I. Product Overview
The explosion-proof high-pressure misting system is specially designed for the demanding operating conditions of onshore and offshore oil and gas drilling platforms. The entire unit meets the Ex d II BT4 explosion-proof rating and is suitable for flammable and explosive oil‑gas work areas such as wellheads, solids‑control zones, and rig control rooms. It integrates four key functions—oil‑gas dilution and explosion protection, high‑temperature cooling, dust suppression in drilling operations, and static‑electricity elimination—leveraging advanced high‑pressure micro‑mist atomization technology and using clean water as the working medium. This system rapidly settles drill cuttings and dust, reduces the concentration of volatile hydrocarbons at the site, and mitigates the risk of flash‑over explosions, making it an essential safety and environmental‑protection device for drilling platforms.
II. Product Advantages
1. Explosion‑proof safety design for the entire unit: The motor, electrical control cabinet, and high‑pressure pump housing are all certified as explosion‑proof, effectively preventing electrical sparks from igniting flammable gases; the entire machine is constructed from 304 stainless steel, offering corrosion resistance to marine salt spray and drilling mud, making it suitable for harsh outdoor and offshore environments.
2. Fine atomization for efficient operation: A high-pressure pump generates an atomized droplet size of 8–30 μm, enabling the mist to adsorb suspended drilling dust and volatile hydrocarbons, achieving a dust suppression and vapor‑control efficiency of over 95%. Each spray boom provides coverage of 3–4 meters, with uniform mist distribution and no dead zones.
3. Intelligent Inverter‑Based Automatic Control: Equipped with an integrated temperature–humidity and oil‑gas concentration control system, it supports local manual operation as well as remote PLC‑controlled automatic start/stop. The spray water flow is continuously adjusted in response to on‑site temperature and oil‑gas levels, while automatic power‑off protection activates in case of water shortage or overpressure, effectively preventing pump damage due to dry running.
4. Energy- and water-saving with simple operation and maintenance: Water consumption is significantly lower than that of conventional spray systems, and the increase in material moisture content is less than 0.1%, without compromising the performance of drilling solids-control mud; the nozzles feature anti-clogging self‑relief pressure, and the pipeline automatically depressurizes upon shutdown to prevent dripping, resulting in low maintenance costs.
5. Flexible and versatile installation: Supports three mounting configurations—rig‑mounted fixed, skid‑mounted mobile, and derrick‑suspended—and utilizes high‑pressure, corrosion‑resistant seamless piping components, making it suitable for retrofitting both new and existing drilling rigs.
III. Scope of Applicable Operating Conditions
Onshore oil and gas drilling rigs, offshore drilling decks, drilling solids-control system areas, mud‑processing workshops, drill‑pipe maintenance zones, and shale oil and gas extraction facilities—all incorporate simultaneous cooling solutions to mitigate the high‑temperature conditions typical of summer drilling operations.
