High-Performance Environmental Protection Equipment for Acid Mist and Cyanide Treatment in the Electroplating Industry

Equipment Description

I. Workflow

Exhaust Gas Collection: Exhaust gas sources (such as electroplating tanks and pickling tanks) are captured using a locally enclosed gas collection hood or an external suction hood.
Pretreatment: Dry filters intercept large particulate matter and oil mist to protect downstream equipment.
Multi-stage Purification: Acidic exhaust gas enters a spray tower for neutralization and treatment; organic waste gas/cyanide is degraded through activated carbon adsorption.
Emission Compliance: Purified gas is tested and found to comply with the "Comprehensive Emission Standard for Air Pollutants" (GB16297-1996) and is discharged through a chimney.

II. Technical Parameters

Parameters	Specifications
Airflow	1000-100,000 m³/h (customizable)
Applicable Exhaust Gas Type	Acid mist (nitric acid, sulfuric acid, hydrofluoric acid), cyanide, VOCs, heavy metal vapors
Corrosion Resistance	Withstands strong acid and alkaline environments with a pH of 1-14
Operating Temperature	≤80°C (high-temperature exhaust gas requires pre-cooling)

III. Application Scenarios

Electroplating Industry: Treatment of acid mist and cyanide from processes such as pickling and chrome plating.
Electronics/Semiconductor Manufacturing: Purification of hydrofluoric acid mist and organic solvent exhaust from etching and cleaning.
Chemical/Pharmaceutical Industry: Treatment of VOCs and acidic and alkaline gases emitted from reactors and storage tanks.

IV. Equipment Advantages

1. High-Efficiency Purification: Multi-stage treatment units connected in series adapt to complex exhaust gas compositions, achieving an overall purification rate of ≥90%.
2. Corrosion-Resistant Design: Fiberglass, stainless steel, and Teflon coating withstand highly corrosive media such as hydrofluoric acid and concentrated sulfuric acid.
3. Low-Energy Operation: The circulating water system reduces chemical consumption, and automated control reduces manual intervention costs.
4. Modular Expansion: Flexible configuration of spray towers, adsorption towers, and other units is supported to meet diverse operating requirements.

V. Key Operation and Maintenance Points

1. Daily Maintenance: Monitor the pH value of the spray liquid (recommended 8-10) and regularly replenish NaOH solution; clean the filter and check for nozzle blockage monthly; and replace the activated carbon and packing layer every six months.
2. Troubleshooting: Abnormal fan vibration: Check for impeller corrosion or dust accumulation, and replace the balancing weight promptly. Decreased purification efficiency: Check the spray liquid concentration, activated carbon saturation, or packing blockage.

Main Structures and Components

I. Core Components

1. Impeller
- Function: The core compression component, responsible for gas compression and transport, is made of corrosion-resistant metal (such as stainless steel, copper) or coated materials. The blade shape directly affects airflow and efficiency.
- Design: Available in forward-curved, backward-inclined, arc-shaped, and linear types. Static and dynamic balancing are required to ensure smooth operation.
2. Motor
- An AC asynchronous motor or DC motor, with power customized based on the airflow (1.5-75kW), drives the impeller.
3. Air Inlet/Outlet
- Air Inlet: Equipped with a filter (expanded mesh stainless steel or aluminum) to intercept large particles (such as metal dust and liquid droplets) and reduce equipment wear.
- Air Outlet: Optimize airflow guidance design to reduce exhaust resistance and ensure compliance with environmental standards.
4. Fan Case
- The outer casing is made of welded steel plates or fiberglass reinforced plastic (FRP), integrating the impeller and deflector. It must be highly leak-tight and corrosion-resistant.
5. Bearings and Drive Unit
- Bearings: Support the rotation of the impeller and are typically made of rolling bearings or corrosion-resistant sliding bearings.
- Drive Unit: Includes the main shaft, couplings, pulleys, etc. Lubricant (such as L-AN32) is used to ensure smooth operation.

II. Auxiliary Structures

1. Air Guide
- Directs airflow evenly into the impeller, improving airflow utilization. The material must be corrosion-resistant (such as stainless steel coating).
2. Bracket
- Supports the overall fan structure and must possess high strength and vibration resistance to prevent imbalance during operation.
3. Circulation System
- When used in conjunction with a spray tower or activated carbon adsorption tower, an acid- and alkali-resistant circulation pump and piping are required to achieve multi-stage exhaust gas purification.

III. Differentiated Design and Materials

1. Corrosion-Resistant Material Selection
- For strong acid (such as hydrochloric acid and sulfuric acid) and strong alkaline exhaust gases, 316L stainless steel, fiberglass reinforced plastic (FRP), or Teflon coating are preferred.
- For high-temperature exhaust gases (≤200°C), high-temperature alloy materials are required.
2. Layout Compatibility
- Horizontal Fans: Suitable for high-volume applications (>50,000 m³/h), such as centralized exhaust systems.
- Vertical Fans: Compact design, suitable for combined systems (such as those located after a spray tower).

IV. Typical Applications and Operation and Maintenance

1. Application Scenarios
- Acidic Waste Gas: Combined with an alkaline spray tower for neutralization treatment, achieving a purification efficiency of ≥90%.
- Organic Waste Gas: Combined with activated carbon adsorption or photocatalytic oxidation equipment to improve VOC removal rates.
2. Operation and Maintenance Key Points
- Regular Cleaning: Check for impeller fouling and filter clogs every 1-3 months.
- Explosion-Proof Design: When handling flammable gases, an explosion-proof motor and emergency discharge valve are required.
