Description

Technical Field

[0001] This utility model belongs to the field of atomized spraying technology, and relates to an atomized spraying device, and more particularly to a centralized two-fluid atomized spraying device. Background Technology

[0002] In many industrial production processes and environmental management fields, it is often necessary to atomize and spray liquids. For example, in chemical production, reaction liquids need to be atomized to allow for full contact and reaction with other gases or substances; in the environmental field, liquids with purification functions need to be atomized to purify the air.

[0003] Traditional single-fluid atomizing spray devices rely solely on the liquid's own pressure to atomize through the nozzle. Their atomization effect is significantly limited by factors such as liquid pressure and nozzle structure. In some cases, it is difficult to produce sufficiently fine and uniform droplets, resulting in a limited contact area with the target object and affecting the treatment effect. While some existing two-fluid atomizing spray devices improve the atomization effect to some extent by introducing gas to assist liquid atomization, they still have many problems.

[0004] Some two-fluid atomizing spray devices have unreasonable gas-liquid mixing structure designs, resulting in insufficient and uneven mixing of gas and liquid, leading to significant differences in droplet size and affecting spray uniformity. Some devices lack flexibility in adjusting the gas-liquid ratio, making it difficult to adapt to varying atomization requirements under different operating conditions. Furthermore, existing devices are structurally complex, resulting in high equipment costs and difficult maintenance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a centralized two-fluid atomizing spray device. It solves the problems of uneven atomization and poor spraying performance in existing systems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A centralized two-fluid atomizing spray device includes an air supply component, a liquid supply component, and several pressure atomizing nozzles. Each pressure atomizing nozzle is connected to the air supply component. The liquid supply component includes a diluent tank, a stock solution tank, and a purified water supply pipeline. The purified water supply pipeline is connected to the diluent tank. A proportioner is installed on the purified water supply pipeline. The stock solution tank is connected to the proportioner through a pipeline. The bottom of the diluent tank is connected to the pressure atomizing nozzles at various locations through a pipeline, and a pump assembly is installed at the pipeline.

[0008] This atomizing spray device consists of three main parts: an air supply component, a liquid supply component, and a pressure atomizing nozzle. The pressure atomizing nozzle is connected to the air supply component and the liquid supply component, which enables more stable and uniform atomizing spray.

[0009] The liquid supply component of this application includes a stock solution tank and a purified water supply pipeline connected to a proportioner. The stock solution is mixed and diluted according to the required ratio. The diluted stock solution is then stored in the dilution tank. The dilution tank is connected to pressure atomizing nozzles at various locations to provide a uniform and stable supply of the diluted stock solution. This results in a more uniform atomization of the diluted stock solution, leading to a better spraying effect.

[0010] In the above-mentioned centralized two-fluid atomizing spray device, the pipeline includes a main pipeline and several branch pipelines, the pump assembly includes a variable frequency pressure stabilizing pump and a valve, the variable frequency pressure stabilizing pump and the valve are both installed on the main pipeline and the valve is located on the side of the branch pipeline, and several pressure atomizing nozzles are connected side by side on each branch pipeline.

[0011] In the above-mentioned centralized two-fluid atomizing spray device, the air supply component includes an air compressor and a compressed air storage tank connected to each other. The compressed air storage tank is connected to an air outlet pipe, which is connected to various pressure atomizing nozzles.

[0012] The air supply component of this application includes an air compressor and a compressed air storage tank. The compressed air generated by the air compressor is stored in the compressed air storage tank to provide a more stable air supply to the pressure atomizing nozzle, resulting in a better atomization spraying effect.

[0013] In the above-mentioned centralized two-fluid atomizing spray device, the air outlet pipe includes a main air pipe and several branch air pipes. Each branch air pipe corresponds to each branch pipe and is arranged in opposite directions, so that the end of the branch air pipe is connected to the pressure atomizing nozzle on the side of the branch pipe closer to the main pipe, and the side of the branch air pipe closer to the main air pipe is connected to the pressure atomizing nozzle on the end side of the branch pipe.

