Description

Technical Field

[0001] The utility model relates to an electrostatic precipitator with a transversely movable electrode, belonging to the technical field of electrostatic precipitators. Background Art

[0002] Conventional electrostatic precipitators of old units usually use a porous air flow distribution plate at the inlet horn. The purpose of uniform airflow is achieved by reasonably setting the opening rate of different areas of the distribution plate, so that the airflow entering the electrostatic precipitator is more uniform, thereby improving dust removal efficiency and avoiding local dust accumulation, wear and excessive local load.

[0003] In order to improve the dust collection efficiency of the fixed electrodes of conventional electrostatic precipitators, the existing technical solutions usually involve arranging a pre-charging device or a pre-dust collection device upstream of the fixed electrodes of the conventional electrostatic precipitator.

[0004] However, the current method of arranging pre-charging devices only plays a pre-charging role and fails to pre-collect dust first to more effectively improve the dust removal efficiency. The existing method of arranging pre-dust collection devices has the problem that the anode system cleaning effect is not ideal, especially for low-temperature electrostatic precipitators. SCR denitrification and the increase of sulfur trioxide concentration in the flue gas cause the dust to adsorb sulfur trioxide, resulting in increased dust viscosity. Under conditions with high dust viscosity and the presence of ammonium salts such as ammonium bisulfate, it is difficult to completely clean the dust by mechanical vibration alone, and it will cause the dust removal efficiency of the electric field to decrease and even affect normal operation.

[0005] An ultra-low emission electrostatic precipitator disclosed in the Chinese utility model patent with publication number CN114798175A includes an inlet end, several dust removal electric fields, and an outlet end arranged in sequence along the flue gas treatment direction, a cathode system and an anode system arranged in each dust removal electric field, and an ash hopper arranged at the bottom of each dust removal electric field. A pre-dust removal flow equalization device is provided inside the inlet end, and a corrugated pre-dust collection mechanism is provided on the pre-dust removal flow equalization device. The corrugated pre-dust collection mechanism includes several groups of corrugated sheets arranged at intervals along the width direction of the electric field, and there is an airflow channel between adjacent corrugated sheets. Each corrugated sheet includes a V-shaped mesh and an airflow diverging mesh arranged at the rear end of the V-shaped mesh and bent outward to extend. The cathode system is respectively provided with at least one mesh auxiliary electrode cathode assembly at the front end and the tail end of each electric field.

[0006] The above-mentioned reference example is provided with a pre-dust removal and flow equalization device inside the inlet end, and a corrugated pre-dust collection mechanism is provided on the pre-dust removal and flow equalization device, so that it has a pre-dust removal function at the inlet end. However, the corrugated sheets of the corrugated pre-dust collection mechanism are difficult to clean when the dust is highly sticky, which will cause the dust removal efficiency of the device to decrease. Therefore, improvement is urgently needed. Utility Model Content

[0011] A brushing mechanism for cleaning dust on the anode plate is provided on one side of each anode surround assembly close to the opening end of the inlet horn, and a driving system for driving the anode surround assembly to continuously rotate is also provided in the inlet horn.

[0012] Furthermore, an external high-pressure gas blowing device is provided on the outer side of the anode surround assembly near the inlet side of the inlet horn. The blowing device is fixedly set on the bottom plate of the inlet horn, and the blowing direction of the nozzle of the blowing device is set parallel to the bottom plate of the inlet horn.

[0013] Furthermore, chains adapted to the shape of the anode surround assembly are fixed at both ends of the anode surround assembly, two rotating shafts for supporting the anode surround assembly are sleeved inside the anode surround assembly, and an engaging sprocket engaged with the chain is fixedly sleeved on the rotating shaft, and both ends of the rotating shaft are rotatably connected to the side panels of the imported horn and the rotating shaft is driven to rotate by the drive system.

[0014] Furthermore, the cleaning mechanism includes a rotating brush assembly and a power mechanism, the rotating brush assembly includes a first cleaning brush arranged on the inner ring of the anode surround assembly and a second cleaning brush arranged on the outer end of the anode surround assembly, the first cleaning brush is fixedly sleeved with a first gear, the second cleaning brush is fixedly sleeved with a second gear meshing with the first gear, and the power mechanism is transmission-connected to the first cleaning brush or the second cleaning brush.

