[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] To facilitate understanding of this embodiment, the following is a brief introduction to the technologies involved in this application.

[0030] Spot welding refers to a welding method that uses a cylindrical electrode to form a weld between the contact surfaces of two overlapping workpieces. During spot welding, pressure is first applied to make the workpieces in close contact, and then current is turned on. The contact between the workpieces melts under the action of resistance heat, and a weld is formed after cooling.

[0031] After introducing the technical terms involved in this application, the application scenarios and design concepts of the embodiments of this application are briefly introduced.

[0032] The working principle of the electrostatic precipitator is to use a high-voltage direct current non-uniform electric field to ionize the gas molecules in the flue gas, generating a large number of electrons and ions, which move toward the two poles under the action of the electric field force. During the movement, they encounter dust particles in the airflow and charge them. The charged dust is separated from the airflow under the action of the electric field force and moves toward the plates or pole lines with opposite polarity. When the charged dust reaches the plates or pole lines, it is adsorbed on the plates or pole lines by electrostatic force, and the dust falls into the ash hopper through the vibration device, thereby purifying the flue gas.

[0033] In the prior art, the method of increasing the area of ​​the dust collecting plate is adopted, which leads to high production cost and poor structural stability.

[0034] Based on this, an embodiment of the present application provides an N-type airflow uniform distribution dust collecting plate, an electrostatic precipitator and an electrostatic precipitator system.

[0036] The present application provides an N-type airflow uniform distribution dust collecting plate, which includes: an N-type plate body 10, a mesh 20 and a reinforcement plate 30.

[0037] Combination Figure 1 , Figure 2 As shown, the N-type plate body 10 includes a first plate body 11, a second plate body 12 and a third plate body 13 which are connected in sequence; one end of the first plate body 11 and the third plate body 13 respectively has an outer edge 14 extending outward.

[0038] The mesh 20 is formed on the N-shaped plate 10 to conduct airflow.

[0039] The reinforcement plate 30 is disposed on the outer edge 14 for reinforcing the outer edge 14 .

[0040] The N-type plate body 10 provided in the present application has a diamond-shaped mesh 20. When the flue gas containing dust passes through the N-type airflow uniform distribution dust collecting plate, the dust will undergo multiple deflections and multiple collisions with the N-type airflow uniform distribution dust collecting plate. According to the particle collision theory, large dust particles are adsorbed and captured, thereby improving the dust removal effect. In addition, the first plate body 11 and the third plate body 13 of the N-type plate body 10 have an outer edge 14 extending outward, and a reinforcement plate 30 is provided on the outer edge 14 for reinforcement, so as to improve the overall structural strength of the N-type mesh plate, thereby improving its reliability.

[0041] Among them, the first plate body 11, the second plate body 12 and the third plate body 13 are all flat plates, the first plate body 11 and the third plate body 13 are respectively connected to the two ends of the second plate body 12, and there is an acute angle between the first plate body 11 and the second plate body 12, and there is an acute angle between the second plate body 12 and the third plate body 13, thereby forming an N-type structure. The specific connection method can be connected and fixed by a more common connecting piece, or it can be connected by a mortise and tenon structure, and the specific connection method is not limited here.

[0042] In this embodiment, the N-type plate body 10 is a plate body with a mesh 20 formed by a metal plate through special mechanical stamping and cold drawing. The reinforcement plate 30 is folded along the outer edge to form a U-shaped structure, and a connection port is opened on the reinforcement plate 30, and the U-shaped reinforcement plate 30 is wrapped around the outer edge and connected and fixed by spot welding. In this embodiment, the reinforcement plate 30 is made of 430 stainless steel and has a thickness of 1 mm. Through the above reinforcement method, the strength of the N-type airflow uniform distribution dust collecting plate can be improved, thereby improving the reliability of the N-type airflow uniform distribution dust collecting plate.

[0044] The connection of the N-type plate body is reinforced by strengthening the keel group to improve the overall strength of the N-type plate body, thereby improving the reliability of the N-type airflow uniform distribution dust collecting plate.

[0045] Since the first plate 11, the second plate 12 and the third plate 13 constituting the N-type plate are all plates with a certain thickness, the connection between two adjacent plates is reinforced by the reinforcing keel 40 to improve the structural stability and overall lightness. In order to ensure effective reinforcement, the connection between two adjacent plates is generally covered from the outside. At this time, one reinforcing keel group includes one reinforcing keel 40.

[0046] Furthermore, a reinforcing keel 40 is also provided on the inner side of the connection between the two plates, so that the reinforcing keel group includes two reinforcing keels 40, the two reinforcing keels 40 are coaxial and each reinforcing keel 40 is provided with a connecting hole, and the two reinforcing keels 40 are welded to both sides of the connection through the connecting holes.

[0047] The connection between two adjacent plates is consolidated and strengthened from the inside and outside of the head to improve the structural stability of the N-type plate.

[0048] In combination with the first aspect, the mesh 20 is one of a triangular, rectangular, rhombus, circular, and polygonal structure.

[0049] The shape of the mesh 20 on the N-type plate can be arbitrary and can be selected and processed according to actual use requirements, and is not limited here.

According to the particle collision theory, large dust particles are adsorbed and captured; and the N-type airflow uniform distribution dust collecting plates have a deflecting effect on the flue gas running in the direction perpendicular to the airflow, so that the airflow distribution entering the electric field is more reasonable and uniform; thereby achieving a more efficient dust removal effect. In addition, it also has the advantages of compact structure, easy installation and maintenance, etc.

[0055] In combination with the second aspect, the electrostatic precipitator further includes: a hanging portion, which is located in the precipitator body, and the N-type airflow uniform distribution dust collecting plate is connected to the hanging portion through a connecting piece.
