Patent FR-2332791-A1 (FR)
Title: Suction fan for gases, incorporating hydraulic dust removal - has rotor-blades in staggered sets giving intimate gas-solid-liquid contact
IPC: B01D47/00
Filed: 1975-11-28
Abstract: An appts. which acts as a suction fan and also removes dust from a gas by the wet method incorporates a rotor, a casing and an atomiser. The rotor is driven by a motor and revolves on a shaft in the casing. The casing has a suction duct and an outlet and a circular opening concentric with the axis. The gas flows radially from the inlet to the periphery and a spray of water is injected into it from the atomisers as it enters the rotor. The rotor has two cheeks between which are radial paddles forming radial channels in which the gas flows. The paddles are short and are arranged in sets at different distances from the axis. Those in one set are partly between those of another set. The baffling so produced imparts a shock effect to the stream of gas and water and gives intimate contact between gas, solid and liq. Because of the repeated shocks imparted by the paddles the invention gives better mixing of the gas, the dust and the wetting liq. than existing appts. The capacity is therefore greater and the consumption of energy is less. The appts. does not exhibit the critical zone which existing appts. exhibits at low rates and which reduces their efficiency. This is of particular interest if the flow of gas to be cleaned is variable, as e.g. in steel making.
Patent FR-2298852-A1 (FR)
Title: Electrochemical metal strip cleaning - in mercury contact and phosphoric acid baths before flushing and dewatering tanks
IPC: G11B5/84
Filed: 1976-01-09
Abstract: In a process to clean the surface of metal foil strip from oxide films and other impurities, the strip is pulled through a mercury bath where it receives a positive charge by electrical current. Its passage through a tank containing a phosphoric acid solution and a negative electrode cleans the strip surface by electrochemical action. A water flushing bath and a bath containing dionized water to rinse off all impurities complete the process. This removes not only oxide films but also dirt, burrs, oil and all other contaminations from the strip surface. Clean metal strips are produced without expensive apparatus. The method is suitable forthe treatment of the magnetic tapes made of vanadium-cobalt-iron alloy, used in black boxes for aircraft which have to withstand the impact of a crash and a possible fire.
