Low-temperature plasma waste gas treatment apparatus

Abstract

The invention discloses a low-temperature plasma waste gas treatment apparatus. The low-temperature plasma waste gas treatment apparatus comprises a pretreatment apparatus and a plasma reaction apparatus; the pretreatment apparatus comprises a pre-washing box, a circulating water box and a filtering box body; a water outlet of the pre-washing box is connected with the circulating water box, and a gas outlet of the pre-washing box is connected with the filtering box body; the plasma reaction apparatus is connected with the filtering box body, the gas flowing out from the filtering box body successively passes through a defroster, a dust removal plate and a condensation pipe in the plasma reaction apparatus to be secondarily treated, and the collision times of the waste gas flowing out from the condensation pipe in a pre-ionization plasma apparatus and a low-temperature plasma apparatus is increased. By virtue of the pretreatment apparatus, the gas easy to dissolve and large-particle dust in the gas can be effectively eliminated; and when the waste gas passes through the pre-ionization plasma apparatus and the low-temperature plasma apparatus with a same size and inclined angle in the plasma reaction apparatus, the plasma collision times can be increased, so that the waste gas treatment efficiency is increased. The low-temperature plasma waste gas treatment apparatus has the characteristics of simple structure and low energy consumption.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and relates to a low-temperature plasma waste gas treatment device. 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. The industrial exhaust gas emitted by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without treatment and reaches the standard, it will inevitably reduce the quality of the atmospheric environment, bring serious harm to human health, and cause huge losses to the national economy. Waste gas includes organic waste gas, inorganic waste gas and malodorous waste gas, m...
