Microporous membrane type oxygen distributor for membrane type oxygenation reaction of phosphorus oxychloride

Abstract

The invention provides a microporous membrane type oxygen distributor for membrane type oxygenation reaction of phosphorus oxychloride. The microporous membrane type oxygen distributor comprises gas distribution pipes, round holes, cylinders, springs, a through opening, an arc-shaped plate, transparent glass, an arc-shaped groove and a ribbon, wherein the cylinders are assembled at the left sidesof the inner parts of the gas distribution pipes; the round holes are formed in annular side surfaces of the cylinders; the left ends of the springs are fixedly arranged on the left end surfaces of the inner parts of the cylinders, and the right ends of the springs penetrate through rubber rings and are arranged on the left end surfaces of fixed rings; the arc-shaped plate is assembled in the arc-shaped groove; the transparent glass is arranged on the left end surface of the arc-shaped plate; a connecting rod is provided with a connecting rod body and connecting heads fixedly connected with two ends of the connecting rod body; connecting positions between the connecting heads and the connecting rod body are of hollow tubular structures; the connecting rod body is in interference fit with the connecting heads; two ends of the connecting rod body are respectively pressed in hollow pipes of the two connecting heads. According to the microporous membrane type oxygen distributor disclosed by the invention, an oxygen outlet can be automatically closed, so that an oxygen circulating situation can be conveniently judged, the stability is good, and the reliability is high.

Description

technical field [0001] The invention relates to a microporous membrane type oxygen distributor for phosphorus oxychloride membrane type oxygen flow reaction, which belongs to the field of phosphorus oxychloride production equipment. Background technique [0002] Phosphorus oxychloride, an industrial chemical raw material, is a colorless and transparent fuming liquid. It is a colorless and transparent liquid with a pungent odor. It fumes violently in humid air and is hydrolyzed into phosphoric acid and hydrogen chloride, which further generate HP 2 o 4 Cl 3 . [0003] In the prior art, there are still many deficiencies in the oxygen distributor. The oxygen outlet is generally in an open state, which is easy to enter debris and cause pipeline blockage. Oxygen circulation or not, the interruption of oxygen circulation cannot be detected in time, so a microporous membrane oxygen distributor for phosphorus oxychloride membrane oxygen reaction is urgently needed to solve the a...
