Description
Изобретение относится к способу использования порохового синтез-газа в качестве газа-заменителя ацетилена в процессе кислородной резки металлов.The invention relates to a method for using powder synthesis gas as a replacement gas for acetylene in the process of oxygen cutting of metals.
Пороховой синтез-газ, полученный в ходе газификации утилизируемых нитроцеллюлозных порохов в замкнутом объеме, содержит в своем составе до 80% горючих компонентов СО и Н2. Экспериментально установлено, что пороховой синтез-газ является горючим. Температура горения в среде кислорода при турбулентном потоке горючего и окислителя достигает 2900 К. Теплота горения порохового синтез-газа - 10 МДж/м3.Powdered synthesis gas obtained in the course of gasification of utilized nitrocellulose powders in a closed volume contains up to 80% of the combustible components CO and H 2 . It has been experimentally established that powder synthesis gas is combustible. The temperature of combustion in an oxygen environment with a turbulent flow of fuel and oxidizer reaches 2900 K. The heat of combustion of the powder synthesis gas is 10 MJ / m 3 .
Предлагается использовать пороховой синтез-газ в процессах кислородной резки с помощью экспериментальной установки (см. чертеж), состоящей из газогенератора для получения порохового синтез-газа из нитроцеллюлозных порохов (баллона из углеродистой стали, заправленного пороховым синтез-газом) 1; кислородного баллона 2; редукторов для синтез-газа и кислорода 3; газопроводов 4 и газового резака 5.It is proposed to use powder synthesis gas in oxygen cutting processes using an experimental setup (see drawing), consisting of a gas generator for producing powder synthesis gas from nitrocellulose powders (a carbon steel cylinder filled with powder synthesis gas) 1; oxygen cylinder 2; reducers for synthesis gas and oxygen 3; gas pipelines 4 and gas torch 5.
По сравнению с использованием ацетилена в процессах кислородной резки предлагаемый способ имеет следующие преимущества:Compared with the use of acetylene in oxygen cutting processes, the proposed method has the following advantages:
1) автономность применения:1) autonomy of application:
2) возможность применения в широком диапазоне эксплутационных температур от -50°С до +50°С;2) the possibility of application in a wide range of operating temperatures from -50 ° C to + 50 ° C;
3) использование порохового синтез-газа из утилизируемых порохов в 5...6 раз экономичнее, чем ацетилена, полученного из карбида кальция.3) the use of powder synthesis gas from utilized gunpowder is 5 ... 6 times more economical than acetylene obtained from calcium carbide.
После получения порохового синтез-газа из нитроцеллюлозных порохов непосредственно из газогенератора или из баллона, предварительно заправленного пороховым синтез-газом, газ через редуктор поступает в газопровод и далее в резак.After receiving the powder synthesis gas from nitrocellulose powders directly from the gas generator or from a cylinder pre-charged with powder synthesis gas, the gas through the gearbox enters the gas pipeline and then to the cutter.
Кислород из газового баллона через редуктор по газопроводу поступает в резак и, смешиваясь с синтез-газом, образует горючую смесь.Oxygen from a gas cylinder through a reducer through a gas pipeline enters the cutter and, mixed with synthesis gas, forms a combustible mixture.
Открывают вентили резака, производится воспламенение газовой смеси. Регулируя расход газов кранами резака, выбирают оптимальный режим резки.The torch valves are opened, the gas mixture is ignited. By adjusting the gas flow by the torch taps, choose the optimal cutting mode.
Температура горения порохового синтез-газа в среде кислорода при турбулентном потоке горючего и окислителя достигает 2900 К.The combustion temperature of the powder synthesis gas in an oxygen environment with a turbulent flow of fuel and oxidizer reaches 2900 K.
