Abstract
The utility model discloses an efficient large flux floating valve tower plate, comprising a floating valve and a tower plate. The floating valve is composed of a valve cover, a front valve leg and a back valve leg. The valve cover is provided with a ridge with a tongue hole on the side along the liquid flow direction. The tongue hole of the ridge is also provided with a tongue sheet in parallel with the surface of the tower plate. The tongue hole is semicircular, and the ridge is triangle-shaped. The side face of the ridge is provided with a through opening, and the front valve leg in consistence with the liquid flow direction is provided with a diversion hole. The utility model is an efficient large flux floating valve tower plate. The valve cover of the floating valve is provided with a ridge with the tongue hole and the tongue sheet to guide the flow of the liquid, which can reduce the entrainment and further improve the upper limit of the load and the speed of the mass transfer.
Description
Technical field
The utility model relates to a kind of chemical industry valve plate.
Background technology
Valve plate is widely used in fractionating column in the industries such as oil refining, chemical industry, petrochemical industry and light industry, absorption tower, desorber, scrubbing tower, stripper etc.
Valve plate is the column plate pattern that is most widely used, and used float valve mainly is circular (F1 type valve plate) and rectangular valve.These two kinds of float valves exist common weak point and are: column plate is little to the flux of gas, liquid load, and the liquid flow on the column plate is not had guide functions, and mass-transfer efficiency is on the low side.Along with the expansion of oil refining scale, require to have a kind of column plate substituting of efficient, big flux.
Summary of the invention
The purpose of this utility model is to provide a kind of efficient big flux valve plate.It is a kind of efficient big flux valve plate, and the float valve valve gap is provided with protuberance, and protuberance is provided with tongue hole and tongue piece, and guiding liquids flows, and to reduce entrainment, further improves the upper load limit and the mass-transfer efficiency of column plate.
The purpose of this utility model is achieved in that
A kind of efficient big flux valve plate comprises float valve and column plate, and float valve comprises valve gap, preceding valve leg, back valve leg, is provided with protuberance above the valve gap, and the direction along liquid stream on the protuberance simultaneously has the tongue hole.
Also be provided with tongue piece on the tongue hole on the protuberance.Tongue piece is parallel with tray surfaces.The tongue hole is semicircle.Protuberance is triangle.The side of protuberance has port.Be provided with pod apertures with the preceding valve leg of the consistent side of liquid flow path direction.
The utility model has following advantage and good effect:
Efficient big flux valve plate has not only increased the disposal ability of gas-liquid, and the tongue hole, the tongue piece that swell port on the valve gap and swell, pod apertures on the valve leg has also promoted the abundant contact of gas-liquid in addition, has strengthened mass transfer effect, thereby has promoted the efficient of column plate.The utility model is specially adapted to existing tower is improved the transformation of disposal ability and the tray designs of Large Towers.
The data such as pressure drop, leakage, entrainment, efficient, gradient of liquid level of the utility model and F1 type float valve under equal experiment condition, have been tested respectively.
Test result shows: under normal operating condition, the utility model column plate is than the low 320Pa of the pressure drop of F1 type float valve, leakage rate reduces by 46.3%, entrainment reduces by 39.8%, efficient improves 15.2%, gradient of liquid level reduces by 86.2%, and disposal ability promotes 39.8%, and operating flexibility is also corresponding has simultaneously improved 27.1%.

The specific embodiment
Describe the utility model in detail below in conjunction with drawings and Examples.
As Fig. 1, Fig. 2, shown in Figure 3, have port 12 above the efficient big flux float valve valve gap 4, port is provided with tongue hole 5 and tongue piece 6, tongue hole and tongue piece can be gone out on valve gap in the protuberance by the punching press one-shot forming, and washing semi-circular hole open is the tongue hole, forming halfround bar slice simultaneously is tongue piece, the top in tongue hole is a straight flange, and tongue piece is along this straight flange turnover, and is parallel with the upper surface of valve gap; Valve leg 9 and back valve leg 14 before being provided with below the valve gap, two valve legs are loaded in the valve opening 10 on the column plate 1, after float valve is opened, valve gap is parallel with column plate, on the one hand, the air-flow that is blown out by 5 places, tongue hole of the pod apertures 2 of preceding valve leg and valve gap upper port front side is consistent with the liquid main flow direction to become the superposing type guiding liquids to flow, and reduces the gradient of liquid level on the column plate, improves hydrodynamics and mass-transfer performance; Two waists 3 of valve gap curve a α angle downwards, and 10 °＜α＜65 °, change gas flow pattern to reach when operating, form strong gas-liquid turbulence, gas-liquid contact closely, thus reach the purpose of strengthening mass transfer; Have narrow slit breach 8 on the valve leg, respectively there are two pairs of valve foots 7 and 13 end of two valve legs, valve foot and valve gap long axis direction be β in an angle, 0 °＜β＜65 °, one end of valve gap dashes downwards two salient points 11, and when valve gap dropped to extreme lower position, the salient point on the valve gap contacted with the upper surface of column plate, the upper surface of two waists of valve gap and column plate has a minimum aperture like this, to prevent that valve gap and column plate from killing or it is dead to glue.On the other hand, air-flow also can blow out from the port both sides that valve gap swells except that from the valve gap both sides blow out, and the so just gas-liquid contact of the multiple layer of formation reaches with lasting the gas-liquid contact and strengthens, thereby further strengthens mass transfer effect.In such cases, none flow dead of all around of float valve, and make tower inner transmission matter zone form the contact of multiple layer gas-liquid, and strengthened mass transfer effect greatly, improved plate efficiency.Because the air-flow that blows out from pod apertures and tongue hole is a level, also greatly reduce the entrainment that is produced in the gas-liquid contact process, and entrainment has exactly determined the upper limit of the disposal ability of tower, so just promoted the treating capacity of tower naturally.
As shown in Figure 4, the direction of arrow is represented the liquid flow path direction among the figure, in certain experiment tower 15 column plate 1, seal pot 16, downflow weir 17 and chord downcomer 18 is installed.Have evenly distributed valve opening 10 on the column plate 1, efficient big flux float valve of the present utility model is installed on the valve opening, the valve leg that has pod apertures points to downflow weir and downspout.