On the basis of the existing electrostatic precipitator, there is no need to remove a part of the original fixed electrode. It is only necessary to remove part of the equalizing plate inside the inlet horn and then add a new mobile electrode. The amount of removal and modification is small. At the same time, through the setting of the cleaning mechanism, the dust is first swept to the bottom plate of the inlet horn, and then slides into the ash hopper under the action of gravity. At the same time, high-pressure gas is used to spray the bottom plate regularly to prevent dust accumulation, thereby effectively solving the problem of poor cleaning effect of the pre-dust collection plate.

DETAILED DESCRIPTION

[0036] The present invention will be described in more detail below with reference to the embodiments.

[0037] See also Figures 1 to 15The electrostatic precipitator with a transversely movable electrode in this embodiment includes a precipitator body, which includes a shell 4. The two ends of the shell 4 are respectively connected to an inlet horn 1 and an outlet horn 5. The flow direction of the flue gas is from the inlet horn 1 to the outlet horn 5. A fixed electrode 3 is provided inside the shell 4. Five groups of ash hoppers 6 are also provided at the bottom of the shell 4. The five groups of ash hoppers 6 are arranged in sequence along the length direction of the shell 4 for collecting dust. The fixed electrode 3 is cleaned by a conventional vibrating device.

[0038] See also Figure 5 、 Figure 6 and Figure 7 A mobile electrode assembly 2 is provided in the inlet speaker 1. The mobile electrode assembly 2 includes two electrode units which are arranged inward at intervals from the inlet of the inlet speaker 1, namely a primary electrode unit and a secondary electrode unit. The primary electrode unit is arranged close to the inlet side of the inlet speaker 1.

[0039] Both electrode units include a cathode system 21 and an anode system 22 that cooperate with each other to generate an electric field. The flue gas first enters the mobile electrode assembly 2 through the inlet horn 1, and the dust in the flue gas moves to the anode system 22 under the action of the electric field force.

[0040] Specifically, see Figure 8 and Figure 9 The anode system 22 includes an anode surround assembly 233 arranged perpendicular to the flue gas flow direction and having a rectangular ring structure. The anode surround assembly 233 includes a plurality of anode plates 2332 flexibly connected end to end. Each anode plate 2332 is provided with a plurality of through holes. The spacing between two adjacent anode surround assemblies 233 is 300 to 520 mm, and the vertical distance between the bottom end of the anode surround assembly 233 and the bottom plate of the ash hopper 6 is ≥150 mm.

[0041] The opening ratios of different areas of the anode plate 2332 can be adjusted according to actual needs, so that the flue gas can smoothly enter the downstream position of the device through the through holes on the anode plate 2332.

[0042] Each anode surround assembly 233 is provided with a brushing mechanism 23 on one side close to the open end of the inlet horn 1 for cleaning dust on the anode plate 2332. The inlet horn 1 is also provided with a driving system 20 for driving the anode surround assembly 233 to continuously rotate.

[0043] In this embodiment, the anode surround assembly 233 rotates at a speed of 0.5 m / min to 1.5 m / min.

[0044] Furthermore, a blowing device 7 for external high-pressure gas is provided on the outer side of the anode surround assembly 233 near the inlet side of the inlet horn 1. The blowing device 7 is fixedly arranged on the bottom plate of the inlet horn 1, and the blowing direction of the nozzle of the blowing device 7 is arranged parallel to the bottom plate of the inlet horn 1. The high-pressure gas sprayed by the blowing device 7 causes a part of the dust to undergo a short period of intense friction and collision, thereby achieving dust cleaning in the blowing direction of the blowing device 7.

[0045] See also Figure 8 and Figure 9 Both ends of the anode surround assembly 233 are fixed with chains 222 that are adapted to the shape of the anode surround assembly 233. Two rotating shafts 231 for supporting the anode surround assembly 233 are sleeved inside the anode surround assembly 233. An engaging sprocket 2331 that engages with the chain 222 is fixedly sleeved on the rotating shaft 231. Both ends of the rotating shaft 231 are rotatably connected to the side panels of the imported speaker 1 and the rotating shaft 231 is driven to rotate by the drive system 20.

