Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic precipitators, and in particular to the technical field of cathode wires. Background Technology

[0002] The core of an electrostatic precipitator is to charge dust particles with a high-voltage electrostatic field and adsorb them onto the electrodes, thereby reducing the emission of air pollutants. Its working principle is based on four key stages: gas ionization, dust charging, dust migration, and dust deposition. The discharge of the barbed wire can charge the dust, while the accumulation of dust on the barbed wire and the frequent shedding of the barbs are the main reasons for reducing the dust charging.

[0003] When the barbed wire adopts an integrated stamping method for the barbs and the barbs, although it can prevent the barbs from falling off, it will greatly increase the production cost. Moreover, the integrated stamping method will increase the contact area between the barbs and dust, making the barbed wire more prone to dust accumulation. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a steel pipe type barbed wire that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a steel pipe type barbed wire, including a round tube and discharge barbs. The round tube is provided with a plurality of discharge barbs along its length. The discharge barbs are provided with discharge ends at both ends. The middle part of the discharge barbs is provided with a bent plate that matches the round tube. The bent plate is installed to match the outer surface of the round tube. The round tube has connecting ends at both ends, and the connecting ends are connected to the cathode frame.

[0006] Preferably, the inside of the circular tube is hollow, and the connecting end is a flat-head structure formed by rolling the circular tube. A bolt hole is opened on the axis of the connecting end, and the bolt hole is fixedly connected to the cathode frame by bolts.

[0007] Preferably, the discharge spikes are arranged in a parallel array.

[0008] Preferably, the discharge ends of the discharge spikes have a centrally symmetrical structure.

[0009] Preferably, the head of the discharge end is provided with a U-shaped groove, and the two sides of the U-shaped groove are respectively provided with arc-shaped tips. The two arc-shaped tips are bent to the sides to form a Y-shaped structure, and the width of the arc-shaped tips gradually decreases along the direction away from the circular tube.

[0010] Preferably, the two ends of the bent plate are welded to the round pipe through a single-sided trumpet-shaped weld.

[0011] The beneficial effects of this utility model are as follows: This utility model uses a round steel pipe as the body of the barbed wire. The discharge barbs are first bent into an arc shape in the middle and then clamped onto the steel pipe. Then, the discharge barbs and the steel pipe are connected into a whole by welding. Compared with the prior art, the barbed wire tube is easy to manufacture, the surface is arc-shaped and not easy to accumulate dust, the barbs are easy to install, and they are fixed by buckles and welding, so the barbs are not easy to fall off.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description
