Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.
It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the invention pertains.
As shown in fig. 1, an embodiment of the present invention provides a photo-electro-catalytic rf heating sterilizer, including: the device comprises a shell 1, an exhaust fan 4, a photoelectric catalyst net 5, a light source 6, an electrode 7, a radio frequency generator 8 and a filter screen 9.
The housing 1 has therein an air inlet 2 and an air outlet 3 communicating through an air passage. The exhaust fan 4 is disposed in the exhaust port 3.
Two photoelectric catalyst nets 5 are arranged and divided into a positive electrode net and a negative electrode net, the two photoelectric catalyst nets 5 are arranged in the air passage at intervals along the extending direction of the air passage, the distance between the two photoelectric catalyst nets 5 is 50-200mm, and in the embodiment, the distance between the two photoelectric catalyst nets 5 is 80 mm. The photoelectric catalyst net 5 comprises a frame carrier and a photoelectric catalyst covered on the surface of the frame carrier, and the frame carrier is made of a conductive material. The frame carrier can adopt one of copper mesh, copper foam, activated carbon mesh, activated carbon fiber mesh, titanium dioxide mesh or titanium foam for loading the photoelectric catalyst. The photoelectric catalyst is ZnO-Cu2O-g-C3N4/TiO2。
In this example, the frame carrier was made of a 100 mesh titanium dioxide mesh having a size of length x width x thickness of 399mm 299mm 2mm, which was immersed in a 0.2M oxalic acid solution for 2 hours. Then at 40 ℃ with a 0.2M concentration of K2MnO4Soaking in water solution for 0.5h, taking out, standing for 24h, and washing with water until the pH of the water washing solution is not less than 6.5. Then, the 100 mesh titanium dioxide net was loaded with ZnO, Cu2O, and g-C3N4 photocatalyst precursors.
The preparation process comprises the following steps: dissolving tetrabutyl titanate 30ml in anhydrous ethanol 100ml, adding diethanolamine 10ml, melamine 10g and Zn (NO) 2g respectively after stirring3)2·6H2O and 6g of CuNO3·5H2And O is ethanol mixed solution, and the mixed solution is stirred for 2 hours at the temperature of 60 ℃ to obtain mixed colloidal solution. Then coating the colloidal solution on the surface of the pre-treated 100-mesh titanium dioxide net by using a brush, naturally drying, then coating for many times, finally standing for 24 hours at 35 ℃ in an ultrasonic vacuum manner, and finally drying the catalyst-coated 100-mesh titanium dioxide net for 2 hours at 110 ℃.
Then roasting at 550 ℃ for 2h, taking outThereafter, the surface of the titanium dioxide net of 100 mesh was ground with a fine gauze, 100g of copper sulfate pentahydrate and 150g of sodium potassium tartrate were dissolved in 400mL of cold water, respectively, and the two were mixed while the solution was cooled to room temperature, and the titanium dioxide net was put into the solution (about 800 mL). 75g of sodium hydroxide was dissolved in 200mL of water to prepare an alkali solution.
