[0029] An embodiment of the present application provides a charged high-pressure atomizer, see Figure 1 and Figure 2 The charged high-pressure atomizer includes a charging module 10 and an atomizing body 20 .

[0030] The charging module 10 includes a high-voltage charger 11 and a discharge needle 12 . The high-voltage charger 11 is electrically connected to the discharge needle 12 so that the discharge needle 12 performs corona discharge to form a corona charging area.

[0031] The atomizing body 20 includes a material storage tank 21 and a spray gun 22. The spray gun 22 is connected to the material storage tank 21 to atomize the liquid from the material storage tank 21. The discharge needle 12 is arranged at the spray gun 22 so that the liquid atomized by the spray gun 22 passes through the corona charging zone.

[0032] Specifically, the charging module 10 refers to a structure capable of forming a corona charging zone. The high-voltage charger 11 generates a high voltage to provide electrical energy to the discharge needle 12, enabling it to perform corona discharge to ionize the air. The atomized liquid passes through the corona charging zone and is charged with the same charge as the high-voltage discharge needle 12.

[0033] The voltage range output by the high-voltage charger 11 is not limited.

[0034] For example, the voltage output by the high-voltage charger is greater than or equal to 10 kV and less than or equal to 100 kV. For example, the voltage output by the high-voltage charger 11 is 10 kV, 20 kV, 30 kV, 40 kV, 50 kV, 60 kV, 70 kV, 80 kV, 90 kV or 100 kV. Thus, by maintaining the voltage output by the high-voltage charger 11 within the above range, the discharge needle 12 can more effectively perform corona discharge to ionize the air.

[0035] The discharge needle 12 refers to a component electrically connected to the high-voltage charger 11 to perform corona discharge to form a corona charging area.

[0036] The structure type of the discharge needle 12 is not limited. For example, the discharge needle 12 is a conductive structure with a sharp tip at one end. Under the action of high voltage, the electric field intensity near the tip is extremely high, which can ionize the surrounding air molecules and generate a corona discharge phenomenon. Since one end of the discharge needle 12 is a sharp tip, the efficiency of the corona discharge can be improved.

[0037] The atomizing body 20 is an atomizing device that can atomize the liquid in the storage tank 21 into small droplets and spray the small droplets.

[0038] The material storage tank 21 is a material storage container for storing material liquid.

[0039] The material type of the storage tank 21 is not limited.

[0040] For example, the material type of the storage tank 21 is stainless steel, thereby enabling the storage tank 21 to have better corrosion resistance.

[0041] The type of liquid structure in the storage tank 21 is not limited.

[0042] For example, the liquid in the storage tank 21 is a fixing agent.

[0043] The number of the material storage tanks 21 is not limited. Only one material storage tank 21 may be provided, or a plurality of material storage tanks 21 may be provided.

[0044] Exemplarily, the atomizing body 20 includes a plurality of storage tanks 21, and the spray gun 22 has a connecting port. That is, the plurality of storage tanks 21 are connected through a connecting port, so that the liquid in each storage tank 21 enters the spray gun 22 through the connecting port, which can simplify the structure.

[0045] Exemplarily, the atomizing body 20 includes a plurality of storage tanks 21, and the spray gun 22 has a plurality of communication ports corresponding to the storage tanks 21. In other words, each storage tank 21 enters the spray gun 22 from a different communication port, which can improve the efficiency of the liquid in the storage tank 21 entering the spray gun 22.

[0046] It should be noted that when the atomizing body 20 includes a plurality of storage tanks 21, according to actual conditions, the same liquid feed can be stored in each storage tank 21. Of course, different types of liquid feed can also be stored, thereby achieving the purpose of synchronously atomizing multiple different types of liquid feeds.

[0047] The fixative is also called spray liquid, which is an atomizing medium. The fixative is sprayed into the air after being atomized to contact with the aerosol particles in the air to condense, thereby separating the aerosol particles from the air.

[0048] The atomizing body 20 can atomize the liquid feed to form droplets with an average particle size of micrometers, so that the average particle size of the droplets after the liquid feed is atomized is close to the particle size of the radioactive aerosols in the environment, thereby enabling the droplets to better fix and control the radioactive aerosols.

