Description

Technical Field

[0001] The invention relates to a packing support for a packing tower device, in particular to a packing support with a liquid phase collecting function. Background Art

[0002] Packed towers are widely used in unit operation processes such as distillation, absorption, washing, extraction and cooling. Compared with plate towers, they have many advantages such as large flux, high efficiency, low pressure drop and small liquid holdup. Their application scope is becoming wider and wider, and the scale of the equipment is getting larger and larger. The reasonable design of the packing support plays an important role in ensuring the operating performance of the packed tower.

[0003] Conventional design of packing support adopts hump support or grid support on the upper part of steel beam. As the packing tower is enlarged, the specifications of steel beam are getting larger and larger, and the height of the packing tower is also increasing, which increases the investment cost. The liquid collector is an important component of the packing tower. Its performance also directly affects the production capacity, separation efficiency and pressure drop of the packing tower. Generally, the collecting plate is set at the bottom of the packing support. Its components are similar to the structure of the packing support and repeatedly occupy a certain height space of the packing tower. Summary of the invention

[0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a packing support with a liquid phase collection function, which combines the packing support and the liquid phase collection into one, has a compact structure, effectively reduces the tower height, has excellent fluid mechanics properties, a high porosity, is not easy to clog, and has a small pressure drop.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A packing support with a liquid phase collection function comprises a packing support ring, a collection support grid assembly, an annular collection trough and a liquid collection support beam; the packing support ring and the annular collection trough are both annular, fixed to a tower wall one above and one below, a plurality of liquid collection support beams are fixed to the inner wall of the annular collection trough, and the top is flush with the annular collection trough to form a flat support plane; the collection support grid assembly is fixed to the flat support plane, covering the entire tower cross section and the packing support ring to form a packing support; the collection support grid assembly is provided with liquid distribution holes, and the liquid distribution holes are located directly above the liquid collection support beam.

[0007] The collecting support grid assembly comprises a collecting support grid, an upper connecting plate and a lower connecting plate; a plurality of collecting support grids are connected into a strip structure through the upper and lower connecting plates.

[0008] The cross section of the collecting support grid is S-shaped, and the horizontal projections of the collecting support grid overlap each other; a liquid collecting trough is provided, and a liquid distribution hole is provided at the bottom of the liquid collecting trough.

[0009] The width and thickness of the strip structure formed by connecting the plurality of collecting support grid plates through the upper and lower connecting plates are both smaller than the tower manhole.

[0010] The cross section of the liquid collecting support beam is U-shaped, and both ends of the liquid collecting support beam are fixedly connected to the inner wall of the annular collecting groove and are communicated with the annular collecting groove.

[0011] Reinforcement plates are evenly distributed on the inner circumference of the annular collecting groove.

[0012] It also includes a liquid discharge pipe which is fixedly connected to the tower wall and communicated with the annular collecting tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1) The collecting support grid assembly of the present invention is fixedly connected to a flat supporting plane, covering the entire tower cross section and the packing support ring to form a packing support, and has both packing support and liquid collection functions, a compact structure, and effectively reduces the tower height, has excellent fluid mechanics performance, a high porosity, is not easy to clog, and has a small pressure drop.

[0015] 2) In the present invention, multiple liquid collecting support beams are fixed to the inner wall of the annular collecting tank, and the top is flush with the annular collecting tank to form a flat support plane; it has the function of collecting and merging liquid. The collecting support grid assembly collects all the liquid flowing out from the previous packing layer. Part of the liquid collected in the collecting tank of the collecting support grid assembly flows into the annular collecting tank at both ends, and part of the liquid first enters the liquid collecting support beam through the liquid distribution hole at the bottom of the collecting tank, and then merges into the annular collecting tank, and then is discharged out of the tower.

[0016] 3) The width and thickness of the strip structure formed by connecting the multiple collecting support grid plates through the upper and lower connecting plates of the present invention are both smaller than the manhole of the tower, so it is easy to install in the tower.

[0021] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0022] [Example]

[0023] like Figure 1-3As shown, a packing support with liquid phase collection function includes a packing support ring 7, a collection support grid assembly, an annular collection groove 4, a liquid collection support beam 6 and a liquid discharge pipe 8.

[0024] The packing support ring 7 and the annular collecting groove 4 are both annular, and are horizontally welded on the inner wall of the tower. The packing support ring 7 is located above the annular collecting groove 4. The drain pipe 8 is fixed on the outer wall of the tower and communicated with the annular collecting groove 4.

[0025] The cross section of the liquid collecting support beam 6 is U-shaped, and both ends of the liquid collecting support beam 6 are welded to the inner wall of the annular collecting tank 4 and communicated with the annular collecting tank 4. Multiple liquid collecting support beams 6 are parallel to each other and horizontally fixed to the inner wall of the annular collecting tank 4. The top of the liquid collecting support beam 6 is flush with the annular collecting tank 4 to form a flat support plane.

[0026] The collection support grid assembly includes multiple collection support grids 1, an upper connecting plate 2 and a lower connecting plate 3. The collection support grid 1 has an S-shaped cross section, and the horizontal projections of the collection support grids 1 overlap each other. A liquid collecting trough is provided, and a liquid distribution hole is provided at the bottom of the liquid collecting trough. The liquid distribution hole is located directly above the liquid collecting support beam 6.

[0027] Multiple collecting support grid plates 1 are connected into a strip structure through an upper connecting plate 2 and a lower connecting plate 3. The width and thickness of the strip structure are smaller than the tower manhole, so as to facilitate installation in the tower.

[0028] The collecting support grid assembly is fixedly connected to the flat support plane, covering the entire tower cross section and the packing support ring 7, forming a packing support.

[0029] The collecting support grid assembly collects all the liquid flowing out from the previous packing layer. Part of the liquid collected in the collecting support grid liquid collecting tank flows into the annular collecting tank 4 at both ends, and part of the liquid enters the liquid collecting support beam 6 through the bottom liquid distribution hole, and then flows into the annular collecting tank 4, and then is discharged out of the tower through the drain pipe 8.
