Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly relates to an integrated self-cleaning and environment-friendly industrial waste gas treatment device. Background Art

[0002] With the acceleration of the industrialization process, the emissions of industrial waste gas are increasing day by day. If the particulate matter contained in industrial waste gas is directly discharged into the atmosphere without effective treatment, it will bring many serious hazards. For example, particulate matter, especially fine particulate matter, can penetrate deep into the human lungs and cause lung diseases and cardiovascular diseases.

[0003] Currently, the equipment commonly used to remove particulate matter from industrial waste gas includes bag filters, electrostatic precipitators, wet scrubbers, and cyclone dust collectors. For fine particulate matter, electrostatic precipitators are currently used more frequently. It has the advantages of high dust removal efficiency, especially good removal effect on fine particulate matter, small resistance, low energy consumption, and can handle waste gas at high temperature and high pressure. However, in actual use, the particulate matter is concentrated on the dust collecting electrode. If the content of particulate matter in the waste gas is large, when a certain thickness of dust layer accumulates on the dust collecting electrode, it will affect the dust removal efficiency and normal operation of the equipment. Therefore, it is necessary to frequently stop the machine to deal with the dust on its dust collecting electrode, which is inconvenient to use in the scenarios with a large amount of waste gas treatment or a large content of particulate matter in the waste gas. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated self-cleaning and environment-friendly industrial waste gas treatment device, which solves the problem that when the content of particulate matter in the waste gas is large, the electrostatic precipitator needs to be frequently stopped for cleaning in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An integrated self-cleaning and environment-friendly industrial waste gas treatment device, including an outer box and dust collecting electrodes and corona electrodes evenly distributed inside the outer box. An air inlet pipe and an exhaust pipe are respectively arranged on both sides of the outer box. A plurality of cages are arranged in an array in the middle of the inner part of the outer box. An activity groove is arranged on the cage. There is a group of activity grooves on the outermost cage and they are located inside the cage. There are two groups of activity grooves on the middle cages and they are respectively located on both sides of the cage. The dust collecting electrodes are slidably arranged in the activity grooves. The dust collecting electrodes between adjacent two groups of cages are fixedly connected by a connecting frame. The corona electrodes are arranged between adjacent two groups of cages and are located between two groups of dust collecting electrodes. A collecting hopper is arranged below the inner part of the outer box, and the top of the collecting hopper corresponds to the bottom of the cage;

[0006] Inside the outer box, an upper fixing frame is provided at the top of the cage. The upper fixing frame is fixedly connected to the cage. A plurality of knocking and resetting mechanisms are evenly distributed on the upper fixing frame. The knocking and resetting mechanism includes a movable rod slidably connected to the upper fixing frame up and down. The bottom of the movable rod is fixedly connected to a connecting frame. The top of the movable rod is fixedly connected to a limiting block. A reset spring is sleeved outside the movable rod, and the reset spring is located between the top of the upper fixing frame and the limiting block.

[0007] Above the inside of the outer box, a position adjusting mechanism and a dust cleaning mechanism are further provided. Plugging mechanisms are arranged at the front and back inside the outer box, and there are two groups of plugging mechanisms. The dust cleaning mechanism corresponds to the knocking and resetting mechanism and is used to knock the knocking and resetting mechanism to vibrate the dust collecting electrode to shake off particulate matter. The dust cleaning mechanism is also used to adjust the gap between the two groups of plugging mechanisms. The plugging mechanism is used to fit between adjacent two cages, so that the shaken-off particulate matter can smoothly enter the collection hopper, facilitating the dust on the corona electrode between the two cages to fall into the collection hopper. The position adjusting mechanism is used to adjust the positions of the dust cleaning mechanism and the plugging mechanism so that the dust cleaning mechanism and the plugging mechanism correspond to different cages.

[0008] Further, a first sealing plate and a second sealing plate are provided above the inside of the outer box. The second sealing plate and the first sealing plate are located at the front and back of the top of the cage and are fixedly connected to the cage. A first slide rail is provided at the top of the second sealing plate.

[0009] Further, the position adjusting mechanism includes a servo motor fixedly connected above the inside of the outer box. The output end of the servo motor is fixedly connected to a lead screw. A movable frame is threadedly connected to the outside of the lead screw. The movable frame is slidably connected above the second sealing plate through the first slide rail. The top of the movable frame is fixedly connected to a housing. By starting the servo motor to drive the lead screw to rotate, the movable frame and the housing can be driven to slide left and right.

[0010] Further, the top of the corona electrode is fixedly connected to the first sealing plate and the second sealing plate. The corona electrode is connected to the negative pole of a high-voltage DC power supply, and the dust collecting electrode is connected to the positive pole of the high-voltage DC power supply. By connecting the negative pole, a strong electric field is formed around the corona electrode, so that gas molecules are ionized, making dust particles charged. The charged dust particles move towards the dust collecting electrode under the action of the electric field force and finally deposit on the dust collecting electrode.

