In summary, the device for drying carbon black that the present invention is provided, wet carbon black is transported to blade by feeding screw and dried
Dry machine, dispels flash distillation by the superheated steam discharged on the exhaust outlet of material toggling part before the extruding by blade and loses a part
Moisture, makes carbon black loose, improves the mobility of carbon black, while reducing residence time of the wet carbon black in drying chain-drive section, keeps away
Exempt from carbon black caking, extrude and destroy carbon black structure, the drying efficiency for improving carbon black also improves carbon black products quality；Material toggling part with
Steel pipe form is present, and exhaust ports design is set into along the parallel axis direction with steel pipe, and the length of exhaust outlet is more than or equal to spiral shell
The feed opening of precession glassware parallel to steel pipe axis length, while the feed opening of material toggling part and feeding screw is vertically arranged,
So that exhaust outlet discharge superheated steam it is vertical with the wet carbon black discharged from feed opening, it is ensured that wet carbon black and superheated steam it is abundant
Contact, the contact area of wet carbon black and superheated steam is maximum, the expansion drying efficiency high of wet carbon black, and dispels degree under this state
It is maximum；Material toggling part, blade dryer, the control of the input of air heat exchanger and the steam in hot air heat exchanger pass through corresponding pipeline
The valve of upper setting is controlled, and temperature control is not being destroyed the temperature of carbon black structure；Carbon black after expansion drying passes through
The contact drying for the saturated vapor being passed through in chuck on blade and housing, drying effect is good；Evaporated after blade drier
The hot-air that the moisture gone out is produced after being heated through air heat exchanger is carried over offgas outlet, into later stage tail gas treatment stage,
Reduce the pollution to environment；Tail gas is added before sack cleaner is entered by hot air heat exchanger to outside cold air
Heat, supplements a part of hot-air, by exhaust temperature control on dew point, it is to avoid sack cleaner paste bag；Unloaded by star-like
Material valve is realized carries out discharging to the carbon black collected in cyclone dust collectors and sack cleaner, simple to operate, it is easy to accomplish, it is easy to rotation
The collection of carbon black in wind deduster and sack cleaner；Blade dryer, hot air heat exchanger and air heat exchanger are after heat exchange
The condensed water of generation is all back in condensate draining by connected condensing water conduit respectively, and the condensed water of whole system is returned
Reducing-and-cooling plant is used, as the moisturizing of reducing-and-cooling plant, water resource is recycled, accomplishes that the energy makes full use of.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
