[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] As described in the background technology, an electrostatic precipitator is a commonly used industrial dust treatment equipment. It generates a strong electric field to charge the dust particles in the dust-laden gas, and then under the action of the electric field, the charged dust particles move toward the collecting electrode and settle, thereby achieving the purpose of dust removal. However, traditional electrostatic precipitators have some problems, such as low dust collection efficiency, high energy consumption, and poor collection effect on tiny particles.
[0028] In order to improve the above problems, the present application proposes a high-efficiency radial flow porous dust collection auxiliary dust collection device. The radial flow porous plate is installed at the outlet end of the electric field anode plate and is welded to the windproof hook of the anode plate at the end of the anode row, which can significantly improve the dust charging performance. The electric field has the same pole distance of 400, and the width of the radial flow porous dust collection device is 240mm. The middle 160mm near the cathode line is not installed with the radial flow porous plate dust collection device. Therefore, the flue gas flow in this area is large, and more flue gas dust passes through the area with high negative ion concentration. Near the discharge stage, the charge is more complete, and the fully charged dust is easier to be captured by the anode dust collector. The negative ion dust after the last cathode line and the anode plate high voltage ionization, before being collected by the anode plate, runs out of the electric field. Some dust is collected by the runoff deep porous plate trough device installed at the tail. The tail runoff porous plate dust collector also changes the uniformity of the airflow distribution at the end of the electric field, and can also increase the ability of the last stage anode plate to collect more dust, thereby improving the dust collection efficiency of the electric field at this level.
[0029] Reduce secondary dust from vibration. Since the opening rate of the radial flow porous plate dust collector of the present application is about 50%, the secondary dust generated by the mechanical vibration of the anode plate can be collected in the porous groove frame at the tail of the anode plate, thereby achieving the purpose of reducing secondary dust;
[0030] Increase the dust collection area. The extended length of the runoff deep porous plate dust collector of the present application is about 590 mm, which is equivalent to adding a dust collection area of an anode plate;
[0031] The structure is simple and does not require an additional vibrating device. The radial flow porous plate dust collecting device of the present application is welded to the windproof hook of the end anode plate of the anode row, forming a whole with the anode plate and sharing the vibrating device of the anode row, so there is no need to install an additional vibrating device.
[0032] See also Figure 1-4 As shown, according to an embodiment of the present application, a high-efficiency radial flow porous dust collection auxiliary dust collection device comprises:
[0033] The radial flow porous plate 1 is used to be arranged at the outlet end of the electric field anode plate in the electrostatic precipitator. A plurality of through holes 2 are arranged on the radial flow porous plate 1. Both ends of the radial flow porous plate 1 are bent inward to form a porous plate groove 3.
[0034] A reinforcing rib 4, one end of which is fixedly connected to the notch end of the porous plate slot 3, and the other end of which is used to be fixedly connected to the anode plate;
[0035] Connecting rib plates 5, one reinforcing rib 4 corresponds to two connecting rib plates 5, both ends of the connecting rib plates 5 are respectively fixedly connected to the anode plate and the two ends of the opening of the porous plate slot 3, and the two connecting rib plates 5 are used to fix the porous plate slot 3 and the anode plate.
[0036] It should be understood that the radial flow porous plate 1 is installed at the outlet end of the electric field anode plate, and is welded to the windproof hook of the end anode plate of the anode row. The length along the flue gas flow direction is about 250mm. A porous plate groove with a thickness of 2mm and an opening installed at the end is about 240mm wide, with an opening rate of 50% and an aperture of 30mm. The electric field has the same pole distance of 400, and the width of the radial flow porous dust collector is 240mm. The middle 160mm near the cathode line is not installed with the radial flow porous plate dust collector. Therefore, the flue gas flow in this area is large, and more flue gas dust passes through the discharge level with high negative ion concentration, and the charge is more sufficient. The fully charged dust is easier to be captured by the anode dust collecting electrode. The porous plate groove and the radial flow porous plate are fixed by reinforcing ribs, and the radial flow porous plate dust collector is welded to the windproof hook of the end anode plate of the anode row, forming a whole with the anode plate, and sharing the vibration device of the anode row, so there is no need to install a vibration device additionally, and the reinforcing ribs can improve the efficiency of vibration transmission.
[0037] See also Figure 4 As shown, the anode plates on both sides of the electrostatic precipitator and the 1 / 2 high-efficiency radial flow porous dust collection auxiliary dust collection device can not only ensure the dust removal efficiency of the device, but also improve the space occupancy rate of the device in the electrostatic precipitator.
[0038] In some specific embodiments, the reinforcing ribs 4 are arranged perpendicular to the inner bottom wall of the porous plate groove 3 .
[0039] In some specific embodiments, a plurality of reinforcing ribs 4 are provided along the two ends of the porous plate slot 3 corresponding to the plurality of anode plates.
[0040] In some specific embodiments, the reinforcing rib 4 and the connecting rib plate 5 are welded to the windproof hook of the anode plate at one end close to the anode plate.
[0041] In some specific embodiments, a first threaded hole 6 is provided at one end of the reinforcing rib 4 near the porous plate groove 3, and a second threaded hole 7 matching the first threaded hole 6 is provided at the bottom of the porous plate groove 3. The reinforcing rib 4 near one end of the porous plate groove 3 is fixedly connected to the porous plate groove 3 by bolts passing through the first threaded hole 6 and the second threaded hole 7 in sequence.
[0042] In some specific embodiments, a third threaded hole 8 is provided at one end of the connecting rib plate 5 close to the porous plate groove 3, and fourth threaded holes 9 are provided on both side ends of the porous plate groove 3 corresponding to the third threaded hole 8. The connecting rib plate 5 is fixedly connected to both side ends of the porous plate groove 3 by bolts passing through the third threaded hole 8 and the fourth threaded hole 9 in sequence.
[0043] In some specific embodiments, a plurality of second threaded holes 7 and fourth threaded holes 9 are correspondingly arranged along the two end directions of the porous plate slot 3 .
[0044] In some specific embodiments, the bolts are passed through the first threaded hole 6 , the second threaded hole 7 , the third threaded hole 8 , and the fourth threaded hole 9 and then tightened before welding.
[0045] It should be understood that all bolts and nuts need to be welded after tightening. Welding can effectively prevent bolts and nuts from loosening on their own during long-term use. The welded bolt and nut connection has higher tensile strength and shear strength than ordinary bolt connections. This is especially important for structures that bear heavy or dynamic loads. Welding can ensure that these components remain fixed throughout their service life. Using welding to handle bolt and nut connections can save time and cost while maintaining consistent quality and reliability.
[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
