Description

Technical Field

[0001] This invention relates to the field of VOCs purification and treatment equipment, and more specifically, to a VOCs gas purification and reuse device. Background Technology

[0002] Environmental protection and energy conservation and emission reduction are key tasks for the present and for a long time to come, and environmental protection and pollution control for industrial enterprises are of paramount importance. In the process of industrial production and fuel combustion, particulate matter and various volatile organic compounds (VOCs) are inevitably generated. For example, in the process of high-temperature heating and organic solvent cooling, a large amount of waste gas containing high-temperature particulate matter and VOCs will be generated. If the high-temperature waste gas is not purified, it will cause serious pollution to the environment and even endanger human health.

[0003] The purification of VOCs waste gas containing dust requires pretreatment to remove dust and particulate matter from the waste gas before further removal of VOCs pollutants. Currently, methods for removing dust and particulate matter include dry dust removal and wet dust removal, while methods for removing VOCs pollutants include adsorption, biological methods, and incineration.

[0004] Electrostatic plasma treatment equipment is a device that uses electrostatic purification to collect dust from VOCs. It is an ideal device for purifying industrial waste gas. Its purification work is mainly accomplished by two systems: the discharge electrode and the precipitation electrode. When a high-voltage direct current is input between the two electrodes, anions and cations are generated in the electrode space and act on the surface of the waste gas particles passing through the electrostatic field. Under the action of the electric field force, they move towards the electrode with the opposite polarity and are deposited on the electrode, thus achieving the purpose of dust collection.

[0005] Existing electrostatic plasma treatment equipment has a rapping device installed inside. The rapping device can periodically tap the electrode plates to make them vibrate, shaking off the dust adhering to the electrode plates and letting it fall into the lower ash hopper. However, the dust removal effect is poor, and a lot of dust will still remain on the electrode plates. This residual dust will cover the electrode plates and affect the effect of subsequent electrostatic dust removal. Moreover, the dust that is shaken off will be raised again during the falling process and merge into the airflow, resulting in poor dust removal effect. Therefore, there is an urgent need to design a VOCs gas purification and reuse device. Summary of the Invention

[0006] 1. Technical problems to be solved

[0007] The existing electrostatic plasma treatment equipment has a built-in rapping device that periodically taps the electrode plates to vibrate them, dislodging dust adhering to the plates and causing it to fall into the lower ash hopper. However, the dust removal effect is poor, and a large amount of dust remains on the electrode plates. This residual dust covers the electrode plates, affecting the subsequent electrostatic dust removal effect. Moreover, the dislodged dust is re-raised during its fall and merges into the airflow, resulting in poor dust removal efficiency. The purpose of this invention is to provide a VOCs gas purification and reuse device that can effectively solve the problems mentioned in the background technology.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of this invention are:

[0019] ① The electrostatic treatment structure enables the VOCs gas purification and reuse device to collect dust from waste gas. A centrifugal de-asher drives the electrostatic treatment structure, which in turn drives a vibrating de-asher in reciprocating motion. This vibrating de-asher strikes the electrostatic collection plate and electrostatic discharge plate, dislodging the collected dust. A dust collection mechanism gathers the dislodged dust for cleaning. An active de-ashing component cleans the electrostatic collection plate, removing residual dust and improving the dust removal efficiency. The centrifugal de-asher rotates the electrostatic treatment structure, which in turn rotates the conductive terminals, de-energizing the electrostatic collection plate and electrostatic discharge plate at the bottom of the structure. This eliminates the dust adsorption force of the electrostatic collection plate, further enhancing the dust removal efficiency and improving the practicality of the electrostatic plasma treatment device.

[0020] ② The electrostatic treatment structure is driven by the centrifugal dust collector, which allows the electrostatic collection plate to rotate downwards around the insulating hollow cylinder. The rotating electrostatic collection plate can align the dust with the dust collection holes, so that the detached dust falls into the dust treatment mechanism. The electrostatic collection plate and electrostatic discharge plate can separate the dust collection holes from the internal cavity of the electrostatic treatment column, preventing the detached dust from being re-raised and flowing into the airflow, which would lead to poor dust removal efficiency. This improves the practicality of the VOCs gas purification and reuse device. Attached Figure Description

[0043] Working principle:

