Description

i 147601in 147601

Opfindelsen angår en acetylengas-generator, især til forsyning af en bilmotor med gasblanding, og indeholdende en forrådsbeholder for calciumcarbid, et derunder liggende reaktions-rum med vandtilførsel og en samlebeholder for det dannede 5 calciumhydroxidslam.The invention relates to an acetylene gas generator, in particular for supplying a gas engine automobile engine, and containing a calcium carbide storage tank, an underwater reaction room and a calcium hydroxide sludge collecting tank.

De hidtil kendte acetylengas-generatorer er alle på grund af deres komplicerede opbygning kostbare og meget ømfindtlige, fordi carbidgranulatet hidtil er blevet ført ind under et overrislingsaggregat ved hjælp af transportsnegle eller 10 lignende. Desuden er de i almindelighed kun egnet til stationært brug, men ikke til mobilt brug. Hvis man ville anvende dem til forsyning af en bilmotor med brændstof, ville de ikke kunne arbejde korrekt, fremfor alt fordi der i biler uundgåeligt optræder rystelser, der forhindrer en kor-15 rekt funktion af transportsnekker og lignende.The prior art acetylene gas generators are all expensive and very delicate because of their complicated structure because the carbide granulate has so far been introduced into an irrigation unit by means of transport augers or the like. Furthermore, they are generally only suitable for stationary use, but not for mobile use. If they were to use them to supply a car engine with fuel, they would not be able to work properly, mainly because in cars inevitably there are shakes that prevent a proper functioning of the transport carpenter and the like.

Opfindelsen har til formål at anvise en forbedret acetylengas-generator, der ikke har de før omtalte ulemper, og som arbejder uden komplicerede og upålidelige transportorganer for carbidgranulatet, samt på grund af sin kompakte opbygning 20 også egner sig til efterfølgende indbygning i en bil med Otto-motor.The invention has for its object to provide an improved acetylene gas generator which does not have the aforementioned disadvantages and which works without complicated and unreliable transport means for the carbide granulate, and because of its compact structure 20 is also suitable for subsequent incorporation in a car with Otto -engine.

Dette er ifølge opfindelsen opnået ved, at carbidbeholderen har en mod midten nedadrettet, tragtformet bund, som i midten går over i en ned i reaktionsrummet ragende rørformet, som 25 en si udformet føring, der er omgivet af et ringformet dyseaggregat til tilføring af det til reaktionen nødvendige vand, og at reaktionsrummet har en tragtformet bund, som udmunder i en rørformet samlebeholder for slammet, og at der i den ne-derste del af reaktionsrummet findes et slamsamlebeholderen 30 ringformet omgivende vandforrådsrum, der via en pumpe er forbundet med dyseaggregatet, og at dettes dyser er rettet ind mod aksen af føringen og ned mod samlebeholderen, og at den tragtformede bund førende til slamsamlebeholderen strækker sig i det væsentlige over hele tværsnittet af reaktionsrummet, 35 samt at vandforrådsrummet har en i siden anbragt påfyldnings- 2 147601 studs, carbidbeholderen en foroven anbragt lukbar påfyldningsåbning, bunden af slamsamlebeholderen en udefra tilgængelig lukkeprop, og reaktionsrummet en i siden anbragt studs til udtagning af acetylengas.This is achieved according to the invention in that the carbide container has a center-down, funnel-shaped bottom which in the middle goes into a tubular projecting down into the reaction space, such as a sieve formed enclosed by an annular nozzle assembly for supplying it to the and the reaction compartment has a funnel-shaped bottom which opens into a tubular mud container and that in the lower part of the reaction compartment is a mud container 30 annular surrounding water supply space connected via a pump to the nozzle assembly, and that its nozzles are directed toward the axis of the guide and down toward the collecting vessel, and that the funnel-shaped bottom leading to the sludge collecting vessel extends substantially over the entire cross-section of the reaction chamber, and that the water storage space has a laterally filled filling chamber, the carbide container. a closable filling opening located at the top, the bottom of the sludge container an externally accessible closure plug, and the reaction chamber, a side-mounted studs for withdrawing acetylene gas.

5 På grund af de i lodret retning over hinanden anordnede byggedele, dvs. den foroven liggende calciumcarbidbeholder, det derunder liggende reaktionskammer, og den under reak-tionskammeret og koaksialt med dette anordnede slamsamle-beholder sikres en jævn tilførsel af carbidgranulatet og 10 ligeledes en kontinuerlig bortføring af hydroxidslammet fra reaktionskammeret efter reaktion.5 Due to the vertically arranged building parts, i.e. the upper calcium carbide container, the reaction chamber below, and the below the reaction chamber and coaxially disposed with this sludge container ensure a smooth supply of the carbide granulate and also a continuous removal of the hydroxide sludge from the reaction chamber after reaction.