[0049] The spray gun 22 is a component for atomizing the feed liquid and spraying the feed liquid into the external air.

[0050] For example, the atomizing body 20 can atomize the fixative to form droplets with an average particle size in the micrometer range, so that the average particle size of the atomized fixative droplets is close to the particle size of the radioactive aerosols in the environment, thereby enabling the droplets to better fix and control the radioactive aerosols.

[0051] It should be noted that the charged high-pressure atomizer can atomize a liquid with a viscosity of 1000cp (centipoise, a unit of viscosity, the viscosity of water at 20°C is 1cp) into droplets with a particle size in the micron range. At the same time, the spraying distance is greater than 3m, the atomization volume is ≥2l / min, and the charge can reach 2C / kg, thereby meeting the demand for rapid control of radioactive aerosols that spread outside the factory.

[0052] The charged high-pressure atomizer of the embodiment of the present application includes a charging module 10 and an atomizing body 20. The charging module 10 includes a high-voltage charger 11 and a discharge needle 12, and the high-voltage charger 11 is electrically connected to the discharge needle 12 so that the discharge needle 12 performs corona discharge to form a corona charging zone. The atomizing body 20 includes a storage tank 21 and a spray gun 22, and the spray gun 22 is connected to the storage tank 21 to atomize the liquid from the storage tank 21, and the discharge needle 12 is arranged at the spray gun 22 so that the liquid atomized by the spray gun 22 passes through the corona charging zone. Therefore, on the one hand, the discharge needle 12 is arranged at the spray gun 22, and the liquid atomized by the spray gun 22 passes through the corona charging zone, which can significantly increase the charge of the liquid, thereby effectively improving the electrostatic adsorption effect on the aerosol, reducing its suspension time and diffusion range in the air, and thus reducing the harm to the environment and the public. On the other hand, for open areas such as outside the factory where a large amount of fixative needs to be atomized in a short period of time, the charging speed of corona charging can better meet the requirements.

[0053] In one embodiment, please refer to Figure 1 and Figure 2 The charged high-pressure atomizer further includes a control component 30, which includes a processor 31, and the processor 31 is connected to the high-pressure charger 11 by signal to adjust the voltage of the high-pressure charger 11. Thus, the voltage of the high-pressure charger 11 can be adaptively adjusted according to the different liquids in the storage tank 21, so that the discharge needle 12 generates a corona discharge of appropriate intensity, so that the liquid after atomization obtains an appropriate charge, thereby maximizing the condensation efficiency with the radioactive aerosol and achieving effective control of the radioactive aerosol.

[0054] It should be noted that different types and viscosities of liquids have different optimal charging voltages. The processor 31 adjusts the charging voltage according to the different liquids, thereby enabling the atomized liquid to obtain a higher charging intensity.

[0055] In one embodiment, please refer to Figure 1 and Figure 2 The charging module 10 further includes a telescopic bracket, which is arranged at the spray gun 22, the spray gun 22 has a nozzle, the discharge needle 12 is arranged on the telescopic bracket, and the processor 31 is connected to the telescopic bracket signal to adjust the distance of the discharge needle 12 relative to the nozzle through the telescopic bracket. Thus, according to the different liquid in the storage tank 21, the distance of the discharge needle 12 relative to the nozzle can be adaptively adjusted, thereby optimizing the charging effect of the liquid after the material is atomized.

[0056] Specifically, the telescopic bracket refers to a component that can change its own length by telescoping.

[0057] It should be noted that different types and viscosities of liquids have different optimal charging distances. The processor 31 adjusts the distance between the discharge needle 12 and the nozzle according to the different liquids, thereby enabling the atomized liquid to obtain a higher charging intensity.

[0058] It is understandable that the processor 31 is connected to the telescopic bracket signal, and the processor 31 can adjust the telescopic bracket to a suitable length before the charged high-pressure atomizer works. The length of the telescopic bracket can also be adaptively adjusted according to the atomization effect of the liquid during the operation of the charged high-pressure atomizer.

