An air filtration system includable in and for HVAC equipment includes one or more intense field dielectric filter units and a field charging unit retained in a support structure or cabinet by a removable door which includes control circuitry and contactors engageable with corresponding contact members on a filter unit and the field charging unit for supplying high voltage DC potential to the respective units. Each filter unit includes a filter core comprising a stacked array of filter elements formed of dielectric sheets interconnected by elongated spaced apart ribs forming flow passages. The field charging unit and the filter units are removable from the support or cabinet for cleaning or replacement by opening or removing the door. An interlock switch and a field shorting mechanism are actuated during servicing or replacement of the system components.

An air filter for the removal of dust comprises two outside frames (1,2) supporting metallic screens (3,4), a centre frame (14) supporting an inside screen (13), a high voltage supply box (5), and removable fibrous pads (16). The outside frames (1,2) comprise hollow members held together by fitting rigid right angled corner members therein.
摘要:
A system for eliminating electrically conductive particles by detecting and destroying electrically conductive particles in a medium circulation. Electrodes are arranged by a power supply in potentials differing from each other, whereby electrically conductive particles getting drifted in connection therewith are arranged to be detected and destroyed by causing a shortcut between the electrodes. A device having a uniform frame. Inside the device there is a flow space for a flow-through of a medium circulation occurring inside thereof in its longitudinal direction. The flow space has, when viewed in a crosswise plane perpendicular to its longitudinal direction, adjacent narrow flow ways in one or more directions. Opposite walls of the flow ways are arranged as electrodes in potentials differing from each other.

The present technique is a wet electrostatic precipitator (ESP; 100) for removing particulates (2) from a gas (1) to produce a clean gas (6) on a clean gas side (105) of the wet ESP (100). The gas (1) flows through a duct (30) of the wet ESP (100) in a flow direction (8) substantially horizontally from an inlet (10) to an outlet (20) of the wet ESP (100). The duct (30) comprises an ionization zone (40) for receiving the gas (1) from the inlet (10), at least one discharge electrode assembly (50) extending into the ionization zone (40), and a precipitation zone (80) downstream of the ionization zone (40) and fluidly connected to the ionization zone (40). The precipitation zone (80) includes at least one precipitation electrode assembly (82). The discharge electrode assembly (50) is suspended from the clean gas side (105) towards the ionization zone (40) such that a discharge electrode (52) of the discharge electrode assembly (50) for generating a corona discharge inside the duct (30)is positioned inside the duct (30).

The invention relates to an electrostatic filter system comprising a supervision device for detecting punctures on the filter. The punctures have the same effect as short-circuits in a capacitor and would overcharge components in the electric power supply. The central supervision circuit detects such punctures and avoids an overcharge by way of a corresponding adjustment.
摘要:
Procedure and apparatus for the purification of air, flue gases or equivalent, in which procedure the air, flue gases or equivalent are directed into a duct or equivalent, in which procedure the air, flue gases or equivalent are ionized, and in which procedure the charged impurity particles (7) present in the air, flue gases or equivalent are attracted by one or more collector surfaces (2) by virtue of a difference in the states of charge, causing the particles to settle on said surface. The air, flue gases or equivalent are ionized by means of one or more ionizing electrodes (5) directed at a collector surface. The distance between the ionizing electrode or equivalent and the collector surface as well as the difference between the states of electric charge of the collector surface and the charged impurity particles are so adjusted that the impurity particles will be carried by an ion beam essentially directly towards the collector surface and settle on it.
