Novel electrolysis technology and system for VOCs

Abstract

The invention relates to the field of atmospheric treatment, in particular to a novel electrolysis technology for VOCs. The technology comprises the following three technological processes: an absorption process of the VOCs: continuously introducing VOCs gas, and enabling the VOCs to enter a gathering box to be absorbed by absorption liquid; secondly, an electrolysis process of the VOCs, wherein the gas enters an electrolytic tank of an electrolytic tower through a pipeline, a large number of hydroxyl free radicals with strong oxidizing properties can be generated through an electrolytic reaction of an anode and a cathode under the action of a certain catalyst, the VOCs in a solution can be oxidized into soluble intermediate substances, carbon dioxide, water and other small molecular products by the hydroxyl free radicals, and in addition, a large amount of nanometer foam exists between the cathode and the anode so as to slow down the flowing speed of VOCs in the solution and enhance the electrolysis efficiency of gas; and a circulation process of the absorption liquid: enabling the electrolyzed absorption liquid to pass through a filter plate and a filter screen of the electrolysis tower, and then return to a VOCs gathering box again under the action of a one-way circulating pump for recycling. Thus, the cost of replacing the solution multiple times is reduced.

Description

technical field [0001] The invention belongs to the application field of atmospheric treatment technology, and in particular relates to a novel electrolysis VOCs technology and system. Background technique [0002] Volatile organic compounds (VOCs, volatile organic compounds) have many definitions. According to the definition of the World Health Organization (WHO), VOCs are various organic compounds with a boiling point of 50°C to 260°C at room temperature. It is usually divided into non-methane hydrocarbons, oxygen-containing organic compounds, halogenated hydrocarbons, nitrogen-containing organic compounds, and sulfur-containing organic compounds. VOCs play an important role in air pollution. Most VOCs are toxic and will directly endanger human health, cause adverse effects on the human body, damage internal organs and nervous system, and cause acute poisoning or even cancer in severe cases. Therefore, the state's supervision on waste gas has increased, and the emission s...
