The channel plate is arranged between the two cambered plates. One arc side of each cambered plate is welded on a tower body inner wall through a clamp. A plurality of valve openings are arranged on the cambered plates and the channel plate, and float valves are arranged in the valve openings. A downcomer plate is arranged on one side of the tower plate, a vertical beam is arranged on the other side of the tower plate, and a bending portion is arranged on the lower portion of the vertical beam.
Description
Technical field
The present invention relates to a kind of tower joint structure of industrial tower, in particular, relate to a kind of plate column joint structure of petrochemical complex tower of the purposes of imparting knowledge to students.
Background technology
Tower is one of visual plant during oil, chemical industry, medicine, light industry etc. are produced.In commercial production, the prophylactic repair tower is must be obligato, and the disassembly process that therefore can be familiar with the inner structure, principle of work of plate column and skilled grasp plate column is one of the professional skill that must grasp of relevant speciality student.
China Patent Publication No. CN1199767A discloses the gas fractionation process of the energy-conservation high yield of a kind of province's tower, specifically discloses to improve the propylene recovery, reduces equipment investment, energy consumption and operation cost.But such tower is not suitable for being applied to the purposes of imparting knowledge to students, and personnel enter the inner maintenance of tower and visit very large potential safety hazard.
In higher education and professorship education, be one of important content about plate column structure, principle, maintenance etc. in the course of Chemical Process Equipment specialty.The teaching pattern of plate column all is take the papery teaching material and visits the related industries scene as main at present, but the papery teaching material is generally more abstract tower structural representation, the student wants to see real tower structure, can only arrive the industry spot visiting and learning, but, during the general petroleum chemical enterprise equipment rebuilding, exist a lot of potential safety hazards, forbid that generally the student advances factory's visiting and learning, so, the student is difficult to have an opportunity to see the inner structure of plate column during the school, also have no chance to carry out the isostructural dismounting training of tower tray.
Summary of the invention
For problems of the prior art, carried out the improvement of tower joint structure, make it more be fit to the teaching purposes.The technical problem to be solved in the present invention is that a kind of plate column joint of tower of the purposes of imparting knowledge to students is provided.
A kind of teaching mode of plate column joint, tower tray is fraction block structure, and tower tray comprises 2 cambered plates and 1 channel plate, and channel plate is arranged between 2 cambered plates; Cambered plate circular arc one side is welded on the tower body inwall by clamp; Several valve openings are set on cambered plate and the channel plate, float valve is set in the valve opening; One side of tower tray arranges down-flow plate, and opposite side is provided with vertical beam, and the vertical beam bottom has dogleg section.
As further preferred, cambered plate is connected screw bolt and nut with channel plate and connects.
As further preferred, down-flow plate has bending structure.
As further preferred, cambered plate and channel plate all have flanging.
As further preferred, also comprise seal pot, an end of seal pot is connected on the tower body inwall.
As further preferred, seal pot arranges the reinforcement gusset near the part bottom of tower body, and seal pot is provided with the support circle away from the part bottom of tower body.。
As further preferred, cambered plate and channel plate are fixedly connected on the seal pot by screw bolt and nut.
Beneficial effect:
Safe and reliable, can allow the student enter, visit, there is not safety problem.
The student can carry out dismounting to the tower joint, strengthens the student to the understanding of tower joint structure, sharpens understanding.
On existing tower joint architecture basics, carried out tower joint architecture advances, can be fit to the purposes of imparting knowledge to students.
This teaching not only can be understood tower joint structure with the tower joint, can also simulate actual principle of work and ruuning situation.

Embodiment
As shown in Figure 1, tower body 8 is by diameter
D N=914mm, highly
H=750mm, thickness
tThe roll of steel plate weldering of=3mm forms.Tower tray is fraction block structure, for professional skills such as training of students is installed, maintenance tower trays, the plate column joint is designed to piecemeal formula tower tray.The sectional type tower tray is welded on the tower tray support member of tower body 8 inwalls by a plurality of clamps 7, and clamp 7 is arranged on circular arc one side of arc column plate 1.Tower tray is fraction block structure, and as Figure 1-3, tower tray is divided into two cambered plates 1 and a rectangular channel plate 2, and cambered plate 1 and channel plate 2 all adopt the punching press flanging, makes it have enough rigidity.
Cloth at tower tray is set up, two cambered plates 1 are positioned at both sides near the tower wall, channel plate 2 is arranged in the middle of the tower tray, understands the contact condition of biphase gas and liquid flow body medium in structural relation, principle of work and the tower body of adjacent two tower trays for the ease of the student, in a side of tower tray down-flow plate 9 has been installed.The teaching plate column of design joint both can allow the student get information about equipment configuration, the principle of work of plate column internal tray like this, can allow again the student utilize specific purpose tool to carry out the dismounting and maintenance training of tower tray.Has important teaching Practical significance.
Adopt a plurality of bolts 5 and nut 6 to connect between the flanging of cambered plate 1 and channel plate 2, guarantee to connect reliably between them, do not relatively move.Cambered plate 1 is fixedly connected with seal pot 12 with nut 4 by a plurality of bolts 3 with channel plate 2.Connect by screw bolt and nut, for easy disassembly, provide the teaching purpose of test exercise for the student.One end of seal pot 12 is fixed on the inwall of tower body 8.Also be provided with the bending spill near seal pot 12 and tower body 8 inwall junctions, be provided with in the bottom of spill and strengthen gusset 13, can effectively support, seal pot 12 is provided with support circle 11 away from the bottom of tower body.Vertical beam 10 is set falling liquid dish 9 relative tower tray one sides, vertical beam 10 bottoms have bending structure.
Teaching saves with tower, adopts float valve plate column joint, and tower tray adopts the overflow-type tower tray.Float valve is the gas-liquid mass transfer element, and the valve opening that to have several standard apertures on cambered plate and the channel plate be Φ 39mm has been installed the float valve that can fluctuate in proper range in the hole.During work, steam rises from valve opening, backs down float valve, passes the annulus, is blown into liquid layer with horizontal direction, forms foam.Float valve can be along with the increase and decrease of gas speed free adjustment, lifting in quite wide gas speed scope, thereby can adapt to the variation of larger gas phase load.The visible accompanying drawing 4 of the principle of work of tower.The structure of the technical scheme of Ben Tajie and connected mode all are to design for teaching purpose.
This embodiment just embodies the preferred special case of spirit of the present invention, those skilled in the art fully can be according to the present invention the purport of patent, in addition flexible has reached best implementation result.The present invention is made amendment or is equal to replacement, and do not break away from the spirit and scope of patent of the present invention, it all should be encompassed in the middle of the claim scope of patent of the present invention.
