Standardkessel - Spray Cooler

As a result of the continuous supply of liquid, the phase interface between gas and liquid is constantly renewed. The intensive contact causes a washing, absorption or condensation effect and, thus, a mass transfer between gas and liquid. The exhaust gas cools down to condensation temperature, the pollutants and solvents contained in the exhaust gas condense to saturation conditions. The condensate mixes with the supplied liquid and is collected together with the spray jet in the apparatus sump. The liquid is drained off via a level control and the purified gas stream is discharged via a specially designed demister.

If required, the condensation unit can also be designed for operation on discontinuous processes (batch operations) and in the event of fluctuations in the exhaust gas volume. The technology is often used as a pre-separator or quencher for highly loaded or very warm exhaust gas streams as a preliminary stage of further cleaning processes and is also applicable for use in closed exhaust gas systems (e.g. of a dryer or coating system).
