Biochar Aggregate Production via Liquid Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biochar production often results in biochar fines or dust particles with inconsistent particle sizes and low density, leading to distribution and application problems in agriculture and composting, and there is a need for a method to utilize residual biochar dust to create a product with consistent size and physical/chemical properties for uniform distribution and application.
Innovation Solution
A method involving the production of biochar aggregate particles using starch or other binding materials, and additives like microbial products, fertilizers, and vitamins, which includes collecting biochar particles, mixing with binders, and extruding them to create consistent, dust-free biochar solutions that can be easily applied using existing agricultural equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If biochar is produced through pyrolysis, then high carbon content porous material is created, but inconsistent particle sizes and dust particles are generated causing distribution problems
Solution Approach 1:
The patent applies parameter changes by modifying the physical state of biochar from dry particles to liquid suspension form. The biochar is converted into a suspended solution where fine particles are dispersed uniformly in liquid, eliminating dust generation and enabling consistent distribution. This phase change from solid to liquid suspension resolves the particle size consistency issue while eliminating harmful dust particles.
Solution Approach 2:
The patent introduces liquid medium (water or other liquids) as an intermediary carrier for biochar particles. This liquid intermediary suspends the biochar particles, preventing them from settling or creating dust, and enables uniform distribution through existing agricultural irrigation equipment. The liquid mediator transforms the application method from direct solid particle application to liquid suspension delivery.
2Quantity of substance
If biochar fines and dust particles are produced, then more biochar material is created, but low density causes settling and separation problems in application
Solution Approach 1:
The patent utilizes hydraulic principles by suspending biochar particles in liquid medium. The liquid suspension system prevents settling and separation by keeping particles dispersed through the liquid carrier, which can be pumped and distributed through irrigation systems. This hydraulic approach maintains mixing uniformity while utilizing all biochar material including fines and dust particles.
Solution Approach 2:
The patent changes the density parameter by incorporating low-density biochar fines and dust particles into a liquid suspension matrix. This parameter change transforms the application from handling dry particles to distributing liquid suspension, where the liquid medium prevents settling and maintains uniform composition throughout the application process.
3Adaptability or versatility
If standard agricultural equipment is used for biochar application, then existing infrastructure can be utilized, but equipment is not equipped to handle dust and fine particles
Solution Approach 1:
The patent inverts the conventional approach by not applying dry biochar particles directly but instead applying liquid suspension containing biochar. This inversion transforms the problem from adapting equipment to handle particles to using existing liquid application equipment in reverse for its intended purpose, eliminating dust and clogging issues while utilizing standard irrigation infrastructure.
