Title: Improvements in liquid seals
IPC: B03C3/70
Filed: 1930-10-29
Abstract: <PICT:0363771/III/1> In order to maintain a constant level of liquid in a liquid seal for insulating conductors passing into a gas-filled chamber, such as an electrical precipitator, in which the insulating liquid is contained in a closed vessel, means are provided for equalizing the pressures prevailing in the space inside the vessel above the liquid and in the gas-filled chamber.  The pressure equalization may be effected by mechanical pressure regulators or by connecting the gas-filled chamber to the enclosed space above the liquid seal by tubes of small bore which may be partially filled with liquid.  The insulating liquid may be maintained at a temperature above the dew point of the gas undergoing treatment, or may be cooled by circulation, and the vessel containing the liquid may be formed with a jacket for cooling or heating purposes.  The Figure shows an electrical precipitator comprising a gas chamber 1 provided with electrodes 2 suspended from a support 3 and supplied with high-tension current through a lead-in insulator 8 carried by a dome-shaped casing 7 mounted on the gas chamber.  A gastight closure of the casing 7 is effected by a hood 5 which dips into an insulating fluid 4 contained in an annular space formed between the walls of the casing 7 and an internally projecting tube 6 carried on the lower end of the casing.  A pipe 9 connects the casing 7 to the clean gas space of the chamber 1. The insulating liquid 4 is circulated by a pump 11 through a cooling or tempering device 12.
