In order to solve the problems of the technologies described above, the novel anti that the utility model provides is blocked up high-efficient tower plate, comprise column plate and unsettled downflow weir, be divided into center mass-transfer zone and liquid and flow easy stagnant wake, the center mass-transfer zone is the mid portion in nearly unsettled downflow weir zone and column plate rectangular centre zone, its innovative point is, the central area of column plate is rectangular, punching press is staggered and two kinds of guiding of following current arrangement sieve apertures in rectangle, the direction of the staggered guiding sieve aperture of every row is all vertical with the liquid flow path direction, and the direction of every adjacent two row's guiding sieve apertures is opposite; The center mass-transfer zone has the guiding sieve aperture that 1-5 alignment stream is arranged, and its direction is consistent with the liquid flow path direction; The column plate both sides that liquid flows easy stagnant wake have the guiding sieve aperture that following current is arranged, and its direction is consistent with the liquid flow path direction.
The structure of the aforementioned unsettled downflow weir of the utility model is identical with the structure of the disclosed unsettled downflow weir of Chinese patent CN200920074777.7.
Preferably, in the stifled high-efficient tower plate of the aforementioned novel anti of the utility model, it is characterized in that the spacing d of every adjacent two row's guiding sieve apertures is 16-80mm; The height of guiding sieve aperture is 3-8mm, and width is that 12-56mm, punching press width are 6-30mm, and the spacing of adjacent two guiding sieve apertures is that the guiding angle of 8-46mm, guiding sieve aperture is 70-150 °, and the angle of guiding sieve aperture and plate face is 30-85 °.
Preferably, in the stifled high-efficient tower plate of the aforementioned novel anti of the utility model, the lower limb of unsettled downflow weir and the flying height between the column plate are 5-40mm, and unsettled downflow weir and column plate can the interior up-down adjustment of aforementioned as required flying height
Preferably, in the stifled high-efficient tower plate of the aforementioned novel anti of the utility model, further comprise inlet weir, the inlet weir upper punch is pressed with circular hole, and the diameter of circular hole is 4-16mm, and circular hole is wrong row's form and arranges.
The utility model compares with traditional direction sieve aperture tower tray and have the following advantages: (1) has been reduced the stagnant wake of liquid on the tower tray or has been reduced liquid in the time of staying of stagnant wake, makes the vapour-liquid contact more abundant; The efficient and the disposal ability of tower tray have been improved.(2) employing of unsettled downflow weir has increased automatically cleaning ability of the present utility model especially, has prolonged the maintenance period of tower tray.(3) up-down adjustment of unsettled downflow weir and support type downspout, overcome the little shortcoming of traditional direction sieve aperture tower tray operating flexibility, because there is the unsettled of certain altitude the below of unsettled downflow weir, be very favorable for the operating mode that impurity is arranged simultaneously, can make impurity smoothly by reducing the obstruction of tower tray, prolong the clean and maintenance cycle of tower tray.