[0059] In a specific embodiment, the processor 31 has a control panel 33, and the control panel 33 can integrate relevant parameters such as the liquid parameters, the distance between the discharge needle 12 and the nozzle, the output voltage of the high-voltage charger 11 and the target atomization particle size, so that the operator can set it, so that the processor 31 can automatically adjust the various components in the charged high-voltage atomizer that are connected to the signal according to the set parameters. It is easy to operate, has a stable atomization effect, and can improve the accuracy of the atomization particle size.

[0060] In one embodiment, please refer to Figure 1 and Figure 2 The atomizing body further includes a liquid level sensor 23 disposed in the storage tank 21 , and the processor 31 is connected to the liquid level sensor 23 signal to monitor the hydraulic pressure in the storage tank 21 .

[0061] Specifically, by providing the liquid level sensor 23, the hydraulic pressure in the storage tank 21 can be detected, and the liquid level in the storage tank 21 can be measured. By connecting the processor 31 to the liquid level sensor 23 signal, the hydraulic pressure and liquid level in the storage tank 21 can be monitored online, so as to adjust the flow rate of the material liquid entering the spray gun 22.

[0062] In one embodiment, please refer to Figure 1 and Figure 2 The atomizing body 20 further includes a high-pressure pump 24, which is connected to the storage tank 21 and the spray gun 22, respectively, so that the liquid feed is sprayed out from the spray gun 22 through the high-pressure pump 24. Thus, the high-pressure pump 24 can provide a stable and sufficiently high pressure for the liquid feed, so that the liquid feed can be stably atomized into tiny droplets at the spray gun 22.

[0063] Specifically, the number of the high-pressure pumps 24 is not limited, and only one high-pressure pump 24 may be provided, or a plurality of high-pressure pumps 24 may be provided.

[0064] Exemplarily, the atomizing body 20 includes a plurality of material storage tanks 21 and a high-pressure pump 24, and the high-pressure pump 24 is simultaneously connected to the plurality of material storage tanks 21. Thus, the structure can be simplified.

[0065] Exemplarily, the atomizing body 20 includes a plurality of storage tanks 21 and a plurality of high-pressure pumps 24 connected one by one with the storage tanks 21. Thus, the flow rate and pressure of each storage tank 21 can be accurately adjusted, so that the liquid in each storage tank 21 can be atomized and other subsequent treatments with stable and accurate parameters.

[0066] In one embodiment, please refer to Figure 2 The bottom of the storage tank also has a discharge port 21a that can be opened and closed.

[0067] Specifically, the bottom of the material storage tank 21 has a discharge port 21a, and when the charged high-pressure atomizer is in the working state, the discharge port 21a is closed to seal the material storage tank 21. After the charged high-pressure atomizer has finished working, when it is necessary to discharge the remaining liquid in the material storage tank 21, the discharge port 21a can be opened to discharge the remaining liquid in the material storage tank 21.

[0068] In addition, the discharge port 21a can also be used to facilitate the discharge of waste water after cleaning when the storage tank 21 is cleaned.

[0069] In one embodiment, please refer to Figure 1 and Figure 2The atomizing body 20 further includes a high-pressure pump 24, which is connected to the storage tank 21 and the spray gun 22 respectively, so that the liquid feed is sprayed out from the spray gun 22 through the high-pressure pump 24. The control component 30 further includes a flow meter 32, which is arranged on the discharge pipeline connected to the high-pressure pump 24 and the spray gun 22. The flow meter 32 is connected to the processor 31 by signal to monitor the liquid feed flow in the discharge pipeline. Therefore, through the real-time monitoring of the liquid feed flow in the discharge pipeline by the flow meter 32 and the precise control of the processor 31 based on the flow data, the supply of the liquid feed in the atomization process can be kept in the best state at all times, thereby improving the collision and condensation efficiency with the radioactive aerosol and achieving effective control of the radioactive aerosol.

[0070] Specifically, the location where the flow meter 32 is disposed on the discharge pipeline is not limited.

