Problems solved by technology
However, precious metals are easy to be poisoned, deactivated, raw materials are scarce, and the price is high, which restricts the application of noble metal catalysts
Due to the low activity of non-precious metals, the temperature for complete degradation of organic pollutants usually needs to be above 300°C, which increases energy consumption
Moreover, the reaction at a higher temperature will easily lead to the sintering deactivation of the catalyst, which has higher requirements on the structural strength of the catalyst.
However, the photocatalytic reaction rate is low, and it is only suitable for treating low concentrations of organic pollutants.

The invention discloses a light-heat synergistic industrial organic waste gas treatment device and method. The device mainly includes a catalytic reaction chamber, a preheating system and a reflector adjustment device. Sunlight is projected into the preheating system and the catalytic reaction chamber for gas preheating and to stimulate the photocatalytic activity of the catalyst. The reflector adjustment device can automatically adjust the angle of the reflector according to the incident angle of sunlight, so that more sunlight can shine on the catalyst. Industrial organic waste gas enters the catalytic reaction chamber through the preheating system, and the organic waste gas flows through the catalyst film in the catalytic reaction chamber. The catalyst on the catalyst film is subjected to the dual action of light and external heating to catalyze the oxidation of organic waste gas to generate CO 2 and H 2 O, to achieve the removal of organic pollutants.
Description
technical field [0001] The invention relates to a photo-thermal synergistic reaction device for catalytic oxidation of industrial organic pollutants, which belongs to the field of environmental protection. Background technique [0002] The petrochemical industry is one of the most important discharge sources of industrial organic pollutants in my country, and has the characteristics of large discharge, high concentration, and complex components. Oxidative degradation is the conversion of organic pollutants into CO using oxygen in the air 2 and H 2 O is also the most concerned organic pollutant degradation technology. Using suitable catalysts for catalytic oxidation can reduce the oxidation reaction temperature of organic pollutants, thereby further reducing energy consumption. However, precious metals are easy to be poisoned and deactivated, raw materials are scarce, and the price is high, which restricts the application of noble metal catalysts. Due to the low activity ...
