A dust removal, desulfurization and denitrification process of dust removal, desulfurization and denitrification integrated equipment comprises the following steps:
after the dust-containing gas enters the contraction pipe 13 from the gas inlet pipe 8, the flow velocity is gradually increased, the gas flow velocity reaches the maximum value in the throat pipe 14, and the relative velocity between the gas and the liquid reaches the maximum value. The desulfurization and denitrification mixed liquid sprayed out of the spray pipe I6 in the contraction pipe 13 is atomized under the impact of high-speed airflow. The dust gas is fully contacted with the desulfurization and denitrification mixed liquid and reaches saturation, and a gas film attached to the surface of dust particles is broken, so that the dust particles are wetted and are violently condensed. In the expansion tube 16, the velocity of the air flow decreases and the pressure rises again, and the condensation with dust particles as condensation nuclei is completed and the dust particles are condensed into larger dust-containing water droplets.
