| 20110139004 | SPRAY DRYER ABSORPTION PROCESS FOR FLUE GAS WITH ENTRAINED COARSE PARTICLES - Disclosed herein is a method for reducing the amount of coarser particles from a stream of flue gas prior to treatment by a spray dryer absorption process (SDA). The method comprises the steps of directing a stream of flue gas containing entrained particles of varying sizes through a curve, thereby subjecting the particles to a centrifugal effect, collecting the particles predominately of the coarser size at a particles collecting means provided in the outer circumference of the curve, dispersing the flue gas reduced in particles of coarse particle sizes into the chamber of a spray dryer absorption apparatus, wherein the particles content of the original flue gas stream is above 20 g/Nm | 06-16-2011 |
| 20110139005 | Air Purifier Employing A Water Jet-Type Fan System, and Purification Method Thereof - The present invention relates to an air purifier employing a water jet-type fan system having a simple structure, in which water is pumped by a water pump and sprayed and scattered by the water jet-type fan system in which a plurality of spray nozzles are mounted on a fan having a flow channel, in order to purify contaminants. The fan system rotates by the principle of action and reaction using the spraying force of water. The air purifier of the present invention performs an air purification process and an air circulation function at the same time by spraying and scattering water so as to use the adsorption power of water, instead of using a motor fan for circulating air. The present invention also relates to a purification method of the air purifier. | 06-16-2011 |
| 20130206007 | DESANDING APPARATUS AND SYSTEM - A desanding system has an elongated vessel that is tilted at a non-zero inclination angle. A fluid inlet at the vessel's upper end discharges a gas stream having entrained liquids and particulates and a fluid outlet into a freeboard portion formed adjacent an upper portion of the vessel above a gas/liquid interface formed below the fluid outlet. A belly storage portion is formed below the interface. The freeboard portion of the vessel has a freeboard cross-sectional area that diminishes along the interface from the fluid inlet to a fluid outlet spaced away from and lower than the fluid inlet. The cross-sectional are of the freeboard portion causes precipitation of the entrained liquids and particulates therefrom and collect in the belly portion of the vessel. A desanded gas stream, being free of a substantial portion of the particulates is removed from the vessel through the fluid outlet. | 08-15-2013 |
| 20130213231 | FLUE GAS SCRUBBING APPARATUS AND METHODS THEREOF - An improved flue gas scrubbing apparatus and method are disclosed. The flue gas scrubber comprises a double-pipe or a two-pipe system whereby flue gas enters the system. Scrubbing is accomplished by interaction between the flue gas and base in a pre-injection zone, followed by further reaction in a primary injection zone and passage through a cyclone unit. In preferred embodiments of the invention, it comprises a bypass system by which flue gas is automatically exhausted directly to the atmosphere in case of a system failure. The gas exhausted from the apparatus following scrubbing meets or exceeds international emissions standards. | 08-22-2013 |
| 20140053731 | SYSTEMS AND METHODS FOR REMOVING PARTICULATE MATTER FROM A GAS STREAM - Horizontal duct scrubbing systems for removing particulate matter from a gas are disclosed. The horizontal scrubbing systems may receive a particulate-containing gas stream (e.g., containing PM10 and/or PM2.5 particulate matter), and remove at least some of such particulates by spraying liquid droplets co-current to the flow of the gas stream, where the liquid droplets have a volume median droplet diameter (DV0.5) of from 240 microns to 600 microns. The scrubbing system may be substantially free of flow deflection members between a liquid inlet manifold and a demister. The system may be remove at least 50 wt. % PM10 and/or PM2.5 particulate matter from the gas stream. | 02-27-2014 |
| 20140182453 | CENTRIFUGAL WET TYPE CLEANER - The present invention relates to a centrifugal wet type cleaner which collects contaminants within air using fine water particles to centrifugally separate the air and water from each other using the weight difference between the air and water, thereby purifying air. The centrifugal wet type cleaner has a swirl chamber in which contaminants are three-dimensionally collected using a large number of water particles sprayed by a rotating atomizing device to centrifugally separate the contaminated water having a heavy weight and collecting the contaminants from the air using a direct spiral flow generated at a downstream side of a centrifugal impeller. When compared to a conventional cleaner, since the centrifugal wet type cleaner has low energy loss and less noise, noise and energy may be reduced to improve the effect of preventing the discharge of fine dust. | 07-03-2014 |

The wet scrubber may include an inlet for receiving the fluid and a vortex chamber, in communication with the inlet, for causing at least a portion of the fluid to circulate. The wet scrubber may also include at least one diffuser for exhausting the fluid from the vortex chamber, the diffuser configured to substantially prevent fluid exhausted from the diffuser from recirculating back into the diffuser. A paint booth and a method of scrubbing a fluid are also provided. | 08-26-2010 |
