Abstract

The invention relates to an integrated purification device for gaseous pollutants. The device comprises a reactor body, a high-voltage electrode, a grounding electrode and a power supply system, wherein a gas inlet is formed in the lower part of the reactor body, and a gas outlet is formed in the upper part of the reactor body; the high-voltage electrode is arranged in a position of a longitudinal central line of the reactor body, and the grounding electrode is arranged on a casing of the reactor body; an overflow groove is formed in the upper part of the inner side of the reactor body, and a wind distribution plate is arranged at the lower part of the inner side of the reactor body; a drainage port is formed in the bottom of the reactor body; a plurality of through holes which are taken as water inlets are uniformly formed in a wall, above the overflow groove, of the reactor body; the high-voltage electrode is connected with an output end of the power supply system through a high-voltage lead; and the grounding electrode is connected with a grounding end of the power supply system through a grounding lead. According to the integrated purification device for the gaseous pollutants, innocent treatment of various pollutants in exhaust gas can be performed in the purification device simultaneously, the efficiency is improved, and generation of secondary pollution is prevented at the same time.

Description

technical field [0001] The invention relates to a device for synergistically removing multiple pollutants, in particular to an integrated purification device for gaseous pollutants, which belongs to the field of environmental protection. Background technique [0002] With the continuous growth of industrial development and energy consumption, the problem of air pollution in our country is becoming more and more serious, which has aroused widespread concern from all walks of life. Atmospheric pollutants in my country mainly come from waste gas from thermal power, petrochemical, painting, pharmaceutical, water treatment and pharmaceutical industries, including nitrogen oxides (NO x ), sulfur dioxide (SO 2 ), dust (PM), heavy metals (such as mercury, lead, etc.) and volatile organic compounds (VOCs), etc., have the characteristics of large quantity, wide area and complex composition. If they are directly discharged, they will have a serious impact on the atmospheric environmen...
