Professional manufacture factory for waste incinerator, sewage treatment and sludge dewatering equipment.
In the field of industrial incineration, the treatment of pollutants such as dust, acidic gases, and heavy metals in flue gas remains a core environmental challenge. Shandong Better Environmental Protection Technology Co., Ltd. (hereinafter "Better Environmental") has independently developed the Wet Scrubber, a critical component of its WFS series incinerators, achieving over 99% pollutant removal efficiency and helping enterprises comply with the EU 2010/75/EU emission standards.

I. Working Principle: Three-Stage Purification Barrier
The wet scrubber employs a spray absorption + packed-bed filtration + cyclonic mist elimination integrated process:
Primary Spray Section: Alkaline solutions (NaOH/lime slurry) are atomized through high-pressure nozzles into micron-level droplets, neutralizing acidic gases like SO₂ and HCl with ≥98% removal efficiency.
Turbulent Packed Bed: Polypropylene (PP) Pall ring fillers expand gas-liquid contact area to 800 m²/m³, capturing PM2.5 particles via inertial impaction, reducing dust concentration from 5,000 mg/m³ to below 30 mg/m³.
Cyclonic Demister: Specially designed guide vanes aggregate and settle dust-laden droplets, ensuring outlet flue gas moisture content <50 mg/m³ and eliminating "white smoke".
II. Technical Advantages: Five Innovations Solving Industry Challenges
Corrosion-Resistant Duplex Steel Shell: Constructed with 2205 duplex stainless steel, resistant to Cl⁻ concentrations up to 20,000 mg/L, extending equipment lifespan to 15 years.
Intelligent pH Control System: Real-time sensors monitor circulating liquid alkalinity, with automated dosing modules stabilizing pH at 8.5–9.5, reducing alkali consumption by 30%.
Modular Design: The system is split into spray tower, pump station, and dosing unit modules, cutting onsite installation time to 3 days (60% faster than traditional setups).
Zero Liquid Discharge: Scrubber wastewater is recycled through sedimentation tanks → RO membrane filtration → evaporation crystallization, saving 36,000 tons of water annually.
Energy Optimization: Equipped with variable-frequency centrifugal fans, achieving energy consumption ≤1.8 kW·h per ton of flue gas treatment and reducing operating costs by 40%.
III. Application Scenarios and Empirical Data
Deployed in medical waste, chemical waste, and e-waste incineration projects:
Case 1: At a medical waste disposal center in Zhejiang, paired with a 10 t/d incinerator, the scrubber demonstrated post-18-month operation: dioxin emissions at 0.05 ng TEQ/m³ and Hg content <0.01 mg/m³, meeting China’s GB 18484-2020 standards.
Case 2: A Shandong chemical plant reduced annual PM emissions by 62 tons and SO₂ by 380 tons, securing ¥2.15 million in local environmental subsidies.
IV. R&D Capabilities and Certifications
As an MIIT-certified environmental equipment manufacturer, Better Environmental leverages its Weifang Air Pollution Control Engineering Technology Center and collaborates with China University of Petroleum to develop CFD flow-field simulation technology, reducing scrubber pressure loss to <1,200 Pa. The system holds ISO 12117 explosion-proof certification and 12 utility model patents, dominating market share in northern China.
The technological advancement of the wet scrubber underscores Better Environmental’s comprehensive "incineration + purification" solutions. Future integration of carbon capture modules will further amplify its ecological value in achieving China’s "Dual Carbon" goals.
