DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] As mentioned in the background technology, in industrial production, especially in mining, cement manufacturing and chemical industries, dust emission is a major environmental problem. Although traditional dust collection technologies such as bag dust collectors and electrostatic dust collectors have solved the dust pollution problem to a certain extent, they still have disadvantages such as low efficiency, high maintenance cost and large footprint. Therefore, the development of an efficient, economical and small-footprint dust collection system has become an urgent need in the industry.

[0034] In order to improve the above-mentioned problems, the present application proposes a radial dust collecting system, which can effectively collect most of the dust and improve the dust removal efficiency by setting a dust collecting plate in the shape of a rectangular frame at the outlet end of the electric field of the electrostatic precipitator and tilting rectangular dust collecting sheets. Since the dust collecting sheets are tilted, the dust is subjected to the geometric multiplication effect of the Coulomb force when passing through the dust collecting plate, so that it is easier to be adsorbed on the dust collecting sheets and the rectangular frame. The system adopts a combination design of a rectangular frame and a rectangular dust collecting sheet, which has a compact structure, a small footprint, and is easy to install and maintain. The dust attached to the dust collecting sheets and the rectangular frame can be vibrated by the vibration of the vibrator fixed on the top, which is convenient for cleaning and treatment. The radial dust collecting system proposed in the present application has the advantages of efficient capture, increased Coulomb force, compact structure, easy cleaning, energy saving and environmental protection, and a wide range of applications. It is a dust removal equipment with broad application prospects.

[0036] A plurality of connecting columns 1 are arranged in parallel and on the same plane at intervals, and the bottom of the connecting column 1 is fixedly connected to the inner bottom wall of the electrostatic precipitator;

[0038] A rapper 3 is vertically arranged, and a vibrating end of the rapper 3 penetrates the fixed plate 2 and extends downward;

[0039] The connecting plate 4 is arranged at the bottom of the fixing plate 2, and the connecting plate 4 is detachably connected to the fixing plate 2, and the bottom vibration end of the rapper 3 is fixedly connected to the top of the connecting plate 4;

[0040] The dust collecting plate 5 is arranged at the bottom of the connecting plate 4, and the dust collecting plate 5 corresponds to the electric field outlet end. The dust collecting plate 5 is used to collect dust flowing out of the electric field outlet end. The dust collecting plate 5 includes:

[0041] Frame assembly, the top of the frame assembly is fixedly connected to the bottom of the connecting plate 4, and the bottom of the frame assembly is fixedly connected to the connecting column 1 through the positioning pin 7;

[0042] Dust collecting sheets 6 are provided in plurality, and the plurality of dust collecting sheets 6 are vertically and obliquely arranged in the frame assembly, and the side walls of the dust collecting sheets 6 are fixedly connected to the inner walls of the frame assembly.

[0043] It should be understood that the connecting column 1 is used to support the entire dust collecting plate 5, the fixing plate 2, the rapper 3, and the connecting plate 4, and the vibration is transmitted to the dust collecting plate 5 through the rapper 3, so that the dust on the dust collecting plate 5 falls off.

[0044] In some specific embodiments, the plurality of connecting columns 1 have the same length, and the tops thereof are located on the same straight line, and the dust collecting plates 5 are placed between the plurality of connecting columns 1 .

[0045] In some specific embodiments, a plurality of rappers 3 are arranged along the two ends of the fixing plate 2 .

[0046] In some specific embodiments, the axial cross-section of the connecting plate 4 is rectangular, and two ends of the connecting plate 4 are arranged corresponding to the length direction of the fixing plate 2 .

[0047] In some specific embodiments, the stud bolts 8 pass through the fixing plate 2 and the connecting plate 4 in sequence to fix the connecting plate 4 to the bottom of the fixing plate 2 , and a plurality of stud bolts 8 are arranged along both ends of the fixing plate 2 .

[0048] In some specific embodiments, the frame assembly includes:

[0049] There are two support plates 9 symmetrically arranged, the tops of the two support plates 9 are fixedly connected to the bottom of the connecting plate 4, and the side of the support plate 9 close to the connecting column 1 is fixedly connected to the connecting column 1 through the positioning pin 7;

[0050] There are multiple limit bars 10 spaced apart along the height direction of both sides of the two support plates 9, and both ends of the multiple limit bars 10 are respectively fixedly connected to the two support plates 9, the multiple limit bars 10 and the two support plates 9 form a rectangular frame, and the multiple dust collecting sheets 6 are vertically and obliquely arranged in the rectangular frame, and the side walls of the multiple dust collecting sheets 6 are fixedly connected to the limit bars 10.

[0051] It should be understood that when the smoke and dust at the outlet of the electric field passes through the rectangular frame, the dust adheres to the limit strip 10 under the action of the vertically inclined limit strip 10. The vertically inclined limit strip 10 adjusts the direction and speed of the airflow to make the flow velocity of the smoke in the electric field more uniform, and can effectively disperse the high-speed airflow entering the electric field, reduce the direct impact of the airflow on a certain area, thereby avoiding the re-suspension of dust particles caused by local high-speed airflow. By optimizing the direction of the airflow, the limit strip 10 helps to reduce eddy currents and dead zones in the electric field. The limit strip breaks the large-scale turbulence to form small-scale turbulence and weakens the turbulence intensity within a short distance, which helps to improve the overall dust removal efficiency. The vertically inclined limit strip 10 disperses the airflow, reduces the airflow velocity in the local area, reduces the scouring effect on the dust in the anode plate and the ash hopper, thereby avoiding the occurrence of secondary dust. Since the dust particle size at the outlet is finer and the adhesion is stronger, the use of a limit strip 10 with a larger angle can further promote the adhesion of dust to the surface of the structure to prevent it from being carried away by the airflow.

[0052] In some specific embodiments, a first connecting plate 11 is fixedly connected to the top of the two support plates 9 . The length of the first connecting plate 11 is the same as the length between the two support plates 9 . The first connecting plate 11 is fixedly connected to the connecting plate 4 through a plurality of equidistant and vertically arranged connecting strips 12 .

[0053] In some specific embodiments, a plurality of dust collecting plates 5 and first connecting plates 11 are arranged along the length direction of the connecting plate 4 , and the bottoms of the plurality of dust collecting plates 5 are fixedly connected by a positioning plate 13 .

[0054] It should be understood that the plurality of dust collecting plates 5 are fixedly connected together by a positioning plate 13 arranged at the bottom, and the dust collecting plates 5 located on both sides are fixedly connected to the connecting column 1 by a positioning pin 7 near the connecting column 1 .
