What is a WPC/SPC/PVC Pulse Dust Collector?

The WPC/SPC/PVC Pulverizer Pulse Dust Collector is a highly efficient and environmentally friendly system designed to work in conjunction with pulverizing equipment. It is mainly used to collect dust generated during the grinding process, ensuring clean production and compliance with environmental standards.

By adopting a “filtration + pulse jet cleaning” working mode, it maintains consistently high operational efficiency. It is widely used in industries such as building materials, chemicals, food, and pharmaceuticals.

Working principle of WPC/SPC/PVC Pulse Dust Collector:

The WPC/SPC/PVC grinding mill pulse dust collector mainly consists of filter bags, pulse valves, air storage tanks, dust hoppers, and a control system. Its operation is divided into two core stages:

A1: Filtration Stage: Dust-laden gas enters the dust collector through the inlet. Dust is trapped by the outer surface of the filter bags, while clean air passes through the filter material into the clean air chamber and is discharged. This process can capture fine particles as small as 0.3–0.5 μm, achieving a purification efficiency of over 99.9%.

A2: Pulse Cleaning Stage: When dust accumulation on the filter bag surface increases and resistance rises, the control system automatically triggers the pulse valve. High-pressure air (0.4–0.6 MPa) is instantly injected into the filter bag, causing it to expand and vibrate rapidly, shaking the dust into the ash hopper for discharge. This process takes only about 0.1 seconds, consumes little energy, and does not interrupt dust collection operations.

This “dust removal while working” design ensures long-term stable operation of the equipment and avoids the problem of reduced efficiency caused by clogging in traditional dust collectors.

Structure and Technical Configuration of WPC/SPC/PVC Pulse Dust Collector：

Structure: External filter pulse jet baghouse dust collector (offline cleaning type)

Filtration area: Designed based on the air volume handled; it is recommended to calculate based on a filtration velocity ≤ 1.0 m/min.

For example: If the air volume handled is 30,000 m³/h, then the required filtration area is ≥ 500 m² (30,000 ÷ 60 ÷ 1.0).

• Filter Bag Assembly

Filter media material: Polyester needle-punched felt + PTFE microporous membrane composite filter media (antistatic, temperature resistant to 130℃, instantaneous 150℃)

Filter bag size: Φ130×2450 mm or Φ160×6000 mm (customized according to equipment model)

Service life: ≥2 years (under reasonable dust removal + oil-free and water-free operating conditions)

Filtration accuracy: Capable of capturing particles ≥0.3μm, emission concentration <10 mg/m³ (superior to national standards)

• Dust Removal System

Cleaning Method: Offline pulse jet cleaning (avoids secondary dust generation during cleaning)

Pulse Valve: Right-angle solenoid valve, pressure resistance 0.8MPa, response time <50ms

Pulse Pressure: 0.5～0.7 MPa (adjustable)

Pulse Cycle: Automatically controlled based on pressure difference (recommended pressure difference threshold: 800～1200 Pa)

Cleaning Mode: Row-type spray, independent pulse jet pipe for each row of filter bags, ensuring uniform energy distribution

• Fan System

Fan Type: 4-72 high-efficiency centrifugal fan or Y4-73NO10D type
Power: 55kW～110kW (matching air volume)
Speed: 1450 r/min
Control Method: Variable frequency speed regulation, automatically adjusts air volume according to system resistance, saving 15%～20% energy

• Air Volume and Duct Design

Total processing air volume: 35,000～45,000 m³/h (adjustable; recommended design based on crusher dust generation × 1.2 safety factor)
Pipe material: Q235B steel plate, wall thickness ≥4mm
Connection method: Welding + flexible connector compensator to prevent vibration leakage
Air velocity control: Main duct air velocity maintained at 18～22 m/s, branch duct air velocity appropriately reduced

• Ash Hopper and Ash Discharge Device

• Ash Hopper Structure: Conical design with an inclination angle ≥60° to prevent ash accumulation and bridging.
• Unloader: Rotary rotary valve + double-layer pneumatic valve for airtight ash discharge.
• Auxiliary Devices:
• Pneumatic Vibrator (anti-sticking device)
• Level Gauge (high/low level alarm, automatic start/stop ash discharge)
• Insulation Layer (50mm rock wool added to prevent condensation when ambient temperature <5℃)

• Intelligent control system

Core Controller: PLC + Touchscreen HMI
Monitoring Functions:
Real-time differential pressure monitoring (range 0～5000Pa, accuracy ±1Pa)
Temperature monitoring (prevents overheating and bag burning)
Fault alarms (bag blockage, fan malfunction, ash removal failure)
Control Strategy: Fuzzy algorithm automatically adjusts ash removal frequency to reduce energy consumption
