[0026] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise indicated, all technical and scientific terms used herein have the same meaning as those commonly understood by one of ordinary skill in the art to which the present application pertains. Furthermore, it should be understood that the use of the terms "include," "includes," "including," "comprise," "comprises," or "comprising" in this specification is intended to mean that the object or items in question are not exhaustive. Rather, they are intended to provide further explanation of the present application.

[0027] To solve the technical problems mentioned in the background art, the present embodiment proposes a cylindrical filter backflush cleaning device, as shown in Figure 1 、 Figure 2 、 Figure 3 The cleaning device includes a dust removal box 15 and a dust fall box 14. The dust removal box 15 is internally provided with a first chamber and a second chamber, and the compressed air bin 3 is installed in the first chamber. The compressed air bin 3 is connected to the blowpipe through the pulse switch valve 1, and the blowpipe is further communicated with the inside of the filter. Through the pulse blow cleaning process, the dust attached in the air is blown out of the filter, ensuring the cleanliness of the filter. The dust fall box 14 is communicated with the second chamber of the dust removal box 15 through the air pipe 9, and the air pipe 9 is provided with an exhaust fan 8, which blows the dust in the dust removal box 15 into the dust fall box 14. The dust fall box 14 is provided with a water curtain pipe 6 at the top, which sprays water mist downward.

[0028] In operation, the pulse switch valve 1 adjusts the blowpipe to inject compressed air into the inside of the filter. Due to the dust accumulation outside the filter, the pulse blow will reverse the compressed air through the filter paper, and the impact of the strong airflow will make the dust attached to the surface of the filter paper vibrate and peel off, thereby achieving the effect of dust removal. The top of the dust fall box 14 is provided with a water curtain pipe 6, which sprays water mist to adsorb dust particles in the air onto the surface of water droplets, and then through the sedimentation effect of water droplets, the particulate matter is deposited at the bottom of the dust fall box 14, forming sewage and being discharged through the sewage outlet 11. This design effectively avoids the secondary pollution of dust. The device combines backflush dust removal and water curtain dust fall, which not only ensures the efficient cleaning of the filter and avoids damage to the filter material, but also improves the long-term operation efficiency of the air treatment equipment and reduces manual maintenance and resource waste.

[0029] The compressed air bin 3 is provided with a compressed air inlet pipe 4, and the pipe is located at the top of the compressed air bin 3, and the top of the pipe protrudes from the first chamber of the dust removal box 15. When the air can smoothly enter the compressed air bin 3, it provides sufficient air source for the subsequent pulse back blow.

[0030] Two pulse switch valves 1 are arranged in the ash removal box 15, respectively on the front and back sides of the compressed air chamber 3, and four filters are arranged in a matrix, with each two filters connected to a pulse switch valve 1. When the pulse switch valve 1 is opened, compressed air is rapidly sprayed into the filter to form a strong airflow to clean the filter paper. Since there are a large number of filters, the matrix arrangement can ensure that each filter is effectively cleaned, while avoiding unnecessary repetition during the cleaning process, ensuring the efficiency and accuracy of the pulse blowing.

[0031] The ash removal box 15 is provided with a partition plate, which divides the ash removal box 15 into a first chamber and a second chamber. In addition, the filter includes a cylindrical section 10 and a conical section 13, wherein one end of the conical section 13 is mounted on the partition plate, and the side of the ash removal box 15 is provided with an access door 5. The design of the conical section 13 is fixed by connecting with the partition plate, which ensures that the filter will not shift during the cleaning process, avoiding structural instability caused by vibration or airflow changes. Further, equipment supports can be added in the second chamber to support the filter.

[0032] The ash removal box 15 is provided with a pulse blowing instrument 2 outside the box wall, which is responsible for controlling the opening and closing of the pulse switch valve 1. The pulse blowing instrument 2 precisely adjusts the intensity and duration of the blowing airflow by controlling the opening time and frequency of the pulse switch valve 1, ensuring that each cleaning process achieves the best effect.

[0033] The air duct 9 has a rectangular air outlet 12, and the air outlet 12 is located in the middle position of the upper and lower filters in the vertical direction. This structure layout facilitates the airflow intake of the exhaust fan 8, ensuring that the wind force during the cleaning process is strong and stable, avoiding the problem of incomplete local cleaning caused by improper position of the air outlet 12.

