[0068] like Figure 1 As shown, an embodiment of the present invention provides an electrostatic precipitator, including a housing 1, a dust removal mechanism 3 and a discharge mechanism 2. The housing 1 has an internal cavity and a discharge port connected to the internal cavity and used to discharge dust; the dust removal mechanism 3 is located in the internal cavity; the discharge mechanism 2 includes a discharge hopper 201, a crushing and cleaning device arranged in the discharge hopper 201, and a sealing door 202 capable of opening and closing the outlet of the discharge hopper 201, and the inlet of the discharge hopper 201 is connected to the discharge port;

[0069] The crushing and cleaning device includes: a crushing component located in the discharge hopper 201 and used to crush the dust in the discharge hopper 201; and a driving component used to drive the crushing component to move in the discharge hopper 201.

[0070] In the electrostatic precipitator provided by the embodiment of the present invention, when the dust generated by the electrostatic precipitator during operation (including the cake-shaped dust generated by the dust removal mechanism 3) falls into the discharge hopper 201 of the discharge mechanism 2, the sealing door 202 maintains the state of opening the outlet of the discharge hopper 201, and the driving component of the crushing and cleaning device drives the crushing component to move in the discharge hopper 201, so that the crushing component contacts the dust in the discharge hopper 201 and crushes the dust, so that the dust can be discharged through the outlet of the discharge hopper 201. Through the above arrangement, the situation of blockage caused by the inability to discharge dust is effectively avoided, and the stable operation of the electrostatic precipitator is ensured.

[0071] In this embodiment, the crushing assembly includes a crushing rod 206 and a spiral plate 207. The crushing rod 206 includes a first rod and a second rod.

When the driving assembly drives the first rod to rotate, the second rod rotates along the first rod to crush the dust; the second rod drives the spiral plate 207 to rotate, cleans the inner wall of the discharge hopper 201, and hangs off the dust attached to or falling on the inner wall of the discharge hopper 201, and discharges it from the outlet of the discharge hopper 201.

[0072] In the embodiment of the present invention, the axis of the spiral plate 207 coincides with the extension direction of the first rod.

[0073] The spiral plate 207 cooperates with the inner wall of the discharge hopper 201 , so that the spiral plate 207 contacts the inner wall of the discharge hopper 201 , or the spiral plate 207 cooperates with the inner wall of the discharge hopper 201 with a gap.

[0074] In this embodiment, the driving assembly includes a protective shell 205, a first transmission structure and a first driving component 208. The protective shell 205 is fixed in the discharge hopper 201, and one end of the first rod extends into the protective shell 205; the first transmission structure is located in the protective shell 205 and its output end is connected to the first rod. The protective shell 205 can prevent dust from contacting the first transmission structure. Preferably, the protective shell 205 has an inclined top surface on the side facing the inlet of the discharge hopper 201, so as to guide the dust to flow to the outlet of the discharge hopper 201 under the action of gravity.

[0075] The driving end of the first driving component 208 is connected to the input end of the first transmission structure. The first transmission structure includes a first bevel gear 210 and a second bevel gear 211 that are meshed with each other.

[0076] The output end of the first transmission structure is the second bevel gear 211, and the center of the second bevel gear 211 is connected to the first rod. When the first driving component 208 drives the first bevel gear 210 to rotate through the rotating shaft 209, the second bevel gear 211 rotates and drives the first rod to rotate.

[0077] Of course, the driving assembly may also be configured as other structures, such as directly configuring a motor, with the driving end of the motor being connected to the first rod.

[0078] The electrostatic precipitator in this embodiment further includes a sealing door driving device for controlling the sealing door 202 to open and close the outlet of the discharge hopper 201.

[0079] In some embodiments, the sealing door driving device includes a swing frame 203 and a dust exhaust cylinder 204. The sealing door 202 is hinged to the outlet of the discharge hopper 201, one end of the swing frame 203 is connected to the sealing door 202, the main body of the dust exhaust cylinder 204 is fixedly connected to the outer wall of the discharge hopper 201, and the driving end of the dust exhaust cylinder 204 is connected to the other end of the swing frame 203. Through the drive of the dust exhaust cylinder 204, the swing frame 203 can drive the sealing door 202 to rotate relative to the outlet of the discharge hopper 201, thereby realizing the operation of opening and closing the outlet of the discharge hopper 201.

[0080] Of course, the sealing door driving device can also be set to other structures, such as a rotating motor that directly drives the sealing door 202 to rotate relative to the outlet of the discharge hopper 201, etc., which is not specifically limited here and is within the protection scope.