[0044] First, the dust-laden VOCs waste gas enters the corresponding electrostatic treatment column 22 through the waste gas inlet pipe 15 and its corresponding fan-shaped gas delivery pipe 23. Then, the waste gas flows from right to left in the fan-shaped chamber at the top of the electrostatic treatment column 22. Next, the isosceles discharge tip 27 discharges and charges the dust in the waste gas. Afterward, the waste gas enters the electrostatic treatment column 22 at the left end of the dust treatment block 11 through the fan-shaped constant-flow pipe 21 and flows to the left in the fan-shaped chamber at its top. Then, the charged dust is adsorbed on the surface of the electrostatic collection plate 24 under the action of the electric field, achieving the effect of dust removal and turning the waste gas into clean gas. Then, the clean gas is discharged through the corresponding fan-shaped gas delivery pipe 23 and the clean gas discharge pipe 16 and enters the VOCs purification treatment equipment for purification and reuse. After that, it is distributed through the... The electric controller 17 turns on the power motor 309, which then drives the drive bevel gear 310 to rotate. The drive bevel gear 310, through its meshing with the bevel gear grooved disc 307, drives the transmission vertical shaft 304 to rotate. The transmission vertical shaft 304, through the meshing of the intermediate bevel gear 305 and the transmission bevel gear 303, drives the transmission short shaft 302 to rotate. The transmission short shaft 302 then drives the insulating hollow cylinder 28 to rotate. The insulating hollow cylinder 28 then drives the electrostatic collection plate 24 and the electrostatic discharge electrode plate 25 to rotate. The electrostatic collection plate 24, carrying the dust adhering to its surface, moves synchronously. The end of the electrostatic collection plate 24 gradually changes from an upward tilt to a downward tilt. Then, the active ash removal gravity block 43, under the action of gravity, moves along the main... The surface of the active dust removal slide bar 42 slides downwards, and then the active dust removal gravity block 43 slides on the surface of the active dust removal hard brush 46 along with it. The active dust removal hard brush 46 then pushes the dust adhering to the surface of the electrostatic collection plate 24 upwards to its free end. During this process, the insulating hollow cylinder 28 rotates with the insulating attachment block 63. Then, the insulating attachment block 63 rotates with the conductive contact rod 68 through the conductive buffer plug 67. Then, the conductive buffer plug 67 applies pressure to the conductive contact rod 68 under the elastic force of the pre-compression elastic element 66. Then, the end of the conductive contact rod 68 abuts against the left side of the conductive ring 691. Then, the end of the conductive contact rod 68 slides into the interior of the separation inclined hole 692. Afterwards, the conductive buffer plug 67, under the elastic force of the pre-compression elastic element 66... Under the action of force, the conductive contact rod 68 moves to the right relative to the insulating attachment block 63. Then, the conductive contact rod 68 separates from the conductive ring 691. Next, the electrostatic collection plate 24 and electrostatic discharge plate 25 corresponding to the conductive contact rod 68 are de-energized. After that, the attraction of the electrostatic collection plate 24 to the dust disappears, and the dust falls off the surface of the electrostatic collection plate 24. Then, the electrostatic collection plate 24 applies a pushing force to the striking mallet 56. Then, the striking mallet 56 rotates around the self-rotating linkage rod 54 as the central axis and rotates synchronously with the deflection lever 53. Then, the deflection lever 53 pulls the stress traction spring 52. Then, the stress traction spring 52 stretches elastically, and the elastic potential energy increases. Then, the striking mallet 56 passes over the end of the electrostatic collection plate 24, so that the striking mallet 56 is released.Then, under the elastic tension of the stress traction spring 52, the deflection arm 53 rotates in the opposite direction via the self-transforming linkage rod 54, causing the striking mallet 56 to strike the subsequent electrostatic discharge plate 25. The electrostatic discharge plate 25 then applies a pushing force to the striking mallet 56. Following the same principle, the striking mallet 56 slips off the end of the electrostatic discharge plate 25 and strikes the active dust removal gravity block 43 outside the subsequent electrostatic collection plate 24, thus causing the electrostatic collection plate 24 and the electrostatic discharge plate 25 to vibrate. This causes the dust on the electrostatic collection plate 24 to fall off. Then, the active dust removal rod 41 enters the positioning opening slot 44 and presses against its inner wall. At this time, the active dust removal gravity block 43 moves to the extreme position outside the active dust removal slide rod 42. At this time, the active dust removal gravity block 43 slides and connects with the inner wall of the electrostatic treatment column cylinder 22. After that, the fallen dust falls into the inside of the dust collection hopper 14 through the dust collection hole 29. Then, the insulating hollow cylinder 28 continues to rotate with the electrostatic collection plate 24 and the electrostatic discharge electrode plate 25. Then the electrostatic collection plate 24... The end of the electrostatic discharge plate 25 gradually changes from an downward tilt to an upward tilt. Then, under the influence of gravity, the active ash removal gravity block 43 slides along the surface of the active ash removal slide rod 42 and approaches the insulating hollow cylinder 28 until it rests against the surface of the insulating hollow cylinder 28, thus resetting the active ash removal gravity block 43. Simultaneously, the conductive contact rod 68 slides from the inner wall of the separation inclined hole 692 to the left side of the conductive ring 691. Then, the inclined surface of the separation inclined hole 692 faces the conductive contact rod 68. A leftward thrust is applied, causing the conductive contact rod 68 to move to the left. The conductive contact rod 68 then moves the conductive buffer plug 67 to the left, which in turn compresses the pre-compression elastic element 66. The pre-compression elastic element 66 then undergoes elastic compression, increasing its elastic potential energy. Subsequently, the corresponding electrostatic collection plate 24 and electrostatic discharge plate 25 are energized. The fan-shaped chamber formed by the energized electrostatic collection plate 24 and electrostatic discharge plate 25 aligns with the fan-shaped gas delivery pipe 23. The exhaust gas then flows within the fan-shaped chamber. This process is repeated.
