Abstract: A hybrid humidity control and air purification device and method for hybrid humidity control and air purification. The hybrid device is a single unit capable of humidifying dry environmental air, dehumidifying humid environmental air and removing particulates and contaminants from the air. The device controls the outgoing air to a relative humidity setpoint between 35-50% with negligible particulate matter content. Particulate matter is transferred to water, which may be supplied and flushed by an automatic water pumping system.

Abstract: A paint booth assembly includes a paint booth having a pair of side walls and a flood sheet extending between the pair of side walls to separate the paint booth between a spray portion disposed above the flood sheet and a paint recovery portion disposed below the flood sheet. The flood sheet defines at least one flood sheet opening, and a scrubber unit extends down from the flood sheet opening to establish a shared path of fluid communication of a flow of water from the flood sheet and a downdraft of process air from the spray portion to the paint recovery portion. A scrubber pod is disposed within the scrubber unit and defines a plurality of perforations to induce an initial mixing of the paint particles entrained in the downdraft of process air into the flow of water.

Abstract: A distillation probe includes a conduit having a central axis. In addition, the distillation probe includes a baffle assembly disposed in the conduit. The baffle assembly includes a plurality of axially-spaced baffles positioned one-above-the-other in a stack within the conduit. Further, the distillation probe includes a first helical cooling coil wrapped around the conduit.

The thermally conductive layer is configured to transfer thermal energy between the first helical cooling coil and the conduit.

Abstract: An object of the present invention is to provide a heavy metal removing apparatus which can efficiently remove the heavy metal contained in the dust produced by burning of the raw material containing the heavy metal, and a cement production system comprising the heavy metal removing apparatus. The heavy metal removing apparatus 10 comprises a cyclone separator 11 which separates exhaust gas containing the heavy metal from a part of the dust heated to a temperature equal to or more than a temperature at which the heavy metal can volatilize, a bag filter 13 which is connected to the subsequent stage of the cyclone separator 11 and separates the exhaust gas containing the heavy metal from the remainder of the dust, and a heavy metal removal tower 14 which is connected to the subsequent stage of the bag filter and removes the heavy metal from the exhaust gas.

Abstract: A chimney filter system featuring two or more filter housings mounted atop an industrial chimney stack and a reservoir fluidly connected to the lower filter housing via a first drain pipe that allows water to flow from the lower filter housing to the reservoir. The reservoir allows contaminants in the water to collect on the bottom surface of the reservoir. A second drain pipe is fluidly connected to the reservoir via a pump. The pump and second drain pipe deliver water from the reservoir to the upper filter housing.

Abstract: A fuel system for an LPI engine according to an exemplary embodiment of the present invention may include a reservoir disposed in a fuel tank, a recovery pipe inserted in the reservoir, and a fuel pump disposed in the reservoir and supplying LPI fuel, wherein liquefied fuel mixed with gaseous fuel recovered through the recovery pipe is separated in the reservoir and the liquefied fuel is pumped again by the fuel pump.

Abstract: A paint reclamation clarifier system in communication with a sump tank in a paint booth containing a carrier fluid for capturing paint droplets and a conduit for transporting the carrier fluid mixed with paint droplets to the reclamation clarifier system is presented. The clarifier system includes an influent port, a detackification agent inlet, a sludge tank in a lower portion of the clarifier for collecting the dispersed carrier liquid, where the paint droplets bond with the agent and settle to the bottom of the sludge tank, a sludge outlet, and, at least one effluent port located on or near an upper portion of a sidewall of the clarifier system permitting unsettled material to exit from the clarifier.

Abstract: A treatment system to efficiently remove lead from dust contained in extracted cement kiln combustion gas while reducing facility and running costs. A treatment system 1 comprising: a probe 3 for extracting a part of combustion gas, while cooling it, from a kiln exhaust gas passage, which runs from an inlet end of a cement kiln to a bottom cyclone; a classifier 5 for separating coarse powder from dust contained in the combustion gas extracted by the probe 3; a wet dust collector 6 for collecting dust from the extracted gas containing fine powder discharged from the classifier 5; and devices 12, 13 for feeding sulfurizing agent for sulfurizing lead contained in the kiln exhaust gas to the wet dust collector 6, and others. From the sulfurizing-agent feeders 12, 13 are preferably added the sulfurizing agents to a circulation liquid tank 7 or a pump 9 for circulating slurry.

Abstract: The present invention discloses a system for flue gas treatment, wherein the provided system comprises a quench module, a first control module, a filter collecting module, a wet scribing module and a regeneration module. In this system, parts of the particles contained in flue gas are removed in the quench module and the wet scribing module by a first scrubbing solution, and then in wet scribing module a second scrubbing liquid containing particles is formed. Next, the second scrubbing solution is treated in the regeneration module to form a third scrubbing solution, wherein the third scrubbing solution is then fed back to the quench module and/or the wet scrubbing module to substitute the first scrubbing solution for repeating what originally performed via the first scrubbing solution. Furthermore, this invention discloses a method for flue gas treatment.

Abstract: Methods and apparatus for separating solid particles from a fluid. One preferred embodiment includes a tank for settling particles out of the fluid, a conical chamber at the bottom of the tank, an outlet connected to conical chamber, and a conical auger within the conical chamber. The tank may have a tangential inlet that creates a fluid circulation that exerts a centrifugal force on the solid particles to increase the settling of particles out of the fluid. The tank may have a static spiral on the inner wall that helps small particles coalesce into larger particles that settle faster out of the fluid. The fluid content of the solids removed from the tank may be controlled by varying the rotational speed of the conical auger. The rotational speed of the conical auger may be varied depending on the torque required to rotate the conical auger.

Abstract: A wet gas stripper is provided for separating particulate matter entrained in a moving gas stream. The gas stripper includes a housing having a plurality of walls, and a gas inlet for receiving the moving gas stream into the housing and a gas outlet through which the moving gas stream is exhausted from the housing. A particulate collection area is formed at a base of the housing. A liquid spray element sprays a liquid against at least one of the walls of the housing above the particulate collection area to create a particulate-entraining mist. The mist defines a filtration medium for capturing the particulate matter entrained in the gas stream and carrying the particulate matter to the collection area for removal from the housing.

Abstract: A gas cleaning apparatus is disclosed which comprises a housing having an inlet adjacent a bottom portion thereof and an outlet adjacent a top portion thereof. The housing preferably has at least one radially-extending vane disposed along a longitudinal axis of the housing. A settling tank is fluidly connected at a top portion thereof to the base of the housing, at least one outlet fluidly connected to a waste treatment apparatus, and at least one outlet fluidly connected to the housing between the inlet and the outlet of the housing. The waste treatment apparatus preferably has at least one outlet fluidly connected to the housing between the inlet and the outlet of the housing.