[0011] Furthermore, the dust cleaning mechanism includes a double-headed motor fixedly arranged inside the housing. The two output ends of the double-headed motor are fixedly connected with a rotating shaft. A knocking block is fixedly connected to the rotating shaft. The knocking block is used to squeeze the limiting block. When the knocking block squeezes the limiting block, the dust collecting electrode is driven to move downward through the movable rod and the connecting frame. After moving, it is reset under the action of the return spring, and then the knocking block squeezes again, so as to drive the dust collecting electrode to vibrate up and down reciprocally. When the dust collecting electrode vibrates up and down, the power supplies of both the dust collecting electrode and the corona electrode are disconnected. The dust cleaning mechanism further includes a threaded rod fixedly connected to the end of the rotating shaft far away from the double-headed motor. A sliding plate is threadedly connected to the threaded rod. Limit blocks are installed at the ends of the sliding plate to prevent the sliding plate from disengaging from the outer end of the threaded rod. The minimum diameter of the threaded groove on the sliding plate is the same as the diameter of the rotating shaft. When the threaded rod rotates, the two groups of sliding plates approach each other and finally can disengage from the threaded rod and enter the outside of the rotating shaft. At this time, the rotation of the rotating shaft will not drive the sliding plates to approach each other, but the rotating shaft can drive the knocking block to perform a knocking motion.

[0012] Furthermore, limiting grooves corresponding to the sliding plates are arranged on both sides inside the housing, and the limiting grooves open downward. A dust-proof sheet is fixedly connected to the outside of the sliding plate. The dust-proof sheet is used to block the lower opening of the limiting groove to prevent dust from entering. Second slide rails are further arranged on the tops of the first sealing plate and the second sealing plate. A guiding block is slidably connected inside the second slide rail. A guiding shaft is slidably connected to the guiding block. The guiding shaft is fixedly connected to the inner side of the sliding plate. The second slide rail, the guiding block and the guiding shaft are used to guide the sliding plate.

[0013] Furthermore, the blocking mechanism is fixedly connected to the bottom of the sliding plate. A sliding groove is arranged inside the blocking mechanism. The blocking mechanism further includes a blocking plate slidably connected in the sliding groove. The blocking plate is used to fit on the outside of two adjacent cages. Under the action of the upper fixing frame, the first sealing plate and the second sealing plate, a chamber with an open bottom is formed between two adjacent cages. At this time, the vibrating particulate dust will fall into the collecting hopper. A compression spring is fixedly installed between the inner wall of the sliding groove and the blocking plate. An air vent communicating with the inside of the sliding groove is arranged on the outside of the fixing plate. The function of the compression spring is to increase the fitting degree of the blocking plate and the cage and improve its sealing performance. When the double-headed motor drives the rotating shaft to rotate in the reverse direction, under the reset action of the blocking plate, the sliding plate can be smoothly combined with the threaded rod outside the rotating shaft, and the two groups of sliding plates can smoothly move outward and separate from the cage.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] An integrated self-cleaning and environmentally friendly industrial waste gas treatment device provided by the present invention enables the dust collecting electrode to be slidably arranged and the adjacent dust collecting electrodes to move synergistically by setting a cage, a movable groove and a connecting frame structure. An upper fixing frame and a knocking and resetting mechanism are arranged on the top of the cage. When cleaning is required, the knocking block of the ash cleaning mechanism presses the limiting block, and drives the dust collecting electrode to vibrate up and down reciprocally through the movable rod and the connecting frame, so as to shake off the particulate matter on the surface of the dust collecting electrode. Moreover, the first sealing plate, the second sealing plate and the plugging mechanism provided can seal the cleaning area during the cleaning process. Through the adjustment of the position adjustment mechanism on the ash cleaning mechanism and the plugging mechanism, the cleaning of all the dust collecting electrodes is realized. During the whole cleaning process, the cleaning is realized without stopping the machine, with high continuity and good dust removal effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] In order to solve the technical problem that when the particulate matter content in the waste gas is large, the electrostatic precipitator needs to be frequently shut down for cleaning, as Figures 1 - 9 shown, the following preferred technical solutions are provided:

