Problems solved by technology
Among them, the combination of the two has the best effect. The combination of the stirring device and the aeration device often causes the aeration system to be unstable in traditional equipment, resulting in unstable pressure in the reaction chamber, resulting in a decrease in photocatalytic efficiency, and the light source is prone to overheating. High and damaged, shortening the service life of the light source

The invention provides a photocatalytic sterilization reactor. The reactor comprises a stirring device, a reaction chamber, an LED light source, a cold trap, a UV lamp, a power supply, and an aeration plate; the left side of the cold trap is provided with a water inlet, the right side of the cold trap is provided with a water outlet; the LED light source is arranged in the cold trap; the UV lamp is arranged on the right side of the stirring device; the power supply is connected to the UV lamp, the aeration plate is arrange in the bottom of the reaction chamber; and an air outlet is arranged in the upper end of the reaction chamber. The cold trap can prevent the destruction caused by high temperature of LED lamp tube; the UV lamp can kill bacteria; the aeration plate and the stirring device can make solution be mixed more fully and rapidly, the reaction time is shortened therefore, and the photocatalysis efficiency is improved at the same time.
Description
technical field [0001] The invention relates to the field of reactors, in particular to a photocatalytic sterilization reactor. Background technique [0002] Photocatalytic reaction is a kind of photocatalysis under the irradiation of light, which uses the light energy generated by the light source to convert the energy required for chemical reactions to produce catalysis and speed up the reaction rate. Photocatalytic reactors can be divided into fluidized photocatalytic reactors and solid-state photocatalytic reactors according to the form of catalyst. At present, fluidized photocatalytic reactors are widely used in the fields of chemical industry, food and medicine. There are three main fluidization methods for fluidized photocatalytic reactors, one is through stirring, the other is through aeration, and the other is a combination of both. Among them, the combination of the two has the best effect. The combination of the stirring device and the aeration device often cause...
