Abstract: A flue gas desulfurization apparatus includes an absorption tower that absorbs sulfur oxide in a flue gas, and drift suppression members that are arranged near a bend portion of a purified gas exhaust passage arranged at an outlet portion of the absorption tower, the drift suppression members serving to collect mist particles.

Abstract: A grease water separation apparatus includes an air chamber in communication with an indoor grill; a water scattering member comprising a space in communication with the air chamber, at least one sprinkling duct, and a pump in communication with the sprinkling duct; a heat exchanger connected to the water scattering member and comprising a grease filter and grease holes; a liquid collector connected to the heat exchanger and comprising a water reservoir in communication with the pump, a grease reservoir for collecting grease from the grease holes, and a grease water mixing reservoir; a water-grease separator connected to the heat exchanger and being in communication therewith, the water-grease separator comprising a hollow cylinder having an air outlet and an inlet within the water-grease separator, and a water-grease outlet for flowing water and grease to the grease water mixing reservoir; a centrifugal fan; and an air filter.

Abstract: The invention relates to a gas-water separator and particularly to a gas-water separator used in a washer wherein a plurality of inversed hooks are essentially provided on a surface of a baffle plate facing the air flow so that the water containing impurities can be collected on said inversed hooks and fall down to the bottom smoothly when said water containing impurities is entering into said gas-water separator. As a result, the water content carried by the exhaust air can be greatly reduced, even only dry air being exhausted. Thus, the present invention not only can improve the filtering effectiveness but also can be more environment-philic.

Abstract: An improved vacuum cleaner apparatus having at least three stages of dust collection with a path partially submerged in water and provided with a separation labyrinth. The apparatus is subdivided into two parts, an upper one which includes the support body of a suction motor unit, and a lower one which includes the labyrinth. The lower one provides an intermediate washable filter. The support body is housed in an opening coated by an acoustic insulating material.
