DE2347826A1 - Ultra violet radiation water treatment unit - for sterilising water, esp. useful to swimming pools - Google Patents

Abstract

A unit for sterilising water, consists of two concentric cylinders and sealed at both ends w. r. t. each other. Water flows through a feed-pipe set tangentially at the top of the water cylinder into the annulus contg. a number of ultraviolet ray generators for effecting sterilisation of water. The air space in the inner cylinder also contains ultra-violet generators, to convert oxygen in the air into ozone the ozone being then fed, via a discharge pipe and a non-return value, into a water space discharge pipe where further sterilisation takes place before the water is returned to the swimming pool.

¹¹ Device for sterilizing water, especially swimming pool water "

The invention relates to a device for sterilizing water, in particular swimming pool water, by means of ultraviolet rays.

Of the various methods tried in practice, the water in the pool or the like. by rays too sterilize, only the method of contact irradiation is suitable, since this type of distance and reflection losses are avoided; but that means that the rays are only within that The volume of water flowing through the UV rays can be effective.

This is successful if the residence time of the water in the UV range, the entire circulation time and the intensity of the rays are matched to one another in a corresponding manner. One for However, the essential condition for success is that the water flow is designed in such a way that all of the water in the swimming pool actually flows through the UV radiation field once within the prescribed circulation time. In many, and mostly in larger, swimming pools, however, the water flow is so inadequate that there are so-called dead ones There are corners - these are amounts of water that are not included in the circulation and therefore never or only a high amount are seldom exposed to bactericidal rays, which is why bacteria and algae colonies form in the water impart undesirable properties.

The object of the invention is to provide a device for sterilizing To create water that prevents the formation of bacteria and algae colonies in an easier and safer way Way, the entire being in a swimming pool or the like Makes the amount of water germ-free.

This device should be simple and cost-saving, work safely and provide high performance.

With this device, a method is also to be carried out, which results in an optimal sterilization of the water and »with which the entire volume of water is treated while avoiding dead corners.

Geaaäss the invention is a device for sterilizing Ultraviolet water, in particular swimming pool water Jets, characterized in that one is closed on all sides, with an inlet and an outlet for water Equipped container with at least one arranged therein, the water sterilizing UV generator and one on all sides closed, with an inlet and an outlet for air aulgestattete container with at least one arranged therein,

A device (device) according to the invention for sterilizing water, in particular swimming pool water, by means of ultraviolet rays, has a container 12 which is closed on all sides and is equipped with an inflow Io and an outflow 11 for the water to be treated, and a second container 12 which is closed on all sides, with an inflow 13 and an outlet 14 for air-equipped container 15. In the receiving spaces 12a, 15a of both containers 12, 15 there is in each case at least one, and preferably a plurality of ultraviolet ray generators (UV generators) 16, 17 in each case. The UV generators 16 in the water tank 12 generate a UV radiation field with ultraviolet rays of bactericidal wavelengths; this with the water

coming in contact ultraviolet rays cause one Sterilization of the water.

The UV generators 17 in the air tank 15 also generate a UV radiation field in which the oxygen in the air turns into ozone is converted.

The outflow 14 of the air tank 15 is connected to the outflow 11 of the water tank 12 connected, so that the ozone escaping from the air tank 15 into the drain 11 of the water tank 12 penetrate and with the sterilized water through the drain 11 to its destination, the swimming pool or the like., can flow.

In a preferred embodiment, the air tank 15 is arranged in the water tank 12, namely arranged coaxially therein, so that the air tank 15 extends in the center of the water tank 12 and around it an annular space 12a for the Water in the water tank 12 forms. Both containers 12, 15 are sealed against each other and have a preferred Way the same height.

Both containers 12, 15 can have a circular, oval or polygonal basic shape and are designed to be cylindrical in the vertical direction.

On the outer water tank 12 is on the shell side in In the upper area (top area) a tangential nozzle is connected as an inflow Io and in the lower area (bottom area) there is a radial nozzle on the shell side as an outflow The inner air tank 15 has a fine upper Front wall l8, which is also the front wall for the Forms water tank 12, a vertical direction, preferably vertical stub al · air inlet 13 and from its lower, again equilateral the front wall of the The end wall 19 forming the water tank 12 is provided with a vertical, preferably vertical, connecting piece Oxon effluent / ab; these two connecting pieces 13, 14 run parallel or coaxial to each other.

The air tank outflow 1 ** is connected to the water tank outflow 11 by a connecting line 2o. It is preferred to use a check valve 21 in the connecting line 2o.

Furthermore, a multi-way valve 22 can be connected to the air tank outflow 14, from which on the one hand the connecting line 2o leading to the water outflow 11 and on the other hand an additional drain line 23 is connected; the Additional drainage line 23 enables ozone to be routed to certain areas in a swimming pool or the like, in particular into so-called dead corners or to another area of destination and use.

All UV generators 16, 17 preferably extend with their Length expansion in the height direction of the container 12, 15 and occupy almost the entire height of the container; the UV generators 16, are mounted in the top end wall 18, preferably held interchangeably and engage in the containers 12, 15 through openings within this end wall 18.

The UV generators l6 located within the water tank 12 and their electrical connections are radiolucent on one side (at the bottom). closed envelope or Schutsrohren 24 arranged (inserted) and are thereby protected from direct contact with the surrounding water without that the rays would be hindered from entering the water.

The rays generated by the UV generators arranged in the water space 12a have no ozone-generating emission spectrum - the emission spectrum of the UV generators surrounding the water concentrates in the bactericidal area.

In contrast to the UV generators 16 (emitters), the UV generators 17 located in the air space 15a of the inner container 15 have a different spectrum, namely an ozone-generating emission spectrum that does not necessarily have to be bactericidal got to.

In the air supply 13 on the top is an air conveying device, such as air pump.25, which pumps the air through the inlet 13 into the inner container 15. The electrical ones required to operate the UV generators 16, 17 Devices, such as ballasts, are housed in a control box on the container 12, the upper End wall 18, is arranged and covered by a hood. The total current consumption is measured by an ammeter, The failure is visible through an opening in the hood one or more UV generators 16, 17 is identified by different power consumption and is immediately visible displayed.

In a further embodiment, not shown, the two containers 12, 15 are arranged separately from one another and are only connected to one another by the connecting line 2o. One container 12 has the inflow and outflow 11, Io and the UV generators 16 for water disinfection and the other container 15 has the UV generators 17, the inflow and outflow 13, I ¹ * and the air pump 25. Both containers 12, 15 can be connected to a common frame or rack to form a structural unit.

It is also within the scope of the invention to use only the air tank 15 with its devices 13,1 ^ .2S, 17, 22,23 as a disinfection device to use.

The ozone formed in the air tank 15 is heavier (1,568 times heavier) than atmospheric air, thus sinks into the air container 15 downwards and can be discharged there through the outlet 14 and the water outlet 11 or, at the destination, zBdirekt into the swimming pool water through the line 23 arrive.
