Problems solved by technology

When the acetylene output per unit time is increased to 15,000 tons, due to the enlargement of the flow cross-sectional area, the structure of the mixer device can only make the mixing degree of natural gas and oxygen in the acetylene furnace reactor only reach 98.0%, so Can not meet the requirements of safe and stable operation of acetylene furnace

Abstract

The invention discloses a mixer device of acetylene furnace, which comprises the following parts: oxygen spraying pipe (6) in connection with oxygen inlet (1), vortex tool (4) located by vortex locating piece (5) in the oxygen spraying pipe (6), oxygen vortex piece (9) fixed on the lower circumference of vortex tool (4) evenly, natural gas sprayer (8) in connection with the upper end of composite gas injector (3), wherein the through-hole on the circumference of oxygen spraying pipe (6) interconnects the through-hole on the circumference of vortex tool (4) through interconnecting pipe (11); the natural gas vortex piece (10) is set on the inner circumferential side of upper end of natural gas injector (8) with the opposite direction corresponding to the oxygen vortex piece (9). The gaseous hydrocarbon reactant is preheated with large amount of oxygen in the three-inlet mixer, which is mixed completely to guarantee the effect and manufacturing safety.

Description

technical field [0001] The invention relates to a process device for an acetylene furnace, in particular to a mixer device for an acetylene furnace for producing acetylene and synthesis gas by adopting a natural gas partial oxidation method. Background technique [0002] The raw natural gas and oxygen are heated to 500-650°C respectively in their respective preheating furnaces, enter the acetylene furnace mixer and mix thoroughly, and then enter the acetylene furnace reactor for partial oxidation reaction, in which about 60% of the raw natural gas and oxygen are flamed Combustion, release heat and produce CO, CO 2 、H 2 And water, the generated heat supplies about 30% of the natural gas to undergo a cracking reaction and generate acetylene, and about 5% of the natural gas does not participate in the reaction and exists in the cracked gas in the form of residual methane. At present, the core equipment for acetylene cracking in China, the acetylene furnace, is a multi-tube ve...
