This preferred scheme is through the setting of half U type bolt, when supporting the cover body, guarantees the cover body and the setting of gas lift pipe coaxial line to guarantee that steam is discharged from the circumference of the cover body fast.
Preferably, a gap is arranged between the bottom end of the cover body and the tower plate, and the distance between the top end of the cover body and the tower plate is 10-15 times of the height of the gap.
The arrangement of the preferred scheme ensures that the distance between the bottom end of the cover body and the tower plate is closer, thereby ensuring that the airflow basically flows out through the Venturi hole, and being convenient for the high-efficiency formation of bubbles.
The application of the Venturi hole on the arc wall of the cover body of the bubble cap tray.
The invention has the beneficial effects that: the steam leaves the cover body from the Venturi hole of the cover body, and due to the conical arrangement of the Venturi hole, when the steam passes through the Venturi hole, the airflow is thinned from thick to thin, so that the gas flow rate is accelerated, more bubbles are formed, the contact area is increased, the operation elasticity is large, and the high efficiency can be kept in a larger load variation range; the production capacity is high; the liquid-gas ratio range is large; the filter is suitable for various media and is not easy to block; the operation is convenient, stable and reliable; through the arrangement of the cylindrical section, the extension length of the circular table section is reduced, so that the processing of a Venturi hole is facilitated; through the arrangement of the half U-shaped bolts, the coaxial arrangement of the cover body and the riser is ensured while the cover body is supported, so that the rapid discharge of steam from the circumferential direction of the cover body is ensured; the lower end of the cover body and the tower plate are arranged relatively close to each other, so that the airflow basically flows out through the Venturi hole, and the bubbles can be formed efficiently.
