VENTURI WET SCRUBBER

Overview

INTRODUCTION

Venturi Wet Scrubber

1- Structure and Operating Principles

Design:

Features a narrow section in the middle (Venturi throat) with wider openings at both ends. The absorbent solution is sprayed into the gas stream at the narrowest point.

Operating Principles:

• Exhaust gas is introduced at high velocity through the narrow section of the Venturi tube.
• The absorbent solution is sprayed directly into the high-speed gas stream.
• The intense collision between gas and liquid removes fine particles and pollutants from the gas stream.

Gas Flow Rate:

High, typically designed for treating exhaust gases with high velocities.

Efficiency:

Highly effective at removing fine dust particles and hazardous gases.

Advantages:

• Excellent efficiency in removing fine particles (e.g., PM2.5, PM10).
• Can handle high-velocity and high-concentration polluted gas streams.
• More compact size compared to the Spray Tower.

Disadvantages:

• Consumes more energy due to the need for high gas velocity.
• Higher investment and operating costs.
• Maintenance is more challenging due to the complexity of the design.

Applications:

• Treatment of exhaust gases from heavy industries, such as kilns, power plants, and cement production.
• Highly effective for gases containing ultrafine particles and SOx, NOx pollutants.
