Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, specifically to an air filtration and dust removal device. Background Technology

[0002] Air filtration and dust removal technology is widely used in industrial production, environmental protection, and indoor air quality improvement. It aims to effectively remove particulate pollutants from the air to protect equipment, the environment, and human health. Currently, air filtration and dust removal devices on the market have simple filtration structures and can only remove fine dust particles from the air, resulting in low-quality filtered air. This leads to poor air filtration performance. In addition, the filters in existing air filtration and dust removal devices are prone to clogging and are difficult to clean, which greatly reduces the air filtration effect. Therefore, an air filtration and dust removal device is proposed. Utility Model Content

[0003] The main objective of this invention is to provide an air filtration and dust removal device that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An air filtration and dust removal device includes a dust removal device body, an air inlet pipe fixedly connected to one side of the dust removal device body, an output end of the air inlet pipe fixedly connected to one end of an air collecting hood, the air collecting hood being disposed inside the dust removal device body, and the side of the air collecting hood away from the air inlet pipe being attached to one side of the filter screen.

[0006] A water inlet pipe is inserted into the top of the dust removal device body. A spray head is provided on the inner top of the dust removal device body. There are multiple spray heads, and the multiple spray heads are connected to the inside of the water inlet pipe. A first partition is fixedly connected to the inner top of the dust removal device body. There are two first partitions. A second partition is fixedly connected to the inner bottom of the dust removal device body. There are two second partitions. The two first partitions and the two second partitions are arranged alternately in sequence.

[0007] By adopting the above technical solution, the filter screen initially filters out fine dust, and then the spray head generates water mist to combine with particulate pollutants and cause them to settle. Combined with the tortuous airflow channel formed by the first and second baffles, the air residence time is extended, and the air is fully contacted for purification. The air detector monitors in real time, and the air that does not meet the standards can be circulated through the fan and return pipe until it meets the standards, ensuring the quality of the discharged air.

[0008] Specifically, a fan is fixedly installed on one side of the dust removal device body, and return pipes are fixedly connected to both ends of the fan. The ends of the two return pipes away from the fan are fixedly inserted into one side of the dust removal device body.

[0009] By adopting the above technical solution, the fan re-transports the substandard air back to the starting point of the spray dust removal device body through the return pipe.

[0010] Specifically, an air outlet pipe is provided on the side of the dust removal device body away from the air inlet pipe, and electromagnetic valves are fitted on the outside of the air outlet pipe and the two return pipes.

[0011] By adopting the above technical solution, the treated air is discharged from the dust removal device body through the exhaust pipe. The electromagnetic valve can adjust the opening and closing state of the exhaust pipe to control the air discharge. At the same time, the electromagnetic valve is also used to control the airflow of the return pipe to realize the air circulation treatment.

[0012] Specifically, a water collection tank is provided directly below the dust removal device body. The water collection tank is connected to the dust removal device body through a drain pipe and is internally connected. Multiple drain pipes are provided.

[0013] By adopting the above technical solution, the water collection tank collects water droplets containing pollutants that settle inside the dust removal device through the drain pipe. Multiple drain pipes ensure smooth drainage and prevent water accumulation from affecting the dust removal effect.

[0014] Specifically, the top of the dust removal device body is provided with an installation groove for vertical insertion of the filter screen, a sealing ring is fitted on the upper outer side of the filter screen, and a handle is fixedly connected to the top of the filter screen.

[0015] By adopting the above technical solution, users can vertically insert the filter screen into the installation groove using the handle. The sealing ring ensures the seal between the filter screen and the installation groove, preventing unfiltered air leakage. This design facilitates the installation and replacement of the filter screen and makes maintenance convenient.

[0016] Specifically, an air detector is provided on one side of the dust removal device body below the air outlet pipe, and the detection end of the air detector is located inside the dust removal device body.

[0017] By adopting the above technical solution, the air detector monitors the air quality inside the dust removal device in real time. Its detection end is located below the outlet pipe and one of the return pipes, which can accurately detect whether the treated air meets the standards.

[0018] The beneficial effects of this utility model are:

[0019] The air filtration and dust removal device described in this utility model initially filters out fine dust through a filter screen, and then uses a spray head to generate water mist to combine with particulate pollutants and cause them to settle. In conjunction with the tortuous airflow channel formed by the first and second baffles, the air residence time is extended, allowing for full contact and purification. An air detector monitors in real time, and substandard air can be circulated through a fan and return pipe until it meets the standards, ensuring the quality of the discharged air.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As one embodiment of this utility model, such as Figures 1-3 As shown, the air filtration and dust removal device of this utility model includes a dust removal device body 6. An air inlet pipe 1 is fixedly connected to one side of the dust removal device body 6. The output end of the air inlet pipe 1 is fixedly connected to one end of the air collecting hood 2. The air collecting hood 2 is located inside the dust removal device body 6. The side of the air collecting hood 2 away from the air inlet pipe 1 is attached to the side of the filter screen 3.

