Abstract

The invention relates to a static mixer for ethylene and oxygen, which mainly solves the problem of unsatisfactory mixing effect of olefin and oxygen in the prior art. The present invention adopts a kind of static mixer of ethylene and oxygen, which comprises ethylene main pipeline, the end of ethylene main pipeline communicates with mixing chamber, a number of oxygen spiral distribution pipes are arranged in the mixing chamber, and oxygen pipeline enters the center of ethylene main pipeline from the side and enters the oxygen distribution chamber. Oxygen enters the spiral distribution pipe through the distributor. The plane of the spiral distribution pipe is perpendicular to the flow direction of ethylene. Several oxygen nozzles are evenly distributed on each spiral distribution pipe. problem, it can be used in the mixture of ethylene and oxygen.

Description

technical field [0001] The present invention relates to a static mixer for ethylene and oxygen. Background technique [0002] There are two industrial production methods of ethylene oxide / ethylene glycol (EO / EG), namely chlorohydrin method and ethylene direct oxidation method. Ethylene direct oxidation is further divided into air oxidation and oxygen oxidation. Compared with the air oxidation method, the oxygen oxidation method has a shorter process flow, less equipment, and less investment in plant construction; the selectivity of the catalyst in the oxidation reaction is high, and the reaction temperature is lower than that of the air method, which can prolong the life of the catalyst and maintain the stable operation of production more favorable. Usually the production cost of oxygen oxidation method is about 10% lower than that of air oxidation method. Due to the obvious advantages of the oxygen oxidation method over the air oxidation method, the oxygen oxidation meth...
