    摘要: Apparatus and a method for electrically sweeping particles from a gaseous effluent are disclosed which are particularly efficient in removing small as well as large particles. A voltage is applied across two electrodes in such a way that a strong electric field can be generated between them. A source of ions is provided by bombardment of the effluent gas stream with electrons. A strong electric field established between the electrodes creates at least one region of ions having only one polarity and moves these ions towards the oppositely charged electrode. In the region having ions of one sign, these ions rapidly charge the particles, especially small sized particles because of the strong electric field. The charged particles are moved by the field and deposited on the oppositely charged collection electrode where they agglomerate in preparation for collection and disposal.

    摘要: An electronic air cleaner, in which an air inlet, a mechanical prefilter, an electrifying cell, an electrostatic collector cell, a chemical filter and an air outlet are arranged in the order in a casing of insulating material. The electrifying cell comprises a grounded conductive protection net located behind the mechanical prefilter, a plurality of thin-wire electrodes and a plurality of grounded conductive plates. The thin-wire electrodes are less than 50 microns in diameter and arranged in appropriate intervals at substantial rectangles with an air path from the air inlet to the air outlet. Each of the grounded conductive plates has one end attached to the protection net and backwardly extending between adjacent two of the thin-wire electrodes along the air path. The electrostatic collector cell comprises the entending parts of the grounded conductive plates and a plurality of negative high voltage conductive plates respectively connected to the thin-wire electrodes and laid between the grounded conductive plates. A direct current voltage less than 4.2 kilo-volts is applied to the negative high voltage conductive plates. An electric fan causes a flow of air from the inlet to the outlet to perform highly effective air cleaning under preventing the ozone development.

    摘要: The present invention relates to a system and process for controlling air pollution and basically relates to a photochemical method of removing contaminant compounds, such as sulfur dioxide and nitrogen oxides, from polluted effluent gas systems. Such contaminant compounds are first formed into complexes (such as an electron donor-acceptor molecular complexes) and clusters. After the contaminant compounds become associated with these complexes and clusters, ultraviolet light is introduced into the system resulting in the complexes or clusters being photooxidized. The photooxidization of the complexes or clusters generally tends to internally rearrange the complexes or clusters and to form non-volatile acid products that readily condense on available nuclei. The acid-like products resulting from the photooxidization treatment of the complexes or clusters can be removed from the gas system by conventonal particulate removal techniques.

    摘要: A wet electrostatic precipitator including at least one annular gas passage defined by concentrically arranged collector tubes have liquid distributors mounted thereabove to produce downwardly-flowing uniform liquid films on the walls of the passage. A discharge electrode structure is disposed in the annular passage, a high voltage being applied between the electrode structure and the liquid films on the collector walls to create an electrostatic field causing ionized particulates in a gaseous stream conveyed upwardly through the passage to migrate toward the films to be carried downwardly thereby for disposal. Incoming contaminated gas at high velocity is fed into a reagent chamber communicating with a Venturi inlet leading to the annular gas passage, the chamber containing one or more manifold rings provided with an array of jet nozzles for spraying a reagent into the chamber and Venturi inlet to intermingle and react with chemical contaminants in the inflowing gas to produce reaction products in particulate form which are precipitable in the passage. The axial positions of the rings within the reaction chamber relative to the Venturi inlet are adjustable in order to optimize the reaction with the gaseous or chemical contaminants in the incoming stream. In addition, a ring of catalytic material may be included in the reaction chamber to enhance the chemical interation.

    摘要: An improved electrostatic precipitator device capable of significant size reduction having flat parallel plates consisting of an ionizing corona discharge portion as a unitary structure which is utilized to effectuate precipitation of entrained particles from an air stream onto the surface of a plurality of associated collection members, as an air stream containing entrained particles is cleaned in passing through the precipitator device. The ionizer discharge portion of the unitary structure comprises a plurality of substantially uniformly spaced apart sharp electrical conductive protrusions directed to alternate sides of the unitary structure; thereby forming a uniform ionization region with a parallel portion of the collector extending the full length of the ionizer. The remainder of each of the unitary structure functions as a passive electrode which cooperates with the remaining portion of the collector to form highly concentrated electrostatic fields therebetween for enhanced collection efficiency with minimum re-entrainment of the particles to be collected.

    摘要: AN ELECTROSTATIC AIR FILTERING UNIT IS ADAPTED TO BE USED IN AN AIR FILTER. THE MODULAR STRUCTURAL CELL HAS AN OUTER PRE-FILTER PANEL, AN INNER PARTICLE COLLECTOR AREA AND AN IONIZER AREA THEREBETWEEN. ALTERNATELY CHARGEABLE AND GROUNDABLE PLATE MEMBERS IN THE PARTICLE COLLECTOR AREA FORM PASSAGEWAYS FOR AIR TO BE FILTERED, AND COLLECT CHARGED PARTICLES IN THE AIR DURING OPERATION. CHARGEABLE FILAMENTS ARE IN THE IONIZER AREA, AND DURING OPERATION CHARGE THE PARTICLES TO BE REMOVED FROM THE AIR AS THEY PASS THROUGH THE IONIZER AREA. THE PRE-FILTER PANEL IS EASILY REMOVABLY MOUNTED IN AN ENCLOSURE AROUNG THE IONIZER AREA, AND HELD IN MOUNTED POSITION BY RESILIENT MEANS WITH THE ENCLOSURE AND MOUNTING PERMITTING THE PANEL TO BE REMOVED FOR MAINTAINING THE MODULAR CELL.
