Wind-Resistant Spray Dust Suppression System for Quay Crane Unloading Operations
Wind resistance of the ship unloader at Shougang Jingtang Iron & Steel United Co., Ltd. High-Energy Dust Suppression Project It sets forth the fundamental technical requirements for the system’s functionality, architecture, performance, manufacturing, supply, installation, and construction. Based on the customer’s actual wind‑resistance needs, our company conducted an on‑site assessment and engaged in extensive discussions and feasibility studies with Shougang Jingtang Co., Ltd. Guided by a rigorous, high‑precision service ethos, the project ultimately adopted advanced high‑energy micro‑mist dust suppression technology. A complementary micron‑scale, high‑energy atomization dust‑control system was installed to ensure virtually no visible dust during ship‑unloading operations. Furthermore, the spray‑system engineering incorporates specialized designs for the misting equipment, automated control, instrumentation, integration, and freeze‑protection, thereby increasing unloading speed and reducing operating costs.
Working Principle of the Wind-Resistant Dust Suppression System ； It consists of a high‑energy micro‑mist host unit, a filtration system, a water tank, an electric heating system, mist‑distribution piping, flexible coupling devices, adjustable atomizing nozzles, and an intelligent infrared control system. The infrared interface receives signals indicating the arrival of vehicles and relays them to the high‑energy micro‑mist host. The host then activates the internal high‑pressure pump and opens the solenoid valves, initiating misting. This creates a fine mist layer inside the material‑discharge area, preventing dust from becoming airborne and causing it to settle along with the tiny droplets, thereby achieving dust suppression and reduction.
Advantages of the wind-resistant dust suppression system; the system can achieve pressures of up to 15Mpa , can divide small water droplets into 10 Microns to 5 0 Micron-sized water droplets form a mist layer of a certain thickness above the dust‑generating source, enclosing the particulate matter within the mist. As airborne dust rises through this mist layer, the water droplets coalesce with the dust particles, causing them to aggregate and settle, thereby achieving dust suppression and air purification. The system is equipped with a heat‑trace system to ensure reliable operation even at subzero temperatures. 30 Normal use in a ℃ environment.
Components of the High-Energy Atomization Dust Suppression System
1 ) Pump station unit: Equipped with an imported high-pressure ceramic plunger pump, it offers stable pressure regulation and a variety of protective functions. With robust performance, reliability, and durability, it is capable of continuous operation.
2 ) High‑energy micro‑mist nozzle; employing proprietary, in‑house developed technology and operating on the principle of negative‑pressure atomization, it is manufactured using CNC machining, with a body made of… 316 Made of stainless steel, it features uniform misting, long spray range, fine droplet size, minimal wear, low pressure loss, and excellent dust suppression. Depending on functional requirements, different nozzle models can be selected; it maintains stable operating pressure and produces consistent mist particles. 10~50 Microns; the piping is connected with high-pressure-resistant stainless steel tubing, ensuring a service life of over ten years.
3 ) Water filtration system; the inlet is equipped with a fully automatic backwash filter that automatically removes sludge without manual intervention, followed by multi-stage filtration. RO Ultra‑strong filter, equipped with 5 Micron ultra-fine filters effectively address water quality issues, ensuring that nozzles remain unobstructed.
4 ) Control unit;
a Manual control unit: Customers can use manual push-button controls to turn the system on and off according to their specific needs.b Automatic control: The main unit is equipped with a German-imported ultrasonic wireless sensor control system that automatically detects signals and allows users to set start-up and shut-down times according to their needs (radar). / Infrared sensor control requires dedicated configuration by a qualified technician. PLC Parameters), the spraying equipment operates continuously or intermittently within the set time, requiring no operator supervision.
The entire system uses ultrasonic sensors to detect the material‑handling arm’s signal and initiate pre‑emptive spraying in the hopper. Once the hopper is fully enveloped in a mist, the grab bucket descends to begin discharging the material, while the main unit… PLC The automatic control system activates the spray system in the vehicle loading area, providing preemptive misting and significantly enhancing dust suppression.
Dust suppression effectiveness and equipment performance after commissioning
1 ) On-site dust concentration monitoring is carried out. GBZ/T 192-2007 “Determination of Dust in Workplace Air”: Total dust in the air is collected on a filter membrane of known mass, and the concentration of total dust in the air is calculated based on the mass gain of the filter and the volume of air sampled.
2 ) The on-site comprehensive dust suppression rate reaches 90% Above, no visible dust is apparent to the naked eye.
3) The high‑energy atomization dust suppression system requires minimal water consumption and supports both manual and fully automatic control modes.
