Abstract

The utility model provides a top that be listed as quick packaging structure of tubular reactor catalyst, a pair of spring (4) are located reaction tube (1) respectively and a throat makes progress, and the wide -mouth is downward that the bottom, and the throat of top spring (4) is downward, and the wide -mouth makes progress, bottom spring (4) support frame (5) comprise a pair of support to the connection intersects vertically, the top and the bottom of reaction tube (1) are equipped with the mounting groove that matches with support frame (5) respectively, and install respectively in the top and the bottom of reaction tube (1) a pair of support frame (5), and a pair of spring (4) contact with a pair of support frame (5) respectively. The utility model discloses a solve the current quick encapsulation problem that is listed as tubular reactor reaction tube catalyst, it is convenient to make the reactor catalyst change, and the operation is reliable to improve the life of reactor, reduce equipment use cost.

Description

A kind of fast packing structure of shell and tube reactor catalyst
Technical field
The utility model relates to petrochemical industry, is specifically related to a kind of fast packing structure of shell and tube reactor catalyst.
Background technology
At present, shell and tube reactor is the widely used a kind of reactor of petrochemical industry, and usual tube side medium is reaction mass, and shell side medium is heat medium, and reaction tube is built with catalyst and porcelain ball, and reaction tube upper and lower side is catalyst sealing assembling structure.Because reaction tube inner catalyst often will be changed, this just requires that catalyst sealing assembling structure wants easy accessibility, and existing shell and tube reactor reaction tube catalyst sealing assembling structure mostly is screw plug structure, and plug screw is offered through hole and is convenient to material stream passed, plug screw screws in from reaction tube end, realizes the encapsulation to catalyst.Due to processing and perforate reason, this structure is only applicable to the larger reaction tube of diameter, and is ensure enough heat exchange areas, and reaction tube will cause more greatly reactor diameter to strengthen, thus increases the investment of equipment.On the other hand, under reaction tube is operated in high temperature for a long time, is threaded at high temperature yielding and damages, make plug screw not screw out and to block, cause reaction tube cannot more catalyst changeout, thus reactor is scrapped, shorten the service life of reactor, reactor use cost raises.
Summary of the invention
The purpose of this utility model is exactly for the above-mentioned deficiency of current existing shell and tube reactor reaction tube catalyst sealing assembling structure, and provides a kind of fast packing structure of shell and tube reactor catalyst.
Technical scheme is as follows: a kind of fast packing structure of shell and tube reactor catalyst, it comprises reaction tube, it also has and to match a pair spring and pair of supporting that use with reaction tube, described spring is circular cone shape, a pair spring lays respectively at top and the bottom of reaction tube, and the reducing of top spring is downward, wide-mouth upwards, the reducing of bottom spring upwards, wide-mouth is downward, support frame as described above is made up of pair of brackets, and the connection that intersects vertically, the top of described reaction tube and bottom are respectively equipped with the mounting groove matched with bracing frame, pair of supporting is arranged on top and the bottom of reaction tube respectively, and a pair spring contacts with pair of supporting respectively.
The beneficial effects of the utility model are: the purpose of this utility model is the fast packing problem solving existing shell and tube reactor reaction tube catalyst, reactor catalyst is changed convenient, reliable, thus improve the service life of reactor, reduce equipment use cost.

Fig. 3 is support frame structure schematic diagram.
Detailed description of the invention
As Fig. 1, 2, shown in 3, the utility model comprises: reaction tube 1, it also has and to match a pair spring 4 and pair of supporting 5 that use with reaction tube 1, described spring 4 is circular cone shape (see figure 2), a pair spring 4 lays respectively at top and the bottom of reaction tube 1, and the reducing of top spring 4 is downward, wide-mouth is (see figure 1) upwards, the reducing of bottom spring 4 upwards, wide-mouth is downward, support frame as described above 5 is made up of pair of brackets, and the connection that intersects vertically, the top of described reaction tube 1 and bottom are respectively equipped with the mounting groove matched with bracing frame 5, pair of supporting 5 is arranged on top and the bottom of reaction tube 1 respectively, and a pair spring 4 contacts with pair of supporting 5 respectively.
Catalyst packing order is: load reaction tube 1 lower end spring 4; Load lower end bracing frame 5; From reaction tube 1 top filling porcelain ball 3, catalyst 2; Load reaction tube 1 upper springs 4; Load upper support shelf 5; Filling work completes;
Unloading catalyst order is: dismounting upper end bracing frame 5; Dismounting upper end spring 4; Dismounting lower end bracing frame 5; Dismounting lower end spring 4; Unload porcelain ball 3, catalyst 2.
According to the difference of catalyst weight and reaction tube pressure drop, select different springs and support, make firm supporting, can not subside because supporting and leak agent.
Reaction tube inner wall of end only needs the slotted eye processing mounting or dismounting and supporting bracket, easy to process, thus is applicable to large pipe with small pipe diameter, expands the specification limit of reaction tube, reduces the investment that caliber can reduce reactor.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope all belonging to the invention.
