Deodorization device and method for removing high-concentration foul gas and VOC waste gas

Abstract

The invention discloses a deodorizing device and method for removing high-concentration malodorous gas and VOC waste gas, wherein the deodorizing device includes a vacuum ultraviolet light reaction chamber and a carbon-manganese mixed filter tower connected in sequence; the vacuum ultraviolet light reaction chamber One or more chambers are connected in parallel, which includes a reaction chamber and an air inlet and an air outlet connected to the reaction chamber, the air inlet is connected to the gas supply end; the carbon-manganese mixed filter tower includes a tower body And the inlet of the filter tower and the outlet of the filter tower connected with the tower body, the outlet of the filter tower is connected with the discharge end, and the air outlet is connected with the inlet of the filter tower. The wavelength of the VUV lamp group in the VUV reaction chamber is 185nm, or a combination of 185nm and 254nm to form a dense and effective ultraviolet light region. This reaction chamber provides sufficient reaction time of 3 to 4 seconds, so that the malodorous organic gas can quickly enter the reaction chamber. oxidation. Regardless of high concentration or low concentration of malodorous gas, when it enters the light area, it will be fully irradiated and quickly oxidized to avoid gas escape or short circuit, and the effective removal rate can reach 99%.

AI Technical Summary

Benefits of technology

In this patented technology, there were two ways for removing bad smells from exhaust gases: one was by combining both methods like UV lamp reactors and filters; another method involves adding an active agent called coked coal (C) instead of pure nitrogen dioxide (NO2) used alone. These techniques resulted in better efficiency compared to traditional treatments such as hydrolysis treatment.

Problems solved by technology

This patents discuss different technical problem addressed by previous inventions related to treating harmful gases generated from industrial processes like manufacturing plants. Prior solutions were either expensive or had limitations due to their lack of effective degradative effects against certain types of pollutants. There needs improvement over current techniques without compromising its efficiency and safety aspects.
