Description

Technical Field

[0001] The invention relates to the technical field of catalytic cracking oil slurry purification, and in particular to an electrostatic separator for improving filler utilization and an installation method thereof. Background Art

[0002] With the continuous improvement of my country's catalytic cracking processing capacity, the output of catalytic slurry oil is also increasing year by year. The output of slurry oil generally accounts for about 5% to 10% of the catalytic cracking processing volume. Since the main components of catalytic slurry oil are polycyclic aromatic hydrocarbons and catalyst particles, it is easy to produce coke and release a large amount of heat during the recycling process, which greatly reduces the safety and stability of the device; it also seriously affects the quality of catalytic cracking products. Therefore, it is necessary to partially discard the catalytic slurry oil, which creates the need for efficient utilization of a large amount of discarded slurry oil.

[0003] The part of catalytic oil slurry that can be efficiently utilized is polycyclic aromatic hydrocarbons, while catalyst particles will seriously affect the quality of needle coke, carbon fiber, carbon black, emulsified asphalt and other high value-added products. Therefore, the premise for the high-value utilization of catalytic oil slurry is to effectively remove the catalytic particles therein. At present, the main methods for purifying catalytic cracking oil slurry include water washing method, gravity sedimentation method, centrifugal separation method, filtration separation method and electrostatic separation method. Among them, electrostatic separation has the advantages of high separation efficiency, large processing capacity, small pressure drop, and is suitable for removing micron-sized and submicron-sized catalyst particles with a particle size of less than 10μm. When electrostatically separating catalysts from catalytic oil slurry, fillers such as glass beads need to be added to enhance the local electric field strength. The angle between the line connecting the centers of the filler circles and the electric field lines will affect the enhancement of the local electric field strength. Taking common glass beads as an example, when the line connecting two glass bead fillers is parallel to the electric field lines, the increase in local field strength reaches the maximum value. When the line between the fillers is perpendicular to the electric field lines, not only will the field strength not increase, it may even weaken the field strength. Therefore, in the process of separating solids from catalytic cracking oil slurry, the effective utilization rate of the filler is crucial. So far, the common way to add fillers is the disordered stacking method, which results in a large amount of filler utilization being low or even unutilized during the electrostatic separation process, increasing the economic cost and affecting the electrostatic separation efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the above-mentioned existing background technology, so as to improve the utilization rate of fillers in the electrostatic separation process, reduce the amount of fillers used in the electrostatic separation process, and solve the technical problems of low or even non-utilization of fillers in the prior art. Therefore, an electrostatic separator with improved filler utilization and an installation method thereof are provided.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An electrostatic separator for improving filler utilization rate comprises a cylinder, an electrode column coaxially arranged inside the cylinder, and a plurality of filler plates stacked horizontally inside the cylinder. The top of the cylinder is provided with an end cap threadedly connected to the cylinder, the bottom of the inner side wall of the cylinder is provided with a filler plate clamping groove for supporting the filler plate, the inner side of the bottom of the cylinder is provided with an electrode column rotating groove for connecting and fixing the electrode column, an oil slurry outlet is provided on one side of the radius of the bottom of the cylinder, and an oil slurry inlet is provided on the upper part of the side wall of the cylinder.

[0007] The packing plates are divided into even-numbered packing plates and odd-numbered packing plates, which are alternately stacked inside the cylinder and placed on the packing plate slots; the even-numbered packing plates and odd-numbered packing plates are both provided with an electrode hole at the center and a plurality of groups of packing plate baffles, which are arranged in equidistant circles with the center of the electrode hole as the center point, and each group of packing plate baffles includes two parallel baffles, which form a strip-shaped packing area on the packing plate, and two adjacent groups of packing plate baffles form a conical packing area on the packing plate, and packing placement holes are provided in the strip-shaped packing area and the conical packing area, and the packing placement holes are all arranged on the radial axis of the packing plate; each packing placement hole is used to fix the position of each packing.