[0071] For example, the flow meter 32 is disposed on the discharge pipeline and is located at one end close to the spray gun 22 .

[0072] The flow meter 32 can monitor the flow of the liquid in the discharge pipeline, and by connecting the signal with the processor 31, it can realize online monitoring of the liquid flow, so that the operator can watch it, thereby improving the efficiency of the operator's remote work.

[0073] In a specific embodiment, the control component 30 also includes a camera, a flow meter 32 and a liquid level sensor 23 for real-time display of the output volume. The cameras on the front, back, left and right sides of the device can ensure the stability of the atomization particle size and the atomization effect, while improving the efficiency of the operator working at a distance.

[0074] In one embodiment, please refer to Figure 1 and Figure 2 The charged high-pressure atomizer includes a feed module 40, which includes an air supply system 41, a solenoid valve and a delivery pump 42. The solenoid valve is connected to the air supply system 41 and the delivery pump 42 respectively to control the opening and closing of the delivery pump 42. The delivery pump 42 is connected to the storage tank 21 through a feed pipeline to deliver liquid to the storage tank 21. Therefore, the solenoid valve cooperates with the air supply system 41 to control the opening and closing of the delivery pump 42, so as to realize the start and stop control of the liquid delivery. According to factors such as the liquid level height of the liquid in the storage tank 21 and the working state of the charged high-pressure atomizer, the processor 31 can accurately send a signal to the solenoid valve, so as to control the working time and delivery amount of the delivery pump 42, and ensure that the liquid in the storage tank 21 is always kept within a suitable liquid level range, so that neither overflow or excessive pressure will be caused by too much liquid, nor the normal operation of the atomizer will be affected by too little liquid.

[0075] Specifically, the feed module 40 refers to a functional unit in the charged high-pressure atomizer that is responsible for transporting the feed liquid to the storage tank 21 .

[0076] The solenoid valve refers to a device for controlling the opening and closing of the passage between the gas supply system 41 and the delivery pump 42. The feeding speed of the material liquid in the storage tank 21 can be adjusted by the solenoid valve.

[0077] The delivery pump 42 refers to a device for delivering the feed liquid from an external source to the storage tank 21 .

[0078] The type of the delivery pump 42 is not limited.

[0079] Exemplarily, the atomizing body 20 includes two material storage tanks 21 , and the delivery pump 42 is a two-component delivery pump 42 , and the two components are respectively connected to each material storage tank 21 to deliver different liquids to each material storage tank 21 .

[0080] The pressure of the delivery pump 42 can be adaptively adjusted according to the type of the delivered liquid.

[0081] In addition, the feed module 40 may further include other structures.

[0082] For example, the feed module 40 further includes a filter screen disposed on the feed pipeline. By providing the filter screen, foreign matter that may be present in the feed liquid can be filtered, thereby reducing the risk of the spray gun 22 being blocked.

[0083] In one embodiment, please refer to Figure 2 The control assembly further includes a control valve 34, which is disposed on the discharge pipeline to control the flow rate of the liquid in the discharge pipeline. Thus, the control valve 34 can adjust its opening according to different processing requirements to control the flow rate of the liquid in the discharge pipeline, thereby obtaining a better atomization effect.

[0084] Specifically, in the process of treating radioactive aerosols, different working conditions (such as aerosols of different concentrations and different diffusion ranges) require different atomization amounts. The control valve 34 can accurately adjust the liquid flow rate according to the instructions of the processor 31, thereby ensuring that the droplet particle size, quantity and other parameters generated by the atomization meet the optimal treatment requirements, improve the collision and condensation efficiency with the radioactive aerosol, and achieve effective control of the radioactive aerosol.

[0085] In one embodiment, please refer to Figure 2 The atomizing body 20 includes a plurality of material storage tanks 21 , the spray gun 22 includes a spray gun 22 body and a mixer 25 , the spray gun 22 body has a spray head, and the spray head is respectively connected to each material storage tank 21 and the mixer 25 to mix the material liquid from each material storage tank 21 through the mixer 25 .

