Embodiment Construction

[0034] Such as Figure 1a , Figure 1b , Figure 2a , Figure 2b , image 3 , Figure 4a , Figure 4b , Figure 5 As shown, a barrier liquid distributor includes a barrier liquid distribution pipe 1 and a distribution pipe support block 2; the barrier liquid distribution pipe 1 is a structure with one end fixedly supported and one end simply supported along the vertical and horizontal directions; the barrier liquid The distribution pipe 1 is inserted into the pressure vessel, and one end of the barrier liquid distribution pipe 1 partially overlaps with the distribution pipe support block 2 along the vertical direction to form a support relationship.

[0035] The barrier liquid distribution pipe 1 includes a liquid distribution pipe 3, a distribution pipe plug 4, a distribution pipe flange 5 and a dust-proof baffle 6;

[0036] One end of the distribution pipe plug 4 is an eccentric circular sleeve structure, and the other end is a concentric circular sleeve structure. The...

Abstract

The invention relates to a shielding flow distributor including a shielding flow distribution duct and a distribution duct support block. The shielding flow distribution duct comprises a flow distribution duct, a distribution duct stopper, a distribution duct flange and dust-proof baffles. One end of the distribution duct stopper has an eccentric circular sleeve structure, while the other end has a concentric circular sleeve structure and is connected with the distribution duct flange. One end of the distribution duct is inserted in and fixed to the eccentric circular sleeve structure, the other end is disposed outside of the eccentric circular sleeve structure and is supported by the distribution duct support block. A pair of dust-proof baffles are mounted outside of the distribution duct stopper and are distributed along the length direction of the distribution duct, and an enclosed structure is defined by the dust-proof baffles and the outer wall of the flow distribution duct, the cross section being a water-drop shape. The invention reinforces the strength of maximum force bearing position of the shielding flow distribution duct, reduces actual stress of shielding flow distribution duct, so that a problem of fatigue and damage of the shielding flow distribution duct is solved, and safety operation cycle is promoted.

Description

technical field [0001] The invention relates to internal parts of a multi-zone circulation reactor in the field of petrochemical equipment, in particular to a barrier liquid distributor. Background technique [0002] In the polypropylene process technology, the multi-zone circulation reactor is used to realize the multi-zone circulation polymerization, and a production line produces homopolymerization products, random copolymerization products, impact copolymerization products and ternary copolymerization products; the multi-zone circulation reactor is a gas phase reaction It is divided into two parts: the lifting section and the settling section; the gas-phase propylene enters from the elbow at the bottom of the riser, and enters the settling section obliquely downward through the riser and the big elbow at the top, and the upper part is an obliquely downward cyclone inlet structure , There are upper and lower sets of barrier fluid distribution pipes inserted into the settl...
