ABSTRACT:
The disclosed treatment is for the removal of hydrogen halide constituents of an exhaust gas by means of a dry scrubbing agent to which the gas binds. The agent is sprayed into the gas in finely divided form just prior to flow of the gas through a register located at the entrance to a filter chamber. The agent is thus distributed evenly over the input of the filter and performs its binding function primarily while on the filter. The agent may be sprayed as a finely divided solid or as a fluid which rapidly dries to leave a coating of finely divided agent on the filter.
Also disclosed is an apparatus for practicing the method, including a nozzle casing with a plurality of spray nozzles located in the gas passageway at the input side of a register at the entrance to the filter chamber housing an electrical filter. The filter elements of the filter are so designed that the gas passageways between them force the gas to make periodic, sudden changes in direction which lead to a pulsation and a resulting gas turbulence. The turbulence improves the action of the agent on the gases.
