Open Source Fluidized Bed Technology Demonstrator

Basics

• Fluidised Solids have many uses for chemical reactants, Gas Scrubbers, and combustion/gasification
• These are complex devices, and thus a sort of development workbench would be of use
• This is such a device

Existing Open Source Designs

• This PVC Pipe and Plastic Container Based Design the air in this was quite coarse perhaps impacting fluidity
• A Device using a barrel and a cloth covered pipe air distributor

Minimum Viable Product

• Various tube options such as
  • Small PVC Pipe
  • Acrylic/Clear Pipe for Observation
  • Steel Pipe for Large and/or durable designs
  • Fused Quarts Tube for Observation of Heat Involving Experiments
• Should work with a standard shop compressor
• Should be fully fluidized, and have little bubbles/inconsistencies in the fluidization

Basic Design

Base

• Most likely some sort of sheet metal or other sheet
• A pipe holding support, direct cap/pipe weld or some sort of similar device

Tube

• 1 Inch PVC Pipe
• 1 Inch Acrylic Pipe
• 1 Inch Steel Pipe
• Fuzed Quartz Pipe
• 10 Inch Steel Pipe

Air Injection Mechanism

• Arduino Controlled Valve
• Some sort of Air Diffuser perhaps aquarium/wastewater treatment Off the shelf, would graphite work?
• All of this is fitted to either an end cap, or the baseplate
• Perhaps make the diffuser a module to allow for swapping of various designs
• [FLUIDIZING PLATE https://www.alibaba.com/showroom/fluidizing-plate.html] is the word for the device used for large scale devices such as powder coating

Fluid Injection Module

• Alternate Use with liquids
• Can act as a Sand Filter with more surface area for microbial growth, or for chemical reactions
• Perhaps just plates/piping with holes

BOM

PVC Pipe

• Possible Air Diffuser 8 inch diameter (inner or outer?)
• Look into sheet raw material
• Cut into shape, glue into pipe (or use some sort of cupling with a lip/reduction in diameter) the put an air valve below it
• Use aggregate from local hardware store as media (look for finest possible such as sand)

Bin

• 1x plastic Bin (or paint can)
• bubble releasing tube from local store (big box or pet/aquarium store most likely
• Adapter to air compressor
• Valve of some sort

Diffuser

• This one should fit the base of a 1 gal paint can with room on the edges for sealant
