How is long-distance pipeline transportation of dry lime carried out? ? Is there a way? If it is transported as a lime emulsion, what methods can be used to prevent clogging? ?
Dry powder is mixed using a bin pump, while slurry is mixed using a hydraulic pump
If dry lime is in powder form, it can be transported by air. It is prepared as a lime slurry for transportation, and care must be taken to clean out the residual medium in the pipes when shutting down.
Dry lime can be transported by pipeline over short distances, but not over long distances. Lime slurry can be transported over medium to long distances; by properly adjusting factors such as the water-cement ratio, flow rate, and pipe diameter, blockages generally do not occur.
Dry powder can be transported by pulse pneumatic conveying, or by screw conveyors or belt conveyors. The suspended material can be transported by slurry pumps or screw pumps.
Even just the material supply is intermittent; once the medication is stopped, the long-distance pipelines will be filled with lime slurry, which can easily cause blockages
Can it be transported over a distance of around 100 meters? ? What volume of air and what ratio of ash are required? What level of air pressure is needed, and is positive pressure or negative pressure better?
What kilopressure is required for the hydraulic pump? ?
Is it better to use positive pressure or negative pressure for pneumatic conveying? What pressure is required? ?
If pulse conveying is used, it is of course positive pressure conveying, and the pressure depends on the conveying height and distance.
