HYDRO-LANCE™

HYDRO-LANCE™ WET SCRUBBERS FOR PARTICULATE CONTROL

The HEE-Duall HYDRO-LANCE™ wet particulate scrubbing system is comprised of venturi impactors, liquid level controls, fans, recycle tanks, sludge drag-out chambers, mist eliminators, control panels, ducts, and hoods, all sold as a unit.

With Venturi scrubbers, the dirty gas entering a scrubber is forced at high velocity through a Venturi where it collides with scrubbing water. The tiny water droplets capture particles through impaction and diffusion. The dirty water is then removed in a cyclonic separator and discharged into a recycle tank. Some of the liquid is continuously purged to limit the solids concentration and allow recirculation back to the Venturi section.

However, Venturi scrubbers can experience pump failures, small orifice nozzle clogging, and material failures. To avoid these issues, we offer the Hydro-Lance™ Wet Scrubber system, which combines proven Venturi collection methodology using with our HEE-Duall SAVe (Sub-merged-Air-Venturi) technology.

In terms of the principles of operation for the Hydro-Lance™ Wet Scrubber, static pressure induced by an exhaust fan draws the sump water and dust-laden air stream into an inverted Venturi throat. Turbulent mixing of dust and small droplets form an agglomerate, which is returned to sump where water is reused and particulate matter settles out or is dissolved. Entrained mists and dust are collected on a chevron blade mist eliminator. The collected dust forms sludge at the conical bottom of the scrubber.

Ideal Applications Include:

• Aluminum, titanium and other metal machining operations
• Sodium Azide propellant manufacturing and handling
• Pharmaceutical powders and dusts
• Calcium chloride dusts
• Hygroscopic dusts
• Corrosive dusts
• Food processing with clean in place (CIP) option
• Bulk solids drying process
• Battery lead pasting
