Counter Flow fume scrubbers are designed for
contaminants, which are difficult to absorb for all airflow requirements.
The Counter Flow design offers advantages in the efficient and effective use
of scrubbing solutions, as well as in a higher separator efficiency,
especially for deep beds of packing. High removal efficiency is advantageous
where the contaminants are highly offensive or have recovery value. In this
design mist and separating solutions carry-over at high gas velocity is
minimized by the use of dry packed bed mist eliminators.
Counter Flow separators are available with a variety of tower internals;
each designed to achieve a maximum in efficiency at a minimum of cost. The
separators are available with packed beds in height ranging from 1.2 metres
to 6.0 metres. The choice between B and C Series separators must be based
upon headroom required separating efficiency and future exhaust
requirements. Series B separator internals may be modified so as to achieve
separating efficiency equal to Series C separator.
Standard fume separators are packed with 50mm plastic tower fill, eg
tellerettes give a higher target efficiency with mist and light dust
problems.
