Hydrogen Cylinder Liner Drying Tunnel Oven

The Hydrogen Cylinder Liner Drying Tunnel Oven is a high-efficiency continuous drying system specially designed for the inner liners of vehicle-mounted high-pressure hydrogen storage cylinders (such as Type III and Type IV cylinders) after cleaning. The system adopts chain conveyor, mesh belt conveyor, or step-by-step conveying methods to transport the liners through multiple heating zones at a constant speed. Through precise temperature control and hot air circulation technology, the equipment quickly evaporates and removes residual moisture inside and on the surface of the liners, ensuring that the drying level meets the strict process requirements for subsequent filament winding or assembly.

Product Applications

Residual Water Drying:

Completely removes residual moisture from deep holes and micro-pores inside liners after cleaning.

Coating Curing:

Used for heat curing of anti-corrosion coatings applied on the surface of some metal liners.

Stress Relief Treatment:

Used for stress-relief heat treatment of plastic liners (Type IV cylinders).

Process Integration:

Provides seamless connection between the cleaning process and filament winding process in automated hydrogen cylinder production lines.

Technical Parameters

Product Features

Excellent Temperature Uniformity:

Specially designed fixtures prevent liners from rolling, collision, or surface damage during transportation.

FAQ

Q1: Is this tunnel oven suitable for plastic liners (Type IV cylinders) or metal liners (Type III cylinders)?

A: It is suitable for both types. The equipment supports independent temperature control in multiple zones and can accurately adjust the drying process according to the temperature resistance characteristics of plastic materials (such as PA6 and HDPE) or aluminum alloy liners.

Q2: How does the equipment ensure complete drying of moisture inside deep holes of the cylinders?

A: The equipment adopts a powerful hot air circulation system. Some models can be equipped with inclined conveying systems or low-pressure air ducts extending into the cylinder opening to ensure efficient removal of internal moisture.

Q3: Can the length and width of the drying tunnel be customized?

A: Yes. The equipment can be customized according to your production capacity requirements (such as the number of cylinders dried per hour), cylinder specifications (diameter and length), and factory layout.

Q4: What safety protection measures does the equipment have?

A: The system is equipped with over-temperature alarm and power-off protection, fan fault interlock protection, and conveyor overload protection. For high-risk environments, explosion-proof systems and gas concentration monitoring devices can also be added.

Q5: What advantages does a continuous tunnel oven have over traditional batch-type drying ovens?

A: The tunnel oven enables automated continuous production without frequent manual loading and unloading. It significantly improves production efficiency while ensuring more consistent heating and drying quality for each hydrogen cylinder liner.
