Definitions

  • the invention relates to a propeller agitator for stirring crude oil stored in a large tank, with a propeller that has a hub and several propeller blades.
  • Such a propeller agitator is from DE 44 28 050 A1 known.
  • Larger quantities of crude oil are usually stored in large tanks with a capacity of 100,000 m 3 and more.
  • Large tanks of this type 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 the large tank, which result from the sinking of heavier constituents of the crude oil and are referred to as "Gatch".
  • the type and strength of the deposits depend, among other things, on the type of crude oil stored, the quantity stored, the turnover rate and the tank size.
  • the propeller agitator known from DE 44 28 050 A1 mentioned at the outset can either - as just described - from above extend vertically into the interior of the tank or but in a horizontal position by one in the jacket of the large tank provided connector to be inserted into the large tank.
  • the Propeller agitator has a swivel through which the position the propeller axis can be changed.
  • one Lifting device provided, by means of which the distance between the propeller and the one in the roof or jacket of the tank Manhole or nozzle can be adjusted. To this The spatial range of action of the propeller agitator can be varied can be adjusted from the outside, causing the stored crude oil can stir more effectively and thus faster.
  • the adjustability of the wing pitch can, for example made possible by a suitable locking mechanism in the hub become.
  • the propeller blades are then inserted into the hub the desired position before the propeller agitator is introduced into the large tank.
  • the propeller has an operating mechanism that it allowed the pitch of the propeller blades from the outside during the operation of the propeller agitator.
  • the propeller agitator at least an actuator for adjusting the propeller blades having.
  • an adjustment of the wing pitch can not only from the outside of the large tank directly at the propeller agitator, but also from a distance using a suitable one Remote control can be made. This eliminates the need Operators who come out of the tank openings rising gases only in full protective clothing the propeller agitators may approach with the adjustment of the wing pitch entrusted directly to the propeller agitator.

  • the wing pitch is dependent on the control device controllable by the propeller speed.
  • this control is carried out in such a way that the wing pitch the lower the propeller speed, the lower is because this indicates a high viscosity of the crude oil. Accordingly, in the reverse case, i.e. at a high Propeller speed, a larger pitch from the control device specified.
  • the control device can also act as a control device be executed, the controlled variable the propeller speed and whose manipulated variable is the wing pitch.
  • an evaluation device which, based on the propeller speed, the pitch of the wing and the power consumption of a propeller drive a measure of the viscosity of the surrounding propeller Crude oil determined.
  • An image of the viscosity conditions inside the tank enables to control the stirring of the crude oil even more precisely. For example, if it is found that in a particular Tank area the viscosity of the crude oil greater than in the rest Areas of the large tank can be added early Propeller agitators introduced in this area or propeller agitators can be reassembled from other areas. Also allowed the determination of the viscosity conditions inside the tank a more precise time estimate of how long the stirring up of crude oil still has to be continued. On the job Previously used dipsticks, from above into the tank interior be introduced to increase the extent and strength of the deposits can determine all or part of it to be dispensed with.
  • Such an evaluation device is also in such a way Propeller agitators can be used advantageously, where none adjustment of the wing pitch provided according to the invention is.
