Detailed Description
the technical solution of the present invention will be further described in detail with reference to the following examples.
The utility model discloses a semicircle sprays overflow formula column plate is adapted to gas absorption or liquid-liquid separation in-process, is the device that improves the even contact of gas-liquid. The tower plate comprises a tower plate body 1, a plurality of semi-arc nozzles 2 and a plurality of air guide holes 3, wherein one end of the tower plate body 1 is connected to the inner wall of the tower body through a bracket 5, the other end of the tower plate body is provided with a crescent downcomer 4, the semi-arc nozzles 2 are uniformly arranged on the tower plate body 1, and the semi-arc nozzles 2 are circumferentially and uniformly arranged on the semi-arc nozzles 2, as shown. The contact position of the tower body 1 and the semi-arc spray head 2 is communicated, and the gas guide holes 3 are arranged so that rising gas in the tower body can be uniformly contacted with liquid above the tower plate body 1, so that gas and liquid are uniformly mixed in a crossed manner. Preferably, the number of the semi-circular spray heads 2 is 3-7, and the semi-circular spray heads are uniformly distributed on the tower plate body 1. The number of the air guide holes 3 is 4-12, and the air guide holes are circumferentially and uniformly distributed on the semi-arc nozzle 2, as shown in fig. 2 and 3.
The utility model discloses a semicircle sprays overflow formula column plate along the vertical even tower body of locating in, and adjacent column plate cross arrangement, crescent downcomer 4 left and right sides cross arrangement on the adjacent column plate promptly to can make liquid flow to adjacent next column plate body 1 in through crescent downcomer 4. The upper end of the crescent downcomer 4 is higher than the tray body 1 to form an overflow weir, a certain liquid level is arranged on the surface of the tray body 1, and the lower end extends to the space between the tops of the adjacent next tray body 1 and the semi-arc nozzle 2, so that the phenomenon of short circuit caused by gas is avoided. Preferably, the upper end of the crescent-shaped downcomer 4 is 10-15mm higher than the tray body 1. The distance between the lower end of the crescent downcomer 4 and the adjacent next tower plate body 1 is 5-8 mm. When the utility model is used, the glass wool packing is adopted to fill the tower plate and the inner wall of the tower body tightly, thereby avoiding liquid leakage or air leakage.
The working principle is as follows: liquid in the tower transversely flows along the tower plate body 1, uniformly contacts with gas rising in the tower body through the gas guide holes 3 on the semi-circular spray head 2, and then flows to the adjacent lower tower plate body 1 along the crescent downcomer 4 at one end, so that gas-liquid mass transfer is realized.
