[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an embodiment of the present invention provides an air purification fanless radial flow electrostatic precipitator, comprising an annular shell 1, a driving mechanism 6, an electrostatic precipitator mechanism 7 and a movable plate 8. The side and top of the annular shell 1 are respectively provided with an air inlet and an air outlet. The electrostatic precipitator mechanism 7 comprises a discharge net 71, a dust collecting electrode mesh plate 72 and a guide plate 73. The dust collecting electrode mesh plate 72 is set as a regular quadrangular prism structure with openings at both ends. Four discharge nets 71 are respectively arranged on the outside of the dust collecting electrode mesh plate 72, and a guide plate 73 is connected between two adjacent discharge nets 71. The four discharge nets 71 are respectively parallel to the corresponding side surfaces of the dust collecting electrode mesh plate 72. A movable plate 8 is provided between the four discharge nets 71 and the corresponding side surfaces of the dust collecting electrode mesh plate 72. Hard bristles 81 are provided on both sides of the movable plate 8. The driving mechanism 6 is used to drive the movable plate 8 to move back and forth so that the hard bristles 81 are inserted into the mesh holes of the discharge net 71 or the dust collecting electrode mesh plate 72, and the air outlet is connected to the top opening of the dust collecting electrode mesh plate 72.

[0030] Specifically, the dust collecting electrode mesh plate 72 can also be a regular pentagonal prism structure with openings at both ends. The corresponding discharge meshes 71 are set to five, and the movable plates 8 are also set to five. It can also be a regular hexagonal prism structure with openings at both ends. That is to say, the number of sides of the dust collecting electrode mesh plate 72 is the same as the number of the discharge meshes 71 and the movable plates 8.

[0031] In this embodiment, a high-voltage DC power supply (not shown in the figure) is provided on the housing 1. A potential difference is generated between the discharge grid 71 and the dust collecting electrode mesh plate 72 through the electrical connection with the high-voltage DC power supply. The potential difference can be 10,000 to 40,000 volts. After the air enters the housing 1 through the air inlet, the air is distributed toward the four discharge grids 71 ​​under the action of the guide plate 73. The air approaches and passes through the discharge grid 71. In the process of approaching and passing, the larger flying dust in the air is blocked, and the dust particles in the air are charged due to the electric field of the discharge grid 71. The air mixed with the charged dust particles approaches and passes through the dust collecting grid 71. On the surrounding surfaces of the electrode mesh plate 72, the charged dust particles will be electrically adsorbed and intercepted by the dust collecting electrode mesh plate 72 in the process of approaching and passing through the dust collecting electrode mesh plate 72, and the dust-removed air will be discharged from the air outlet through the top opening of the dust collecting electrode mesh plate 72. The moving plate 8 is regularly driven to reciprocate by the driving mechanism 6, so that the hard bristles 81 are inserted into the mesh holes of the discharge mesh 71 or the dust collecting electrode mesh plate 72, thereby knocking out the larger flying dust blocking the discharge mesh 71 and the dust particles on the dust collecting electrode mesh plate 72 from the mesh holes, thereby achieving all-round and dead-angle cleaning of the discharge mesh 71 and the dust collecting electrode mesh plate 72, thereby improving the cleaning effect and efficiency.

[0032] It should be noted that the air outlet can be connected to the gas processing equipment through a pipeline, so that the device can be used as a pre-dust removal device for the subsequent gas processing equipment, so that air can enter from the air inlet and be discharged from the air outlet.

[0033] Optionally, combined Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the driving mechanism 6 includes a fan blade 61, a slip ring 62, a permanent magnet block 63 and an annular frame 64. The annular frame 64 is connected to the housing 1 and is arranged on the outer side of the discharge grid 71. The slip ring 62 is rotatably sleeved on the annular frame 64. The slip ring 62 is composed of two magnetic semicircular rings connected end to end and having opposite magnetic properties. A plurality of fan blades 61 are connected to the slip ring 62 along the circumferential direction. The permanent magnet block 63 is connected to the moving plate 8.

[0034] In this embodiment, the annular frame 64 serves to install the fan blades 61 and the slip rings 62, and the annular frame 64 will not affect the air entering the discharge net 71 and the dust collecting electrode mesh plate 72. Since the slip ring 62 is composed of two magnetic semicircular rings connected end to end and with opposite magnetic properties, when the fan blades 61 are driven by the airflow to rotate, the slip rings 62 are driven to rotate synchronously, thereby generating periodically changing attractive and repulsive forces on the permanent magnet block 63, thereby driving the movable plate 8 to reciprocate toward the center of the shell 1 or away from the center of the shell 1. Since the discharge net 71 and the dust collecting electrode mesh plate 72 are respectively arranged on both sides of the movable plate 8, when the movable plate 8 reciprocates, the movable plate 8 can intermittently approach the discharge net 71 and the dust collecting electrode mesh plate 72, so that the hard bristles 81 on the corresponding sides of the movable plate 8 can be inserted into the mesh holes of the discharge net 71 and the dust collecting electrode mesh plate 72, so as to achieve the tamping of the dust and scale blocked in the mesh holes.

