Description
Technical Field
The utility model relates to the field of chemical industry, in particular to a supporting plate of a packed tower.
Background
The packed tower is also called as packed tower, and is one kind of common mass transfer apparatus for chemical and environment protection production. A packed column generally comprises a cylindrical column body; the tower body is filled with filler which is used as a basic component for gas-liquid contact and mass transfer and is used for increasing the contact surface between two fluids. Specifically, the method comprises the following steps: the liquid is sprayed on the packing from the top of the tower through a liquid distributor and flows down along the surface of the packing. Gas is fed from the bottom of the tower, and continuously passes through the gaps of the packing layer in a countercurrent manner with liquid, and gas-liquid two phases are closely contacted on the surface of the packing layer for mass transfer. Therefore, in order to ensure that the filler is at a proper height, a bearing plate is arranged in the packed tower to support the filler. The bearing plate needs to have certain structural strength, and meanwhile, holes are formed in the surface of the bearing plate to achieve contact between gas and filler. The support plate used in the prior art has the following problems: when the supporting plate trompil is intensive, the bulk strength of plate body can't satisfy the support needs, when the supporting plate aperture ratio is lower, can gather the liquid layer of take the altitude on the supporting plate surface, leads to the gas-liquid to smuggle secretly, leads to too early emergence flooding in the support zone, has reduced the work efficiency of packed tower. Therefore, it is a need for those skilled in the art to develop a novel supporting plate structure to achieve both the structural strength and the aperture ratio of the supporting plate.
SUMMERY OF THE UTILITY MODEL
The utility model provides a supporting plate of a packed tower, which can avoid gas-liquid entrainment and flooding in a supporting area on the premise of ensuring the structural strength and improve the working efficiency of the packed tower.
The technical scheme is as follows:
a packed tower support tray, comprising: the bottom plate is used for being fixed on the inner wall of the tower body of the packed tower; the bottom plate comprises a plurality of horizontal plates and a plurality of circular arch modules, and the horizontal plates and the circular arch modules are arranged on the bottom plate in a staggered manner; a circular hole is formed in the horizontal plate; the circular arch module comprises a circular arch plate and two semicircular side plates; the inclined plane of the circular arch plate is provided with an elliptical hole.
By adopting the technical scheme: the bottom plate is provided with the round arch modules which are distributed in a staggered manner, so that the water passing holes and the air passing holes are distributed in a staggered manner. Wherein, the gaseous phase sprays to the packing layer through the oval hole of dome module side, and the liquid phase then flows downwards through the circular port on the horizontal plate, makes the gas-liquid unblocked, and distributes evenly, avoids carrying each other between the gas-liquid, has promoted and has allowed the gas-liquid flux.
Preferably, in the packed tower support plate: and reinforcing ribs are arranged at the bottom of the bottom plate.
By adopting the technical scheme: the reinforcing ribs further improve the overall strength and rigidity of the bottom plate.
More preferably, in the packed tower support plate: a plurality of oval holes are formed in the circular arch-shaped plate, and the oval holes are distributed on the inclined plane of the circular arch-shaped plate in a staggered mode.
By adopting the technical scheme: the air passing area on the circular arch plate is increased, and the air distribution on the circular arch plate is more uniform.
More preferably, in the packed tower support plate: a plurality of circular holes are formed in the horizontal plate, and adjacent circular holes are arranged at equal intervals.
Still more preferably, in the packed tower support plate: the bearing plate of the packed tower is made of metal or plastic materials.
Still more preferably, in the packed tower support plate: the bearing plate of the packed tower is integrally formed by adopting an injection molding method.
The utility model has simple structure and is easy to realize. Compared with the prior art, the following technical progress is achieved:
(1) the rigidity is better, and the allowable load is larger;
(2) the filler particles or fragments are not easy to block the orifices;
(3) the pore distribution is more uniform and reasonable, which is beneficial to the uniform distribution and mixing of the gas.

The correspondence between each reference numeral and the part name is as follows:
1. a base plate; 2. a horizontal plate; 3. a dome-shaped module; 4. reinforcing ribs; 21. a circular hole; 31. a circular arch plate; 32. a semicircular side plate; 33. an elliptical hole.
Detailed Description
Examples 1 of the present application are shown in fig. 1-3:
a packed tower support tray, comprising: the bottom plate 1 is used for being fixed on the inner wall of the tower body of the packed tower; the material is metal or plastic, and the material is integrally formed by an injection molding method.
The bottom plate 1 comprises a plurality of horizontal plates 2 and a plurality of circular arch modules 3, and the horizontal plates 2 and the circular arch modules 3 are arranged on the bottom plate 1 in a staggered manner;
wherein, each horizontal plate 2 is provided with a plurality of circular holes 21, and the adjacent circular holes 21 are arranged at equal intervals; the aperture of the circular hole is 1-2 cm.
Each of the dome-shaped modules 3 includes a dome-shaped plate 31 and two semicircular side plates 32; the inclined plane of the circular arch plate 31 is provided with a hole group consisting of 3 elliptical holes 33; and 3 elliptical holes 33 in the same group are staggered in parallel.
