Disclosed is a filtration enhancement apparatus and an associated method. The apparatus includes a number of electromagnetic grids that are placed in series. The first grid conditions ambient particles to generate particles with both a positive and a negative charge. These charged particles are then delivered to a second and third grid wherein a low, medium, and/or high frequency alternating current is employed to force the positive and negative charged particles to collide and conglomerate with one another. The conglomerated particles are then sent into the ambient environment for subsequent filtration.

A nozzle spray head is provided for use in a dynamic electrostatic air filter, in which the nozzle spray head assembly exhibits multiple nozzle orifices as outlet ports, which extend from the bottom of the nozzle body such that the distances between the outlet ports and a target member are not constant. The charged multiple outlet ports exhibit a more uniform electric field at their tips, thereby enabling a better and more uniform spray pattern to be emitted by each of the individual outlet ports. In one embodiment, the outlet ports are grouped in concentric circles, in which the innermost circle comprises outlet ports of the greatest lengths, and the outermost circle comprises outlet ports of the smallest lengths.

An air purification system includes an electrostatic collection grid module inside the housing of the system to remove particulate matter from the air flowing through the housing. The collection grid module is removable from a side of the housing. The collection grid module is equipped with a handle and a release mechanism. A user may draw out the collection grid module from the housing by pulling the handle while activating the release mechanism. Thus, the collection grid module may be cleaned with ease.

The present invention relates to a method and apparatus for filtering and drying a product. In a preferred embodiment, the apparatus comprises a container having a plurality of porous walls and a plurality of solid walls that divide the container into a plurality of product chambers, a plurality of vacuum chambers, and, preferably, a plurality of heat transfer chambers. Each product chamber shares at least one porous wall with an adjacent vacuum chamber. Each product chamber preferably shares at least one solid wall with an adjacent heat transfer chamber. According to the method of the present invention, a product is introduced into the product chambers, where the product is held while a substance is filtered from the product through the porous walls and the product is dried by reducing the pressure in the vacuum chambers and the product chambers. In a preferred embodiment of the method, a heat transfer fluid flows through the heat transfer chambers to facilitate keeping the product frozen and/or to facilitate faster drying of the product.

The present teachings relate to a electrostatic precipitator having a plurality of electrostatic precipitation units positioned within the electrostatic precipitator. Each of the electrostatic precipitation units includes a plurality of negative wire electrodes and a plurality of positive electrode plates. The electrostatic precipitation units are arranged such that spacing between the negative wire electrodes of a first electrostatic precipitation unit is a first distance apart, and spacing between the negative wire electrodes of additional electrostatic precipitation units is at least less than the spacing between the negative wire electrodes of the first electrostatic precipitation unit. Moreover, a variable voltage is applied to the each of the electrostatic precipitation units between the positive electrode plates and the negative wire electrodes so as to cause particles in the exhaust gas to adhere to the positive electrode plates.

A gas separation apparatus using electrostatic precipitators and mechanical rappers is enhanced by the addition of an opposite polarity refreshing power supply and a switching arrangement. The switching components selectively disconnect the primary power supply and connect the refreshing power supply to the electrostatic precipitator, causing an electrical impulse in the precipitator sufficient to dislodge precipitate from the collector plates. In one embodiment, an RC filter is further provided to control the impulse and reduce the burden that would otherwise be placed upon the refreshing power supply. In a second embodiment, a pair of SCR strings serve as the switches. Cleaning power is delivered from a capacitor through one of the SCR strings using a resonant circuit, the resonance which causes the SCR string to commutate off after the impulse has been delivered. The capacitor is charged to a pre-calculated potential, dependent upon a measured potential just prior to delivery of the cleaning power, to ensure that the cleaning voltage stays below a corona onset voltage. The novel separation apparatus and technique offer particular synergy when applied to the effluent stream from a coal-fired electric power plant or other similar gas streams.

An air conditioning device for heating and/or an environment is provided. The air conditioning device includes a heat exchanging apparatus, a passage, and a corona discharge apparatus. The passage is in thermal communication the heat exchanging apparatus and extends between an inlet and an outlet. The corona discharge apparatus is disposed within the passage to draw a fluid from the environment into the passage through the inlet, move the fluid through the passage to permit the heat exchanger to remove or heat the fluid, and expel the fluid through the outlet into the environment. As such, the environment is cooled or heated. Embodiments of the present invention include package terminal air conditioners (PTACs), room air conditioners (RACs), and mini-split heating and cooling systems.

An air transporting-conditioning device comprising: a housing, an emitter electrode configured within the housing, a collector electrode configured within the housing and positioned downstream from the emitter electrode, a removable trailing electrode configured within the housing and downstream of the collector electrode, a first voltage source electrically coupled to the emitter electrode and the collector electrode, wherein the first voltage source energizes the emitter and collector electrodes to create a flow of air downstream from the emitter electrode to the collector electrode, and a second voltage source electrically coupled to the trailing electrode. The second voltage source is independently and selectively controllable of the first voltage source. The housing includes a grill, whereby the trailing electrode is removably secured to the grill. Alternatively, the trailing electrode is removable from the housing by other means or fixed in the housing.
