Abstract
The utility model provides a solid granule filter cylinder which mainly comprises an upper flange, a lower flange, a support ring plate, a cylindrical wire-mesh screen, a bottom plate and seal rings, wherein, the cylindrical wire-mesh screen takes the shape of a hollow cylinder; the meshes of the cylindrical wire-mesh screen are smaller than catalyst granules in diameter; one end of the cylindrical wire-mesh screen is welded with the support ring plate; the other end of the cylindrical wire-mesh screen is welded with the bottom plate; the outside diameter of the support ring plate is equal to those of flange plates; the end of the cylindrical wire-mesh screen, which is welded with the bottom plate, is inserted into the lower flange; a clearance is reserved between the outer wall of the cylindrical wire-mesh screen and the inner wall of the lower flange; one end of the cylindrical wire-mesh screen, which is welded with the support ring plate, is connected in an overlapping manner with the lower flange through the support ring plate; the upper flange is fixedly connected with the lower flange through bolts; and one seal ring is arranged between the upper flange and the support ring plate and between the support ring plate and the lower flange respectively. Due to the sealing function of the two seal rings, a ring-shaped groove and a screw hole are prevented from being formed on the lower flange, the strength of the lower flange is guaranteed, and the safety of the lower flange is increased.
Description
Technical field
The utility model relates to a kind of solid particle cartridge filter, relates in particular in the devices such as a kind of catalytic reforming, wraps up in the cartridge filter of taking the little amount of catalyst solid particle in gas phase or the liquid phase in order to remove.
Background technology
In reformer, exist in the mobile container of catalyst as regenerator and lifter etc., some oil gas vents are arranged, these export requirements outlet products do not carry catalyst.Filter and wrap up in the catalyst granules of taking in the oil gas by cartridge filter is set at the oil gas vent place in U.S. Universal Oil Products Company (UOP) and the domestic existing reformer.This cartridge filter by two flanges and be clipped in two between the flange the tubular silk screen, support ring flat-plate and blind plates are formed; There are two defectives in this cartridge filter: 1) for the support ring flat-plate is overlapped on the ring flange, need on ring flange, to offer ring groove, the support ring flat-plate is connected by screw with flange to be fixed, need on support ring flat-plate and flange, to process screw hole, ring groove and screw hole have weakened strength of flange, have increased security risk; 2) circular blind plate is welded in the lower end of tubular silk screen, causes the oil gas vent pressure drop to increase, and has influenced outlet product data, the reactiveness instability.
The utility model content
The utility model provides a kind of solid particle cartridge filter, is weakened, exists the technical problem of security risk with strength of flange in the solution prior art.
The solid particle cartridge filter that the utility model provides is made up of upper flange, lower flange, support ring flat-plate, tubular silk screen, base plate and sealing ring, the tubular silk screen is penetrating up and down cylindric, its mesh is less than the catalyst granules diameter, tubular silk screen one end welds mutually with supporting ring flat-plate, and the other end welds mutually with base plate; It is suitable with the ring flange external diameter to support the ring flat-plate external diameter, the tubular silk screen inserts in the lower flange with the end that base plate welds mutually, remain with the gap between the outer wall of tubular silk screen and the lower flange inwall, being welded with an end that supports ring flat-plate is overlapped on the lower flange by supporting ring flat-plate, upper flange is fixedlyed connected with lower flange by bolt, wherein reaches to support between ring flat-plate and the lower flange between upper flange and support ring flat-plate respectively to be provided with a sealing ring.
By the sealing function of two sealing rings, avoided on lower flange, offering annular groove and screw hole, guaranteed that strength of flange is not weakened, increased the security of flange.
In order fully to filter the catalyst granules in the oil gas, guarantee enough filter areas, the gap between the outer wall of tubular silk screen and the lower flange inwall should be greater than 3mm.
As further improvement project, on base plate, have some parallel penetrating strip holes, the width in hole certainly, also can be offered some uniform circular holes less than the catalyst granules diameter on base plate.
By perforate on base plate, can reduce the pressure drop of oil gas vent, make reactiveness more steady.
Description of drawings
Fig. 1 is the structural representation of cartridge filter of the present utility model;
Fig. 2 is the schematic diagram of base plate 3 among Fig. 1;
Among the figure, 1-supports ring flat-plate, 2-tubular silk screen, 3-base plate, 4-lower flange, 5-upper flange, 6-sealing ring, 7-strip hole, 8-oil gas inlet, 9-oil gas vent.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated, as shown in Figure 1, cartridge filter of the present utility model is made up of upper flange 5, lower flange 4, support ring flat-plate 1, tubular silk screen 2, base plate 3 and sealing ring 6, tubular silk screen 2 is penetrating up and down cylindric, its mesh is less than the catalyst granules diameter, tubular silk screen 2 one ends weld mutually with supporting ring flat-plate 1, and the other end welds mutually with base plate 3; It is suitable with the ring flange external diameter to support ring flat-plate 1 external diameter, tubular silk screen 2 inserts in the lower flange 4 with the end that base plate 3 welds mutually, keep a gap between the outer wall of tubular silk screen 2 and lower flange 4 inwalls, being welded with an end that supports ring flat-plate 1 is overlapped on the lower flange 4 by supporting ring flat-plate 1, upper flange 5 is fixedlyed connected with lower flange 4 by bolt, wherein reaches to support between ring flat-plate 1 and the lower flange 4 between upper flange 5 and support ring flat-plate 1 respectively to be provided with a sealing ring 6.
Wrap up in the oil gas of taking minor amount of catalyst particles and enter the solid particle cartridge filter through oil gas inlet 8, the filtration of the strip hole 7 of sub-fraction on base plate 3 enters the inside of tubular silk screen 2, is discharged by oil gas vent 9; Most of oil gas enters the gap between tubular silk screen 2 and the lower flange 4, enters tubular silk screen 2 inside after tubular silk screen 2 filters, and is discharged by oil gas vent 9.
Claims (4)
