2. Asphalt flue gas purification (activated carbon/low temperature plasma)
- Activated carbon adsorption tower: The flue gas enters the adsorption layer after being cooled to 40-60℃;The honeycomb activated carbon adsorbs harmful substances such as benzopyrene, and can be desorbed and regenerated at high temperature after saturation.
- Low temperature plasma technology: The high-voltage electric field ionizes the flue gas to produce highly active free radicals (such as OH);Free radicals decompose VOCs into CO₂ and H₂O, without secondary pollution.
- Customer benefits: The odor in the factory area is reduced by 80%, reducing residents’ complaints and employee health risks.
3. Recycled material addition technology (RAP ratio 30%-50%)
- Old material crushing and screening system: The milling material is crushed to ≤25mm by a double-shaft crusher;Multi-layer vibrating screen classification (0-5mm, 5-10mm, 10-25mm) to remove impurities.
4. Precise metering and blending
- RAP silo is equipped with weighing sensor and infrared moisture meter;The ratio of new material to old material is automatically adjusted according to the formula, with an error of ≤0.5%.
- Customer benefits: The cost of each ton of mixed material is reduced by 15-30 yuan, and the annual savings exceed one million yuan (calculated based on 100,000 tons/year).
Recycled Asphalt Technology
1. Warm mix asphalt (WMA)
- Foamed asphalt technology: Asphalt is pumped into the foaming chamber and injected with 2%-5% water;It expands instantly at high temperature (160-180℃), the volume increases by 10-20 times, and the aggregate is wrapped more evenly.
- Addition of organic viscosity reducer: Add fatty acid derivatives (such as Evotherm) to reduce asphalt viscosity;The production temperature is reduced from 160℃ to 120℃, and fuel consumption is reduced by 25%.
- Customer benefits: 3-5kg CO₂ emissions are reduced per ton of mixture, which meets the requirements of carbon trading policies.
2. High proportion of recycled material mixing (RAP>50%)
- Double drum hot regeneration technology: The outer drum heats the new aggregate to 200℃, and the inner drum preheats the RAP to 130℃ (to avoid aging of old asphalt);
- The new and old materials are mixed in the mixing area, and the fusion degree of new and old asphalt is increased to 95%.
- Precise spraying of regeneration agent: According to the degree of RAP aging (analyzed by fluorescence microscope), regeneration agent (such as aromatic oil) is added dynamically;Restore the ductility of old asphalt to ≥40cm (25℃).
- Customer benefits: When the RAP utilization rate reaches 60%, the material cost is reduced by 40%, and a subsidy of 30-50 yuan per ton is obtained from the local government.
Modular design: Rapid Response Engineering Adaptation
1. Container structure
