Technical field
Patent of the present invention belongs to chemical industry heat exchange and various materials hybrid reaction technical equipment, and specifically a kind of Double-jacketed fixed bed is anti-Answer device.
Background technology
Chemical reaction process is the core and key in Chemical Manufacture, for most courses of reaction, reacts adding of mediumHot mode and the efficiency of heating surface have significant impact to reaction efficiency and quality, and in this process of current industrial application, main equipment isDirectly the mode of mode of heating and shell and tube heat exchange heat supply provides heat, the reaction of catalytic mixing medium for reaction medium. The former is not because ofCan not directly use in a lot of reactions with the physics of medium, the limitation of chemical property, and in most of chemical reactionsCan not take this mode, limitation is very larger. Shell and tube heat exchange mode is in tube side by the high-temperature medium in shell sideReaction medium heat supply, the mode by heat exchange provides reaction temperature for reaction medium, and the shortcoming of this mode is manufacturing processRelatively flow process complexity, and only adopt the heat-supplying mode of individual layer, the lower material reaction efficiency that causes of efficiency of heat exchange is not high.
Summary of the invention
Technical problem to be solved by this invention is the problem for above-mentioned existence, and a kind of Double-jacketed fixed bed reactors are provided,Can improve material reaction efficiency, simple in structure, independence is strong.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of Double-jacketed fixed bed reactors, its feature existsIn, comprising outer tube, middle pipe, inner tube, upper end cover, upper sealing plate, lower shrouding and filter, described outer tube is coated at middle pipe, inPipe is coated at inner tube, the outer pipe, the pipe and the inner pipe central alignment, and outer tube and middle pipe are the hollow cylindrical tube of both ends open, upper and lowerOpening part all outwards forms round flange, and inner tube is the hollow cylindrical tube that top seal bottom centre has tapped through hole, on outer tubePortion has through hole and connects outlet pipe, and bottom has through hole and connects the first water inlet pipe, and inner tube and middle pipe top have through hole, and two logicalHole is connected by connecting pipe; Described filter is connected with middle pipe bottom, and filter center has tapped through hole, inner tube bottom surfaceJoin with filter end face, between inner tube and middle pipe, form material reaction chamber; Described lower shrouding is connected with outer tube bottom, lower shroudingOn have discharge opening connect discharge nozzle, lower shrouding center has tapped through hole, filter bottom surface and lower shrouding end face join; DescribedCentered by upper sealing plate, have the plectane of through hole, through-hole aperture is identical with middle pipe external diameter, and upper sealing plate is through middle pipe top and outer tube topBe connected; Described upper end cover is connected with middle pipe top, and upper end cover top center has through hole and connects feed pipe; The second water inlet pipe successivelyTapped through hole through lower shrouding, filter and inner tube bottom centre is threaded with lower shrouding, filter and inner panel.
Press such scheme, on described lower shrouding end face, the position in corresponding described material reaction chamber has ring groove, described discharging openingBe located on groove.
Press such scheme, described filter is circular slab, uniform several little on the position in corresponding described material reaction chamber on filterHole.
The invention has the beneficial effects as follows: 1, these fixed bed reactors are fitted together and are formed by three ascending pipe boxes of diameter, keep awayExempt from the form how common shell and tube is arranged with tubulation, simple in structure; 2, material reaction chamber by inner and outer tubes around, high-temperature mediumGood heat conduction effect, medium reaction efficiency is higher; 3, material reaction chamber is enough become by an integral ring-shaped cylinder, and globality better can makeMaterial contacts fully with catalyst, and therefore reaction efficiency is higher.