[0008] The bottom end of the electrode column is installed in an electrode column rotation groove arranged inside the cylinder.

[0009] Furthermore, the diameters of the even-numbered packing plates and the odd-numbered packing plates are equal and both smaller than the inner diameter of the cylinder; the number and distribution positions of the packing plate baffles arranged thereon are the same, and the number of the packing plate baffles depends on the size of the packing and the size of the packing plate. The number of the packing plate baffles is directly proportional to the size of the packing plate and inversely proportional to the size of the packing.

[0010] Furthermore, the distance between two baffles in each group of packing plate baffles is smaller than the packing diameter, and the height of the baffle is smaller than the packing radius.

[0011] Furthermore, an even number of filler placement holes are provided in the strip filler area on the even-numbered filler plate, and an odd number of filler placement holes are provided in the strip filler area on the odd-numbered filler plate, and the number of filler placement holes in the strip filler area on the odd-numbered filler plate is one more than that on the even-numbered filler plate.

[0012] Furthermore, the number of the packing placement holes in the conical packing area on the even-numbered packing plate is consistent with the number of the packing placement holes in the conical packing area on the odd-numbered packing plate.

[0013] Furthermore, the arrangement positions of the filler placement holes in the strip filler area and the conical filler area on the even-numbered filler plates and the odd-numbered filler plates are different, and the two are staggered and distributed, and the staggered distance is the radius of the filler.

[0014] Furthermore, the fillers placed on the even-numbered filler plates and the fillers on the odd-numbered filler plates can contact each other vertically, and there is an angle between a line connecting the centers of two adjacent fillers and a vertical line, and the degree of the angle ranges from 30° to 60°.

[0015] Furthermore, the electrode hole is located at the center of the filler plate and is matched with the electrode column. A circle of baffles is arranged around the electrode hole. The electrode column is made of copper material.

[0016] The present invention also provides an installation method of an electrostatic separator for improving filler utilization, which is applied to the above-mentioned electrostatic separator and comprises the following steps:

[0017] 1) Open the end cover of the electrostatic separator and remove all the packing plates therein;

[0018] 2) Place the even-numbered packing plates and the odd-numbered packing plates separately, place the packing in the strip-shaped packing area and the conical packing area according to the position of the packing placement holes, and then place the packing in the annular packing area closely;

[0019] 3) Place the packing plates after packing into the cylinder in the order of odd and even numbers;

[0020] 4) Tighten the end cap.

[0021] Furthermore, during the process of placing into the cylinder in step 3), the strip packing areas on the even-numbered packing plates are vertically opposite to the strip packing areas on the odd-numbered packing plates, and the conical packing areas on the even-numbered packing plates are vertically opposite to the conical packing areas on the odd-numbered packing plates.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the present invention adopts a method of controlling the placement of fillers through a filler plate, and improves the utilization rate of fillers in the electrostatic separation process by adjusting the placement angle of the fillers, so that the separation efficiency of the same amount of fillers is improved, or the amount of fillers in the electrostatic separation process is reduced, thereby reducing the experimental cost and solving the technical problem of low or even non-utilization of fillers.

[0030] The specific embodiments of the present invention are further described in detail and completely below in conjunction with the accompanying drawings:

