SNCR+SCR unites denitrification facility

The utility model relates to a SNCR+SCR unites denitrification facility, including reductant preparation and memory system, blending transportation system, pressurization measurement distribution system, injection atomizing system, the out of stock response device of SNCR, SCR reactor, dust removal desulfurizing tower, industrial furnace and exhaust emission system. The out of stock response device of SNCR installs in industrial furnace's furnace, and reductant preparation and memory system, blending transportation system, pressurization measurement distribution system and spray atomizing system and connect gradually the out of stock response device of SNCR, industrial furnace's exhanst gas outlet loop through the SCR reactor and the dust removal desulfurizing tower is connected to the exhaust emission system. The utility model discloses spout the reductant and carry out earlier the SNCR denitration into furnace, the ammonia of escape desorption nox further under the effect of SCR reactor catalyst, full play SNCR method investment province and the high advantage of SCR denitration efficiency have improved denitration efficiency, have reduced flue gas denitration and manufacturing cost.
