Abstract: A retractable cleaning apparatus for spray cleaning of pipes or vessels comprises a rotatable spray head configured to spray the interior of the pipes or vessels with a cleaning liquid. The rotatable spray head is linearly movable between a retracted position and a cleaning position along a longitudinal axis of the rotatable spray head. The rotatable spray head is rotatable about the longitudinal axis of the rotatable spray head independent of a flow of the cleaning liquid. The rotatable spray head is rotatable with an angular velocity that is independent of the flow of the cleaning liquid. The angular velocity may be within a range of 0.1-1.3 radians per second. A system including a retractable cleaning apparatus is also disclosed.

Abstract: A liquid ejection apparatus for cleaning of a tank. The liquid ejection apparatus comprising: a base member having a first end for receiving the liquid from a liquid line, a rotary head that is rotatably connected to the base member and a rotary nozzle hub that is rotatably connected to the rotary head. The rotary nozzle hub comprises a primary liquid ejection nozzle for ejecting a liquid in a pattern towards an interior surface of the tank, and a secondary liquid ejection nozzle that is configured to, during at least a part of a revolution of the rotary nozzle hub, eject the liquid in a pattern towards an external surface of the base member.

Abstract: A device and a method for ejecting a fluid are provided. The device comprises a main pipe, a rotatable housing connected to the main pipe and a hub provided with a nozzle. The hub is rotatably connected to the housing. The fluid is arranged to be conveyed through the main pipe and the housing to said nozzle for ejection of the fluid, and the hub is arranged to rotate about an axis arranged with an angle ? in relation to a longitudinal axis of the main pipe. The angle ? between the axes is arranged to vary between 90?? and 90+?, 2???45, when the housing rotates one revolution.

Abstract: A device and a method for continuous and adjustable dosage of fluids at low pressure. The invention is self-cleaning and low tech. It consists of a tapering dosage unit in which a filling, which allows fluids to pass in the longitudinal direction of the dosage unit, is inserted. At the outlet end of the dosage unit, a venturi tube is located which clamps the filling and thereby create a nozzle opening that fits the fluids viscosity and the pressure for a given desired dosage. When the dosage unit clogs, a flushing can be obtained by either increasing the pressure of the fluid and thereby forcing a flexible dosage unit to increase the sectional area and allow cleaning or in the same way through a mechanical opening of the dosage unit.
