Plasma-facilitated photocatalytic purification device and purification method

Abstract

The invention discloses a plasma-synergized photocatalytic purification device and a plasma-synergized photocatalytic purification method. The plasma-synergized photocatalytic purification device comprises a box body, a filter layer, a plasma layer and a photochemical layer, wherein a passage communicated with the two ends of the box body is formed inside the box body; the filter layer, the plasma layer and the photochemical layer are sequentially fixed into the passage; the photochemical layer comprises an UV optical layer and a catalyst layer; the UV optical layer is positioned on one side, facing the filter layer, of the photochemical layer; the catalyst layer is positioned on one side, back from the filter layer, of the photochemical layer. The plasma-synergized photocatalytic purification device has the advantages and beneficial effects as follows: the plasma-synergized photocatalytic purification device is simple in structure and low in using cost, and can greatly reduce or even completely eliminate organic pollutants in waste gas emitted in a factory and discharge water and carbon dioxide which are harmless to the environment, so that the environmental protection level of the factory is improved, the environment around the factory is avoided from being damaged by the organic pollutants, and the body health of residents around the factory is protected.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a plasma cooperative photocatalytic purification device and a purification method. Background technique [0002] Exhaust gas refers to the poisonous and harmful gas emitted by human beings in the process of production and life. Especially in chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted is very smelly, which seriously pollutes the environment and affects human health; while organic pollutants are one of the most harmful gases in the exhaust gas. Pollutants refer to pollutants composed of natural organic substances in the form of carbohydrates, proteins, amino acids, and fats, and some other biodegradable synthetic organic substances; the existing technologies for the treatment of organic pollutants mainly It is through physical adsorption or electrostatic adsorption, but the above methods ha...

Problems solved by technology

Especially in chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, etc., the exhaust gas emitted is very smelly, which seriously pollutes the environment and affects human health; while organic pollutants are one of the most harmful gases in the exhaust gas. Pollutants refer to pollutants composed of natural organic substances in the form of carbohydrates, proteins, amino acids, and fats, and some other biodegradable synthetic organic substances; the existing technologies for the treatment of organic pollutants mainly It is through physical adsorption or electrostatic adsorption, but the above methods have a limited degree of treatment of organic pollutants and high operating costs. Therefore, ordinary factories generally abandon the above methods and directly discharge the exhaust gas to the outside, causing damage to the surrounding environment and the health of residents. cause damage
