摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A heat exchanger for separating a vapor component from a carrier gas is disclosed. The carrier gas is cooled in an outer chamber, causing a vapor component of the carrier gas to desublimate or condense onto an outer surface of an inner chamber, forming a solid product. A coolant is passed through the inner chamber to cool the carrier gas of the outer chamber. A means for causing the inner chamber to flex is provided, causing the solid product to fall from the outer surface of the inner chamber for collection. In this manner, the vapor component is separated from the carrier gas.

摘要： Cleaning the inside surfaces of tubes in a cracking furnace, or other type of structure with tubes, is very difficult and time consuming. An acoustic energy cleaning apparatus is provided that is clamped onto a tube, and a liquid solvent is filled within the tube. The cleaning apparatus includes an ultrasonic transducer that causes cavitation of the liquid inside the tube, which dislodges material build-up. The apparatus also includes a rigid seal cover that encompasses a lower portion of a transducer housing, and an annular resilient seal positioned within and below the seal cover. The apparatus also includes an injection hole that fluidly connects a space, defined at least by the annular resilient seal and a bottom surface of the acoustic transducer, to an external environment. A user injects gel into the injection hole.

摘要： An apparatus for underwater pipes comprising an ultrasound emitting system and at least one ultrasound receiving transducer is lowered into he marine environment. During an inspection phase, an ultrasound inspection source of the ultrasound emitting system and the receiving transducer are disposed on each side of the pipe. The inspection source is activated, and an ultrasound signal captured by the receiving transducer is recorded. In response to the observation of an anomaly in the ultrasound signal captured by the receiving transducer, a power source of the ultrasound emitting system is then coupled to the pipe at the aforementioned location, and the power source is activated in order to destroy the obstruction.

摘要： A system and method are disclosed for using a sonic frequency to induce a vibration useful for clearing dust accumulation from microelectronics, such as a laptop computer. A speaker driver may be mounted onto a support structure for a heat exchanger (220). At an advantageous time, such as boot up, a sonic frequency may be driven onto the speaker (250), thus inducing vibration in the heat exchanger (220) and helping to clear dust accumulation. In some cases, a resonant frequency may be used to optimize the amount of vibration per unit power delivery.

摘要： A water heater in which by applying pulsation of a liquid to be heated which circulates between a tank and a heat exchanger, scale that has been deposited on the inner wall (heat-transfer surface) of a to-be-heated liquid flow channel in a heat exchanger is detached, and the number of times of circulation of the liquid to be heated which circulates between the tank and the heat exchanger is controlled to be three times or less. The number of times of circulation is determined, based on the entire volume of the to-be-heated liquid stored in the tank, a boiling time to be taken for the entire volume of the to-be-heated liquid in the tank to reach a predetermined temperature, and the flow rate of the to-be-heated liquid which passes through the to-be-heated liquid flow channel.