Hvis man anvender en acetylengas-generator ifølge opfindelsen i køretøjer, understøtter de uundgåelige, men nu fordelagtige rystelser i en bil en regelmæssig transport af cal-15 ciumcarbidet. Den koaksiale anordning af delene fører endvidere til, at generatoren kan udformes som et cylindrisk, lukket aggregat, på hvis hus der kun skal anbringes de nævnte tilslutninger til indfyldning af carbidgranulat, til bortledning af den dannede acetylengas, til påfyldning af 20 vand cg til bortføring af hydroxidslammet.Using an acetylene gas generator according to the invention in vehicles, the inevitable but now advantageous shakes in a car support regular transport of the calcium carbide. The coaxial arrangement of the parts furthermore allows the generator to be designed as a cylindrical, closed assembly, on whose housing only the aforementioned connections for filling carbide granules, for discharging the formed acetylene gas, for filling 20 water and for removal are provided. of the hydroxide sludge.

Ved en foretrukket udførelsesform er vandstråledyserne an-ordnet således ringformet omkring den nævnte rørformede si, at vandstrålerne fremmer carbidtransporten og bidrager til selvrensning af sien.In a preferred embodiment, the water jet nozzles are arranged so annularly around said tubular sieve that the water jets promote carbide transport and contribute to self-cleaning of the screen.

25 Opfindelsen vil blive forklaret nærmere i det følgende under henvisning til tegningen, på hvilken fig. 1 skematisk viser et lodret snit gennem en lavtryks-acetylengasgenerator ifølge opfindelsen og fig. 2 et snit efter linien II-II i fig. 1.The invention will be explained in more detail below with reference to the drawing, in which: FIG. 1 is a schematic vertical section through a low pressure acetylene gas generator according to the invention; and FIG. 2 is a sectional view taken along line II-II of FIG. First

30 Som det fremgår af fig. 1, er generatoren ifølge opfindelsen omgivet af et cylindrisk hus 1. Under generatorens drift er huset 1 således opstillet, at dets akse står i det væsentlige lodret. Den øverste endebund 2 af huset 1 er kuppelformet 3 147601 nedsænket og har ved midten en påfyldningsåbning 3, der kan lukkes gastæt ved hjælp af en skrueprop 4 med en tætningsskive 5. I den øverste del af huset 1 findes en kurvformet indsats 6, der tjener til optagelse af det til reaktionen 5 nødvendige calciumcarbid. Med aftaget skrueprop 4 letter den kuppelformet nedsænkede endebund 2 påfyldningsprocessen.30 As can be seen from FIG. 1, the generator according to the invention is surrounded by a cylindrical housing 1. During the operation of the generator, the housing 1 is arranged so that its axis is substantially vertical. The upper end bottom 2 of the housing 1 is domed 3 and has at its center a filling opening 3 which can be closed gas-tightly by means of a screw plug 4 with a sealing washer 5. In the upper part of the housing 1 there is a curved insert 6 which serves to absorb the calcium carbide needed for the reaction. With the removed screw plug 4, the dome-shaped submerged bottom 2 facilitates the filling process.

Desuden rager proppen 4 ikke op over den cylindriske kontur af huset 1.In addition, the plug 4 does not project over the cylindrical contour of the housing 1.

Den calciumcarbidet optagende indsats 6 har en tragtformet 10 bund 7, der i midten går over i en kort rørstuds 8.The calcium carbide receiving insert 6 has a funnel-shaped bottom 7 which in the middle passes into a short pipe nozzle 8.

På rørstudsen 8 er sat en cylindrisk si 9, der består af perforeret plade eller trådvæv. Carbidgranulatet synker ned i sien 9, der fyldes helt op med carbid helt ned til dens ligeledes som en si udformede bund.On the pipe nozzle 8 is mounted a cylindrical screen 9 consisting of perforated plate or thread tissue. The carbide granulate sinks into screen 9, which is filled up with carbide right down to its likewise shaped sieve.

15 Sien 9 er omgivet af et i det følgende nærmere beskrevet dyseaggregat 10, ved hjælp af hvilket det til reaktionen nødvendige vand kan sprøjtes mod væggene af sien 9 og dermed mod det i sien indeholdte calciumcarbid.The screen 9 is surrounded by a nozzle assembly 10 described below, by means of which the water needed for the reaction can be sprayed against the walls of the screen 9 and thus against the calcium carbide contained in the screen.

