Title:

Electrostatic Dust Mitigation and Smog Control Device

Value Proposition:

Dust is a pervasive problem in handling bulk materials such as coal, cement, construction, demolition of buildings, thermal power plants, etc., interfering with all aspects of operations. Dust suppression systems help to control the dust while improving efficiency. An electrostatic dust mitigation device is highly useful in suppressing the dust particles entrained in the air and protecting the environment in an efficient way. It produces uniform and fine spray particles that are nearly equal in the proportion of dust particles. The present invention and utility model discloses a multipurpose air-induced air-assisted high-range electrostatic spraying system based on the induction charging principle for dust mitigation and smog control. The major source for such pollutants is industrial, vehicular, domestic, agricultural, and other emissions. This technology uses an electrostatic field to generate charged spray droplets which combine with oppositely charged dust and smog particles and settle down onto the ground very efficiently and effectively.

Summary Application:
  • Coal mines
  • Paper industry
  • Cement industry
  • Misting in rural area
  • Thermal power-plants
  • Hotels and restaurants
  • Stone crushing industry
  • Clay and brick manufacturing
  • General pollution / Airborne dust
  • Industrial sanitization and disinfection
Advantages:
  • Charged droplets are more effective in suppressing dust particles
  • Globally competitive, at par with international standards
  • Cost-effective solution with higher efficiency
  • Mobilization is very easy
  • Easily mounted on a trolley or moving vehicles
  • Produces fine spray droplets
  • Anti-corrosion resistance cannon material
  • Less amount of water is required
  • Low power consumption
  • Low maintenance
