A Concentrating Enhanced Solar Photocatalytic Reactor

Abstract

The invention discloses a condensation intensified type solar photocatalytic reactor. The reactor comprises two parallel trough type condensation reaction devices which form the height head, a quartz glass reaction tube in each trough type condensation reaction device is placed in the focusing position of a trough type condenser and is supported by a support; heliostat tracking systems are connected with and support the trough type condensers; the two trough type condensation reaction devices are connected through a cooling tube and a circulating tube to form a closed circulating passage; the lower end of the circulating tube is open and connected with a feeding pipe, and the feeding pipe is sequentially connected with a feeding pump and a reaction solution container; the upper end of the circulating tube is open and connected with a T-joint, and the other two ends of the T-joint are connected with a buffer surge tank and a sampling tube respectively. By using the excellent light transmission of the quartz glass reaction tubes, the characteristics of the heliostat tracking systems, the condensing effect of the trough type condensers as well as the secondary light compensation effect of reflectors, the comprehensive utilization efficiency of sunlight is improved, and sufficient sunlight illumination intensity is provided for photocatalytic reactions.

Description

technical field [0001] The invention relates to a concentrating enhanced solar photocatalytic reactor, which is used for photocatalytic degradation of liquid organic pollutants and belongs to the technical field of photocatalysis. Background technique [0002] Environment and energy are major issues that directly affect human survival and development. In recent years, with the rapid development of my country's economy and the improvement of people's living standards, a large number of toxic and refractory pollutants such as chemicals, pesticides, heavy metals and nitrite have entered the environment, especially water resources, resulting in serious water pollution. At present, there is still a lack of effective treatment methods for organic wastewater that is difficult to biodegrade due to technical and economic reasons. As one of the most promising green technologies to solve environmental and energy problems, photocatalysis can not only be applied in the field of environm...

Problems solved by technology

At present, the development and design of different solar photocatalytic reactors are relatively active at home and abroad, but photocatalytic reactors still have problems such as low light source utilization efficiency and mass transfer efficiency, complex devices, and uneven light intensity, which will restrict the development of photocatalytic reactor technology. , while whether the reactor is suitable for practical applications or large batch processing is still a matter of consideration
