Sediment incrustation distributor

Abstract

The invention discloses a begrime distributor, which can overcome the defects of present technique which uses begrime box or the layer of protective agent to cause fast increase of pressure drop, odd distribution of gas and liquid and influence on the normal operation in the working process. The invention has the double functions of dirty collection and distribution, which can improve the material flow distribution, decrease the volume of reactor occupied by inner element, increase the carrying amount of activator, to realize better effect. The inventive begrime distribution comprises a begrime distributing base plate and a begrime device. Wherein, said begrime device is arranged on the begrime distribution base plate; the begrime device is a sleeve barrel structure formed by outer and inner cylinder cages; the top of begrime device has a baffle; the side walls of outer and inner cages have filter screens; the bottom of inner cylinder cage and the distributing base plate of begrime device have open structures at their relative positions to the bottom of inner cylinder cage; and the lower outlet of regime distributor has a flow-broken plate. The inventive begrime distributor has the property characters in the working process that gas-liquid distribution, unimproved pressure drop, prolonged working period, better operation flexibility, wider application to variable mediums, and high availability ratio of stuffing (protective agent). The invention can be used in variable fixed-bed reactor, especially in the area of petrochemical industry.

Description

technical field [0001] The invention relates to a fouling distributor, which belongs to the internal components of reactors, especially the internal components of fixed-bed reactors in petrochemical industry, and is especially used for filtering metal impurities and suspended particles in liquid in fixed-bed reactors that are easy to scale. and fouling components for fluid distribution. Background technique [0002] In many fixed-bed reaction processes, the distribution plate structure is widely used on the catalyst bed of the reactor, and the fouling basket at the bottom of the distribution plate occupies too much volume of the reactor, which reduces the catalyst loading. Although the distribution plate above the catalyst bed of the reactor distributes the material, the feed often contains some solid matter, which will be deposited on the top of the catalyst bed, causing the bed pressure drop to be too high or even blocked, shortening the operating cycle and increasing Ope...