[0028] As Figures 1 - 5 shown, an integrated self-cleaning and environmentally friendly industrial waste gas treatment device includes an outer box 1 and dust collecting electrodes 5 and corona electrodes 6 evenly distributed inside the outer box 1. An air inlet pipe 2 and an exhaust pipe 3 are respectively arranged on both sides of the outer box 1. The exhaust pipe 3 is externally connected to a fan. A cage 4 is arranged in the middle of the inner part of the outer box 1 in an array. A movable slot 41 is arranged on the cage 4. There is a group of movable slots 41 on the outermost cage 4 and they are located inside the cage 4. There are two groups of movable slots 41 on the middle cage 4 and they are respectively located on both sides of the cage 4. The dust collecting electrode 5 is slidably arranged in the movable slot 41. The dust collecting electrodes 5 between adjacent two groups of cages 4 are fixedly connected through a connecting frame 51. The corona electrode 6 is arranged between adjacent two groups of cages 4 and is located between the two dust collecting electrodes 5. A collection hopper 17 is arranged below the inner part of the outer box 1. The top of the collection hopper 17 corresponds to the bottom of the cage 4;

[0029] Inside the outer box 1, an upper fixing frame 11 is arranged at the top of the cage 4. The upper fixing frame 11 is fixedly connected to the cage 4. A knocking and resetting mechanism 16 is evenly distributed on the upper fixing frame 11. The knocking and resetting mechanism 16 includes a movable rod 161 slidably connected up and down on the upper fixing frame 11. The bottom of the movable rod 161 is fixedly connected to the connecting frame 51. A limiting block 162 is fixedly connected to the top of the movable rod 161. A reset spring 163 is sleeved outside the movable rod 161, and the reset spring 163 is located between the top of the upper fixing frame 11 and the limiting block 162.

[0030] As Figures 6 - 7 shown, a position adjusting mechanism 7 and a dust cleaning mechanism 8 are further arranged above the inside of the outer box 1. Sealing mechanisms 9 are arranged at the front and rear of the inside of the outer box 1, and there are two groups of sealing mechanisms 9. The dust cleaning mechanism 8 corresponds to the knocking and resetting mechanism 16, and is used to knock the knocking and resetting mechanism 16 to make the dust collecting electrode 5 vibrate to shake off particulate matter. The dust cleaning mechanism 8 is also used to adjust the gap between the two groups of sealing mechanisms 9. The sealing mechanism 9 is used to fit between adjacent two cages 4, so that the shaken-off particulate matter can smoothly enter the collecting hopper 17, facilitating the dust on the corona electrode 6 between the two cages 4 to fall into the collecting hopper 17. The position adjusting mechanism 7 is used to adjust the positions of the dust cleaning mechanism 8 and the sealing mechanism 9, so that the dust cleaning mechanism 8 and the sealing mechanism 9 correspond to different cages 4.

[0031] As Figure 4 and Figure 6 shown, a first sealing plate 12 and a second sealing plate 13 are arranged above the inside of the outer box 1. The second sealing plate 13 and the first sealing plate 12 are located at the front and rear of the top of the cage 4 and are fixedly connected to the cage 4. A first slide rail 14 is arranged at the top of the second sealing plate 13.

[0032] As Figure 7 shown, the position adjusting mechanism 7 includes a servo motor 71 fixedly connected above the inside of the outer box 1. The output end of the servo motor 71 is fixedly connected to a lead screw 72. A movable frame 73 is threadedly connected to the outside of the lead screw 72. The movable frame 73 is slidably connected above the second sealing plate 13 through the first slide rail 14. A housing 74 is fixedly connected to the top of the movable frame 73. By starting the servo motor 71 to drive the lead screw 72 to rotate, the movable frame 73 and the housing 74 can be driven to slide left and right.

[0033] The top of the corona electrode 6 is fixedly connected to the first sealing plate 12 and the second sealing plate 13. The corona electrode 6 is connected to the negative pole of a high-voltage DC power supply, and the dust collecting electrode 5 is connected to the positive pole of the high-voltage DC power supply. By connecting the negative pole, a strong electric field is formed around the corona electrode 6, so that gas molecules are ionized, enabling dust particles to be charged. The charged dust particles move towards the dust collecting electrode 5 under the action of the electric field force and finally deposit on the dust collecting electrode.

[0034] As Figure 8As shown, the dust cleaning mechanism 8 includes a double-headed motor 81 fixedly arranged inside the housing 74. Two output ends of the double-headed motor 81 are fixedly connected with a rotating shaft 82. A knocking block 83 is fixedly connected to the rotating shaft 82. The knocking block 83 is used to squeeze the limiting block 162. When the knocking block 83 squeezes the limiting block 162, the dust collecting electrode 5 is driven to move downward through the movable rod 161 and the connecting frame 51. After moving, it is reset under the action of the return spring 163. Subsequently, the knocking block 83 squeezes again, thereby driving the dust collecting electrode 5 to vibrate up and down reciprocally. When the dust collecting electrode 5 vibrates up and down, both the dust collecting electrode 5 and the corona electrode 6 are powered off. The dust cleaning mechanism 8 further includes a threaded rod 84 fixedly connected to the end of the rotating shaft 82 away from the double-headed motor 81. A sliding plate 85 is threadedly connected to the threaded rod 84. Limit blocks are installed at the ends of the sliding plate 85. The limit blocks are used to prevent the sliding plate 85 from disengaging from the outer end of the threaded rod 84. The minimum diameter of the threaded groove on the sliding plate 85 is the same as the diameter of the rotating shaft 82. When the threaded rod 84 rotates, the two sliding plates 85 approach each other and finally can disengage from the threaded rod 84 and enter the outside of the rotating shaft 82. At this time, the rotation of the rotating shaft 82 will not drive the sliding plates 85 to approach each other, while the rotating shaft 82 can drive the knocking block 83 to perform a knocking motion.

