Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to an ultra-clean electrostatic precipitator-baghouse composite dust collector. Background Technology

[0002] Currently, industrial dust removal mainly employs two types of technologies: electrostatic precipitators, which use a high-voltage electric field to charge dust particles and adsorb them onto the plates, but suffer from low collection efficiency for fine particulate matter such as PM2.5 and serious secondary dust generation; and baghouse dust collectors, which rely on filter bags to physically intercept dust. Although they have a high collection efficiency for fine particulate matter, they have high operating resistance, the filter bags are prone to clogging and have a short lifespan, and they are not suitable for high-temperature flue gas. Utility Model Content

[0003] The purpose of this invention is to provide an ultra-clean electrostatic precipitator / bag filter composite dust collector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ultra-clean electrostatic precipitator / bag filter composite dust collector, comprising a shell, the upper end of which is located at the flue gas inlet. A flexible hose and a guide plate are respectively connected to the outer and inner walls of the shell. Both the flexible hose and the guide plate are located at the flue gas inlet, and they cooperate to transport the flue gas into the shell and guide the flue gas during transport. A filter bag is fixedly connected to the lower end of the guide plate via bolts or a flange. A pulse jet pipe is fixedly connected to the side end of the shell. An adjusting component and a limiting component are fixedly connected to the middle of the guide plate. The adjusting component is threadedly connected to a... The threaded column has a limiting head in the middle of the limiting member. The adjusting member and the limiting member cooperate with each other. When the position and height of the limiting head change, the limiting head can be switched from a rotating state to a fixed state. A driving column is fixedly connected to the upper end of the threaded column. An electrode column for charging passing dust is fixedly connected to the upper end of the driving column. A connecting head is fixedly connected to the upper end of the electrode column. A connecting column is fixedly connected to the lower end of the limiting head. An installation cylinder is fixedly connected to the lower end of the connecting column. At least two electrode plates are fixedly connected to the middle of the installation cylinder. The electrode plates are used to attract charged dust.

[0005] Preferably, the sidewall of the guide plate is inclined at an angle of 10 degrees, the guide plate is a mesh structure, and the pulse jet pipe and the guide plate are at the same height.

[0006] Preferably, the adjusting component includes an adjusting ring and an adjusting plate, with both ends of the adjusting plate fixedly connected to the outer wall of the adjusting ring and the inner wall of the guide plate, respectively, and the threaded column being threadedly connected to the inner wall of the adjusting ring.

[0007] Preferably, the limiting component includes a limiting ring and a limiting plate, with both ends of the limiting plate fixedly connected to the outer wall of the limiting ring and the inner wall of the guide plate, respectively, and both ends of the limiting head penetrating through the limiting ring.

[0008] Preferably, the diameter of the limiting head gradually decreases from top to bottom, and a rotating head is fixedly connected to the upper end of the limiting head. The rotating head has a spherical structure, and the upper end of the rotating head is cut to form a plane. The rotating head is embedded in the lower end of the threaded column and can rotate relative to the threaded column.

[0009] Preferably, the electrode post is energized to form a high-voltage electric field, which charges the passing dust, and the connector is located at the hose portion.

[0010] Preferably, a conductive post is fixedly connected inside the mounting cylinder, the upper half of the electrode plate is a horizontal structure, the upper half of the electrode plate penetrates through the mounting cylinder, the lower half of the electrode plate is an arc-shaped structure, and the electrode plate and the electrode post form opposite electrodes when energized.

[0011] Compared with the prior art, the beneficial effects of this utility model are: it combines the advantages of electrostatic precipitators and bag filters. When dust passes through the electric field formed by the electrode column and becomes charged, it is attracted and fixed by the electrode plate with the opposite charge when it reaches the electrode plate. When the power is cut off, the dust will naturally settle into the filter bag, without causing secondary dust generation. At the same time, it ensures the collection efficiency of fine particulate matter and avoids the problem of easy clogging of the filter bag. Attached Figure Description

