Patent NL-6818881-A (NL)
Title: Vertical vessel fluid distribution system
IPC: B01J8/02
Filed: 1968-12-31
Abstract: Material passing through the vessel can be sprayed evenly with fluid using a minimum number of fluid distribution channels. If combustible fluids are used uniform combustion occurs across the bed. The system comprises several fluid distributors horizontally mounted, one above the other, wall to wall in a shaft vessel. Orifices direct fluid horizontally from both sides of each distributor at the same static pressure to provide a uniform amount of fluid to each unit of volume around the orifice. Enough distributors are provided to obtain a uniform amount of fluid per unit of volume throughout the horizontal zone. Each distributor may be a liquid supply pipe inside a gas supply pipe with orifices arranged so that liquid may issue along with gas. Each distributor may be a circular conduit with upper and lower coolant jackets with an exposed space between containing the orifices.

Title: Coarse granule crystallisation plant - for salt solns. has air/gas feed system
IPC: B01D9/00
Filed: 1974-01-18
Abstract: Salt soln. esp. iron sulphate, is fed into the bottom of a crystn. vessel so that it passes into a central guide pipe contg. a vane type stirer. From this central pipe it passes upwards into the evapn. chamber connected to a vacuum condenser extractor and also to a first annular channel around the guide pipe. The outer wall of this channel has a peripheral lowred slot leading in from a second annular chamber in which there is a steady recirculation current of the progressively concd. soln. The stirrer shaft is within a hollow inner pipe with an open gland at the top allowing gas air or a liquid (e.g. warm water) to enter to free the shaft from being jammed by crystals. This deliberate leakage promotes the action of the stirrer.

Patent PT-69649-A (PT)
IPC: C02F3/18
Filed: 1979-05-22
Abstract: The invention concerns an apparatus for the conversion of pollutants contained in effluents and effluent sludges, particularly of harmful substances and especially of excreta, into harmless substances with one or more hollow bodies rotatably arranged in a conversion pool or sludge aerating pool, which bodies emerge at one side of the pool completely out of the water or sludge and become completely immersed at the other side and whose part which is uppermost at the emerging side is lowermost at the immersion side, and vice versa. There is the danger, with such hollow bodies, that over time sludge settles in the hollow bodies. An anaerobic fermentation may take place in this settled sludge, during which the harmful substances rot but do not decompose. To prevent settling of sludge in the hollow bodies, it is proposed according to the invention to use hollow bodies which are laterally closed and opened at the top and below, and which are subdivided by an imperforated partition wall extending approximately parallel to the upper and lower opening.
