KVK-FUME EXTRACTION<br />

Advantages:<br />

● Operation without wastewater<br />

● Savings on fresh acid through return of<br />

scrubbed-out acid into the process<br />

● No additional chemicals<br />

● Exact determination of acid concentration in<br />

the scrubbing liquid through measurement<br />

of electrical conductivity<br />

● Automatic level control and fresh water feed<br />

● Use of high-quality corrosion-resistant radial<br />

fans and pumps<br />

PLANTS<br />

● Complete plant control system and<br />

visualization (soft PLC)<br />

KVK fume extraction for use in encapsulated<br />

pre-treatment plants and on<br />

lateral tank walls for:<br />

● hot-dip galvanizing plants<br />

● pipe pickling plants<br />

● stainless steel pickling plants<br />

KVK fume extraction plants include:<br />

● exhaust air scrubber<br />

● fan<br />

● pipework<br />

● exhaust and inlet air units<br />

● chimney<br />

● level controllers for returning water into the scrubbing circuit<br />

- all components made of corrosion – resistant material guaranteed by<br />

25 years of experience.<br />

Scrubbing the exhaust air prevents the release of aggressive and<br />

harmful vapors into the environment.<br />

Vapors and gases are absorbed in the scrubbing liquid and returned to<br />

the circuit.<br />

The most important basis for calculations are the determination of the<br />

exhaust air volume and the dependence of the flue gas burden on the<br />

operating conditions in the pre-treatment plant. All these calculations<br />

are performed by program modules developed by KÖRNER.<br />

Effective scrubbing and guaranteed compliance with emission limits<br />

can only be achieved through an individually designed fume extraction<br />

plant optimized on the particular application.<br />

KVK fume extraction plants can be used not only in encapsulated pretreatment<br />

plants but also for lateral suction channels on pickling tanks.<br />

KÖRNER supplies a range of different plants designed for HCl, H 2SO 4,<br />

HF, HNO 3 and mixed acids.<br />
