Abstract
A catalyst loading small kit used for a moving bed reactor comprises a casing and a small hole (3), and is characterized in that the casing adopts a revolving body formed by two half parts and a cylindrical housing (2) in the middle part, wherein the two half parts include an upper elliptical casing and a lower elliptical casing and the small hole (3) is formed on the casing; the mutual proportionis as follows: H accounts for 25 percent to 50 percent of D, and b accounts for 40 percent to 80 percent of a, the aperture ratio ranges from 30 percent to 70 percent, the aperture ranges from 1 to 10 mm, the casing is divided into two parts along the middle in a manner of being perpendicular to the revolving shaft, and the two half casings are mutually connected with screw threads or bayonets; wherein, the H represents the length of the cylindrical housing, the D represents the diameter of the cylindrical housing, the a represents the semi-major axis of the elliptical housing, and the b represents the semi-minor axis of the elliptical housing. The utility model has the advantages that the moving resistance among fluids is small, the integral rigidity of the small kit is strong, the holding capacity of per-unit outer surface is large, and the catalyst loading small kit not only reduces the abrasion or the crush of the catalyst, but also ensures that catalyst bed layer is move smoothlyduring the operation.
Description
Technical field
The utility model belongs to a kind of moving-burden bed reactor and loads capsule with catalyst.
Background technology
Gas-solid catalysis moving bed reaction process and gas-solid catalysis moving-burden bed reactor have strict requirement to the intensity or the wearability of the catalyst of solid particle.When the intensity of the catalyst of solid particle or wearability not enough and produce broken or during wearing and tearing, the gas channel that can result in blockage increases gas-flow resistance, thereby the influence operation.The conventional method that overcomes this problem is to improve the intensity or the wearability of solid catalyst.Yet the Study of Catalyst that petrochemical industry is used itself is exactly one relates to the quite complicated problem of numerous factors, should consider the requirement of chemical reaction aspect, as activity of such catalysts, specific area, porosity etc., consider the requirement of mechanical environment aspect again, as intensity, abrasiveness, temperature, pressure etc., this has increased many difficulty just for selection, proportioning, making, use, the recovery of catalyst.So, paid close attention to overcoming these problems for a long time.
Summary of the invention
The purpose of this utility model provides a kind of wearing and tearing that not only can reduce catalyst or broken but also can guarantee that the beds moving-burden bed reactor that moves smoothly in operation loads capsule with catalyst.
In order to make more eurypalynous high activity, high stability but the solid catalyst of intensity shortcoming can be used for the operation of chemical industry moving bed reaction, reduce the development difficulty of catalyst, from the breakage and the wearability of extenuating catalyst granules, catalyst granules is filled in the capsule of the present invention, together drop into again and participate in chemical reaction in the moving-burden bed reactor.Have a large amount of apertures on the capsule wall or directly make with silk screen, this structure can not hinder the diffusion of reacting gas and flow, and the rigidity of box wall can play catalyst protection and reduce breakage rate simultaneously.
This moving-burden bed reactor special-purpose catalyst filling capsule profile is that housing and aperture are formed, it is characterized in that housing is the upside of ellipse shell, following semiellipse shell, middle revolving body for the cylinder cover composition has aperture on the housing, ratio is H=0.25-0.5D mutually, b=0.4-0.8a, percent opening are 30-70%, aperture 1-10mm, housing is separated along the centre perpendicular to gyroaxis, adopt screw thread or bayonet socket to interconnect between the two halves housing; Wherein H represents cylinder cover length, and D represents the cylinder cover diameter, and a represents oval shell major semiaxis, and b represents oval shell semi-minor axis.
But metal material punching presses such as the material steel plate of aforesaid capsule or steel wire are made, and also can adopt organic synthesis material injection mo(u)ldings such as plastics.
The shape and size ratio of capsule is the design key that is effective to chemical industry moving bed reaction process loading catalyst particle capsule.The shape ratio of capsule depends on the mobile requirement in moving bed, and the size of capsule depends on the requirement of moving-burden bed reactor diameter; The perforate on capsule surface and percent opening depend on the granularity of catalyst.The material of capsule can carry out selection according to concrete chemical industry operation atmosphere.Material can be made with metal material punching presses such as corrosion resistant plate or steel wires, also can adopt organic synthesis material injection mo(u)ldings such as plastics.
This capsule not only can be used for moving-burden bed reactor, also can be used for the operation of reactors such as fixed bed, ebullated bed, even also can be used for the operation of the chemical unit of the types such as filtration, absorption, absorption under liquid-solid, the gas-solid state.Has the very wide scope of application at aspects such as chemical industry, food, environmental protection.
The utlity model has following advantage:
(1) moving resistance is little between fluid;
(2) integral rigidity of capsule is big;
(3) volume that comprises of the external surface area of unit is big;
(4) capsule can be made into two halves, separates along the centre perpendicular to gyroaxis, adopts screw thread or bayonet socket to interconnect between the two halves.
(5) wearing and tearing of catalyst or broken but also can guarantee in operation the moving smoothly of beds not only can have been reduced.
