Abstract
The utility model of an elongated float valve tray discloses a tower device for separating process in chemical industry and light industry. The utility model of a of elongated float valve tray comprises an elongated float valve, a support and a tower tray, wherein the surface of the long strands style floating valve is opened two circular sieve holes and a square or a rectangular tongue hole to increase the operational flexibility as much as possible and to increase the uniformity of fluid distribution on the complete tower tray, thereby having both the advantage of high operational flexibility of tower trays with floating valves and the advantage of large air communicating quantity of tower trays with tongue holes. Meanwhile, the notch of the tongue hole has a direction to ensure the uniformity of fluid distribution on the complete tower tray. The utility model has the advantages of reducing pressure fall of the tower tray, increasing treating capability of the tower tray, and improving efficiency of the tower tray, decreasing device investment and operational cost at the same time.
Description
Technical field
The utility model belongs to industries such as oil refining, chemical industry, light industry, adopts the technical field of tower tray as separation equipment.More particularly, be the distillation that is used in oil refining industry, absorb, take off the gas-liquid contact element of mass transport processes such as suction, stable, extraction, belong to the tower class trim apparatus of the separation process of chemical industry and light industry.
Background technology
Tower tray as mixture separation capital equipment through the development of more than 100 years (particularly nearly 50 years), can be divided into bubble cap tray, sieve aperture tower tray, tongue hole tower tray, float valve tray four big classes basically.Bubble cap tray has the little advantage of liquid phase load lower limit, but cost is higher, the installation and maintenance complexity.The tower tray that at present progressively is other form replaces.The sieve aperture tray structure is simple, easy to maintenance, the low cost of manufacturing, but liquid phase load lower limit is little, and operating flexibility is littler than bubble cap tray.
Tongue hole tray structure is simple, make easy to maintenance, low cost, and treating capacity is big, but tower diameter too very much not uses less than 1 meter tower wall effect, and the gas phase load can not be too little in addition, and the incompatibility low gas velocity is operated.Float valve tray is simple in structure, easy for installation, and operating flexibility is bigger than bubble cap tray, sieve aperture tower tray, jet tray, often use in the industry, but relative sieve aperture tower tray of its gas phase flux and tongue hole tower tray is less.For satisfying complicated production operation, design a kind of advantage that had both had above tower tray concurrently, avoid the shortcoming of above tower tray again; Just both had the function of float valve tray, sieve aperture tower tray and tongue hole tower tray concurrently, it is little to have the tower tray pressure drop again, and the new tower plate of the characteristics that the gas phase flux is big is very significant.At present domestic have multinomial patent separately on float valve and tongue hole tower tray, but by new patent searching and analysis, confirm structure with all in essence different are arranged in shape with the present invention.
The utility model content
The purpose of this utility model just is to design that a kind of to have the float valve tray operating flexibility concurrently big, tongue hole tower tray and the big advantage of sieve aperture tower tray gas phase flux, and tongue hole opening has directionality simultaneously, can guarantee the uniform novel strip float valve tray of liquid distribution on the tower tray.
In order to achieve the above object, the technical solution adopted in the utility model is: the utility model strip float valve tray comprises strip float valve, support member and column plate, for increase the operating flexibility of tower tray as far as possible, improve the uniformity of liquid distribution on the whole tower tray simultaneously, strip float valve surface has two place's round sieves and square or rectangular tongue hole, a place.Can have the big advantage of float valve tray operating flexibility like this concurrently, can have the big advantage of tongue hole tower tray gas phase flux again concurrently, tongue hole opening has directionality simultaneously, can guarantee that liquid distribution is even on the tower tray; So both can take into account big tower tray gas flux, can take into account big fluid flow again, can reduce the tower tray pressure drop, improve the disposal ability of tower tray.
The diameter of described two round sieves is 6～8 millimeters, and the minor face in tongue hole is 5～7 millimeters, and long limit is 5～9 millimeters; The uniform perforate on float valve of tongue hole and two round sieves; The perforate direction in tongue hole is 15～35 degree directions along liquid stream, can play making on the tower tray liquid flow rate even, reduces the effect of the liquid entrance liquid level discrepancy in elevation on the tower tray, can improve the efficient of tower tray, reduces equipment investment and operating cost.
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
Description of drawings
Fig. 1 is the elevation of a kind of strip float valve tray of the utility model
Fig. 2 is the vertical view of a kind of strip float valve tray of the utility model
The specific embodiment
As depicted in figs. 1 and 2, a kind of strip float valve tray of the utility model comprises strip float valve 1, support member 2 and column plate 3, and strip float valve 1 surface has two place's round sieves 4 and square or rectangular tongue hole, 5, one place 6.Round sieve 4 and 5 diameter r1 are 6～8 millimeters; The minor face j in tongue hole 6 is 5～7 millimeters, and long limit g is 5～9 millimeters; It is 15～35 degree directions that the perforate direction in tongue hole 6 becomes the β angle along liquid stream; Tongue hole 6 and two round sieves 4 and 5 are pressed tongue centerline hole and the uniform perforate of extended line symmetry thereof on float valve.
Embodiment:
As depicted in figs. 1 and 2, perforate a * the c of the column plate 3 of strip float valve tray is 48 * 25 millimeters, the length b=57 millimeter of strip float valve 1, width d=31 millimeter, opening g * the j in a tongue hole 6 is 6 * 6～6 * 8 millimeters, and it is 30 ° of directions that tongue hole 6 perforate directions become the β angle along liquid stream, and two round sieves 4 and 5 diameter r1 are 6～8 millimeters, directional angle α is 30 °, rectangular opening location dimension e is 11～13 millimeters, and circular port location dimension f is 8～9 millimeters, and the high h of float valve leg is 14.5mm.
Result of calculation shows, compares aforesaid the utility model strip float valve tray with conventional F1 float valve:
The treat liquid load can increase 20～30%,
Handle gas load and can increase 20～30%,
The tower tray pressure drop can reduce 15～25%,
Tray efficiency can increase 20～30%.
