Problems solved by technology

Due to the low flow rate, small Reynolds number, and laminar flow state of the fixed photocatalytic reactor, there are disadvantages such as mass transfer limitation and high energy consumption; at the same time, the reactor is not closed, and the catalyst is greatly affected by the surrounding environment , can easily cause catalyst poisoning
The packed bed photocatalytic reactor is filled with TiO 2 Particle or surface coated with TiO 2 The silica gel, alumina and quartz sand of the membrane have high mass transfer capacity; however, the collision between particles will cause the membrane to fall off, so it is not necessary to use long-term operation
The mixed solution of catalyst particles and pollutants in the suspension photocatalytic reactor is in a turbulent state, without mass transfer restrictions; at the same time, the reactor is in a closed state, and there is no problem of evaporation of volatile pollutants; however, there are catalyst separation and recovery, repeated The problem of utilization, therefore, how to realize the separation, recovery and recycling of the catalyst is the main problem faced by the suspension photocatalytic reactor

Abstract

The invention provides a solar automatic tracking photothermal catalysis-membrane separation reaction system. area, solar power generation area. The TiO2 catalyst is fully mixed with the pollutants through the aeration and mixing driving method, so as to promote the circulation of the mixed liquid to carry out the photothermal catalytic reaction. Driven by the solar automatic tracker, this system can track sunlight all day long, and has high light energy utilization rate and mass transfer efficiency. The setting of the solar automatic tracker greatly improves the efficiency of photothermal catalytic reaction to remove pollutants. Maximize the utilization of light energy; the electric energy provided by the solar power generation area can meet the power required by the entire system, so that the system can get rid of the shackles of external power supply, and truly achieve high efficiency, energy saving, and self-sufficiency.

Description

technical field [0001] The invention relates to a photothermal catalysis reaction system, which is a sunlight automatic tracking photothermal catalysis-membrane separation reaction system. The invention is a photocatalytic oxidation wastewater treatment device which is not affected by the weather. The device can be applied not only to the pretreatment or advanced treatment of toxic, harmful and refractory organic wastewater, but also to the advanced treatment of slightly polluted drinking water. Background technique [0002] Energy shortage is a very serious problem facing the world. As a clean and pollution-free new energy source, solar energy has a very broad development prospect. With the research on the large-scale development and utilization of solar energy, it is found that the daylighting rate and The photoelectric and photothermal conversion rates are low; the use of solar automatic trackers can make the solar lighting panels always perpendicular to the sunlight, mai...