[0034] The air outlet 12 of the air duct 9 is arranged transversely, and two exhaust fans 8 are arranged transversely in the air outlet 12. This design ensures that the airflow in the air duct 9 can fully expand in the horizontal plane, improving the air flow capacity of the entire cleaning device, which can uniformly and strongly suck the dust in the ash removal box 15 into the dust removal box 14, preventing low cleaning efficiency caused by uneven arrangement of the exhaust fan 8.

[0035] The water inlet pipe 7 is arranged in the dust falling box 14 and communicates with the water curtain pipe 6. The water inlet pipe 7 is exposed from the top of the dust falling box 14 and can provide a continuous water source for the water curtain pipe 6. The water curtain pipe 6 is provided with a plurality of water spray holes and can uniformly spray water mist into the air to contact the dust particles in the air, increase the moisture of the dust, and make it settle. The reasonable arrangement of the water curtain pipe 6 and the design of the water spray holes help to uniformly distribute the water mist and improve the dust falling effect. Through the design, the dust particles can be quickly adsorbed and settled, and finally enter the bottom of the dust falling box 14.

[0036] The bottom of the dust falling box 14 is designed as an inverted cone structure, which can ensure that the water droplets and settled dust particles quickly flow into the bottom of the dust falling box 14. The inverted cone design optimizes the discharge of sewage, so that the accumulated sewage can be smoothly discharged, avoiding the retention of sewage in the dust falling box 14, and ensuring the stability of the equipment during long-term operation.

[0037] The working principle of the dust removal box 15 can be summarized as two steps: back blowing and vibration.

[0038] The dust removal process of the pulse back blowing dust removal box 15 is as follows: when the pulse switch valve 1 is opened, the compressed air in the compressed air bin 3 is blown into the filter through the blowing pipe in a very short pulse time. Because the air containing dust passes through the filter paper from the outside to the inside of the filter, we use the method of back blowing, that is, the compressed air is blown from the inside to the outside through the filter paper, and the filter paper is vibrated by the impact of the compressed air flow, so that the dust deposited on the surface of the filter paper is stripped and falls into the pulse back blowing dust removal box 15.

[0039] The air pipe 9 is connected between the pulse back blowing dust removal box 15 and the water curtain dust falling box 14, and two exhaust fans 8 are arranged in the air pipe 9. The exhaust fans 8 generate negative pressure to suck the dust in the pulse back blowing dust removal box 15 into the water curtain dust falling box 14. The pulse back blowing dust removal box 15 realizes continuous dust removal effect by setting the blowing interval time, blowing pressure and blowing time of the pulse blowing instrument 2. This pulse back blowing method not only has complete blowing effect, but also avoids the secondary adsorption of dust generated by blowing.

[0040] The working principle of the water curtain dust falling box 14 can be summarized as two steps: wetting and settling.

[0041] The wetting process: in the water curtain dust falling box 14, water mist is sprayed into the air through the spraying system, forming fine water droplets. When the dust particles in the air come into contact with the water droplets, the dust particles will be adsorbed on the water droplets due to the surface tension and adhesion of the water droplets. At the same time, the contact between the water droplets and the dust particles also makes the dust particles more humid, increasing the weight and adhesion of the particles.

[0042] The dust particles after wetting will be deposited at the bottom of the water curtain dust box 14 to form sewage flow under the gravity of water drops, and the sewage is discharged from the drain at the bottom of the water curtain dust box 14.

[0043] In this embodiment, the filter to be cleaned is fixed on the bracket of the pulse back-flushing box, the opening of the pulse switch valve 1 is controlled by the pulse controller, the soot is shaken off from the surface of the filter, the negative pressure is generated by the exhaust fan 8 to suck the soot into the water curtain dust box 14, the water curtain in the water curtain dust box 14 absorbs the soot and generates sewage, and the sewage is discharged through the sewage outlet 11. Through continuous spraying and cleaning, four groups of filters can be cleaned at the same time, the filter material is not damaged, and the purpose of high-efficiency cleaning of the filter is achieved.

[0044] Although the specific embodiments of the utility model are described above in combination with the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or deformations made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
