Embodiment 1

[0022] The test was carried out in an experimental tower with an inner diameter of φ600mm. 3 layers of baffle plate trays of the present invention are installed in the experimental tower, and the tray spacing is 600mm. The tray of each tray is composed of 3 steps, the height h of each step is 50mm, and the width w is 100mm. The thickness of the trays was 4 mm. The overflow weir on the lowest step tray is a flat weir with a height of 40mm. Circular sieve holes are evenly opened on the tray plate of each step, the diameter of the sieve holes is φ8mm, and the opening ratio is 15.8%. The deflector is a solid plate with a thickness of 4 mm and an angle α with the tower wall of 30 degrees. The area of ​​the deflector is 1 / 4 of the cross-sectional area of ​​the tower (experimental tower).

[0023] The test medium is air-water, and the hydraulic test is carried out at normal temperature (15-28°C). The strength of the liquid flow is 60m 3 / (m h), the superficial gas velocity is 0....

Embodiment 2

[0028] The test was carried out according to the experimental device and conditions of Example 1; the difference was that the angle α between the deflector and the tower wall was 45 degrees, and the superficial gas velocity was 1.7m / s. The test results are shown in Table 2.

Embodiment 3

[0032] The test was carried out according to the experimental device and conditions of Example 1; the difference was that the angle α between the deflector and the tower wall was 60 degrees, and the superficial gas velocity was 2.6m / s. The test results are shown in Table 3.

Abstract

The invention disclosed a baffle type tray for gas-liquid mass transfer in the field of petrochemical processing to resolve the problem of low efficiency, complex structure, large investment and small processing capacity for gas-liquid mass transfer for the present float valve and baffle type tray. The tower plate (3) of the baffle type tray of the invention is composed of the down steps along the direction of the liquid flow. The sieve pore (5) or the valve orifice on which float valve is fixed are opened on each step of the tower plate (3). A oblique downwards arc skirt plate is mounted on the top of the arc where the highest step tower plate (3) intersects with the wall (1) of the tower under the tower plate (3). The invention may be used in the rectification tower, absorber, thionizer and regeneration tower, etc.

Description

technical field [0001] The invention relates to a baffle plate tray used for gas-liquid mass transfer in the field of petrochemical industry, which is used for rectification, absorption, desulfurization, regeneration and other towers. Background technique [0002] Tray tower is a kind of gas-liquid mass transfer equipment widely used in petrochemical production process. Nowadays, a type of tray widely used in plate towers is the valve tray; each layer of this type of tray contains an overflow weir, downcomer and liquid receiving tray, and the entire layer of trays is on the same plane. The gas phase is blown out from the valve hole-float valve, and is in contact with the liquid on the tray for mass transfer. Valve trays have the disadvantages of complex structure, large investment, and small gas-liquid flux. Another type of tray is the baffle tray, see Hydrocarbon Processing, September 1983 / Data for towerbaffle design and Hydrocarbon Processing, May 1993 / How to design baff...
