Abstract

The invention can be used in electrode fluid heaters. The purpose of the invention is to increase the reliability of the steam generator. The hermetic chamber of heating of the steam generator with its lower part is connected to the supply tank 2 and has a pair of vertical electrodes 3 and 4. The zero electrode 3 is made in the form of a perforated hollow cylinder coaxially covering the phase electrode 4 with the formation of an annular interelectrode gap 5. The lower part of the chamber 1 is separated from the upper a transverse partition 6 adjacent to the lower edge of the electrode 3 and made against the gap 5 with openings 7, communicating the lower cavity of the chamber 1 with a gap 5. The use of electrodes and partitions allows to intensify the liquid flow in the gap 5 and provide sludge removal from the gap. 1 il. i (L

The invention relates to industrial heat engineering and can be used in electrode heaters for liquids.

The purpose of the invention is to increase the reliability of the steam generator by intensifying the removal of sludge from the electrode gap.

The drawing shows a steam generator, a longitudinal section.

The steam generator contains a sealed heating chamber 1 connected to the bottom of the supply tank 2 and provided with at least one pair of vertical electrodes 3 and 4. The zero electrode 3 is made in the form of a perforated hollow cylinder coaxially covering the phase electrode 4 with the formation of an annular electrode gap 5. Bottom part of the chamber 1 is separated from the upper transverse partition 6, adjacent to the lower edge of the zero electrode 3 and opposite the interelectrode gap 5 with openings 7, communicating the lower awn chamber 1 with a gap 5.

The heating chamber 1 is connected to the capacity 2 of the pipeline 8, the flow area of which is larger than the total area of the openings of the holes 7, and communicated with the steam consumer by the fitting 9, and in its lower part has a hatch with a crack 10 to remove sludge. During the operation of the steam generator, water from the feed tank 2 enters the bottom of the chamber 1 and through the openings 7 into the interelectrode gap 5, where it is heated and through the perforated wall of the zero electrode 3 in the form of a steam-water mixture enters the upper part of the chamber 1.

When the steam consumption on the consumer line decreases, the pressure in the upper part of the tank 1 pulls out and the water through the openings 7 and pipeline 8 is displaced into the tank 2, this leads to an intensive flow of water in the interelectrode gap 5 and the sludge is transported to the lower part of the chamber 1, from which the sludge can be removed through the hatch with the lid open 10.

The use in the steam generator containing coaxial tubular electrodes 3 and 4 of the transverse partition 6 makes it possible to intensify the fluid flow in the interelectrode gap 5 and remove the sludge from there, which ensures reliable operation of the steam generator.