Under indsatsen 6 findes der i huset 1 en opsamlingsbeholder 20 11, hvis øverste, opad åbne cylindriske del 12 omgiver si en 9. En til delen 12 sluttet konisk del 13 går ved midten af huset 1 over i en anden cylindrisk del, hvis diameter i det væsentlige svarer til diameteren af sien 9, og som på den i det følgende nærmere beskrevne måde tjener som et slam-25 samlerør 14. Slamsamlerøret 14 er tætnende sluttet til et centralt hul 15 i den nedre endebund 16 af huset 1.Under the insert 6 there is in the housing 1 a collecting container 20 11, the upper, upwardly open cylindrical part 12 surrounding a 9. A tapered part 13 connected to the part 12 passes at the center of the housing 1 into another cylindrical part whose diameter in substantially corresponds to the diameter of the screen 9 and serves in the manner described below as a sludge collector tube 14. The sludge collector tube 14 is sealingly connected to a central hole 15 in the lower end bottom 16 of the housing 1.

Ligesom den øvre endebund 2 er også den nedre endebund 16 kuppelformet indsænket, og det centrale hul 15 kan lukkes ved hjælp af en skrueprop 17 med en tætningsskive 18. Væg-30 gene af opsamlingsbeholderen 11 er ugennemtrængelige med undtagelse af nogle vandudløbshuller 19 i slamsamlerøret 14 nær ved overgangen til den koniske del 13. Disse huller 19 er fortrinsvis udformet som smalle slidser, der tilbagehol- 4 147601 der faste bestanddele, men lader vand strømme igennem.Like the upper end bottom 2, the lower end bottom 16 is also domed and the central hole 15 can be closed by means of a screw plug 17 with a sealing disc 18. The walls of the collecting container 11 are impermeable except for some water outlet holes 19 in the sludge collector tube 14. near the transition to the tapered portion 13. These holes 19 are preferably formed as narrow slits which retain solid constituents but allow water to flow through.

Rummet i den nederste del af huset 1, dvs. mellem dets cylindriske sidevægge, den nedre endebund 16 og slamsamlerø-ret 14 under vandudløbshullerne 19, danner et vandforråds-5 rum 20. Opfyldning af vandforrådsrummet 20 sker gennem en gastæt lukbar indfyldningsstuds 21, der fortrinsvis udmunder i huset 1 lidt over den normale vandstand. En anden studs 22, der også går gennem sidevæggen af huset 1, tjener til forsyning af dyseaggregatet 10 med vand.The space in the lower part of the housing 1, ie. between its cylindrical sidewalls, the lower end bottom 16 and the sludge manifold 14 below the water outlet holes 19, forms a water supply compartment 20. Filling of the water supply compartment 20 takes place through a gas tight closable filling nozzle 21, which preferably opens in the housing 1 slightly above the normal water level. A second stud 22, which also passes through the side wall of the housing 1, serves to supply the nozzle assembly 10 with water.

10 Det omtalte dyseaggregat 10 består af et ringformet rør 23, der koaksialt omgiver den cylindriske si 9. Det ringformede rør 23 er ved hjælp af et radialt rettet rørstykke 24, der også tjener til fiksering af det ringformede rør 23, forbundet med en studs 25 i sidevæggen af huset 1.10 The said nozzle assembly 10 consists of an annular tube 23 coaxially surrounding the cylindrical screen 9. The annular tube 23 is connected to a stud 25 by means of a radially directed tube piece 24, which also serves to fix the annular tube 23. in the side wall of the housing 1.

15 I den indvendige omkredsflade af det ringformede rør 23 findes flere langs omkredsen fordelte sprøjtedyser 26, gennem hvilke vandet kan sprøjtes hen mod sien 9. Dyserne 26 er således rettet, at de kan bestråle en stor del af væggene af sien 9 og dermed det i sien indeholdte calciumcarbid.15 In the inner circumferential surface of the annular tube 23 there are several spray nozzles 26 distributed along the circumference through which the water can be sprayed towards the screen 9. The nozzles 26 are arranged so that they can irradiate a large part of the walls of the screen 9 and thus the see contained calcium carbide.

20 Fortrinsvis er mindst nogle af dyserne 26 således rettet, at de fremmer gennemløbet af calciumcarbidpartiklerne fra indsatsen 6 til slamsamlerøret 14.Preferably, at least some of the nozzles 26 are directed so as to promote the passage of the calcium carbide particles from the insert 6 to the sludge collector tube 14.

