Description

Technical Field

[0001] The utility model relates to the field of machinery, in particular to the technical field of mechanical parts, and specifically refers to a bubble cap tower plate of a rotary bubble cap. Background Art

[0002] The bubble cap tray is a common mass transfer device, mainly used in plate towers. Its working principle is that the liquid flows from top to bottom onto the tray, and the gas moves upward from the bottom, comes out at the bubble cap, and evenly transfers mass with the liquid.

[0003] The tower body is equipped with multiple layers of horizontal bubble cap trays, each of which is mainly composed of trays, overflow weirs, and bubbles. Each tray is provided with a number of holes for steam (or gas) to pass through, each hole is welded with a riser, and a bubble cap support frame is provided on the top of each riser. The bubble cap is fixed to the top of the riser through the bubble cap support frame. There are many tooth gaps around the lower part of the bubble cap, which are generally triangular, rectangular or trapezoidal.

[0004] Traditional bubble trays have the advantages of sufficient contact between gas and liquid phases and large mass transfer area; large operating flexibility and the ability to maintain high efficiency when the load varies over a large range; high production capacity and suitability for large-scale production; not prone to clogging, wide range of media adaptability, and stable and reliable operation. However, they are prone to form excessive foam, thus ensuring tray efficiency. Utility Model Content

[0005] The utility model aims at the deficiencies of the prior art and provides a bubble cap tray with a rotary bubble cap, which can remove the foam by driving the bubble cap to rotate through airflow, thereby ensuring the tray efficiency.

[0006] The utility model is realized through the following technical scheme: a bubble cap tower plate of a rotary bubble cap, comprising an air riser located on the tower plate, and a bubble cap covered on the air riser, the air riser is connected to a support frame rotatably connected to the bubble cap, the bubble cap is also provided with a plurality of air holes arranged along the circumferential direction, and blades corresponding to the air holes are provided on the outer circumferential surface of the bubble cap.

[0007] When the utility model is in use, gas flows out through the air holes and hits the blades, thereby driving the blades and the bubble caps to rotate, thereby realizing the rotation of the bubble caps, thereby ensuring the efficiency of the bubble cap tray.

[0008] Preferably, the blades are tilted to cover the air holes.

[0009] In this preferred solution, the blades are tilted so that the gas in the air holes drives the blades to rotate.

[0010] Preferably, the air vent is in the shape of an isosceles trapezoid, two parallel sides of the isosceles trapezoid are arranged circumferentially, and the connection between the blade and the bubble cap is close to the longer parallel side of the isosceles trapezoid.

[0011] When this preferred solution is in use, the closer the blade is to the bubble, the closer the distance to the bubble is, and the greater the impact force of the gas is. By setting the shape of the air holes, the air flow channel far from the blade is blocked, so that more gas is blown onto the bubble more quickly, increasing the impact intensity of the gas on the blade, and further enhancing the defoaming effect.

[0012] Preferably, the support frame is also provided with a bolt which penetrates upward through the bubble cap, the axes of the bolt, bubble cap and air riser are arranged in a colinear line, a nut located above the bubble cap is threadedly connected to the bolt, and a gasket is provided between the nut and the bubble cap.

[0013] In this preferred solution, the rotation of the bubble cap on the support frame is achieved by arranging bolts, nuts and washers.

[0014] Preferably, a reinforcing plate is fixed to the blister, and the bolt passes through the reinforcing plate and the blister in sequence.

[0015] In this preferred solution, the strength of the bubble cap at the bolt is enhanced by providing a reinforcing plate.

[0016] Preferably, the support frame includes a cross beam through which bolts pass, and two side beams connected to the cross beam, and the two side beams are connected to the riser.

[0017] This preferred solution realizes the connection between the support frame and the riser by setting the cross beam and the side beam.

[0018] The beneficial effects of the utility model are as follows: gas flows out through the air holes and hits the blades, thereby driving the blades and the bubble cap to rotate, thereby realizing the rotation of the bubble cap, thereby ensuring the efficiency of the bubble cap tower plate; the blades are tilted so that the gas in the air holes drives the blades to rotate; the closer the blades are to the bubble cap, the closer the distance to the bubble cap is, the greater the impact force of the gas is; the shape of the air holes is set to block the air flow channel far from the blades, so that more gas is blown onto the bubble cap more quickly, thereby increasing the impact strength of the gas on the blades and further enhancing the defoaming effect.
