Customizable Environmental Protection Equipment for Various Types of Industrial

Product Specification

Equipment Description:

I. Workflow

1. Exhaust Gas Capture: A hood collects exhaust gas and pipes it to a treatment system.
2. Primary Purification: A dry filter intercepts particulate matter, while a condenser cools the air (for high-temperature operation).
3. Oxidative Decomposition: Catalytic Combustion: A catalyst decomposes organic matter at high temperatures.
Photocatalysis/Plasma: Ultraviolet light or a high-voltage electric field oxidizes and degrades pollutants.
4. Standardized Emissions: Purified gas is monitored and discharged through a chimney after compliance with standards.

II. Technical Parameters

III. Equipment Advantages

High-Efficiency Purification: Catalytic combustion achieves a purification rate of ≥95% for high-concentration VOCs, while photocatalysis is suitable for low-concentration, complex exhaust gases.
Energy-Efficient Design: The catalytic combustion heat recovery system reduces energy consumption by over 30%.
Corrosion Resistance: Fiberglass and stainless steel materials withstand acidic, alkaline, and high-temperature environments.
Intelligent Control: Integrated online monitoring and automatic adjustment functions reduce manual intervention.

IV. Operation and Maintenance Key Points

Daily Maintenance: Clean carbon deposits on the catalyst surface quarterly and replace expired catalysts.
Monthly check the UV lamp brightness; replace lamps if they decrease by more than 30%.
Troubleshooting: Reduced purification efficiency: Check catalyst activity, UV intensity, or plasma electric field stability.
Blower Abnormality: Check for impeller corrosion or dust accumulation and calibrate the dynamic balance.

V. Application Scenarios

Electroplating Oxidation Tanks: Treat highly toxic exhaust gases such as cyanide and chromic acid mist.
Chemical Reactors: Degrade benzene and organic solvent volatiles.
Spray Paint Shops: Purify VOCs and paint mist particles.

Main structures and components:

I. Exhaust Gas Collection System
‌1. Gas Collection Hood

Use corrosion-resistant materials (such as 316L stainless steel or fiberglass) to cover the pollution source. A closed or side-suction design improves exhaust gas collection efficiency. The collection air velocity is typically 0.5-1.5 m/s.

For large-scale or open pollution sources, a multi-point gas collection hood system can be configured in parallel.
‌2. Exhaust Duct

Use fiberglass or PVC materials, with a diameter of 150-500 mm. Avoid right-angle bends to reduce air resistance. The duct interior should be smooth to prevent dust adhesion.

High-temperature exhaust ducts should be insulated (such as aluminum silicate fiber) to prevent heat loss and affect subsequent treatment efficiency.

II. Pretreatment Unit
‌1. Dry Filter

A pre-filter (pore size ≤ 2 mm) intercepts large dust particles and liquid droplets, protecting the downstream oxidation device.

In some scenarios, a cyclone dust collector can be added to increase dust filtration efficiency to ≥ 90%. 2. Condenser (Optional)
For high-humidity or high-temperature exhaust gases (≤150°C), heat exchange is used to cool the exhaust gas to 40-60°C, reducing its volume and recovering some organic matter.

III. Oxidation Purification Unit
1. Catalytic Combustion Unit (RCO)
Catalyst Layer: Precious metals (platinum, palladium) or metal oxide catalysts oxidize and decompose VOCs, aldehydes, and other organic matter. The reaction temperature is 250-400°C, with a purification efficiency of ≥95%.
Heat Exchange System: Ceramic regenerators or multi-tube heat exchangers recover combustion heat, achieving a heat recovery rate of ≥70%, reducing operating energy consumption. 2. Photocatalytic Oxidation Device
UV Photolysis Module: Emits 185-254nm ultraviolet light to activate a titanium dioxide (TiO₂) coating, breaking down organic matter into CO₂ and H₂O. Suitable for low-concentration, complex exhaust gases.
Reaction Chamber: Made of corrosion-resistant quartz glass or 316L stainless steel, with a light transmittance ≥80%.
3. Plasma Processor
This device uses high-voltage corona discharge to generate high-energy electrons and free radicals, degrading odorous gases (such as hydrogen sulfide) and difficult-to-degrade organic matter with a treatment efficiency ≥85%.
The electrode module is made of titanium alloy or ceramic and supports modular replacement to adapt to different operating conditions.

IV. Power and Monitoring System
1. High-Temperature-Resistant Fan
Made of fiberglass or alloy, it offers an air volume of 2000-50,000 m³/h and a pressure of 1200-2500 Pa, suitable for high-temperature and corrosive exhaust gases.
Equipped with a frequency converter to adjust the air volume to match equipment load fluctuations. 2. Monitoring and Control System
An integrated VOCs online detector and temperature sensor monitor emission concentrations and equipment operating status in real time, automatically issuing alarms and adjusting treatment parameters when standards are exceeded.
The chimney height must be ≥ 15 meters, complying with the "Comprehensive Emission Standard for Air Pollutants" (GB16297-1996).
