Definitions

  • the invention relates to an apparatus and a method for producing gas mixtures with parts of vaporous, volatile components.
  • the invention has for its object a device and a method for quantitative, easily and exactly reproducible dosing of liquid components to provide in a container with a gas or a gas stream.
  • an applied voltage pulse taking advantage of a certain amount of a liquid usually the piezoelectric effect, a magnetic effect or resistive Heating sprayed through a nozzle.
  • the process is from inkjet printers known from here.
  • Liquid is dosed, for example through a nozzle of a piezoelectric dispenser or through a nozzle of a Dispensers with a micro valve (e.g. micro solenoid valve).
  • Liquid dispenser that is in a device according to the invention can be installed, for. B. in "Nachzin aus der Chemie, December 2000, Wiley-VCH, pp. 1566-1567, describes, what is hereby referred to.
  • several liquid dispensers which are advantageously connected to a control unit can be very complex precision gas mixtures can be produced.
  • the ink jet process is used according to the invention for the production of gas mixtures from one or more gases and the vapor of at least one liquid.
  • the liquids are preferably volatile.
  • a liquid is dosed very precisely into a gas (pure gas or gas mixture).
  • volatile components which are liquid at room temperature and normal pressure, such as liquid hydrocarbons (for example C 5 hydrocarbons and higher), aromatics, alcohols, ethers, ketones, etc. are used.
  • gas mixtures can be generated in a simple manner by varying the frequency or quantity of a liquid component, in particular a volatile component.
  • a gas mixture with vaporous portions of a volatile component is produced by metering the component into a gas stream (pure gas or gas mixture) by means of "ink-jet", the gas flow rate being used to set the desired concentration of the volatile component in the gas in is usually varied or adjusted.
  • the method is particularly suitable for the production of gas mixtures Calibration of measuring devices and for the production of test gas mixtures. Further is the process for perfuming or aromatizing gases such as oxygen Gas, oxygen or breathing gases are used.
  • perfuming or Flavorings are e.g. B. or volatile liquid fragrances or flavors used (e.g. as a fragrance concentrate).
  • Fragrances are, for example, essential oils, which generally contain terpenes.
  • the fragrances serve e.g. for generation a fragrant oxygen-containing gas.
  • the fragrances can save one pleasant smell in the application concentration also a physiological or have other beneficial effects.
  • the device and the method are particularly suitable for the production of small amounts of gas mixture, e.g. B. to produce a precision gas mixture directly on site for direct consumption in a consumer (e.g. at the Calibration in a measuring device or analysis device).
  • Fig. 1 shows a diagram of an apparatus for producing a gas mixture.
  • a compressed gas source 1 e.g. B. a compressed gas line or a compressed gas bottle with a gas
  • gas usually becomes a pressure reducer 3 (optional) led where the pressure of the gas is reduced to a low pressure (working pressure) becomes.
  • a gas line 4 leads from the gas source 1 to a consumer 9 (e.g. measuring device, gas storage or filling device).
  • the Liquid dosing unit with liquid storage chamber 5 e.g. reservoir for VOC
  • liquid path 6 and liquid metering nozzle 7 are arranged on the gas line 4 .
  • the fluid path 6 can be omitted, for example in the case of a liquid tank 5 with an integrated one Nozzle 7. Liquid is injected into the gas line 4 using the liquid metering unit dispensed through the nozzle 7.
  • the liquid metering unit is connected to a control unit 10, which is the liquid metering controls, e.g. B. via voltage pulses.
  • the liquid is dosed in the Usually in a gas stream.
  • the gas flow with the admixed, evaporating Liquid is passed to a consumer 9.
  • In the gas line 4 can Mixing section or mixing device between the mouth of the nozzle 7 and the consumer 9 are arranged.
  • the gas mixture produced is used usually in pressurized gas containers (e.g. pressurized gas cylinders, pressurized cans or compressed gas cartridges).
  • pressurized gas containers e.g. pressurized gas cylinders, pressurized cans or compressed gas cartridges
  • the gas mixture compressed and filled into one or more pressurized gas containers. 1 are this or these pressure gas tank referred to as consumer 9.
  • the gas mixture is in the gas line 4 z. B. arranged a compressor.
