Fully Enclosed Pickling Tunnel with Advanced Sealing for Acid Mist Control - China Suppliers and Factory Solutions
Product Details
Product Picture
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 solt sealing to prevent acid gas leakage.
🏗️ 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, confining acid mist to prevent escape.
★ Protects equipment and building structures by keeping the workshop free of acid mist.
🎛️ Control
★ Top with anti-corrosion lighting.
★ Negative pressure control system.
🛠️ Configuration
★ Top of tunnel with longitudinal sealing strip (PP flexible sheet).
★ Tunnel separated into process zones by rising/falling automatic doors.
★ External acid mist outlet connected to tower duct.
★ Observation window on the operating surface side.
Frequently Asked Questions
What materials are used for the pickling line tunnel structure?
The tunnel is constructed using PP (Polypropylene) reinforced panels supported by a steel cable connection structure for maximum durability and corrosion resistance.
How does the system prevent acid mist from escaping into the workshop?
The system utilizes an acid mist tower fan to create constant negative pressure inside the tunnel, combined with automatic isolation doors and slot sealing to confine all gases.
Are the automatic doors resistant to chemical corrosion?
Yes, the automatic doors feature steel supports with elements laid in FRP (Fiber Reinforced Plastic) and reinforced plastic panels designed specifically for acidic environments.
How is the visibility maintained inside the tunnel?
The tunnel is equipped with anti-corrosion lighting on the top and observation windows on the operating side for safe process monitoring.
What is the function of the telescopic shock-absorbing hose?
Each barrel trough is designed with these hoses and on-off valves, fixed by flange surfaces, to manage fluid flow while absorbing vibrations and mechanical stress.