[0081] Specifically, a discharge hopper 201 is fixedly connected to the bottom of the casing 1, a sealing door 202 is abutted against the bottom of the discharge hopper 201, a swing frame 203 is connected to one side of the sealing door 202, the swing frame 203 is rotatably connected to one side of the discharge hopper 201 through a bracket, and a dust exhaust cylinder 204 is rotatably connected to one side of the discharge hopper 201 through a bracket, a protective shell 205 is connected to the inner wall of the discharge hopper 201 through a bracket, a crushing rod 206 is rotatably penetrated below the inner wall of the protective shell 205, and the crushing rod 206 is rotatably connected to the discharge hopper 201 through a bracket. 01, and the outer side of the crushing rod 206 is connected with a spiral plate 207, the spiral plate 207 abuts against the inner wall of the discharge hopper 201, one side of the discharge hopper 201 is connected with a first driving component 208 through a support, the output end of the first driving component 208 is connected with a rotating shaft 209, the rotating shaft 209 penetrates and rotates in the discharge hopper 201 and the protective shell 205, the outer side of the rotating shaft 209 inside the protective shell 205 is connected with a first bevel gear 210, the lower part of the first bevel gear 210 is meshed with a second bevel gear 211, and the second bevel gear 211 is connected to the top of the crushing rod 206.

[0082] During the process of opening and closing the sealing door 202, the dust exhaust cylinder 204 is shortened to pull the swing frame 203 to drive the sealing door 202 to rotate and open, and then the first driving component 208 is started to drive the rotating shaft 209 to rotate in the protective shell 205, and the rotating shaft 209 drives the first bevel gear 210 to drive the second bevel gear 211 to rotate, and the second bevel gear 211 drives the crushing rod 206 to rotate to crush the dust blocks. At the same time, the crushing rod 206 drives the spiral plate 207 to clean the inner wall of the discharge hopper 201, scrape off the smoke and discharge it, so as to prevent the electrostatic precipitator from being blocked by smoke and dust.

[0083] After research, it was found that the fixed-spacing corona electrode group and dust collecting electrode group in the electrostatic precipitator remove dust from the flue gas, and the electric field strength is adjusted only by adjusting the voltage, so that the adjustment range of the electric field strength is limited. As a result, the higher the concentration of the flue gas, the worse the ionization effect and the lower the charge of the particulate matter, which affects the dust removal effect.

[0084] In order to facilitate the adjustment of the electric field strength, in the electrostatic precipitator provided in the embodiment of the present invention, the dust removal mechanism 3 includes an anode component 306, a cathode component 307 and a spacing adjustment component, wherein the cathode component 307 is arranged corresponding to the anode component 306; the spacing adjustment component is used to adjust the spacing between the anode component 306 and the cathode component 307.

It can be understood that the scissor frame 308 can include a plurality of cross-connected connecting rod groups, and the cross-connected part of each connecting rod group is connected to the support frame. In the process where the linear drive component 309 is used to drive the extension and retraction of the scissor-type frame 308 and / or the change of the distance between two adjacent support frames, the distance between the cross-connected parts of the two adjacent groups of connecting rods changes, so that the distance between the two adjacent support frames changes, and then the distance between the anode component 306 supported by one support frame and the cathode component 307 supported by another support frame changes.

[0086] In this embodiment, the guide structure includes a slide bar 301, the extension direction of the slide bar 301 is the same as the arrangement direction of the multiple support frames, and the multiple support frames have a sliding portion (through hole) that slides with the slide bar 301.

[0089] An air bag 305 is provided on one side of the driving frame 304 facing the inner wall of the housing 1 , and the air bag 305 is used to fill the gap between the driving frame 304 and the inner wall of the housing 1 .

[0090] Specifically, the airbag 305 is extended and retracted to fill the gap between the driving frame 304 and the inner wall of the housing 1, thereby avoiding collision between the driving frame 304 and the housing 1 and improving the safety of use.

[0091] The airbag 305 can always remain in an inflated state, and the airbag 305 can be deformed to satisfy the effect of filling the gap between the driving frame 304 and the inner wall of the housing 1.

[0092] The airbag 305 can also be maintained in an inflated and deflated state so as to be inflated and deflated as the driving frame 304 approaches or moves away from the inner wall of the housing 1 .

The gas generated by the air pump 408 enters the gas collection bag 407, and the gas in the gas collection bag 407 passes through the gas distribution pipe 406 and enters multiple air inlet pipes 404 when the solenoid valve 405 is opened. The multiple air inlet pipes 404 all have a blowing pipe 403 connected thereto, and the blowing pipe 403 has an air jet port for jetting air to the filter 401 and the electric heating network 402.

