摘要:
An apparatus for treating a surface bounding a space within which a bulk supply of flowable material can be contained. The apparatus has an elongate support with a proximal region and a distal region. At least one flexible tube is provided at the distal region of the elongate support through which a fluid from a pressurized supply can be directed. The at least one flexible tube is movable continuously in a whipping action to thereby cause a force to be applied to a surface at or adjacent to which the flexible tube is located to thereby at least one of: a) apply a fluid; and b) separate matter adhered, to a surface at or adjacent to which the flexible tube is located. The apparatus further has a moving assembly for the elongate support. The moving assembly is operable to controllably reposition and/or reconfigure the elongate support, thereby to controllably place the at least one flexible tube at different selected locations with respect to a surface to be treated by the apparatus.

Systems for cleaning sludge from a large tank. The sludge from the interior of storage tanks is mobilized using a metered flow agent stream and then subjected to a mechanical comminution or high shear action, e.g. by grinding or chopping. This produces a pumpable slurry which is then recirculated back into the tank to further mobilize sludge.

Apparatus for remotely operated fluid pumping in work spaces, particularly suitable for the cleaning of enclosed space tanks such as those on marine vessels. The apparatus comprises one or more arm assemblies, each made up of two or more arm sections each, with the arm assembly mounted within of the tank. Hydraulic rotary actuators disposed between the arm sections provide up to 360 degree rotation of one arm section with respect to the next. A nozzle is mounted on a pair of hydraulic rotary actuators near the end of the arm assembly distal from the mount, with a hose supplying fluid from a supply pump to the nozzle. Fluids and solids from the cleaning operation can be pumped from the area being cleaned via a discharge pump to a holding vessel, such as a disposal barge. A video camera is mounted on the arm assembly, preferably at the nozzle, to permit an operator to remotely view the cleaning process and area. A control panel is preferably remotely located where an operator can fully control the device with the assistance of the video camera, including fluid flow, position of the arm assembly, and direction of fluid flow from the nozzle.

The present invention relates to a device for interior flushing of spaces in tanks or containers. At least one rotatable part (8) of a pipe (6, 8, 11) for the supply of flushing liquid (7) is provided in the space (2) and said rotatable part (8) has at least one flushing nozzle (9) for discharging jets (10) of flushing liquid. A driving or operating device (22) is provided to rotate said rotatable part (8) about a geometric rotation axis (R1A) and the flushing nozzle (9) about another geometric rotation axis (R2A). The driving device (22) is provided to be brought to rotate in opposite rotary directions (R1, R2) by reversing its rotary direction. A switch device (23) is provided to bring either said rotatable part (8) or the flushing nozzle (9) to rotate in dependence of the rotary direction (R1 or R2) of the driving device (22). A control device (48) is provided to control the driving device (22) to rotate in one or the opposite rotary direction (R1 or R2).

The present invention 10 discloses an improved device for cleaning the inside of vessels 12 which could include truck tankers or rail car tankers. The present invention discloses a generally vertically standing rotatable support member 24 having mounted thereon a parallel pair of lazy tong assemblies or configurations 22 being a series of jointed and pivoted bars or arms, e.g., 28, capable of being extended over a great distance. Mounted on the distal end of the lazy tong assembly 22 is a spray head 32 having multiple spray outlets 42 and being fluidly connected to a supply of cleaning liquid 18 located on the outside of the vessel 12 which is being cleaned. The fluid connecting means comprises a hose 16, 46 along with connecting members being either a rod or a milled shaft 52 having a pair of pivotal centrally located collars 54 having connection means 50 for a hose on each collar 54 and a conduit 68 within the milled shaft 52 creating a passageway between the collars 54 forming a fluid connection from one collar to the next and the spray head 32.
摘要:
A system for cleaning vessels that have been contaminated with oil field drilling and production waste materials such as oil well drilling fluid or hazardous waste using recycled wash water. As dirty wash water accumulates in a vessel during cleaning, it is transferred to a settlement section of the waste receiving barge. A cationic polymer is injected into the suction side of a waste water pump during transfer of dirty fluid from the vessel to the receiving barge. The polymers react with fluids to begin an initial settling process within the waste receiving barge. Decant water is subjected to secondary settlement and secondary chemical treatment after it leaves the primary settling section of the waste receiving barge. The laundered water is returned to the wash water storage facility for reusing and cleaning the same vessel or additional vessels. In this fashion, waste is continuously concentrated in the receiving vessel for ultimate disposal at a remote site and wash water is recycled for reuse.

The present invention relates to a flushing device for internal flushing of tanks, preferably tanks in vessels or ships, whereby a turbine wheel (13) in a turbine device (8) is mounted in a supply conduit (10) so that said wheel (13) is driven by the flow of flush liquid in said supply conduit (10), and whereby the turbine wheel (13) is provided to operate a driving assembly located outside the supply conduit (10) and provided to bring a flush-liquid pipe to rotate and at the same time revolve or turn flush nozzles (7). A magnetic coupling (50) is provided to transfer by means of magnetic power, the rotary motions of the turbine wheel (13) from the interior of the supply conduit (10) to the driving assembly (9) located outside said supply conduit (10). Furthermore, the turbine wheel (13) is displaceably mounted for increasing or decreasing the speed of rotation thereof.
摘要:
Method and apparatus for producing and recovering solvent vapor for cleaning the interior surfaces of substantially sealed vessels and the exterior surfaces of structures contained therein]. In the illustrated embodiment, a transportable vessel cleaning system is disclosed. The system comprises a plurality of solvent vapor producing chambers, each having a solvent vapor outflow port and a solvent vapor inflow port coaxially arranged along a vapor flow axis extending through each chamber along flow channels associated with the solvent vapor outflow and inflow ports. When operationally configured with a substantially sealed vessel, each solvent vapor producing chamber of the present invention produces a solvent vapor stream which is recirculated through the vapor delivery tube, vessel interior, vapor recovery tube and the solvent vapor producing chamber along the direction of its vapor flow axis. Each recirculating solvent vapor stream facilitates heat and solvent vapor fluxes between the solvent vapor producing chamber and the vessel interior which are sufficient to maintain saturated solvent vapor in the vessel at very high temperatures during cleaning operations.
摘要:
The disclosed cleaning method is carried out using a pressure vessel containing a cleaning liquid pumped out of the pressure vessel and into a dirty tank. Cleaning liquid and dislodged contaminants are sucked up from the dirty tank by a partial vacuum created above the cleaning liquid within the pressure vessel. Solids and cleaning liquid are pumped from the pressure vessel at a first rate and are separated by a solids separator with the cleaning liquid being centrifuged to remove fine solids and then collected in a makeup tank. Cleaning liquid from the makeup tank is pump into the dirty tank at a second rate, less than the first rate. Excess liquid in the makeup tank is sucked back into the pressure vessel. A phase separator, mounted beneath the suction inlet, speeds the separation and concentration of solids, liquids and gases/vapors. The phase separator includes a number of vertically aligned, downwardly and inwardly tapered truncated conical concentrators with open tops and open bottoms above and below the free surface.
