Title:
METHOD FOR TREATING NITRIC OXIDE IN EXHAUST GAS
Document Type and Number:
WIPO Patent Application WO/2017/193671
Kind Code:
A1
Abstract:
A method for treating nitric oxide in exhaust gas, said method comprising the following steps: obtaining an exhaust pressure value at an automobile engine exhaust pipe outlet (S101); when the exhaust pressure value reaches a preset value, monitoring automobile exhaust gas in real time via infrared detection means, and generating a corresponding electric signal according to an absorbed infrared wavelength range and an absorption degree (S102); sequentially performing filtering and amplification processing on the electric signal, obtaining the types of harmful gases in the electric signal after the amplification processing, and identifying the various harmful gases according to the types of the harmful gases (S103); according to the identification, determining whether the harmful gases in the exhaust gas include nitric oxide (S104); if yes, generating a catalytic reaction command, and via the catalytic reaction command, discharging the exhaust gas to a photocatalytic reactor for nitric oxide treatment (S105). The method for treating nitric oxide in exhaust gas effectively treats nitric oxide in automobile exhaust gas in a timely manner, and reduces environmental pollution and bodily harm.
