Definitions

  • the object of the invention is a method and set for cleaning surfaces, especially surfaces of electrical devices being under voltage.
  • a cleaning device consists of vertical fan-filtering system put in electro-insulating case, a dust container and an insulating carriage with an insulating handle.
  • the dust container is connected to a sucking device ended with a brush by means of a sucking and electro-insulating hose and electro-insulating sucking tube.
  • a washing device is a brush with a body having symmetrically drilled sucking holes put between double tufts of bristle on its whole surface connected favourably permanently with the insulating pipe.
  • a compressor is connected by an insulating pressure hose to a check valve of a liquid container, and in turn an outlet of the liquid container, connected with a diffuser touching a bottom of the liquid container, is connected to insulating pressure hose with insulating airbrush.
  • this method is very time-consuming.
  • the abovementioned methods of cleaning require mechanical contact with electric devices what may cause its damage.
  • This method cannot be used for cleaning electric elements under voltage, because after contact with the cleaned surface, the cleaned surface is water-wet.
  • a method of cleaning surfaces, especially surfaces of electric devices under voltage in which, using dry ice method, a stream of compressed air is applied onto a cleaned surface at a safe distance.
  • the method according to the invention characterises in that compressed air is dried to humidity of 0,008 - 0,0002 g/m 3 and next is passed through a container with dry ice having the temperature from -70°C to -30°C and granulation 1,5 to 5 mm. Drying of the compressed air before supplying it to a dispensing device of dry ice prevents wetting of the cleaned surface, therefore it enables electric devices under voltage to be cleaned with this method.
  • a set for cleaning surfaces comprises a nozzle embedded on a lance connected with a hose with the dry ice dispensing device and a compressor producing compressed air.
  • the set characterises in that between the compressor and the dispensing device of dry ice there is mounted a dehumidifier of the compressed air. It is connected with the compressor by a hose and another hose with the dispensing device. It is very advantageous to put the compressor and the dehumidifier in a thermally insulated container. Mounting the insulated container comprising the compressor and the dehumidifier together on a vehicle makes the set easy to remove to places needed to be cleaned, such as switch-rooms, transformer stations, production lines, buildings.
  • Fig. 1 shows a set for cleaning surfaces.
  • a compressor 2 is mounted connected by a hose 3 with a dehumidifier 4 of compressed air. Mounting the container on a chassis makes a set mobile. Dried compressed air is delivered by a hose 5 to a device 6, which contains dry ice. The device has a control panel 7 which controls quantity of pressure or pressure level of the compressed air and the amount of dry ice. From the device 6 there is a hose 8 connected with a lance 9 ended with a nozzle 10, from which the cleaning agents gets out. The arrows show the direction of the air and cleaning agent flow.
