Patent number: 8956448Abstract: An environmentally-friendly exhaust device comprises an outer tank. An inner pipe is disposed inside the outer tank. An air propeller is disposed below the inner pipe inside the outer tank. An upper guiding plate and a lower guiding plate are disposed on a surface of the inner pipe for connecting with the outer tank. Thereby, air, oil mist and water are entered between the outer tank and the inner pipe; and are guided to the air propeller below through the upper and the lower guiding plates; and then are exhausted through the inner pipe upwardly. The purification of oil mist is processed integrally for enhancing the efficiency of exhaust and achieving the environmentally-friendly effects. Multiple layers of filter screens provided for carrying out multiple filtering are economically effective and can further enhance the environmentally-friendly effects.Type: GrantFiled: December 9, 2012Date of Patent: February 17, 2015Inventors: Chun-Rei Yang, Shih-Wei Lai

Patent number: 8377185Abstract: This invention is a dust removal system for dust gas which comprises at least an atomizer. The atomizer comprises an atomizing chamber and an atomizing mechanism; the atomizing chamber includes an inlet for the dust gas and an outlet for the gas after mixture; the atomizing mechanism comprises a water chamber, the first atomizing ball, the second atomizing ball, an umbrella-shaped atomizer, and a regulating mechanism; the water chamber includes the first and second water inlet and the first and second water outlet; the regulating mechanism adjusts the fit clearance between the first atomizing ball and the first water outlet, the fit clearance between the second atomizing ball and the second water outlet, and the flare angle of the umbrella surface of the umbrella-shaped atomizer. The beneficial effect is: the two-stage atomization—coordinating the atomizing balls and the water outlets, and using an umbrella-shaped atomizer—guarantees the atomizing effect.Type: GrantFiled: October 29, 2010Date of Patent: February 19, 2013Assignee: Shenzhen Sunxing Light Alloys Materials Co., Ltd.Inventors: Xuemin Chen, Qingdong Ye, Sihai Zhou

Patent number: 8017090Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.Type: GrantFiled: May 21, 2009Date of Patent: September 13, 2011Assignee: United Phosphorus Ltd.Inventors: Shroff Rajnikant Devidas, Pushpaksen P.

Patent number: 7381378Abstract: The invention is a flue gas scrubber for removing carbon dioxide from the emissions of coal fired furnaces by induced draft of said emissions into a scrubber barrel which is positioned within the facility smoke stack. The flue gases pass through electrically charged plates and enter said scrubber barrel tangentially through a connecting duct and pass upward and through a sorbent mist containing a dissolved salt that is generated as the diffused horizontal discharge from a plurality of longitudinally aligned ejectors. The sorbent liquid from the said ejectors containing the captured effluent carbon dioxide passes upward and coalesces on the cooling surfaces of a condenser positioned in a sonic resonant field and then passes downward into a sludge basin where it is further processed to remove particulate mater and to reclaim the scrubber water.Type: GrantFiled: March 9, 2005Date of Patent: June 3, 2008Inventor: Edward Milton McWhorter

Publication number: 20020078826Abstract: A cyclone separator, for the separation of particulate materials from a particle-bearing gas or vapor, in which the particle-bearing gas or vapor is injected into a separating chamber (10), and the particles centrifuged to a separating chamber wall (12) of the separating chamber (10) for collection, the separating chamber wall (12) being wetted by a liquid to assist in collection of the centrifuged particles from the separating chamber wall (12), the separating chamber wall (12) being at least partly porous, the separating chamber wall (12) being wetted by the passage of the liquid through the porous part, to provide a more uniform wetting of the separating chamber wall (12), and hence more efficient particulate collection than previously achieved by prior art methods. The cyclone separator of the invention may also be used for the separation and collection of gas or vapor-born vapors, in place of particulates.Type: ApplicationFiled: November 14, 2001Publication date: June 27, 2002Inventor: Peter John Day
