High efficiency Chemical Exhaust Absorption System Wet Scrubber for acid and alkali waste gas washing tower

CZXD Series Exhaust Gas Purification Tower

The CZXD Series Exhaust Gas Purification Tower is designed for the wet absorption purification of exhaust gases. It plays a critical role in improving air quality by efficiently removing pollutants such as hydrogen chloride (HCl), sulfuric acid mist (H2SO4), and alkali fog (NaOH). The system has been thoroughly tested, demonstrating high purification efficiency, with an average purification efficiency of 96.3% for hydrogen chloride (HCl), 93.2% for sulfuric acid mist (H2SO4), and 95% for alkali fog (NaOH).

Key Features

High Purification Efficiency

• 96.3% purification efficiency for hydrogen chloride (HCl), 93.2% for sulfuric acid mist (H2SO4), and 95% for alkali fog (NaOH), ensuring effective environmental protection.

Reasonable Structural Design

• The wet absorption system uses a packing and spray packet classification design to ensure thorough purification. Exhaust gases pass through multiple stages of treatment, achieving uniform contact between the gas and liquid phases.

Effective Gas-Liquid Contact

• The system uses spray sections and filler layers that allow for full gas-liquid contact, enabling the purification process to be highly effective and efficient.

Suitable for Acidic and Basic Waste Gas

• The purification tower is adaptable to both acidic and basic exhaust gases. For acidic gases, sodium hydroxide (NaOH) is used as the absorption and neutralization liquid. For basic gases, neutral or acidic washing water is employed.

Exhaust Gas Treatment

• The exhaust gas is treated with liquid removal devices to remove fog before being safely discharged into the atmosphere, ensuring the emissions meet national environmental standards.

Specifications

Working Principle

Exhaust Gas Intake

• Exhaust gas is drawn into the purification tower by a fan, where it first enters the pressure chamber for uniform distribution.

Gas-Liquid Contact

• The gas moves through two layers of filler and is treated in two spray sections where gas and liquid phases come into full contact, allowing absorption reactions to occur.

Liquid Removal

• After absorption, the gas passes through a liquid-removal device that removes residual liquid before being released through the exhaust pipe into the atmosphere.

Emissions Compliance

• The treated exhaust gas is released after meeting the required environmental standards for clean air.

Applications

This exhaust gas purification tower is primarily used in industries where the purification of acidic or basic exhaust gases is critical, including chemical plants, manufacturing facilities, and other industrial settings. It ensures that emissions comply with national environmental regulations, providing a cleaner, healthier environment.
