Nitrification reactor

摘要

Problem to be solved: to provide a batch type nitriding reactor in which the nitridation reaction is completed in a short time, and the deterioration of the heater and the heat insulating material by the auxiliary gas is suppressed.Nitrification reactorHaving an insulating casing 1In the insulation casingA reaction chamber 5 surrounded by a shield wallA heater 3 disposed outside is disposed.Within reaction chamberA tray 19 containing a reaction raw material is placed in multiple stages.Each trayThe exhaust pipe penetrating tube and the side wall have notches.From the bottom of reaction chamberPenetrating the shield wallA gas exhaust pipe 17 extends through the exhaust pipe penetrating tube.Nitrogen gas is supplied to the gap s between the peripheral portion of each tray 19 and shield wallThe nitriding reaction is conducted by contacting nitrogen gas into the reaction material contained in each trayUnreacted nitrogen and by-gasA nitrification reactor having a structure discharged from an exhaust pipe 17 through the exhaust pipe penetrating tube of each tray 19.Diagram
