Wet-process all-component waste gas purification tower, purification system and purification method

Abstract

The invention provides a wet-process all-component waste gas purification tower, a purification system and a purification method. The wet-process all-component waste gas purification tower comprises atower body and one or more absorption liquid circulation systems, each absorption liquid circulation system comprises an absorption liquid preparation system, a reaction system and an absorption liquid recovery system, and each reaction system comprises N layers of tower plates horizontally arranged in the tower body; the outer diameter of the Nth layer of tower plate is matched with the inner diameter of the tower body to realize radial plugging of the tower body, an overflow port is formed between the 1-(N-1)th layer of tower plate and the inner wall of the tower body, and an overflow weiris arranged at the overflow port of the tower plate; a plurality of bubble cap units are arranged on the tower plate, each bubble cap unit comprises a riser and a bubble cap, and the upper edge of theoverflow weir is higher than the upper edge of the bubble cap; a circulating liquid outlet of the absorption liquid circulating system is communicated with the absorption liquid on the first layer oftower plate, and the absorption liquid on the Nth layer of tower plate is communicated with a circulating liquid inlet of the absorption liquid circulating system. The wet-process all-component wastegas purification tower is wide in application range, small in occupied space, good in purification effect and suitable for purification treatment of various waste gases.

Description

technical field [0001] The invention relates to waste gas treatment technology, in particular to a wet-process full-component waste gas purification tower, a purification system and a purification method. Background technique [0002] Since the 21st century, the rapid development of industry and transportation, the continuous expansion of cities and the high concentration of population have made air pollution more and more serious. At present, more than 600 million tons of harmful gases and more than 100 million tons of coal dust and other dust are discharged into the atmosphere every year in the world, seriously polluting the atmosphere and posing a threat to human health. [0003] Air pollutants refer to those substances that are discharged into the atmosphere due to human activities or natural processes and have harmful effects on humans or the environment. There are many types of air pollutants, which can be divided into aerosol pollutants and gaseous pollutants accordi...