[0031] Embodiment 1,

[0032] like Figure 1As shown, an electrostatic separator for improving filler utilization rate comprises a cylinder 1, an electrode column 2 coaxially arranged inside the cylinder 1, and a plurality of filler plates stacked horizontally inside the cylinder 1. The top of the cylinder 1 is open and the inside is hollow, and an end cap 3 threadedly connected to the cylinder 1 is provided at the top opening of the cylinder 1; an electrode column rotation groove 6 is provided at the center of the inner bottom of the cylinder 1, and the bottom end of the electrode column 2 is fixedly connected in the electrode column rotation groove 6 so that it is vertically installed in the center of the cylinder 1. The electrode column 2 is made of copper material with good electrical conductivity and serves as the anode of the entire electrostatic separator. The cylinder 1 is also made of material with good electrical conductivity and serves as the cathode of the entire electrostatic separator; at the same time, insulating material is laid in the electrode column rotation groove 6 to insulate and separate the cylindrical electrode column 2 from the cylinder 1. A packing plate slot 7 for supporting a packing plate is provided at the bottom of the inner side wall of the cylinder 1, and the packing plate is horizontally stacked on the packing plate slot 7; at the same time, one side of the radius of the bottom of the cylinder 1 protrudes downward to form a conical funnel shape (the upper end diameter of the conical funnel-shaped structure is equal to the radius of the bottom of the cylinder 1, and gradually shrinks downward), and an oil slurry outlet 5 is provided at the bottom end of the conical funnel-shaped structure, and an oil slurry inlet 4 corresponding to the oil slurry outlet 5 is provided on the upper part of the side wall of the cylinder 1, and corresponding valves are provided at the oil slurry inlet 4 and the oil slurry outlet 5 for injecting and discharging the oil slurry.

[0033] The packing plates are divided into even-numbered packing plates 8 and odd-numbered packing plates 9 according to the order of odd and even numbers of the packing plates stacked in the cylinder 1. The two packing plates are alternately stacked and horizontally placed in the cylinder 1 above the packing plate slots 7. Figure 2 and Figure 3As shown, the even-numbered packing plates 8 and the odd-numbered packing plates 9 are both provided with a circular electrode hole 15 for the electrode column 2 to pass through at the center, and a circle of annular baffles 17 are fixedly provided on the periphery of the electrode hole 15; a plurality of groups of packing plate baffles are also provided on the even-numbered packing plates 8 and the odd-numbered packing plates 9, and the plurality of groups of packing plate baffles are arranged in an equidistant circle with the center of the electrode hole 15 as the center point, and each group of packing plate baffles includes two parallel baffles 11, and the two baffles 11 surround a strip-shaped packing area 12 on the corresponding packing plate; two adjacent groups of packing plate baffles A conical filling area 13 is formed on the corresponding filling plate. As the inner ends of the strip filling areas 12 converge, an inner angle of the conical filling area 13 is formed. A circular filling area 14 is formed between the inner angles of the multiple conical filling areas 13 and the electrode holes 15. Multiple filling placement holes 16 are provided in each strip filling area 12 and each conical filling area 13. The filling placement holes 16 in the strip filling area 12 are arranged along the radial axis of the filling plate in its length direction, and the filling placement holes 16 in the conical filling area 13 are arranged along the radial axis of the filling plate on the center line of its inner angle. Each filling placement hole 16 is used to fix the position of a filler 10. The diameter of the filling placement hole 16 is slightly smaller than the spherical diameter of the filler 10, so as to facilitate the stable placement of the filler 10. The spacing between two adjacent filling placement holes 16 on each radial axis is adjusted according to the size of the filler 10, so that the filler 10 can be closely arranged after placement.

[0034] The diameters of the even-numbered packing plates 8 and the odd-numbered packing plates 9 are equal and smaller than the inner diameter of the cylinder 1, so as to facilitate placement, installation and recovery, and facilitate the circulation and desolidification of the oil slurry. The number and distribution positions of the packing plate baffles arranged thereon are the same. The number of the packing plate baffles depends on the size of the packing 10 and the overall size of the packing plate. The number of the packing plate baffles is proportional to the size of the packing plate and inversely proportional to the size of the packing 10, and follows the following two principles: (1) the proportion of the enclosed strip packing area 12 is as large as possible, and (2) the proportion of the circular packing area 14 enclosed by the conical packing area 13 and the electrode hole 15 is as small as possible. The two principles are inversely proportional. Therefore, the number of the strip packing areas 12 to be set should be selected appropriately according to the size of the packing plate and the radius of the packing 10. The spacing width of the two baffles 11 in each group of packing plate baffles is slightly smaller than the diameter of the packing 10, and the height of the baffle 11 is slightly smaller than the radius of the packing 10, so as to fix the position of the packing 10 and prevent the packing 10 from being displaced or rolled off.

