Overview

This allows charged particles to be quickly adsorbed onto the collecting electrode surface, completing gas-solid and gas-liquid separation. The uniformity and stability of the cathode wire's discharge directly determine the purification efficiency and ultra-low emission effect of the electric field. It is an essential core component for establishing an effective electric field and stabilizing dust removal performance in an electrostatic precipitator system.

Characteristics

The discharge tip layout is scientifically uniform, the corona discharge intensity is stable, and the corona initiation voltage is low. It can form a uniform electric field throughout the entire area, with no discharge dead zones. It can fully activate the charging of fine dust particles, significantly improving the capture efficiency of ultrafine particles and ensuring long-term high-efficiency purification of the equipment.

Made from high-quality materials such as stainless steel and high-strength alloys, it boasts strong overall toughness and high tensile strength, making it resistant to breakage and deformation. It can withstand long-term rapping impacts, flue gas erosion, and high-voltage electric field loads, suitable for 24-hour continuous industrial operation.

It exhibits excellent temperature resistance, corrosion resistance, and aging resistance, making it suitable for harsh conditions such as high-temperature dry flue gas, high-humidity saturated flue gas, and trace acid and alkali corrosion. It is resistant to rust, scale buildup, and passivation during long-term operation, maintaining consistent discharge performance.

The structure effectively prevents dust accumulation, with a smooth surface that resists dust adhesion. Combined with automatic rapping cleaning, it quickly removes dust, effectively preventing discharge weakening, electric field shift, and frequent flashover trips caused by scale buildup on the cathode wires.

The standardized modular design features precise installation hooks, high interchangeability, and convenient disassembly and maintenance. On-site assembly ensures neat alignment, effectively guaranteeing uniform electrode spacing and stable high-voltage electric field output and purification effect.

Suitable Applications

Widely compatible with various dry and wet electrostatic precipitators and high-voltage electric field systems. Primarily used in deep treatment of high-temperature, high-humidity, and corrosive flue gas from thermal power generation, heating, metallurgical sintering, cement kiln tail, chemical tail gas, waste incineration, and biomass combustion, etc. Suitable for both new industrial electrostatic precipitators and the retrofitting of older equipment.

Maintenance Design

The equipment comes standard with complete cathode wires, fixing hooks, tensioning components, and insulating connectors, offering a full range of accessories and strong versatility. The overall structure is robust, with a low failure rate and excellent fatigue resistance. Customization is supported for various types and specifications, including sawtooth wires, barbed wires, herringbone wires, and spiral wires. Custom models and materials can be matched according to electric field parameters, flue gas conditions, and dust characteristics, ensuring compatibility with new and old dry and wet electrostatic precipitators for installation, replacement, and upgrades.

Note

The cathode wire is the core discharge component of the electrostatic precipitator. Broken wires, deformation, ash accumulation and passivation, and electrode spacing misalignment will all cause insufficient electric field output and a sharp drop in dust removal efficiency. Regular checks of the wire's integrity and discharge status are necessary, with timely repair and replacement to ensure stable and efficient operation of the electric field.
