Cleaning system having heated cleaning enclosure for cleaning heat exchanger tube bundles

摘要

An improved portable cleaning system for use in cleaning heat exchanger tube bundles, fin-fans, towers and other elongated components. The cleaning system comprises a cleaning unit having a cleaning enclosure that receives and cleans the component and a control unit that controls the operation of the system. The cleaning unit has a cleaning enclosure defining a chamber sized and configured to receive the component through a sealable lid. A roller assembly rotates the component while a spray assembly sprays cleaning fluid over and into the rotating component. The cleaning fluid is heated in the chamber using surface heating elements attached to heat transfer plates along sections of the chamber walls. A vapor recovery system captures and treats toxic vapors. In use, the cleaning system is transported to a facility to clean the components on-site using cleaning fluid supplied by the facility and discharging waste to the facility.

主权项

1. An apparatus for cleaning one or more large-scale, industrial, elongated components, the apparatus comprising:
a cleaning chamber defined by a sidewall, an endwall and a bottom wall, the sidewall comprising a heater cavity, the cleaning chamber sized and configured to receive the one or more large-scale, industrial, elongated components selected from a group consisting of heat exchanger tube bundles, fin-fans, and cooling towers; a control unit which controls the functioning of the apparatus; a lid configured to sealably close the cleaning chamber; a roller assembly configured to rotate the one or more elongated components within the cleaning chamber; a heating system to heat a cleaning fluid placed in the cleaning chamber, the heating system comprising one or more heating elements disposed within the heater cavity and against a heat transfer plate, the heat transfer plate in thermal-conductive communication with the cleaning chamber; a pump system configured to pressurize the cleaning fluid; a spray assembly configured to spray the cleaning fluid onto the one or more elongated components inside the cleaning chamber; and a means of providing positive pressure to the heater cavity to prevent introduction of the cleaning fluid into the heater cavity.
