Он Уловитель ионизации (also known as an Electrostatic Tar Precipitator or Wet Electrostatic Precipitator) is an advanced industrial air purification system engineered to capture sub-micron particulate matter, heavy tar, acid mists, and sticky aerosols. By utilizing ultra-high-voltage electrostatic ionization, it achieves a phenomenal collection efficiency of over 99.5%.

This system serves as a seamless, high-performance, and highly cost-effective direct replacement for premium European benchmark models, such as those manufactured by Lurgi или Dürr Megtec. It delivers equivalent or superior tar recovery rates and operational stability at a fraction of the capital expenditure (CapEx).

The Core Concept

When industrial smoke containing impurities such as tar, aerosols, and microscopic droplets passes through the intense high-voltage electric field of the catcher, a massive ionization of the carrier gas occurs. The impurities collide with and adsorb negative ions and free electrons, a process known as the charging phenomenon.

Under the direct action of the electric field's Coulomb force, these newly charged impurities are aggressively pulled toward the grounded precipitation electrode (anode tube). Upon contact, they release their charged particles and adhere to the electrode wall.

As the mass of the accumulated tar or impurities increases beyond its natural adhesion force, gravity takes over. The liquid wastes automatically flow down the tube walls and are discharged from the bottom hopper, while thoroughly purified clean gas exits from the top of the tower.

♻ High-Value Resource Recovery

Successfully separates and recovers pure, unadulterated tar and chemical oils without secondary wastewater. The economic value of recovered byproducts often pays back the equipment cost within 12 to 18 months.

💀 RTO & Downstream Protection

Acts as an impenetrable barrier against sticky resins and pitch. By installing it upstream, you prevent catastrophic clogging and thermal damage to Регенеративные термические окислители (РТО) and expensive ID fans.

⚙ Ultra-Low Pressure Drop

Unlike baghouses or venturi scrubbers that strangle airflow, our open-tube electrostatic design guarantees an operating resistance of less than 300 Pa, slashing your main fan's electrical OpEx.

⚡ Smart Spark & Arc Control

Powered by a high-frequency smart silicon rectifier, the system detects micro-sparks instantly, automatically suppressing arcs to maintain the highest possible corona voltage safely.

🔍 Sub-Micron Precision

Mechanical filters fail against ultra-fine aerosols. The Coulomb force effortlessly captures particles down to 0.01 microns, easily achieving strict modern opacity and plume eradication standards.

A robust infrastructure is critical for handling highly corrosive and volatile industrial exhaust. Our structural engineering focuses on longevity, safety, and uninterrupted operation.

• Corona System

  Comprises corona wires, high-voltage porcelain insulators, suspension rods, upper/lower rings, and tensioning weights. Positioned meticulously inside the tower to maintain perfect concentricity with the anode tubes, preventing short-circuits.

• Insulator Box with Thermal Control

  Features a specialized thermostatic box equipped with automated electric heating devices. This prevents condensation from forming on the high-voltage insulators, entirely eliminating the risk of electrical creepage and flashovers in high-humidity environments.

• Premium Material Selection

  Depending on your chemical stream, anode arrays are fabricated from robust Carbon Steel, highly corrosion-resistant 304/316L Stainless Steel, 2205 Duplex Stainless, or specialized Conductive Fiberglass Reinforced Plastic (FRP). This ensures decades of operational life.

• Heavy-Duty Housing & Drives

  Tower casings are robotically welded to ensure absolute gas-tight sealing for explosive environments. We also utilize precision industrial drive components for automated bottom scraping and discharge mechanisms where thick sludge handling is required.

⚙ Dedicated Control & Instrumentation

Our company provides a complete set of electric control equipment and precision instruments. The HV Control Cabinet acts as the central brain, dynamically adjusting voltage input/output based on real-time exhaust resistance. It features automated fault alarms, rapid cut-off relays for explosive gas safety, and seamless integration with your DCS/SCADA systems.

Q1: How much power does the Ionization Catcher consume?

Despite utilizing tens of thousands of volts, the system operates at very low current (milliamps). Combined with an ultra-low pressure drop (<300 Pa) that saves immense fan power, the overall system is remarkably energy efficient. Standard models draw between 15 KW to 42 KW depending on the gas volume.

Q2: Can it safely handle flammable coal gas?

Yes. The system is equipped with continuous oxygen analyzers, explosion-proof vents, and an intelligent spark-suppression rectifier that cuts power in milliseconds if O2 levels rise, ensuring absolute safety in coking gas applications.

Q3: Will the anode tubes clog over time?

No. We design the gas flow and tube spacing based on the viscosity of your specific pollutant. For highly viscous substances like asphalt smoke, automated hot ammonia water or steam flushing systems are integrated to keep tubes permanently clean.

Q4: Is this equipment suitable as a pre-filter for an RTO?

Absolutely. It is the gold standard for protecting Regenerative Thermal Oxidizers. By removing sticky aerosols and VOC-laden droplets upstream, it prevents the RTO's ceramic heat exchange beds from blinding or catching fire.

Q5: How does it compare to a traditional baghouse filter?

Baghouses are excellent for dry dust but fail completely when handling high-humidity, sticky, or tar-laden streams (resulting in "bag blinding"). The Ionization Catcher uses a non-barrier electrostatic method, making it immune to clogging while handling wet/sticky fumes.

Q6: What materials are used for the collection electrodes?

We match the metallurgy to your exhaust chemistry. Options include standard Carbon Steel, 304/316L Stainless Steel, highly durable 2205 Duplex Stainless Steel, and even Conductive Fiberglass (FRP) for severely acidic environments.

Q7: Do you provide installation services?

As a comprehensive EPC supplier, we provide full layout drawings, fabrication, shipping, and can dispatch seasoned field engineers to guide your local team through structural erection, high-voltage wiring, and final commissioning.

Q8: Does the system generate secondary wastewater?

Unlike wet scrubbers that transfer air pollution into massive volumes of water pollution, the Ionization Catcher precipitates the pure pollutant (e.g., liquid tar or oil), allowing for direct resource recovery with zero secondary wastewater generation.

Q9: What is the lifespan of the corona wires?

Manufactured from high-tensile, corrosion-resistant alloys, the corona wires (cathode) are designed for years of continuous operation without breaking, provided the internal tensioning weights and alignment are properly maintained.

Q10: How do I select the right size for my plant?

Simply provide our engineers with your actual gas volume (m³/h), operating temperature, and inlet pollutant concentration. We will calculate the exact Specific Collection Area (SCA) required and provide a tailored CAD proposal.
