Importance of Fume Extractors in the Seven Tank Process for Safe and Efficient Metal Treatment

Fume Extractor in Seven tank process by Stratgem

Introduction

The Seven Tank Process is essential in industries like automotive, metal finishing, and manufacturing, where metal surfaces are cleaned and prepared for coating. This process involves the use of multiple chemical solutions that release hazardous chemical fumes, making it crucial to have an effective fume extractor system in place. Without proper extraction, these fumes can pose serious health risks to workers and lead to long-term environmental damage. The process typically includes degreasing, pickling, activation, phosphating, and rinsing stages—each requiring careful handling of corrosive and volatile chemicals. In this blog, we’ll break down each step of the Seven Tank Process, highlight where fume extractors are used, and explore why StratGem’s industrial fume extraction systems are a top choice for safety and efficiency. With advanced filtration technology and robust design, StratGem’s systems ensure cleaner air, regulatory compliance, and a safer workspace, all while minimizing downtime and maintenance costs.

What is the Seven Tank Process?

The Seven Tank Process is a multi-stage metal treatment method that includes degreasing, pickling, phosphating, and rinsing steps to clean and prepare metal surfaces. Each of the tanks in this process involves chemical reactions that generate toxic fumes, which need to be controlled using a reliable fume extractor to maintain a safe environment. Fume extractors play a key role in capturing and removing these hazardous fumes, ensuring compliance with air quality standards and safeguarding employee health.

Steps in the Seven Tank Process Requiring a Fume Extractor

Here’s a look at each step in the Seven Tank Process, where a fume extraction system is essential:

  1. Degreasing Tank
    • • Purpose: Removes oils, greases, and other contaminants from the metal surface using a degreasing solution.
    • • Need for Fume Extraction: Degreasing agents produce chemical vapors that can be harmful if inhaled. A fume extractor removes these toxic fumes, improving workplace safety.

  2. First Water Rinse Tank
    • • Purpose: Removes oils, greases, and other contaminants from the metal surface using a degreasing solution.
    • • Need for Fume Extraction: Degreasing agents produce chemical vapors that can be harmful if inhaled. A fume extractor removes these toxic fumes, improving workplace safety.

  3. Pickling Tank
    • • Purpose: In this stage, metal is treated with an acidic solution, often containing hydrochloric or sulfuric acid, to remove rust and scale.
    • • Need for Fume Extraction: Acidic vapors produced during pickling can be highly corrosive and toxic. An efficient industrial fume extractor is essential to capture these fumes, ensuring air quality and protecting equipment from corrosion.

  4. Second Water Rinse Tank
    • • Purpose: Another rinse removes any acid residues from the pickling process.
    • • Need for Fume Extraction: Although primarily water-based, the tank may still release traces of acidic fumes. Fume extractors are important here to maintain clean air and remove any lingering particles.

  5. Activation Tank
    • • Purpose: The activation tank contains a mild acid that prepares the metal surface for the phosphating stage.
    • • Need for Fume Extraction: Acidic fumes in this tank can be hazardous. Using a fume extraction unit is vital to ensure these vapors are effectively removed.

  6. Phosphating Tank
    • • Purpose: The phosphating process treats the metal surface to increase its corrosion resistance.
    • • Need for Fume Extraction: The phosphating chemicals release toxic fumes that need to be contained. A fume extraction system captures and filters these fumes, enhancing safety and compliance with air quality standards.

  7. Final Rinse Tank
    • • Purpose:A final rinse ensures that any remaining chemicals are washed off before drying.
    • • Need for Fume Extraction: While this tank primarily contains water, residual fumes may still be present. Industrial fume extractors prevent these from spreading and ensure a clean air environment.

Benefits of Using a Fume Extractor in Each Step of the Seven Tank Process

Using an industrial fume extractor in each step of the Seven Tank Process provides several key benefits:

  • Enhanced Workplace Safety: DSI systems are often more cost-effective compared to other pollution control technologies like wet scrubbers. They typically have lower capital and operational costs, making them attractive for industries looking to reduce emissions without breaking the bank.
  • Improved Indoor Air Quality: DSI systems can be relatively easy to install, and they can often be retrofitted onto existing infrastructure without requiring significant modifications. This ease of installation makes DSI a practical option for industries looking to quickly improve their environmental performance.
  • Extended Equipment Lifespan: DSI systems can be used to control a wide range of pollutants, including sulfur dioxide (SO2), hydrogen chloride (HCl), sulfur trioxide (SO3), mercury, and other acid gases. This versatility makes DSI a flexible solution for industries facing multiple emission challenges.
  • Increased Productivity: Unlike wet scrubbers, which require large amounts of water for the scrubbing process, DSI systems operate without using water. This can be advantageous in areas where water availability or disposal is a concern, and it also eliminates the need for wastewater treatment facilities.
