The purpose of this utility model is achieved through the following technical solutions:
On column plate, open the rectangle air rising hole, calotte is housed above air rising hole, between calotte and the column plate space is arranged.The bottom of calotte has mixed plate, and mixed plate is bending obliquely in cover body.The top board of calotte is two-layer up and down, and lower floor top board both sides have a baffle plate respectively, and the centre is a gas passage.The upper strata top board is short than lower floor's top board, and there is the flanging of downward bending on top board both sides, upper strata.Leave the space of certain distance between the 2-ply upper board, so that gas-liquid separation.Have 1～5 on the jet tray of calotte both sides and spray seam, injection is sewed on and is had downward-sloping deflector.
The width of air rising hole is 30mm～100mm, and length is 100mm～300mm.Space between calotte and the column plate is 5mm～30mm.The length of mixed plate is 0～30mm, with the angle of horizontal plane be 10 °～60 °.The middle air flow passage length of calotte lower floor top board is 1/4～2/5 of an air rising hole length, the length of calotte upper strata top board is 1/2～4/5 of air rising hole length, vertical range between the calotte 2-ply upper board is 20mm～60mm, and the upper strata top board flanging width of bending downwards is 0～30mm.The width that seam is sprayed in the calotte both sides is 0～40mm, and the deflector of calotte both sides and the angle of horizontal plane are 0 °～90 °.
The utility model compared with prior art has following advantage:
1. gas-liquid mixture can spray simultaneously from spraying seam and top passageway, and airflow smooth helps the raising of disposal ability and the reduction of plate pressure drop, has improved the operation upper limit.
2. the deflector and the upper strata top board flanging that spray seam can impel the oblique ejection down of gas-liquid mixture, and the liquid that has suppressed like this between the calotte liquidates, and has suppressed entrainment, helps to operate the raising of the upper limit.
3. the mixed plate of calotte bottom can impel liquid to the calotte center flow, strengthens the gas-liquid mixed effect, improves gas-liquid mass transfer efficient.

Fig. 2 is the arrange schematic diagram of jet tray in tower according to the utility model proposed;
Fig. 3 is the side structure schematic diagram according to the jet tray that the utility model proposed.
Wherein, 1-tower wall, the 2-column plate, the 3-downspout, crack at the bottom of the 4-, the 5-mixed plate, the 6-deflector, 7-sprays seam, 8-baffle plate, 9-gas channel, 10-upper strata top board, 11-upper strata top board flanging, 12-top stream passage, 13-air rising hole, 14-calotte
The specific embodiment:
Describe the concrete structure of the jet tray that proposes according to the utility model in detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, horizontal column plate 2 and downspout 3 are housed in tower wall 1, have air rising hole 13 on the column plate 2, calotte 14 is equipped with in the top of air rising hole 13, leaves crack, the end 4 between calotte 14 and the column plate 2.Calotte 14 is rectangular or trapezoidal, and the top board of calotte 14 is two-layer up and down, and lower floor top board both sides have a baffle plate 8 respectively, and the centre is a gas passage 9.Upper strata top board 10 is a blind plate, and there is flanging 11 top board 10 both sides in upper strata.Be top stream passage 12 between upper strata top board and the lower floor's top board.Calotte 14 bottoms have mixed plate 5.There is the seam of injection 7 calotte 14 both sides, and spraying seam 7 upper punches has downward-sloping deflector 6.
Jet tray arranging as shown in Figure 2 in tower.
Operation principle of the present utility model is: liquid flows down from the downspout 3 of last layer column plate, gas enters in the calotte 14 by air rising hole 13 from the below of column plate, when in gas enters calotte 14, rising, liquid crack 4 at the bottom of the calotte is sucked in the calottes, and be ground into drop by gas.The bottom of calotte 14 has mixed plate 5, can impel gas-liquid mixed to flow to calotte 14 center flow, strengthens the gas-liquid mixed effect, improves gas-liquid mass transfer efficient.Gas-liquid mixed stream is by the 12 oblique ejections down of the gas channel between calotte 14 both sides injection seam 7 and the 2-ply upper board.The multi-channel structure of the utility model design makes gas flow more smooth and easy, has improved disposal ability, has reduced plate pressure drop.Deflector 6 can impel the oblique ejection down of gas-liquid mixture with upper strata top board flanging 11, has effectively prevented entrainment, has improved mass-transfer efficiency.
The experiment proved that: when identical liquid handling amount, the plate pressure drop of this jet tray reduces about 20% than New Vertical Sieve Tray, entrainment reduces about 30%, mass-transfer efficiency improves 3%～5%, be a kind of high flux column plate of excellent combination property, can be widely used in gas-liquid mass transfer and heat-exchange apparatus in the petro chemical industry.
