Description

The invention relates to the preparation of water for domestic and technical consumption, and in particular to devices for water disinfection.

The purpose of the invention is to improve the quality of water treatment and ensure the safety of the service of the device by utilizing the ozone generated

The drawing shows the device, a partial section.

The device consists of a housing 1 with inlet and outlet connections and a lid 2. A bactericidal lamp 3 is installed in a quartz glass case 4. The case can be made, for example, in the form of a flask, i.e. tubes with one end sealed. The electrical assembly of the lamp, consisting of a cartridge 5 and a power cable 6, is under the cover in the air space separated from the water in the housing by a seal 7. An ejector 8 is attached to the outlet nozzle. The internal cavity of the cover 4 is hermetically separated from the air space by a partition 9 which the tube 10 connects the cavity with the atmosphere, tube 115 is connected to the vacuum cavity of the ejector 8. The ends of the tubes 10 and 11 are lowered into the cavity of the cover to a different level, which creates a difference in height between the ends of the tubes ( p H), Size H is limited by the design dimensions of the protective cover 4 (its depth) and, in turn, by the size (length) of the germicidal lamp 3. Moreover, the larger the size H, the ciuibHee drawout effect, and, consequently, the higher the ozone yield other things being equal. With respect to the manufactured known lamps and covers, the size H is 500-900 mm.

The device works as follows.

When the lamp is on water, entrance to. device through the inlet.

discharge is generated. In case 4, ozone is formed from air. Through the tube 11, the ozone is sucked up by the ejector and mixed with the treated water. Through tube 10 from the atmosphere to

The cavity of the cover continuously flows all the time. The difference between the ends of the tubes 10 and 11 (size H) provides an additional effect to the ejector, like a chimney.

This achieves a more complete extraction of ozone from the air and the removal of ozone outside the cover. The ozone formed enters the treated water and disinfects it additionally. No ozone is released into the surrounding area. The process is continuous with the flow of water and the lamp is on.

To confirm the benefits

The proposed invention carried out comparative laboratory tests on the serial known OV-1P unit and the layout of the device proposed. The quality of the water disinfection is estimated by the indications of the coli index, the total number of microorganisms by known methods. Safety of service is assessed by the presence of residual ozone in the air of the enclosed area in which the checks are made. Fresh water that has been stored for a long time (about 2 May) in a hermetically sealed tank is subjected to disinfection (imitation of the ship’s storage conditions

water). The results of the checks are given in the table. .

The table shows that the proposed device provides improved quality of water treatment for bactericidal

ozone generation and utilization indicators, due to which the safety of the device maintenance is achieved.
