Definitions

  • the invention relates to a method for cleaning the inside of a tank, in particular crude oil tanks, in which a cleaning vehicle introduced into the interior of the tank is moved by a motor on the tank bottom.
  • the invention further relates to a cleaning vehicle provided for this purpose.
  • Such a method and cleaning vehicle are known from US 5 640 982 A.
  • Larger quantities of crude oil are usually stored in large crude oil tanks with a capacity of 100,000 m 3 and more.
  • Such crude oil tanks can be designed, for example, as floating roof tanks, in which a disc-shaped roof floats on the crude oil and can move up and down in the vertical direction when there is an inflow or outflow of crude oil in a jacket of the floating roof tank.
  • deposits form on the bottom of such crude oil tanks, which are formed by the sinking of heavier constituents of the crude oil and are often referred to as "gatch".
  • the deposits often have a sediment-like firm consistency and a comparatively slippery surface.
  • the type and thickness of the deposits depend, among other things, on depends on the type of crude oil stored, the quantity stored, the turnover rate and the tank size.
  • the deposits must be removed at regular intervals, for which purpose the crude oil is generally first drained off and then the deposits are removed mechanically from the tank bottom. This work is usually carried out by cleaning personnel, who must wear full protective clothing and breathing apparatus due to the health-damaging conditions inside the tank. In order to dissolve the deposits, hot water or a cleaning solution is often sprayed onto the deposits. Depending on the consistency of the deposits, it may also be necessary to mechanically, e.g. with shovels to detach from the bottom of the tank.
  • cleaning vehicles As a replacement for this heavy and dangerous work inside the tank, cleaning vehicles have been proposed, which are mostly robot-like tracked vehicles.
  • a cleaning vehicle is known from US Pat. No. 4,817,653 A, which, in the disassembled state, is introduced into the interior of the tank via a side manhole and assembled there. Since flammable gases may be present inside the tank, this known cleaning vehicle is driven exclusively hydraulically.
  • the cleaning vehicle is controlled by an operator in the interior of the tank with the aid of a control unit hydraulically coupled to the cleaning vehicle. Water can be applied at high pressure to the tank bottom to loosen the deposits by means of a nozzle which is movably arranged on the cleaning vehicle.
  • This known cleaning vehicle also has the possibility of absorbing and pumping off the liquid collecting on the tank bottom. For this purpose, the cleaning vehicle is connected to a mobile supply unit parked outside the tank via hose lines.
  • Another cleaning vehicle known from US Pat. No. 5,640,982 A can be folded up by means of a joint mechanism in such a way that it can be introduced into the interior through the relatively small manholes of such tanks without prior disassembly.
  • the cleaning vehicle carries a video camera and can thus be controlled by an operator who is located outside the tank.
  • a lamp is also mounted on the cleaning vehicle to illuminate the interior of the tank.
  • this object is achieved in that at least one pulling element connected to the cleaning vehicle is fastened to a stationary part of the crude oil tank, and in that the cleaning vehicle causes its movement on the tank bottom or at least assists it with motor power which pulls at least one tension element.
  • this task is performed by at least one on the cleaning vehicle arranged pulling device solved, which acts on a fixed part of the crude oil pulling element that shortens the clear length of the pulling element between the fixed part and the pulling device when the pulling device is actuated and thereby moves the cleaning vehicle on the tank bottom or at least supports locomotion.
  • the cleaning vehicle according to the invention can itself via the pull element fixed to the crude oil tank pull the bottom of the tank.
  • the tension element With appropriate attachment of the tension element to the stationary part of the crude oil tank and with a sufficiently high tensile strength of the tension element, the forces that can be used for propulsion are essentially limited only by the tension device arranged on the cleaning vehicle, with which the clear length of the tension element is shortened, thereby thereby to achieve a forward movement.
  • the movement of the cleaning vehicle can also be effected exclusively with the aid of the pulling element, so that a separate drive for the chassis of the cleaning vehicle can be dispensed with. In most cases, however, it will be cheaper to provide the cleaning vehicle with its own drive acting on wheels or chains in order to enable the cleaning vehicle to be maneuvered independently of the pulling element.
  • the pulling device then only acts as a support for the propulsion of the cleaning vehicle and can also be temporarily switched off completely if the cleaning vehicle is moving, for example, in an area with a well accessible surface. Since the traction device is arranged on the cleaning vehicle itself and not on the opposite side of the traction element, only a part of the entire tank interior, namely the cleaning vehicle, has to be equipped with suitable drives, for example a hydraulic motor.
  • the cleaning vehicle can thus move autonomously in the tank interior without the need for several drive components to be coordinated and arranged at different locations. Since the cleaning vehicle according to the invention only requires an additional pulling device, it can, like the already known cleaning vehicles, be constructed very compactly, so that it can be disassembled outside the tank in a few simple steps and can be easily assembled again inside the tank. It is also possible to design the cleaning vehicle to be foldable in such a way that it can be inserted into its interior through a manhole in the wall of the crude oil tank in the folded state.
  • the cleaning vehicle Since the interior of the tank in floating roof tanks is relatively jagged by the floating roof supports, the cleaning vehicle cannot be maneuvered arbitrarily over the tank bottom in such tanks. However, since the floating roof supports are generally distributed regularly over the interior, the cleaning vehicle can be guided through alleys that remain between the floating roof supports. After such an alley has been completely cleaned, the at least one tension element can be removed and moved in such a way that the Cleaning vehicle can now continue its work on a neighboring alley.
