Abstract

PURPOSE: An exhaust gas reducing apparatus is provided to stably maintain the temperature of exhaust gas as the flame in a second combustion chamber is rapidly ignited even in the case the flame in a first combustion chamber is extinguished. CONSTITUTION: An exhaust gas reducing apparatus comprises an exhaust pipe(100), first and second combustion units, an injection nozzle(300), first and second igniters, and an air feeder(600). The exhaust pipe delivers exhaust gas to an exhaust gas filter(F). The first combustion unit is installed inside the exhaust pipe, and placed between an engine and the exhaust gas filter. The first combustion chamber comprises a first combustion chamber(211). The injection nozzle is mounted into the first combustion unit, and injects a mixture mixed with air and fuels to the first combustion chamber. One end of the first igniter is placed inside the first combustion chamber, and ignites the mixture injected from the injection nozzle. The second combustion unit comprises a second combustion chamber(521) connected to the first combustion chamber. The air feeder supplies the air to the second combustion chamber. One end of the second igniter is placed inside the second combustion chamber.

Description

technical field [0001] The invention relates to the field of reducing tail gas emissions, in particular to a device for reducing tail gas. Background technique [0002] Generally speaking, trains, ships, and industrial vehicles usually use diesel engines, and cars are increasingly using diesel engines. [0003] With the increasing use of diesel engines, the emissions of suspended particulates such as soot, soluble organic fraction (Soluble Organic Fraction) and nitrogen oxides in the exhaust emitted by diesel engines are also increasing. These emissions are the cause of environmental pollution. The main reason, and therefore its control is getting stronger and stronger. [0004] In order to solve the above-mentioned environmental pollution problems, various schemes that can prevent the exhaust gas produced by diesel vehicles from being discharged into the atmosphere, capture and treat soot, and reduce exhaust emissions are all under study. [0005] Among the exhaust gas re...
