In the vast land of northwest China, the two industries of photovoltaic power generation and salt lake
lithium extraction are experiencing rapid development. These areas are prone to frequent sandstorms
and dust, posing a severe challenge to the ventilation and heat dissipation systems of core facilities
such as substations and computer rooms due to the presence of dust particles in the air.
The accumulation of dust inside the equipment affects the heat dissipation efficiency, which may
lead to equipment failure, shortened lifespan, and increased maintenance costs. How to effectively
resist sandstorms and ensure the stable operation of equipment has become a common concern in
the industry.
Addressing common challenges
Innovative solution for self-cleaning sand removal and filtration unit
In response to the ventilation challenges in high dust environments, self-cleaning sand removal and
filtration units have emerged. This product adopts an innovative V+T type filtration module and pure
mechanical structure, which can provide high air volume ventilation while efficiently removing dust
from the air, and achieve automatic cleaning and maintenance free operation.
Self cleaning sand removal and filtration unit
Core advantages of the product
01 Automatic centrifugal sand removal
The sand and dust are effectively separated by centrifugal force inside the unit and automatically
discharged outdoors, without the need for manual intervention, truly achieving unmanned operation.
02 High efficiency filtration performance
The filtration efficiency is over 95%, effectively blocking coarse and fine particles from entering the
interior of the equipment and protecting the rear air conditioning and ventilation system.
03 Low wind resistance modular design
The compact structure achieves high ventilation efficiency in a limited space, supports flexible
combinations, and adapts to the needs of different sites.
04 Long life maintenance free
No consumables, no need to replace filter element, significantly reducing maintenance costs
in the later stage, especially suitable for long-term use in harsh environments.
Application scenario extension
Extracting lithium from salt lakes to photovoltaic power plants
Qinghu Salt Lake Lithium Extraction Substation
The project is equipped with 4 units of GRD-A312 type (air volume 25000m ³/h) and 2 units of GRD-A422
type (air volume 60000m ³/h), effectively solving the problem of dust accumulation in the computer room
and ensuring the stable operation of power equipment.
Photovoltaic power stations in the northwest region
In multiple large-scale photovoltaic projects, self-cleaning sand removal and filtration units also play a key
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 technical
characteristics, is becoming the preferred ventilation solution in high dust environments in the industry.
Whether it is a lithium extraction substation in a salt lake or a photovoltaic power station in the desert, they
are silently guarding the "respiratory system" of the core equipment and ensuring the stable operation of
industry project bases.
