Detailed Implementation

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figures 1 to 3 As shown, Embodiment 1 provides a corona-charged spray device, including a spray support 1, pure water pressure nozzles 2, and high-voltage electrode needles 3. Multiple pure water pressure nozzles 2 are arranged on the spray support 1. A ring of high-voltage electrode needles 3 is arranged on the front side of each pure water pressure nozzle 2. The water mist sprayed from the pure water pressure nozzles 2 passes through the annular area formed by the high-voltage electrode needles 3. A corona discharge region is formed between the high-voltage electrode needles 3 and the pure water pressure nozzles 2. The large amount of plasma generated by the corona discharge not only efficiently charges the spray, but the active particles in the plasma can also effectively treat harmful gases. The efficiently charged spray also has a good treatment effect on fine particulate matter.

[0017] Optionally, an insulating bracket 4 is also included, which is mounted on the spray bracket 1, and the high-voltage electrode needles 3 are mounted on the insulating bracket 4. The insulating bracket 4 is grounded. Specifically, a conductive ring 5 is provided on the insulating bracket 4 corresponding to each ring of high-voltage electrode needles 3, and the high-voltage electrode needles 3 are fixedly mounted on the conductive ring 5. The conductive ring 5 can be integrally formed with the high-voltage electrode needles 3, and the conductive ring 5 can be made of copper. An external high-voltage cable can be directly electrically connected to the conductive ring 5, simultaneously supplying power to the multiple high-voltage electrode needles 3 on the conductive ring 5.

[0018] Optionally, the insulating bracket 4 includes a fixed part 401 and a movable part 402. The fixed part 401 is mounted on the spray bracket 1, and the movable part 402 is mounted on the fixed part 401. The movable part 402 can adjust the position fixed on the fixed part 401 to adjust the distance between the pure water pressure nozzle 2 and the high-pressure electrode needle 3.

[0019] The fixed part 401 has multiple positioning holes 403 evenly spaced, and the movable part 402 has positioning screws 404. By connecting the positioning screws 404 to different positioning holes 403, the movable part 402 can be fixed in different positions on the fixed part 401, thereby adjusting the distance between the high-pressure electrode needle 3 and the pure water pressure nozzle 2. At this time, the distance between the high-pressure electrode needle 3 and the pure water pressure nozzle 2 can be adjusted according to the conical area covered by the mist sprayed from the pure water pressure nozzle 2, so that the high-pressure electrode needle 3 is located outside the conical area covered by the mist, avoiding the formation of droplets on the high-pressure electrode needle 3.

[0020] like Figure 4 and Figure 5 As shown, in Embodiment 2, an insulating conical sleeve 6 is provided on the insulating bracket 4 corresponding to each ring of high voltage electrode needle 3. An insulating slider 7 is fixed to the outer end of the high voltage electrode needle 3. The insulating slider 7 is axially slidably mounted on the insulating conical sleeve 6. An adjusting component for adjusting the axial displacement of the insulating slider 7 on the insulating conical sleeve 6 is provided on the insulating conical sleeve 6.

[0021] By operating the adjustment component, the insulating slider 7 can be moved along the axial direction of the insulating cone sleeve 6. At this time, not only can the distance between the high-voltage electrode needle 3 and the pure water pressure nozzle 2 be adjusted, but also the diameter of the annular area enclosed by the high-voltage electrode needle 3 can be adjusted.

[0022] When the high-voltage electrode needle 3 approaches the pure water pressure nozzle 2, it will be close to the top of the cone-shaped area covered by the mist. By setting the insulating cone sleeve 6 into a cone-shaped structure that matches the cone-shaped area covered by the mist, the high-voltage electrode needle 3 moves radially inward, so that the head of the high-voltage electrode needle 3 always maintains an effective distance from the mist. This ensures that the high-voltage electrode needle 3 will not be directly sprayed to form droplets, and also ensures an effective charging effect.

[0023] The adjusting assembly includes an outer insulating ring 8 and an insulating screw 9. The outer insulating ring 8 is axially slidably disposed outside the insulating cone sleeve 6. The outer end of the slider passes through the insulating cone sleeve 6 and is radially slidably sleeved outside the outer insulating ring 8. The insulating screw 9 is rotatably mounted outside the insulating cone sleeve 6. The outer insulating ring 8 and the insulating screw 9 are threadedly engaged. The insulating cone sleeve 6, the insulating slider 7, the outer insulating ring 8, and the insulating screw 9 are all made of insulating and high-voltage resistant materials.

[0024] By rotating the insulating screw 9, the outer insulating ring 8 is displaced. The outer insulating ring 8 simultaneously drives a ring of high-voltage electrode needles 3 on the insulating cone sleeve 6 to move synchronously. The self-locking effect of the insulating screw 9 and the outer insulating ring 8 is used to lock the position of the high-voltage electrode needles 3.

[0025] Optionally, the high-voltage electrode needle 3 is tilted downwards at its tip, which allows the tip of the high-voltage electrode needle 3 to more effectively allow the droplet to detach from the high-voltage electrode needle 3 under its own weight, ensuring stability and safety.

[0026] The spray bracket 1 is equipped with a dust concentration monitor 10 and a harmful gas concentration monitor 11, which are used to detect dust concentration and harmful gas concentration, respectively.

[0027] An overcurrent protector 12 is installed on the power supply circuit of the high-voltage electrode needle 3, which can cut off the power in time when an abnormal situation occurs in the corona discharge, preventing damage to the high-voltage power supply 16 and adverse consequences caused by continuous breakdown discharge.

[0028] It also includes a control box 13, which is equipped with an ambient humidity monitor 14 and an ambient temperature monitor 15, which are used to detect ambient humidity and temperature, respectively.

[0029] The control box 13 contains a high-voltage power supply 16, a voltage and current monitor 17, a signal receiver 18, a micro pump 19, a flow meter 20, and a micro controller 21. The dust concentration monitor 10, the harmful gas concentration monitor 11, the ambient temperature monitor 15, the ambient humidity monitor 14, the flow meter 20, and the voltage and current monitor 17 are all connected to the signal receiver 18 via data cables. A control panel 22 is located outside the control box 13.

[0030] The signal receiver 18 is connected to the microcontroller 21, which in turn is connected to the control panel 22. Real-time monitoring data can be viewed on the control panel 22. The microcontroller 21 is connected to the micropump 19 and the high-voltage power supply 16, and can adjust the water flow rate and voltage.

[0031] It also includes a water tank 23 and a ball valve 24. Both the flow meter 20 and the ball valve 24 are located inside the water circuit between the water tank 23 and the micro pump 19, with the ball valve 24 located upstream of the flow meter 20. The ball valve 24 allows for manual shut-off of the water circuit.

[0032] The control panel 22 allows setting spray activation conditions, such as dust concentration thresholds and harmful gas thresholds. Once the detected dust concentration or harmful gas concentration exceeds the limit, the corona-charged spray device will automatically start operating. During device operation, data from the flow meter 20 and voltage / current monitor 17 can be used to determine if the system is operating normally. The control panel 22 can also set the flow rate and voltage to control the overall operating status of the device. The control panel 22 can also be set to timed spraying, turning the spray on or off at fixed intervals.

[0033] Therefore, the added real-time monitoring system and automatic control system enable the entire device to achieve a high degree of automation, and to provide real-time feedback, control and adjustment for different field conditions.

[0034] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
