Definitions

  • the invention relates to a device for feeding a liquid odorant into a gas network, comprising a housing which is designed as a pipe section through which gas can flow, an odorant nozzle and an evaporation body, the odorant nozzle and the evaporation body being sealed in the opening through an opening in the wall of the housing the housing are inserted.
  • odorants malodorous substances are usually considered, which give the natural gas a sulfur-like odor.
  • a widely used odorant is, for example, tetrahydrotiophene (THT).
  • THT tetrahydrotiophene
  • low-sulfur and sulfur-free odorants have also been used for a number of years.
  • odorization is carried out by the gas network operator of the gas distribution network in question when the gas is withdrawn from the gas transport network and when the pressure is reduced to the pressure prevailing in the gas network distribution pressure.
  • a liquid odorant is added via an odorization system in a local gas pressure control and measuring system (GDRM system). The addition takes place depending on the size of the 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 fed to an odorant nozzle by means of a pulse-controlled metering pump.
  • This odorant nozzle or also inoculation nozzle is generally designed as a dip tube inserted into the gas line.
  • the odorant is fed intermittently to the immersion tube inserted in the gas line, the immersion tube being flowed around by the natural gas flowing through the gas line.
  • the liquid odorant evaporates and is absorbed by the natural gas.
  • the odorant is not atomized when it is injected into the immersion tube and is fed to the immersion tube discontinuously or intermittently in the direction of the weight force. It cannot be ruled out that the odorant does not evaporate on or in the immersion tube and that the significant quantities of liquid odorant are entrained by the gas flow and distributed in an uncontrolled manner in the gas line. It has already occurred in practice that significant quantities of liquid odorant collect in the gas line below the injection nozzle.
  • the U.S. 5,304,327 discloses a device according to the preamble of claim 1. It describes a device for feeding a liquid odorant into a gas network.
  • the device has a threaded sleeve which can be screwed into a connection piece of a gas-carrying pipe.
  • the device also has a conduit pipe which is held in a sealing manner by the threaded sleeve and extends into the free cross section of the pipe.
  • a perforated pipe having openings is attached to the conduit pipe by means of a metering nozzle, an evaporation body in the form of steel wool being arranged inside the perforated pipe.
  • the invention is therefore based on the object of providing a device for odorizing a gas flow in a gas network with which the aforementioned disadvantages are eliminated.
  • One aspect of the invention relates to a device for feeding a liquid odorant into a gas network according to claim 1, comprising a housing which is designed as a pipe section through which gas can flow, an odorant nozzle, a Evaporation body, wherein the odorant nozzle and the evaporation body are inserted into the housing in a sealed manner through an opening in the wall of the housing in the opening, so that the evaporation body extends at least over a part of the free cross section of the housing in the housing and a valve body, which is of a first open position can be brought into a second closed position, wherein the valve body closes the gas-permeable cross-section of the housing in the second position and releases the gas-permeable cross-section of the housing in the first position and the valve body in the second position with the housing an extraction lock for the Evaporation body and / or the odorant nozzle forms.
  • a device for feeding in a liquid odorant which comprises a housing with an evaporation body extending therein, into which a liquid odorant is introduced via an odorant nozzle so that the evaporation body is wetted and promotes evaporation of the odorant.
  • the housing is also designed as an extraction lock for the evaporation body.
  • the evaporation body can extend essentially over the entire clear width of the free housing cross-section within the housing.
  • the evaporation body can be provided, for example, as an open-pored foam body, preferably as one that has a certain inherent stability.
  • the evaporation body can be designed, for example, as a rigid foam body with a macropore structure through which gas can flow.
  • a macropore structure in the context of the invention is to be understood as an open pore structure with a pore diameter in the order of millimeters, for example the pores of the evaporation body can have a diameter between 1 mm and 10 mm, preferably between 4 mm and 5 mm.
  • the evaporation body is formed from a metal foam, for example from aluminum foam.
  • metal foams based on iron or nickel can be used.
  • such metal foams can be used which have been produced from iron-based and nickel-based powder in the slip reaction foam sintering process.
  • evaporation bodies can also be provided as plastic foam bodies.
  • the evaporation body can be provided in an enclosure through which gas can flow or in a housing through which gas can flow, which can also be designed, for example, in the form of a perforated immersion tube.
  • the evaporation body can be designed as a housing with a fiber filling or a lamellar structure.
