Innovative Accessories For Industrial Dust Filtration And Purification In Industrial Settings

Equipment Description:

1. Working principle
Treatment of dusty gas: dusty gas enters through the air inlet, coarse particles settle in the ash hopper due to gravity, and fine dust evenly adheres to the surface of the filter cartridge;
Purified gas penetrates the filter cartridge into the clean air chamber and is discharged through the fan.
Filtration stage: surface filtration: dust forms a dense dust layer to intercept subsequent particles;
Deep filtration: submicron particles are captured by diffusion and electrostatic adsorption through fiber gaps.
Clean and regenerate: after the pressure difference reaches the threshold, the pulse valve triggers a high-pressure airflow (0.6-0.7MPa) to impact the filter cartridge and peel off the dust layer;
After cleaning, the dust falls into the ash hopper and the filter cartridge restores air permeability.
‌3. Technical parameters and performance‌
‌Filtration efficiency‌: dust removal rate of 0.5μm and above ≥99.5%‌; ‌Air volume‌: single unit capacity can reach more than 2000m³/h, supporting large air volume combination design‌; ‌Temperature resistance‌: conventional filter cartridge temperature resistance ≤120℃, special materials (such as PTFE) can reach 260℃‌; ‌Service life‌: filter cartridge life ≥2 years, whole machine design life ≥20 years‌.
‌4. Application scenarios‌
‌Industrial field‌: automotive manufacturing, metal processing, chemical industry, cement, furniture spraying and other high dust concentration scenes‌; ‌Special working conditions‌: welding smoke, spray powder recovery, explosion-proof environment (equipped with anti-static filter material)‌. ‌5. Installation and maintenance‌
‌Installation requirements‌: reserve enough maintenance space, the aperture deviation of the flower plate is ≤±0.1mm, and the concentricity deviation of the nozzle and the filter cartridge is <1mm‌;
The compressed air pipeline needs to be equipped with a water separator and the pressure is stable at 0.4-0.6MPa‌.
‌Maintenance points‌: regularly check the damage/looseness of the filter cartridge and clean the dust accumulation in the ash hopper‌;
Clean the water separator and replace the pulse valve diaphragm and other wearing parts every 6 months‌.
‌6. Environmental protection and safety‌
Emission concentration ≤10mg/m³, meeting the GB16297-1996 standard‌;
Configure explosion-proof devices, overheating protection and PLC fault alarm systems to ensure safe operation under harsh working conditions‌.
Through modular design and intelligent control, the filter cartridge dust collector can significantly reduce energy consumption (saving 30%-50% energy compared with traditional equipment) and adapt to diversified production needs‌.

Main structures and components:

‌1. Box system‌
Box: welded with steel plates (thickness ≥4mm), including filter chamber, clean air chamber and ash hopper, with a pressure resistance of -8000Pa, ensuring sealing and structural stability‌.
The ash hopper is located at the bottom, with a side wall inclination angle of ≥60°, which is convenient for dust sedimentation and equipped with a rotary valve or screw conveyor for centralized ash discharge.
‌Flow guide device and air flow distribution plate‌: a flow guide device is set at the air inlet, and the dust-containing gas is evenly dispersed through the air flow distribution plate to avoid excessive local flow rate causing filter cartridge wear‌.
‌2. Filter cartridge assembly‌
Filter cartridge material‌: commonly used polyester fiber, PTFE coating, glass fiber or nanofiber, with a microporous structure, can efficiently capture 0.3-20μm dust particles, and the filtration efficiency is ≥99.9%‌.
Filter cartridge structure: folded design (star or honeycomb), single filter area of ​​20-30㎡ (3-5 times that of traditional bags), vertically installed on the flower plate to optimize the cleaning effect.
It consists of a top cover, a metal frame, pleated filter material and a base, supported by internal and external metal frames to ensure a stable structure.
‌3. Cleaning system ‌ ‌ Pulse jet device ‌: Compressed air (pressure 0.4-0.7MPa) blows the inner wall of the filter cartridge in reverse through the pulse valve and the venturi tube, causing the filter cartridge to expand, deform and peel off the dust. ‌ ‌ Supports offline three-state cleaning (filtration, cleaning, and static), reducing the "re-adsorption" phenomenon during cleaning. ‌ ‌ Control system ‌: PLC automatically adjusts the cleaning cycle, and the trigger conditions include timing control or pressure difference monitoring (threshold 800-1500Pa), balancing energy consumption and filtration efficiency. ‌ ‌ ‌4. Auxiliary system‌
‌Fan‌: Generates negative pressure to guide the flow of dust-laden gas. Some models are equipped with variable frequency speed-adjustable fans to meet the needs of different working conditions.
‌Electronic control device‌: Integrated pressure, temperature sensors and fault alarm system to monitor the operating status of the equipment in real time‌.
‌5. Other key components‌
‌Inlet/exhaust duct‌: The inlet duct contains an airflow adjustment device to control the gas flow; the exhaust duct exports the purified gas to the external environment‌.
‌Sealing structure‌: The connection between the box and the filter cartridge uses a high-precision flower plate (aperture deviation ≤±0.1mm) to ensure air tightness‌.
Through modular design and intelligent control, the filter cartridge dust collector achieves efficient dust removal in a compact space, which is suitable for a variety of industrial scenarios such as welding, spraying, and pharmaceutical manufacturing‌.
