Electrostatic Dust Collector for Lead-Tin Solder Fume Removal

The lead-tin solder fume electrostatic dust collector is primarily used in the manufacturing and maintenance of electrical appliances, electronic products, and household devices. It purifies smoke and fumes generated from lead and tin soldering, including harmful substances such as lead, tin, rosin, and acid-containing dust. The main purpose is to prevent lead poisoning among workers involved in soldering operations and to reduce indoor and outdoor air pollution caused by toxic gases.

Working Principle
The DH series lead-tin solder fume electrostatic dust collector is equipped with a unique impact-suction purification unit. As the fume passes through the device, the high-voltage plasma field ionizes fine particles and gas molecules. The charged fine ions are then collected by the electrostatic unit and deposited into the internal collection box. Harmful gases within the fumes are removed by the activated carbon layer on the side of the electric field, which also eliminates odors. The smoke removal efficiency, as certified by a monitoring agency authorized by the National Environmental Protection Administration, exceeds 91%. Clean air is released through the outlet, meeting emission standards.

Technical Features
- The purification unit uses a cascaded, multi-stage electric field configuration that efficiently captures particles of various sizes, achieving an average purification rate above 90%.

- The high-frequency electrostatic power control system automatically adjusts the electric field strength to ensure consistent purification performance even after long-term operation.

- Each purification unit is individually connected to the high-frequency power control system, allowing real-time monitoring of each unit’s operating status for easier inspection and maintenance.

- The control system includes over-current and over-voltage protection to ensure operational safety.

- The number of purification units can be flexibly adjusted according to purification requirements, helping reduce equipment costs.
Each purification module adopts a separate drawer-style design, making installation and cleaning convenient.

- The equipment is compact, lightweight, and requires minimal floor space.

- Corrosion-resistant materials are used throughout, giving the system a long service life.

- The DH series lead-tin solder fume electrostatic dust collector is an improved version based on imported models, featuring an internally developed hybrid impact-suction unit. It has passed product evaluation by the Science and Technology Bureau and is recognized as a domestic innovation that fills a gap in the national market.

Applications of the DH Fume Purifier

Welding operations often generate toxic substances such as acetaldehyde, abietic acid (rosin), isocyanates, and hydrocarbons. These harmful substances severely affect human health and contribute to the development of various occupational diseases, including lung cancer, asthma, eczema, bronchitis, skin allergies, and respiratory infections. The DH series lead-tin solder fume electrostatic dust collector provides an effective air purification solution.

- Welding Fume Purification

Capable of simultaneously serving 1 to 6 soldering stations. Recommended suction hose length not to exceed 6 meters.

- Wave Soldering and Reflow Soldering Fume Purification

When used with DH series electrostatic purifiers, fumes generated from reflow ovens and wave soldering machines can be purified and recirculated indoors. This avoids the need for external emissions and eliminates the installation of complex ductwork systems. It also helps maintain indoor air pressure and cleanliness.

- Electric Welding Fume Purification

Suitable for 1 to 2 welding stations at the same time. Suction hose length should not exceed 3 meters.

- Laser Engraving Fume Purification

Suitable for 1 to 2 workstations. Suction hose length should not exceed 3 meters.