[0086] Specifically, by setting up the mixer 25, the purpose of mixing the liquid from each storage tank 21 can be achieved, which can facilitate the nozzle to evenly atomize the mixed liquid, so that the properties of the small droplets formed after atomization are stable, thereby making the atomization effect more stable.

[0087] The spray gun 22 body has a liquid flow channel. One end of the spray gun 22 body is connected to the material storage tank 21, and the liquids in the material storage tanks 21 are mixed in the flow channel of the spray gun 22 body and then sprayed out through the nozzle.

[0088] In one embodiment, please refer to Figure 1 and Figure 2 The charged high-pressure atomizer also includes a mobile module 50, which includes a housing 51, a drive motor 55, a power supply assembly 54, a load-bearing wheel 52 and a track 53. The charged module 10, the atomizing body 20, the drive motor 55 and the power supply assembly 54 are all arranged in the housing 51, and the housing 51 is arranged on the load-bearing wheel 52, and the load-bearing wheel 52 drives the track 53 to move so that the charged high-pressure atomizer moves. Therefore, on the one hand, through the mobile module 50, the charged high-pressure atomizer can move freely in different areas without being restricted by a fixed installation position. On the other hand, the mobile design of the track 53 enables the device to travel smoothly in various complex terrains, so that the charged high-pressure atomizer has good terrain adaptability.

[0089] Specifically, the charging module 10, the atomizing body 20, the driving motor 55 and the power supply assembly 54 are all installed in the housing 51, and the housing 51 is connected to the track 53 through the load-bearing wheel 52. The power supply assembly 54 provides electric energy to the driving motor 55, and the driving motor 55 drives the load-bearing wheel 52 to rotate. Due to the meshing relationship between the track 53 and the load-bearing wheel 52, the rotation of the load-bearing wheel 52 causes the track 53 to generate relative movement on the ground, thereby driving the entire charged high-pressure atomizer to move.

[0090] The power supply assembly 54 is used to provide electrical energy to the drive motor 55 and other structures.

[0091] In a specific embodiment, the mobile module 50 includes an inverter, the driving motor 55 is an AC motor, the power supply component 54 provides a DC power supply, which is converted by the inverter and output by the AC motor as torque. The mobile module 50 adopts a closed-loop control algorithm of a dual-electrode independent control scheme and a multi-mode control method, including remote control control, speed loop control, and displacement loop control.

[0092] In a specific embodiment, the mobile module 50 includes a shock absorbing system (a combination of Matilda suspension and Christie shock absorbing), which cooperates with the crawler 53 to enable the device to cross a 10 cm step when fully loaded.

[0093] In a specific embodiment, the mobile module 50 also includes a remote controller, and the processor 31 is respectively connected to the remote controller and the drive motor 55 by signal, so that the operator can control other structures of the charged high-pressure atomizer through the remote controller.

[0094] In one embodiment, the atomizing body 20 further includes a lifting folding arm 26. Part of the top area of ​​the shell 51 is recessed to form a receiving groove. One end of the lifting folding arm 26 is connected to the shell 51, and the other end is connected to the spray gun 22. The lifting folding arm 26 has a storage state and a use state. When the lifting folding arm 26 is in the storage state, at least part of the lifting folding arm 26 is located in the receiving groove. When the lifting folding arm 26 is in the use state, the lifting folding arm 26 extends from the receiving groove so that the spray gun 22 sprays and covers the target area, so that the charged high-pressure atomizer meets the radioactive aerosol processing requirements of different heights and ranges.

[0095] Specifically, by adjusting the extension height and angle of the lifting and folding arm 26, the atomized and charged liquid can be delivered to the target position, effectively improving the control efficiency and treatment effect of the radioactive aerosol. In addition, during non-operating periods, the lifting and folding arm 26 can be stored in the receiving tank, which can reduce the overall space occupied by the equipment and facilitate the mobile transportation and storage management of the equipment.

[0096] In one embodiment, please refer to Figure 3 , the atomized particle size of the water-based fixative with a viscosity of 1000cp was measured using an optical atomization particle size analyzer. The measurement results are shown in the following table:
