Description
Известны способы получени защитных взрывобезопасных атмосфер путем сжигани природного газа с последующей обработкой продуктов его сгорани .Methods are known for producing protective, explosion-proof atmospheres by burning natural gas, followed by processing the products of its combustion.
Отличительна особенность описываемого способа получени нейтральной защитной атмосферы дл термической обработки металлов состоит в том, что в освобожденные от двуокиси углерода и избытка влаги продукты сгорани природного газа добавл ют необходимое количество природного газа и смесь подвергают конверсии на никелевом катализаторе при температуре 1000°.A distinctive feature of the described method of obtaining a neutral protective atmosphere for heat treatment of metals is that the required amount of natural gas is added to the products of natural gas released from carbon dioxide and excess moisture and the mixture is subjected to conversion on a nickel catalyst at a temperature of 1000 °.
Такой способ получени взрывобезопасной нейтральной защитной атмосферы обеспечивает регулирование углеродного потенциала атмосферы по ее влажности.This method of obtaining an explosion-proof neutral protective atmosphere ensures the regulation of the atmospheric carbon potential according to its humidity.
Природный газ и воздух в соотнощении, близком к теоретическому дл лолного сжигани , проход через расходомеры и смесители, нагнетаетс в камеру сгорани . Продукты сгорани состо т из примерно: 87%Nj 11%СО2, 22,5%Н2О. Необходимое количество продуктов сгорани дл дальнейщей переработки охлаждаетс в холодильнике до те.мпературы примерно 20°. При этом избыток влаги конденсируетс и отводитс в канализацию.Natural gas and air, in a ratio that is close to the theoretical value for complete combustion, is passed through flow meters and mixers into the combustion chamber. The products of combustion consist of approximately: 87% Nj 11% CO2, 22.5% H2O. The required amount of combustion products for further processing is cooled in a refrigerator to a temperature of about 20 °. In this case, the excess moisture condenses and is discharged into the sewer system.
Осушенные продукты сгорани , содержащие до 2,0% влаги, постуnafOT в абсорбер дл поглощени COj.Drained combustion products containing up to 2.0% moisture, transfer to the absorber to absorb COj.
Осущенные и очищенные от СОз продукты сгорани смешиваютс в определенной пропорции с «сырым природным газом и нагнетаютс в реакциопную камеру, наполненную никелевым катализатором и обогреваемую теплом, выдел ющимс при сжигании газовоздущной смеси.Drained and decontaminated products of combustion are mixed in a certain proportion with raw natural gas and injected into a reaction chamber filled with a nickel catalyst and heated by heat released during the combustion of the gas-air mixture.
При температуре 1000° происходит процесс взаимодействи паров воды с природным газом.At a temperature of 1000 ° C, water vapor interacts with natural gas.
№ 148079-2Полученна защитна атмосфера после охлаждени направл етс к нагревательным печам и имеет следующий приблизительный состав: У,0-т-2,5% окись углерода, 5,0-г5,5% водорода, 92,0-г93,0% азота.No. 148079-2 The obtained protective atmosphere after cooling is directed to the heating furnaces and has the following approximate composition: Y, 0-t-2.5% carbon monoxide, 5.0-g5.5% hydrogen, 92.0-g93.0% nitrogen.
Описываемый способ получени взрывобезопасной, нейтральной атмосферы из природного газа с регулированием ее состава по точке росы, т. е. по влажности, может быть целесообразен в крупных термических печах, потребл ющих больщие объемы защитной атмосферы.The described method for producing an explosion-proof, neutral atmosphere from natural gas with its composition controlled by the dew point, i.e., by humidity, may be expedient in large heat-treating furnaces that consume large amounts of protective atmosphere.
Предмет изобретени Subject invention
Способ получени взрывобезопасной нейтральной защитной атмосферы дл термической обработки металлов из природного газа, отличающийс тем, что, с целью регулировани состава указанной атмосферы по ее влажности, в освобожденные от двуокиси углерода и избытка влаги продукты сгорани природного газа добавл ют необходимое количество природного газа и смесь подвергают конверсии на никелевом катализаторе при температуре 1000°.A method of producing an explosion-proof neutral protective atmosphere for the heat treatment of metals from natural gas, characterized in that, in order to control the composition of said atmosphere by its humidity, natural gas combustion products freed from carbon dioxide and excess moisture add the necessary amount of natural gas and the mixture is subjected conversion on a nickel catalyst at a temperature of 1000 °.
