Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of packing equipment for rectifying tower, and particularly relates to a packing device for rectifying tower. BACKGROUND

[0002] The rectifying tower is a tower type gas-liquid contact device for rectification. The light components (low-boiling substances) in the liquid phase are transferred to the gas phase, and the heavy components (high-boiling substances) in the gas phase are transferred to the liquid phase, so as to realize the purpose of separation, by taking advantage of the different volatility of each component in the mixture, i.e. the different vapor pressures of each component at the same temperature.

[0003] The packing layer inside the tower body is usually provided with a very high packing density and a large number of pore structures, which greatly increases the surface area, thereby improving the contact efficiency between components, promoting the mixing of liquid and gas, and guiding them to the separation layer, so as to improve the transfer efficiency.

[0004] The packing layer in the tower body is fixed on the packing support plate, and the packing support plate is fixed on the inner wall of the tower body by a plurality of bolts to complete the installation of the packing layer. Therefore, when the packing layer is disassembled for cleaning, the fixing bolts need to be removed one by one to complete the disassembly, and the bolts need to be fixed again during installation after cleaning. Not only is the operation troublesome, but also the bolts at the fixed position will be loose due to damage to the threads after several disassemblies. In view of this, a packing device for rectifying tower is designed to facilitate disassembly and installation. SUMMARY

[0005] In view of the above technical problems, the utility model provides a packing device for rectifying tower. The packing device is designed to only need to control the rotating clamping ring for disassembly and installation of the packing layer after the first bolt fixation of the fixing ring in the packing device, so as to realize convenient disassembly and installation of the packing layer.

[0006] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0007] A packing device for rectifying tower, characterized by comprising a fixing ring, a rotating clamping ring, a connecting seat, a bottom plate and a packing layer, the lower end of the fixing ring is fixed in the interior of the tower body by a plurality of bolts, the inner wall of the fixing ring is provided with an annular groove, the annular groove is matched with the annular strip provided on the outer wall of the rotating clamping ring, the annular strip of the rotating clamping ring is connected in the annular groove of the fixing ring, the upper end of the rotating clamping ring is buckled with the connecting seat, the connecting seat is sequentially provided with the bottom plate and the packing layer from top to bottom,

[0008] A plurality of positioning grooves are arranged at intervals at the upper end of the rotating clamping ring, a limiting groove is arranged on one side of the positioning groove, the positioning groove and the limiting groove are communicatively arranged, and the positioning groove and the limiting groove are integrated into an overall "L" shape structure,

[0009] The outer wall of the bottom of the connecting seat is provided with multiple groups of clamping blocks at intervals.

[0010] Specifically, the number of the clamping blocks is consistent with the number of the positioning grooves.

[0011] Further, the bottom of the rotating clamping ring is provided with an operating handle, so that the rotating clamping ring is rotated through the operating handle to complete the limiting and fixed connection of the connecting seat and the rotating clamping ring.

[0012] Further, the bottom plate is of a grid structure, which not only supports the filler layer well, but also does not affect the gas-liquid passing.

[0013] The beneficial effects of the present application are as follows:

[0014] The filler device designed in the present application is first fixedly installed on the tower body of the rectifying tower through the bolts, then the clamping blocks on the connecting seat below the filler layer are aligned with the positioning grooves on the rotating clamping ring to complete the installation and positioning of the filler layer, then the rotating clamping ring is rotated by the operating handle to make the clamping blocks move into the limiting grooves of the rotating clamping ring, that is, the installation of the filler layer is completed, when the filler layer needs to be cleaned, the rotating clamping ring is only rotated through the operating handle to make the clamping blocks on the connecting seat move out of the limiting grooves of the rotating clamping ring and into the positioning grooves, that is, the limiting and fixing of the connecting seat is released, then the filler layer is hoisted out of the tower by the hoisting equipment or the elevator, in addition to the first time when the fixed ring in the filler device needs to be fixed through the bolts, the subsequent disassembly and installation of the filler layer only need to control the rotating clamping ring, so the device is convenient to disassemble and assemble.
