Segmented Nozzle for Faster CO2 Dissolution in Carbonation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carbonation systems, especially smaller residential systems, are inefficient in dissolving carbon dioxide in water, requiring large amounts of CO2 and significant time due to a significant portion of CO2 failing to dissolve.
Innovation Solution
A nozzle with a metal tip having specific dimensions, including a first portion with a substantially constant diameter and length, and a second portion with a diameter that increases, is used to emit carbon dioxide bubbles with a smaller average diameter, increasing the surface area and dissolution rate in water.

Engineering Contradiction Analysis
1Productivity
If conventional nozzles are used in carbonation systems, then the system is simpler and easier to manufacture, but the CO2 dissolution efficiency is low requiring large amounts of CO2 and significant time
Solution Approach 1:
The nozzle interior surface is segmented into multiple zones with different diameters (first portion with constant diameter, second portion with increasing diameter). This segmentation creates specific flow patterns that enhance CO2 dissolution efficiency, allowing faster carbonation with less CO2 consumption.
Solution Approach 2:
Different portions of the nozzle interior surface have different geometric properties (constant diameter vs. increasing diameter). This local quality variation optimizes gas-liquid interaction at different locations, improving overall dissolution efficiency while reducing total CO2 requirements.
2Productivity
If conventional nozzles are used, then manufacturing is simpler, but the carbonation process takes significant time
Solution Approach 1:
The segmented nozzle structure with distinct first and second portions creates optimized flow dynamics that accelerate CO2 dissolution. The specific diameter variations in each segment promote efficient gas-liquid contact, significantly reducing the time required for carbonation.
Solution Approach 2:
The nozzle geometry parameters (diameter variations along the interior surface) are specifically designed to optimize dissolution kinetics. By changing the geometric parameters of the nozzle interior surface, the carbonation speed is enhanced while minimizing time loss.
3Productivity
If a nozzle with precise dimensional specifications is manufactured, then dissolution efficiency improves, but manufacturing precision requirements increase
Solution Approach 1:
The nozzle is divided into two functional segments with different geometric characteristics. This segmentation allows each portion to be optimized for its specific function while maintaining overall manufacturability. The first portion's constant diameter and the second portion's increasing diameter can be achieved through standard manufacturing processes with reasonable tolerances.
Solution Approach 2:
Each portion of the nozzle interior surface has locally optimized geometry tailored to its specific function in the dissolution process. This local quality approach allows manufacturing precision to be focused where most critical, while other areas have more flexible tolerance requirements, balancing efficiency with manufacturability.

AI summary
Described herein is an example of a nozzle that can include a metal tip having a first end and a second end. The metal tip can also define a conduit extending from the first end towards the second end. The conduit can include a first portion and a second portion. The first portion of the conduit is defined by at least one first interior surface of the metal tip extending from the first end. The first portion of the conduit can exhibit a substantially constant diameter and a first length. The second portion of the conduit is defined by at least one second interior surface of the metal tip extending from the first portion for a second length. The second portion can exhibit a diameter that generally increases with distance from the first portion and can exhibit a generally truncated conical shape exhibiting an open angle.
