Abstract: Apparatus and method for removing particulates and corrosive gases from a gas stream includes the serial use of a condensing wet electrostatic precipitator section for removing smaller particulates, in the submicron range, in conjunction with a vertically aligned preliminary scrubber section which removes larger particulates, in the micron range, and corrosive gases, in an integrated unit in which the temperature and moisture conditions in the gas stream are controlled for assuring effective and efficient operation of the condensing wet electrostatic precipitator section. Discharge electrodes of the electrostatic precipitator are supported by insulators which are protected against deleterious deposits of particulates by discharge electrode elements and collector electrode elements placed between the gas stream and the insulators.

Abstract: An improved electrostatic precipitator system is provided for use in high-grease atmospheres in which the grease is electrically conductive. The precipitator includes high-voltage insulators that are both located in areas unlikely to accumulate electrically-conductive grease and that, in themselves, can operate in a high-voltage system without tracking, even when a certain amount of conductive grease has accumulated on the insulators' surfaces. In a multi-cell precipitator system, a high-voltage insulator is provided as part of a cell-to-cell assembly that receives high-voltage electricity on one side of its insulator, and conducts that electricity to its opposite side, and is placed in a specially-shaped cut-out in the bulkhead between the cell chambers, in which the cut-out is shaped so as to minimize the amount of grease that may accumulate upon the cell-to-cell assembly's insulators. The electrostatic precipitator also includes a high-voltage electrical power supply that has special current limiting features and time delay functions that allow it to operate during relatively brief time intervals when a high-humidity atmosphere exists along with the electrically-conductive grease particulate. The electrostatic precipitator also includes electrical door interlocks using safety limit switches to detect whether or not any of the doors have been opened and which shut down the high voltage power of the system in the event of an untimely opening of one of the doors.

In a second aspect of the invention, a single valve and microcomputer are used in place of the pair of valves and in conjunction with the thermocouple regulate the flow through the main and by-pass flow paths and the regeneration of medium. In a third aspect, a compact enclosure is provided for installations where space is limited. An optional pre-converter, electrostatic precipitator, air injection and thermal stabilizer are disclsoed for enhancing performance and increasing the filtration efficiency of the device over a broad range of diesel engine applications.

Abstract: Lead-in device for passing a tension supply line or conductor through the cover of an electric filter down to its spray system, the tension supply line or conductor being concentrically surrounded by a duct arranged to run from the filter cover to the interior of the filter. The tension supply line or conductor is arranged to be surrounded by an insulator by positioning the said insulator above the filter cover so as to be spaced therefrom and so as to be radially spaced from the tension supply line or conductor, and an insulating bush is secured to the tension supply line or conductor at a position below the insulator. The insulating bush is arranged to be surrounded by a barrier disc so as to leave a barrier slit, and the space left above the barrier disc is occupied by a sealing gas maintained under overpressure with respect to the pressure prevailing inside the filter.
