DCE Normal Temperature Filter Cartridge - Detailed Product Description

As a high-performance core component for DC dust collectors, the DCE Normal Temperature Filter Cartridge from Techrise (a brand under Shanghai Techrise Composite Material Co., Ltd., affiliated with Hongsheng New Materials) delivers a more reliable industrial dedusting solution. Backed by 22 years of professional expertise and a commitment to environmental protection, it addresses critical pain points in industrial dust management while ensuring efficiency, durability, and cost-effectiveness.

1. Core Product Specifications & Technical Data

1.1 Material & Filtration Performance
• Filter Material:
Adopts high-quality filter materials (with proprietary membrane technology); self-produced membranes ensure controllable quality, verified by over 20 years of industry application.
• Filtration Accuracy: Features strong fine dust capture ability, effectively improving exit emissions (test data shows optimized particle retention; dust emission can reach PM < 10mg/Nm³ in practical applications, as seen in Hebei Xinda Steel’s project).
• Corrosion & Environmental Resistance: Excellent corrosion resistance, moisture resistance, and good hydrophobicity; suitable for normal-temperature industrial environments, avoiding issues like material peeling or cracking.

1.2 Dimensions & Structural Design
• Length:
Maximum available length is 8 meters; common specifications include 130x2000mm, 130x2400mm, 160x1500mm, 160x3000mm, etc. (customizable for specific needs).
• Filtration Area: 2-4 times larger than conventional polyester felt filter bags, significantly enhancing dust-holding capacity without increasing equipment footprint.
• Structural Advantages: One-piece integrated structure (end closure and reel frame welded via proprietary technology); eliminates delamination risks common in sewn/glued filter bags, ensuring long-term stable operation.

2. Key Technology & Performance Advantages

2.1 Proprietary Manufacturing Technologies
• Automated Welding Process: Uses Fanuc (Japan) equipment for proprietary independent welding of end closures and reel frames, guaranteeing structural stability and efficiency.
• Precision Strapping Technology: Adopts advanced fully automated strapping; heat-sealing position accuracy is strictly controlled, with adjacent strap spacing error within ±0.1mm. This ensures stable system differential pressure, uniform airflow distribution for pulse jet cleaning, and reduced energy consumption.
• Advanced Sealing & Reinforcement: Longitudinal sealing (02 Longitudinal Sealing) enhances structural integrity.◦ Ultrasonic welding for end closure (03 Taping Techniques): Beautiful, solid, and corrosion/impact-resistant; no cracking risks compared to traditional sewing/gluing.◦ High-quality stainless steel continuous perforated inner mesh (06 Intranet Technology) provides strong support, preventing filter material deformation.

3. Installation, Maintenance & Cost Efficiency

3.1 Installation Details
• Installation Mode: Vertical installation, compatible with most DC dust collector systems.
• Retrofit Convenience: Replaces filter bags directly to increase filtration area—no need for equipment modification or expansion. Saves land, materials, and labor costs compared to traditional system overhauls.

3.2 Maintenance & Service Life
• Maintenance Requirements: Minimal maintenance; pulse jet cleaning works with uniform airflow (thanks to precision strapping), reducing filter clogging.
• Service Life: Extended by moisture resistance, reduced surface resistance, and flame-retardant property improvements (specific life cycle varies by industry, but typical applications show 30% longer service than conventional filter bags).

3.3 Cost Benefits
• One-off Investment: Smaller equipment size for the same treatment capacity, lowering initial investment .
• Operating Costs: Low system differential pressure reduces energy consumption; longer service life decreases replacement frequency and labor costs.

4. Quality Assurance & Credentials

• R&D & Patents: Techrise’s parent company (Hongsheng) has applied for 236 patents, with 139 authorized patents (including 37 invention patents), reflecting strong technical strength.
• Production Scale: Annual filter bag production length is equivalent to 10 Silk Roads, ensuring stable supply capacity.
• Customer Trust: Serves over 5,000 enterprises globally; mature applications in cement, power, metallurgy, steel, and chemical industries.

5. Typical Industry Applications & Cases

The DCE Normal Temperature Filter Cartridge is widely used in high-dust industrial scenarios, with proven performance in:
•Steel Industry: Coke dry quenching, sinter machine talings, blast furnace tapping, ore bins, lime kilns, converter steelmaking (e.g., Hebei Xinda Steel, WISCO Echeng Steel).
• Cement Industry: Coal mills, cement mills, clinker silo top environmental dedusting (e.g., Dalian Cement Group, Hangzhou Lin’an Southern Cement).
• Power & Chemical Industry: Coal-fired power belt conveying, ash silo dedusting; chemical coking (e.g., Panzhihua Feihuang Haifeng Coking).Case Example: Hebei Xinda Steel Co., Ltd. (Steel Industry)• Specification: Φ160×3000mm
• Commissioning Date: June 2023• Performance: Operates stably, dust emission ≤10mg/Nm³, meeting national environmental standards.
