A method of cleaning a component within a turbine that includes disassembling the turbine engine to provide a flow path to an interior passageway of the component from an access point. The component has coked hydrocarbons formed thereon. The method further includes discharging a flow of cleaning solution towards the interior passageway from the access point, wherein the cleaning solution is configured to remove the coked hydrocarbons from the component.

The invention relates to a device and a method for cleaning a drain pipe or a pipe connected thereto, by ensuring the formation of successive distinct water waves flowing in the pipe, with or without additive(s).

A cleaning method includes a first removal step of causing an inert gas to which a pulsation is applied to flow into an exhaust pipe after a silicon single crystal doped with an n-type dopant is produced, to peel and remove a deposit; and a second removal step of causing an atmospheric air to which no pulsation is applied to flow into the exhaust pipe through a chamber to burn a part of the deposit with the atmospheric air, the part being not removable in the first removal step, and peel and remove a burned substance of the deposit.

A cleaning apparatus for concentration controller of coating machine may include a pulse bubble generator and a container used for cleaning a concentration controller of a coating machine and a tube thereof. The pulse bubble generator has a bubble-generating end connected to the container through a pipe, and the container is filled with a plentiful detergent. The pulse bubble generator is configured to pump air into the detergent with a pulse per time, and a large amount of detergent bubbles are adapted to be generated in the container. The detergent bubbles are configured to be pumped by the concentration controller into the tube and the concentration controller so as to complete cleaning effect of the tube and the concentration controller.

A method for cleaning and/or disinfecting a milk-carrying system of a coffee machine for producing coffee mix drinks, and a coffee machine for carrying out the method has the aim of allowing the entire milk-carrying system to be cleaned, completely and in a way that can be easily automated. The milk delivery line is separated from the milk container, for carrying out the cleaning Process, and is connected to a first container, and a second container is arranged under a milk outlet of a milk preparation device of the milk-carrying system. Fluid is then delivered to fluid inlet in order to convey the active cleaning and/or disinfecting substance through the milk delivery line and a milk outlet into the second container. Thereafter, water is conveyed to the air inlet and the fluid inlet is closed, in order thereby to flush the milk-carrying system.

The present disclosure relates to a cleaning module-integrated beverage dispensing head, capable of selectively providing a cleaning function in addition to a conventional beverage dispensing function. A cleaning module-integrated beverage dispensing head includes a gas distributor (200) outputting a gas flowed in, and a pulse generator (100) receiving a supply of the gas supplied via a hose (300). The gas distributor (200) includes a first gas outlet (220) discharging the gas to the pulse generator (100), a second gas outlet (230) discharging the gas to a container (C) for storing liquid, an internal structure (200a) that is rotatable, and an external structure (200b) that is coupled to the internal structure (200a), to control rotation of the internal structure (200a). Whether or not to supply the gas to the pulse generator (100) through the first gas outlet (220) is determined according to whether or not the internal structure (200a) rotates.

A gas lift pump apparatus for treating ballast water includes a column through which a liquid medium, such as seawater, may be pumped by gas lift. The apparatus includes a delivery device for delivering a flow of a gas into the liquid medium, and a resonance chamber that generates ultrasonic energy therein by the flow of the gas therethrough. The apparatus is operable to launch the ultrasonic energy into the liquid medium in the column.

A cleaning apparatus for concentration controller of coating machine may include a pulse bubble generator and a container used for cleaning a concentration controller of a coating machine and a tube thereof. The pulse bubble generator has a bubble-generating end connected to the container through a pipe, and the container is filled with a plentiful detergent. The pulse bubble generator is configured to pump air into the detergent with a pulse per time, and a large amount of detergent bubbles are adapted to be generated in the container. The detergent bubbles are configured to be pumped by the concentration controller into the tube and the concentration controller so as to complete cleaning effect of the tube and the concentration controller.

A nozzle cleaner includes: a cleaning tank which stores a cleaning solution; a first conductive member that is disposed to be immersed into the cleaning solution stored in the cleaning tank when the nozzle is cleaned; an ultrasonic wave generating mechanism which is disposed so that at least a part of a second conductive member is immersed into the cleaning solution stored in the cleaning tank when the nozzle is cleaned and generates an ultrasonic vibration in the cleaning solution stored in the cleaning tank; a first voltage control unit which controls a potential applied to the first conductive member; and a second voltage control unit which controls a potential applied to the second conductive member, wherein the first voltage control unit applies a second potential V.sub.2 higher than a first potential V.sub.1 applied to the nozzle when the nozzle is cleaned to the first conductive member.

A method for cleaning firearm suppressors comprising: providing a used suppressor having an internal cavity with a fouling material deposited on a surface of the internal cavity; providing a cleaning solution; providing an ultra-sonic probe; introducing the cleaning solution into the internal cavity of the used suppressor; contacting at least part of the ultra-sonic probe with the cleaning solution that is introduced inside the internal cavity of the used suppressor; operating the ultra-sonic probe; removing at least part of the fouling material from the surface of the internal cavity of the used suppressor; and, draining the cleaning solution from the used suppressor.
