The present invention provides a cleaning method and equipment thereof for object FOUP, comprising the following steps: firstly separating the object FOUP into a container lid and a container body, then conducting individual processes of wet washing, liquid removing and vacuum drying for the container lid and container body, and in the end combining the container lid and container body to complete the cleaning procedure of the object FOUP; specifically, during the liquid removing process, multiple wind knives are used to carry out liquid removing for the container body, and during the vacuum drying process after liquid removing, multiple thermal components are used to carry out vacuum drying for the container body under a vacuum environment; moreover, the present invention also includes the cleaning equipment to execute the above method, for the purpose of overcoming the problem that the wet cleaning process in the conventional automatic chip FOUP cleaning technique cannot effectively clean object FOUPs with relatively complicated internal structures.

A method of cleaning a concrete bowl is provided including the steps of a) introducing water into at least one concrete bowl; b) collecting the water from the bowl after it has been used; and c) cleaning a concrete bowl by introducing at least some of the collected water into the bowl under pressure.

A method and apparatus for cleaning, and removing contaminants from the interior of a lubrication rundown tank of a mechanical system provides a source of pressurized and heated cleaning fluid containing at least one solvent; a first jumper hose communicating between the source of pressurized cleaning fluid and the interior of the lubrication rundown tank; a second jumper hose communicating between the interior of the lubrication rundown tank and a dirty fluid collection body; and an outlet spray nozzle carried by a nozzle extension placed within the interior of the lubrication rundown tank and in fluid communication with the source of pressurized and heated cleaning fluid to receive the pressurized and heated cleaning fluid therefrom.

Systems and methods are disclosed for inspection, maintenance, debris removal, and cleaning of environments that may be difficult to access and hazardous. The system comprises a mast assembly, an arm assembly, a debris removal system, and a drive system. The mast assembly comprises an inner mast and an outer mast having a central axis about which the arm assembly revolves. The arm assembly provides support for the debris removal system. The debris removal system comprises a bucket tool, a plow tool, and one or more hoses for clearing and removing debris. The drive system comprises a plurality of one or more of cables, pulleys, rollers, and hoists to at least one of control motion of the arm assembly, raise and lower the inner mast, and position and control at least one of the bucket tool and the plow tool. The system is at least one of manually and automatically controlled.

A tank cleaning machine comprising a housing having an inlet and a stationary guide diverter disposed within the housing. A gearing mechanism is attached to the stationery flow diverter. A nozzle extends from the housing wherein the nozzle is in fluid communication with the inlet and the nozzle includes an inclined portion extending from a horizontal portion of the nozzle. A drag limiter extends into a hydraulic fluid reservoir to limit the rotation speed of the gear.

A water washing method and system for a crude oil tank. The water washing method includes inputting washing water into the crude oil tank; injecting high-pressure water to the lower portions of the crude oil tank such that the sludge mixes with the washing water; and discharging mixture water in which the sludge is mixed with the washing water from the crude oil tank.

A cylinder head cleaning method capable of cleaning a cylinder head with an enhanced foreign matter removing rate. The method is used to clean a cylinder head (1) having therein a water jacket (15) including a narrow space portion (Z) having a narrow flow path and a large space (Y) having a flow path wider than the narrow space portion (Z), and the cylinder head (1) further having holes (12A-12R, 13, 14, 16A-16C) communicating with the water jacket (15). Cleaning nozzles (28A, 28C) are inserted into the water jacket (15) from the holes (16A, 16C) selected from the holes (12A-12R, 13, 14, 16A-16C), clearing liquid is ejected from the cleaning nozzles (28A, 28C) toward the narrow space portion (Z), and the cleaning liquid flowing from the narrow space portion (Z) to the large space (Y) is discharged to the outside of the cylinder head (1) from the hole (16B) communicating with the space (Y).

An apparatus, system and method for removing and treating contaminated materials on a bottom of a body of water and introducing growth packets to revitalize the treated bottom of the body of water. The structure may comprise a vessel with an open face. The vessel may be lowered down to the bottom of the body of water with the face facing down. As a result, the vessel and the bottom form an isolated space. The structure may comprise at least one agitating device(s) for stirring up the materials inside the vessel so as to form a mixture containing the sediment materials which in turn contain the contaminants. Multiple at least one pipe(s) may be coupled to the vessel for transporting the mixture out of the vessel for processing (filtering, treating with chemicals, etc.) so as to neutralize or eliminate the contaminants in the mixture. Then, the treated mixture can be returned to the inside of the vessel via the at least one pipe(s).

Provided is a method for removing deposited solid residue from equipment used in the processing of (meth)acrylic acid or esters, including the steps of dissolving the solid residue in a cleaning solution comprising an organic carboxylic acid to produce a solid residue slurry; and removing the solid residue slurry from the equipment.

A system includes a skip, a first sensor and a conveying section. The skip includes a hollow interior to store solids therein. The skip further includes an inlet and an outlet. The first sensor is located adjacent the inlet to indicate that the interior is filled with solids up to a predetermined level. The conveying section is located downstream of the outlet and is in solids communication with the interior. After the first sensor indicates that the interior is filled with solids up to the predetermined level, the conveying section conveys solids away from the skip and the skip is emptied. A method of using the aforementioned system is also disclosed.
