The energy and power generation industry (coal-fired, waste-to-energy and biomass power plants), steel, cement, chemical, construction materials industry as well as food processing industry and applications in many other related industries, where in bulk solid material movement and for Conveying requirement is to be performed, PHS with Pneumatic force is employed. For bulk Loading and Un-Loading of solid Materials in Railway wagon, bulk transport containers etc, PHS is very well suited. SaveEco Energy is pioneer to the solution of Critical Pneumatic Conveying Systems.
The conveying technology basically distinguishes between two different processes. The decision is taken on basis of respective application, based on your needs and expectations.
Dense Phase Conveying with unique dense phase pressure vessel system.
Dilute Phase Conveying (Pressure / Vacuum) with rotary valve feeder, butterfly valve or an injector.
Either system may be the system of choice and have its benefits, often some combination of two technologies is needed to arrive at an optional solution conveying technology basically.
Comparison Dense Phase / Dilute Phase
|Designation||Unit||Dense phase conveying||Dilute phase conveying|
|Conveying pressure||bar ü||high||low|
|Quantity of air / air consumption||Nm3/h||low||high|
|Loading (bulk material/air)||kg/kg||High||low|
|Plant / product wear||low||high|
|Conveying distances||m||up to 2000||up to 250
|Continuous conveying||Possible With additional equipment||yes|
|Discontinuous conveying (batch operation)||yes||yes, possible
|Depending on the bulk material||exclusively||limited|
Conveying with air slides
Air slides involve another tried-and tested pneumatic conveyor system that is normally used for large mass flows.
The bulk solids are fluidised and thus made free-flowing, and gravity does the rest. That means that an appropriate slope must in each case exist between the location of the product and its intended destination.
Dense Phase Conveying
Dense phase conveying systems are fitted with:
As a standard, the pressure vessel operates at pressure up to 6 bar (g), conveying distance of more than 1000 m or conveying rate of up to 300 t/hr.
Dense Phase Pneumatic Conveying System
Dilute Phase Conveying
This technology is basically used for continuous transportation with low conveying rates over short distances. Dilute phase conveying system fitted with
Based on material properties and characteristic the type of system is selected.
