Product Description
Hengke PAC powder activated carbon silo and handling system is the integration of our company's proven bin activators, activated and gravimetric feeders. These main system components are integrated with process controls, instrumentation, knife gate valves, and interconnecting piping, all pre-installed within the skirt area beneath a fully engineered storage silo. This integrated system provides precise PAC metering to the final downstream injection system feeding the flue gas ductwork.
Hengke successfully combines testing, equipment design, and system integration capabilities to offer fully integrated PAC powder activated carbon silo and handling systems directly to large environmental/ boiler OEMs who supply complete ACI systems to power plants.

Working Principle
The PAC powder activated carbon silo is a sealed container for storing powdered activated carbon, which is composed of a powdered activated carbon steel silo, a level gauge, a feed pipe, internal and external ladders, manholes, etc. The amount of powder in the steel silo is displayed by the level gauge; when it is low, the PLC electrical control cabinet shows a lack of material status, reminding the water treatment staff to prepare materials in time. The material is fed into the silo through the feed pipe. When the powder in the silo is full during the feeding process, the high position is displayed, prompting the staff that the material in the silo is full. Dust is easy to generate during the feeding process, which will affect the surrounding environment and the operating conditions of employees. It is necessary to turn on the dust removal device during feeding to collect and coalesce the generated dust and return it to the silo.