[0035] Further optimized, an even number of filler placement holes 16 are provided in the strip filler area 12 on the even filler plate 8, and an odd number of filler placement holes 16 are provided in the strip filler area 12 on the odd filler plate 9, and the number of filler placement holes 16 in the strip filler area 12 on the odd filler plate 9 is one more than that on the even filler plate 8. The number of filler placement holes 16 in the conical filler area 13 on the even filler plate 8 is consistent with the number of filler placement holes 16 in the conical filler area 13 on the odd filler plate 9. The filler placement holes 16 in the strip filler area 12 and the conical filler area 13 on the even filler plate 8 and the odd filler plate 9 are of the same size but in different positions, and the two are staggered, with an interlaced distance of the radius of a filler 10, in order to make the center line between the upper and lower fillers 10 form an angle with the electric field line, so that the adsorption effect is best when it is parallel to the electric field line, and the adsorption effect is worst when it is perpendicular.

[0036] Furthermore, if Figure 4 As shown, the fillers 10 placed on the even-numbered filler plate 8 and the fillers 10 placed on the odd-numbered filler plate 9 can contact each other up and down, and there is an angle θ between the center line of two adjacent fillers 10 and the vertical line. The degree of the angle θ is 30°, and the filler has the best adsorption effect and the highest utilization rate.

[0037] The filler plate is made of a material with high strength and good insulation performance.

[0038] The present invention also provides an installation method of an electrostatic separator for improving filler utilization, which specifically comprises the following steps:

[0039] 1) Open the end cover 3 of the electrostatic separator and remove all the packing plates therein;

[0040] 2) The even-numbered filler plates 8 and the odd-numbered filler plates 9 are placed separately, and the corresponding fillers 10 are placed in the strip-shaped filler areas 12 and the conical filler areas 13 according to the positions of the filler placement holes 16 set therein, and the fillers 10 are tightly laid in the unpunched idle areas of the annular filler areas 14 and the conical filler areas 13, so as to improve the utilization rate of the filler plates, and to fix the fillers 10 in the strip-shaped filler areas 12 while playing a role in desoldering, so that the fillers 10 are not easily offset; the annular baffle 17 just prevents the fillers 10 from moving and falling from the electrode holes 15;

[0041] 3) The packing plates after the packing 10 is placed are alternately placed into the cylinder 1 in the order of odd and even; the strip packing area 12 on the even packing plate 8 is aligned with the strip packing area 12 on the odd packing plate 9, and the conical packing area 13 on the even packing plate 8 is aligned with the conical packing area 13 on the odd packing plate 9; at this time, there is a misalignment of a packing radius between the packing 10 placed on the even packing plate 8 and the packing 10 placed on the odd packing plate 9, so that the two are in contact with each other up and down, preventing the vertical unutilized situation between the upper and lower packings;

[0042] 4) Then tighten the end cap 3.

[0043] Embodiment 2,

[0044] like Figure 1 As shown, an electrostatic separator for improving filler utilization rate comprises a cylinder 1, an electrode column 2 coaxially arranged inside the cylinder 1, and a plurality of filler plates stacked horizontally inside the cylinder 1. The top of the cylinder 1 is open and the inside is hollow, and an end cap 3 threadedly connected to the cylinder 1 is provided at the top opening of the cylinder 1; an electrode column rotation groove 6 is provided at the center of the inner bottom of the cylinder 1, and the bottom end of the electrode column 2 is fixedly connected in the electrode column rotation groove 6 so that it is vertically installed in the center of the cylinder 1. The electrode column 2 is made of copper material with good electrical conductivity and serves as the anode of the entire electrostatic separator. The cylinder 1 is also made of material with good electrical conductivity and serves as the cathode of the entire electrostatic separator; at the same time, insulating material is laid in the electrode column rotation groove 6 to insulate and separate the cylindrical electrode column 2 from the cylinder 1. A packing plate slot 7 for supporting a packing plate is provided at the bottom of the inner side wall of the cylinder 1, and the packing plate is horizontally stacked on the packing plate slot 7; at the same time, one side of the radius of the bottom of the cylinder 1 protrudes downward to form a conical funnel shape (the upper end diameter of the conical funnel-shaped structure is equal to the radius of the bottom of the cylinder 1, and gradually shrinks downward), and an oil slurry outlet 5 is provided at the bottom end of the conical funnel-shaped structure, and an oil slurry inlet 4 corresponding to the oil slurry outlet 5 is provided on the upper part of the side wall of the cylinder 1, and corresponding valves are provided at the oil slurry inlet 4 and the oil slurry outlet 5 for injecting and discharging the oil slurry.

