PP Fume Hood With Scrubber System

The PP fume hood with scrubber system is an integrated safety device for treating highly corrosive, acidic/alkaline waste gases in laboratories.

I. Core Definitions

• PP Fume Hood

• Cabinet: Made of polypropylene, highly resistant to acid and alkali corrosion.
• Application: Contains harmful gases when handling strong acids, strong alkalis, and highly corrosive reagents, protecting laboratory personnel.

• Scrubber System

• Integrated exhaust gas purification device (usually a wet scrubber).
• Principle: Chemical absorption + physical scrubbing, neutralizing/dissolving toxic exhaust gases before discharge to meet standards.

II. Workflow (Complete Purification Chain)

1. Gas Collection: Acid mist/exhaust gas generated in the experiment is drawn into the fume hood under negative pressure.

2. Scrubbing: Exhaust gas enters the scrubbing tower and comes into countercurrent contact with the spray liquid (such as NaOH, water).

3. Reaction: Acidic gases are neutralized, and particulate matter is captured (efficiency). >90%)

4. Demisting: Gas is dehydrated by the demister to prevent the carry-over of liquid droplets.

5. Discharge: Clean air is discharged by a fan; waste liquid is recycled or treated before discharge.

III. Standard Configuration (Integrated)

• Cabinet: Welded with corrosion-resistant PP board, resistant to strong acids/alkalis/organic solvents

• Washing Module:

          1. Spray nozzles (multi-layer/dual-path)

          2. Packing layer (Pall rings/Raschig rings)

          3. Circulating water pump + water tank

          4. Demister

          5. Online pH monitoring + Automatic Dosing

          6. Low Water Level Audible and Visual Alarm

• Control: Touch panel, VAV variable air volume, air speed monitoring

IV. Applicable Scenarios

•Highly corrosive experiments: HCl, HNO₃, H₂SO₄, HF, strong alkalis, chlorine, bromine, etc.

•Chemical synthesis, analysis, microelectronics, pharmaceutical, electroplating laboratories

•Places requiring zero pollution emissions and strict environmental protection standards

V. Advantages

1. PP material: Lifetime corrosion-resistant and rust-free

• Integrated design: Small footprint, easy installation
• High-efficiency purification: Acid mist removal rate 90–95%+
• Intelligent control: Automatic dosing, pH monitoring, alarm
• Safety: Personnel protection + compliant emissions
