摘要： A blast furnace where coke is combusted with oxygen, instead of air, and where a top gas comprising CO, CO2, H2, and without excess nitrogen is withdrawn from the upper part of the blast furnace, cleaned of dust, the H2/CO volume ratio adjusted to between 1.5 to 4.0 in a water shift reactor, water and CO2 are removed (increasing its reduction potential), heated to a temperature above 850° C. and fed back to the blast furnace above where iron starts melting (thereby increasing the amount of metallic iron reaching the dead-man zone and decreasing the amount of coke used for reduction). Also carbon deposit problems caused by heating the CO-containing recycled gas are minimized by on-line cleaning of the heater tubes with steam without significantly affecting the reduction potential of the recycled reducing gas.

摘要： An exhaust stream buffering system is described to temper a temperature profile and reduce a particulate load to permit heat recovery and cleaning. The buffering system may reduce the volatile temperature profile to even the temperature spikes, and produce a more even cyclical temperature profile. When used in steel making facilities, the buffered stream may also be augmented by blast furnace gases to provide additional energy for a heat recovery system.

摘要： A conventional dust-catcher for blast furnace gas comprises a pressure vessel, with a gas inlet and outlet dome (14), a separation chamber (16) and a lower dust hopper (18), and a diffuser pipe (26) extending axially through the gas inlet and outlet dome (14) into the separation chamber (16). To increase the separation efficiency of such a dust hopper (18), it is proposed to centrally arrange a flow deflecting chamber (50, 50′), having a smaller cross-section than the separation chamber (16), in the separation chamber (16), so that there remains an annular settlement chamber (52) between the inner wall of the separation chamber (16). The diffuser pipe (26) is connected to this flow deflecting chamber (50, 50′) so as to axially discharge a downward gas flow into the top end of the flow deflecting chamber (50, 50′), wherein this downward gas flow is deflected upward. An annular swirling device (58) with guide vanes (60) is arranged in the top end of the flow deflecting chamber (50, 50′) around the lower end of the diffuser pipe (26) and acts as outlet opening for the gas flow into the into the pressure vessel of the dust-catcher. The guide vanes (60) form a vortex gas flow rising around the diffuser pipe (26) upward into the gas inlet and outlet dome (14).

摘要： The preliminary cleaning stage for a dust extraction installation for blast furnace gas is comprised of a large-sized cyclone which comprises a vertical pressurized tank. A gas furnace gas line arriving from the blast furnace is connected to an axial delivery device situated at the upper end of the pressurized tank. The delivery device is configured such that it introduces the blast furnace gas into the pressurized tank in an axial direction. A swirl device with guide vanes is positioned below the axial delivery device and causes the blast furnace gas which is axially introduced into the pressurized tank to swirl about the axis of the pressurized tank.

摘要： Process and device for cleaning furnace gas includes flowing in a main flow direction (A) the furnace gas passes an array of bag filters. Filtered furnace gas having passed the filter bags, is partly returned via one or more nozzles which are moved along downstream ends of the bag filters. Each bag filter is passed at least once by at least one nozzle during a cycle. A nozzle passing a bag filter blows filtered furnace gas in a backflow direction (B) through said bag filter. The backflow direction is opposite to the main flow direction.

摘要： A cyclone has a cyclone body formed with a plurality of inlet ducts and an outlet. A first end of each of the inlet ducts is coupled to a downcomer and a second end of each of the inlet ducts is coupled to the cyclone body. The downcomer proximate the cyclone body is co-axial with and mounted to the cyclone body on a support. Each inlet duct exits the downcomer radially and enters the cyclone body tangentially.

摘要： Large amounts of industrial wastes are drawn by high vacuum into a scrubber and separator unit at the entrance of which the bulk wastes are flooded with water and reduced to slurry form. In the separator, the slurry is centrifugally spun and separated from the entraining air and delivered by gravity into a slurry tank from which the slurry is pumped to a remote disposal site. The air passes from the separator to a surge chamber where the air is spun and expanded and ridded of entrained moisture. The dry air in a clean state after passing serially through the vacuum producer and a silencer is expelled to the atmosphere. The equipment can be mounted on a vehicular base. The apparatus can operate to continuously and simultaneously remove and dispose of industrial wastes.

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.