Til tilføring af trykvand til dyserne 26 i det ringformede rør 23 tjener en vandpumpe 27, der ved hjælp af rørlednin-25 ger 28 og 29 er indskudt mellem studsene 22 og 25. Pumpen 27 drives fortrinsvis elektrisk fra et batteri.For supplying pressurized water to the nozzles 26 in the annular tube 23, a water pump 27 is provided, which is inserted by means of pipelines 28 and 29 between the studs 22 and 25. The pump 27 is preferably electrically driven from a battery.

Imidlertid kan også det i huset 1 herskende gastryk anvendes til at føre vandet fra vandforrådsrummet 20 til det ringformede rør 23, eller i det mindste at understøtte denne 30 vandtilførsel.However, the gas pressure prevailing in the housing 1 can also be used to conduct the water from the water supply room 20 to the annular pipe 23, or at least to support this water supply.

Hvis der anvendes en pumpe 27, styres denne af en føler 30, der via en studs 31 registrerer det i huset 1 herskende gas- 5 147601 tryk, og som kun indkobler pumpen 27, hvis et forudbestemt minimalt tryk på f.eks. 100 mb underskrides.If a pump 27 is used, it is controlled by a sensor 30, which via a stud 31 senses the gas pressure prevailing in the housing 1 and which only switches on the pump 27 if a predetermined minimum pressure of e.g. 100 mb is dropped.

Føleren 30 danner således en aktiveringsanordning for pumpen 27, der gennem føleren 30 kan forbindes med bilens batteri.The sensor 30 thus forms an actuator for the pump 27 which can be connected through the sensor 30 to the car battery.

5 Bortstrømningen af den udviklede acetylengas fra huset 1 sker gennem en gasudløbsstuds 32, der gennem en rørledning 33 er forbundet med en trykreduktionsventil 34. Reduktionsventilen 34 er regulerbar til indstilling af gastrykket på forbrugssiden. Fra reduktionsventilen 34 fører en rørled-10 ning 35 til en gasventil 36, der gennem en rørledning 37 er forbundet med en blandeventil 38. Blandeventilen 38 modtager gennem en yderligere rørledning 39 den til forbrændingen nødvendige luft fra en indstillelig luftventil 40. Gennem en udløbsstuds 41 på blandeventilen 38 kan der ved hjælp af 15 ventilerne 36 og 40 udtages optimalt brændbar gasblanding, der derpå ledes til bilmotorens indsugningsstuds.5 The effluent of the evolved acetylene gas from the housing 1 is effected through a gas outlet nozzle 32 which is connected through a conduit 33 to a pressure reducing valve 34. The reducing valve 34 is adjustable for adjusting the gas pressure on the consumption side. From the reduction valve 34, a pipeline 35 leads to a gas valve 36 connected through a pipeline 37 to a mixing valve 38. The mixing valve 38 receives through an additional pipeline 39 the combustion air needed from an adjustable air valve 40. Through an outlet nozzle 41 On the mixing valve 38, the 15 valves 36 and 40 can be extracted optimally combustible gas mixture, which is then fed to the intake motor of the car engine.

Gasgeneratoren ifølge opfindelsen arbejder på følgende måde:The gas generator according to the invention works as follows:

Efter fjernelse af skrueproppen 4 i den øvre endebund 2 fyldes indsatsen 6 med calciumcarbidgranulat. For at forhindre 20 støj, kan de enkelte partikler af carbidgranulatet være forsynet med et vandopløseligt og gastæt overtrask. Desuden fyldes der gennem indfyldningsstudsen 21 vand ind i vandforrådsrummet 20, således at der fås en vandstand, der ligger lidt under vandudløbshullerne 19.After removing the screw plug 4 in the upper end bottom 2, the insert 6 is filled with calcium carbide granulate. To prevent noise, the individual particles of the carbide granule may be provided with a water-soluble and gas-tight coating. In addition, water is filled through the filling spout 21 into the water supply room 20, so as to obtain a water level slightly below the water outlet holes 19.

25 På grund af tyngdekraften, og under kørselen endvidere fremmet af de normale køretøjsrystelser, fylder calciumcarbidet i indsatsen 6 sien 9 op, idet carbidpartiklerne kommer til at hvile på siens 9 bund. Når generatoren er renset og fri for slam, er slamsamlerøret 14 i vandforrådsrummet 20 tomt 30 og er i bunden tæt lukket af skrueproppen 17.Due to gravity, and while driving, further promoted by the normal vehicle shaking, the calcium carbide in the insert 6 fills up 9 as the carbide particles will rest on the bottom of the screen 9. When the generator is cleaned and free of sludge, the sludge collector tube 14 in the water supply room 20 is empty 30 and is closed at the bottom tightly by the screw plug 17.

