Description

Technical Field

[0001] The present invention relates to the field of flue gas purification devices, and in particular to an electrostatic field and an installation method thereof, and a flue gas purification system. Background Art

[0002] Industrial production or large kitchens will generate a lot of smoke during operation, and the smoke cannot be discharged directly into the atmosphere to avoid pollution. Usually, during the smoke emission process, a smoke purification device is used to absorb the particulate matter or oil smoke in the smoke to ensure that the exhaust gas is clean.

[0003] Electrostatic fields are widely used in a variety of flue gas purification scenarios due to their excellent adsorption performance for oil smoke and particulate matter. However, in some electrostatic fields, such as the electrostatic field disclosed in patent number CN215541787U, one end of the insulator is fixedly connected to one side of the frame, and the other end is fixedly connected to the cathode frame. Due to the non-precision structure of the insulator, the threaded mounting holes at both ends of the insulator are difficult to be coaxial. The screw holes for installing the insulator on the cathode frame used to connect the insulator and the frame of the electrostatic field are produced according to the drawings (that is, the screw holes at both ends of the insulator are coaxial). Since the two mounting screw holes of the insulator are not coaxial, the screw holes on the cathode frame and the casing of the electrostatic field processed according to the drawings cannot install the insulator normally. Usually, the screw holes on the casing of the electrostatic field are enlarged so that the insulator can be installed normally. However, after the screw holes on the casing are enlarged, the connection between the insulator and the casing will be unstable, that is, the cathode frame connected to the insulator will be unstable, and the multiple cathode plates connected to the cathode frame may shake under the blowing of flue gas. The pole distance in the electrostatic field may change slightly during the flow of flue gas, resulting in instability of the electrostatic field.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

By installing corner protectors, the anode plate is not easily deformed by external forces. By providing a groove for limiting the anode plate inside the corner protector, the position of the anode plate is further not easily changed, thereby ensuring a stable electrode distance in the electrostatic field. The orthographic projection of the cathode plate falls within the orthographic projection range of the anode plate to avoid contact between the cathode plate and the corner protector, resulting in electrical connection between the cathode plate and the anode plate. By setting the mounting plate as a "C"-shaped mounting plate, the cathode frame that needs to be connected to the external circuit is surrounded, effectively avoiding accidental contact of the user with the charged cathode frame. By providing a first avoidance portion and a second avoidance portion, contact between the cathode plate and the anode plate is further avoided. By connecting both ends of the third fixing rod to the insulators provided on both sides thereof, it is convenient to install the insulators and at the same time a stable distance is provided between the anode plates.

[0057] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0058] Example

[0059] Electrostatic field is widely used in various dust removal environments due to its excellent dust removal performance. In order to avoid the cathode frame and the frame or the anode plate from contacting, an insulator is usually installed between the cathode frame and the mounting frame to ensure that the mounting frame is not charged.

[0060] However, in some electrostatic fields, such as the one disclosed in patent number CN215541787U, the cathode frame is set as a square tube, and the convenient side is connected to the inner side of the mounting frame by an insulator. Since the insulator is not a standard part, the axis of the mounting holes at both ends of some insulators is misaligned. When designing the cathode frame drawings, the insulator is an ideal insulator, that is, the mounting holes at both ends of the insulator are on the same axis. At this time, the mounting holes opened on the cathode frame and the mounting frame are also coaxially arranged. Since the insulator is actually a non-standard part, after one end of the insulator is installed on the cathode frame, on the basis of keeping the mounting rod on the cathode frame vertical to the mounting frame, the other end of the insulator cannot be aligned with the through hole on the mounting frame.

[0061] In order to ensure that the insulator can be installed normally, it is necessary to expand the mounting hole on the mounting frame for mounting the insulator. After the mounting hole on the mounting frame is enlarged, there is a certain gap between the bolts used to connect the insulator and the mounting block, and the bolts cannot fix the cathode frame well. When the flue gas flows between the cathode plate and the anode plate, the cathode plate fixed by the cathode frame may shift due to the unfixed position of the cathode frame, resulting in a change in the distance between the cathode plate and the anode plate, and the dust removal efficiency of the electrostatic field is greatly reduced.

