1. Equipment Overview

The Vertical Tower-Type Gas Cooler is a heat exchange device designed to reduce the temperature of high-temperature raw coke oven gas as it exits the coke oven (typically around 700°C to 800°C). This rapid cooling process prepares the gas for subsequent purification and enables partial tar condensation.

2. Working Principle

1. Gas Inlet
   Hot raw gas enters from the bottom of the tower and flows upward.

2. Spray Cooling
   Cooling water is sprayed from the top through multi-level nozzles. The gas and water interact in a counter-current manner, achieving efficient heat exchange and rapid gas cooling.

3. Tar Condensation
   As the gas temperature drops, tar vapors condense and are carried downward with the water stream.

4. Gas Outlet
   The cooled gas exits from the top of the tower and continues to the next purification unit, typically an electrostatic tar precipitator.

3. Structural Components

• Tower Body: Usually made of carbon steel or stainless steel with anti-corrosion lining.

• Spray System: Multi-layered nozzles ensure full contact between gas and water.

• Demister: Prevents water mist and tar droplets from entering downstream equipment.

• Drainage System: Periodically discharges tar-water mixture from the bottom.

• Access Platform & Ladder: For convenient inspection and maintenance.

4. Key Advantages

5. Application Scenarios

• Primary gas cooling systems in large- and medium-scale coke plants

• Pre-treatment of high-temperature gases in coal chemical plants

• Industrial cooling of gas streams with high tar content

• Projects with limited installation area requiring vertical designs

6. Selection Guidelines

7. Conclusion

The Vertical Tower-Type Gas Cooler offers a reliable and efficient solution for coke oven gas primary cooling. Its ability to rapidly reduce gas temperatures, facilitate tar recovery, and minimize footprint makes it an ideal component in modern gas treatment lines.