[0045] The packing plates are divided into even-numbered packing plates 8 and odd-numbered packing plates 9 according to the order of odd and even numbers of the packing plates stacked in the cylinder 1. The two packing plates are alternately stacked and horizontally placed in the cylinder 1 above the packing plate slots 7. Figure 2 and Figure 3As shown, the even-numbered packing plates 8 and the odd-numbered packing plates 9 are both provided with a circular electrode hole 15 for the electrode column 2 to pass through at the center, and a circle of annular baffles 17 are fixedly provided on the periphery of the electrode hole 15; a plurality of groups of packing plate baffles are also provided on the even-numbered packing plates 8 and the odd-numbered packing plates 9, and the plurality of groups of packing plate baffles are arranged in an equidistant circle with the center of the electrode hole 15 as the center point, and each group of packing plate baffles includes two parallel baffles 11, and the two baffles 11 surround a strip-shaped packing area 12 on the corresponding packing plate; two adjacent groups of packing plate baffles A conical filling area 13 is formed on the corresponding filling plate. As the inner ends of the strip filling areas 12 converge, an inner angle of the conical filling area 13 is formed. A circular filling area 14 is formed between the inner angles of the multiple conical filling areas 13 and the electrode holes 15. Multiple filling placement holes 16 are provided in each strip filling area 12 and each conical filling area 13. The filling placement holes 16 in the strip filling area 12 are arranged along the radial axis of the filling plate in its length direction, and the filling placement holes 16 in the conical filling area 13 are arranged along the radial axis of the filling plate on the center line of its inner angle. Each filling placement hole 16 is used to fix the position of a filler 10. The diameter of the filling placement hole 16 is slightly smaller than the spherical diameter of the filler 10, so as to facilitate the stable placement of the filler 10. The spacing between two adjacent filling placement holes 16 on each radial axis is adjusted according to the size of the filler 10, so that the filler 10 can be closely arranged after placement.

[0046] The diameters of the even-numbered packing plates 8 and the odd-numbered packing plates 9 are equal and smaller than the inner diameter of the cylinder 1, so as to facilitate placement, installation and recovery, and facilitate the circulation and desolidification of the oil slurry. The number and distribution positions of the packing plate baffles arranged thereon are the same. The number of the packing plate baffles depends on the size of the packing 10 and the overall size of the packing plate. The number of the packing plate baffles is proportional to the size of the packing plate and inversely proportional to the size of the packing 10, and follows the following two principles: (1) the proportion of the enclosed strip packing area 12 is as large as possible, and (2) the proportion of the circular packing area 14 enclosed by the conical packing area 13 and the electrode hole 15 is as small as possible. The two principles are inversely proportional. Therefore, the number of the strip packing areas 12 to be set should be selected appropriately according to the size of the packing plate and the radius of the packing 10. The spacing width of the two baffles 11 in each group of packing plate baffles is slightly smaller than the diameter of the packing 10, and the height of the baffle 11 is slightly smaller than the radius of the packing 10, so as to fix the position of the packing 10 and prevent the packing 10 from being displaced or rolled off.

