    摘要： A feeder arrangement for a slurry transport system, which is preferably a hydro hoist, includes a chamber with a high pressure water inlet, a low pressure water outlet, and a low pressure solids inlet at a top end. The low pressure solids inlet has a transfer chute that opens into a lower section of the chamber to maintain a clear-water environment adjacent the top end. A high pressure solids and water outlet is provided at a bottom end. The inlets and outlets are controlled by suitable valves. Three such chambers are preferably operated together in sequence between incoming and outgoing columns in a mine.

    摘要： An object of the present invention is to provide a technique in which deposition of powder during pneumatic transport can be inhibited by a pipe body having a simple structure. The present invention is a pipe for transporting powder including a transport path which has a portion formed by a curved pipe and through which pneumatically transported powder passes, and a blowing path through which a gas is blown into the transport path from an opening formed on an inner circumferential surface of the curved pipe, in which the blowing path blows the gas in a direction in which the gas blown into the transport path from the opening forms a swirling flow along the inner circumferential surface of the curved pipe.

    摘要： Methods and systems for transferring feed materials between zones having substantially different pressures, where the transfer can be continuous or semi-continuous. The methods and systems include a plurality of lock hoppers to receive feed material from a low pressure zone and pressurize it with fluid to a pressure of a high pressure zone. The pressurized material can be discharged to a circulation loop, which carries the pressurized material to one or more receiving unit(s) of a pressurized system. At least some feed material remains in the receiving unit(s) and at least a portion of the fluid exits to become part of the circulation loop. After discharge, the lock hoppers can be depressurized so the next pressurization cycle can begin with additional feed material. The lock hoppers can be operated in a time-staggered manner to provide continuous or semi-continuous transfer of material.

    摘要： A fish pumping system for moving upload water and fish includes a buffer pipe section having an upstream end and a downstream end. An inlet valve assembly is at the upstream end and provides fluid communication between the buffer pipe and an upstream fish origin. An outlet valve assembly is at the downstream end 5 and provides fluid communication between the buffer pipe and a fish destination. An inlet branch pipe is in fluid communication with the upstream end and an outlet branch pipe is in fluid communication with the downstream end. A production water piping circuit is in communication with the inlet branch pipe and the outlet branch pipe and forms a loop with the buffer pipe section. The 10 production water circuit pumps production water into the buffer pipe section through the inlet branch pipe and out from the buffer pipe section through the outlet branch pipe.

    摘要： A system is provided for passing matter in a flow passage of an oil and/or gas drilling or production installation, in particular for passing trash or drill cuttings in a drilling fluid return line. The system includes at least two valves arranged in series in said passage; and a control device configured to selectively or sequentially actuate said at least two valves, such that the material is allowed to pass said at least two valves in the passage. A method is also provided for passing trash or drill cuttings in a drilling fluid return line.

    摘要： The present invention relates to the control of flow of a particulate feed to a reactor, and in particular provides a process for providing a slurry of particulate matter to a reactor, comprising providing a slurry comprising said particulate matter and diluent, and passing said slurry to the inlet of a reactor feed pump from where it is then pumped to the reactor, characterized in that a stream of additional diluent is also passed to the inlet of the reactor feed pump, the reactor feed pump is operated at an essentially constant volumetric flow rate, and the amount of particulate matter in slurry passed into the reactor is adjusted by adjusting the flow.