[0017] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an ultra-clean electrostatic precipitator / bag filter composite dust collector, including a shell 1. The upper end of the shell 1 is located at the flue gas inlet. A flexible hose 7 and a guide plate 2 are respectively connected to the outer and inner walls of the shell 1. Both the flexible hose 7 and the guide plate 2 are located at the flue gas inlet and cooperate to transport the flue gas into the shell 1 and guide the flue gas during transport. A filter bag 3 is fixedly connected to the lower end of the guide plate 2 by bolts or a flange. A pulse jet pipe 12 is fixedly connected to the side end of the shell 1. An adjusting component 15 and a limiting component 16 are fixedly connected in the middle of the guide plate 2. A threaded post 14 is threadedly connected to the middle of the adjusting component 15, and a limiting head 8 is provided in the middle of the limiting component 16. The adjusting component 15 and the limiting component 16... The components work together to switch between rotating and fixed states when the position and height of the limiting head 8 change. A drive column 4 is fixedly connected to the upper end of the threaded column 14. An electrode column 5 for charging passing dust is fixedly connected to the upper end of the drive column 4. A connector 6 is fixedly connected to the upper end of the electrode column 5. A connecting column 9 is fixedly connected to the lower end of the limiting head 8. An installation cylinder 10 is fixedly connected to the lower end of the connecting column 9. At least two electrode plates 11 are fixedly connected in the middle of the installation cylinder 10. The electrode plates 11 are used to adsorb charged dust. Both the electrode column 5 and the electrode plates 11 are energized and form opposite electrodes. When the flue gas enters the outer casing 1 through the hose 7, it passes through the electrode column 5 and the electrode plates 11 in sequence.

[0019] The side wall of the guide plate 2 is inclined at an angle of 30 degrees. The guide plate 2 has a mesh structure. The pulse jet pipe 12 and the guide plate 2 are located at the same height. The guide plate 2 can guide the incoming flue gas. When encountering high-temperature gas, the pulse jet pipe 12 can spray cooling gas to cool down the high-temperature gas, thereby avoiding damage to the filter bag by the high-temperature gas and ensuring an extended service life of the filter bag.

[0020] The adjusting component 15 includes an adjusting ring and an adjusting plate. The two ends of the adjusting plate are fixedly connected to the outer wall of the adjusting ring and the inner wall of the guide plate 2, respectively. The threaded post 14 is threadedly connected to the inner wall of the adjusting ring. The limiting component 16 includes a limiting ring and a limiting plate. The two ends of the limiting plate are fixedly connected to the outer wall of the limiting ring and the inner wall of the guide plate 2, respectively. The two ends of the limiting head 8 pass through the limiting ring. The diameter of the limiting head 8 gradually decreases from top to bottom. A rotating head 13 is fixedly connected to the upper end of the limiting head 8. The rotating head 13 has a spherical structure, and its upper end is cut to form a plane. The rotating head 13 is embedded in the lower end of the threaded post 14 and can rotate relative to the threaded post 14. The electrode post 5 is energized to form a high-voltage electric field, which then causes the powder to pass through... Dust-charged, connector 6 is located at hose 7. When hose 7 is pressed and connector 6 is rotated, connector 6 can drive threaded post 14 to rotate via drive post 9, thereby adjusting the height of limit head 8. When the side wall of limit head 8 and the inner side wall of limit ring abut against each other, limit head 8 is limited and fixed. When limit head 8 is not abutting against the inner side wall of limit ring, rotating head 13 can rotate with threaded post 14. When gas enters the outer shell 1, it can cause mounting cylinder 10 and electrode plate 11 to rotate, causing limit head 8 to collide with limit ring. At this time, electrode plate 11 will vibrate, thereby shaking off the dust attached to electrode plate 11, ensuring subsequent dust capture.

[0021] The mounting cylinder 10 has a fixed internal connection to a conductive post 17. The upper half of the electrode plate 11 is horizontal and extends through the mounting cylinder 10. The lower half of the electrode plate 11 is arc-shaped. When the electrode plate 11 is energized, it forms an opposite electrode with the electrode post 5. This allows dust to carry a charge after passing through the electric field formed by the electrode post 5. When the dust reaches the electrode plate 11, the charge carried by the dust is opposite to that of the electrode plate 11, thus allowing the dust to be adsorbed onto the electrode plate for efficient dust capture.

[0022] Although embodiments of the present invention have been shown and described, it should be emphasized that the above description is merely an introduction and description of the usage of the embodiments of the present invention, and is not intended to limit the present invention in any way. Those skilled in the art will understand that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
