Gas scrubbing method using electric energy and fossil fuel and gas scrubber thereof

摘要

The present invention relates to a burning type gas scrubbing method using an electrical energy and a fossil energy at the same time, and a gas scrubber implementing the method. The gas scrubber has a burning chamber, the burning chamber comprising an inner casing defining a burning room; at least a gas inlet for introducing the waste gas into the burning room; an air inlet for introducing air into the burning room; and an electrical heater disposed on an outer circumference of the burning room and connected to a power source through a power supply line. The burning room comprises an ignition fuel port for introducing an ignition fuel into the burning chamber when the temperature of the burning room rises above a predetermined temperature, an ignition sensor for a flame generated by injecting the ignition fuel, and a main fuel port for supplying a large amount of fuel when the ignition sensor senses an ignition flame. According to the gas scrubbing method and the gas scrubber of the present invention, the electrical energy and the fossil energy are used together, thereby enhancing the energy efficiency and the gas scrubbing efficiency at the same and decreasing the emission of CO₂ gas.
