Toxic Waste Container Venting With Forced Air Gas Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste containers for toxic waste do not adequately prevent the release of toxic gases into the environment during collection and storage while maintaining ease of use.
Innovation Solution
A waste container design featuring an annular chamber with air inlets at the base, a hollow column with a forced air circulation device, and a fluidic link for airflow communication, allowing toxic gases to be suctioned vertically without compromising the opening mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a waste container is designed with a closed structure to prevent toxic gas release, then environmental protection is improved, but ease of operation for waste collection deteriorates
Solution Approach 1:
The container is divided into two functional zones: a closed lower body for secure waste storage and a movable upper hood for easy access. The hood can be lifted to expose the filling opening while the lower body remains sealed, allowing operators to collect waste without compromising the sealed containment of the main container volume.
Solution Approach 2:
The movable hood acts as an intermediary element between the operator and the waste contents. It provides a temporary opening mechanism that allows access to the filling opening while maintaining the sealed state of the lower body, thus mediating between the need for access and the need for containment.
2Ease of operation
If the filling opening remains open during collection, then ease of operation is improved, but toxic gas release into the environment increases
Solution Approach 1:
The forced air circulation device is activated before and during the waste collection process. It pre-establishes a controlled airflow that draws toxic gases away from the filling opening and directs them through the annular chamber to the column for containment, ensuring that even with the opening accessible, toxic gases are captured before release.
Solution Approach 2:
The system uses a forced air circulation device to create a controlled airflow that actively manages toxic gas transport. The air is forced through the annular chamber and into the column, creating a pneumatic barrier that prevents toxic gases from escaping while allowing the filling opening to remain accessible for collection operations.
3Object-affected harmful factors
If a forced air circulation system is added to capture toxic gases, then environmental protection is improved, but device complexity increases
Solution Approach 1:
The forced air circulation device, annular chamber, and column are merged into an integrated assembly that attaches to the container body. These components work together as a unified system for toxic gas capture, combining multiple functions (air circulation, gas transport, and containment) into a single attached structure rather than separate systems.
Solution Approach 2:
The column serves multiple functions: it acts as a containment structure for toxic gases, a transport conduit for air circulation, and a protective barrier against environmental release. The annular chamber simultaneously serves as a gas collection zone and an airflow channel, reducing the need for separate dedicated components.
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 design effectively captures and contains toxic gases within the container, ensuring they are not released into the environment, while maintaining ease of use by allowing the filling opening to remain open during collection.
Implementation Method 1
the column, which comprises a base, a top and at least one air outlet, extends, outside the body, in a manner adjoining said body, in that said column houses a forced air circulation device
Implementation Method 2
said column is, in the so-called active configuration of the container, in fluidic communication with the annular chamber by an airtight fluidic link