[0014] In this application, the bronchus and branch pipe face each other, are parallel to each other, and are adjacent to each other. This design can balance the hydraulic pressure difference and air pressure difference, which can make atomization more uniform and the atomization amount of each nozzle is balanced, thus improving the atomization spraying effect.

[0015] In the aforementioned centralized two-fluid atomizing spray device, each branch pipe is connected to a solenoid valve and a pressure regulating valve.

[0016] The design of the solenoid valve and pressure regulating valve allows for flexible adjustment of the gas-liquid ratio, enabling precise adjustment of the gas-liquid ratio according to different working conditions to meet diverse atomization needs.

[0017] In the above-mentioned centralized two-fluid atomizing spray device, the purified water supply pipeline includes a domestic water supply end and a filter, and the filter is installed between the domestic water supply end and the proportioner.

[0018] In the above-mentioned centralized two-fluid atomizing spray device, the bottom of the diluent tank is connected to a drain pipe, and a valve is installed on the drain pipe.

[0019] In the above-mentioned centralized two-fluid atomizing spray device, a water pump is installed on the drainage pipe in front of valve two. A circulation pipe is connected laterally to the drainage pipe between the water pump and valve two. The outlet end of the circulation pipe is inserted into the top of the diluent tank. The water pump is kept in an open state.

[0020] This application installs a water pump and a second valve on the drainage pipe, and sets up a circulation pipe between the water pump and the second valve. The water pump is in a normally open state. When drainage or sewage discharge is required, the second valve is opened, and the liquid is discharged normally from the second valve. After the second valve is closed, the water pump draws the liquid back into the diluent tank through the circulation pipe. This can effectively avoid uneven spraying caused by sedimentation in the diluent tank. This dual-purpose pipe can ensure the uniformity of atomized spraying and improve the spraying effect.

[0021] The beneficial effects of this utility model are:

[0022] 1. This atomizing spray device consists of three main parts: an air supply component, a liquid supply component, and a pressure atomizing nozzle. The pressure atomizing nozzle is connected to the air supply component and the liquid supply component to achieve more stable and uniform atomizing spray.

[0023] 2. The liquid supply component of this application prepares and dilutes the stock solution according to the required ratio. The diluted stock solution is then stored in the dilution tank. The dilution tank is connected to the pressure atomizing nozzles at various locations to provide a uniform and stable supply of the diluted stock solution. This results in a more uniform atomization of the diluted stock solution and a better spraying effect. Attached Figure Description

[0027] Example 1

[0028] like Figure 1 The illustrated centralized two-fluid atomizing spray device includes an air supply assembly 1, a liquid supply assembly 2, and several pressure atomizing nozzles 3. Each pressure atomizing nozzle 3 is connected to the air supply assembly 1. The liquid supply assembly 2 includes a diluent tank 21, a stock solution tank 22, and a purified water supply pipeline 23. The purified water supply pipeline 23 is connected to the diluent tank 21, and a proportioning device 24 is installed on the purified water supply pipeline 23. The stock solution tank 22 is connected to the proportioning device 24 through a pipeline. The bottom of the diluent tank 21 is connected to the pressure atomizing nozzles 3 at various locations through a pipe 6, and a pump assembly 5 is installed at the pipe 6. This atomizing spray device consists of three main parts: the air supply assembly 1, the liquid supply assembly 2, and the pressure atomizing nozzles 3. The connection of the pressure atomizing nozzles 3 to the air supply assembly 1 and the liquid supply assembly 2 enables more stable and uniform atomizing spraying. In this application, the original liquid tank 22 and the purified water supply pipeline 23 in the liquid supply component 2 are connected to the proportioner 24 to mix and dilute the original liquid according to the required ratio. The diluted original liquid is then stored in the dilution tank 21. The dilution tank 21 is connected to the pressure atomizing nozzles 3 at various locations to supply the diluted original liquid evenly and stably. This makes the atomized diluted original liquid more uniform and improves the spraying effect.