[0047] Further optimized, an even number of filler placement holes 16 are provided in the strip filler area 12 on the even filler plate 8, and an odd number of filler placement holes 16 are provided in the strip filler area 12 on the odd filler plate 9, and the number of filler placement holes 16 in the strip filler area 12 on the odd filler plate 9 is one more than that on the even filler plate 8. The number of filler placement holes 16 in the conical filler area 13 on the even filler plate 8 is consistent with the number of filler placement holes 16 in the conical filler area 13 on the odd filler plate 9. The filler placement holes 16 in the strip filler area 12 and the conical filler area 13 on the even filler plate 8 and the odd filler plate 9 are of the same size but in different positions, and the two are staggered, and the staggered distance is the radius of a filler 10, in order to make the center line between the upper and lower fillers 10 form an angle with the electric field line.

[0048] Furthermore, if Figure 4 As shown, the fillers 10 placed on the even-numbered filler plates 8 and the fillers 10 placed on the odd-numbered filler plates 9 can contact each other vertically, and an angle θ exists between a line connecting the centers of two adjacent fillers 10 and a vertical line, and the angle θ is 45°.

[0049] The filler plate is made of a material with high strength and good insulation performance.

[0050] The specific installation method of the electrostatic separator for improving filler utilization comprises the following steps:

[0051] 1) Open the end cover 3 of the electrostatic separator and remove all the packing plates therein;

[0052] 2) The even-numbered filler plates 8 and the odd-numbered filler plates 9 are placed separately, and the corresponding fillers 10 are placed in the strip-shaped filler areas 12 and the conical filler areas 13 according to the positions of the filler placement holes 16 set therein, and the fillers 10 are tightly laid in the unpunched idle areas of the annular filler areas 14 and the conical filler areas 13, so as to improve the utilization rate of the filler plates, and to fix the fillers 10 in the strip-shaped filler areas 12 while playing a role in desoldering, so that the fillers 10 are not easily offset; the annular baffle 17 just prevents the fillers 10 from moving and falling from the electrode holes 15;

[0053] 3) The packing plates after the packing 10 is placed are alternately placed into the cylinder 1 in the order of odd and even; the strip packing area 12 on the even packing plate 8 is aligned with the strip packing area 12 on the odd packing plate 9, and the conical packing area 13 on the even packing plate 8 is aligned with the conical packing area 13 on the odd packing plate 9; at this time, there is a misalignment of a packing radius between the packing 10 placed on the even packing plate 8 and the packing 10 placed on the odd packing plate 9, so that the two are in contact with each other up and down, preventing the vertical unutilized situation between the upper and lower packings;

[0054] 4) Then tighten the end cap 3.

As the inner ends of the strip filling areas 12 converge, an inner angle of the conical filling area 13 is formed. A circular filling area 14 is formed between the inner angles of the multiple conical filling areas 13 and the electrode holes 15. Multiple filling placement holes 16 are provided in each strip filling area 12 and each conical filling area 13. The filling placement holes 16 in the strip filling area 12 are arranged along the radial axis of the filling plate in its length direction, and the filling placement holes 16 in the conical filling area 13 are arranged along the radial axis of the filling plate on the center line of its inner angle. Each filling placement hole 16 is used to fix the position of a filler 10. The diameter of the filling placement hole 16 is slightly smaller than the spherical diameter of the filler 10, so as to facilitate the stable placement of the filler 10. The spacing between two adjacent filling placement holes 16 on each radial axis is adjusted according to the size of the filler 10, so that the filler 10 can be closely arranged after placement.

