Problems solved by technology

[0005] Aiming at the deficiencies in the existing process and device for producing acetylene by plasma pyrolysis of coal, the present invention proposes a process and device for producing acetylene by plasma pyrolysis of coal and natural gas to solve the existing process and device for producing acetylene by plasma pyrolysis of coal There is a problem that the plasma generator is single, and the load is limited during industrial production; argon is used as a gas protective layer, and its function is single, so it cannot be used as an auxiliary gas for the reaction of coal in the plasma reactor; the self-generated heat energy has not been fully utilized.

Embodiment 1

[0022] The present invention improves it on the basis of existing technology, as attached figure 1 As shown, in the plasma generator (6), at first by the mixed gas inlet of argon and hydrogen, i.e. the working gas inlet (2) into the working gas, then the plasma generator inlet (18) is applied with 0 ~ 400 volts power supply (1), and spray it into the plasma reactor (7) at a speed of 50-80m / s to generate a plasma arc (25), forming a thermal plasma field (28) at 3000°C-8000°C; followed by the natural gas pipe ( After the natural gas in 16) and the pulverized coal gas flow in the pulverized coal flow pipe (15) are preheated through the preheating heat exchanger (14), the 20~ The coal powder of 100 μm is sprayed into the thermal plasma field (28) in the plasma reactor (7) with the speed of 4~6m / s and the amount of coal of 50~90g / min to react, and the acetylene mixed gas generated is in the quencher ( In 9), it is rapidly cooled to 300°C-600°C by the water jet (27) of the quencher...

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...
