Powder Batching, Drying, Reaction
Involving various powder materials such as resins, pigments, pesticides and chemical fertilizers, the batching and mixing links generate high-concentration dust (500-3000mg/m³), and some materials are flammable, explosive, corrosive (such as acid-base powder) and toxic (such as pesticide powder); the drying and reaction links are accompanied by high-temperature and high-pressure environments, and dust is prone to chemical reactions with other substances; operations are mostly carried out in closed containers or pipelines, making dust collection difficult.
Flammable and explosive dust (such as resin powder and flour-like chemical raw materials) can easily cause explosions when exposed to static electricity and ignition sources, and leakage of toxic dust can lead to personnel poisoning;
Emission of toxic and harmful dust will pollute soil and water bodies, facing strict environmental accountability;
Dust mixing into the reaction system may affect product quality and even lead to reaction out of control;
Corrosive dust will damage the inner wall of equipment and shorten the service life of equipment.
Explosion-Proof Closed Dust Removal Solution
A fully closed dust removal system is adopted to realize the full-process closure of dust "generation - collection - purification - emission" to prevent dust leakage; for flammable, explosive, toxic and harmful dust, explosion-proof and poison-proof devices are matched.
Explosion-proof pulse bag filters, motors and fans select models with explosion-proof grade Ex d ⅡB T4 and above, filter bags select corrosion-resistant and anti-static filter materials (such as anti-static PPS filter materials), and are equipped with explosion vents and flame arresters to prevent explosion spread;
Cartridge filters are selected, equipped with activated carbon adsorption layers to adsorb toxic gases and dust, and discharge up to standard after purification;
Closed pipelines and dust hoods are adopted, the interfaces are sealed with gaskets, and dust concentration monitors are equipped to monitor dust concentration in real time.
According to the dust explosion characteristics, select equipment with corresponding explosion-proof grades. Motors, fans and electrical components must meet explosion-proof standards;
For acid-base dust, the equipment shell is made of stainless steel, and the filter material is made of corrosion-resistant filter material (such as PTFE);
The entire system adopts a closed design, and the interfaces are tightly sealed to prevent leakage of toxic and harmful dust;
Equipped with dust concentration, temperature and pressure monitors to monitor the equipment operation status in real time and warn of faults in a timely manner.

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.
