Powder activated carbon cast device System configuration 1, loading system: the main function of the feeding system is to transfer activated carbon in the warehouse or tank truck to the system of the silo storage. Generally according to the situation is divided into two kinds: bagging loading system, tank loading system;
2,storage system: storage system for the storage of powder. It is necessary to ensure that the powder casting process has the ability to feed continuously, to ensure the excellent physical properties of the powder, and to consider the drying, dust removal, arch breaking and safety problems in the powder storage process;
3,powder delivery system: powder transmission through a quantitative spiral of activated carbon powder from the silo to the solute system. The selection of the whole system needs to choose the right conveyor and the right conveyor combination according to the design and construction process. Also consider the powder in the delivery process will encounter clogging problems, how to prevent clogging, whether it is necessary to adjust the amount of powder activated carbon by adjusting the variable frequency motor, it is recommended to use a shaftless spiral conveyor;
4,the dissolution system: after calculation, a certain amount of water and through the delivery system quantitatively added powder activated carbon, in the container after stirring, mixing, with the required concentration of activated carbon powder, generally5%-10%. The dissolution system is divided into three-chamber and two-cavity;
5,liquid feeding system: through the power system and pipeline system to the matching solution cast to the filling point. Power systems generally use screw pumps, metering pumps, pipeline systems including lines and a variety of valve flow meters;
6,control system: for the entire system of automated control, divided into semi-automatic control and fully automatic control. How it works: The uniformity of the wet process is better, the main factor is that carbon powder and water in the mixing tank can be mixed very uniform slurry, so after the metering pump is delivered to the filling point (water collection line), the dispersion uniformity of carbon powder in the pipeline is better. Wet process using the preparation of activated carbon slurry, by the measurement pump quantitative delivery to the filling point of the way, activated carbon slurry using the metering pump injection, so the amount of activated carbon slurry can be controlled very much. Cast plus: The drop-and-add pump uses different types of metering pumps, screw pumps or centrifugal pumps according to the needs of different customers. The powder activated carbon slurry mass score is generally 5%to10%. However, 5% more wet casts are used,which allows the carbon slurry to spread quickly and mix well with the water body, while avoiding the easy clogging of the cast pipes and other mechanical failures. Features of the product The main components are imported products to increase the stability and reliability of the system The powdering material is uniform and stable. Pipeline flushing and line dilution effectively alleviate the blockage of the cast system, the new pipe flushing system. The whole system operates fully automatically, which can reduce human resources Full closure operation can avoid causing environmental pollution