[0035] Furthermore, combined with Figure 1 , Figure 3 and Figure 5 As shown, the air purification fanless radial flow electrostatic precipitator device also includes an air guide plate 2 and an adjustment mechanism 3. The air inlet is arranged in a ring shape, and multiple air guide plates 2 are arranged in a ring inside the air inlet. An air inlet channel is formed between two adjacent air guide plates 2. The adjustment mechanism 3 is used to drive the multiple air guide plates 2 to rotate synchronously to change the direction of the air inlet channel.

[0036] In this optional embodiment, if Figure 3 As shown, the direction of the arrow is the direction of the airflow. When it is necessary to clean the dust scale on the discharge net 71 and the dust collecting electrode mesh plate 72, the air guide plate 2 is adjusted to a direction deviating from the radial direction of the slip ring 62 through the adjustment mechanism 3. At this time, the air guide plate 2 is recorded as the first position, so that the direction of the air inlet channel is toward the direction of the fan blade 61, and then the fan blade 61 is applied with thrust to drive the slip ring 62 to rotate, so as to realize the dredging operation of the dust scale in the mesh of the discharge net 71 and the dust collecting electrode mesh plate 72. A part of the dust scale falls to the bottom of the shell 1 for subsequent cleaning, and the other part of the dust scale moves with the air flow to the top opening of the dust collecting electrode mesh plate 72, and is finally discharged from the air outlet of the shell 1; Figure 5As shown, the direction of the arrow is the direction of the airflow. When the dust removal operation is performed, the air guide plate 2 is adjusted to the radial direction close to the slip ring 62 through the adjustment mechanism 3. At this time, the air guide plate 2 is recorded as the second position, so that the direction of the air inlet channel is not toward the fan blade 61, so that the airflow does not blow toward the fan blade 61, but directly blows toward the annular frame 64 to enter the area of ​​the discharge grid 71 and the dust collecting electrode grid plate 72 to perform the electric dust removal operation.

[0037] Furthermore, combined with Figure 4 As shown, an annular track groove 641 is provided on the outer circumferential surface of the annular frame 64 , and the slip ring 62 is rotatably sleeved in the annular track groove 641 .

[0038] In this optional embodiment, the annular track groove 641 can be fixed to the annular frame 64 by screw connection, or by welding, so that the slip ring 62 can perform circular rotation along the annular track groove 641 driven by the fan blades 61.

[0039] In other optional embodiments, in order to reduce the resistance of the slip ring 62 during rotation, the annular track groove 641 can be replaced by a bearing. Specifically, the inner ring of the bearing is mounted on the outer circumferential surface of the annular frame 64, and the outer ring of the bearing is fixedly connected to the inner ring of the slip ring 62. The outer ring of the slip ring 62 is used to connect with the fan blade 61. In this way, the rotation of the slip ring 62 relative to the annular frame 64 can also be achieved, and the resistance of the slip ring 62 during rotation can be effectively reduced.

[0040] Furthermore, combined with Figure 3 As shown, the fan blade 61 is configured as an arc-shaped structure, and the arc surface of the fan blade 61 that is concave inward is configured as the windward side.

[0041] In this optional embodiment, the fan blade 61 is integrally formed into an arc-shaped structure, so that the airflow after passing through the air inlet channel can act on the windward side of the fan blade 61, and the windward side of the fan blade 61 is an arc surface that is concave inward, thereby increasing the thrust applied by the airflow to the windward side of the fan blade 61, allowing the fan blade 61 to rotate stably, thereby driving the slip ring 62 to rotate stably.

[0042] Optionally, combined Figure 1 and Figure 2 As shown, the adjustment mechanism 3 includes a swivel 31, a connecting rod 32, a swing arm 33 and a rotating rod 34. The swivel 31 is rotatably connected to the upper surface of the shell 1, and multiple connecting rods 32 are arranged on the swivel 31. One end of the connecting rod 32 is rotatably connected to the swivel 31 through a rotating shaft, and the other end of the connecting rod 32 is rotatably connected to one end of the swing arm 33 through a rotating shaft. The other end of the swing arm 33 is fixedly connected to the rotating rod 34, and the other end of the rotating rod 34 extends downward and is rotatably connected to the inner bottom surface of the shell 1. The air guide plate 2 is sleeved on the corresponding rotating rod 34.

