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

Gas Inlet
Hot raw gas enters from the bottom of the tower and flows upward.
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.
Tar Condensation
As the gas temperature drops, tar vapors condense and are carried downward with the water stream.
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.
