Large reactor for preparing acetylene and synthesis gas through partial oxidation of hydrocarbon

Abstract

A large reactor for preparing acetylene and synthesis gas through partial oxidation of hydrocarbon comprises a mixing area, a reaction area and a quenching area. In the mixing area, a hydrocyclone and a lateral air intake grid are arranged, either hydrocarbon or oxygen passes through the hydrocarbon and the other passes through the lateral air intake grid, then the two gases are fully and evenly mixed in the mixing area, and the mixing degree of hydrocyclone and oxygen reaches 99.9%. In the reaction area, a nozzle plate and a nozzle arranged on the nozzle plate are arranged, and the gas mixture is sprayed into the reaction area through the nozzle for partial oxidation reaction. In the quenching area, an internal component is arranged to achieve cold-wall operation, a quenching nozzle is arranged on the outer wall of the internal component, the spray range of a quenching medium required by pyrolysis gas quenching is shortened, pyrolysis gas quenching effect is guaranteed, and the production capacity of the reactor reaches thirty thousand tons per year or more.

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...
