Definitions

  • the present invention falls into the class of devices for washing and cleaning of metal products - fuel tanks and other containers.
  • the subject matter of this invention is a transportable washer suitable for washing and cleaning of both fixed and portable fuel tanks-containers and falls into the sub-group C 236 5/04 of the International Patent Classification.
  • This device is an adequate substitute for similar imported devices and its manufacturing costs are very low as compared to the cost of such imported devices.
  • FIG. 1 The invention is illustrated with the enclosed drawing (Fig. 1) showing the structure of the "Dada” fuel tank washer, in particular:
  • filter corresponds to the switch in the collector tank (8)
  • 27 corresponds to the switch that turns the pump (17) on when the tank is empty (28) corresponds to the switch that turns the pump (17) off
  • (29) corresponds to the mixture (water, sludge, fuel) tank
  • the hot water producing unit (1) produces a required quantity of water at 150°C and, by means of the high pressure pump (2) having an output of 6300 1/h, the water pressure of 120 Bar is achieved.
  • the fuel (light oil) is supplied to the burner installed in the cleaning plant from a 3501 fuel tank (5) placed on a vehicle.
  • the hot water is pumped through the high pressure hose (21) to the interior washing heads (11, 12, 14, 16) of the gun (10) and to special self-propelled trolley (15).
  • the water degreases and washes the tanks, truck tanks and other containers.
  • a sludger (17) having an output of 65001/h is put into the tank, which pumps the mixture (sludge, water, fuel) through the hose (23) and delivers it to the tank (29).
  • the tank (29) is furnished with the switches (27, 28) designed to:
  • the sludger II (33), having an output of 24001/h, pumps the mixture (water, fuel, sludge) from the tank (29) into decanter-centrifuge (31).
  • the on/off switching of the sludger II (33) is performed manually.
  • the sludger ⁇ (33) is switched on when the sludger (17) starts to fill the tank (29) and is switched off when all the mixture (water, fuel, sludge) has been pumped out from the tank (29).
  • the decanter (31) separates the sludge from water and fuel.
  • the output of the decanter-centrifuge is 2400 1/h
  • the sludge is then discharged into the sludge tank (32), the mixture (water, fuel) is recirculated into the system, while the sludge is neutralized and safely disposed without any risk of environmental contamination.
  • the decanter-centrifuge (31) is switched on simultaneously with the sludge pump II (33).
  • the mixture (water, fuel) is pumped from the decanter-centrifuge (31) by means of the pump (34) and delivered to the super-centrifuge (18) having an output of 2400 1/h, where the heavier liquid is separated from the lighter liquid, i.e. petrol/oil from water in this particular case.
  • the petrol/oil is discharged in drums for further use and the waste water is either recirculated into the process through the collector tank (8) or discharged in the environment without any risk of environmental contamination.
  • the "Dada” washer may be used in the oil industry worldwide, in particular by all those involved in the transport, use and storage of oil and oil products, for the washing of truck tanks, underground tanks at filling stations, various fuel storage tanks from 1000 - 5000 m 3 and over, small containers (cans, drums) etc.
  • This washer is fully transportable and may be taken to any location where the cleaning-washing of a fuel tank is required. All component parts of the washer are preassembled in a container which is mounted on the body of a car or trailer. When out of use, the container is removed from the track with adequate lifting equipment, so that the truck may be used for other purposes.

Abstract

L'invention concerne un dispositif de nettoyage de réservoirs de carburant, transportable, destiné à être monté sur l'ouverture du réservoir de carburant ou sur un chariot autopropulsé. L'invention concerne également un procédé de nettoyage de réservoirs de carburant, consistant à évacuer le mélange (boue, eau pulvérisée, carburant) et à récupérer l'eau en la séparant dans une décanteuse centrifuge, pour la recycler ou pour l'évacuer sans contaminer l'environnement.
