APPARATUS FOR INTRODUCING A LIQUID AGENT TO REDUCE HARMFUL OBJECT IN EXHAUST GAS

摘要

An apparatus for injecting a liquid sample for reduction of harmful materials in exhaust gas is provided to lower the flow rate control decomposition capacity by including a liquid sample injection unit using a piezoelectric method. An apparatus for injecting a liquid sample for reduction of harmful materials in exhaust gas includes an air supply section(100), a sample supply section(200), and a power source supply section(300). The apparatus includes upper and lower electrodes connected to the power source supply section, a piezoelectric device located between the upper electrode and the lower electrode and deformed as a power source is supplied to the upper and lower electrodes, and a chamber for discharging the sample supplied from the sample supply section through a nozzle. The apparatus includes a unit for rotating the air supplied from the air supply section.
