Embodiment 1

[0016] The modularly assembled plate-type photocatalytic reaction device of the present invention includes a catalytic reactor, a light source system and a catalyst carrier component.

[0017] The catalytic reactor is a plate-type box, made of a U-shaped tank body 3 made of mirror stainless steel plate, and the two sides are covered with a quartz glass plate 1, and a U-shaped sealing rubber plate is sandwiched between the U-shaped tank body 3 and the quartz glass plate 1, The quartz glass plates on both sides are clamped and fixed by several fasteners 2 to form a plate-type box of the catalytic reactor; several liquid extraction tubes 14 with openings at both ends are placed in the catalytic reactor box in an inverted L shape through the mesh fixing plate 4 In the body, one end of the air delivery pipe 9 is connected to the air pump 7 through the air control valve 15, and the other end is connected to the air release head 8, and the air release head is suspended in the liquid e...

Embodiment 2

[0024] The TiO on the surface of the glass fiber matrix mesh sheet 2 The photocatalytic material is TiO doped with Ag nanoparticles 2 Thin film catalyst:

[0025] The conditions are as follows: tetra-n-butyl titanate is used as titanium source, nitric acid and acetylacetone are used as hydrolysis inhibitors, deionized water is used as hydrolysis agent, and polyethylene glycol and 1,5-pentanediol are additives.

[0026] Pipette 4 ml of tetra-n-butyl titanate, dissolve it in 1 ml of acetylacetone and stir for 0.5 hour to prepare solution A. Another solution B was obtained by dissolving 1 g of polyethylene glycol, 0.25 g of 1,5-pentanediol, and 0.7 g of water in 32.5 ml of ethanol. Solution B was slowly added dropwise to solution A and stirred for 1 hour, and an appropriate amount of concentrated nitric acid was added to adjust the acidity to obtain a precursor sol.

[0027] Immerse the glass fiber matrix mesh in the prepared sol, and finally, put it in a muffle furnace and bake...

Abstract

The invention discloses a modularly assembled plate type catalysis reaction device and a modularly assembled plate type catalysis reaction method. By the adoption of a modular assembling working mode of a plate type reactor and an ultraviolet component, a photocatalytic oxidation system with an electric-charge-free environment-friendly treatment technology in which solar photovoltaic power generation, pneumatic water circulation, oxygen enrichment, natural light and solar energy are coordinated and which serves as a characteristic has the practical characteristics of simple structure, convenience and quickness in assembling, energy conservation and high efficiency. The reactor is combined with multiple units of the ultraviolet component, so that the application range of the system process and the land is enlarged (multi-stage reaction of different factors, application of irregular working lands and the like). The modularly assembled plate type catalysis reaction device is suitable for water treatment application in industry and agriculture and is further suitable for water quality purification in environment-friendly, aquacultural and green landscape water areas.

Description

technical field [0001] The invention relates to a modularly assembled plate-type photocatalytic reaction device and method, specifically a continuous water purification process combining a plate-type photocatalytic reactor and a UV-LED lamp panel module, belonging to the technical field of photocatalytic reaction equipment and Application fields of ultraviolet / visible light-responsive photocatalysts. Background technique [0002] Photocatalytic treatment of environmental pollution is a green technology with broad application prospects. At present, there is more attention in the world, mainly because it is efficient, fast, cheap and environmentally friendly. Its advantages are mild reaction conditions, easy operation, and Direct use of sunlight. Photocatalysis can convert the light energy existing in nature into the energy required for chemical reactions, relying on semiconductor materials to effectively absorb light energy to produce photogenerated electrons and holes with ...
