Problems solved by technology

At present, two types of polar lines are commonly used in wet electrostatic precipitators. One is the lead-antimony alloy pole line. Due to the limitation of material characteristics, the discharge tip of the pole line cannot be very sharp, and the relative discharge capacity is relatively weak. In addition, the lead-antimony material has poor strength and is extremely After the line is broken, the normal operation of the electrostatic precipitator will be affected, and the dissolved lead in the acidic flue gas will be discharged with the wet collection liquid to form secondary pollution
the other is φ 10-15mm steel pipe surface is welded with the tubular rigid line of the discharge needle, the length of the pole line is generally more than 5 meters, and the slender rod is easy to bend and deform, changing the original design pole spacing, reducing the dust removal efficiency, and the cost is relatively high

Embodiment 1

[0026] Such as figure 1 , figure 2 As mentioned above, the flexible polar wire of the wet dust collector of the present invention includes a cathode wire body 1 made of titanium alloy material. The cathode wire body 1 is twisted from a strip-shaped motherboard, and the twisted body has a spiral strip structure . The outer surface of the discharge area of ​​the cathode wire body 1 is provided with multiple sets of sawtooth discharge tips in gaps along the spiral direction. Each set of sawtooth discharge tips adopts a double-tooth structure. The double-tooth design helps to generate more electrons and helps dust and liquid discharge. drip charge. The distance between two adjacent groups of sawtooth discharge tips (the twisted helical pitch is about 600-800mm) is 30-80mm. A positioning hole is respectively arranged at the upper and lower ends of the cathode wire body. During processing, first use a numerical control punching machine to punch out multiple groups of sawtooth ...

Embodiment 2

[0030] Such as Figure 3-Figure 4 As shown, the flexible polar line of the wet dust collector of the present invention adopts a strip-shaped strip with a thickness of 0.8-1.2mm and a width of 30mm, and a plurality of φ9 mounting holes are punched out at both ends, and the discharge area is separated by a numerically controlled punch. Regular M-shaped sawtooth 2 punched out evenly, the distance between two adjacent M-shaped sawtooths is 30-80mm, the distance between two discharge points in each M-shaped sawtooth is 20-40mm, the tooth height is 8-12mm, and the tip Dimensions can be fine-tuned according to flue gas conditions. Then the discharge area is twisted into a helical strip structure, and the discharge characteristics of the pole line can be adjusted by the spacing of the M-shaped sawtooth and the sharp angle of the tooth tip.

[0031] According to the needs of different working conditions, the cathode wire can be made of titanium alloy, C276 or various duplex stainless ...

Abstract

The invention provides a flexible polar line for a wet type electrostatic dust collector. The straightness of the flexible polar line is good, and tiny dust is not prone to being bonded to the line; and the flexible polar line of the wet type electrostatic dust collector comprises a cathode line body, the cathode line body is formed by twisting a strip-shaped mother board, after twisting is carried out, the body is of a spiral-strip structure, and a plurality of sets of sawtooth discharge tips are arranged on the outer surface of the discharge area of the cathode line body in the spiral direction; each set of sawtooth discharge tips are of a double-tooth structure, and the cathode line is low in discharge inception voltage, large in line current density and even in current; and the discharge dead zone problem of an existing polar line is solved, the straightness is good, and the fine dust is not prone to being bonded on the line.

Description

technical field [0001] The invention relates to the environmental protection field of flue gas deep purification, in particular to a novel flexible cathode wire for a wet electrostatic precipitator with high efficiency, simple structure, and easy manufacture and installation. Background technique [0002] The pole line is a component of the electrostatic precipitator that generates air ionization discharge in a high-voltage electric field to form an uneven high-voltage field strength, and is one of the core components. Therefore, the structural form and installation quality of the cathode line directly affect the dust removal efficiency. [0003] The pole line not only requires good discharge performance (such as high secondary current and voltage parameters), but also has sufficient strength and reliable installation form. At present, two types of polar lines are commonly used in wet electrostatic precipitators. One is the lead-antimony alloy pole line. Due to the limita...
