Gas storage device 220 is used to store nitrogen.Second nitrogen storage device 220 is connected to the second reacting furnace 120, and the second nitrogen
The inside of storage device 220 is communicated in inside the second reacting furnace 120, so that the second nitrogen storage device 220 can be anti-to second
Answer and be passed through nitrogen inside stove 120, to supplement the nitrogen needed for 120 internal-response of the second reacting furnace, ensure in the second reacting furnace 120
The nitrogen gas concn in portion is in the degree that can carry out normal reaction, ensures that the reaction inside the second reacting furnace 120 can be carried out stably.
It should be appreciated that in other embodiments, the setting of the second nitrogen storage device 220 can also be cancelled, pooling zone 420 can be passed through
Superfluous nitrogen directly feed the required nitrogen in the inside of the second reacting furnace 120.
Further, atmosphere furnace tail gas recycling device 10 further includes air inlet pipe 221, the second nitrogen storage device 220
It is communicated in by air inlet pipe 221 inside the second reacting furnace 120, so that the second nitrogen storage device 220 can pass through air inlet pipe 221
Nitrogen is delivered to inside the second reacting furnace 120.Wherein, the communicating pipe 300 of pooling zone 420 is connected to close to the second reacting furnace
120 one end is connected to air inlet pipe 221, and is connected to the communicating pipe 300 of pooling zone 420 close to the end of the second reacting furnace 120
Portion is set towards the second reacting furnace 120.The second nitrogen storage device 220 can be caused to be reacted by air inlet pipe 221 to second
During 120 inside air inlet of stove, by the swiftly flowing nitrogen that the second nitrogen storage device 220 produces in communicating pipe 300 close to the
Two reacting furnaces, 120 one end forms Negative Pressure Difference, and the air-flow inside communicating pipe 300 can be promoted to follow what 221 high speed of air inlet pipe flowed
Nitrogen flows into inside the second reacting furnace 120 together, further avoids the tail gas inside the second reacting furnace 120 from passing through communicating pipe 300
Being back to pooling zone 420 influences the efficiency of vent gas treatment.It should be appreciated that the communicating pipe 300 for being communicated in pooling zone 420 can also be straight
