EXHAUST GAS TREATMENT PACKAGE SYSTEM

摘要

Provided is an exhaust gas treatment package system which comprises: an inlet unit into which exhaust gas is introduced; a sensor unit for measuring a flow rate of exhaust gas flowing into the inlet unit and concentrations of dust, SO_x and NO_x in the exhaust gas; an exhaust gas treatment package which is coupled to the inlet unit and removes air pollutants in exhaust gas transferred from the inlet unit; and a discharge unit which is coupled to the exhaust gas treatment package and discharges exhaust gas passing through the exhaust gas treatment package. The exhaust gas treatment package includes: a main flow path for connecting the inlet unit and the discharge unit; an electrostatic precipitation module which is connected to the main flow path and has a plurality of electrostatic precipitation units for removing dust in the exhaust gas; a desulfurization module which is connected to the main flow path and has a plurality of desulfurization units for removing SO_x in the exhaust gas; a denitrification module which is connected to the main flow path and has a plurality of denitrification units for removing NO_x in the exhaust gas; and a control unit which controls whether the exhaust gas flows from the main flow path to the electrostatic precipitation units of the electrostatic precipitation module, the desulfurization units of the desulfurization module, and the denitrification units of the denitrification module, depending on the flow rate of exhaust gas and the concentrations of dust, SO_x and NO_x in the exhaust gas, which are measured in the sensor unit.
