Refactoring around the walls has always been a problem when it comes to cleaning furnace convection banks or reactor center-pipes. Dry-Ice blasting was recently used in cleaning convection banks, APH and it prove to be the most effective ways for removing soots without fear of damaging refactoring. It was safe, no waste generation as CO2 evaporate and much faster in terms of preparation and cleaning time.
ADVANTAGES OF DRY ICE BLASTING
TuffChem provides fast and effective industrial cleaning services utilizing dry ice blasting.
Dry ice blasting uses high-velocity dry ice pellets to clean surfaces without damaging equipment, and provides a number of significant advantages over other types of industrial cleaning:
o No labor-intensive manual scrubbing or caustic chemicals/solvents.
o The dry ice vaporizes into harmless gas on impact, so no secondary waste
is created.
o Equipment can usually be cleaned in-place - without expensive disassembly
Dry ice is completely environmentally friendly and harmless to employees. In
addition, dry ice blasting is faster, more convenient, and more cost effective
than ‘traditional’ cleaning methods.
HOW IT WORKS
Dry ice blasting is a process in which particles of solid carbon dioxide, commonly known as dry ice, are propelled at high velocity to impact and clean equipment, machinery, and structures without damage to electrical wiring, hoses, sensors, or other delicate components.
Traditional abrasive blasting methods clean through a chiseling action, like using a pick, but can damage the surface below. Dry ice, on the other hand, might better be compared to a spatula as it lifts away the contaminant.
Using Chemical Cleaning means generating waste, refactoring gets damages, longer preparation time and it is a hazardous for all equipment, man and environment.
The dry ice pierces the contaminant and ‘explodes’ into its gas form instantly upon striking the substrate beneath. This harmless explosion creates a shock wave between the coating and the surface and literally pops off contaminants from the inside out.
Utilities: Our non-abrasive process cleans turbine components, economizer fins, generator windings, transformers, insulators and more without creating any secondary waste.
Printing: Removes both wet and dry ink, coatings and grease from continuous web and sheet fed presses. Dry ice blasting is about eight times faster than hand cleaning and provides superior results.
General Maintenance: Clean your equipment in place. Removes oil, grease, weld slag, and overspray; cleans ductwork, electrical equipment, conveyors, cooling fins, and more. Our technology is also ideal for removing tar, construction adhesives, paint, overspray, and cement spatter from concrete, masonry, and other surfaces.
Disaster Cleanup: Coldsweep offers cost effective cleaning alternatives for mold remediation, electrical fires, and smoke damage.
Architectural/Restoration: Distress floors, windows doors and other surfaces to create weathered and worn look. Our non-abrasive dry ice blasting process cleans masonry walls without damage to mortar or bricks.
HAZMAT: Removes radioactive materials, hazardous spills, asbestos, lead paint, and other materials without creating secondary waste. Dry ice blasting can significantly reduce your hazardous waste disposal costs.
