Solution Overview
Industrial exhaust systems often rely on pipeline networks to collect and transport VOCs and dust from multiple emission points. Proper design of pipeline capture, airflow balance, and ventilation is essential for stable operation, regulatory compliance, and workplace safety.
AuSSE provides integrated pipeline VOC capture solutions based on airflow simulation, balanced ducting design, and optimized capture hoods.
Industry Overview
In many industrial processes, VOC emissions come from feeding stations, washing areas, mixing tanks, and other equipment. These emissions are often:
Unorganized emissions — difficult to capture efficiently;
Affected by human movement and equipment layout — airflow patterns change;
High risk of leakage — especially near access points and open covers;
Complex flow characteristics — requiring careful design of capture devices and ducting.
Effective pipeline capture is vital for VOC removal and compliance with environmental standards.
Engineering Challenges
Ensuring capture hood placement matches VOC emission behavior;
Achieving airflow balance across branches and suction points;
Preventing VOC leakage during operation and access cover opening;
Avoiding excessive loss of raw material during exhaust;
Handling fluctuating VOC emissions without affecting production.
AuSSE Pipeline Capture and Airflow Balance Solution
AuSSE designs pipeline VOC capture systems that improve collection efficiency and maintain stable airflow throughout the ducting network.
Dual-Point Capture Hood Design
At material feeding points, we use a combination of upper and lower suction hoods:
The upper suction hood is placed close to the feed port to capture most VOCs.
The lower suction hood captures remaining VOCs and dust particles that escape the upper hood.
Enclosed Ventilation at Washing Areas
For washing or VAT cleaning operations:
Fixed suction hoods capture VOCs from washing operations.
Enclosed zones with transparent strip curtains form a temporary enclosure.
The enclosure uses slightly negative pressure ventilation to trap VOCs effectively.
This prevents VOCs from spreading into adjacent production areas.
Adjustable Ventilation Rates
Ventilation systems are designed with adjustable airflow rates:
This prevents VOCs from escaping when access covers are open.
It avoids unnecessary extraction of raw materials from tanks.
It maintains proper air volume under variable production conditions.
Design takes into account temperature rise and VOC volatility in the mixing process.
Placement Based on Emission Characteristics
Suction hood locations are determined by how VOCs are released. Placement is optimized to:
Avoid airflow interference;
Improve capture effectiveness;
Match real emission points on the production floor.
Balanced Ducting System
To ensure pipeline airflow balance, we install balancing dampers in all connecting branches:
Suction hoods
Tank ventilation outlets
Branch duct connections
Balanced ducting ensures even air volume distribution and stable operation of the entire system.
