As a core power equipment in the power and petrochemical industries, the cleanliness of turbine oil in steam turbines directly determines the operational efficiency and stability of the unit. Traditional filtration technology struggles to address pain points such as oil emulsification, increased acid value, and contamination from tiny particles. Qingdao Hainan Energy Environmental Protection’s electric adsorption purification and reduction technology provides a solution for the lubrication system of steam turbines.
Technical Principle and Core Advantages: The Haina electric adsorption purification technology utilizes specially crafted electrode materials to form a directional high-voltage electric field, actively adsorbing polar substances (oxidation products, acidic components, colloids), 0.1μm-sized solid particles, and moisture from turbine oil, simultaneously achieving demulsification, dehydration, and deep purification. Distinct from traditional passive filtration, this technology boasts three core advantages: High purification accuracy: It can elevate the cleanliness of the oil to NAS 5-7 level, reduce moisture to below 300, restore acid value to new engine oil standards, and lower the paint film tendency index.
Online operation: The modular design allows direct integration into the lubrication system, eliminating the need for downtime and adapting to the continuous operating conditions of the steam turbine.
Composite filter element substitution: Utilizing desorbable modified materials, it reduces the cost of consumables.
Industry pain points and application scenarios: During the operation of steam turbines, turbine oil is prone to deterioration due to the following issues: Moisture intrusion leads to emulsification, causing bearing wear and jamming of the regulating system.
The accumulation of oxidation products increases the acid value and corrodes equipment components.
Tiny particles cause damage to the oil film, shortening the lifespan of the unit.
Haina electric adsorption technology is applicable to three scenarios:
Online parallel connection of new units: purify residual impurities from installation, enhance system cleanliness, and extend oil product lifespan by over 30% Operating units:
online purification, address oil aging issues during long-term operation, and reduce unplanned downtime by 60% Maintenance and repair: quickly purify decommissioned oil products, reduce new oil procurement, and lower operation and maintenance costs Haina electric adsorption purification technology,
with its innovative model of “active purification + online operation + composite filter cartridge domestic substitution”, breaks through the bottleneck of traditional purification technology, providing a green lubrication system solution for the turbine industry. It helps achieve the dual goals of “energy conservation, consumption reduction, emission reduction, and efficiency improvement”, and promotes the industry’s transition towards high-quality sustainable development.