[0062] The present application discloses an electrostatic field, which integrates square tubes into a plate-shaped cathode frame 40, and installs an insulator 60 between two opposite surfaces of the plate-shaped cathode frame 40 and a mounting plate 10, with one end of the insulator 60 fixedly connected to the cathode frame 40 and the other end fixedly connected to the mounting plate 10. That is, the insulator 60 is clamped by the cathode frame 40 and the mounting plate 10, and the insulator 60 is fixedly connected to the cathode frame 40 and the mounting plate 10. Figure 3 At this time, regardless of whether the mounting holes at both ends of the insulator 60 are coaxial, after the hole for mounting the insulator 60 at the mounting plate 10 or the cathode frame 40 is enlarged, the insulator 60 arranged between the plate-shaped cathode frame 40 and the mounting plate 10 can still be well clamped, and the cathode frame 40 and the cathode plate 70 mounted on the cathode frame can still remain stable during the flow of flue gas, that is, the pole distance of the electrostatic field is stable, ensuring that the electrostatic field can stably purify the flue gas.

[0063] Specifically, see Figure 1-3 The electrostatic field provided by the present invention comprises two parallel mounting plates 10, a first fixing rod 20 is arranged between the two mounting plates 10, and the two ends of the first fixing rod 20 are respectively fixedly connected to the two mounting plates 10. A plurality of mutually parallel anode plates 30 are mounted on the first fixing rod 20, and the anode plates 30 are arranged at intervals. Two cathode racks 40 are also arranged to install the cathode plate 70, and the two mounting plates 10 are arranged between the two cathode racks 40. A plurality of insulators 60 are arranged between the mounting plate 10 and the cathode rack 40, and the two ends of the insulator 60 are respectively fixedly connected to the two opposite surfaces of the mounting plate 10 and the cathode rack 40, so that the cathode rack 40 and the mounting plate 10 are parallel. A second fixing rod 50 is arranged between the two cathode racks 40, the second fixing rod 50 is arranged between the two cathode racks 40 and passes through the mounting plate 10 and the plurality of anode plates 30, and the two ends of the second fixing rod 50 are respectively fixedly connected to the two cathode racks 40, and the second fixing rod 50 is not connected to the anode plate 30. A plurality of cathode plates 70 parallel to the anode plate 30 are mounted on the second fixing rod 50, and the cathode plates 70 are installed on the second fixing rod 50 between the two mounting plates 10 at intervals. Figure 3 and Figure 4 At this time, a cathode plate 70 is disposed between two adjacent anode plates 30 and the cathode plate 70 and the first fixing rod 20 are not connected.

[0064] The cathode plate 70 and the anode plate 30 are arranged in parallel and spaced apart from each other to form the pole plate of the electrostatic field. The cathode plate 70 is connected to the cathode frame 40. When the cathode frame 40 is powered, an electrostatic field is formed between the cathode plate 70 and the anode plate 30. When the flue gas passes through the electrostatic field, the oil smoke and particulate matter in the flue gas are adsorbed on the anode plate 30 under the action of the electrostatic field.

[0065] When the insulator 60 is clamped by the cathode frame 40 and the mounting plate 10 , whether the mounting holes of the insulator 60 are coaxial will not affect the cathode frame 40 and the mounting plate 10 clamping the insulator 60 to maintain the stability of the cathode frame 40 and the mounting plate 10 .

[0066] For easy installation, the first fixing rod 20 is perpendicular to the mounting plate 10, and the anode plate 30 is parallel to the mounting plate 10. Since the insulator 60 can be polished in the length direction so that the length of the insulator 60 between the cathode frame 40 and the mounting plate 10 is consistent, the plate-shaped cathode frame 40 can be kept parallel to the mounting plate 10, and the second fixing rod 50 is also easy to install, and the second fixing rod 50 presses the cathode frame 40 against the insulator 60.

[0067] The anode plate 30 and the second fixing rod 50, and the cathode plate 70 and the first fixing rod 20 cannot be connected to each other, so as to avoid the cathode plate 70 and the anode plate 30 from being connected. Figure 8-11 As shown, a first avoidance portion 31 is provided on the anode plate 30 , and the first avoidance portion 31 is used to avoid the second fixing rod 50 . A second avoidance portion 71 is provided on the cathode plate 70 , and the second avoidance portion 71 is used to avoid the first fixing rod 20 .

[0068] The shapes of the first avoidance portion 31 and the second avoidance portion 71 are not limited, as long as the first avoidance portion 31 can avoid the second fixing rod 50 and the second avoidance portion 71 can avoid the first fixing rod 20 .

[0069] Preferably, in an embodiment of the present invention, in order to facilitate the processing of the first avoidance portion 31 and the second avoidance portion 71 , stamping is usually performed on the cathode plate 70 and the anode plate 30 , that is, circular holes are punched out on the cathode plate 70 and the anode plate 30 .