[0029] The specific structure of the liquid supply assembly 2 is as follows: The purified water supply pipeline 23 includes a domestic water supply end 231 and a filter 232. The filter 232 is installed between the domestic water supply end 231 and the proportioner 24. The filter 232 can filter impurities to improve water quality, prevent pollutants from contaminating the original liquid, and ensure the spraying effect. The bottom of the diluent tank 21 is connected to a drain pipe 7, and a valve 2 71 is installed on the drain pipe 7. The pipeline 6 includes a main pipeline 61 and several branch pipelines 62. The pump assembly 5 includes a variable frequency pressure stabilizing pump 51 and a valve 1 52. The variable frequency pressure stabilizing pump 51 and the valve 1 52 are both installed on the main pipeline 61, with the valve 1 52 on the side where the branch pipeline 62 is located. Each branch pipeline 62 is connected to three pressure atomizing nozzles 3 arranged side by side.

[0030] The specific structure of the air supply assembly 1 is as follows: The air supply assembly 1 includes an air compressor 12 and a compressed air storage tank 11 connected to each other. An air outlet pipe 4 is connected to the compressed air storage tank 11, and the air outlet pipe 4 is connected to various pressure atomizing nozzles 3. The air supply assembly 1 of this application includes an air compressor 12 and a compressed air storage tank 11. The compressed air generated by the air compressor 12 is stored in the compressed air storage tank 11 to provide a more stable air supply to the pressure atomizing nozzles 3, resulting in a better atomization spraying effect. The air outlet pipe 4 includes a main air pipe 41 and several branch air pipes 42. Each branch pipe corresponds to each branch pipe 62 and is arranged in opposite directions, so that the end of the branch pipe 42 is connected to the pressure atomizing nozzle 3 on the side of the branch pipe 62 closest to the main air pipe 61, and the side of the branch pipe 42 closest to the main air pipe 41 is connected to the pressure atomizing nozzle 3 on the end side of the branch pipe 62. In this application, the branch pipe 42 and branch pipe 62 face each other, are parallel to each other, and are adjacent to each other end to end. Taking one of the main pipes 61 as an example, pressure atomizing nozzles 3, numbered 1, 2, and 3, are connected evenly from left to right. No. 1 is closest to the main pipe 61, followed by No. 2, and No. 3 is the farthest. Therefore, when liquid is discharged, the pressure and flow rate at position 1 are slightly higher than those at positions 2 and 3. After the branch pipe 42 is connected to No. 1, 2, and 3 from left to right, position 1 is the farthest from the main pipe 41 and has the lowest pressure, while position 3 is the closest and has the highest pressure. This balance between air pressure and hydraulic pressure allows for more uniform atomization and a more even atomization volume from each nozzle, improving the atomization spraying effect. Furthermore, each branch pipe 42 is connected to a solenoid valve 43 and a pressure regulating valve 44. The design of the solenoid valve 43 and the pressure regulating valve 44 allows for flexible adjustment of the gas-liquid ratio, enabling precise adjustment of the gas-liquid ratio according to different working conditions to meet diverse atomization needs.

[0031] Example 2

[0032] like Figure 2 As shown, the other structures in this embodiment are basically the same as in Embodiment 1, except that: a water pump 72 is installed on the drainage pipe 7 in front of valve 2 71, and a circulation pipe 73 is connected laterally to the drainage pipe 7 between the water pump 72 and valve 2 71. The outlet end of the circulation pipe 73 is inserted into the top of the diluent tank 21, and the water pump 72 is kept open. In this application, a water pump 72 and valve 2 71 are installed on the drainage pipe 7, and a circulation pipe 73 is set between the water pump 72 and valve 2 71. The water pump 72 is in a normally open state. When drainage or sewage discharge is required, valve 2 71 is opened, and the liquid is normally discharged from valve 2 71. After valve 2 71 is closed, the water pump 72 draws the liquid back into the diluent tank 21 from the circulation pipe 73. This can effectively avoid uneven spraying caused by sedimentation in the diluent tank 21. This dual-purpose pipe can ensure the uniformity of atomized spraying and improve the spraying effect.
