Abstract

933,286. Electrostatic precipitation. LODGECOTTRELL Ltd. March 15, 1962 [March 23, 1961], No. 6720/61. Class 117. A method of preventing reverse ionization from the collector plates of an electro-precipi. tator comprises the steps of causing a gas-borne dispersion of anhydrous sulphur trioxide gas to mingle with a stream of gas-borne particles flowing to the collecting chamber of the precipitator, and regulating the volume of anhydrous sulphur trioxide in the gas-borne dispersion to prevent formation of sulphuric acid. In the embodiment shown in Fig. 1, liquid sulphur trioxide is fed through a conduit 11 to a pressure vessel 12 to a level 15 shown in a sight glass 14. The vessel is heated electrically to regulate the volume of sulphur trioxide vapour which passes up a conduit 17 to a cross-header pipe 18 with branches 19 leading into a flue 20 which carries the gases to the precipitator (not shown). Air is admitted to the conduit 17 through a conduit 21 in turn fed from a conduit 24 by way of a chamber 22 with a heater element 23. Valves 26, 27 are provided to control the flow in the conduit 17 and samples may be taken through a valve 28. The embodiment shown in Fig. 2 is for continuous operation, having two reservoirs 30a, 30b which are alternately drawn upon whilst the other is refilled. The reservoirs contain liquid sulphur trioxide, which passes through a flowmeter 32 to a weir-type feeder 33 having a vertical conduit 34 with a serrated upper end 37, so that the sulphur trioxide flows down the conduit 34 and is heated by a heater 36 before passing into a cone 35 heated by a heater 38. The sulphur trioxide is vaporized and passes to the flue 20 as before. An inert gas, e.g. nitrogen, may be supplied in place of air to the conduit 24.
