Description

Herstellung von Acetylengas von erhöhtem Druck Bei dem unter dem Namen autogene Schweißung allgemein bekannten Gasschmelzschweißverfahren für Eisen und andere Metalle mittels einer durch die Verbrennung eines Acetylensauerstofgasgemisches erzeugten Stichflamme ergeben sich bekanntlich bei einer Erhöhung des Gasdrucks des dem Schweißbrenner zugeführten Acetylens auf etwa 0,5 atü und mehr gewisse Vorteile, insbesondere hinsichtlich der Verminderung des Sauerstoffverbrauchs und einer guten Regelung der Schweißflamme.Production of acetylene gas at increased pressure In the gas fusion welding process for iron and other metals, generally known under the name of autogenous welding, by means of a jet flame generated by the combustion of an acetylene-oxygen gas mixture, it is known that when the gas pressure of the acetylene supplied to the welding torch is increased to about 0.5 atmospheres more certain advantages, in particular with regard to the reduction in oxygen consumption and good control of the welding flame.

Acetylengas von 0,5 atü läßt sich aber wirtschaftlich nicht wegen der hohen Löslichkeit von Acetylen im Wasser durch Hydrolyse von Calciumcarbid unmittelbar herstellen, sondern kann praktisch nur durch Komprimieren des den üblichen Acetylenentwicklern unter annäherndem -,'itmosph2irendruclz entweichenden Gases erhalten werden, tvozu bisher ausschließlich Kolben- oder Kreiselkompressoren benutzt werden. Da indessen derartige Apparaturen in Anschaffung und Betrieb verhältnismäßig kostspielig und nicht ungefährlich sind, und da ferner auch die Vorrathaltung und der Transport von komprimiertem Acetylengas nicht mit einfachen, wohlfeilen Mitteln möglich ist, so konnte das Hochdruckgasschmelzschweißverfahren bisher in die Technik nicht in dem wünschenswerten Maße Eingang finden.Acetylene gas of 0.5 atmospheres cannot be produced economically because of the high solubility of acetylene in water by hydrolysis of calcium carbide, but can practically only be obtained by compressing the gas that escapes from the usual acetylene generators under almost atmospheric pressure, mostly exclusively so far Piston or centrifugal compressors can be used. However, since such equipment is relatively expensive to purchase and operate and not without risk, and since the storage and transport of compressed acetylene gas is not possible with simple, inexpensive means, the high-pressure gas fusion welding process has so far not been able to enter technology to the extent desired Find.

Gemäß der vorliegenden Erfindung werden nun diese Nachteile der bisher bekannten Verfahren zum Verdichten von den üblichen Niederdruckacetylenentwicklern erzeugtem Acetylengas auf einen für die Zwecke der Hochdruckgasschmelzschw eißung erforderlichen Gasdruck dadurch beseitigt, daß das unter Atmosphärendruck stehende Acetylengas in einem Gasstrahlgebläse verdichtet wird, dem als Treibmittel hochkomprimiertes, nach dem Dissousgasverfahren aufgespeichertes Acetylen zugeführt wird. Hierbei wird zur Verdichtung des niedrig gespannnten Gases die beim Entspannen des hochkomprimierten Acetylengases frei wendende Energie benutzt.According to the present invention, these disadvantages now become the heretofore known methods of densification of the usual low pressure acetylene developers generated acetylene gas to a for the purpose of high pressure gas melt welding required gas pressure eliminated by the fact that the standing under atmospheric pressure Acetylene gas is compressed in a gas jet blower, the propellant is highly compressed, Acetylene that has been stored in the dissolution gas process is supplied. Here is to compress the low-tensioned gas that when releasing the highly compressed gas Acetylene gas is used to release energy.

Das der Treibdüse des Gasgebläses zugeführte hochgespannte Acetylen entströmt derselben mit hoher Geschwindigkeit, reißt dabei das aus einem üblichen Gasentwickler oder Gasometer zugeführte, niedrig gespannte Acetylengas mit sich in den die Treibdüse umgebenden Raum des Gebläses hinein und mischt sich mit ihm unter gleichzeitigem Ausgleich der inneren Gasdrücke. Am anderen Ende des Gebläseraumes gegenüber der Treibdüse ist eine Fangdüse angeordnet, in welcher die Geschwindigkeit des Gasstromes verlangsamt wird, wobei entsprechend der frei werdenden kinetischen Energie eine Verdichtung des Gases erfolgt. Von der Fangdüse gelangt das komprimierte Gas dann entweder unmittelbar in den Schweißbrenner oder zu einem Zwischenbehälter.The high-tension acetylene fed to the propellant nozzle of the gas blower if it flows out of it at high speed, it rips that out of a common one Low tension acetylene gas supplied to the gas generator or gasometer into the space of the fan surrounding the propellant nozzle and mixes with it while at the same time balancing the internal gas pressures. At the other end of the blower room opposite the motive nozzle is a collecting nozzle, in which the speed the gas flow is slowed down, according to the kinetic Energy a compression of the gas takes place. The compressed air arrives from the collecting nozzle Gas then either directly into the welding torch or to an intermediate container.

Da bei den in Frage kommenden Gasdrücken die für die Verdichtung des niedrig gespannten Acetylengases nach dem erfindungsgemäßen Verfahren erforderliche Menge von nach dem Dissousgasverfahren hochkomprimierten Acetylengas verhältnismäßig gering ist, und im übrigen für die Durchführung des neuen Verfahrens nur eine sehr einfache, i wenig Raum beanspruchende und wohlfeile Vorrichtung erforderlich ist, so ist das erfindungsgemäße Verdichtungsverfahren gegenüber den bisher bekannten Acetylengaskompressionsverfahren sehr wirtschaftlich und ermöglicht in fortschrittlicher Weise die Anwendung der Hochdruckgasschmelzschweißung in allen praktisch vorkommenden Fällen unter Verwendung der bereits im Betrieb vorhandenen N'iederdruckentwickler.Since the gas pressures in question for the compression of the low tension acetylene gas required by the method according to the invention lot of acetylene gas, highly compressed according to the dissous gas process is relatively low, and otherwise for the implementation of the new procedure only a very simple, space-consuming and inexpensive device required is, the compression method according to the invention is compared to the previously known Acetylene gas compression process very economical and allows in more advanced Way the application of high pressure gas fusion welding in all practically occurring Cases using the low-pressure developers already available in the company.
