Energy Saving Spiky Brush Balls for Tube Cleaning
Industry Background
There are several types of microfouling that pose a constant problem to heat exchanger tubes: biological fouling (due to biofilm & slime), precipitation fouling (due to crystallization/scale), particulate fouling (due to sedimentation of suspended solids) and corrosion fouling (due to galvanic action).
Those micro-fouling causes problems of ;
l Reduces heat transfer efficiency
l Affects flow pattern
l Increases pressure loss
l Causes higher energy use
l Shortens run cycle
l Disrupts throughput
l Triggers unscheduled outages
l Increases operation costs
Technology summary
Driven by the water flow through the heat exchanger, the mechanical movements of appropriately proportioned, sized and weighted Brush Balls bounce and rotate with high velocity, constantly scrubbing and removing the dirt and scales in the heat exchanger tubes.
The foulings in the tubes are the bushed and flushed out by these balls as they dynamically scrub and work their way along the tubes. Due to the removal being a physical and mechanical process and Brush balls being smaller then the internal diameter of tubes, it is not subject to any pressure loss across heat exchanger, the variability of fluid chemistry and flow velocity.
Benefit
The System allows no fouling to accumulate from system commission since the HVS cleaning process operates on a continual basis. Once the cleaning balls enter the tubes, they move on their own accord without the need for additional energy input. Automatic Cleaning can save energy in the magnitude of 5%-30% as the continuous circulation of HVS Cleaning Devices keep the internal surfaces of tubes constantly and consistently clean, maintaining optimal heat transfer efficiency.
l Provides “green” method of eliminating tube fouling, thus eliminating significant energy wastage, reducing environmental impact & decreasing greenhouse gas emissions.
l Eliminates the need for offline cleaning, where the results are only temporary.
l Eliminates water waste and better utilizes human resources.
l Provides 100% fail-safe, non-invasive design and utilizes elastomeric balls that will not break apart or clog tubes.
l Cleans standard or enhanced tube applications.
l Improves equipment life by enabling chillers & process heat exchangers to constantly run at peak efficiency.
l Requires no additional system pumping power. Improves uptime and process yield.
Opportunities
The company is looking for:
l Strategic business partners
l Licensing partners ; and /or
l Customers to adapt technology in their products