[0027] A water inlet pipe 4 is inserted into the top of the dust removal device body 6. A spray head 5 is provided on the inner top of the dust removal device body 6. There are multiple spray heads 5, and the multiple spray heads 5 are connected to the inside of the water inlet pipe 4. A first partition 9 is fixedly connected to the inner top of the dust removal device body 6. There are two first partitions 9. A second partition 12 is fixedly connected to the inner bottom of the dust removal device body 6. There are two second partitions 12. The two first partitions 9 and the two second partitions 12 are arranged alternately in sequence.

[0028] In operation, air containing particulate pollutants is delivered into the dust collector body 6 through the inlet pipe 1. The inlet pipe 1 serves as the air intake channel, ensuring a stable airflow. The output end of the inlet pipe 1 is connected to the air collection hood 2, allowing the air to be evenly guided to the filter screen 3, improving filtration efficiency. The water inlet pipe 4 introduces water into the inner top of the dust collector body 6, forming water mist through multiple spray nozzles 5. This water mist combines with the particulate pollutants in the air, increasing their weight and making them easier to settle, thereby achieving the purpose of dust removal. The first baffle 9 and the second baffle 12 are arranged alternately, forming a tortuous airflow channel. This structure prolongs the residence time of air in the device, giving the water mist more opportunities to contact the particulate pollutants and improving the dust removal effect.

[0029] The present invention also includes a fan 14 fixedly installed on one side of the dust removal device body 6, and a return pipe 13 fixedly connected to both ends of the fan 14, with the ends of the two return pipes 13 away from the fan 14 fixedly inserted into one side of the dust removal device body 6.

[0030] During use, the fan 14 re-transports the substandard air back to the spray dust removal starting point of the dust removal device body 6 through the return pipe 13.

[0031] The present invention also includes an exhaust pipe 7 provided on the side of the dust removal device body 6 away from the air inlet pipe 1, and an electromagnetic valve 15 is sleeved on the outside of the exhaust pipe 7 and the two return pipes 13.

[0032] During use, the treated air is discharged from the dust removal device body 6 through the air outlet pipe 7. The solenoid valve 15 can adjust the opening and closing state of the air outlet pipe 7 to control the air discharge. At the same time, the solenoid valve 15 is also used to control the airflow of the return pipe 13 to realize the air circulation treatment.

[0033] The present invention also includes a water collection tank 11 located directly below the dust removal device body 6. The water collection tank 11 is connected to the dust removal device body 6 via a drain pipe 10 and is internally connected. The drain pipe 10 has multiple pipes.

[0034] During use, the water collection tank 11 collects water droplets containing pollutants that settle inside the dust removal device body 6 through the drain pipe 10. Multiple drain pipes 10 ensure smooth drainage and prevent water accumulation from affecting the dust removal effect.

[0035] The present invention also includes a mounting groove 16 at the top of the dust removal device body 6, the mounting groove 16 being used for vertical insertion of the filter screen 3, a sealing ring 17 being fitted on the upper outer side of the filter screen 3, and a handle 18 being fixedly connected to the top of the filter screen 3.

[0036] When in use, the user can vertically insert the filter screen 3 into the mounting groove 16 through the handle 18. The sealing ring 17 ensures the seal between the filter screen 3 and the mounting groove 16 to prevent unfiltered air leakage. This design facilitates the installation and replacement of the filter screen 3 and makes maintenance convenient.

[0037] The present invention also includes an air detector 8 located on one side of the dust removal device body 6 below the air outlet pipe 7, and the detection end of the air detector 8 is located inside the dust removal device body 6.

[0038] During use, the air detector 8 monitors the air quality inside the dust removal device body 6 in real time. Its detection end is located below the air outlet pipe 7 and one of the return pipes 13, and it can accurately detect whether the treated air meets the standards.

[0039] It should be noted that, based on the test results, the control system can automatically adjust the working status of the solenoid valve 15 and the fan 14 through a pre-edited program to achieve an intelligent dust removal process.

[0040] In use, air containing particulate pollutants is discharged into the dust collector body 6 through the air inlet pipe 1. After being guided by the air collecting hood 2, it is sprayed onto one side of the filter screen 3. The filter screen 3 first performs preliminary filtration of the fine dust in the air. The filtered air continues to flow inside the dust collector body 6. At this time, the water inlet pipe 4 delivers water to multiple spray nozzles 5 at the top inside. The spray nozzles 5 spray water mist that combines with the particulate pollutants in the air, increasing their weight and facilitating their settling. The second partition 12 at the bottom and the first partition 9 at the top inside the dust collector body 6 are arranged alternately to form a tortuous airflow channel, prolonging the residence time of the air in the device and allowing the water mist to fully contact the particulate pollutants. To improve dust removal efficiency, after the air passes through the spray dust removal system, water droplets containing pollutants will settle to the bottom of the device and be discharged into the water collection tank 11 below through multiple drain pipes 10. When the air after the spray dust removal reaches the detection point of the air detector 8, if the air quality meets the standard, the solenoid valve 15 of the outlet pipe 7 can be opened to allow the air to be discharged from the dust removal device body 6 through the outlet pipe 7. If the quality does not meet the standard, the solenoid valves 15 of the two return pipes 13 are opened and the fan 14 is started, so that the fan 14 draws the air near the air detector 8 back to the starting point of the spray dust removal through the return pipes 13 for another dust removal until the air quality meets the standard.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
