Definitions

  • the invention relates to an acetylene gas reactor which is also suitable for mobile use and preferably works with low pressure, in particular for feeding a motor vehicle engine, consisting of a calcium carbide storage container, a reaction vessel with a water supply device and a collecting container for the calcium hydroxide sludge or lime dust which is produced.
  • acetylene gas developers which have hitherto become known are generally expensive because of their complicated structure and are very susceptible to faults, since the carbide granules have hitherto generally been passed through screw conveyors and the like under a sprinkler device. They are also generally only suitable for stationary, but not for mobile use. Especially if you want to use them to power a motor vehicle engine, they cannot work properly because of the vehicle vibrations that inevitably occur in motor vehicles and prevent the proper operation of screw conveyors and the like.
  • a tubular sieve-shaped guide enclosed by the reaction vessel is arranged in a vertical orientation under the carbide container, which is surrounded by an annular jet nozzle arrangement for supplying the water required for the reaction and into a funnel arranged under the guide tubular collection container opens and that the reaction vessel encloses the carbide container, the jet nozzle arrangement, the water storage container and the collection container.
  • the components arranged one above the other in vertical alignment i.e.
  • the calcium carbide storage container located above, the sprinkling chamber underneath and the collecting container, which is arranged under the sprinkling chamber in a coaxial orientation, ensure a constant supply of the carbide granules and also a continuous removal of the hydroxide sludge after appropriate consumption.
  • the reactor can be designed as a closed cylindrical unit, on the housing of which only connections have to be provided for filling in the carbide granules, for removing the generated gas, for filling up the water of reaction and for removing the hydroxide sludge.
  • the jet nozzles are arranged in a ring around the carbide feed path of the reactor in such a way that they support the calcium carbide feed and contribute to self-cleaning of the feed path.
  • the reactor according to the invention is enclosed by a cylindrical housing 1.
  • the housing 1 When the reactor is in operation, the housing 1 is set up in such a way that its cylinder axis is essentially vertical.
  • the upper end face 2 of the housing 1 is recessed in a dome shape and has a filling opening 3 in its center, which can be closed gas-tight with a screw plug 4 and an interposed sealing washer 5.
  • a basket-shaped insert In the upper section of the housing 1 there is a basket-shaped insert which serves to hold the calcium carbide required for the reaction.
  • the sealing plug 4 When the sealing plug 4 is open, the dome-shaped countersunk end face 2 facilitates the filling process.
  • the plug 4 cannot protrude beyond the cylindrical contour of the housing 1.
  • the insert 6 receiving the calcium carbide has a funnel-shaped base 7 which merges into a short pipe socket 8 in the middle part.
  • a cylindrical screen basket 9 Connected to the pipe socket 8 is a cylindrical screen basket 9, which can consist of perforated sheet metal or of wire mesh. At the upper free end, the carbide granulate can enter the screen basket 9 and fill it up to the bottom of the screen basket, which is also designed as a screen.
  • the sieve basket 9 is surrounded by a nozzle arrangement 10 to be described below, with which the water required for the reaction can be sprayed against the walls of the sieve basket and against the calcium carbide contained in the sieve basket.
  • a collecting container 11 in the housing 1 which surrounds the strainer basket 9 in its upper, cylindrical section 12 which is open at the top.
  • a substantially conical section 13 adjoining section 12 merges in the central region into a further cylindrical section, the diameter of which essentially corresponds to the diameter of the strainer basket 9 and serves as a sludge collecting pipe 14 in a manner to be described below.
  • the sludge collecting pipe 14 is sealingly connected to a central opening 15 in the lower end face 16 of the housing 1.
  • the lower end face 16 is also recessed in a dome shape and can be closed in the middle with a screw plug 17 and a sealing washer 18.
  • the walls of the container are impermeable with off taking water outlet openings in the sludge collecting pipe 14 close to the transition to the conical section 13. These openings 19 are preferably relatively narrow slots which retain solid components but can allow the water to pass through.
