Description
Technical field
The wood utility model relates to a kind of experimental provision, and in particular, it relates to a kind of closed photocatalysis experimental box.
Background technology
Along with the expansion of social production scale and being extensive use of of various chemicals, poisonous and harmful and difficult degradation decomposed substance contained in the sewage of discharging are more and more.For these pollutants, adopt traditional physics method (as burying), chemical method (as ozone oxidation) and biological method (as active sludge) etc. to handle, these methods exist pollutant still in problems such as ecosphere circulation, fluctuation of service and operating cost height to a certain extent.
Photocatalysis degradation organic contaminant is extensive at the laboratory area research at present, but still can't large-scale practical application.And in the laboratory study process, owing to equipment therefor differs greatly, different researchers, the evaluation means difference causes that the catalytic capability of photocatalyst is not had unified evaluation criterion and standard, seriously restricts the development of photocatalysis technology.Generally, exist the temperature of reaction solution under illumination to rise in the photocatalysis apparatus and the disunity of light source wave band, seriousness and accuracy that this two large problems influence is tested.
The utility model content
The purpose of this utility model is to provide a kind of closed photocatalysis experimental box, and it adopts air-cooled and water-cooled guarantees that temperature of reaction is constant, can carry out combined type and filter, and can carry out the active testing of various photocatalysts.
The technical scheme in the invention for solving the technical problem is: a kind of employing is air-cooled and water-cooled assurance temperature of reaction is constant, carries out combined type and filters, and can carry out the closed photocatalysis experimental box of the active testing of various photocatalysts.It comprises: a Stainless Steel Shell (1) is fixed on the fan (2) at top; Light source (3) at the fan end opening; Light source positioned beneath multilayer stainless steel separator, optical filter (4) is placed in the hole in the existence; Bottom of device is laid magnetic stirrer (5), and cooling bench (6) is installed on it; The outside UNICOM's water pipe (7) of cooling bench, the inner sample cell (8) of placing.It is characterized in that device top installation fan (2), provide air-cooled to the experimental provision internal environment, bottom of device is installed cooling bench (6) provides steady temperature by water pipe (7) flowing water, the assurance temperature of reaction is constant, make the photocatalysis experiment have repeatability, can adjust simultaneously the radiation of the position acquisition different-waveband of multiple optical filter (4) and carry out the combined type optical filtering, thereby can carry out the photocatalytic activity test of various photocatalysts.
The beneficial effects of the utility model are: adopt air-cooled constant with water-cooled assurance temperature of reaction, avoid occurring the violent change of reaction environment system, experiment has repeatability, the position that can adjust simultaneously multiple optical filter obtains the radiation of different-waveband, carries out the photocatalytic activity test of various photocatalysts.