[0046] Specifically, the drive system 20 includes a first motor 232, which is arranged outside the inlet speaker 1. A motor sprocket 224 is fixedly sleeved on the output shaft of the first motor 232, and a first anode sprocket group 223 and a drive sprocket 238 are sleeved on the rotating shaft 231 corresponding to the top of the first electrode unit, and a second anode sprocket group 221 is sleeved on the rotating shaft 231 corresponding to the top of the second electrode unit, wherein the first anode sprocket group 223 and the second anode sprocket group 221 are both arranged outside the inlet speaker 1, and a bearing is arranged between the rotating shaft 231 and the inlet speaker 1.

[0047] Among them, the first-level anode sprocket group 223 includes two first-level anode sprockets installed at both ends of the rotating shaft 231 corresponding to the top of the first-level electrode unit, and the second-level anode sprocket group 221 includes two second-level anode sprockets installed at both ends of the rotating shaft 231 corresponding to the top of the second-level electrode unit. Each first-level anode sprocket and each second-level anode sprocket are arranged outside the inlet horn 1, and the first-level anode sprocket and the second-level anode sprocket arranged on the same side are connected by a chain 222.

[0048] In particular, when three or more electrode units are arranged, the number of sprockets increases sequentially, and all of them are sequentially connected through the chain 222 .

[0049] In this embodiment, the output shaft of the first motor 232 drives the motor sprocket 1 224 to rotate through the coupling.

[0050] The first motor 232 serves as a power source, and the drive sprocket 238 and the motor sprocket 1 224 are connected by the chain 222. At the same time, the first anode sprocket group 223 and the second anode sprocket group 221 are connected by the chain 222. When the first motor 232 is started, the motor sprocket 1 224, the drive sprocket 238, the rotating shaft 231 close to the inlet side of the import speaker 1, the first anode sprocket group 223, the second anode sprocket group 221 and the rotating shaft 231 away from the inlet side of the import speaker 1 can be driven to rotate in sequence, so that the first electrode unit and the second electrode unit can be driven to rotate at the same time by the first motor 232 as a power source, and when adding electrode units, it is only necessary to set up the corresponding sprocket transmission mechanism, which is quick and convenient.

[0051] See also Figure 10 、 Figure 11 and Figure 12 The cleaning mechanism 23 includes a rotating brush assembly 225 and a power mechanism. The rotating brush assembly 225 includes a first cleaning brush 2251 arranged on the inner ring of the anode surround assembly 233 and a second cleaning brush 2252 arranged on the outer end of the anode surround assembly 233. A first gear 236 is fixedly provided on the first cleaning brush 2251, and a second gear 237 meshing with the first gear 236 is fixedly provided on the second cleaning brush 2252. The power mechanism is connected to the first cleaning brush 2251 or the second cleaning brush 2252 in transmission.

[0052] Specifically, in this embodiment, both ends of the first cleaning brush 2251 and both ends of the second cleaning brush 2252 are coaxially fixedly connected with a connecting shaft 240, the first gear 236 and the second gear 237 are respectively fixedly mounted on the two connecting shafts 240, and the connecting shaft 240 rotates and passes through the inlet horn 1, and a bearing is also arranged between the connecting shaft 240 and the inlet horn 1.

[0053] In this embodiment, the power mechanism includes a second motor 226 and a motor sprocket 2241 that is transmission-connected to the second motor 226. The motor sprocket 2241 is transmission-connected to one of the connecting shafts 240 corresponding to the primary electrode unit and the secondary electrode unit through the chain 222, that is, when the second motor 226 is started, the motor sprocket 2241 can be driven to rotate. When the motor sprocket 2241 rotates, the connecting shaft 240 can be driven to rotate through the chain 222. The rotation of the connecting shaft 240 drives the first cleaning brush 2251 or the second cleaning brush 2252 to rotate, and then the first cleaning brush 2251 and the second cleaning brush 2252 can be driven to move in opposite directions through the first gear 236 and the second gear 237 that are meshed with each other, so that the first cleaning brush 2251 and the second cleaning brush 2252 can better clean the anode plate 2332.

[0054] In this embodiment, the output shaft of the second motor 226 drives the second motor sprocket 2241 to rotate through a coupling.

[0055] Since two electrode units are provided in this embodiment, two cleaning mechanisms 23 are also provided accordingly, and the number of electrode units corresponds to the number of cleaning mechanisms 23 .

