Effluent processing apparatus for a vehicle air brake charging system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle air brake charging systems suffer from the deposition of oil onto roadways due to the purging of air containing oil droplets from the air dryer's purge valve, which is not effectively cleaned before release.
Innovation Solution
An effluent processing apparatus with a quadric surface defining an effluent flow chamber that extracts contaminants from the effluent stream as it flows from the inlet port to the outlet port, utilizing a vortex flow and filtration media to separate and hold oil and water droplets, thereby preventing their deposition on roadways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air dryer purges air containing oil droplets from the purge valve, then the desiccant material is regenerated and water is removed, but oil droplets are deposited onto roadways causing environmental pollution
Solution Approach 1:
The patent extracts and removes oil droplets from the effluent stream before discharge. The effluent processing apparatus separates oil contaminants from the air stream using centrifugal force and filtration, allowing only cleaned air to be expelled from the purge valve, thereby preventing oil deposition on roadways while maintaining desiccant regeneration functionality
Solution Approach 2:
The patent introduces an effluent processing apparatus as an intermediary component between the air dryer purge valve and the atmosphere. This intermediary device processes the effluent stream by removing oil droplets through centrifugal separation and filtration media, allowing the system to achieve both desiccant regeneration and environmental protection
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 apparatus effectively removes contaminants from the effluent stream, resulting in cleaner air being expelled and minimizing oil deposition on roadways, while maintaining minimal back pressure on the purge valve and allowing for efficient contaminant extraction and filtration.
Implementation Method 1
The effluent processing apparatus further comprises means for directing an effluent stream from the purge valve into a vortex flow to extract contaminants from the effluent stream
Implementation Method 2
The air then moves through the desiccant material which removes most of the water vapor
Implementation Method 3
Most of the oil droplets are removed by the oil separator as the air passes into the air dryer

AI summary
An effluent processing apparatus is provided for a vehicle air brake charging system. The effluent processing apparatus has an inlet port through which effluent from a purge valve of an air dryer can be received and an outlet port. The effluent processing apparatus further has a quadric surface defining an effluent flow chamber that is connected in fluid communication between the inlet port and the outlet port. The quadric surface is provided for extracting contaminants from an effluent stream as the effluent stream flows from the inlet port along the quadric surface to the outlet port.
