Extended reach sluicer systems, devices, and methods for breaking up and retrieving chemical, radioactive, hazardous materials and/or other waste from storage tanks, with mechanical arms and nozzles which utilize fluid jets to break up and liquefy in-tank material. The invention can work with tanks having additional issues, such as but not limited to high temperature or low temperature conditions. An upper assembly attachable to a tank can control the transverse rotation of a vertical mast and with a lower end pivotally attached to a boom having a nozzle assembly attached to an outer end. The boom can telescopically retract and extend to different length positions by cables and pulleys. Controls with take-up mechanisms can elevate up and down or transverse left and right the nozzle assembly.

A crude oil storage tank includes a bottom wall, a peripheral wall and a top wall that collectively define a storage volume. A first nozzle is arranged at the peripheral wall. The first nozzle is configured to selectively rotate between a first position and a second position to direct a first stream of fluid into the storage volume. A second nozzle is arranged at the peripheral wall. The second nozzle is configured to selectively rotate between a first position and a second position to direct a second stream of fluid into the storage volume.

An oil tank cleaning device is used to solve the problem of poor effect of conventional cleaning operation of an oil tank. The oil tank cleaning device includes a separation equipment, a temporary storage tank, a collecting tank, a pipeline unit, and a plurality of control valves. A first pump sucks air out of the temporary storage tank, such that the temporary storage tank is in a negative pressure state. The collecting tank receives a fluid outputted from the temporary storage tank. The pipeline unit includes a plurality of pipes for intercommunicating with an oil supply tank, a to-be-treated oil tank, the temporary storage tank, the separation equipment, and the collecting tank. Each of the plurality of pipes includes at least one of the plurality of control valves. Each control valve is configured to control flow of a liquid in the control valve.

A liquid cannon for use in discharging a liquid. The liquid cannon has an inlet for the liquid and a conduit providing a flowpath for the liquid between the inlet and at least one nozzle. The liquid cannon includes a head assembly having a turret supporting the at least one nozzle. The conduit passes through a bearing rotationally supporting the turret relative to a mount.

In one example there is disclosed, an apparatus (10) for vacuum cleaning a tank (11). The apparatus (10) includes a main body (12) coupled to a working arm (14) and a plurality of support legs (16) coupled to the main body (12). The main body (12) includes a main conduit (40) extending lengthwise therethrough and a common central actuator (32) fitted about by the main conduit (40). The working arm (14) includes a vacuum conduit (50) in fluid communication with the main conduit (40). The plurality of support legs (16) are operatively coupled to the common central actuator (32) so as to be simultaneously moveable at least between a collapsed condition so as to fit through an opening 18 of the tank 11, and an extended condition in which the plurality of support legs (16) are moved relatively outwardly so as to be telescopically extendable within the tank (11) to engage a side wall (20) of the tank to support the main body (12). Other examples of the apparatus, a system and related methods are also disclosed.

A cleaning system includes a cleaning apparatus that is positionable in a cleaning environment and a cleaning processing device. The cleaning apparatus includes a sensor and a cleaning device. The sensor is configured to measure a depth of a target material on a surface of the vessel, and the cleaning device is configured to generate a cleaning force. The cleaning processing device is configured to receive a plurality of depth measurements of the target material on the surface, determine a cleaning protocol for the cleaning device on the surface based on the plurality of depth measurements, and control the cleaning apparatus to cause the cleaning device to apply the cleaning force to the surface pursuant to the cleaning protocol.

A collector includes one or more air/oxygen/gas introduction ports to form a bubbler that produces curtains of air/oxygen/gases into the waterway. The bubbler can be integrated into the collector, or formed as a separate component used with or without the collector. First and second pumps provide for improved removal of sediment collected in the collector cavity.

A stormwater vault and a process for servicing the stormwater vault speeds the process of cleaning the stormwater vault. The stormwater vault has a built in liquefaction system for liquefying settled debris in the vault which works together with a sloped or angled floor in the vault and vertical debris cutting spray nozzles. The settled debris is flushed toward the inlet to a vacuum removal line inserted into the vault through an access opening for removing the settled debris from the vault while compacted debris is collapsed by vertically extending water nozzles.

A siphon is adapted for thoroughly cleaning fluid vessels. The siphon is capable of elevating discharge waste fluid through a transfer of kinetic energy provided by a pressurized fluid source, thereby obviating any need for undesirable electrical, chemical, or other mechanical power sources. An inlet couples pressurized fluid to a divider that splits the pressurized fluid between a jet port outlet and a tank flush source conduit. A siphon return conduit is operative to carry waste fluid from the fluid vessel, with the cleaning attachment protruding from the siphon return conduit. By slightly protruding, the cleaning attachment operatively blocks the siphon return conduit from being held by siphon vacuum against a surface of the fluid vessel while developing a beneficial eddy current flow path. A drain conduit is provided, as is a mixing chamber at a junction between the jet port outlet and an outlet from the siphon return conduit.

A system and an associated method for starting up stirring machines in a sediment in a controlled manner are provided, which system has the following: a container for receiving materials to be processed; a stirring device with stirring blades for stirring the materials to be processed in the container; a purging device; and a device for operating stirring machines. The purging device is arranged in such a way and set up so as to feed a medium for purging to a deposited sediment. Furthermore, a controller is provided which initiates controlled re-starting of stirring machines after purging.
