摘要： A system for descaling heat exchanger surfaces using a varying concentration of either an acidic or alkaline solution, selecting an optimum pH value for descaling a heat exchanger according to the level of cleaning the heat exchanger requires, monitoring pH value of descaling solution during circulation through a heat exchanger, and adding chemical solution to achieve coincidence of optimum and monitored pH values during descaling operation.

摘要： A method for automatically cleaning a vehicle's heat exchanger or air filter is provided. In use, once the system determines that the heat exchanger/air filter should be cleaned, for example based on total operational time or the number of use cycles or air flow, the system temporarily reverses the direction of the corresponding fan assembly, thereby reversing the flow of air through the heat exchanger/air filter and forcing out dust, dirt and other debris.

摘要： A boiler system includes a boiler having at least one heat exchanger having a surface on which a deposit may form. The boiler system further includes at least one retractable sootblower having a lance tube for carrying a high pressure fluid into the boiler. The lance tube is configured such that the high pressure fluid impacts the heat exchanger surface to effect a vibration in the boiler system. The boiler system also includes at least one vibration measuring device coupled to the boiler system. The vibration measuring device is configured to measure the vibration in the boiler system, and the measured vibration indicates presence or absence of the deposit on the heat exchanger surface. The vibration measuring device may optionally detect a vibration caused by the release of the deposit from the surface of the heat exchanger or the impact of the released deposit with a surface in the boiler system.

摘要： The present disclosure relates to a method and apparatus for cleaning a 3D printed article, in particular a 3D printed heat exchanger. After 3D printing, an article may have internal passages formed from bonded powder and said passages may contain unbonded powder that needs to be removed before further use of/processing of the article. To remove this unbonded powder, the article is filled with a cleaning fluid and vibrated. The cleaning fluid is then pumped out of the article and past a sensor that generates a magnetic field. The sensor detects the presence of powder particles in the fluid by detecting a perturbation of the magnetic field caused by said particles. The fluid is then filtered and returned to a reservoir for use. The sensor may indicate the article is sufficiently clean when a detected concentration of particles in the fluid drops below a threshold.

摘要： A heat exchanger cleaning device is provided. The cleaning device includes a drive motor configured to rotate a gearbox, a slip clutch and a support beam about a first axis. The support beam carries a thread rod, a second motor, and one or more carriage assemblies. The carriage assemblies move linearly as the second motor rotates the threaded rod. The carriage assemblies include a support tube for receiving an ultra-high pressure tube therethrough. The carriage assemblies adjust relative to the heat exchanger such that the UHP tube may be inserted through the support tube into a hole of the heat exchanger. Therein the UHP tube may be advanced to clean sediment from the heat exchanger tube.

摘要： A heat exchange system includes a shell having an interior with an inlet and an outlet wherein a first fluid circuit is defined from the inlet, through a heat exchange volume within the interior of the shell, to the outlet. A tubesheet is mounted within the shell dividing between the heat exchange volume and a plenum of a second fluid circuit within the interior of the shell. A set of tubes extends through the heat exchange volume, a respective interior passage of each tube being in fluid communication with the plenum through a respective opening though the tubesheet. The second fluid circuit includes the plenum and interior passages of the tubes. A spray nozzle is mounted in the plenum of the second fluid circuit with a spray outlet directed toward the tubesheet for cleaning the tubesheet with a submerged impingement jet issued from the spray nozzle.
