Abstract

The invention provides a matrix type combined oxidation regeneration device, which is composed of multiple small oxidation regeneration towers. The oxidation regeneration device is characterized in that multiple small oxidation regeneration towers are parallelly arranged in M rows. Each row is a multistage oxidation regeneration device formed by serially connecting N small oxidation regeneration towers. Each multistage oxidation regeneration device comprises first to Nth small oxidation regeneration towers. The first small oxidation regeneration tower is connected to the outlet pipe of an absorption tower. Two neighbored small oxidation regeneration towers are connected by an overflow pipe. The bottom of the first small oxidation regeneration tower is connected to a filtering machine through a primary sulfur slurry pump. The bottoms of other small oxidation regeneration towers are connected to the first small oxidation regeneration tower or a previous small oxidation regeneration towerthrough a sulfur slurry pump. The Nth small oxidation regeneration tower is connected to the barren liquor inlet pipe of the absorption tower through a barren liquor pump.

Description

technical field [0001] The invention relates to a matrix-type combined oxidation regeneration device, which is particularly suitable for oxidation regeneration of iron catalysts in a liquid-phase oxidation-reduction double-tower desulfurization process. Background technique [0002] The traditional liquid-phase redox double-tower desulfurization process (LO-CAT process) mainly includes an absorption tower, an oxidation regeneration device, and usually includes a sulfur slurry concentration and purification device. See the attached system diagram figure 1 . Wherein the existing designs of the oxidation regeneration device are as follows: 1. A large capacity oxidation regeneration device is adopted, but its disadvantages are: the operation flexibility is small, and it is difficult to skid. 2. The simple parallel connection of multiple small-capacity oxidation regeneration devices is used. The disadvantages are: the number of supporting pumps and flow control valve groups is ...
