Abstract

This paper mainly analyzes chemical kinetics simulation of the removal of formaldehyde (HCHO) in atmospheric dielectric barrier discharge, builds a time-space average model, and verifies relevant results through experiment. Changes in concentration of various substances with discharge time are analyzed through chemical experiment. In simulated atmospheric environment, HCHO is mainly removed by free radicals of oxygen ions and hydroxyl ions, among which, hydroxyl ions have stronger force. In chemical kinetics simulation, the first electronically excited state of nitrogen molecules is stressed, and collision of these molecules with oxygen molecules and water molecules has an influence on the concentration of oxygen ions and hydroxyl ions. In nitrogen environment, the first electronically excited state of nitrogen molecules is the main substance for removal of HCHO. This paper discusses about the influence of initial concentration of HCHO and gas flow etc on specific energy consumption of removal of HCHO and molar ratio of CO2/CO among experimental products. When initial concentration of HCHO is inversely proportional to specific energy consumption of removal of HCHO and input energy density is lower than 60J/L and concentration of HCHO is low, molar ratio of CO2/CO among experimental products is high.