[0035] As Figures 7 - 8 shown, limiting grooves 75 corresponding to the sliding plates 85 are arranged on both sides inside the housing 74, and the limiting grooves 75 open downward. A dust-proof sheet 851 is fixedly connected to the outside of the sliding plate 85. The dust-proof sheet 851 is used to block the lower opening of the limiting groove 75 to prevent dust from entering. As Figure 6 shown, a second slide rail 15 is further arranged on the tops of the first sealing plate 12 and the second sealing plate 13. As Figure 8 shown, a guiding block 852 is slidably connected inside the second slide rail 15. A guiding shaft 853 is slidably connected to the guiding block 852. The guiding shaft 853 is fixedly connected to the inner side of the sliding plate 85. The second slide rail 15, the guiding block 852 and the guiding shaft 853 are used to guide the sliding plate 85.

[0036] As Figures 8 - 9As shown, the plugging mechanism 9 is fixedly connected to the bottom of the sliding plate 85. A sliding groove 911 is provided inside the plugging mechanism 9. The plugging mechanism 9 further includes a plugging plate 93 slidably connected in the sliding groove 911. The plugging plate 93 is used to fit against the outside of two adjacent sets of cages 4. Under the action of the upper fixing frame 11, the first sealing plate 12 and the second sealing plate 13, a chamber with an open bottom is formed between two adjacent sets of cages 4. At this time, the vibrating particulate dust will fall into the collection hopper 17. A compression spring 92 is fixedly installed between the inner wall of the sliding groove 911 and the plugging plate 93. An air vent 912 communicating with the inside of the sliding groove 911 is provided outside the fixing plate 91. The function of the compression spring 92 is to increase the degree of fit between the plugging plate 93 and the cage 4 and improve its sealing performance. When the double-headed motor 81 drives the rotating shaft 82 to rotate in the reverse direction, under the reset action of the plugging plate 93, the sliding plate 85 can smoothly engage with the threaded rod 84 outside the rotating shaft 82, and the two sliding plates 85 can smoothly move outward and separate from the cage 4.

[0037] Specifically, the working principle of the present invention is as follows: During normal operation, the two plugging mechanisms 9 do not contact the cage 4. When the waste gas passes through the outer box 1, the corona electrode 6 forms a strong electric field around it, thereby ionizing gas molecules and charging dust particles. The charged dust particles move towards the dust collecting electrode 5 under the action of the electric field force and finally deposit on the dust collecting electrode 5. When the particulate matter deposited on the dust collecting electrode 5 is too much and affects its normal dust removal effect, the position adjustment mechanism 7 is started to adjust the positions of the dust cleaning mechanism 8 and the plugging mechanism 9. Subsequently, the double-headed motor 81 is started. When the double-headed motor 81 rotates forward, under the action of the rotating shaft 82, the threaded rod 84 and the sliding plate 85, the two plugging mechanisms 9 approach each other and fit against the front and back of two adjacent sets of cages 4. The dust collecting electrode 5 and the corona electrode 6 between these two sets of cages 4 are powered off. As the double-headed motor 81 rotates, the sliding plate 85 leaves the threaded rod 84 and enters the outer range of the rotating shaft 82. At this time, the double-headed motor 81 continues to rotate, and the knocking block 83 quickly knocks the knocking and resetting mechanism 16 to vibrate the dust collecting electrode 5 up and down, so that the particulate matter on the surface of the dust collecting electrode 5 falls into the collection hopper 17. Subsequently, the double-headed motor 81 rotates in the reverse direction. Under the reset action of the plugging plate 93 and the reverse rotation of the rotating shaft 82 and the threaded rod 84, the sliding plate 85 smoothly enters the threaded rod 84 and drives the plugging mechanisms 9 to move away from each other. Subsequently, the position is adjusted through the position adjustment mechanism 7 to clean the dust on the dust collecting electrode 5 inside all the cages 4, realizing cleaning without stopping the machine, with high persistence and good dust removal effect.

[0038] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0039] As described above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
