Pipe Skid Nozzle for Targeted Root Treatment Above Fluid Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for treating clogged pipes with vegetation or roots are inefficient in applying chemical agents, often requiring excessive amounts of chemicals and wasting agents due to fluid flow interference.
Innovation Solution
A skid assembly with a delivery nozzle and dispensing tip that moves longitudinally within the pipe, using high-pressure water to position the skid and then applying a chemical agent through a controlled orifice to deliver a precise stream of chemical agent upwardly away from the fluid surface, minimizing chemical usage and ensuring targeted treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional chemical treatment systems are used to treat clogged pipes, then vegetation and roots can be killed, but excessive amounts of chemical agents are required and chemicals are wasted due to fluid flow interference
Solution Approach 1:
The dispensing tip is configured to deliver chemical agent locally and precisely to the specific area where vegetation or roots are present, rather than applying chemical throughout the entire pipe. The tip delivers a controlled stream that targets only the affected zones, reducing overall chemical consumption while maintaining treatment effectiveness.
Solution Approach 2:
The system replaces conventional mechanical application methods with a controlled fluid delivery mechanism. The dispensing tip uses fluid dynamics to create a controlled stream of chemical agent that resists dispersion by pipe fluid flow, substituting uncontrolled mechanical spraying with precision fluid delivery.
2Reliability
If chemical agent is applied throughout the pipe, then vegetation can be treated, but fluid flow interferes with chemical application causing waste
Solution Approach 1:
The dispensing tip is designed to dynamically adapt to the fluid flow conditions within the pipe. The tip configuration allows it to maintain a controlled chemical stream despite the surrounding fluid flow, creating a dynamic balance between chemical delivery and fluid movement that ensures reliable treatment while minimizing loss.
Solution Approach 2:
The controlled stream of chemical agent acts as an intermediary between the chemical supply and the vegetation. This controlled stream configuration allows the chemical to reach the target effectively while the stream structure itself protects against dispersion and waste from fluid flow interference.
3Measurement precision
If conventional spraying methods are used, then chemical can reach vegetation, but application precision is poor and chemicals are wasted
Solution Approach 1:
The dispensing tip delivers chemical agent with high spatial precision, targeting only the specific locations where vegetation or roots are present. This localized application approach dramatically improves measurement precision of chemical placement while reducing the total quantity of chemical required compared to conventional broad-area spraying.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for precise and efficient application of chemical agents, using significantly less chemical than previous methods, effectively treating affected areas within pipes while minimizing the introduction of harmful chemicals into the fluid flow.
Implementation Method 1
A pressurized fluid can be applied to a delivery nozzle carried by the skid to cause the skid to move to position the skid in a desired longitudinal location within the pipe
Implementation Method 2
The dispensing tip can be limited from delivering the chemical agent downwardly toward the bottom of the skid assembly such that the dispensing tip delivers the controlled stream of chemical agent upwardly away from the bottom surface of the pipe and upwardly away from the fluid surface

AI summary
A system for applying a chemical agent within a pipe includes a skid assembly, moveable longitudinally within the pipe. The skid assembly has a bottom positionable on a bottom, internal portion of the pipe. A delivery nozzle is carried by the skid assembly and is coupleable to a chemical agent supply. A dispensing tip delivers a controlled stream of chemical agent within the pipe toward an internal surface of the pipe. The tip is held at or above a surface of fluid carried by the pipe while at least a portion of the skid assembly is positioned below the fluid surface. The dispensing tip is limited from delivering the chemical agent downwardly toward the bottom of the skid assembly such that the dispensing tip delivers the controlled stream of chemical agent upwardly away from the bottom surface of the pipe and upwardly away from the fluid surface.
