Abstract: A method for cleaning tubes and heat exchangers as set forth. The method and apparatus involve an elongate lance which is mounted to move in an X and Y pattern to align with a set of tubes. Each tube is cleaned by positioning the lance at the end of each tube to be cleaned. A plug is placed in the tube to be cleaned to form a standing column for water. By means of a valve control system, the standing column of water is cycled from low to high pressure by switching the flow of water. In this switched mode, water is delivered under pressure into the column. The lance tip functions in conjunction with an orifice upstream of the lance tip to form a shock wave of energy radiating along the standing column of water from the orifice into the tube to be cleaned. The addition of water to the tube ultimately moves the plug along the length of the tube. It is one theory of operation of the present disclosure that the column of water exposed to shock waves is used in cleaning, i.e.

Abstract: An ultrasonic cleaning apparatus for cleaning the interior surfaces of tubes. The apparatus includes an ultrasonic generator and reflector each coupled to opposing ends of the open-ended, fluid-filled tube. Fluid-tight couplings seal the reflector and generator to the tube, preventing leakage of fluid from the interior of the tube. The reflector and generator are operatively connected to actuators, whereby the distance between them can be varied. When the distance is changed, the frequency of the sound waves is simultaneously adjusted to maintain the resonant frequency of the tube so that a standing wave is formed in the tube, the nodes of which are moved axially to cause cavitation along the length of the tube. Cavitation maximizes mechanical disruption and agitation of the fluid, dislodging foreign material from the interior surface.

Abstract: This invention concerns a system for insuring and accurately controlling the turbulent flow of a pressurized mixture of a gas and a cleaning fluid for purging and cleaning ducts. The pressures of cleaning fluid and the gas are continuously sensed and transduced into electrical signals for controlling valves for the pressurized gas to maintain and insure its pressure at a predetermined amount relative to the pressure of said cleaning fluid, so that when the gas and fluid are mixed in a turbulator, turbulent flow is insured. The improvements of this circuit include a pressure sensor transducer for sensing the pressure of the input of the air to the turbulator and feeding it back to the main air pressure transducer for accurately maintaining a predetermined ratio between the gas and cleaning fluid pressures within less than about 1 psi in at least pressures of 150 psi. A pressure warning signal indicates when the gas and/or cleaning fluid pressure is too low to produce effective turbulent flow.

Abstract: An apparatus and a method are disclosed for the removal and the recovery of washcoat remaining in the channels of freshly coated monolithic or honeycombed catalytic carriers. The carrier is inserted into a chamber from above and tightly fitted therein at least with the lowest part of the carrier therein. The chamber is fitted with a collection area and a runoff located thereunder. The runoff leads via a shutoff valve into a separation vessel under a vacuum.

This action causes the washcoat remnants to be transferred into the separation vessel, where they can be collected in the sump and are then pumped off. The apparatus can be used in systems for manufacturing catalysts for cleaning exhaust gases.
