  • the invention relates to a device for odorizing a gas stream in a gas line comprising an injection device for injecting a liquid
  • Odorizer in the flowing gas stream through the gas line and a method for odorizing a gas stream in a gas line.
  • the treated natural gas does not have a sufficient warning smell, it must be odorized according to legal regulations (cf for Germany, for example, the DVGW worksheet G 280). For this reason, it is known and customary to add odorant to the natural gas. As odorants are usually substances with sufficient warning smell into consideration, which give the natural gas a sulfur-like odor. A common odorant, for example, is
  • TTT Tetrahydrothiophene
  • a liquid odorant is typically added via an odorizer in a local gas pressure regulating and measuring system (GDRM system).
  • GDRM system local gas pressure regulating and measuring system
  • the addition takes place in dependence on the size of a normalized gas volume flow calculated from the data of the gas meter as well as the gas temperature and the gas pressure.
  • a corresponding amount of odorant is supplied by means of a pulse-controlled metering pump to a seed nozzle, which is designed as an inserted into the conduit dip tube with an evaporation body to which the vaccine nozzle supplied odorant is applied in liquid form.
  • the addition of the odorant is proportional to the amount of gas flowing through.
  • the odorant THT is supplied to the gas stream in Germany, for example, with a value of at least 10 mg / m 3 of gas volume. For other odorants other, sometimes lower limits apply. It is important to ensure that a predetermined limit, for example, of 10 mg / m 3 in THT, is not exceeded during the entire distribution of the gas.
  • Odorant is typically supplied intermittently with the dip tube inserted into the gas line, wherein the dip tube is flowed around by the natural gas flowing through the gas line.
  • the liquid odorant evaporates from the evaporation body and is absorbed by the natural gas.
  • Weight force direction is supplied to the dip tube, it is not excluded that the supplied odorant does not evaporate completely on or in the dip tube and that significant amounts of liquid odorant be entrained by the gas flow and distributed uncontrollably in the gas line. So it has already occurred in practice that accumulate significant amounts of liquid odorant below the Impfdüse in the gas line.
  • EP 2 933 015 A1 discloses a device for odorizing a gas stream in a gas network, in which the odorant injected into the gas line is arranged and arranged in a specific manner
  • Evaporative body is applied to achieve a continuous evaporation of the odorant, even if the odorant in liquid form

  • a two-fluid nozzle has the advantage over a single-fluid nozzle that it can reliably atomize much smaller amounts of odorant and is therefore suitable for odorizing smaller gas volume flows. This is made possible by the fact that in the two-substance nozzle, in addition to the odorant to be atomized, another fluid, in particular a gas, is passed through the two-substance nozzle, through which the energy required for atomization is provided. Single-fluid nozzles no longer work properly at comparable low volume flows of odorant and therefore do not optimally atomize the odorant.
  • Two-fluid nozzle also be provided an evaporation body to which the odorant is applied with the two-fluid nozzle.
  • the odorant is applied by means of a two-fluid nozzle on the evaporation body, a better distribution of the odorant on the evaporation body can be achieved by the atomization of the odorant through the two-fluid nozzle.
