Abstract

The invention provides a detection apparatus and a detection method for a photocatalyzed gas degradation rate. The apparatus comprises a completely sealed detection box; the top of the detection box is provided with an openable transparent box cover, the side wall of the detection box is provided with a self-sealing cable interface, an inlet valve and an air pressure balancing valve, a multifunctional rack is arranged in the detection box, a gas detector and ultraviolet lamps are fixed on the top of the multifunctional rack, an elevating sample bench is slidably connected onto the multifunctional rack below the gas detector, a convection blower is fixed at one side of the multifunctional rack, and the gas detector is connected with a computer arranged out of the detection box through a transmission cable passing through the self-sealing cable interface. The photocatalyzed gas degradation detection apparatus and the method provided in the invention have the advantages of a broad detection scope, high detection precision, good repeatability of results and capacity of obtaining a continuous smooth variation curve of gas content and time, are applicable to detection of gas degradation under photocatalysis and can accurately and conveniently evaluate degradation capability of photocatalyst products to gas.

Description

technical field [0001] The invention relates to the technical field of photocatalysts, in particular to a detection device and a detection method for the gas degradation ability of photocatalyst air purification products. Background technique [0002] With the development of social economy, the rapid development of industry, the rapid expansion of population, and the increasingly serious pollution, the environment on which people live is deteriorating. A large number of "sick buildings" caused by the decline in air quality, as well as "Sick Building Syndrome", "Building Related Illness" and "Multi-chemical Sensitivity" (Multi-chemical Sensitivity) ) is increasing in number. People have found that due to the widespread use of new building materials, especially chemically synthesized building materials, high-end furniture and household appliances have entered homes and offices one after another, and spices, cosmetics, insecticides and detergents have become indispensable in p...
