Description

High Efficiency Baffled Photocatalytic Reactor

technical field

The utility model relates to a device for treating waste water, in particular to a high-efficiency baffle photocatalytic reactor.

Background technique

Water is an indispensable material resource in human life and production activities. Water resources are discarded and discharged due to loss of use value during use. This kind of water is called wastewater. my country is a country that lacks water resources. If the wastewater is discharged directly without treatment, it will not only waste water resources, but also put a huge pressure on the environment, posing a potential threat to people's lives. The existing waste water treatment device does not have a good treatment effect on waste water, and it still pollutes the environment after being discharged outside.

Photocatalysis is a kind of chemical reaction that can not change itself under the irradiation of light, but can promote chemical reactions. Photocatalyst (such as TiO ₂ ) will generate "electron-hole" pairs after being irradiated by ultraviolet light. Holes have a strong ability to capture electrons. After encountering water molecules, water molecules are deprived of electrons to form hydroxyl radicals (OH). Hydroxyl has strong chemical activity. It can destroy the chemical bonds of organic substances and gradually oxidize them into Low-molecular intermediate product to achieve the purpose of mineralizing and decomposing organic pollutants. The use of photocatalytic technology to treat wastewater can degrade or even completely mineralize pollutants in the water body, and realize the harmless treatment of wastewater.

Contents of the invention

The purpose of the utility model is to provide a high-efficiency baffle photocatalytic reactor, which is suitable for solving the problem that the existing wastewater treatment device cannot effectively realize the harmless treatment of wastewater.

The technical scheme adopted by the utility model to solve the technical problem is: the casing of the high-efficiency baffle photocatalytic reactor is equipped with circular baffles, and the circular baffles are staggered to form a continuous The curved flow path; the ultraviolet lamps respectively extend into the shell from both ends of the shell and pass through the circular baffle; the feed port is set at one end of the shell, and the discharge port is set at the other end of the shell.

In the above solution, there are two groups of ultraviolet lamps, and each group of ultraviolet lamps is arranged in an equilateral triangle; one group of ultraviolet lamps protrudes into the housing from one end of the housing, and the other group of ultraviolet lamps protrudes into the housing from the other end of the housing.

The utility model has the following beneficial effects:

1. The utility model has a compact structure, and the staggered round and segment-shaped baffles can make the wastewater forward in a deflected manner. Even if there is no stirring device inside the utility model, the violent turbulence of the wastewater can be realized, so that the wastewater can fully integrate with the ultraviolet light. Contact, under the catalysis of ultraviolet light, and use liquid oxidant or water-soluble solid oxidant to remove toxic organic pollutants that are difficult to degrade in the water body, and realize the harmless treatment of wastewater.

2. In the utility model, the ultraviolet lamps are arranged in an equilateral triangle, which further strengthens the contact between the waste water and the ultraviolet light.

Detailed ways

As shown in Figure 1, this high-efficiency baffle type photocatalytic reactor has a shell 2, and the feed inlet 1 is arranged on one end of the shell 2, and the discharge port 5 is arranged on the other end of the shell 2; There are round-shaped baffles 3 installed inside, and the round-shaped baffles 3 are staggered to form a continuous curved flow channel. Refer to Figure 2. The round-shaped baffles 3 have an arc segment, and the round The shape baffle 3 is fixed on the inner wall of the housing 2 through an arc segment. The ultraviolet lamps 4 extend into the housing from both ends of the housing 2 and pass through the circular baffles 3. The circular baffles 3 support the ultraviolet lamps 4; there are two groups of ultraviolet lamps, each The groups of ultraviolet lamps 4 are arranged in an equilateral triangle; one group of ultraviolet lamps 4 protrudes into the housing 2 from one end of the housing, and the other group of ultraviolet lamps 4 protrudes into the housing 2 from the other end of the housing.

The waste water to be treated enters the reactor shell 2 through the feed port 1, the switch of the ultraviolet lamp 4 is turned on, and the waste water to be treated in which the oxidant is dissolved is introduced into the reactor, and the waste water is deflected and forwarded along the circular baffle baffle 3, The baffle plate divides the reactor into several reaction chambers connected in series. The waste water flows through the ultraviolet lamp 4 in each reaction chamber. The flow velocity and flow direction of the waste water are constantly changing. The photodegradation reaction is carried out under the catalysis of ultraviolet light, the pollutants in the waste water can be effectively degraded and removed, and the purified water after the reaction is discharged from the reactor through the discharge port 5 .