  • the tension element can in principle be attached to any fixed part near the tank bottom.
  • the fixed part is preferably a tank wall or a tank bottom of the crude oil tank.
  • the tension element is therefore fastened to the tank wall with the aid of a permanent magnet.
  • This type of attachment of the tension element to the tank wall is particularly simple and also very secure, since no measures are required for this, which may lead to a local heating or even sparking. If the tension element is fastened to the tank wall with several individual permanent magnets connected to one another by means of rope pulleys, each individual permanent magnet can be detached from the tank wall without additional aids, and yet a high holding force is achieved overall by the permanent magnets. However, the permanent magnet or magnets can also be provided with suitable cutouts which enable the permanent magnets to be lifted off with the aid of a tool.
  • the at least one tension element can also be attached to the tank bottom of the crude oil tank.
  • the cleaning vehicle can then no longer pull itself up to the tank wall itself, but fastening the traction element is particularly simple because, for this purpose, for example, only a snap hook attached to the traction element, etc. is required.
  • the tension element itself can be designed in a variety of ways.
  • it can be a toothed belt that can withstand high tensile loads, which can be shortened in its internal length by a toothed drive integrated in the pulling device.
  • the pulling element can even be a linkage that can be loaded not only under pulling but also under pressure, so that the cleaning vehicle can not only pull along the pulling element, but can also "repel" from it.
  • the at least one tension element is a rope.
  • the pulling device can then be designed as a cable winch which is arranged on the cleaning vehicle and ensures that the clear length of the pulling element between the stationary part and the pulling device is shortened when the cleaning vehicle is moving.
  • Ropes also have the advantage that they are mechanically very robust and their function due to contamination o. is not significantly affected.
  • the cleaning vehicle can not only pull itself to a certain point, but can also move back and forth by reciprocal pulling on the opposing pulling elements, even without the use of any chassis drive that may be present.
  • the cleaning vehicle can be freed again at any time by pulling in the backward direction, without the need for operating personnel to enter the interior of the tank. If four traction elements are arranged in a cross shape to one another, the cleaning vehicle can not only move back and forth between two opposite fastening points, but - after a 90 ° rotation of the running gear - can also move in a direction perpendicular to this or in any intermediate direction by exerting a tractive force ,
  • traction elements instead of several individual traction elements, a smaller number of traction elements can of course also be used, which then run through or past the cleaning vehicle. The pulling element is then not caught up, but the cleaning vehicle pulls along the continuous pulling element in one of the two directions. This can be realized particularly easily, for example, if the pulling element is a toothed belt, because then the pulling device can consist, for example, only of a driven toothed wheel which engages the continuous toothed belt.
  • a particularly rapid and effective cleaning of the tank interior can be achieved in particular by combining a plurality of cleaning devices.
  • a cleaning device can be implemented, for example, as a suction device for sucking off crude oil deposits.
  • the cleaning vehicle itself is able to pick up the released deposits and to transport them to a location outside the crude oil tank.
  • the crude oil tank then does not have to have drains itself; nor are there any additional suction hoses required in the crude oil tank.
  • the vacuum required for suction can either be generated by the supply unit or by a suction pump, which is preferably hydraulically driven and arranged on the cleaning vehicle itself.
  • tank residues can be flushed onto the bottom of the crude oil tank. If necessary, heated heating oil is particularly suitable for this.
  • the cleaning vehicle has a platform which is arranged on a chassis of the vehicle so as to be rotatable about a vertical axis and which carries at least one cleaning device.
  • the cleaning vehicle can also perform cleaning work on both sides and even behind it, even if it only moves in one direction over the tank bottom.
  • such a platform has the advantage that, in particular when several cleaning devices are arranged on it, they are always pivoted together on the platform.
  • the suction device is preferably arranged on the platform such that it can be displaced in the horizontal direction.
  • the suction device can now be guided both by rotating the platform and by moving it over a larger floor area surrounding the cleaning vehicle in order to clean it in this way.
  • the cleaning vehicle has a clearing means which can be displaced in a force-actuated manner relative to a vehicle body.
  • a power-operated adjustable broaching means enables particularly stubborn deposits to be loosened mechanically from the tank bottom without the cleaning vehicle having to be moved back and forth as a whole. If, according to the invention, the cleaning vehicle is braced against stationary parts of the crude oil tank by means of one or preferably a plurality of tension elements, higher mechanical forces can also be exerted on the deposits due to the now particularly high stability.
  • the broaching means is preferably part of the suction device, e.g. a suction hood.
  • a cleaning vehicle designed in this way can be operated like a clearing vehicle which mechanically loosens deposits with the extraction hood and at the same time sucks off the loosened pieces.
  • Mechanical detachment of deposits is particularly effective if the clearing agent is moved back and forth independently of the vehicle movement.
  • the cleaning vehicle has a screw pump which has an inlet pointing to the bottom of the crude oil tank.
  • a screw pump of this type it is also possible to pick up and vacuum off coarser deposits which, because of their size or weight, cannot be picked up directly by a suction device.

  • a video camera is arranged on the cleaning vehicle.
  • the interior of the tank can either be illuminated by lights installed there or also by a spotlight arranged on the cleaning vehicle itself.
