    摘要: An apparatus for facilitating solids transport in a pneumatic conveying l. The apparatus reduces the velocity of a gas within the pneumatic conveying line. The following describes a preferred embodiment. An inner cylinder is spliced into the line. An upper portion of the inner cylinder is made of a porous material. An outer cylinder having a diameter larger than the inner cylinder encircles the inner cylinder and defines a cavity therebetween. Two solenoid valves are associated with the outer cylinder; one for purging the gas and the other for introducing a reverse jet of gas to dislodge particles from the porous material. A pressure transducer measures fluctuations across the top of the inner cylinder and is connected to a control unit which, in turn, controls the valves.
