A remote controlled portable resonance induction cleaning system for cleaning a process tubular or heat exchanger can include a portable high pressure plunger pump, which can provide a liquid to the portable resonance induction cleaning apparatus, The remote controlled portable resonance induction cleaning apparatus can regulate flow of the liquid to provide pressurized pulses of the liquid with a resonance for removing fouling. A hose assembly or ram connecting mechanism can provide the pressurized pulses of the liquid to the process tubular or heat exchanger. Air can be used to control flow of the pressurized pulses of the liquid. A hydraulic intensifier can be in fluid communication with the remote controlled portable resonance induction cleaning apparatus for receiving the air, and a hydraulic control valve can be bi-directionally engaged with the hydraulic intensifier and the hydraulic ram. The hydraulic ram can seal with the heat exchanger to provide the pressurized pulses of the liquid thereto.

The present invention relates to systems and methods for cleaning of devices, such as heat exchangers. According to the invention, controlled cavitation is created at predetermined positions within a device. The cavitation is done by mechanical waves, such as ultrasound waves, generated by transducers, wherein the waves are based on output of time-reversal wave form analysis of the device structures.

A heatsink comprising a heat exchange device having a plurality of heat exchange elements each having a surface boundary with respect to a heat transfer fluid, having successive elements or regions having varying size scales. According to one embodiment, an accumulation of dust or particles on a surface of the heatsink is reduced by a removal mechanism. The mechanism can be thermal pyrolysis, vibration, blowing, etc. In the case of vibration, adverse effects on the system to be cooled may be minimized by an active or passive vibration suppression system.

Disclosed is a method for identifying and eliminating ammonium salt deposition characteristics in a pipe of a hydrogenation air cooler. A multiphase flow medium enters an inlet pipe box of a hydrogenation air cooler; cross sections and temperature transmitters are arranged on a pipe bundle of the air cooler in the axial direction; a temperature signal value is monitored and transmitted to a single-chip microcomputer for analysis; an infrared thermal imager performs photographing, and transmits data to determine that an ammonium salt deposition risk is present under this working condition; a monitored temperature value is calculated, an ammonium salt deposition risk identification model is established, and ammonium salt deposits are peeled off from the inner wall of the pipe bundle of the air cooler by means of vibration of the pipe bundle caused by the intermittent frequent switching-on/switching-off of an electromagnet and a magnetic block, and ultrasonic signals.

A method and cleaning device for removing deposits from interiors of receptacles and installations by way of explosion technology. The cleaning device includes a cleaning apparatus with a receiving space, and at least one pressure container that is connected via at least one metering fitting to the cleaning apparatus. The controlled introduction of the at least one gaseous component into the cleaning apparatus is effected according to the principle of the differential pressure between a maximal pressure at the beginning of the introduction and a nominal residual pressure after completion of the introduction. For this, based on a maximal pressure, the nominal residual pressure in the pressure container is ascertained on the basis of the quantity of gaseous component to be introduced, and the introduction of the at least one gaseous component is stopped on reaching the nominal residual pressure, which thereby lies in the overpressure range.

Condenser-evaporator tube, in whose interior flows a vapor to be condensed and over which flows a liquid to be evaporated, where both inside and outside faces of this tube are covered with capillary structures configured for the formation of liquid menisci having a contact angle smaller than 90? where the liquid-vapor interface curves, which allows capillary condensation inside the tube and evaporation on the outside face at the upper end (25) of the liquid menisci where the liquid layer is thinnest and the evaporation most efficient.

An online cleaning system for tube and shell heat exchangers is presented. The system includes a positioner, a plunger, an umbilical cleaner, and a motor. The cleaning system cleans the tubes while the heat exchanger remains in operation. The cleaning system locates and isolates a single tube via rotating and translating mechanical actions and inserts the umbilical cleaner into the tube, which may clean the tube via rotational movement or via sonication. The cleaning system may further clean the outer surface of the tubes of the heat exchanger.
