In the vast lands of northwestern of China, the photovoltaic power generation and lithium extraction from salt lakes industries are experiencing rapid development.

These regions are characterized by frequent sandstorms and high levels of dust, posing a serious challenge to the ventilation and cooling systems of core facilities such as substations and equipment rooms.

Dust accumulation inside the equipment affects cooling efficiency, potentially leading to equipment failure, shortened lifespan, and increased maintenance costs.

How to effectively combat sand and dust and ensure stable equipment operation has become a key focus of the industry.

Addressing Common Challenges

Innovative Solutions: Self-Cleaning Sand and Dust Filtration Units

To address the ventilation challenges in high-dust environments, the self-cleaning sand removal filter unit has been developed.

This product utilizes an innovative V+T type filter module and a purely mechanical structure, enabling high-volume ventilation while efficiently removing sand and dust from the air, and achieving automatic cleaning and maintenance-free operation.

Self-Cleaning Sand Removal Filter Unit

Product Core Advantages

01. Automatic Centrifugal Sand Removal

Sand and dust are effectively separated within the unit through centrifugal force and automatically discharged outdoors. The entire process requires no manual intervention, truly achieving unattended operation.

02. High-Efficiency Filtration Performance

The filtration efficiency reaches over 95%, effectively preventing coarse and fine particulate matter from entering the equipment and protecting downstream air conditioning and ventilation systems.

03. Low-Drag Modular Design

The compact structure achieves high ventilation efficiency within a limited space, supporting flexible combinations to adapt to the needs of different locations.

04. Long Lifespan and Maintenance-Free Operation

No consumables and no filter replacement are required, significantly reducing long-term maintenance costs, making it particularly suitable for long-term use in harsh environments.

Extended Application Scenarios

From lithium extraction from salt lakes to photovoltaic power plants

Qinghu Salt Lake Lithium Extraction Substation

The project is equipped with four GRD-A312 units (air volume 25000 m³/h) and two GRD-A422 units (air volume 60000 m³/h),

effectively solving the problem of dust accumulation in the equipment room and ensuring the stable operation of power equipment.

Northwest China Photovoltaic Power Plants

In several large-scale photovoltaic projects, the self-cleaning dust removal and filtration units also play a crucial role in preventing dust intrusion, improving system power generation efficiency and equipment reliability.

The self-cleaning sand removal filter unit, with its high efficiency, reliability, and maintenance-free features, is becoming the preferred ventilation solution in high-dust environments across various industries.

Whether in substations for lithium extraction from salt lakes or in photovoltaic power plants in the desert, it silently protects the "respiratory system" of core equipment, ensuring the stable operation of industrial project bases.
