Unique composite Hybrid Electrochemical Scrubber Apparatus

Chapter 1: Background of Technological Innovation in Waste Gas and Wastewater Treatment Equipment Driven by Environmental Protection Needs

Under the global trend of rising environmental awareness and increasingly stringent pollution control standards,
traditional exhaust gas and wastewater treatment systems commonly face issues such as high energy consumption, low efficiency, and the tendency to generate secondary pollution.

The Hybrid Electrochemical Scrubber Apparatus
innovatively integrates physical water-scrubbing technology with electrochemical technology,
achieving dual objectives of multi-pollutant synergistic treatment and energy conservation with carbon reduction.

It has become a core pollution control solution widely applicable to multiple industries—
including semiconductors, chemical processing, food manufacturing, electric power, and steelmaking—
effectively filling the technological gap left by conventional systems.

Chapter 2: Understanding Traditional Cleaning Technologies and Comparing Their Limitations

(1) Core Parameters of Traditional Water-Vortex Scrubbing Equipment

Category	Detailed Description
Operating Principle	Relies purely on physical mechanisms (without auxiliary energy-consuming devices) to remove dust and odor pollutants in exhaust gas through the process of “airflow stabilization → vortex scrubbing → gas-liquid separation.”
Core Structure and Steps	1. Inlet Stage: Pollutants enter the “pressure-stabilizing chamber” under negative or positive pressure, where the airflow is decelerated and stabilized, laying the foundation for subsequent treatment. 2. Scrubbing Stage: The stabilized airflow enters the “helical vortex water-scrubbing chamber,” where vortex motion enables full gas-liquid contact, capturing pollutants effectively. 3. Separation and Exhaust Stage: The scrubbed gas passes into a “deceleration and pressure-stabilization chamber,” where mist droplets settle back into the water tank by gravity, and the purified gas is discharged through a dedicated outlet.
Technical Advantages	1. Simple Structure: Compact design without complex components. 2. Energy-Saving and Eco-Friendly: Operates without pumps, nozzles, or consumables; energy consumption is 50–70% lower than conventional systems. 3. Easy Maintenance: Fewer failure points; maintenance intervals are 3–5 times longer than those of traditional equipment.

(2) Core Deficiencies of Traditional Scrubbing Towers

High Energy Consumption: Dependence on pumps, piping, and nozzle spray systems, together with packing materials (e.g., Raschig rings), increases airflow resistance, requiring greater power and raising operational costs.
Unstable Efficiency: Insufficient gas–liquid contact results in low removal efficiency for fine particles and low-solubility VOCs (typically ≤70%).
High Maintenance Costs: Frequent clogging of nozzles and degradation of packing materials require regular cleaning and replacement, while generating secondary pollution such as oily wastewater and spent packing waste.

Chapter 3: Core Technology of Hybrid Electrochemical Scrubber Apparatus: Design Principles and Innovation Points

The Hybrid Electrochemical Scrubber Apparatus is designed based on the core logic of
“precise flow control → deep degradation → high-efficiency separation,”
integrating both physical and electrochemical technologies.
Key module parameters are as follows:

(1) Precise Flow Control: Scientific Design of Air Velocity, Volume, and Pressure Differential

Control Section	Design Logic	Technical Parameters and Effects
Inlet Parameter Matching	Adjusts air velocity and flow rate dynamically according to the characteristics of the treated medium (pollutant concentration, particle size).	1. For large industrial dust particles (≥10 μm): internal duct velocity increased to 15–20 m/s (vs. 10–12 m/s in conventional systems), raising capture efficiency from 85% to over 95%. 2. For low-concentration fine pollutants (PM2.5, oil mist): velocity controlled at 5–8 m/s; “multi-channel air inlets” create a negative-pressure vortex, improving subsequent degradation efficiency by 25%.
Internal Deceleration and Pressure Stabilization	Optimizes guide vane angles to reduce airflow velocity, forming a “decelerated and pressure-stabilized state.”	1. Velocity transition: 15–20 m/s → 5–9 m/s. 2. Flow-field effect: pollutant floc layer stably depresses the water surface, forming a uniform water film; gas–liquid contact rate improved from ≤70% to 95%. 3. Reaction time: residence time extended from 0.3–1 s to 2–3 s; VOCs degradation rate raised from ≤65% to over 90%. 4. Pressure loss control: optimized duct geometry and vane angles reduce pressure loss to 105 mmaq (vs. 140 mmaq in traditional systems); fan power demand reduced by 33%.

