Abstract
A fluid distributor includes one or more fluid transport main pipe. The fluid transport main pipe is configured to assume a closed shape when its centerlines and/or centerline extensions are joined end-to-end. Each of the fluid transport main pipe has at least one fluid inlet and is connected with a plurality of fluid transport branch pipes. Each of the fluid transport branch pipes has a plurality of open pores disposed along the length of the fluid transport branch pipe and a connection portion. The connection portion is configured to connect the fluid transport branch pipe to the housing after the fluid transport branch pipe passes through the housing of the vessel into the inner cavity.
Claims19
A fluid distributor adapted to transport a fluid to a vessel inner cavity, the fluid distributor comprising:
- one or more (preferably 1-8, more preferably 1-4 or 1-2) fluid transport main pipe(s);
- either one fluid transport main pipe is configured to form a closed shape (preferably a closed shape substantially conforming to the peripheral contour of the vessel, more preferably a substantially planar closed shape, more preferably a substantially planar circular, elliptical or polygonal shape, more preferably the closed shape is substantially perpendicular to the vessel centerline), when its centerline and/or centerline extension thereof are joined end-to-end;
- or a plurality of fluid transport main pipes are configured to form a closed shape (preferably a closed shape substantially conforming to the peripheral contour of the vessel, more preferably a substantially planar closed shape, more preferably a substantially planar circular, elliptical or polygonal shape, more preferably the closed shape is substantially perpendicular to the vessel centerline), when their respective centerlines and/or centerline extensions thereof are joined end-to-end, and each of the fluid transport main pipe(s) has at least one (preferably 1-3, more preferably 1) fluid inlet,
- a plurality of fluid transport branch pipes (preferably 5-100, more preferably 5-50) disposed on each of said fluid transport main pipes, each of said fluid transport branch pipes having a starting end and a terminal end (said terminal end being in a closed, semi-closed or open configuration, preferably a closed configuration), said starting end being connected to and in fluid communication with said fluid transport main pipe and said starting end and said terminal end defining a length L of said fluid transport branch pipe,
- a plurality of open pores (preferably 2-140, more preferably 6-60) disposed along the length of said fluid transport branch pipe in each of said fluid transport branch pipes,
- a connection portion provided on each of the fluid transport branch pipes (preferably, the connection portion is provided at a position closer to the starting end than the terminal end, and more preferably, the connection portion is provided at a distance from the starting end along the length direction of the fluid transport branch pipe of ¼ or less, ⅙ or less, ⅛ or less, 1/10 or less of the length L of the fluid transport branch pipe), the connection portion being configured to connect (preferably fix, more preferably air-tight fix) the fluid transport branch pipe to the housing (preferably an outer surface of the housing) after the fluid transport branch pipe passes through the housing of the vessel into the inner cavity.
A fluid distributor, which is a feeding distributor for uniformly distributing propylene ammonia mixed gas in a fluidized bed reactor, and the feeding distributor comprises:
- one or more distributor inlets;
- a plurality of transport branch pipes connected to and in fluid communication with the distributor inlets, respectively, and extending from the distributor inlets toward a reactor interior;
- the open pore, which open pore is arranged on the transport branch pipe;
- and
- nozzles disposed on the transport branch pipes around the respective open pores and coaxial with the respective open pores so that the propylene ammonia mixed gas passes through the distributor inlet, the transport branch pipes, the open pores and the nozzles and is finally uniformly distributed inside the reactor, and
- one or more feeding main pipes, wherein the feeding main pipe is disposed outside the fluidized bed reactor and is respectively connected to and in fluid communication with the one or more distributor inlets and the plurality of transport branch pipes.
