Description

Technical Field

[0001] This utility model relates to the field of Fenton fluidized bed technology, specifically a Fenton fluidized bed reactor. Background Technology

[0002] Fenton fluidized bed reactors are advanced oxidation treatment equipment that combines Fenton oxidation technology with the characteristics of fluidized bed reactors. They are mainly used for the deep treatment of recalcitrant organic wastewater. The core principle is to generate highly oxidizing hydroxyl radicals through the Fenton reaction, while using fluidized bed technology to improve reaction efficiency and achieve efficient degradation of organic pollutants. The fluidized bed principle uses the action of water and gas to keep the particulate carrier in a fluidized state in the reactor. Wastewater enters from the bottom of the reactor and flows upward, while air or other gases are introduced at the same time, forming a three-phase flow of gas, liquid, and solid. The carrier particles continuously roll and collide under the action of the fluid, which increases the mass transfer efficiency and allows the Fenton reaction to proceed more fully.

[0003] Chinese patent discloses a Fenton fluidized bed reactor (authorization announcement number CN213294963U). This patented technology uses an inlet pipe and a guide channel to create a high-speed swirling zone for the water entering the tank. Simultaneously, a stirring assembly mixes the water, generating centrifugal force. Combined with the high-speed swirling zone, the centrifugal force, centripetal force, buoyancy, and fluid drag cause the less dense water to rise, while denser particles such as sand and sludge settle into the grooves, thus preventing clogging of the water distribution filter head. However, the aforementioned Fenton fluidized bed reactor mixes the liquid by rotating in the same direction, with the packing material rotating with the liquid. This results in low mixing uniformity, which is detrimental to the Fenton fluidization reaction rate and affects treatment efficiency. Therefore, those skilled in the art have provided a Fenton fluidized bed reactor to solve the problems mentioned in the background art. Utility Model Content
