Description

Technical Field

[0001] The utility model relates to the technical field of carbon black, in particular to an exhaust gas collection device for producing carbon black. Background Art

[0002] Carbon black refers to a black powdery substance formed by incomplete combustion or pyrolysis of gas phase under strictly controlled process conditions. Carbon black exhaust gas refers to the gas after separating carbon black from carbon black flue gas, which is not allowed to be directly discharged into the atmosphere and can also be reused as secondary energy, such as used as boiler fuel or power generation, etc.

[0003] An existing exhaust gas collection device for carbon black production (publication number: CN208680129U) has at least the following drawbacks: when in use, the sealing bag body of this device is made of flexible material, which can shrink like a food bag as the internal air decreases when not collecting gas, and can stretch when collecting gas. However, the exhaust gas is doped with dust impurities and cannot be effectively treated, which affects the collection effect and is not conducive to further treatment by staff.
