The utility model has the advantages that the load-adjustable rectangular floating valve is simple in structure, convenient to use and high in mass transfer efficiency, is placed in a valve opening of a tower plate and circumferentially fixed, cannot fall off easily when in use, and enables gas and liquid in the tower plate to be contacted uniformly.
Description
Technical field
The utility model relates to a kind of rectangle float valve of deferrable load.
Background technology
In the industrial equipment tower, comparatively extensive with the plate column application, and the float valve that the gas-liquid contact element in the plate column is installed simply to make, operating flexibility is large, treatment effeciency is high is used wider.The float valve main body has valve block and valve leg, valve block be shaped as triangle, circle or rectangle, the quantity of valve leg is two or three.
At present, industrial float valve commonly used is that valve block is circular F1 type float valve.During the operation of F1 type float valve, air-flow outwards sprays around valve block, because the area of gas passage is restricted, makes gas flow rates excessive, and valve block top gas-liquid contact is bad, and pressure drop increases around the float valve, and mist entrainment is large, and mass-transfer efficiency is low; Simultaneously, because circular float valve is circumferentially unfixing, rotation produces wearing and tearing easily in operation, causes float valve to come off, thereby causes phase short circuit in the plate column, seriously reduces the column plate treatment effeciency.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of rectangle float valve of deferrable load, and this float valve is circumferentially fixing, and difficult drop-off during use can make column plate gas gas-liquid contact even, and mass-transfer efficiency is high.
Technical solution of the present utility model is:
A kind of rectangle float valve of deferrable load, the valve block that a rectangle is arranged, described valve block two ends are respectively equipped with long valve leg, short valve leg, before and after the valve block two ends, be provided with downward-sloping support arm, described long valve leg lower end and short valve leg lower end are respectively equipped with the valve pin, its special character is: the height of described long valve leg is greater than the height of short valve leg, the centre position of described valve block is provided with trapezoidal guide hole, the long base of described trapezoidal guide hole is arranged near long valve leg one side, be provided with the float valve cavity in the corresponding described trapezoidal guide hole of valve block upper surface position, the four sides of described float valve cavity is respectively equipped with the dispersion guide hole.
Side is respectively equipped with downward-sloping leg before and after the described valve block, and the minimum aperture with the restriction valve block prevents the adhesion of valve block and column plate.
Described long valve leg middle and lower part is provided with circular pod apertures, to eliminate the dead band of mass transfer, reduces gradient of liquid level.
The width of the width of described long valve leg and short valve leg is all less than the width of valve block, to avoid air-teturning mixed phenomenon.
Described trapezoidal guide hole be shaped as isosceles trapezoid.
The beneficial effects of the utility model:
(1) simple in structure, easy to use, this rectangle float valve is placed the valve opening of column plate, circumferentially fixing, difficult drop-off in use.
(2) this rectangle float valve can easy on and off floats along with the difference of gas phase load, the part air-flow enters the float valve cavity via the trapezoidal guide hole of valve face, the dispersion guide hole that is arranged by the four sides of float valve cavity sprays into the column plate liquid layer, increased the gas passage effective area, thereby reduced gradient of liquid level and column plate pressure, reduced gas velocity, made column plate gas gas-liquid contact even, reduce mist entrainment, improved mass-transfer efficiency.
(3) this rectangle float valve is when the gas phase load variations is larger, can by the valve leg float to regulate air-flow by float valve, thereby improve mass-transfer efficiency; And the height of two valve legs is different, thereby can adapt to different gas phase loads, has increased operating flexibility, has reduced the column plate resistance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the right view of Fig. 1.
Among the figure: 1-valve pin, the long valve leg of 2-, the 3-pod apertures, the 4-support arm, the 5-valve block, the trapezoidal guide hole of 6-, the 7-leg, 8-float valve cavity, 9-disperses guide hole, the short valve leg of 10-.
The specific embodiment
As shown in the figure, the rectangle float valve of this deferrable load, the valve block 5 that a rectangle is arranged, described valve block 5 two ends are respectively equipped with long valve leg 2, short valve leg 10, be provided with downward-sloping support arm 4 at valve block 5 two ends front and back positions, the width of the width of described long valve leg 2 and short valve leg 10 is all less than the width of valve block 5, to avoid air-teturning mixed phenomenon; Described valve block 5 front and back sides are respectively equipped with downward-sloping leg 7, with the minimum aperture of restriction valve block 5, prevent the adhesion of valve block 5 and column plate; Described long valve leg 2 lower ends and short valve leg 10 lower ends have been respectively equipped with valve pin 1, the height of described long valve leg 2 is greater than the height of short valve leg 10, be provided with circular pod apertures 3 in long valve leg 2 middle and lower parts, the centre position of described valve block 5 is provided with trapezoidal guide hole 6, described trapezoidal guide hole 6 long bases are arranged near long valve leg 2 one sides, be provided with float valve cavity 8 in the corresponding described trapezoidal guide hole of valve block 5 upper surfaces 6 positions, the four sides of described float valve cavity 8 is respectively equipped with and disperses guide hole 9.
During work, portion gas enters float valve cavity 8 through trapezoidal guide hole 6, by disperseing guide hole 9 to spray to the column plate liquid layer, promote liquid flow on the column plate, effectively reduce gradient of liquid level, increased the valid circulation area of gas, thereby reduced gas velocity, reduced mist entrainment, improved mass-transfer efficiency; When the gas phase load was larger, float valve upwards floated, and the circular pod apertures 3 on the long valve leg 2 is opened, and gas blows out from circular pod apertures 3, promoted the liquid flow on the column plate, and the dead band of having eliminated mass transfer has reduced gradient of liquid level; When gas phase load hour, float valve sinks, circular pod apertures 3 is closed, and no longer sprays gas, can not produce the adverse effect of blowing thin liquid layer.
