Welding, Grinding, Cutting
Processing stainless steel, carbon steel and other metals, welding produces high-temperature metal fumes (containing heavy metal particles such as iron oxide, manganese and chromium) with particle sizes mostly ranging from 0.1 to 10μm; grinding/cutting produces a large amount of metal debris and dust with concentrations up to 500-2000mg/m³, some processes are intermittent, and dust emissions fluctuate greatly; the operating environment is mostly scattered workstations in workshops with complex spatial layouts.
Inhalation of heavy metal dust can cause occupational diseases such as pneumoconiosis and manganese poisoning, resulting in irreversible damage to the respiratory and nervous systems of workers;
Metal dust is combustible dust, and accumulation can easily cause dust explosions when exposed to ignition sources (such as aluminum powder and magnesium powder processing);
Untreated dust emissions exceeding standards violate the "Integrated Emission Standard of Air Pollutants" (GB 16297-1996), facing risks of fines and production suspension for rectification;
Dust adhering to the surface of production equipment can easily lead to equipment wear, reduced precision and increased maintenance costs.
Decentralized + Centralized Combined Dust Removal Solution
For decentralized workstations (such as welding and small-scale grinding), mobile welding fume purifiers are used for point-to-point purification; for centralized production lines (such as large-scale grinding workshops), central dust collection systems are used to collect dust from each workstation to the main unit for purification through pipelines.
Select high-negative pressure and low-noise models, equipped with HEPA high-efficiency filter cartridges (filtration precision ≥0.3μm, filtration efficiency ≥99.97%) to adsorb heavy metal fine particles;
The main unit selects pulse bag filters, the filter bag material selects high-temperature resistant and wear-resistant P84 filter materials, and is equipped with spark detection and extinguishing devices to prevent metal sparks from igniting the filter bags;
Closed dust hoods are set at grinding workstations to improve dust collection efficiency.
Priority is given to HEPA high-efficiency filters to ensure that heavy metal fine particles meet purification standards, with filtration efficiency ≥99.97%;
Determine the air volume according to the number of workstations and dust emissions. The air volume for a single welding workstation is recommended to be ≥1200m³/h, and the air volume for centralized production lines is equipped with 1.2 times the total emissions;
For combustible metal dust, explosion-proof equipment must be selected, equipped with spark detection and extinguishing devices;
For decentralized workstations, mobile equipment is preferred for flexible adjustment and space saving.

Answer: It can be judged in two ways: ① Third-party testing: Entrust a qualified environmental protection testing agency to test the dust concentration at the equipment outlet to ensure compliance with relevant standards such as the "Integrated Emission Standard of Air Pollutants" (GB 16297-1996); ② Equipment monitoring: Select equipment equipped with dust concentration monitors to view the real-time dust concentration data at the outlet and intuitively judge the purification effect.
Answer: The maintenance cost of dust removal equipment is relatively low, mainly including three parts: ① Accessory replacement: Filter materials (filter bags, filter cartridges) are the main wearing parts. The replacement cycle depends on the working conditions (generally 3-12 months). The replacement cost of high-quality filter materials accounts for about 5%-10% of the total equipment price; ② Energy consumption cost: The fan operates with electricity. Our equipment adopts high-efficiency and energy-saving fans, and the energy consumption is 15%-20% lower than the industry average; ③ Labor cost: Daily cleaning of accumulated dust and equipment inspection are simple operations that do not require special personnel on duty, resulting in low labor costs.
Answer: We ensure safety through "triple protection": ① Equipment explosion protection: Select motors, fans and electrical components with explosion-proof grades meeting industry standards, and the equipment shell adopts an explosion-proof design; ② Explosion suppression: Equipped with explosion vents, flame arresters and explosion suppression devices. Explosion vents can release pressure in an instant during an explosion, flame arresters prevent the spread of explosion flames, and explosion suppression devices can quickly extinguish explosion flames; ③ Monitoring and early warning: Equipped with dust concentration, temperature and pressure monitors to monitor the equipment operation status in real time. When parameters are abnormal, it automatically warns and shuts down to avoid danger.
Answer: The installation cycle depends on the project scale. Small-scale decentralized equipment (such as mobile welding fume purifiers) is simple to install and can be completed in 1-2 days; the installation cycle of large-scale central dust collection systems is about 7-30 days. We will communicate with customers in advance to formulate a reasonable installation plan, and try to choose production gaps and holidays for installation to reduce the impact on normal production; for large-scale projects, phased installation and commissioning can be adopted to ensure the normal operation of some production lines.
Answer: Universal use is not recommended. The dust working conditions (concentration, particle size, physical and chemical properties) of different industries are quite different. For example, heavy metal dust in metal processing, flammable and explosive dust in the chemical industry, and ultra-fine dust in the electronics industry have completely different requirements for equipment filtration precision, explosion-proof performance and material. Universal equipment cannot accurately adapt to working conditions, which may lead to substandard purification effects, equipment damage and even safety accidents. We recommend customizing exclusive equipment according to the specific industry working conditions.
Answer: If a fault occurs in the equipment, it can be handled in the following steps: ① Emergency shutdown: In case of serious faults (such as abnormal noise, peculiar smell, dust leakage), immediately cut off the equipment power supply to avoid expanding the fault; ② Contact after-sales service: Call our 24-hour after-sales hotline to explain the fault phenomenon, equipment model, working conditions and other information; ③ On-site processing: Technical personnel from nearby service outlets will arrive at the scene within 2-8 hours to troubleshoot and repair; ④ Emergency support: For key production links, we can provide temporary backup equipment to ensure uninterrupted production.
