Definitions

  • hypochlorite it is also known to add hypochlorite to the water instead of chlorine, the sodium hypochlorite being produced by electrolysis from common salt.
  • DE-A-1 178 941 also already shows a circuit arrangement for starting up a gas discharge lamp which, from an alternating current source using a supply circuit arrangement dimensioned for the internal voltage and the internal current, in the form of a voltage multiplier circuit composed of rectifier diodes and capacitors and at least one high-voltage supplying, less powerful Ignition circuit, the supply circuit and the ignition circuit being combined to form a voltage multiplier circuit consisting of a plurality of voltage stages connected in series and operated in DC mode using a smoothing choke.
  • This circuit arrangement already enables optimization of the operating costs by keeping the combustion current constant with greater accuracy. This also increases the lifespan of the components.
  • the invention has for its object to develop a device with the features of the preamble of claim 1 such that the investment and operating costs can be further reduced with improved efficiency and the life of the device used is increased. This object is achieved by the characterizing features of claim 1. Advantageous developments of the invention result from the subclaims.
  • the device explained above is characterized according to the invention by a gas discharge lamp in a treatment chamber with an air supply pipe and an air discharge pipe, in a gas-filled UV-permeable pipe and with electrodes which are made of a DC voltage multiplier circuit from one AC network is powered with a switch.
  • a pole-reversal switch is arranged between the DC multiplier circuit and the gas discharge lamp, which is actuated by an excitation coil, and if a delay circuit is arranged in a supply line of the rectifier-multiplier circuit, which switches the DC-multiplier circuit via a controlled normally open contact with a delay compared to the polarity reversal.
  • the proportion of ozone generated in the air passed through the treatment chamber can be controlled in that, according to a further feature of the invention, a controllable compressor is arranged in the air supply line to the treatment chamber.
  • a particularly favorable starting behavior and a long service life of the gas discharge lamp are obtained if, according to a further feature of the invention, a gas discharge lamp is used in the device or circuit arrangement described, in the known cold start sintered electrodes (US Pat. No. 3,325,281) ) are used as electrodes.
  • the UV radiation intensity follows the sine law of the current and is therefore proportional to the arithmetic mean l ar of a current half-wave on average over time.
  • the electrical energy converted into useless heat in the tube is proportional to the effective value leff of the current half-wave.
  • the drawing schematically shows a device or circuit arrangement for generating ozone from oxygen, in particular atmospheric oxygen, by means of UV radiation from a gas discharge lamp.
  • the ozone is generated from the atmospheric oxygen which is in the air flow flowing through a treatment chamber 15 with an air supply pipe 13 and an air discharge pipe 14.
  • the ozone is generated by the action of UV radiation, which is generated in a gas discharge lamp 6 with electrodes 7, 8 and emerges from the UV-permeable glass tube 17, for example made of quartz glass, which forms the gas discharge lamp.
  • the air flow led through the treatment chamber 15 can be increased or accelerated by a compressor 16 arranged in the air supply line 13.
  • the gas discharge lamp 6 is fed via a rectifier-multiplier circuit 5 from an AC network with mains lines 1 and 2.
  • a power switch 3 is attached to one of the power lines.
  • the gas discharge lamp 6 is operated with direct current by the rectifier multiplier circuit 5.
  • the DC voltage multiplier circuit 5 consists of several series-connected voltage doubling stages, known per se.
  • the DC operation results in energy savings of up to 30%. There is also no annoying flickering when the lamp is switched on immediately. As long as the gas discharge lamp 6 has not yet ignited, the rectifier multiplier circuit 5 supplies a very high voltage at zero current, which causes the gas discharge lamp 6 to ignite. After the ignition, the internal resistance of the gas discharge lamp 6 decreases significantly, so that the operating current can increase considerably.
  • a reversing switch 9 can be arranged in the voltage supply of the gas discharge lamp 6. Due to the arrangement of the polarity reversing switch 9, the polarity is switched without load each time the gas discharge lamp 6 is switched on, so that the occurrence of a cataphoresis is prevented.
  • the pole-reversal switch 9 which is designed as a current surge pole-reversal switch, is actuated by a relay coil 4 (via connections shown in broken lines).
  • the relay coil 4 is designed, for example, for 220 volt AC voltage.
  • a delay circuit 10 is provided in a feed line, which switches a normally open contact 12.
  • the circuit 10 can have, for example, a relay coil and a capacitor connected in parallel (not shown), which results in a delayed switch-on of the normally open contact 12 compared to the switch-on by the mains switch 3 and the reverse polarity by the relay 4.
  • the relay in delay circuit 10 pulls within a half period, i.e. within about 10 msec at 50 Hz AC voltage.
  • the rectifier multiplier circuit 5 is connected to the mains voltage later than after 10 msec, for example after 50 msec at the earliest, i.e. 2.5 alternating voltage periods, but expediently not later than 100 msec.
  • a double-pole, electromagnetic impulse changeover switch can serve as the pole-reversal switch 9.
  • the delay circuit 10 can be supplied, for example, via a rectifier arrangement (not shown) which is directly connected to the network 1, 2.
  • the changeover contacts of the changeover device 9 are switched without load by means of the relay 4, so that the rectifier voltage multiplier device 5 is not yet working, because the normally open contact 12 is still open.
  • the polarity reversing device 9 is in a polarity which is reversed compared to the previous operating period.
  • the pole-reversal switch 9 with the instantaneous excited coil 4 will first flip the contact apparatus. Then, with a selectable delay of at least 50 msec, the rectifier multiplier circuit 5 is connected to the mains via the contact 12 closed by the delay circuit 10. Each time the mains switch 3 is closed, the gas discharge lamp 6 is reversed without load before it turns is caused to ignite and burn by the rectifier multiplier circuit 5. This avoids a cataphoresis effect in the gas discharge lamp 6 operated with direct current.
  • the gas discharge occurring between the electrodes 7, 8 causes the generation of UV radiation, the energy of which is sufficient to generate ozone from (air) oxygen.
  • the UV radiation generated can exit or enter through the glass tube 17 into the treatment room 15, where it can convert 0 2 to 0 3 .