  • Metal wool or steel wool, for example, can be provided as the fiber filling.
  • chemically resistant plastic fibers can be arranged in a housing provided with throughflow openings.
  • the special design of the extraction lock according to the invention makes it possible to replace the evaporation body essentially without dismantling and taking the gas line out of operation. A simple exchange of the odorant nozzle with the evaporation body is also of course possible or just the odorant nozzle.
  • An extraction lock in the sense of the present invention is to be understood as a space within the housing which can be hermetically shut off relative to the pipe section through which gas can flow.
  • the extraction lock for the odorant nozzle and / or the evaporation body is formed by only a single valve body, which at the same time blocks the cross section of the gas line. This eliminates the need to shut off the housing of the device for feeding in the liquid odorant on both sides of a connection to the gas line.
  • a bypass line for the device according to the invention.
  • valve body has a lock chamber which cooperates with a valve seat of the housing in such a way that the valve seat seals the lock chamber when the valve body is in the second, closed position.
  • a cavity can be provided in the valve body which is dimensioned such that it can accommodate the evaporation body and preferably also parts of the odorant nozzle.
  • the evaporation body can be arranged, for example, in an immersion sleeve or an immersion tube of the odorant nozzle.
  • the evaporation body and the odorant nozzle can, for example, form an entire unit to be handled in the form of a cartridge.
  • the odorant nozzle can have a pre-expansion valve that is expediently arranged on a part of the odorant nozzle that extends outside the housing.
  • the valve body is designed as a ball valve body which has a through-flow channel.
  • the odorant nozzle and / or the evaporation body can, for example, pass through a passage in a pole of the ball valve body.
  • a ball valve body expediently comprises two diametrically opposite poles which define the axis of symmetry and the axis of rotation of the ball valve body.
  • a switching shaft for actuating the ball valve body can act on one pole, and a passage can be provided on the opposite pole, into which the odorant nozzle and / or the evaporation body are immersed.
  • the ball valve body can expediently be actuated via a ball valve which is fastened to a switching shaft penetrating the housing.
  • valve body is designed as a slide, in particular as a wedge slide, which can be actuated via a spindle drive.
  • the housing has a first, second and third pipe outlet, that the valve body releases the third pipe outlet in the second closed position and that the third pipe outlet is preferably closed with an inspection cover.
  • the inspection cover with the housing limits the removal lock.
  • the inspection cover can be provided with a sight glass, for example, which enables a visual inspection of the extraction lock, the evaporation body or the odorant nozzle.
  • the first, second and third pipe outlet can all have approximately the same cross section, the first and second pipe outlet forming the pipe section of the device through which gas can flow.
  • a relatively large access opening to the extraction lock is provided through the third pipeline outlet. This makes it possible to insert a component, such as the odorant nozzle or the evaporation body, into the device from the side. As a result, a larger cross section is available for introducing components into the device.
  • a pre-expansion of the lock chamber can take place in the manner described above or via a connection which is arranged in the area of the removal lock.
  • FIG. 1 illustrates the basic structure of an arrangement for odorising a gas flow.
  • the reference number 1 denotes a pipe section of a gas line, which is connected downstream of a gas meter 3 in the flow direction of the gas.
  • the arrangement including the device according to the invention is arranged, for example, in a GDRM system of a local gas distribution network.

  • a liquid odorant for example in the form of THT, is introduced into the gas line 2 via a device 4 for feeding in the liquid odorant.
  • the odorant is taken from an odorant container 5 and fed to the device 4 via a metering pump 6.
  • the metering pump 6 is connected to the gas meter 3 via a control device 7.
  • the gas meter 3 supplies information via a volume corrector 8 to a pulse generator, not shown in the figure, which in turn transmits control pulses to the control unit 7.
  • the metering pump 6 receives corresponding control signals via the control unit 7, which are each converted into injection strokes of the metering pump 6, which is designed, for example, as a piston pump.
  • the pulse generator can for example be designed as a goal counter or the like.
  • FIG Figure 2 A first variant of the device 4 according to the invention is shown in FIG Figure 2 shown.
  • the device 4 comprises a housing 9, which is designed as a pipe section through which gas can flow, which has a first and second connection flange 10a, 10b which can be connected to pipe sections of the gas line 2 and whose nominal diameter is matched to the nominal diameter of the gas line 2 in question.
