Wet chemical filter


1 Wet single-stage chemical filter

EKOvent APOX1

Wet single-stage chemical filter
Basic sizes:
  • The dimensions of parts of this device are derived from the constructional dimensions of the spaces from which it is necessary to purify waste air, i.e., based on the required air flow rate.
Application:
  • These devices are installed in places where it is necessary to purify polluted air resulting from technological processes.
Design:
  • The wet chemical filter is standardly made in a vertical design from stainless steel and is suitable for both indoor and outdoor installation.
Operating principle:
  • The amount of solution in the wet filter is maintained via a level regulator. Gas treatment (washing) is carried out on the surface of special polypropylene filling. The fillings are washed via nozzles and a high-pressure pump, all with the help of a solution whose pH value is constantly measured and automatically adjusted as needed. Periodic discharge of the resulting sediment is done via a manual or automatic valve. The amount of sediment depends on the load and the filter's operating mode. The filter is equipped with all necessary equipment for 24-hour operation.
  • The filter is controlled via an electrical control cabinet. An additional tank for process chemical (alkali or acid, depending on the type of flushed gases) and automation for controlling the solution's pH value and dosing of process chemical are supplied with the filter. The filter must be connected to the water supply network and wastewater system. The fan is installed inside the filter at the top.

2 Wet two-stage chemical filter

Wet two-stage chemical filter
Basic sizes:
  • The dimensions of parts of this device are determined by the constructional dimensions of the spaces from which it is necessary to purify waste air, i.e., based on the required airflow rate.
Application:
  • These devices are installed in places where it is necessary to purify polluted air resulting from technological processes.
Design:
  • The wet chemical filter is standardly made in a vertical design from stainless steel and is suitable for both indoor and outdoor installation.
Operating principle:
  • The filter is two-stage, consisting of two reactors.
  • The polluted air first enters the acidic reactor, where nitrogenous alkaline compounds are removed. The second reactor is alkaline, where acidic sulfur compounds are removed.
  • The polluted air is washed in softened water to which appropriate alkaline or acidic chemicals are dosed.
  • The amount of solution in the wet filter is maintained via a level regulator. Gas treatment (washing) is carried out on the surface of special polypropylene filling. The fillings are washed via nozzles and a high-pressure pump, all with the help of a solution whose pH value is constantly measured and automatically adjusted as needed. Periodic discharge of the resulting sediment is done via a manual or automatic valve. The amount of sediment depends on the load and the filter's operating mode. The filter is equipped with all necessary equipment for 24-hour operation.
