[0002] During the industrial production process, a large amount of dust-laden gas is generated. If these dust-laden gases are directly discharged into the environment, they will cause serious environmental pollution and also affect the health of operators. Therefore, it is necessary to effectively treat the dust-laden gas to meet environmental emission standards.

[0003] Traditional filter element cleaning devices often have some shortcomings. Some dust removal equipment can only achieve simple filtering and dust removal functions. They cannot effectively adsorb and treat some harmful substances such as dioxins, mercury vapor and SO2, and cannot meet increasingly stringent environmental protection requirements. At the same time, the cleaning methods used by some filter element cleaning devices are not ideal and cannot promptly and thoroughly remove dust on the surface of the filter element. This not only affects the filtration efficiency of the filter element, but also greatly shortens the service life of the filter element due to dust accumulation. For this reason, we urgently need to provide a pulse vibration cleaning device for the filter element.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application discloses a pulse vibration dust cleaning device for a filter element, referring to Figure 1-Figure 4, including, filter cartridge dust removal tank 1, the bottom side of the filter cartridge dust removal tank 1 is fixedly connected to the air inlet pipe 2, the upper end side of the filter cartridge dust removal tank 1 is fixedly connected to the air outlet pipe 3, the bottom of the filter cartridge dust removal tank 1 is fixedly connected to the cone 4, the bottom of the cone 4 is connected to the dust collecting bucket 5, the middle part of the filter cartridge dust removal tank 1 is fixedly connected to the perforated plate 8, the inner side of the perforated plate 8 is penetrated by a plurality of filter elements 91, the middle part of the filter cartridge dust removal tank 1 is provided with a plurality of air injection pipes 92, the outer ends of the plurality of air injection pipes 92 are penetrated through the outside of the filter cartridge dust removal tank 1 and are connected to the external air source, the inner sides of the plurality of air injection pipes 92 are fixed A blow pipe 94 is fixedly connected, and the bottoms of the multiple blow pipes 94 correspond to the multiple filter elements 91 respectively. By setting an activated carbon filter layer 11 on the upper end of the inner wall of the filter cartridge dust removal tank 1, the dust-laden gas is initially filtered by the filter element 91 and then passes through the activated carbon filter layer 11, which can further adsorb harmful substances such as dioxins, mercury vapor and SO2, thereby realizing the integration of filtration dust removal and adsorption purification, effectively improving the purification effect of the dust-laden gas and reducing pollution to the environment. The upper ends of the multiple blow pipes 94 are all provided with a pulse electromagnetic valve 93. When it is necessary to clean the filter element 91, the pulse electromagnetic valve When the valve 93 is opened, the compressed air from the external air source enters through the air injection pipe 92 and is then sprayed toward the filter element 91 through the blowing pipe 94. Since the spraying direction is opposite to the flow direction of the dust-laden gas, the filter element 91 is vibrated under the action of the reverse airflow, thereby peeling off the dust attached to the outer surface of the filter element 91, and the dust falls into the cone 4 and the dust collecting bucket 5 below. Under the action of the reverse airflow, the dust on the surface of the filter element 91 can be removed in a timely and effective manner, thereby maintaining the good filtering performance of the filter element 91 and extending the service life of the filter element 91. The upper end of the inner wall of the filter cartridge dust removal tank 1 is connected to the mounting seat 10. An activated carbon filter layer 11 is connected to the inner middle part of the mounting seat 10. The gas after preliminary filtration continues to rise and is further adsorbed and purified by the activated carbon filter layer 11 located in the inner middle part of the mounting seat 10 at the upper end of the inner wall of the filter cartridge dust removal tank 1. Finally, the purified gas is discharged from the outlet pipe 3. The air inlet pipe 2 is located at the bottom of multiple filter elements 91, and the cone 4 is arranged at the lower inner side of the air inlet pipe 2. The air outlet pipe 3 is located on the upper end side of the activated carbon filter layer 11. A sealing top cover 7 is installed on the top of the filter cartridge dust removal tank 1, which is convenient for opening the filter cartridge dust removal tank 1 to maintain and replace the activated carbon filter layer 11.

[0021] Reference Figure 1-Figure 3The bottom of the ash collecting bucket 5 is evenly fixed with multiple universal wheels 6, and the upper end of the ash collecting bucket 5 is detachably connected to the bottom of the cone 4 through a pipe clamp. The ash collecting bucket 5 is detachably connected to the bottom of the cone 4 through the pipe clamp, which is convenient for collecting dust and improves the practicality and maintenance convenience of the equipment. A plurality of connecting screws 12 are evenly penetrated at the bottom of the sealing top cover 7, and the bottoms of the plurality of connecting screws 12 are threadedly connected to the top of the filter cartridge dust removal tank 1, which ensures the sealing of the equipment and reduces the possibility of leakage of dust-laden gas, which helps to improve the dust removal and purification effect of the equipment. Multiple connecting screws 12 are evenly installed on the upper end side of the filter cartridge dust removal pipe. The inner sides of the plurality of fixing plates 13 are rotatably connected to an adjusting rod 14, the upper ends of the adjusting rods 14 are fixedly connected to a threaded sleeve 15, the top of the sealing top cover 7 is rotatably connected to a threaded rod 16, the upper ends of the threaded rods 16 are fixedly connected to a handwheel 17, the surface of the threaded rod 16 is threadedly connected to the inside of the threaded sleeve 15, when the sealing top cover 7 needs to be opened, the handwheel 17 is rotated, and the handwheel 17 drives the threaded rod 16 to rotate. Since the surface of the threaded rod 16 is threadedly connected to the inside of the threaded sleeve 15, the rotation of the threaded rod 16 will cause the sealing top cover 7 to rise, thereby opening the equipment for maintenance.

[0022] The implementation principle of the pulse vibration dust cleaning device of a filter element in the embodiment of the present application is as follows: when in use, first, the dust-laden gas enters the filter cartridge dust removal tank 1 from the air inlet pipe 2. In the filter cartridge dust removal tank 1, the gas is first preliminarily filtered by the filter element 91. At this time, part of the dust falls into the cone 4 below through the filter element 91 under the action of gravity, and is finally collected in the dust collecting bucket 5. Then, the gas preliminarily filtered by the filter element 91 continues to rise and is further adsorbed and purified by the activated carbon filter layer 11. The activated carbon filter layer 11 can effectively adsorb harmful substances such as dioxins, mercury vapor and SO2, further improving the gas purification effect. When it is necessary to clean the filter element 91, the pulse solenoid valve 9 3 starts working, and compressed air passes through each pulse valve in sequence in a very short time, and is sprayed to the filter element 91 through the nozzle of the blowing pipe 94. Under the action of the reverse airflow, the filter element 91 vibrates, and the dust attached to the outer surface of the filter element 91 is peeled off and falls into the dust collecting device composed of the cone 4 and the dust collecting bucket 5. This pulse vibration cleaning method can timely and effectively remove the dust on the surface of the filter element 91, maintain the good filtering performance of the filter element 91, and extend the service life of the filter element 91. When maintaining the equipment, the hand wheel 17 can be turned to rotate the threaded rod 16. Since the threaded rod 16 is threadedly connected to the threaded sleeve 15, it can drive the sealing top cover 7 to rise, thereby facilitating maintenance operations inside the equipment.
