Abstract
The utility model relates to a novel synthetic tower internal member with cover plates and a barrel sealing structure of a contact agent basket. A barrel body, a big cover plate and a small cover plate of the utility model can be simultaneously sealed by novel sealing gaskets, bolts and nuts. The utility model can be widely used for ammonia and methyl alcohol synthetic towers, particularly a cold pipe type synthetic tower internal member, such as, a uniform temperature type methyl alcohol synthetic tower internal member and a JL type ammonia synthetic tower internal member. The internal member of the utility model is used, and the utility model has the advantages of simple structure, and convenient disassembly and assembly.
Description
The utility model is that a kind of tool is simple, effective, the ammonia converter internals of convenient, reasonable hermetically-sealed construction, is used for ammonia synthesis and methanol synthesis reactor, belongs to the Chemical Reaction Engineering field.
Welding is perhaps adopted in the top cover of basket and the sealing between cylindrical shell in the ammonia converter internals that uses at present both at home and abroad, adds leg steel sealing ring (seeing petro chemical industry publishing house " ammonia convertor " 1977) at stop portion after perhaps adopting Bolt Connection.The internals of this welded seal are brought very burden to catalyst replacing, internals dismounting.
The seventies is domestic begin to occur a kind of gas earlier through central tube after the single tube deflector type synthetic ammonia tower inner parts of cold pipe, its processing performance is better than existing pair of sleeve pipe, three sleeve pipe ammonia convertor spares.But because of its cold pipe and central tube top directly welding, so normal in using cold pipe and the drawing crack of central tube junction take place.Lou Shoulins in 1981 etc. have designed independently dicyclo cold tube bag, and cold pipe separates with central tube, and giving vent to anger by being located at the collection chamber on the internals large cover of central tube arrived cold tube bag through air entraining pipe.Air entraining pipe and central tube pass through packing box seal respectively, thereby have avoided temperature stress, have solved structural reliability problem.Present this ammonia tower internals structure is used widely, but the internals of this band collection chamber need be carried out two road welded seals between basket large cover and cylindrical shell, collection chamber minor flaps and large cover when catalyst is installed, still show trouble.
The purpose of this utility model is to seek the more reactor internals of advantages of simple positiver sealing pattern of structure.
Adopt the ammonia converter internals of novel seal between a kind of basket cover plate and cylindrical shell, mainly be the cylindrical shell 1 and the large cover 2 of internals, minor flaps 3, between the three by one gasket seal 4 and bolt and nut 5,6, carry out the sealing between cylindrical shell 1, large cover 2 and the minor flaps 3 simultaneously, the material of gasket seal 4 can be used the spirotallic gasket of stainless steel expanded graphite, also available other pads.Adopting the internals of sealing can be the cold-tube type methyl alcohol synthetic reactor, for example homogeneous temperature type methyl alcohol synthetic reactor internals; Also can be the tube type ammonia converter internals that has heat insulation layer that is provided with collection chamber, for example JL type tube type ammonia converter internals.Below in conjunction with accompanying drawing, be described further.
Fig. 1 is a kind of cold-tube type synthetic tower sketch.Internals B places urceolus A among the figure, inlet tower gas arrives basket R after the heat exchanger H heat exchange of bottom, in basket R through central tube 7 to collection chamber 8 again through air entraining pipe 9 in the pipe of cold tube bag 10 with the outer catalyst layer K of pipe in the reaction gas heat exchange, the gas that goes out cold tube bag removes bottom heat exchanger H after catalyst layer reacts.Before internals are used, need open big minor flaps, put into catalyst, need adorn the ammonia catalyst, methyl alcohol synthetic reactor is then needed armoring pure catalyst ammonia convertor; Install large cover 2 on the catalyst bonnet, welded seal 11 between large cover 2 and cylindrical shell, install the filler in large cover upper center tube 7 and air entraining pipe 9 stuffing-boxes then; And then at large cover 2 and 3 welded seals 12 of minor flaps, and will change catalyst by the time the time again gas cutting remove this two roads seal-weld, install and use to internals and make troubles.Particularly shorter to catalyst life, it is particularly outstanding to change frequent methanol column internals.Lou Shoulin was when design homogeneous temperature type methyl alcohol synthetic reactor in 1992, with basket large cover and shell flange, draw bail between large cover and minor flaps makes the form with the bolted gasket seal into, made things convenient for dismounting (seeing Chemical Engineering Design communication supplementary issue in 1993), but the multiple-sealed hidden danger that has increased material and leakage.
Fig. 2 is the homogeneous temperature type ammonia converter internals of the two-in-one novel sealing structure of a kind of cover plate of the utility model and cylindrical shell.
Fig. 3 is a novel sealing structure part enlarged drawing among Fig. 2.
Internals large cover 2 is bearing on the step of cylindrical shell 1 as seen from Figure 3, the outside of large cover 2 and cylindrical shell 1 inboard each by the concave indentation step in conjunction with forming a concave shape groove, then there is convex tenon face to place the concave shape groove on the minor flaps 3, one gasket seal 4, minor flaps 3 and cylindrical shell 1 usefulness bolt 5, nut 6 fastening pie graph 3 middle cylinder bodies 1 and large covers 2 are then arranged, multiple-sealed between large cover 2 and the minor flaps 3 and between minor flaps 3 and the cylindrical shell 1 between the male and fomale(M﹠F).Fig. 2 middle cooling pipe courage 10 reach basket bottom constitute in the cold tube bag the full bed of cold air to and stream and pipe outside catalyst layer gas converting heat, i.e. homogeneous temperature type methyl alcohol synthetic reactor internals.
Fig. 4 is the JL type synthetic ammonia tower inner parts of the two-in-one novel sealing structure of a kind of cover plate and cylindrical shell.With cold tube bag 10 bottoms of Fig. 2 different is its basket adiabatic catalyst layer K is arranged
DOther structure ammonia converter internalses for not establishing collection chamber do not need to establish minor flaps again, only need seal between cover plate and cylindrical shell, with one gasket seal 4, bolt and nut 5,6, carry out the sealing between cylindrical shell and the cover plate.
The homogeneous temperature type methanol column of the novel sealing structure that the utility model cylindrical shell is two-in-one and synthetic ammonia tower inner parts are all successfully carrying out factory application and are obtaining good result, show as without gas welding and gas cutting, can not damage cover plate, easy accessibility, the replacing catalyst is quick, reduce and avoided leakage, be subjected to the user and welcome.
