Dust filter and air filter

Dust filter and air filter

. filtration accuracy

• definitionThe interception ability of unit micron pore size structure for particulate matter.

• typical value：

• Industrial grade: 10-100 μ m (coarse dust removal, PM10 or above)

• High precision: 0.1-1 μ m (HEPA/ULP, below PM2.5)

• effect：

• Coarse filtration: intercepts large particles of dust (such as sand, gravel, and metal shavings) to protect downstream equipment.

• Fine filtration: removes respiratory dust (such as PM2.5 and viral aerosols) to ensure air quality.

2. Hold Capacity

• definitionThe mass of pollutants that the filter can hold before clogging (g/m ²).

• typical value：

• Fiber filter cartridge: 50-200g/m ²

• Metal mesh filter: 100-500g/m ²

• effect：

• High dust holding capacity extends the replacement cycle and reduces maintenance costs (industrial scenarios can save 30% of consumables costs).

3. Differential pressure characteristics (Delta P)

• definitionThe pressure difference of the airflow before and after filtration (reflecting the degree of blockage of the filter element).

• typical value：

• Initial pressure difference:<10-20Pa (high-efficiency filter element)

• Termination pressure difference:<50-100Pa (threshold needs to be changed)

• effect：

• Low initial pressure difference reduces energy consumption (such as annual electricity savings of up to $10000+for large-scale dust removal systems).

4. corrosion resistance

• Technical Specifications：

• Material pH tolerance range: 1-14 (such as ceramic fibers, PTFE membranes)

• Temperature tolerance: -20 ℃~+600 ℃ (special ceramic filter element)

• effect：

• Suitable for harsh working conditions such as chemical exhaust gas (including acid/alkali) and high-temperature furnace exhaust gas.

5. service life

• influencing factors：

• Dust concentration (high concentration reduces lifespan by 30% -50%)

• Operating environment (humidity>80% can easily cause fiber clumping)

• typical value：

• Industrial filter cartridge: 2000-5000 hours

• Household filter cartridge: 3-6 months

2、 Actual application scenario effectiveness

1. Industrial dust removal

• caseCement plant cyclone separation filter element

• efficacyPM10 particle interception rate ≥ 95%, reducing annual maintenance costs by 40%.

• Technical keyWear resistant ceramic fiber+self-cleaning design (adjustable blowback frequency).

2. air purification

• caseHEPA filter in hospital operating room

• efficacyThe removal rate of particles ≥ 0.3 μ m in the air is ≥ 99.97%, which meets the ISO Class 5 cleanliness standard.

• Technical keyStatic polarized glass fiber+multi-layer composite structure.

3. Automobile exhaust treatment

• caseDiesel vehicle DPF (particulate filter)

• efficacyPM emissions reduced by 90%, meeting EU Stage V emission regulations.

• Technical keyHigh temperature resistance (250 ℃) and catalytic oxidation coating of cordierite ceramic fiber.

4. food processing

• case316L stainless steel antibacterial filter cartridge

• efficacyIntercept microorganisms (such as Escherichia coli) and comply with FDA hygiene certification.

• Technical keySurface electrolytic polishing (Ra ≤ 0.4 μ m), antibacterial coating (silver ion).

3、 Additional feature enhancement

1. Intelligent Monitoring

• technical implementationEmbedded differential pressure sensor+IoT communication

• effect：

• Real time warning of filter blockage (50 hours advance notice).

• Upload data to the cloud and generate maintenance work orders (such as Bosch Rexroth 4D intelligent filter).

2. Self cleaning ability

• Technical Type：

• Reverse pulse blowing (compressed air, 0.3-0.6MPa)

• Ultrasonic oscillation (28kHz frequency, suitable for viscous dust)

• effect：

• Reduce the frequency of manual intervention (extend the maintenance cycle of mining equipment by three times).

3. energy recovery

• Innovative DesignCyclone separation filter element+waste heat recovery system

• effect：

• Exhaust gas temperature recovery rate ≥ 30%, reducing overall energy consumption (such as 20% energy savings in steel plants).