Når føleren 30 registrerer, at der inde i huset 1 hersker et for lille, eller slet intet gastryk, aktiverer føleren 30 6 147601 pumpen 27, således at det fra vandforrådsrummet 20 ansugede vand gennem dyserne 26 i det ringformede rør 23 sprøjtes mod carbidgranulatet i sien 9. Ved denne besprøjtning udvikles acetylengas, der forøger trykket i huset 1, indtil 5 føleren 30 igen reagerer ved opnåelse af et maksimalt tryk og derved standser pumpen 27. En ny igangsætning af pumpen 27 sker først, når føleren 30 igen reagerer på et for lille gastryk i huset 1.When the sensor 30 senses that inside the housing 1 there is too little or no gas pressure, the sensor 30 activates the pump 27, so that water sucked from the water supply room 20 through the nozzles 26 in the annular tube 23 against the carbide granulate in the sea 9. In this spray, acetylene gas which increases the pressure in the housing 1 is developed until the sensor 30 reacts again to achieve a maximum pressure, thereby stopping the pump 27. A new start of the pump 27 occurs only when the sensor 30 reacts again to a small gas pressure in the housing 1.

Ved besprøjtningen af calciumcarbidpartiklerne i sien 9 fal-10 der disse partikler sammen og kan derfor falde ud forneden, hvis de er mindre end maskevidden i sien 9.When the calcium carbide particles in the spray 9 are sprayed, these particles collapse and can therefore fall below if they are less than the mesh size of the screen 9.

Nedfaldet af carbidpartiklerne fremmes af vandstrømmen fra dyserne 26. På grund af den koniske del 13 samler det gennemløbende vand og kalkslam samt carbidresterne sig i den 15 nederste centrale del af huset 1, hvor dette materiale optages af slamsamlerøret 14. Det i overskud til dyseaggregatet 10 førte vand, der ligeledes træder koaksialt ind i slamsamlerøret 14, kan fra dettes øverste del bortføres gennem vandudløbshullerne 19 og derved igen nå vandforrådsrummet 20.The decay of the carbide particles is promoted by the flow of water from the nozzles 26. Due to the conical part 13, the running water and lime sludge as well as the carbide residues accumulate in the lower central part of the housing 1, where this material is taken up by the sludge collector pipe 14. It in excess of the nozzle assembly 10 Conducted water which also coaxially enters the sludge manifold 14 may be removed from its upper part through the water outlet holes 19, thereby again reaching the water supply space 20.

20 Slamsamlerøret 14 er fortrinsvis således dimensioneret, at det kan optage carbidresterne efter en fuldstændig fyldning af indsatsen 6. Når carbidforrådet er forbrugt, og slamsamlerøret 14 er fyldt op, kan der tilføres nyt calciumcarbid-granulat gennem påfyldningsåbningen 3, medens carbidrester-25 ne efter fjernelse af skrueproppen 17 kan bortføres fra den nederste del af huset 1. Hvis man efter tømning af slamsamlerøret 14 forer dette med et cylindrisk hylster svarende til en støvsugerpose, kan fjernelsen af carbidresterne ske ikke blot meget nemt, men også på en renlig måde.The sludge collector tube 14 is preferably dimensioned so that it can absorb the carbide residues after a complete filling of the insert 6. When the carbide stock is consumed and the sludge collector tube 14 is filled, new calcium carbide granules can be fed through the filling opening 3 while the carbide residues 25 removal of the screw plug 17 can be removed from the lower part of the housing 1. If, after emptying the sludge manifold 14, it is fed with a cylindrical sleeve similar to a vacuum cleaner bag, the removal of the carbide residues can be done not only very easily but also in a clean manner.

30 Af den foregående beskrivelse fremgår, at der ved hjælp af opfindelsen er opnået en kompakt og glatvægget generator, der på meget enkel måde kan indbygges i biler, også i allerede eksisterende sædvanlige biler. På grund af den gennemført koaksiale udformning af generatoren kan de nødvendigeIt is apparent from the foregoing description that, by means of the invention, a compact and smooth-walled generator, which can be incorporated in cars in a very simple manner, is also obtained in pre-existing conventional cars. Because of the coaxial design of the generator, they may be necessary
