Pneumatic conveying solution for molecular sieves
In industries such as petrochemicals, air separation, and refrigeration, molecular sieves, as key adsorption and drying materials, have long faced numerous challenges in their transportation. Low manual handling efficiency, dust pollution from the environment, material damage leading to reduced adsorption performance, and pipeline blockages affecting continuous production—these issues not only increase operation and maintenance costs but also restrict the improvement of production line stability. How to achieve sealed, efficient, and low-damage conveying of molecular sieves has become an urgent issue for industry users.
Molecular sieve material characteristics
Molecular sieve is a porous, crystalline adsorbent material that appears as spherical or strip-shaped particles, usually ranging from 1 to 8 mm in diameter, with a bulk density of about 0.6-0.9 g/cm³. Its surface structure is stable but its internal structure is fragile, making it sensitive to wear and impact; It also has strong hygroscopic properties; exposure to air quickly absorbs moisture, leading to performance degradation. Therefore, during conveying, it is recommended to control airflow speed, minimize collisions, keep dry, and avoid material crushing and moisture exposure.
Head powder molecular sieve pneumatic conveying solution
Head Powder focuses on pneumatic conveying of powder and granular materials, and has developed a complete set of pneumatic conveying system equipment tailored to the characteristics of molecular sieves. This scheme uses a positive pressure dense phase pneumatic conveying method, powered by compressed air, to smoothly transport molecular sieve through sealed pipelines in the form of plug or plunger flow. The system consists of a feeding device, sending tank, delivery pipeline, gas source equipment, terminal separation device, and automation control system, and can be customized according to user site layout, conveying distance, and production capacity requirements.
Whether transporting from ton bags or storage silos to adsorption towers, dryers, packaging machines, or in-house multi-point feeding and recycling, Head Powder can provide complete solutions from single equipment to full-line integration. The system supports PLC automatic control, enabling quantitative feeding, continuous conveying, fault alarms, and other functions, supporting intelligent and traceable production processes.
Solutions for customer pain points
Solving material damage issues:Uses low-flow dense phase conveying technology, controlling material velocity within the pipeline at 3-8 m/s. Combined with wear-resistant linings at elbows and reducers, it effectively reduces particle collision and breakage, maintaining stable molecular sieve adsorption performance.
Solving dust and pollution issues:The entire system operates in a sealed manner, equipped with high-efficiency dust collectors and pneumatic recovery devices to achieve dust-free operations. During conveying, the molecular sieve does not come into contact with the outside world, preventing moisture absorption or impurities and helping to maintain material cleanliness.
Solving blockages and shutdowns:Pipeline design combines material flow testing to optimize gas-solid ratio and sending pressure, equipped with automatic blockage control logic. Key areas are equipped with pressure monitoring and automatic cleaning functions to reduce the probability of blockages and improve system operational reliability.
Solving energy consumption and O&M cost issues:Using variable frequency energy-saving gas source equipment and intelligent control algorithms, it automatically adjusts the air supply volume according to actual conveying conditions, saving 20%-35% more energy than traditional dilute-phase conveying. Modular design facilitates routine maintenance and reduces unplanned downtime.
