Abstract

The utility model relates to the technical field of gas-liquid contact mass transfer equipment in oil refining industry, petrochemical industry and chemical industry, and provides plug-in type connection tray plates which are components used for a distillation tower and an absorption tower. Each plug-in type connection tray plate is a square plate shape component with one side provided with a protruded plug tongue and the other side opposite to the plug tongue bending downwards to form a lapping portion, wherein edges of the lapping portion bend downward to form a self-support beam. The lapping portion is provided with a plug hole corresponding to the plug tongue, and a plurality of valve holes are arranged on the tray plates. The width of the lapping portion can range from 15 to 30 millimeters. Because a connecting piece is not used in the lapping portion, the equipment cost is reduced. Two tray plates are in the same level after being installed and the position of lapping place has no protrusion, and therefore the mass transfer efficiency and the processing capacity can be improved, the difficulties in installation and operation are simplified, and the working efficiency is improved.

Description

A kind of plug-in type connects tray deck

Technical field

The utility model relates to gas-liquid the contact mass transfer equipment technical field, particularly destilling tower in oil refining, petrochemical industry, the chemical engineering industry, the parts on absorption tower.

Background technology

The tower tray of chemical tower is divided into made of one piece and sectional type, when tower diameter is 300-800mm, adopts made of one piece; Tower diameter adopts sectional type during greater than 800mm, and the sectional type tower tray is mutually permanently connected by the polylith tray deck; Splicing becomes the tower tray on destilling tower, absorption tower, and shown in Figure 3 is a kind of tray deck of prior art, and it is to be fixedly connected by each adjacent two tray deck to combine; The binding end 9 of last tray deck 11 is pressed in down tray deck 8 to have above strutbeam 3 one sides; The two uses connector 10 to connect, and connector 10 can adopt bolt, clamp, wedge card etc., and what show among the figure is bolt.Its shortcoming is: need a lot of connectors 10; Connector 10 occupies tower tray part area, makes the valve body spacing widen, and reduces the bubbling area area, reduces production capacity and mass-transfer efficiency; Increase equipment cost, fitting operation is time-consuming.

The utility model content

The purpose of the utility model is to provide a kind of plug-in type to connect tray deck, does not use connector in lap-joint, reduces equipment cost, improves mass-transfer efficiency and disposal ability, simplifies the fitting operation difficulty, increases work efficiency.

To achieve these goals, the technical scheme of the utility model is:

A kind of plug-in type connects tray deck, and it is square plate-shaped member, Yi Bian have the tongue of protrusion; Its relative another side bending downwards becomes clinch, and the clinch edge bends downwards, forms from strutbeam; Clinch has the jack corresponding with tongue, has most valve openings on the tray deck.

The clinch width is 15-30mm.

Because after adopting such scheme, the utility model in use as long as adjacent another piece plug-in type of tongue insertion of a plug-in type connection tray deck is connected in the jack of tray deck, makes this side of tray deck be pressed in clinch; Can accomplish the connection operation, overlap joint back two boards is on same horizontal plane, and lap-joint does not have convexity; Saving of work and time, and practiced thrift a large amount of connectors, saved equipment investment; Because the position of having omitted connector, the more quantity of reasonable optimizing valve opening and position are to improve whole mass transfer technological effect; This tray deck can adopt Sheet Metal Forming Technology to realize that manufacturing process is simple during fabrication, and production cost is low.

1. first tray deck, 2. valve opening, 3. from strutbeam, 4. jack, 5. tongue, 6. second tray deck, 7. clinch 8. descends tray deck, 9. binding end, 10. connector, tray deck on 11..

The specific embodiment

Below in conjunction with Figure of description the specific embodiment that a kind of plug-in type of the utility model connects tray deck is further described.

It is square plate-shaped member that the plug-in type of the utility model connects tray deck, has valve opening 2 on the plate, one side its tongue with protrusion 5; Its relative another side bending downwards becomes clinch 7, and clinch 7 width can be 15-30mm, and the back upper surface is a plane so that tray deck and another tray deck are pegged graft; These clinch 7 edges are bent to form downwards from strutbeam 3; Clinch 7 has the jack 4 corresponding with tongue 5, has most valve openings 2 on the tray deck, supplies to install valve body and uses.

Fig. 1 is that two plug-in types connect tray deck joint portion cutaway view; The tongue that one side had 5 of first tray deck 1 inserts in the jack 4 of second tray deck, 6 correspondence positions; One side of the tongue 5 that first tray deck 1 has just in time is pressed in clinch 7 positions, makes that two tray deck upper surfaces are concordant, and the bending downwards of the edge of clinch 7 is from strutbeam 3; Be spliced into whole tower tray to support the polylith tray deck, have valve opening 2 on each piece tray deck and come the device valve body.

Fig. 2 is two plug-in type tray decks self shape and is in Status view to be connected; The tongue 5 of first tray deck 1 is aimed at and is not inserted as yet in the jack 4 of clinch 7 of second tray deck 6, and the shape structure of each piece tray deck can be shown, and splicing order between the tray deck; Can save the connector 10 of prior art when overlapping through the tray deck of such design; Be to connect between part realization plate, practiced thrift equipment investment cost, make that also step is simpler, convenient, firm when the splicing tower tray through tray deck itself; And the connector 10 that reduces prior art can be vacateed the position and makes the valve opening setting more reasonable; Increase the effective contact zone of gas-liquid area, eliminate liquid and walk short-circuit state, improve tray deck mass-transfer efficiency and production capacity.The plug-in type of the utility model connects tray deck and can use sheet material to adopt Sheet Metal Forming Technology production, and technology is simple, can make in batches.

Claims

1. a plug-in type connects tray deck; Have most valve openings on the tray deck, it is characterized in that: it is for square plate-shaped member, Yi Bian have the tongue of protrusion; Its relative another side bending downwards becomes clinch; The clinch edge bends downwards, forms from strutbeam, and clinch has the jack corresponding with tongue.
