摘要： An apparatus for cleaning the exhaust gas of a high-pressure blast furnace comprises a coarse-particle separator, a prewasher and a differential-pressure annular gap washer traversed in succession by the gases. The exhaust gases can be passed through a main duct provided with an expansion turbine or through a bypass duct around the expansion turbine. The expansion turbine unit controls the back pressure at the blast furnace while a separate control circuit is provided to operate the differential-pressure washer with optimum efficiency. A quick-closing valve in the turbine-supply line and a quick-opening valve in the bypass line permits rapid switchover, a pressure-control valve in the bypass line maintains a constant backpressure at the blast furnace when the expansion turbine unit is shut down.

摘要： A hood assembly for use with cooking equipment having a plurality of units for separating foreign matter from air moving through the hood assembly. Each unit has a cylindrical tubular member having a passage for carrying the air and entrained foreign matter. A plurality of helical elements are located in the passage. The adjacent helical elements are located in 90.degree. relationship relative to each other so that the air moving through the passage is divided into separate helical paths which direct the air in spiral patterns whereby the foreign matter is separated from the air by the mechanisms of centrifugal force, adhesion and impaction. The foreign matter is collected and carried to a container. The cleaned air is recycled into the environment surrounding the hood assembly.

摘要： Stack gas is first passed through a coarse-particle separator and then a prescrubbing tower. Then this gas, which is under pressure, is passed through a pair of Venturi washers. The output side of one of the washers is connected directly to a droplet separator at the output of the system. The outlet of the other Venturi washer is connected through a turbine driving an electric generator and having its output side in turn connected to the droplet separator. The control body of at least the washer which is connected directly to the droplet separator is adjustable so as to maintain a constant back pressure in the system at the blast furnace from which the stack gas comes. The Venturi washer connected to the turbine is set up to pass at least four times as much of the gas as the other Venturi washers so that most of the gas passes through the turbine, undergoing a pressure drop that is transformed into the work of driving the turbine and generates electricity.

摘要： A combined scrubber-clarifier unit is disclosed adapted to remove particulate solids from a gas stream, the unit having improved scrubbing capability. The unit is designed to reduce the tendency of deposits of particulate solids to build up on interior surfaces of the scrubber unit tending to plug the unit. The wet scrubber is mounted atop a sealed sludge-clarification tank, the tank being large enough to provide a retention time of about 30 minutes for the slurry. The scrubber unit is one wherein the particulate-laden gas stream is directed through a venturi and directly impinged against the water held in the sealed sludge-clarification tank. The scrubber unit has a central, hollow chamber therein through which the gases exit from the scrubber unit after passage through the water in the tank. Mounted in the upper portion of the central chamber is a demister unit comprised of numerous slanted vanes which impart a swirling motion to moisture-laden gas passing therethrough to centrifugally separate the water and residual particulate solids from the gas on passage through the vanes. The water and particulate solids separated by the de-mister are collected and returned to the clarifying tank by a sump and drain pipes. Plugging of the drain pipes and build-up of particulate solids on the vanes of the de-mister unit are prevented by direct spraying of water adjacent the openings leading to the drains and against the vane surfaces at all times. The level of the water in the sludge clarification tank is maintained substantially constant by control means to assure optimum scrubbing capability.

摘要： A gas collector hood is located close to the mouth of a converter vessel and has a diameter which is not much greater than the mouth of the vessel. A mixture of oxygen together with entrained powered materials based on process requirements and a hydrocarbon fluid as cooling agent are blown through tuyeres in the bottom of the vessel and diffuse through the hot metal in the vessel. The inherently finer dust produced from the bottom-blown oxygen process requires that for proper air pollution control a non-combustion system be used to take advantage of the increased agglomerating properties of iron oxides when produced in reducing atmospheres. When blowing is initiated in this process carbon monoxide and hydrogen evolve immediately and in order to render the gases inert, air is aspirated into the gas collector hood so that an inert gas plug is formed which purges the exhaust system of combustion air. A short time after blowing is initiated, the hood is brought down to proximity with the vessel in which case only a small percentage of the theoretically required air for combustion is aspirated. Nitrogen is injected as required into the hood in addition to air aspirated to artifically create inertization to turn down a heat at high carbon levels, for emergency vessel turn down, and for special heats. Near the end of a normal low carbon heat, air is again aspirated into the hood so that an inert gas plug is formed for safe turn down of the converter. Control of the system is achieved through high response sensors based on a gas analysis system independent of the components and products of combustion in the gas phase, operated together with automatic suction control incorporated as part of the gas cleaning system.

摘要： Ducts serving for the exhaustion of dust-laden waste gases from a converter and from ancillary equipment lead to two scrubbing stations whence the purified gases escape through respective chimneys. The effluent from the main scrubbing station, serving the converter, is cleansed in a settling tank for recirculation to both scrubbing stations; the effluent from the secondary scrubbing station is fed to a preliminary stage of the main station through which it also returns to the settling tank. An annular cowl for the interception of peripherally escaping converter gases is connected to a duct normally communicating with the secondary scrubbing station; during charging of the converter, however, this duct is switched to the main scrubbing station which is then not traversed by converter gases.

摘要： The air cleaning device described herein uses the well known cleaning ability of a ''''venturi'''' scrubber arranged in a configuration which will allow efficient cleaning of dirt laden air at significantly lower horsepowers than other devices currently in use. The apparatus incorporates a venturi nozzle section for accelerating the air into the necessary high velocity component to break up the water droplets for adequate collection of sub-micron particles. By incorporating an efficient regain section on the downstream side of the nozzle and running this regain section directly into the inlet of an unhoused centrifugal backwardly inclined fan, we are able to fully utilize the velocity already generated and the energy contained within that high velocity air to create an integral venturi fan combination which will operate at significantly lower horsepowers than other devices using separate components. Other aspects of the device include a ''''Y'''' separator which removes a large percentage of the water from the water air mixture in the nozzle to further reduce the horsepower consumed in the fan wheel. The clean air passing through the fan wheel is then discharged into an enclosure which acts as a supporting structure for the entire device. This enclosure offers additional separation of the water mist from the air through possible centrifugal action of the fan wheel within the enclosure. The device then is able to collect air-borne matter using water or other liquids as the collecting media and is able to separate these such that the clean air is discharged for re-use, while the dirt laden water is processed through conventional means for final removal of the original airborne matter.
