Abstract
A cleaning apparatus comprising a first fluid delivery system configured to eject a first fluid through a first nozzle toward a surface to be cleaned; a second fluid delivery system configures to eject a second fluid through a second nozzle toward the surface to be cleaned, wherein the second fluid comprises a compressed gas at a pressure greater than 345 kilopascals (50 pounds per square inch); a housing configured to partially surround and mount the first and second nozzles; a connector configured to couple the first fluid delivery system to a first fluid source; and a connector configured to couple the second fluid delivery system to a second fluid source.
Claims20
A cleaning apparatus comprising:
- a first fluid delivery system configured to eject a first fluid through a first nozzle toward a surface to be cleaned;
- a second fluid delivery system configured to eject a second fluid through a second nozzle toward the surface to be cleaned, wherein the second fluid comprises a compressed gas at a pressure greater than 345 kilopascals (50 pounds per square inch);
- a housing configured to partially surround and mount the first and second nozzles;
- a connector configured to couple the first fluid delivery system to a first fluid source;
- and
- a connector configured to couple the second fluid delivery system to a second fluid source.
A cleaning apparatus configured to clean a coil of a heat exchanger, comprising:
- a spray nozzle configured to deliver a first fluid;
- a discharge channel with a plurality of apertures configured to deliver a second fluid,
- a housing configured to mount and surround the spray nozzle and the discharge channel to allow delivery of the first and second fluids to the coil, wherein the discharge channel is configured to deliver the second fluid into a discharge stream of the first fluid;
- a first connector configured to couple the spray nozzle to a first fluid source;
- a second connector configured to couple the discharge channel to a second fluid source;
- and
- at least one valve to adjust at least one of a first or second fluid flow rate or pattern of discharge.
A method for cleaning a heat exchanger coil comprising:
- connecting a first fluid delivery system to a first fluid source, wherein the first fluid comprises a cleaning agent selected from the group consisting of water, solvents, detergents, and a combination thereof;
- connecting a second fluid delivery system to a second fluid source, wherein the second fluid comprises a compressed gas;
- delivering a first fluid through a first nozzle of the first fluid delivery system toward the coil in a fluid stream, wherein the first nozzle is mounted in a cleaning apparatus housing;
- delivering a second fluid through a second nozzle of the second fluid delivery system, creating a second fluid stream, wherein the second nozzle is mounted in the cleaning apparatus housing;
- adjusting at least one of the rate and pattern of flow of at least one of the first and second fluid delivery systems with valves connected to the cleaning apparatus to create a fluid mixture capable of removing particulate matter from the narrow passageways of the heat exchanging coil without bending coil fins;
- and
- positioning the cleaning apparatus housing within 0.5 meters of the coil.
