Oxidizing tower in hydrogen peroxide production

Abstract

The invention discloses an oxidizing tower in hydrogen peroxide production, which comprises a tower body and is characterized in that 2 to 5 filler parts are arranged in the tower body. Each filler part comprises a filler press ring arranged on the upper side and a filler support block arranged on the lower side, the filler support blocks are welded to the tower body, a plurality of layers of tongue-shaped fillers are arranged between the filler press rings and the filler support blocks, two adjacent layers of tongue-shaped fillers adopt 90-degree angles for intersection installation, a filler support grating is arranged between the tongue-shaped fillers and the filler support blocks, a filler support beams are arranged at the bottoms of the filler support blocks, a manhole is arranged onthe tower body on one side of the top of the filler parts, and a distributor is arranged at the bottom of the tower body. The oxidizing tower has the advantages of integrally adopting the honeycomb type, enabling two-phase flowing to be more reasonable, reducing stopping time of two-phase easily-gathering objects on the surface of the fillers, strengthening two-phase disturbance degree, enabling two-phase mixing to be more even and improving mass transfer efficiency.

Description

technical field [0001] The invention relates to an oxidation tower in hydrogen peroxide production. Background technique [0002] The main problems of the traditional oxidation tower are as follows: the flow distribution of the two phases is unreasonable; the residence time of the two-phase easy polymers on the surface of the filler is too long, causing polymerization and coking; The mass transfer efficiency is improved; the utilization rate of the packing surface is low, and the mass transfer efficiency is low; the distance between the grid blocks is small, which reduces the flux of the two phases; the grid blocks are not in close contact with the inner wall of the tower, which increases the wall flow and Adverse effects such as axial back mixing reduce the mass transfer efficiency. Therefore, there is an urgent need for an improved technology to solve this problem in the prior art. Contents of the invention [0003] The purpose of the invention is to provide an oxidati...
