Embodiment Construction

[0011] The invention includes an ozone+ultraviolet photocatalyst reaction stage (2), a nanosphere air purification stage (8), and a biological dripping filter stage (12), which are completed by two box devices. This system takes 20000m 3 / h as an example, in figure 1 Among them, the ozone + ultraviolet photocatalyst reactor is connected to the front air intake pipe through the flange (1), and two paint mist filters (3) are installed at the air intake end to remove most of the paint mist in the exhaust gas and prevent the paint mist from passing through. into the follow-up reaction device, resulting in clogging of the filter or reducing the brightness of the ultraviolet lamp. According to the concentration of paint mist in the exhaust gas, the paint mist filter needs to be replaced regularly. Exhaust gas passes through 16 photocatalyst filter screens (6) after removing a large amount of paint mist through the paint mist filter screen. In the compartment of the photocatalyst f...

Abstract

The present invention discloses a new waste gas treatment system. A purpose of the present invention is to provide a treatment process for overcoming defects in the prior art and achieving a good waste gas purification effect. The system comprises an ozone and ultraviolet photocatalyst purification device, an air nanometer sphere purifier and a biological trickling device. With the system of the present invention, the decomposition on the organic waste gas can be well completed, the investment cost and the operating cost are substantially reduced, and the risk of burning generation during the active carbon desorption process is avoided. The system of the present invention is suitable for treatment of all organic waste gas having medium-low concentrations.

Description

technical field [0001] The invention relates to the technical field of industrial waste gas treatment, in particular to the treatment of organic gas produced in printing, dyeing and painting industries. Background technique [0002] At present, the method of activated carbon adsorption + catalytic combustion regeneration is used for the organic waste gas generated in industry. Generally, two adsorbers are required to alternately switch operation, the process is complicated, and the investment and operation costs are high. Catalytic combustion regeneration uses precious metals (platinum, rhodium) as catalysts, and the combustion temperature is above 250°C, so the regeneration heating requirement is above 300°C, while the ignition point of activated carbon is 600°C, and the activated carbon releases heat during adsorption, so both adsorption and regeneration are on fire. risk. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned p...
