Abstract

The present disclosure provides a gas treating apparatus comprising a reaction chamber configured to process a gas supplied from an outside by a plasma, the processed gas containing a nitrogen oxide,and a nitrogen oxide reduction apparatus connected to the reaction chamber. The nitrogen oxide reduction apparatus includes a cooling unit configured to cool the processed gas to a temperature lower than a nitrogen oxide generation temperature.

Description

technical field [0001] The present invention relates to a nitrogen oxide reduction device and a gas treatment device comprising the nitrogen oxide reduction device. Background technique [0002] In the case of decomposing harmful gas by using a plasma generating device, the harmful gas is treated at a high temperature, and this may generate nitrogen oxides. In particular, at a high temperature of about 800° C. or higher, the amount of thermal NOx (nitrogen oxides) generated by reaction with an oxygen-containing reaction gas increases. Nitrogen oxides cause acid rain and photochemical smog, and are considered one of the major air pollutants. Therefore, a technology capable of reducing nitrogen oxides is required. [0003] Conventionally, catalytic units or dilution units are used for the treatment of nitrogen oxides. However, these devices are not cost-effective. As another solution, the use of oxygen-containing materials has been avoided in order to prevent the generatio...
