Abstract
The utility model discloses a radial flow urea converter, which comprises a cylindrical vessel (1) provided with a plurality of trays (2) inside, which is characterized in that: the nicks are arranged between the inner surface of the vessel (1) and the trays (2). The trays (2) are provided with salient (4) on the end near the nicks (3), and holes (5) are arranged on the top of the salient (2) and the sidewall of the end far from the nicks (3). Every two adjacent trays are alternatively arranged with a horizontal rotating angle of 180 degrees. The predominant characteristic of the utility model is that the device improves the urea generating rate by changing the shape of trays, that is to say, among the methods using the same number of trays. The utility model has higher efficiency. Besides, the utility model has the advantages of simple structure and easy to product and install.
Description
Technical field:
The utility model relate to a kind of under HTHP the reactor by ammonia and carbon dioxide urea synthesis, the high radial-flow type urea synthesizer of especially a kind of production rate.
Background technology:
Chang Yong reactor for synthesis of urea was upright cylinder type in the past, and material enters from the bottom, and synthesis reaction mixture is discharged from top.This is a typical gas-liquid bubbling reactor, and liquids and gases all are and the stream axial flow.Because turbulent flow mixing, molecular diffusion and VELOCITY DISTRIBUTION between gas-liquid, the difference of material density cause existing in the reactor serious liquid axial backmixing phenomenon.This phenomenon has reduced the initial material concentration of reaction zone unit volume significantly, has reduced reaction rate then, causes the urea production rate to reduce greatly.
In order to overcome above-mentioned shortcoming, a plurality of column plates mostly are set in the present reactor, be separated into a plurality of reaction zones, to reduce liquid dispersion, improve the urea production rate.Existing column plate has porous sieve plate type, hump type, V-type, tongue tray to add aperture sieve plate type, ball cap type and siphonic etc.But if think further to improve production rate, have only quantity to realize, thereby make the structure of reactor complexity, be difficult for processing and installation by increasing column plate.
Summary of the invention:
The utility model is at the deficiencies in the prior art, improve a kind of simple in structure, high efficiency radial-flow type urea synthesizer.
Technical solution of the present utility model is: a kind of radial-flow type urea synthesizer, be provided with cylindrical pressure vessel 1, in container 1, be provided with a plurality of column plates 2, it is characterized in that: 2 of the inwall of container 1 and column plates form breach 3, column plate 2 is provided with projection 4 at nearly breach 3 ends, and the top of projection 4 and the sidewall of breach far away 3 are provided with hole 5; Two adjacent column plates 2 are arranged alternately for horizontally rotating 180 °.
Described protruding 4 is the n type.
Described protruding 4 span b is 0.5～1.0 with the ratio of height h.
Described protruding 4 span b is 20～200mm, and height h is 20～200mm; The diameter in described hole 5 is 2～15mm.
Outstanding feature of the present utility model is to need not to increase the number of plates, only just realizes improving the purpose of urea production rate by the shape that changes column plate.In this reactor, be separated into a plurality of reaction zones with polylith radial-flow type column plate, all material is that radial level flows in each reaction zone, present the piston type activity characteristic, there is not axial backmixing in liquid, there is not the ditch flow short-circuit, do not have viscous flow, thereby improved the average response speed of the generation urea in the reaction zone, the production efficiency that improves reactor for synthesis of urea reaches more than 10%, produces urea per ton simultaneously and can reduce by 40～100kg steam consumption.This apparatus structure is simple, is easy to processing and manufacturing and installation.

Described protruding 4 can be semicircle, triangle, are preferably the n type.
Described protruding 4 span b is 0.5～1.0 with the ratio of height h.
Described protruding 4 span b is 20～200mm, and height h is 20～200mm; The diameter in described hole 5 is 2～15mm, preferred 4～8mm.
The diameter of its mesopore 5 and quantity can determine according to air velocity and amount of gas, and the flow through speed of aperture of gas preferably remains in 0.5～10m/s scope.
The area of breach 3 can determine that liquid preferably remains in 0.04～1.5m/s scope by the speed of breach according to flow rate of liquid and amount of fluid.
