A tray assembly for improved gas/liquid contact in a chemical process tower includes a tray deck and a downcomer. A mixer is provided in the top of the downcomer and a distributor is attached to a floor of the downcomer. The mixer includes at least one mixing baffle parallel to an outlet weir on the tray. The distributor includes a plurality of spaced apart flow directing plates extending downwardly toward and spaced apart from the floor of the downcomer. In combination, the mixer and distributor effect even liquid flow across the surface of a subjacent tray deck.

The humidifier includes a humidification section which vaporizes water to produce humidified air, and a fan which produces in an air passage an air flow delivering the humidified air to the outside. The humidifier further includes a sterilized water producing section which produces sterilized water, an ultrasonic irradiator which produces sterilizing mist through ultrasonic irradiation of the sterilized water, an auxiliary passage through which the sterilizing mist is delivered to the outside, and an operation switching mechanism. The operation switching mechanism is switched between a first operation mode in which the air passage and the auxiliary passage communicate with each other to introduce the sterilizing mist into the air passage, and a second operation mode in which communication between the air passage and the auxiliary passage is blocked.

A selective catalytic reduction including a decomposition section including an intake chamber, with a swirl generating plate disposed in an internal volume of the intake chamber. The swirl generating plate includes a curved sidewall, a first end defining an opening, and a second end. The curved sidewall is oriented substantially normal to the direction of an intake flow of exhaust gas and a convex surface of the curved sidewall is oriented to face the direction of the intake flow. The swirl generating plate is configured to divide the intake flow into a first flow portion flowing through the opening, a second and a third flow portion which are directed substantially normal to the direction of intake flow and the flow direction of the first flow portion, and in opposite directions to each other towards a backwall of the intake chamber so as to create opposing swirls.

A diffuser is disclosed and includes a channel with an inner portion having an inlet and an outlet through which a gaseous substance enters and exits the diffuser, respectively. The inner portion includes a first conical section that has an increasing cross-sectional area, taken along a plane perpendicular to a central axis, in a first direction. The inner portion also includes a second conical section that has a decreasing cross-sectional area, taken along a plane perpendicular to the central axis, in the first direction. The second conical section is communicatively coupled with the first conical section. The outer portion includes a first annular section that has an increasing cross-sectional area, taken along a plane perpendicular to the central axis, in a second direction opposite the first direction. The diffuser further includes a plurality of orifices that communicatively couple the second conical section with the first annular section.

A steam dispersion apparatus includes a steam chamber communicating in an open-loop arrangement with a first steam source for supplying steam to the steam chamber. The steam chamber includes a steam dispersion location at which steam exits therefrom at generally atmospheric pressure. A heat exchanger communicates in a closed-loop arrangement with a second steam source for supplying steam to the heat exchanger at a pressure generally higher than atmospheric pressure. The heat exchanger is located at a location that is not directly exposed to the air to be humidified, the heat exchanger being in fluid communication with the steam chamber so as to contact condensate from the steam chamber. The heat exchanger converts condensate formed by the steam chamber back to steam when the condensate contacts the heat exchanger.

A high-gravity rotating bed device, including a motor, a rotor and a housing. The rotor and the motor are entirely arranged within the housing. A load-bearing plate is provided within the housing. The load-bearing plate divides the housing into a reaction chamber and a balance chamber. The motor is arranged within the balance chamber. A transmission shaft of the motor passes through the load-bearing plate and is fixedly connected to the rotor arranged within the reaction chamber. A gas inlet, a gas outlet, a liquid inlet and a liquid outlet are arranged on the housing. An externally communicating pipeline is arranged on the balance chamber. Also disclosed is an application of the present high-gravity rotating bed device under high-pressure conditions in operations such as mixing, transferring and reacting.

Disclosed herein is a self-cleaning evaporation type humidification apparatus. The self-cleaning humidification apparatus is a floating drop evaporation type humidification apparatus of a new concept using a super hydrophobic surface, which provides safe humidification and does not require maintenance and repair, such as cleaning, by naturally or forcedly evaporating floating drops through control of the floating drops in the super hydrophobic surface based on the self-cleaning function, virus reproduction inhibition function, and water-repellant function of the super hydrophobic surface.

Disclosed herein is a flocculation basin inclusion ion type water treatment apparatus using dissolved air floatation which includes: a flocculation basin which forms flocs by mixing a coagulant inserted into feed water and grows up the flocs; a contact zone to which fine bubbles are induced through a nozzle disposed at a lower part; and a separation zone which removes the flocs when the fine bubbles are attached to the flocs and the flocs float on the surface of water, the flocculation basin inclusion type water treatment apparatus including: a fine bubble forming part configured to separate a portion of the feed water at an upstream side of the flocculation basin by piping, configured to form saturated water using the separated portion of the feed water and configured to supply the saturated water to the nozzle.

The present invention concerns a nozzle for injecting pressurized water containing a dissolved gas, said nozzle comprising: a cylindrical intake chamber (20) for said water; a cylindrical expansion chamber (30) comprising a part (301) communicating with said intake chamber (20) by an orifice (401) and an outlet; a diffusion chamber (60) of truncated conical section communicating with the outlet of said expansion chamber (30) and widening out from said expansion chamber;
said nozzle comprising means for putting the stream of water that flows out of said expansion chamber (30) into rotation.

A cooling tower with a hot water distribution system includes a distribution lateral disposed above a hot water basin. The distribution lateral discharges fluid into the hot water basin, which in turn, releases the fluid through a plurality of orifices. As the fluid is released, it falls on heat-exchanging fill material that assists in increasing the cooling rate of the fluid. The distribution lateral is configured structurally to discharge the fluid through a plurality of outlets at one or more angles (as compared to the horizontal) into the hot water basins. In one embodiment, the outlets are arranged into one or more rows that extend along a substantial length of the distribution lateral. Discharging the fluid in this manner enhances and promotes a more even fluid flow within the hot water basin, which results in a more even fluid flow over and onto the fill material, thereby increasing thermal efficiency.
