Fully Enclosed Pickling Tunnel - High-Quality Solution from China Suppliers and Factory for Acid Mist Control
Product Details
Consists of PP plastic and steel structure stiffeners. It contains a sliding door made of reinforced plastic and driven by a motor. The upper part needs a seal.
The gas hood needs to have a supporting steel structure design.
Each barrel trough must be designed with an on-off valve and a telescopic shock-absorbing hose. Both the adjusting switch valve and the telescopic shock absorber hose must be fixed by the flange surface.
Each tank shall install slot sealing to prevent acid gas leakage.
Product Picture
Structure
- Tunnel - steel cable connection support and PP reinforced panels.
- Automatic doors - steel support with support elements laid in FRP.
Function
- Automatic control of the isolation doors inside the tunnel.
- The operation of the acid mist tower fan creates a negative pressure inside the tunnel, keeping the acid mist confined inside the tunnel.
- The production workshop is kept free of acid mist, protecting the equipment and the building structure.
Control
- Top with anti-corrosion lighting.
- Negative pressure control.
Configuration
- Top of tunnel with longitudinal sealing strip (PP flexible sheet).
- The tunnel is separated into several process zones by means of automatic doors that rise and fall.
- External side of the tunnel with acid mist outlet, connected to the acid mist tower duct.
- Observation window on the side of the tunnel at the operating surface.
Frequently Asked Questions
Q1 What materials are used to construct the pickling line tunnel?
The pickling line tunnel consists of PP plastic combined with steel structure stiffeners. The automatic doors are built with steel supports featuring support elements laid in FRP (Fiber Reinforced Plastic).
Q2 How does the system prevent acid mist from escaping into the workshop?
Acid mist is confined inside the tunnel by operating an acid mist tower fan to create a negative pressure. Additionally, each tank is fitted with slot sealing, and the top of the tunnel features a longitudinal PP flexible sheet sealing strip to prevent gas leakage.
Q3 How are the internal process zones separated inside the tunnel?
The tunnel is divided into multiple process zones using motor-driven automatic isolation doors made of reinforced plastic that rise and fall automatically.
Q4 What are the installation requirements for the barrel trough components?
Each barrel trough must be designed with an on-off valve and a telescopic shock-absorbing hose. Both the adjusting switch valve and the telescopic shock absorber hose must be securely fixed by the flange surface.
Q5 What control and observation features are included in the tunnel configuration?
The tunnel configuration includes anti-corrosion lighting at the top, negative pressure control, an external acid mist outlet connected to the tower duct, and an observation window on the operating surface side of the tunnel.