(2) Engineering Application of Bernoulli’s Principle: Acceleration by Constriction and Sustained Deceleration

Structural Design	Operating Principle	Technical Effects
Inlet Constriction Acceleration	A narrowed inlet is applied; according to Bernoulli’s law (velocity inversely proportional to pressure), airflow velocity increases.	1. Velocity change: 5–9 m/s → 12–15 m/s. 2. Core effect: high-speed airflow generates shear force, dispersing pollutant agglomerates (oil films, particle clusters), allowing pollutants to exist as single molecules/particles; gas–liquid and electrode contact area increased by ≥200%.
Helical Guide Zone Deceleration	Cross-sectional area of the guide zone is 2–3 times larger than the constriction, reducing airflow speed.	1. Velocity change: 12–15 m/s → 3–5 m/s, forming a “low-speed reaction zone.” 2. Core effect: the helical structure induces rotational contact between gas and liquid; multilayer parallel electrodes arranged along the helix allow pollutants to pass through the reaction zone multiple times (equivalent to 10–20 treatments); odor molecule removal efficiency reaches 98% (vs. 60% in linear designs).

(3) Electrochemical Technology: Characteristics and Degradation Mechanism of Multilayer Parallel Electrodes

1. Structural and Electrochemical Characteristics

Category	Design	Technical Advantages
Structural Features	1. Multiple sets of parallel electrode plates (including primary treatment and secondary purification electrodes). 2. Compact multilayer arrangement, typically 10–25 layers.	1. Flow stabilization: Guides vortex flow orderly through electrode arrays, avoiding turbulence; pressure loss reduced by >33%, no dead zones. 2. Maximized reaction area: Under the same volume, reaction surface is 10–20× larger than in water vortex flow; oil mist degradation efficiency +35%. 3. Progressive purification: First set removes >90% of high-concentration pollutants; second set targets residual micro-pollutants; final discharge ≤5 mg/m³ (vs. 15–20 mg/m³ conventional).
Electrochemical Properties	1. Anode: Fe/Al composite coating (e.g., RuO₂–IrO₂ titanium-based anode). 2. Cathode: stainless steel. 3. Fuzzy pulse current applied.	1. Controllable redox ability: Anode releases Fe²⁺, Al³⁺, and strong oxidative radicals (Cl·, ·OH; redox potentials 2.4 V, 2.8 V), decomposing organic pollutants and heavy metals. 2. Non-toxic byproducts: Cathodic electrolysis produces OH⁻, maintaining pH 6.5–7.5, neutralizing acids and reducing intermediates (nitrites, organic acids) to N₂ and H₂O; no secondary pollution. 3. Pulse current advantage: Reaction time shortened to milliseconds (oil degradation 0.5–2 s), efficiency +200%; prevents electrode passivation; maintenance cycle extended to 180 days (vs. 30 days conventional); energy consumption reduced by 30–50%.

2. Pollutant Degradation Pathways in Electrochemical Reactions

Pollutant Type	Degradation Principle
Water Mist	High-surface-area mist rapidly electrolyzed under strong electric field into H₂ and O₂, more efficient than liquid water.
Oils / Oil Mist	1. Anodic Fe³⁺ breaks “water-in-oil” emulsion structure (demulsification efficiency 90%). 2. Cathodic ·OH cleaves long-chain fats (e.g., stearic acid C₁₈H₃₆O₂) into small molecules (e.g., acetic acid C₂H₄O₂).
VOCs (Polar/Nonpolar)	1. Polar VOCs (formaldehyde, isopropanol): oxidized by Fe²⁺/Al³⁺. 2. Nonpolar VOCs (benzene, toluene): cathodic ·OH nonspecifically cleaves carbon chains, converting fully to CO₂ and H₂O.
Heavy Metals (Pb²⁺, Hg²⁺)	1. Cathodic electrodeposition. 2. Formation of metal hydroxide precipitates with anodic ions, achieving solid–liquid separation.

(4) Dual-Electrode Progressive Purification Process

Primary Multilayer Parallel Electrode Set: Rectifies vortex flow, suppressing turbulence; reduces pressure loss by >33%; prolongs pollutant retention time; initiates degradation of high-concentration pollutants (dust, oils).
Secondary Multilayer Parallel Electrode Set: Treats wastewater from exhaust scrubbing under reinforced electric field; further purifies residual micro-pollutants (undecomposed VOCs, fine oil mist) and processes wastewater simultaneously. Treated gas is redirected to the clean chamber for discharge in compliance with standards.
