A spherical double-layer spiral packing

technical field

The utility model relates to a packing, in particular to a spherical double-layer spiral packing used in a coking industrial packing tower.

Background technique

In the coking industry, packed towers are often used to purify coke oven gas. Through the gas-liquid countercurrent contact in the packed tower, the liquid medium absorbs part of the substances in the gas medium, so as to achieve the purpose of purifying the gas medium. The packing in the traditional packed tower is often fixed and compacted. Due to the wall flow of the packing itself, the gas and liquid go their own way, the mass transfer efficiency is not high, and bridging and cavitation often occur. In order to meet the mass transfer effect, the packed tower is forced to be thicker and taller, resulting in an increase in liquid circulation, and a great waste of equipment investment and operating costs.

Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with accompanying drawing:

See Fig. 1, it is the structure schematic diagram of the present utility model, and a kind of spherical double-layer spiral packing of the present utility model comprises outer layer keel frame packing 1 and inner spherical spiral packing 2, and described inner spherical spiral packing 2 is surface band The sphere with spiral texture 21 can freely suspend and move in the outer keel frame-shaped filler 1 .

The outer keel frame filler 1 is a spherical frame filler with a grid structure, and the spherical frame is composed of at least three transverse ribs 11 and multiple vertical ribs 12 .

The outer keel frame filler 1 has a detachable structure, which can be split into two hemispheres along the middle transverse rib 11, and can be connected and combined through the buckle structure provided on the middle transverse rib 11.

The outer keel frame filler 1 is made of plastic.

See Fig. 2, which is a structural schematic diagram of the inner spherical spiral packing of the utility model. The inner spherical spiral filler 2 is a hollow sphere with a spiral texture 21 on the surface, and the spiral texture 21 is uniformly arranged between two symmetrical vertices of the sphere, and has the same shape and direction of rotation.

The groove depth of the spiral texture 21 is 1/20-1/10 of the outer diameter of the sphere.

The material of the inner spherical spiral packing 2 is plastic.

In the utility model, the outer keel frame-shaped packing 1 is located at the outer periphery of the inner spherical spiral packing 2, and acts as a skeleton support; the outer keel frame-shaped packing 1 has a spherical frame with a grid-like structure, and the structure shown in Figure 1 is For example, the outer keel frame filler 1 is horizontally provided with three horizontal ribs 11, and vertically provided with several vertical ribs 12, and the vertical ribs 12 are evenly arranged between the three horizontal ribs 11 to form a stable spherical frame structure. The outer keel frame-shaped filler 1 can be disassembled into two halves as required, and can be combined and connected through the buckle structure on the middle transverse rib 11, which is very convenient for disassembly and assembly.

The inner spherical spiral packing 2 is located inside the outer keel frame-shaped packing 1, and is a hollow sphere with a special spiral texture 21 on the surface; taking the structure shown in Figure 2 as an example, the surface of the inner spherical spiral packing 2 is provided with multiple shapes, The spiral textures 21 with the same direction of rotation have the characteristics of being wide in the middle and narrowing at both ends. The two end points of the spiral textures 21 meet respectively and are located on the two symmetrical vertices of the sphere.

The materials of the outer keel frame packing 1 and the inner spherical spiral packing 2 are all selected from plastic materials with low density, such as polyethylene and polypropylene.

The working principle of the spherical double-layer spiral packing of the utility model is that the outer keel frame-shaped packing 1 is fixed relative to the tower body, and the gas medium passes through the grid-shaped frame and contacts with the inner spherical spiral packing 2 . The inner spherical spiral packing 2 can freely suspend and float in the reserved space in the outer keel frame packing 1, and both inner and outer packings can play the role of gas-liquid mass transfer. The thread texture 21 on the inner spherical spiral packing 2 effectively increases the specific surface area of the packing, and at the same time, the fluid flows between the spiral textures on the packing surface, which can effectively prevent short circuit. Under the two-way impact of gas and liquid, the packing keeps turbulent, disturbing, jumping, and churning in the reserved space, so that the gas and liquid can fully and repeatedly contact in the dynamic packing, thereby greatly improving the mass transfer effect.
