Multi-tower-plate stream distribution in-diffusion vertical plug-flow photocatalysis reactor

Abstract

The invention relates to a multi-tower-plate stream distribution in-diffusion vertical plug-flow photocatalysis reactor. A modulator tube of a quartz socket tube is attached to the lining of the multi-tower-plate stream distribution in-diffusion vertical plug-flow photocatalysis reactor, the quartz socket tube is coaxial to the reactor, tower plates which are in a spiral rising shape and of which the axle is the quartz socket tube are arranged from the bottom to the top of the reactor, multiple catalyst trays are hung on the space between an upper tower plate and a lower tower plate, water inlets are formed at the lower portion of the photocatalysis reactor, and a water outlet is formed at the upper portion of the photocatalysis reactor. Through the coordination of the multiple spiral tower plates in the photocatalysis reactor and the catalyst trays which are hung between the multiple tower plates and are distributed in a spiral shape, the multiple spiral tower plates play an effect of guiding water streams, so that catalysts in the catalyst trays fully react with sewage, and thus the photocatalysis reaction efficiency is improved. The multi-tower-plate stream distribution in-diffusion vertical plug-flow photocatalysis reactor is simple and reasonable in structure, convenient to assemble and disassemble, is convenient to adjust and clean, low in operation maintenance cost, diversified in dirt removing variety, high in efficiency, stable in operation, simple in management, and is applied to treatment of various kinds of waster water.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a vertical push-flow photocatalytic reactor with flow distribution and internal diffusion on multiple trays. Background technique [0002] The photocatalytic reactor is the place where the photocatalytic reaction occurs, and the design of an efficient and easy-to-use reactor plays a very important role in the scientific research and practical application of the photocatalytic reaction. Since the 1980s, heterogeneous photocatalysis of nano-semiconductor materials has gained more and more attention in the field of environmental protection. The photocatalytic reaction can carry out a deep reaction at room temperature, completely mineralize and remove a variety of organic pollutants, especially in the removal of toxic and harmful substances that are difficult to biodegrade, and is considered to be a very promising Environmental pollution deep purification technology. As a place where p...

Problems solved by technology

[0003] The various reactors mentioned above have their own advantages and design purposes, but there are also problems such as low utilization rate of light source energy, small contact area between catalyst and reaction liquid, insufficient utilization of catalyst, difficulty in recycling, and low treatment efficiency and effect. Waiting for the disadvantages

Moreover, due to the low reaction efficiency of existing photocatalytic reactors and the small amount of water to be treated, photocatalytic reactors have always been limited to laboratory research. After scale-up, the efficiency and effect of wastewater treatment cannot meet the actual requirements, and it is difficult to used in industrial production
