Definitions

  • a cleaning system for cleaning the inside of fluid conducting tubing, the cleaning system comprising: (a) a plurality of balls entrained by a fluid flowing through the system; (b) separation apparatus for separating the balls from the fluid downstream of the tubing; (c) accumulator apparatus for accumulating the balls downstream of the separation apparatus; characterised by (d) storage apparatus for storing a volume of injection fluid, the storage apparatus being in communication with the accumulator apparatus, the storage apparatus being in communication with a point upstream of the tubing; and by (e) a compressor for selectively providing a supply of compressed air into the storage apparatus for injecting a portion of the volume of injection fluid from the storage apparatus to the point upstream of the tubing, a fraction of the volume of injection fluid passing through the accumulator apparatus for entraining some of the balls therewith for injection upstream of the tubing.
  • the apparatus further comprising a second separation apparatus in parallel with the first separation apparatus, the second separation apparatus including a conduit having an inlet in flow communication with the downstream side of the tubing, a ball outlet connected to the inlet of the ball recirculation apparatus and a fluid outlet connected to an outlet fluid line, and a generally cylindrical sieve substantially extending between the inlet and the ball outlet.
  • FIGS. 1a-1c are schematic views of a cleaning system, generally designated 10, constructed and operative according to the teachings of the present invention, for cleaning a condenser 12 at different stages of operation.
  • Condenser 12 includes fluid conducting tubing 14 through which a cooling liquid, such as water, passes to condense a fluid, such as steam or refrigerant gas, passing through spaces between condenser tubing 14.
  • the cooling fluid is pumped by a pump 20 through a closed circuit including an inlet conduit 22 at the upstream side of condenser 12 connected to the inlet header 16 of condenser 12, condenser tubing 14, and an outlet conduit 24 at the downstream side of condenser 12 connected to the outlet header 18 of condenser 12.
  • ball recirculation apparatus 30 includes four elements.
  • Trap 60 preferably has sufficient storage capacity to accommodate all balls 26 in circulation.
  • Tank 62 can be filled either by run-off from trap 60 or from a separate source of fluid (not shown) and preferably has sufficient storage capacity for injecting all the balls stored in trap 60 into the mainstream fluid flow.
  • ball recirculation apparatus 30 is activated such that the prevailing pressure in tank 62 suddenly drops below the prevailing pressure within outlet conduit 24.
  • the sudden pressure drop causes a relatively abrupt diversion in the flow of cooling fluid through separation apparatus 28 such that most of the cooling fluid is discharged through ball outlet 50 along conduit 32 instead of through fluid outlet 48 along outlet conduit 24.
  • balls 26 are evacuated therefrom by an intense vortex of cooling fluid entraining balls 26 through ball outlet 50 toward ball recirculation apparatus 30.
