Apparatus and process for producing acetylene by plasma pyrolysis of coal and natural gas

Abstract

Production of ethyne by coal and natural gas plasma pyrolyzation and its apparatus are disclosed. It is produced by spraying plasma, buggy steam current and natural gas protective gas in plasma reactor, reacting and generating mixed ethyne gas, cooling, separating, storing ethyne, passing gas into plasma generator and reutilizing, sprayed natural gas forming gas protective layer on plasma reactor wall to prevent carbon fragment from coking, and pyrolytic reacting to obtain mixed ethyne gas. It achieves high converting efficient and reacting efficient.

Description

technical field

[0001] The invention relates to a process and equipment for industrially preparing acetylene, in particular to a process and device for producing acetylene by pyrolyzing coal and natural gas plasma. Background technique

[0002] Acetylene is an important basic chemical raw material. The traditional method of hydrolyzing calcium carbide to prepare acetylene has a long process flow and poor equipment, especially large energy consumption and serious environmental pollution. Many people are currently researching and improving the process and equipment of acetylene. The inventor applied for an invention patent in March this year, "Process and Equipment for Producing Acetylene by Coal Plasma Pyrolysis", which is a relatively advanced high-tech for producing acetylene. The process is to generate plasma in a plasma generator and produce it by The working gas is sprayed into the plasma reactor to form a plasma atmosphere, and at the same time, coal powder is sprayed...