[0043] In this optional embodiment, the upper surface of the shell 1 can be provided with an annular groove, and the swivel 31 is rotatably connected to the annular groove, or a bearing can be installed on the upper surface of the shell 1, and the swivel 31 is installed in the inner ring of the bearing. The above two methods can realize the rotation of the swivel 31 relative to the shell 1. By rotating the swivel 31 clockwise or counterclockwise, the connecting rod 32 pulls the rotating rod 34 to rotate through the swing arm 33, thereby realizing the synchronous rotation adjustment of multiple air guide plates 2, and then changing the direction of the air inlet channel.

[0044] Furthermore, combined with Figure 1 and Figure 2 As shown, the adjustment mechanism 3 further includes a rocker 35 , one end of which is connected to the rotating ring 31 , and the other end of which extends in a direction away from the center of the rotating ring 31 .

[0045] In this optional embodiment, one end of the rocker arm 35 can be threadedly connected to the swivel 31, and the rocker arm 35 can also be integrally formed with the swivel 31. The other end of the rocker arm 35 extends away from the center of the swivel 31 to facilitate manual adjustment through the rocker arm 35. By driving the swivel 31 to rotate back and forth, the multiple connecting rods 32 can be driven to move, thereby realizing the rotation of the air guide plate 2.

[0046] Furthermore, combined with Figure 6 As shown, the movable plate 8 is provided with a plurality of inclined holes 82 , and the extending direction of the inclined holes 82 is inclined to the extending direction of the hard bristles 81 .

[0047] In this optional embodiment, if Figure 6 As shown, the arrow in the figure indicates the direction of gas flow. When the hard bristles 81 on one side of the movable plate 8 are inserted into the mesh holes on the dust collecting electrode mesh plate 72, the airflow passes through the inclined holes 82 and blows toward the hard bristles 81 at the corresponding positions, thereby driving the hard bristles 81 to vibrate slightly to a certain extent. That is to say, the hard bristles 81 are able to vibrate slightly in the mesh holes of the dust collecting electrode mesh plate 72, so that the hard bristles 81 can more easily clear the dust and dirt stuck in the mesh holes, thereby improving the effect of clearing the dust and dirt in the mesh holes of the dust collecting electrode mesh plate 72.

[0048] Furthermore, combined with Figure 2 and Figure 3 As shown, the air purification fanless radial flow electrostatic precipitator device also includes a slide rod 9, and the two opposite movable plates 8 are slidably connected to the slide rod 9. The two ends of the slide rod 9 pass through the corresponding side surfaces of the dust collecting electrode mesh plate 72 and the corresponding discharge mesh 71 and are then connected to the annular frame 64.

[0049] In this optional embodiment, both ends of the slide rod 9 can be welded to the annular frame 64, thereby improving the overall structural strength of the annular frame 64. Figure 3As shown, there are four slide bars 9 in total, which are grouped in pairs. The two slide bars 9 in one group pass through two opposite moving plates 8 in one group, and the two slide bars 9 in another group pass through two opposite moving plates 8 in another group, and the two groups of slide bars 9 are staggered up and down, that is, staggered along the Z-axis direction. The moving plates 8 are provided with sliding holes for the slide bars 9 to pass through and slide in. In this way, the slide bars 9 achieve a guiding effect when reciprocating on the moving plates 8. At the same time, the slide bars 9 also cross the discharge grid 71 and the dust collecting electrode grid plate 72, thereby supporting the discharge grid 71 and the dust collecting electrode grid plate 72 to a certain extent, thereby improving the stability of the discharge grid 71 and the dust collecting electrode grid plate 72.

[0050] Furthermore, combined with Figure 1 and Figure 2 As shown, the air purification fanless radial flow electrostatic precipitator device also includes an air outlet pipe 4, and the air outlet pipe 4 is connected to the air outlet.

[0051] In this optional embodiment, since the dust collecting electrode mesh plate 72 is set to a regular quadrangular prism structure with openings at both ends, in other words, the top opening and the bottom opening of the dust collecting electrode mesh plate 72 are both rectangular, and the air outlet is connected to the top opening of the dust collecting electrode mesh plate 72. The air outlet can be circular. In order to facilitate the connection with the air outlet pipe 4, and the area of ​​the air outlet is smaller than the top opening area of ​​the dust collecting electrode mesh plate 72, the gas after dust removal by the dust collecting electrode mesh plate 72 can only enter the air outlet pipe 4 through the top opening of the dust collecting electrode mesh plate 72 through the air outlet. It should be noted that an air induced draft device can be installed on the air outlet pipe 4 to allow air to enter the shell 1 from the air inlet and then be discharged into the air outlet pipe 4 through the air outlet. The air outlet pipe 4 can also be connected to the gas processing equipment, so that the device can be used as a pre-dust removal device of the subsequent gas processing equipment, so that it can be flexibly used according to the actual application scenario.

[0052] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