[0058] The diameters of the even-numbered packing plates 8 and the odd-numbered packing plates 9 are equal and smaller than the inner diameter of the cylinder 1, so as to facilitate placement, installation and recovery, and facilitate the circulation and desolidification of the oil slurry. The number and distribution positions of the packing plate baffles arranged thereon are the same. The number of the packing plate baffles depends on the size of the packing 10 and the overall size of the packing plate. The number of the packing plate baffles is proportional to the size of the packing plate and inversely proportional to the size of the packing 10, and follows the following two principles: (1) the proportion of the enclosed strip packing area 12 is as large as possible, and (2) the proportion of the circular packing area 14 enclosed by the conical packing area 13 and the electrode hole 15 is as small as possible. The two principles are inversely proportional. Therefore, the number of the strip packing areas 12 to be set should be selected appropriately according to the size of the packing plate and the radius of the packing 10. The spacing width of the two baffles 11 in each group of packing plate baffles is slightly smaller than the diameter of the packing 10, and the height of the baffle 11 is slightly smaller than the radius of the packing 10, so as to fix the position of the packing 10 and prevent the packing 10 from being displaced or rolled off.

[0059] Further optimized, an even number of filler placement holes 16 are provided in the strip filler area 12 on the even filler plate 8, and an odd number of filler placement holes 16 are provided in the strip filler area 12 on the odd filler plate 9, and the number of filler placement holes 16 in the strip filler area 12 on the odd filler plate 9 is one more than that on the even filler plate 8. The number of filler placement holes 16 in the conical filler area 13 on the even filler plate 8 is consistent with the number of filler placement holes 16 in the conical filler area 13 on the odd filler plate 9. The filler placement holes 16 in the strip filler area 12 and the conical filler area 13 on the even filler plate 8 and the odd filler plate 9 are of the same size but in different positions, and the two are staggered, and the staggered distance is the radius of a filler 10, in order to make the center line between the upper and lower fillers 10 form an angle with the electric field line.

[0060] Furthermore, if Figure 4 As shown, the fillers 10 placed on the even-numbered filler plate 8 and the fillers 10 placed on the odd-numbered filler plate 9 can contact each other vertically, and an angle θ exists between a line connecting the centers of two adjacent fillers 10 and a vertical line, and the angle θ is 60°.

[0061] The filler plate is made of a material with high strength and good insulation performance.

[0062] The specific installation method of the electrostatic separator for improving filler utilization comprises the following steps:

[0063] 1) Open the end cover 3 of the electrostatic separator and remove all the packing plates therein;

[0064] 2) The even-numbered filler plates 8 and the odd-numbered filler plates 9 are placed separately, and the corresponding fillers 10 are placed in the strip-shaped filler areas 12 and the conical filler areas 13 according to the positions of the filler placement holes 16 set therein, and the fillers 10 are tightly laid in the unpunched idle areas of the annular filler areas 14 and the conical filler areas 13, so as to improve the utilization rate of the filler plates, and to fix the fillers 10 in the strip-shaped filler areas 12 while playing a role in desoldering, so that the fillers 10 are not easily offset; the annular baffle 17 just prevents the fillers 10 from moving and falling from the electrode holes 15;

[0065] 3) The packing plates after the packing 10 is placed are alternately placed into the cylinder 1 in the order of odd and even; the strip packing area 12 on the even packing plate 8 is aligned with the strip packing area 12 on the odd packing plate 9, and the conical packing area 13 on the even packing plate 8 is aligned with the conical packing area 13 on the odd packing plate 9; at this time, there is a misalignment of a packing radius between the packing 10 placed on the even packing plate 8 and the packing 10 placed on the odd packing plate 9, so that the two are in contact with each other up and down, preventing the vertical unutilized situation between the upper and lower packings;

[0066] 4) Then tighten the end cap 3.

