A tubular reactor for catalytic oxidative degradation of wastewater

By introducing annular degradation tubes and a pusher plate structure into a tubular reactor, the catalyst particles are driven to move circumferentially. The piston and elastic rope design solves the problems of clogging and incomplete degradation caused by the multi-layer arrangement of catalytic units, thus achieving efficient wastewater treatment.

AI Technical Summary

Technical Problem

The multi-layered arrangement of catalytic units in existing tubular reactors increases costs, wastewater passes through the catalytic units rapidly but cannot be effectively degraded, and catalyst particle accumulation leads to progressive clogging.

Method used

The system employs a ring-shaped degradation tube and a pusher plate structure. The pusher plate propels the catalyst particles in a circumferential motion. Combined with the design of a piston and elastic rope, this achieves the collision and agitation of the catalyst particles and wastewater, extending the contact time, preventing clogging, and improving reaction efficiency.

Benefits of technology

It prolongs the contact time between catalyst particles and wastewater, improves the degradation effect per unit time, avoids catalyst particle accumulation and blockage, and enhances the uniformity and efficiency of the reaction.

Abstract

The application discloses a tubular reactor for catalytic oxidative degradation of wastewater, which is characterized by the following technical scheme: a ring-shaped degradation tube is arranged on a water inlet pipe, and the inner cavity of the degradation tube is divided into four separate degradation chambers by four push plates, so that when the push plates move, the catalyst particles in the degradation chambers can be pushed to move in the circumferential direction, wastewater enters the single degradation chamber and is pushed to move in the circumferential direction together with the catalyst particles, the contact time of the catalyst particles in the single degradation chamber with the wastewater is prolonged, the pushed catalyst particles roll and efficiently contact with the wastewater, and thus the degradation effect per unit time is improved.
