The absorption tower is an environment-friendly device for absorbing or purifying pollutants, and the principle is that the pollutants in gas are conveyed into liquid by utilizing the contact of the gas and the liquid, and then the clean gas and the liquid absorbing the pollutants are separated, so that the aim of cleaning the flue gas is fulfilled. But the removal effect on pollutants such as ultrafine particles, particularly PM2.5, acid mist, toxic heavy metals and the like is not ideal. The wet electric dust collector has good removal effect on the pollutants.
Although the wet electric dust collector has a good removing effect on small particles, the purifying effect is still effective, and the particles near 1 micron are in a field charge and diffusion charge mixing area, so that the charging capacity is poor and the particles are difficult to remove. Therefore, in order to improve the wet-type dust remover effect, most manufacturers often set an absorption tower at the front end of the wet-type electric dust remover, and spray treatment is carried out on the flue gas in advance through the absorption tower, so that the flue gas is wetted and then enters the wet-type electric dust remover for treatment, although the effect can be improved, the effect is not obvious, and the threat to the atmospheric environment still exists.