[0070] The insulators 60 are usually arranged symmetrically so that the forces on the cathode plate 70 are balanced.

[0071] Since the cathode plate 70 is relatively thin, six symmetrically arranged first avoidance portions 31 are provided on the anode plate 30 , that is, six symmetrically arranged second fixing rods 50 are provided to fix the cathode plate 70 .

[0072] In order to avoid the second fixing rod 50 , the first fixing rod 20 is disposed at the four corners of the mounting plate 10 .

[0073] In order to make the thinner anode plate 30 more stable during the flow of smoke, four symmetrical third fixing rods 80 are also provided in the middle of the anode plate 30. Both ends of the third fixing rod 80 are respectively fixedly connected to the mounting plate 10, and the third fixing rod 80 is connected to the anode plate 30 and not connected to the cathode plate 70.

[0074] Preferably, in an embodiment of the present invention, in order to ensure that the thin cathode frame 40 is stably installed, four insulators 60 are arranged between the mounting plate 10 and the cathode frame 40 .

[0075] In order to facilitate the installation of the insulator 60 , the end of the third fixing rod 80 disposed in the middle of the anode plate 30 is usually connected to the installation hole at one end of the insulator 60 .

[0076] Reference Figure 6 and Figure 7 When the cathode plate 70 or the anode plate 30 has sufficient strength, only one set of two symmetrical insulators 60 may be provided to fix the cathode plate 70. Similarly, the number of the first fixing rods 20 and the second fixing rods 50 should be reduced. In this case, when only two first fixing rods 20 are provided, the first fixing rods 20 may be directly connected to the two insulators 60.

[0077] It should be understood that the number of the insulator 60, the first fixing rod 20 (the third fixing rod 80, both of which are used to fix the anode plate 30) and the second fixing rod 50 is determined according to the strength of the cathode plate 70 and the anode plate 30. When the cathode plate 70 and the anode plate 30 are thin, the insulator 60, the first fixing rod 20 (the third fixing rod 80, both of which are used to fix the anode plate 30) and the second fixing rod 50 can be provided in several groups. When the cathode plate 70 and the anode plate 30 have sufficient strength, the insulator 60, the first fixing rod 20 (the third fixing rod 80, both of which are used to fix the anode plate 30) and the second fixing rod 50 can be provided as in the present invention. Figure 7 Set up as shown in .

[0078] In order to avoid smoke contamination of insulator 60, the cleaning cycle of the electrostatic field is shortened, combined with Figure 1 and Figure 3 Usually, the first electrode plate close to the mounting plate 10 is set as the anode plate 30, so that the mounting plate 10 does not act as the anode plate 30 to adsorb the flue gas, but also adsorbs the flue gas close to the mounting plate 10, so that the speed at which the insulator 60 is contaminated by the flue gas is slowed down, thereby extending the cleaning cycle of the entire electrostatic field.

[0079] In order to facilitate the installation of the cathode plate 70 and the anode plate 30, the first fixing rod 20, the second fixing rod 50 and the third fixing rod 80 adopt the same structure. In this application, the first fixing rod 20 is taken as an example, and the structures of the second fixing rod 50 and the third fixing rod 80 are similar to those of the first fixing rod 20, so they are not described in detail.

[0080] Reference Fig.14 The first fixing rod 20 includes a first core rod 21 and a plurality of first set rods 22, wherein the first core rod 21 passes through a plurality of anode plates 30 and both ends of the core rod are fixedly connected to the mounting plate 10 by nuts.

[0081] Specifically, threads are provided at both ends of the first core rod 21, and the outer diameter of the unthreaded section of the first core rod 21 is larger than the outer diameter of the location on the mounting plate 10 for mounting the first core rod 21. The outer diameter of the unthreaded section of the first core rod 21 is smaller than the outer diameter of the hole on the anode plate 30 for passing the first core rod 21. The first sleeve rod 22 is sleeved on the outer wall of the first core rod 21, and two adjacent first sleeve rods 22 are used to clamp the anode plate 30.

[0082] There are at least two types of lengths of the first set of rods 22 . One type of length of the first set of rods 22 is equal to the distance between the mounting plate 10 and the adjacent anode plate 30 . Another type of length of the first set of rods 22 is equal to the distance between two adjacent anode plates 30 .

[0083] Similarly, the second fixing rod 50 includes a second core rod and a second sleeve rod 52, and the third fixing rod 80 includes a third core rod and a third sleeve rod.

