A spraying system and method is provided for more efficiently accessing the interior of a container having an access opening to the container that is offset from or in angular relationship to the center and/or rotational axis of the container to contact the interior walls and surfaces of the container with a medium, such as a liquid, mixture, solution or suspension. The spraying system and method includes a non-linear boom that is elevated by a support structure, where the non-linear boom includes at its front end a plurality of spray nozzles. In one example, the support structure is a movable support structure that includes a guide mechanism where the guide mechanism is mounted on the moveable support structure at an angle relative to the surface supporting the moveable support structure to allow access to the interior of the container.

A misting fan includes a nozzle, a fan assembly, and a support assembly. The nozzle is configured to spray water. The support assembly is formed with a coupling portion for detachably coupling a battery pack. The nozzle is disposed on the fan assembly or the support assembly and includes a nozzle body and a second part. The nozzle body includes a first part formed with a first surface and the second part is detachably installed to the nozzle body and formed with a second surface. When the second part is installed to the nozzle body, a water flow channel is formed between the second surface and the first surface. When the second part is detached from the nozzle body, the first surface is at least partially exposed for cleaning access.

The application provides a disinfecting device. The device comprises an aircraft trolley-sized body comprising two side surfaces. The body is adapted to move along a longitudinal axis of an aisle of an aircraft such that the side surfaces face two opposing sides of the aisle. The device includes a powering unit, at least one air compressor for providing compressed air, a disinfectant bottle for storing liquid disinfectants, and at least two nozzle assemblies. Each nozzle assembly includes an electrically actuated valve, a connector, and at least three nozzles. The compressed air flows from the compressor to the valve, to the connector, and to the nozzles to form droplets of disinfectants. The nozzles are provided on upper surfaces of the body such that the nozzles point away from the respective side surfaces for spraying the disinfectants onto objects located on the two opposing sides of the aisle.

A method of processing a substrate may include preparing the substrate, polishing the substrate, and cleaning the substrate using a double nozzle, which is configured to provide a spray and a chemical solution onto the substrate. The spray may include a deionized water, and the chemical solution may be diluted with the deionized water. The chemical solution and the spray may be spaced apart from each other by a distance of 7 cm to 12 cm.

A nozzle apparatus includes a manifold defining a nozzle cavity within an interior, a fluid inlet passage, a fluid outlet passage, an air outlet passage, and an air inlet passage. A nozzle holder and a nozzle element are selectively pivotable within the nozzle cavity. In the nominal position, the nozzle element inlet is oriented toward the fluid passage inlet and the nozzle element outlet is oriented toward the fluid passage outlet such that the primary fluid flows through the fluid inlet passage and out of the nozzle outlet through the fluid outlet passage. In the cleaning position, the nozzle element inlet is oriented toward the air outlet passage and the nozzle element outlet is oriented toward the air inlet passage such that the flow of air is directed through the air inlet passage, and out of the air outlet passage to direct debris out through the air outlet passage.

A method of actuating a double-action pump assembly with a reciprocating plunger includes signaling the reciprocating plunger to stop for a changeover period; while the pump is stopping, signaling the first inlet and outlet valves to close; while the first inlet and outlet valves are closing, signaling the second inlet and outlet valves to open, such that the second inlet and outlet valves begin to mechanically open at least a dwell period after the first inlet and outlet valves have entirely closed; and signaling the reciprocating plunger to begin moving while the second inlet and outlet valves are closing.

A method of controlling a concentration or range of concentrations of a liquid or gas in an enclosure is provided. The method includes positioning an injection station within the enclosure, the injection station includes a liquid or gas source, a sprayer assembly and a system that delivers the liquid or gas from the liquid or gas source to the sprayer assembly. A concentration level of the liquid or gas in the environment surrounding the injection station is monitored using a sensor and the sensor providing a signal indicative of the concentration level to a controller. The controller controls the flow of the liquid or gas to the sprayer assembly based on the signal.

A nozzle lance for exhaust gas treatment, a combustion plant with nozzle lances for exhaust gas treatment and a method for exhaust gas treatment in a combustion plant are proposed, wherein an admixing fluid is admixed to the active fluid in the nozzle lance and atomized via three nozzles.

A treatment system for spraying treatment fluid onto plants in a field is described. The treatment system includes a highly configurable treatment mechanism including an array of nozzles and valve assemblies coupled into manifolds, and manifold assemblies. The manifolds of the manifold assemblies can be oriented in an open state or a nested state, the open state with no overlap between nozzles of adjacent manifolds and the nested state with overlap between nozzles of adjacent manifolds. The manifolds can have multiple configurations, examples of which include a tube manifold and an offset manifold. The nozzles of the system can have multiple configurations, examples of which include a tri-spray nozzle, a bar nozzle, a fan nozzle, and a deflected fan nozzle. The system can be controlled by a system controller which detects plant material and instructs a nozzle or combination of nozzles to spray treatment fluid.

Disclosed is an improved vehicle reservoir system for managing the distribution of applicable fluids, including either liquids or gases individually, simultaneously, or a combination of these in a predefined sequence. In one embodiment, a first reservoir contains a non-pressurized fluid that is transferred to a distribution manifold and a second reservoir contains a pressurized fluid that can be transferred to the distribution fluid for admixing with the first reservoir fluid, or to a second distribution manifold, or a combination thereof.
