To select an appropriate fluid iron remover for chemical raw material conveying pipelines, it is necessary to consider a variety of factors, including the physical properties, chemical properties, flow rate and pressure of the raw materials, as well as the material and structural design of the iron remover. Here are specific selection recommendations:

1. Selection Based on the Physical Properties of Chemical Raw Materials

Low-viscosity, free-flowing liquid raw materials: Such as water-based solvents, petroleum products, etc., a conventional pipeline-type fluid iron remover can be chosen. The pipe diameter should match the conveying pipeline, and the best iron removal effect is achieved when the material flow rate is controlled at 0.5 - 1.5 m/s.

High-viscosity raw materials or those containing solid particles: Such as coatings, inks, adhesives, etc., a pipeline-type fluid iron remover with a scraper cleaning device should be selected. This device can automatically clean the iron impurities and viscous materials adhering to the surface of the magnetic rod during operation, preventing blockages.

2. Selection Based on the Chemical Properties of Chemical Raw Materials

Corrosive chemical raw materials: Such as sulfuric acid, hydrochloric acid, sodium hydroxide solution, etc., the material of the iron remover must have good corrosion resistance. Iron removers made of stainless steel, Hastelloy, titanium alloy, and other corrosion-resistant materials can be selected, and the magnetic rod's covering layer can be made of corrosion-resistant materials such as polytetrafluoroethylene (PTFE) or PPS.

3. Consideration of Flow Rate and Pressure

Flow rate: Choose a fluid iron remover with a suitable pipe diameter based on the flow rate to ensure smooth material passage.

Pressure: The rated pressure of the iron remover should be 1.2 - 1.5 times higher than the actual operating pressure of the pipeline to ensure the safe operation of the equipment.

4. Selection of Iron Remover Structure and Function

Automatic iron removal function: For continuous chemical production processes, selecting a fluid iron remover with an automatic iron removal function can reduce downtime and improve production efficiency.

Multi-layer filtration structure: Modern fluid iron removers often use a multi-layer filtration structure, which can enhance the iron removal effect.

High-temperature adaptability: If the chemical raw material is a high-temperature fluid, an iron remover made of high-temperature-resistant materials and equipped with a special cooling system should be selected.

5. Other Considerations

Magnetic strength of the iron remover: A fluid iron remover with a magnetic rod diameter of 25 mm can achieve a maximum magnetic strength of 12,000 Gauss, which is suitable for places with high requirements for iron impurity content.

Customized design: Based on specific process requirements, customized fluid iron removers can be selected to meet special requirements for flow rate, pressure, temperature, or chemical environment.

By following the above selection recommendations, it is possible to better choose a suitable fluid iron remover for chemical raw material conveying pipelines, ensuring the high purity of chemical raw materials and the smooth progress of the production process.
