  1. BLOWER TECHNOLOGY

  2. TYPES OF BLOWERS • FAN -Hight capacity of air -Low pressure -Max. ∆p=100mbar • SIDE CHANEL -Hight capacity of air -Low pressure -Max. ∆p=300mbar

  3. TYPES OF BLOWERS • Hight capacity of air • Medium pressure • Max.∆p=1000mbar • BLOWER ROOTS PEDRO GIL manufactures roots type positive displacement blowers for several industrial applications such as pneumatic conveying of bulk materials (food, cement, chemical material etc.), waste water treatment, vacuum applcations, gas moving processes and fish farming. Roots type blowers can provide high volumes of air up to 1000 mBar of pressure and 500 mBar of vacuum depending on operating conditions. • COMPRESSOR • Medium capacity of air • Hight pressure • Max.∆p= >10bar

MAIN APLICATIONS OF BLOWERS • WASTE WATER TREATMENT • PNEUMATIC HANDLING CONVEYING AND DOSING SYSTEMS • FLUIDIFICATION • LOW PRESSURE AIR CONVEYS MATERIAL • AERATION WITH LOW PRESSURE AIR • PRESSURE MATERIAL CONVEYING • LOW PRESSURE AIR EXPEDITES BULK CONVEYING • LOW PRESSURE AND VACUUM CONVEYING • LOW PRESSURE AIR SUPPORT COMBUSTION • CENTRALY LOCATED VACUUM SYSTEM MAKES CLEANING EASY • VACUUM PACKAGING • MIXING SEDIMENT • PUNCH COLLECTOR • SEWING MACHINE • VACUUM TRANSFER • LOW PRESSURE AIR AGITATES CHEMICAL SOLUTIONS • VACUUM CONVEYS BULK

  13. GROUP WITHOUT CONECTION TO THE INSTALLATION 1.-Some fences filter the solids of biggest size 2-3.-the water will pass for two types of machines, the "grit tanks", which will eliminate the sands and heavy solids, and the "degreasers", that will erase any type of greasy, and floating existing in the water 4.-The water passes to some deposits where the particles in suspension settle deep down. 5.-The biological treatment has it as goal to eliminate the fertility pollution of the waste waters.This process is developed in tanks aired where a mud activated with microorganisms that assimilate the biodegradable organic matter is formed 6.-The secondary settling consists of a secondary settling whose mission is to separate the mud activated of the water.

  15. AERATION WITH LOW PRESSURE AIR Infonation of the customer: FLOW and PRESSURE h=∆p -Flow depend of the volum of watwer. -Pressure is ± hight of the tank. h Biological treatment O2 expensive AIR 20% O2 Low pressure air is used in sewage treatment aeration tanks.The air is used to support the bacteria which in turn break down the organic matter

  16. DIFERENTS APLICATIONS TO PNEUMATIC HANDLING CONVEYING AND DOSING SYSTEMS

  17. INDUSTRIES SERVED / BULK MATERIALS CONVEYED • Agriculture: Wheat, flour, semolina, barley, oat, rye, bran, chaff, feed, seed, corn, chickpea, bean, lentil, pea, soy bean, sesame, rice, pice flour, dried fruit, hazelnut, peanut, almond, sunflower seed, cotton seed, grain cereals, chestnut are some of the bulk materials that can be conveyed with pneumatic transportation systems. • Food Industry: Grains and powders like coffee grain, coffe powder, sugar, salt and spice can be conveyed. Stainless steel equipment (rotary valves, piping, silo) is used in food conveying. • Other Industrial Materials: Cement, mining minerals, petrochemical materials, pharmaceuticals, medical powders, calcite, pvc, ash, glass powder, marble powder, plastic pellets, sawdust are some of the bulk solids that can be conveyed

  18. MATERIALS FOR PNEUMATIC TRANSPORT The most common materials for the pneumatic transport are any material powdered or granulated as: • Sugar • Coffee • Coal • Calcium carbonate • Cement • Flour • PVC • Wheat

  19. In conveying of material we have 2 phases: • Dense phase The dense phase it is used in sectors as the cement or detergents. This technology uses compressed air to pressures that vary bar from 2 to 5 and is suitable for every type of materials and ideal for abrasive products, where the low speed of transport prevents wears in pipings, elbows and other elements.Its Their main characteristics are the reached distances, up to 2.000 m, and the productions up to 500 t/hr. Besides, the piping is of smaller diameter in relation to the diluted phase, guarantee that losses of air or product during the transport are not produced, are of low air consumption and of low operative costs.Likewise, the densificación of the product in the piping and the low speed of transport (among 2 to 12 m/sec) allows a soft treatment of the product, preventing the breaking of the particles • Diluted phase The systems of pneumatic conveyors of phase diluted move material to granel suspended in a draught that is introduced by a blower of positive pressure before the points of entry of materials, or by a vacuum pump that eliminates the air of the system after the points of offloading of materials. The material is separated airborne from transport in the point of use, and it unloads afterwards in sets by throttle flap valves either of paper cutter, or in a continuous way by rotable flap valves of inner tube.

  20. PRESSURE MATERIAL CONVEYING Infonation of the customer: FLOW and PRESSURE ATMOSPHERE Low presure air carries the material from the hopper into the bin. • Pressure depend of the Ø of pipe, Qa of material to conveying and leng of pipe • Flow depend of the speed that the product need to be conveyed

  21. LOW PRESSURE AIR EXPEDITES BULK CONVEYING Infonation of the customer: FLOW and PRESSURE Qa A blower can expedite gravity in bulk material conveying systems. P2

  22. LOW PRESSURE AND VACUUM CONVEYING VACUUM A vacuum pump pulls the material from the hopper into the bin.

  23. MIXER FILLING, MIXER UNLOADING, MIX PREPARING, DOSING Inner tube clean Door of access Air drain clean Venturi tube Injector tube Filter bag Deposit of compressed air Air inlet dirty Dosing different granular or powdered materials from silos and filling a mixer or blender Inner tube dirty Offloading of dust

  24. MIXER FILLING, MIXER UNLOADING, MIX PREPARING, DOSING Unloading a mixer and loading a bag

  25. SILO LOADING Conveying From a Machine to Silo with pneumatic conveying system Silo filling from ground by grain vac system

  26. WEIGHING Vacuuming bulk solids from ground, weighing and bag filling

  27. LOW PRESSURE AIR CONVEYS MATERIAL A blower supplying low pressure air conveys insulating material to the job site.

  28. TRUCK LOADING, TRUCK UNLOADING Truck unloading by mobile pneumatic conveyor 

  29. TRUCK LOADING, TRUCK UNLOADING Silo discharging and truck loading of grain with pneumatic conveying

  30. FLUIDIFICATION The basic beginning of the process of fluidification consists in using pressure of air to hold in movement the material that it|he finds in the interior of the silo so that it does not pile up in the inferior part.

  31. LOW PRESSURE AIR SUPPORT COMBUSTION A gas pump and blower are used in combination air mixes proportionately with the gas to provide a combustible mixture to the burner.

  32. CENTRALY LOCATED VACUUM SYSTEM MAKES CLEANING EASY The easily accessible sockets of vacuum do the cleaning of the buildings easy and effective . Central vacuum system ideal for cement plants, plants where aspiration is carried out for vacuum.

  33. MIXING SEDIMENT Agitating material by air provides for more complete mixing.