[0056] Therefore, the output end of the second motor 226 is connected to two motor sprockets 2241, and the motor sprockets 2241 are respectively connected to the sprockets installed on the two connecting shafts 240 of the two brush cleaning mechanisms 23 through the chain 222, that is, the movement of the two brush cleaning mechanisms 23 is driven by the second motor 226.

[0057] When an electrode unit is added, a second motor sprocket 2241 is added to be connected to the output end of the second motor 226 , and then connected to the newly added second motor sprocket 2241 through the chain 222 .

[0058] See also Figure 11 In this embodiment, the tangential velocity direction of the contact surface between the rotating brush assembly 225 and the anode plate 2332 is opposite to the movement direction of the anode plate 2332, so as to more smoothly clean the dust on the anode plate 2332.

[0059] See also Figure 13 、 Figure 14 and Figure 15 The cathode system 21 includes a cathode frame 215 arranged in the inner circle of the anode surround assembly 233. A certain number of cathode wires are arranged in the cathode frame 215. The cathode wires can be needle wires, thorn wires, star wires, spiral wires, sawtooth wires, light rods, etc. At the same time, the cathode system 21 uses an existing vibrating device for cleaning.

[0060] The top rod of the cathode frame 215 extends to both sides of the imported speaker 1 and passes through the imported speaker 1 and is connected to a conductive component of an external high-voltage power supply. The conductive component is provided with a protective component connected to the imported speaker 1 on its outer shell.

[0061] Specifically, the conductive component includes a connecting rod 214, and two insulating components 213 are arranged inside the insulation box 211. The two insulating components 213 are fixedly sleeved with a vertically arranged connecting rod 214, and a horizontally arranged connecting rod 214 is fixedly connected between the two vertically arranged connecting rods 214. The top rod of each cathode frame 215 is extended into the insulation box 211 and connected to the horizontally arranged connecting rod 214, and the vertically arranged connecting rod 214 is connected to an external high-voltage power supply, so that a high-voltage electric field is formed between the cathode system 21 and the anode system 22.

[0062] Furthermore, the protection component includes an insulation box 211 and a protection sleeve 212. One end of the protection sleeve 212 is inserted into the insulation box 211, and the other end of the protection sleeve 212 is inserted into the imported speaker 1. The protection sleeve 212 is sleeved on the outside of the top rod of the cathode frame 215. The protection sleeve 212 serves to connect the insulation box 211 and the imported speaker 1. At the same time, it protects the top rod of the cathode frame 215 from being affected by adverse conditions outside the imported speaker 1.

[0063] In particular, a cathode system 21 is provided between any two adjacent electrode units. In this embodiment, a cathode frame 215 is provided between the primary electrode unit and the secondary electrode unit.

[0064] In particular, the movable electrode assembly 2 may also be arranged between the fixed electrode 3 and the outlet horn 5 or inside the outlet horn 5 to more effectively solve the problem of secondary dust emission after the fixed electrode 3 is vibrated.

[0065] The working principle of the present invention is as follows: dust enters the inlet horn 1 along with the flue gas, and the flue gas first passes through the mobile electrode assembly 2 arranged in the inlet horn 1. Under the action of the electric field force, most of the dust is collected by the porous mesh anode plate 2332 perpendicular to the airflow direction, and under the cleaning action of the rotating brush assembly 225 arranged under the anode plate 2332, the dust is first swept to the bottom plate of the inlet horn 1, and then slides into the ash hopper 6 under the action of gravity. At the same time, high-pressure gas is used to periodically blow the bottom plate to prevent dust accumulation, thereby effectively solving the problem of poor cleaning effect of the pre-dust collection plate.

[0066] At the same time, the treated flue gas enters the downstream fixed electrode 3 evenly under the action of the airflow uniformity of the porous mesh anode plate 2332. At this time, the amount of dust has been significantly reduced, and the processing pressure of the fixed electrode 3 is reduced, which reduces the amount of dust entering the fixed electrode 3 from the source, and significantly improves the dust accumulation situation.

[0067] The dust entering the fixed electrode 3 is further collected to the anode plate of the fixed electrode 3 under the action of the electric field force, and falls to the ash hopper 6 under the shell 4 for collection and treatment under the action of the rapping device. The flue gas further treated by the fixed electrode 3 then leaves and is output through the outlet horn 5.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