[0106] Specifically, a filter screen 401 is connected to the inner wall near the inlet (port) of the casing 1 through a bracket, and an electric heating network 402 is connected to the inner wall of the casing 1 near the filter screen 401 through a bracket. A blow pipe 403 is provided on one side of the filter screen 401 and the electric heating network 402. The blow pipe 403 penetrates the casing 1 and is connected to an air intake pipe 404 located outside the casing 1. The air intake pipe 404 is connected to the front part of the casing 1 (near the inlet of the casing 1), and a solenoid valve 405 is connected to one side of the air intake pipe 404, and an air distribution pipe 406 is connected to one side of the solenoid valve 405. The other end of the air distribution pipe 406 is connected to an air collecting bag 407, and the air collecting bag 407 is connected to the upper surface of the casing 1, and an air pump 408 is connected to one side of the air collecting bag 407, and the air pump 408 is connected to the top surface (upper surface) of the casing 1.

[0107] like Figure 8 As shown, the switch structure includes a stop bar 409, a seal bar 410, a connecting rod 411, a circular gear 412, a tooth plate 413 and a door opening cylinder 414. The door opening cylinder 414 controls the tooth plate 413 to move along its extension direction, drives the circular gear 412 to rotate, and causes the connecting rod 411 to rotate, thereby driving the seal bar 410 to rotate, so that the gap between the seal bar 410 and the stop bar 409 changes.

[0108] Specifically, a baffle 409 is connected to the inner wall of the first outlet (throughout) below the casing 1, a seal 410 is provided on one side of the baffle 409, a connecting rod 411 is connected through the seal 410, the connecting rod 411 is rotated on the inner wall of the casing 1, the connecting rod 411 is connected to a circular gear 412, the circular gear 412 is meshed with a tooth plate 413, the tooth plate 413 is slidably connected to the casing 1 (close to the inlet of the casing 1) through a bracket, and a door opening cylinder 414 is connected to one side of the tooth plate 413, and the door opening cylinder 414 is connected to the front of the casing 1 through a bracket.

[0109] In addition, a humidity sensor 415 is connected to the inner wall of the inlet of the housing 1 through a bracket. The humidity sensor 415 can be connected to the electric heating network 402 in communication, so as to perform corresponding processing on the electric heating network 402 according to the humidity detection result. The humidity sensor 415 can also be connected to the drive device (door opening cylinder 414) of the switch structure and the starter device (air pump 408 and solenoid valve 405) of the dust blowing component in communication, so as to perform corresponding processing according to the humidity detection result.

[0110] Specifically, the humidity sensor 415 detects the humidity. If the humidity reaches the set threshold, the electric heating network 402 is energized, the air is filtered through the filter 401, and then filtered again while being heated by the electric heating network 402. The door opening cylinder 414 is started regularly to push the tooth plate 413 to slide, and the tooth plate 413 drives the circular gear 412 to drive the connecting rod 411 to rotate, and the connecting rod 411 drives the seal 410 to rotate and open, connecting the casing 1 with the discharge hopper 201 (the first discharge hopper) to allow dust (smoke) to fall into the discharge hopper 201. At the same time, the air pump 408 is started to inflate the air collecting bag 407, and then the solenoid valve 405 is opened to eject the air in the air collecting bag 407 from the air distribution pipe 406 through the air inlet pipe 404 into the blowing pipe 403, and the filter 401 and the electric heating network 402 are blown to remove dust. Filtration, dehumidification and self-cleaning are used to allow the electrostatic precipitator to pre-treat the air.

[0111] In summary, when using the electrostatic precipitator provided by the embodiment of the present invention, the dust-containing air supply duct is connected to one end (inlet) of the casing 1 having the humidity sensor 415, and the exhaust duct is connected to the other end of the casing 1. The body (dust-containing air) is coarsely filtered through the filter 401, and then passes through the gap between the fixed frame 302, the linkage frame 303 and the driving frame 304. The smoke particles are given a negative charge by the cathode component 307 and adsorbed by the anode component 306. The air after dust removal is then discharged.

[0112] If the humidity sensor 415 detects that the humidity in the dusty air is high, the electric heating network 402 is controlled to be energized to heat and dry the passing dusty air. After a predetermined time, the door opening cylinder 414 is started to open the multiple sets of seals 410, and the air pump 408 is started to inflate and pressurize the air collecting bag 407. The solenoid valve 405 is opened to blow compressed air onto the filter 401 and the electric heating network 402, and the dust falls into the discharge hopper 201. The second driving component 317 (dust removal motor) can also be started to drive the outer flower rod 316 to rotate, and the outer flower rod 316 drives the fourth bevel gear 315 to drive the third bevel gear 314 to rotate, and the third bevel gear 314 drives the shaft 311 to rotate, and drives the pendulum 312 to rotate upward. The weight of the pendulum 312 swings the pendulum 312 down, and strikes the hammer plate 313 to drive the anode component 306 and the cathode component 307 to vibrate, shake off the adsorbed dust, and drop it into the discharge hopper 201, then start the dust exhaust cylinder 204 to open the sealing door 202, and start the first driving component 208 to break the accumulated dust and push it downward, scrape the dust from the inner wall of the discharge hopper 201, discharge it into the dust container, and then dump it.
