Source capture and negative-pressure collection
Hoods and branch ducts collect workshop emissions and route them to the treatment train without uncontrolled escape.

Shaanxi Tongchuan Kaili New Materials — Exhaust Treatment — Case Study
Tailored VOC and reaction off-gas handling for specialty materials production.
Published project parameters checked
The published record covers a new-materials and catalyst manufacturing site with three separately documented exhaust duties. The treatment narrative combines source capture, wet pretreatment, zeolite-based VOC concentration and catalytic treatment, followed by odor polishing.

How the treatment train is configured
Published project record
Wet scrubber and mist eliminator
Removes soluble acid/alkaline components, coarse dust and entrained droplets before the VOC stage.
Published project record
Zeolite concentration and catalytic treatment
Concentrates the organic fraction before catalytic destruction, reducing the volume sent to the hot treatment stage.
Published project record
High-energy ion polishing
The source page describes a final polishing step for residual trace organics and odor.
Design and repeat-project checks
- The three airflows are published as separate design duties and are not presented here as one automatically combined fan duty.
- The website project description identifies mixed acid/alkaline gas, VOCs, dust, organic odor and trace hazardous impurities as the treatment challenge.
- Final fan static pressure, VOC mass loading, lower explosive limit assessment and outlet guarantee require the original process schedule and calculation package.
Evidence boundary
The public sources provide design airflows and a process narrative, but not signed inlet/outlet test data. This page therefore makes no independent removal-efficiency or compliance claim.
