Title:
HARMFUL GAS PROCESSING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/204170
Kind Code:
A1
Abstract:
The present invention relates to a harmful-gas-processing system of which the structure is straightforward and which makes it possible to effectively process a harmful gas containing a nitrogen oxide or the like. The present invention provides a harmful-gas-processing system comprising: a processing tank (1) formed so as to have a first gas supply section (5) in the bottom part thereof and formed so as to have a gas discharge port (2) at the top end thereof; a collecting section (10) formed in the bottom part on the inside of the processing tank (1), and comprising a liquid-oxidising-agent collecting section (14) and a liquid-reducing-agent collecting section (15) that are separate from each other; a contact-oxidation section (11) comprising a gas-liquid-contact packing material layer (16) which is disposed above the first gas supply section (5) so as to open to the liquid-oxidising-agent collecting section (14), and comprising an oxidant spray nozzle (23) which is linked to the liquid-oxidising-agent collecting section (14) so as to spray an oxidant onto the gas-liquid-contact packing material layer (16); a contact-reduction section (13) comprising a gas-liquid-contact packing material layer (34) which is disposed above the contact-oxidation section (11) and is disposed so as to allow the passage of a gas to be processed that has gone through the contact-oxidation section (11), and comprising a reducing-agent spray nozzle (36) which is linked to the liquid-reducing-agent collecting section (15) so as to spray a reducing agent onto the gas-liquid-contact packing material layer (34); and a diffusing-and-isolating section (37) disposed between the contact-oxidation section (11) and the contact-reduction section (13), for causing diffusion of the gas to be processed that passes therethrough and for guiding liquid reducing agent, that has fallen from the contact-reduction section (13), through a bypass tube (35) and into the liquid-reducing-agent collecting section (15).
