the compressed air inlet 41 and air outlet 6 are used for backwash air washing operation, which facilitates the cleaning of tank 1. In actual application, water washing or air washing can be selected for backwashing operation according to the actual filter material. Backwash air washing and backwash water washing are both existing technologies, and the specific working principle will not be elaborated here.

[0055] Specifically, the connecting pipe 4 is also provided with a forward wash outlet 42, and the raw water inlet 30 is used as the inlet for the forward wash water.

[0056] It should be noted that pressure gauges and sampling valves are installed on the raw water inlet 30 and the backwash outlet 31 respectively to monitor the raw water inlet flow and the backwash outlet flow and pressure in real time, so as to facilitate the filtration and backwashing operations of the filter. In the application process, pressure gauges and sampling valves are set on the backwash inlet 40, compressed air inlet 41, forward wash outlet 42 and filter water outlet 43 according to the needs of the existing technology.

[0057] Furthermore, each flow inlet and outlet of the filter is equipped with a corresponding valve to control the flow rate.

[0058] During operation, the condensate from industrial production undergoes preliminary filtration. The condensate requiring further filtration enters the tank 1 through the connecting pipe 3 via the raw water inlet 30. The oil-containing condensate flows to the top of the fiber block 1021. At this point, the fiber block 1021 utilizes the strong oleophilic and hydrophobic properties of the cellulose short fibers modified with strong hydrophobic groups to adsorb the oil present in the condensate. The oil-free condensate falls through the fiber block 1021 into the lower part 103 of the cavity. Subsequently, the oil adsorbed inside the fiber block 1021 falls into the lower part 103 of the cavity under the action of gravity and the compression of the porous plate 11, forming a layer with the water in the lower part 103, with oil on top and water on the bottom. The water in the lower layer is discharged and collected through the filtered water drain outlet 43, while the oil in the upper layer is introduced into the oil collection area 104 through the oil guide pipe 13 and discharged and collected through the oil outlet pipe 5.

[0059] When the perforated plate 11 squeezes the fiber block 1021, the geared motor 2 rotates forward or reverse to drive the threaded rod 20 to rotate, thereby controlling the perforated plate 11, which is threaded on the threaded rod 20, to slide upward or downward along the vertical direction, so as to realize the squeezing of the fiber block 1021 by the perforated plate 11.

[0060] Next, tank 1 was cleaned using a combination of forward and reverse washing, depending on the actual situation.

[0061] During the forward wash, the cleaning water enters the tank 1 through the raw water inlet 30 and cleans the inner cavity of the tank 1. The cleaned water flows out through the forward wash outlet 42 and is collected.

[0062] Backwashing includes water backwashing and air backwashing:

[0063] During backwashing, the cleaning water flows upward from the bottom of the tank 1 through the backwash inlet 40, and the cleaned water flows out through the backwash outlet 31.

[0064] During backwashing, gas enters the tank 1 through the compressed air inlet 41 to clean the inner cavity of the tank 1. Afterward, the gas used for cleaning is discharged through the air outlet 6, completing the gas washing operation of the filter.

[0065] In summary, compared with existing technologies, it has the following beneficial effects:

[0066] 1. By adding a geared motor 2, a threaded rod 20, and a perforated plate 11 threaded onto the threaded rod 20 to the existing condensate oil removal filter, the geared motor 2 drives the threaded rod 20 to rotate, causing the perforated plate 11 threaded onto the threaded rod 20 to squeeze the fiber block 1021, squeezing out the oil adsorbed by the fiber block 1021. This facilitates subsequent oil-water separation and oil discharge operations, solving the problem that in current fiber adsorption oil removal, the oil droplets adsorbed in the fiber pores need to rely on the gravity generated by the oil droplet aggregation to detach from the fiber block 1021, resulting in a slow oil droplet aggregation process. This achieves highly efficient oil removal from condensate by the filter.

[0067] 2. By setting a limiting block 14, the maximum limit of the porous plate 11 is restricted. The distance between the fiber block 1021 and the porous plate 11 after the porous plate 11 reaches the maximum limit is observed. The state of the fiber block 1021 returning to its original state is determined by this. If the fiber block 1021 does not contact the porous plate 11 at the maximum limit position after returning to its original state, it indicates that the function of the fiber block 1021 has decreased.
