The High Turbulence acid section represents the latest development in acid cleaning technology. The carefully designed flow patterns effectively break down the boundary layer pocket of spent acid adjacent to the wires, thus continuously supplying fresh acid to their surface. Pickling speed is further increased by the effective scrubbing action of the turbulent acid flow.
In keeping the noonday’s energy conservation concerns, the acid section is designed in a series of modular stages, with each section having a separate optimally sized corrosion resistant pump, turbulence tray and re-circulating loop. The multiple stage design allows lower acid consumption, by the efficient "stepping" of acid concentration levels. The modular system also ensures a lower spare parts inventory cost and eliminates the need of costly back-up pumps.
Salient features of fumeless pickling line are:
Highly Turbulent acid flow,
Multiple stages cleaning,
Straight through wire path,
Double water curtain sealing,
Three stage cascading rinse,
Threading & Wiping Systems,
Self draining acid trays,
Low maintenance design,
Rugged construction.
The two entrance curtains and two rinse curtains are supplied with re-circulated water through special corrosion resistant pumps. The smooth laminar flow curtains effectively seal in the acid fumes and flood the rinse trays. The final rinse is accomplished by high pressure water spray.
