Ion Exchange Resin Bed Vessel/Container - Technical Specifications

Product Specifications

Technical details and manufacturing context for Vessel/Container

Definition

In an ion exchange resin bed system, the vessel/container is the primary structural component that contains the resin media, distributes influent flow evenly across the bed, collects treated effluent, and withstands operational pressures. It typically includes inlet/outlet ports, distribution systems, and support structures for the resin. The vessel is designed to operate under specific pressure and temperature conditions, with reference design pressure ranging from 1.0 to 1.6 MPa and reference design temperature from -20 to 150 °C. These directory ranges are not values prescribed by GB/T 150.3-2024; confirm them on the vessel data sheet. Internal volume typically ranges from 5 to 50 m³, with inner diameter from 1000 to 3000 mm and height from 3000 to 8000 mm. Shell thickness is typically 8 to 30 mm, with corrosion allowance of 1 to 3 mm. Nozzle sizes range from DN50 to DN300. The vessel weight ranges from 2000 to 15000 kg. Surface finish is typically Ra ≤ 3.2 μm. Hydrostatic test pressure is 1.25 times design pressure, ranging from 1.25 to 2.0 MPa. Materials on file include Stainless Steel 316L, Fiberglass Reinforced Plastic (FRP), and Carbon Steel with Lining. Material grade Q345R is listed for carbon steel general service per GB 713. These values are directory reference ranges and must be confirmed for the actual model and application with the legal manufacturer or supplier. The vessel is a component in chemical manufacturing, specifically for ion exchange processes. It is not a standalone product but part of a larger system. The design must comply with applicable standards, such as GB/T 150.3-2024 for pressure-vessel design, GB/T 150.4-2024 for fabrication, inspection and testing, and GB/T 9119 for nozzle dimensions. The vessel's structural integrity is critical for safe operation, and regular inspection is required to detect corrosion, fatigue, or other degradation. The vessel's performance affects the efficiency of ion exchange, as proper flow distribution prevents channeling and ensures complete contact between the solution and resin particles. The vessel must be selected based on resin bed volume, operating conditions, and material compatibility. The listed standards are procurement references, not proof of certification or compliance. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The vessel provides a controlled environment where influent passes through the resin bed. It maintains proper flow distribution, prevents channeling, and ensures complete contact between the solution and resin particles for effective ion exchange. The vessel's design includes inlet and outlet ports, distribution systems, and support structures to manage flow and contain the resin. The vessel must withstand operational pressures and temperatures, and its internal geometry influences flow patterns. Proper design and operation are essential to avoid issues like channeling, which reduces efficiency, and to ensure the resin bed is fully utilized. The vessel also facilitates maintenance, such as resin replacement or regeneration. The working principle relies on the vessel's ability to contain the resin and direct flow evenly, ensuring that the ion exchange process occurs uniformly across the bed.

Frequently Asked Questions

What materials are available for the vessel/container?

The materials on file include Stainless Steel 316L, Fiberglass Reinforced Plastic (FRP), and Carbon Steel with Lining. The material grade Q345R is listed for carbon steel general service per GB 713. The choice depends on the application and media compatibility.

What are the typical design pressure and temperature ranges?

The directory reference ranges are 1.0 to 1.6 MPa for design pressure and -20 to 150 °C for design temperature. GB/T 150.3-2024 does not prescribe these fixed values; confirm both on the vessel data sheet.

How is the vessel size determined?

The internal volume typically ranges from 5 to 50 m³, with inner diameter from 1000 to 3000 mm and height from 3000 to 8000 mm. Selection is based on the resin bed volume and process requirements.
