The present invention relates to a wet type multilayer and multistage porous plate scrubber which does not need to install or replace the demister, decreases pressure loss, minimizes power consumption, miniaturizes the device, has high efficiency. The present invention comprises: a water spray which sprays water to contaminated air current inhaled from an inlet fan by being installed inside a casing; plurality of plates which are installed by having a space vertically to collect find dust, dust particles, noxious gas inside the contaminated air current including water passed through the water spray; multiple countercurrent spaces and black boxes which are continuously formed alternately on the plate neighbored to the plate; a tube which supplies the air current into the black box by being formed horizontally in the plate; an outflowing hole which is formed in the plate to back flow the air current to the countercurrent spaces in the rear side of the black box. The present invention provides a lot of effects such as having low pressure loss (less than 200mmH2O), having high efficiency of removing harmful material, and enabling to apply in big flow rate, miniaturization, no need to install the demister. |
