Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, and more specifically, it relates to a dust collector for smoke and dust. Background Technology

[0002] A baghouse dust collector is a device that uses filter bags with filter material to separate dust from flue gas. The flue gas carrying dust passes through the filter bags, and some dust falls into the ash hopper below, while some dust remains on the surface of the filter bags. Then, through periodic backflushing, the dust remaining on the surface of the filter bags is shaken off into the ash hopper below. This cycle is repeated to continuously filter the flue gas. In existing baghouse dust collectors, in order to ensure that the filter bags remain stretched to maintain the maximum filtration area, a frame is inserted inside the filter bags. However, the frame itself will block part of the surface of the filter bags, reducing the effective filtration area of ​​the filter bag surface.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dust collector for smoke and dust.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dust collector for smoke and dust, comprising a housing and a plurality of filter bags, wherein the top end of the filter bag is snapped onto the top surface of the housing, a fixing ring is fixedly connected to the bottom surface of the filter bag, a plurality of fixing plates are detachably connected to the inner side wall of the housing, the fixing ring is detachably connected to the fixing plate, and a through groove is provided on the top surface of the fixing plate.

[0006] The present invention is further configured such that: a plurality of magnetic rings are fixedly connected to the top surface of the fixing plate, and the top surface of the magnetic rings is attracted to the bottom surface of the fixing ring.

[0007] The present invention is further configured such that: a connecting rib is fixedly connected to the top surface of the fixing plate, and the connecting rib connects to the adjacent magnetic ring.

[0008] The present invention is further configured such that: a slide rail is fixedly connected to the side wall of the housing, the fixing plate is slidably connected to the slide rail, and a door panel is detachably connected to the side wall of the housing, the width of the door panel being greater than the length of the fixing plate.

[0009] The present invention is further configured such that: a plurality of card frames are slidably connected on the slide rail, the card frames and the fixing plate are alternately arranged on the slide rail, and the side wall of the card frame abuts against the side wall of the fixing plate.

[0010] The present invention is further configured such that the filter bag is made of PTFE material.

[0011] In summary, this utility model has the following beneficial effects: when the fixing plate is connected to the fixing ring, the filter bag is tightened, thereby keeping the filter bag in an extended state, avoiding the need to install a skeleton, ensuring the effective filtration area of ​​the filter bag surface, and the PTFE material has good tensile strength, thus ensuring the service life of the filter bag in the stretched state. The through groove penetrates the fixing plate, ensuring that the flue gas passes smoothly through the fixing plate. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Example: A dust collector using a filter bag, such as... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a housing 1 and several filter bags 2. The top of the filter bag 2 is snapped onto the top surface of the housing 1. A fixing ring 3 is fixedly connected to the bottom surface of the filter bag 2. Several fixing plates 4 are detachably connected to the inner side wall of the housing 1. The fixing ring 3 and the fixing plate 4 are detachably connected. A through groove 5 is provided through the top surface of the fixing plate 4. The filter bag 2 is made of PTFE material.

[0018] Specifically, an air inlet is provided on the side wall of the housing 1. A guide plate is provided inside the cavity of the housing 1, located on the side where the filter bags 2 are located. The dust-laden gas entering from the air inlet is guided by the guide plate and flows upward into the chamber where the filter bags 2 are located. The upper part of the housing 1 is a clean air chamber, which is connected to the outside through a gate. Several round holes are provided on the top surface of the housing 1, and a filter bag 2 should be installed in any round hole. The filter bag 2 is connected to the clean air chamber through the round hole. Larger dust particles in the dust-laden gas fall directly into the dust hopper at the bottom of the housing 1, while smaller dust particles collide with the surface of the filter bags 2 with the airflow. The dust particles are blocked by the filter bags 2 and fall. The gas passes through the filter bags 2 and reaches the clean air chamber for discharge. A backflush pump is provided on one side of the housing 1, which is connected to the clean air chamber. When the filter bags... When there is a lot of dust attached to filter bag 2, the gate is closed, and the airflow generated by the backwash pump rushes into filter bag 2. Filter bag 2 bulges and shakes, causing the dust to fall off. The top of filter bag 2 is covered with a retaining ring, which is locked onto the side wall of the round hole. The bottom surface of filter bag 2 is bonded with a fixing ring 3. When the fixing plate 4 is connected to the fixing ring 3, filter bag 2 is straightened, so as to keep filter bag 2 in an extended state, avoiding the need to install a frame and ensuring the effective filtration area of ​​filter bag 2. Filter bag 2 is not kept completely taut. Combined with the slight elasticity of filter bag 2 itself, the shaking amplitude of filter bag 2 during backwashing is ensured. PTFE material has good tensile strength, thus ensuring the service life of filter bag 2 in the stretched state. The through groove 5 penetrates the fixing plate 4 to ensure that the flue gas passes smoothly through the fixing plate 4.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, several magnetic rings 6 are fixedly connected to the top surface of the fixing plate 4. The top surface of the magnetic rings 6 is attracted to the bottom surface of the fixing ring 3. Connecting ribs 7 are fixedly connected to the top surface of the fixing plate 4. The connecting ribs 7 connect adjacent magnetic rings 6. Specifically, eight columns are integrally formed on the top surface of any fixing plate 4. The columns and connecting ribs 7 are integrally formed. The magnetic rings 6 consist of an outer covering layer and a magnet located inside the covering layer. The covering layer and connecting ribs 7 are integrally formed. The fixing ring 3 consists of a plastic layer and an iron ring located inside the plastic layer. The magnetic rings 6 and the fixing ring 3 are attracted by magnetic force. The connecting ribs 7 improve the connection strength between the magnetic rings 6 and ensure the service life of the base plate and the magnetic rings 6.

[0020] A slide rail 8 is fixedly connected to the side wall of the housing 1. A fixing plate 4 is slidably connected to the slide rail 8. A door panel 9 is detachably connected to the side wall of the housing 1. The width of the door panel 9 is greater than the length of the fixing plate 4. Several clip frames 10 are slidably connected to the slide rail 8. The clip frames 10 and the fixing plates 4 are alternately arranged on the slide rail 8. The side wall of the clip frame 10 abuts against the side wall of the fixing plate 4. Specifically, several partitions are welded inside the housing 1. The cover plate divides the inner cavity of the housing 1 into several independent cavities. Two fixing plates 4 and three clip frames 10 should be installed in any independent cavity. Any fixing plate 4 is located between two adjacent clip frames 10. Adjacent door panels 9 and door panels 9 and housing 1 are all connected by bolts. When it is necessary to remove the fixing plate 4 and filter bag 2, the corresponding door panel 9 is removed, and the clip frames 10 and fixing plates 4 are slid out and removed. The fixing plate 4 is limited by sliding and abutting, so that maintenance personnel do not need to enter the housing 1.
