VOCCSYS
Why is Micro Fouling a Problem?
Micro Fouling occurs due to continuous heating and cooling of water, accumulation of colloidal particles, decomposition of suspended matter, spread of bacteria and algae in the water, or even due to a combination of reasons
Micro Fouling is the accumulation of unwanted material on the inner walls of Heat Exchanger Tubes that are heavily damaging and is severely detrimental to the functioning of your Heat Exchanger
Micro Fouling causes losses in industrialized India and China of more than $22.89 billion USD. Sustained and uncontrolled micro fouling causes increased output losses in Steam Turbines, reduction in gained output ratio in Desalination Plants, and extra power consumption in Chillers
What is VOCCSYS?
The Vulcan Online Condenser Cleaning System is an automatic tube cleaning system that uses Vulcan condenser cleaning sponge rubber balls to prevent any micro fouling building up on the inner walls of the heat exchanger tube. VOCCSYS is completely automatic and runs parallel to the heat exchanger such that the cleaning takes place while the heat exchanger in in operation.
During operation, Vulcan Condenser Cleaning Balls (VCCB), slightly larger than the tube ID, are injected on the inlet side of the heat exchanger from the Ball Collector. These Cleaning balls are introduced in a manner such that they form a random distribution. The velocity of the water compresses the balls as they enter a tube. The system velocity propels the balls through the tubes, thus wiping the inner walls to remove impurities, silt, and filming, and prevent buildup. Upon discharge, the cleaning balls are captured and retained in the condenser discharge line in a Ball Trap. The cleaning balls are pumped back to the Ball Collector for rinsing and re-circulation. VOCCSYS utilizes an HMI touch screen control interface, allowing for easy monitoring. Individual or multiple systems can be controlled from a common panel.
How does VOCCSYS work?
Water Inlet
Ball Trap
Water Outlet
Heat Exchanger
Ball Collector
PLC Controller
Re-circulation Pump
1. Injection Cycle
Water from the inlet line is diverted by the Re-circulation pump to flood the Ball Collector and the Cleaning Sponge Balls are then injected into the Heat Exchanger Inlet line at the same time
3. Collection Cycle
Once the Cleaning balls have cleaned the tubes of the Heat Exchanger they exit and are separated from the main water flow by the Ball Trap. The Re-circulating pump then returns these balls back to the Ball Collector for rinsing and the next cycle.
2. Cleaning Cycle
All the Cleaning Balls travel through the tubes of the Heat Exchanger removing any build-up and fouling that may have formed on the inner walls of the tubes
4. Stand-by
In between cycles the system powers down to make sure that only the minimum power is utilized to keep the Heat Exchanger clean.