[0084] During installation, firstly, the first core rod 21 and the second core rod are fixed to the mounting plate 10 by nuts, then the insulator 60 and the third core rod corresponding to the mounting plate 10 on this side are fixed, and the cathode frame 40 is installed on the insulator 60 .

[0085] The lengths of the second set of rods 52 and the third set of rods are also various to suit their installation environments.

[0086] After the first core rod 21, the second core rod and the third core rod are installed, the first set rod 22 and the third set rod are placed in sequence, and then the anode plate 30 is placed. After the second set rod 52 is placed on the second core rod, the cathode plate 70 is placed on the second set rod 52.

[0087] The above steps are repeated to sequentially place the cathode plate 70 and the anode plate 30 at intervals.

[0088] Then, the first core rod 21 is fixed by nuts, the insulator 60 at the mounting plate 10 on the other side is fixed to the third core rod, the cathode plate 70 on the other side is fixed to the insulator 60, and then the second core rod is fixed to the cathode frame 40 by nuts.

[0089] In order to prevent the electrode plate from being deformed due to external interference, a corner guard 90 is usually provided between two mounting plates 10, and both ends of the corner guard 90 are fixedly connected to the two mounting plates 10 respectively. As Figure 1-2 and Figure 4 shown, the corner guard 90 wraps the corners of the anode plate 30 to prevent the anode plate 30 from being deformed by force.

[0090] The corner guard 90 is usually fixedly connected to the mounting plate 10 by a blind rivet, so as to make the electrostatic field more stable. At the same time, the blind rivet is easy to disassemble, making the electrostatic field easy to maintain.

[0091] In order to prevent the cathode plate 70 from being connected to the anode plate 30, the orthographic projection of the cathode plate 70 is located within the orthographic projection range of the anode plate 30, so that the cathode plate 70 and the corner guard 90 will not come into contact.

[0092] Furthermore, in order to make the corner guard 90 have a better protection effect on the anode plate 30, as Figure 12-13 shown, the corner guard 90 is provided with grooves 91 adapted to the number of anode plates 30, and the grooves 91 are used to limit the anode plate 30. That is, the width of the groove 91 is slightly larger than the thickness of the anode plate 30, so as to well constrain the anode plate 30 and make the pole pitch of the electrostatic field stable.

[0093] Referring to Figure 4 or Figure 6 , the mounting plate 10 is usually set as a "C"-shaped mounting plate 10, and the cathode holder 40 is arranged inside the opening of the mounting plate 10, so as to enhance the rigidity of the mounting plate 10. At the same time, the non-charged mounting plate 10 surrounds the charged cathode holder 40 to prevent personnel from accidentally touching it.

[0094] As Figure 5 shown, in order to facilitate the handling of the electrostatic field, a handle part is provided on the cathode holder 40, and the sheet metal at the handle part is bent inward, so that the sheet metal at this place will not cut hands.

[0095] The present invention also discloses an installation method of an electrostatic field, which is used to install the electrostatic field as described above. The method includes:

[0096] Step S1): Take a mounting plate 10, fixedly connect one end of the first core rod 21 to one side of the mounting plate 10, fixedly connect one end of the insulator 60 to the opposite side of the mounting plate 10, fixedly connect the cathode plate 70 to the other end of the insulator 60, and then pass one end of the second core rod through the mounting plate 10 and fixedly connect it to the cathode plate 70;

[0097] Step S2): Successively place the first sleeve rod 22 and the anode plate 30 on the first core rod, place the second sleeve rod 52 and the cathode plate 70 on the second core rod, and place one anode plate 30 after placing each cathode plate 70;

[0098] Step S3): another mounting plate 10 is fixedly connected to the other end of the first core rod 21;

[0099] Step S4): Take a corner protector 90 and connect the two ends of the corner protector 90 to the two mounting plates 10 respectively;

[0100] Step S5): fix the insulator 60 on another mounting plate 10 , and after the insulator 60 is installed, install another cathode frame 40 on the insulator 60 .

[0101] Specifically, threads are provided at both ends of the first core rod 21, and the outer diameter of the unthreaded section of the first core rod 21 is larger than the outer diameter of the location on the mounting plate 10 for mounting the first core rod 21. The outer diameter of the unthreaded section of the first core rod 21 is smaller than the outer diameter of the hole on the anode plate 30 for passing the first core rod 21. The first sleeve rod 22 is sleeved on the outer wall of the first core rod 21, and two adjacent first sleeve rods 22 are used to clamp the anode plate 30.