[0067] Embodiment 4,

[0068] like Figure 1 As shown, an electrostatic separator for improving filler utilization rate comprises a cylinder 1, an electrode column 2 coaxially arranged inside the cylinder 1, and a plurality of filler plates stacked horizontally inside the cylinder 1. The top of the cylinder 1 is open and the inside is hollow, and an end cap 3 threadedly connected to the cylinder 1 is provided at the top opening of the cylinder 1; an electrode column rotation groove 6 is provided at the center of the inner bottom of the cylinder 1, and the bottom end of the electrode column 2 is fixedly connected in the electrode column rotation groove 6 so that it is vertically installed in the center of the cylinder 1. The electrode column 2 is made of copper material with good electrical conductivity and serves as the anode of the entire electrostatic separator. The cylinder 1 is also made of material with good electrical conductivity and serves as the cathode of the entire electrostatic separator; at the same time, insulating material is laid in the electrode column rotation groove 6 to insulate and separate the cylindrical electrode column 2 from the cylinder 1. A packing plate slot 7 for supporting a packing plate is provided at the bottom of the inner side wall of the cylinder 1, and the packing plate is horizontally stacked on the packing plate slot 7; at the same time, one side of the radius of the bottom of the cylinder 1 protrudes downward to form a conical funnel shape (the upper end diameter of the conical funnel-shaped structure is equal to the radius of the bottom of the cylinder 1, and gradually shrinks downward), and an oil slurry outlet 5 is provided at the bottom end of the conical funnel-shaped structure, and an oil slurry inlet 4 corresponding to the oil slurry outlet 5 is provided on the upper part of the side wall of the cylinder 1, and corresponding valves are provided at the oil slurry inlet 4 and the oil slurry outlet 5 for injecting and discharging the oil slurry.

As the inner ends of the strip filling areas 12 converge, an inner angle of the conical filling area 13 is formed. A circular filling area 14 is formed between the inner angles of the multiple conical filling areas 13 and the electrode holes 15. Multiple filling placement holes 16 are provided in each strip filling area 12 and each conical filling area 13. The filling placement holes 16 in the strip filling area 12 are arranged along the radial axis of the filling plate in its length direction, and the filling placement holes 16 in the conical filling area 13 are arranged along the radial axis of the filling plate on the center line of its inner angle. Each filling placement hole 16 is used to fix the position of a filler 10. The diameter of the filling placement hole 16 is slightly smaller than the spherical diameter of the filler 10, so as to facilitate the stable placement of the filler 10. The spacing between two adjacent filling placement holes 16 on each radial axis is adjusted according to the size of the filler 10, so that the filler 10 can be closely arranged after placement.

[0070] The diameters of the even-numbered packing plates 8 and the odd-numbered packing plates 9 are equal and smaller than the inner diameter of the cylinder 1, so as to facilitate placement, installation and recovery, and facilitate the circulation and desolidification of the oil slurry. The number and distribution positions of the packing plate baffles arranged thereon are the same. The number of the packing plate baffles depends on the size of the packing 10 and the overall size of the packing plate. The number of the packing plate baffles is proportional to the size of the packing plate and inversely proportional to the size of the packing 10, and follows the following two principles: (1) the proportion of the enclosed strip packing area 12 is as large as possible, and (2) the proportion of the circular packing area 14 enclosed by the conical packing area 13 and the electrode hole 15 is as small as possible. The two principles are inversely proportional. Therefore, the number of the strip packing areas 12 to be set should be selected appropriately according to the size of the packing plate and the radius of the packing 10. The spacing width of the two baffles 11 in each group of packing plate baffles is slightly smaller than the diameter of the packing 10, and the height of the baffle 11 is slightly smaller than the radius of the packing 10, so as to fix the position of the packing 10 and prevent the packing 10 from being displaced or rolled off.

The number of filler placement holes 16 in the conical filler area 13 on the even filler plate 8 is consistent with the number of filler placement holes 16 in the conical filler area 13 on the odd filler plate 9. The filler placement holes 16 in the strip filler area 12 and the conical filler area 13 on the even filler plate 8 and the odd filler plate 9 are of the same size but in different positions, and the two are staggered, and the staggered distance is the radius of a filler 10, in order to make the center line between the upper and lower fillers 10 form an angle with the electric field line.

[0072] Furthermore, if Figure 4 As shown, the fillers 10 placed on the even-numbered filler plates 8 and the fillers 10 placed on the odd-numbered filler plates 9 can contact each other vertically, and an angle θ exists between a line connecting the centers of two adjacent fillers 10 and a vertical line, and the angle θ is 40°.
