CE certified pulse bag filter: a compliant and efficient equipment for industrial dust control
Apr 23,2026
CE certified pulse bag filter is a core industrial dust control equipment exported to the European Union and in compliance with EU safety and environmental standards. It uses pulse jet cleaning as its core technology, and has the advantages of efficient dust removal, stable operation, and compliance access.
1、 Core working principle: filtering+pulse cleaning dual cycle
As a dry and efficient dust removal equipment, its operation revolves around the closed-loop of "gas-solid separation automatic cleaning continuous ash discharge", suitable for the vast majority of industrial dry dust scenarios:
1. Filtration and interception: The dusty gas is introduced through the air inlet, and the large particles of dust settle into the ash hopper by gravity. The fine particles follow the airflow to the filter bag area and are intercepted by the filter bag through inertial collision, diffusion, and screening. The purified gas is discharged through the filter bag.
2. Pulse dust cleaning: When the resistance caused by dust accumulation in the filter bag reaches 1200-1500Pa, the PLC system triggers the pulse valve, and compressed air is instantly sprayed onto the filter bag, causing it to expand and vibrate, peeling off the dust and falling into the ash hopper. The dust cleaning operation is thorough and does not stop.
3. Closed ash discharge: Dust from the ash hopper is regularly discharged through star shaped unloaders and screw conveyors to prevent secondary dust and ensure continuous operation.
2、 Core standards and compliance requirements for CE certification
The pulse bag filter exported to the European Union has CE certification as a mandatory entry threshold, covering four dimensions: mechanical safety, electrical safety, explosion prevention, and environmental protection
1. Basic directives: Follow the Machinery Directive 2006/42/EC and the Electromagnetic Compatibility Directive 2014/30/EU, corresponding to the standards EN ISO 12100 (Mechanical Safety Risk Assessment) and EN 60335 (Electrical Safety, Protection against Electric Shock, Overheating, Fire).
2. Explosion proof Special (ATEX): When handling flammable and explosive dust such as wood powder, metal powder, chemical powder, etc., it is necessary to comply with the ATEX directive, with electrical components reaching Ex explosion-proof level, equipped with explosion-proof discs, explosion-proof valves, and spark arresters.
3. Environmental protection and performance: Meet the EN 13776 filtration efficiency standard (≥ 99.5% for particles larger than 1 μ m), industrial emission directive IED (PM2.5 daily limit ≤ 5mg/m ³), and noise ≤ 85dB (at 1m).
4. Structural compliance: The pressure resistance of the box body is ≥ 5000Pa, the filter bag is sealed without short circuit, the service life of the pulse valve is ≥ 1 million times, and the overall air leakage rate is ≤ 3%.
3、 Core Performance Advantage (Suitable for Industrial Dust Control)
1. High dust removal efficiency: The efficiency of sub micron to coarse particle dust can reach 99.5% -99.9%, and the emission concentration can be stable ≤ 10mg/m ³, meeting the EU's ultra-low emission requirements.
2. Strong adaptability to working conditions: The filter material can be selected from normal temperature polyester, high temperature PPS/aramid, and corrosion-resistant PTFE coating, suitable for -20 ℃~260 ℃ flue gas, and resistant to high concentration dust (inlet ≤ 100g/m ³).
3. Stable and energy-saving operation: The pulse cleaning intensity is high, the cycle is short, and it maintains low resistance operation with low energy consumption; Modular design, single unit air volume ranging from thousands to millions of m ³/h, capable of parallel connection of multiple rooms.
4. Easy operation and maintenance: compact structure, no complex components, filter bag replacement can be operated offline, and only the pulse system, seals, and ash discharge device need to be inspected daily.
4、 Typical application areas
Widely applicable to industrial dust scenarios in the EU and compliant export markets:
1. Building materials cement: dust control at kiln head, kiln tail, mill, and crushing station
2. Metallurgical steel: High temperature flue gas purification for blast furnaces, converters, and electric furnaces
3. Chemical and pharmaceutical industries: drying, mixing, and packaging processes, collection of drying dust
4. Wood processing: sawdust, shavings, wood powder, explosion-proof dust removal
5. Grain and feed: Processing of light dust in the crushing, screening, and conveying processes
CE certified pulse bag filter is a dual compliant equipment for EU market access and efficient dust control. Its core is to achieve stable and efficient separation through filter bag filtration and pulse cleaning, strictly following EN mechanical, electrical, ATEX explosion-proof and environmental standards. When selecting, it is necessary to match the dust characteristics, flue gas temperature and humidity, and explosion-proof level, while considering compliance and dust removal efficiency, in order to achieve long-term standard treatment of industrial dust.