  • the lower part of the housing 1 between the cylindrical side walls, the lower end face 16 and the sludge collecting pipe 14 below the openings 19 forms the actual water storage space 20.
  • a gas-tight filler neck 21 is used to fill up the water storage space 20, which is preferably slightly above the in the housing 1 normally provided water level flows.
  • Another connection piece 22, which crosses the side wall of the housing 1, serves to feed the aforementioned nozzle arrangement 10.
  • the nozzle arrangement 10 already mentioned consists of an annular tube 23 which surrounds the screen basket 9 concentrically.
  • This ring pipe 23 is connected to a radial pipe 24, which also serves to secure the position of the ring pipe 23, with a connecting piece 25 in the side wall of the housing 1.
  • the ring tube 23 On the inner circumference of the ring tube 23 there are several spray nozzles distributed over the circumference, via which the water required on the ring tube can be fed in the direction of the strainer basket.
  • the spray nozzles 26 are directed so that they can irradiate a large part of the walls of the screen basket 9 and the calcium carbide contained therein. However, at least some of the nozzles 26 are preferably directed such that they support the passage of the calcium carbide particles from the insert 6 to the sludge collecting pipe 14.
  • a water pump 27 is used, which is switched on with pipes 28 and 29 between the connecting pieces 22 and 25.
  • This pump 27 is preferably a pump that is driven electrically from the on-board battery.
  • the gas pressure prevailing in the entire housing 1 can also be used to convey the water from the reservoir 20 to the ring tube 23 or to support the conveyance.
  • a pump 27 If a pump 27 is used, it is controlled by a sensor 30, which detects the gas pressure prevailing in the housing 1 via a connecting piece 31 and only switches on the pump 27 when a preset minimum pressure of, for example, 100 mb is not reached.
  • the sensor 30 thus forms the switch-on device for the pump 27, which is connected to the on-board battery via the sensor 30.
  • the developed acetylene gas is removed from the housing 1 via a gas outlet connection 32, which is connected via a pipeline 33 to a pressure reducing valve 34.
  • the pressure reducing valve is adjustable in order to adjust the working pressure of the gas.
  • a pipeline 35 leads from the pressure reducing valve 34 to the actual gas valve 36, which is connected to the mixer valve 38 via a pipeline 37.
  • the mixer valve 38 receives the air required for combustion from an adjustable air valve 40 via a further pipeline 39.
  • optimally combustible gas can be discharged with the help of the valves 36 and 40, with which the gas intake connection of the motor vehicle is then fed can.
  • the calcium carbide of the insert 6 also fills the sieve basket 9, where the carbide particles can be supported on the sieve bottom.
  • the sludge collecting tube 14 inside the water storage container is empty and sealed at the bottom with the screw plug 17.
  • the sensor 30 If the sensor 30 now detects that there is too little or even no gas pressure inside the housing 1, it actuates the pump 27, so that the water pumped out of the water reservoir 20 via the spray nozzles 26 of the ring tube 23 against the carbide granules in the sieve basket 9 is sprayed. As a result of this spraying, acetylene gas develops, which steadily increases the pressure in the housing until the sensor 30 responds again and switches off the pump 27 when a maximum pressure is reached. The pump 27 is only switched on again when the sensor 30 detects an insufficient gas pressure.
  • these particles disintegrate and can, if smaller than the mesh opening of the sieve basket, fall out downwards.
  • the sludge collecting tube 14 is preferably dimensioned such that it can absorb the carbide residues from a complete filling of the insert 6. If the carbide supply is now used up and the sludge collecting pipe 14 is filled, 4 new calcium carbide granules can be filled in via the stopper and the carbide residues can be reduced Remove the opening of the screw plug 17 at the lower end of the housing 1. If the latter is lined with a cylindrical bag in the manner of vacuum cleaner bags after emptying the sludge collecting tube, the removal of the carbide residues is not only very easy, but also very clean.
