Method for removing gaseous impurities from combustion gases and equipment for removing gaseous impurities from combustion gases

摘要

the subject of the invention is the removal of gaseous pollutants, especially acidic organic pollutants, and heavy metals from exhaust gases, in particular from waste incineration plants and device for implementation of this method. the way is that the exhaust gas (1) is all to the reactor from the bottom through the input (2), usually at 12u00f740 m / s to the reactor (5).angle of cone separation reactor (5) from 12u00f716u00b0 enables uniform rozpu0142yw exhaust in the mountain where the speed reducing reagent and increase concentration within the vertical axis of the reactor (5). the increased concentration migrates along vertical axis camera depending on the load and the changing speed of exhaust in the gorge.absorbable (6, 7) are supplied with recyrkulowanymi with odpylacza (8) reaction products within the diffuser. the increased concentration zraszana water spray is rozpylanu0105 high pressure nozzles (3), oczyszczanymi periodically with narostu00f3w by devices (4). leaving the reactor is separated in a dry aerosol odpylaczach (8), preferably by means of a bag filter.the cleaned exhaust gases (9) are directed to the chimney (10), and separated from the aerosol products aftertreatment (11) partially back to the reactor (5), with the remainder (12) outside the installation.device for removing gaseous pollutants from exhaust gases, is a vertical reactor (5), whose upper part takes the form of a diffuser cone dilated within a range 12u00f716u00b0, placed in its lower part of the inlet (2) the contaminated gas.conical part of the reactor (5) is coupled with odpylaczem (8) connected with the chimney installation piping (10) draining the purified exhaust gas.
