The Operational Challenge in Open-Pit Mining Diesel supply chains in open-pit mining and field operations face severe environmental challenges, including high levels of dust and salt fog. Heavy machinery, such as haul trucks and excavators, requires large volumes of diesel. However, standard diesel logistics in these environments frequently suffer from particulate contamination, including airborne dust and equipment rust. Traditional vehicle filters typically rely on disposable paper or synthetic fiber elements. In high-dust environments, these filters reach their dirt-holding capacity rapidly, leading to frequent replacements, increased hazardous waste disposal costs, and significant equipment downtime. Furthermore, the bumpy conditions of field transport can cause traditional filter elements to loosen and fail.
Rigid Membrane Technology: A Structural Shift To address the limitations of conventional filtration media, JINGYUAN utilizes high-polymer rigid composite membranes. Unlike flexible fiberglass or paper, this material features a wall thickness of up to 5mm, providing high mechanical strength and shock resistance suitable for extreme field conditions.
The core filtration mechanism relies on an asymmetric gradient pore structure. This design allows for dual-action purification: surface sieving for hard particulates and deep-pore polar adsorption for soft impurities like oxidation gums. This ensures effective interception without the membrane undergoing physical deformation under pressure fluctuations.
Gas Pulse Regeneration: The Mechanics of Zero Consumables The primary driver for reducing Operating Expenses (OPEX) is the elimination of frequent filter replacements through online regeneration. The process, known as Gas Pulse Regeneration, operates purely on physical fluid mechanics:
- Monitoring: The system operates under a standard pressure of 0.2 to 0.35 MPa. As impurities accumulate on the membrane surface, the pressure differential rises.
- Pulse Activation: When the pressure gauge indicates a predefined high level (e.g., 0.5 MPa), the system requires maintenance. Instead of replacing the element, operators introduce compressed nitrogen or air at 0.5 to 0.7 MPa.
- Filter Cake Dislodgement: A 30-second reverse gas pulse is executed. The gas expands from the inside out, instantly breaking apart the filter cake of dust, rust, and gums attached to the outer membrane wall.
- Recovery: The concentrated impurities settle to the bottom of the housing and are discharged through a drain valve, instantly restoring the membrane flux to over 95% of its initial capacity.
Impact on OPEX and TCO By integrating this regeneration technology into equipment like the JY-Q325 containerized mobile filtration station (capable of 40 m³/h flow rates ), mining operators can achieve a filter element lifespan of 2 to 3 years. This continuous operation, devoid of chemical cleaning agents or frequent consumable purchases, effectively lowers the Total Cost of Ownership (TCO) by 60%.
