Large reactors for the partial oxidation of hydrocarbons to acetylene and synthesis gas, including mixing, reaction and quenching zones. In the mixing zone, there is a swirler and a side air inlet grid. One of the hydrocarbons and oxygen passes through the swirler, and the other passes through the side air inlet grid. Then the two streams are fully and uniformly mixed in the mixing area, and the hydrocarbon The mixing degree with oxygen reaches 99.9%. In the reaction zone, a burner plate and burners arranged on the burner plate are arranged, and the mixed gas is sprayed into the reaction zone through the burner for partial oxidation reaction. In the quenching area, built-in components are set to realize cold wall operation, and quenching nozzles are set on the outer wall of the built-in components to shorten the spraying range of the quenching medium required for cracking gas quenching, ensure the quenching effect of cracking gas, and realize the production capacity of the reactor. More than 30,000 tons / year.
Description
technical field [0001] The invention relates to an acetylene reactor device, in particular to a large-scale reactor device for producing acetylene by partial oxidation of hydrocarbons, which belongs to the field of chemical industry, especially the field of natural gas chemical industry. Background technique [0002] Acetylene is the simplest alkyne and is an important chemical raw material used to produce a series of chemical products such as acetic acid, vinyl acetate, vinyl acetylene, acrylic acid, butadiene, 1,4-butanediol, etc. Monomers of materials such as synthetic rubber, synthetic fibers, and plastics. As a representative of partial oxidation of hydrocarbons to acetylene, partial oxidation of natural gas to acetylene co-production of synthesis gas can efficiently utilize resources such as natural gas, shale gas and coalbed methane, and is a natural gas chemical technology with good economics. In recent years, with the efficient exploitation of resources such as sha...
