Description

Limiting device for tower packing

Technical Field

The utility model relates to a packing limiting rotating shaft, in particular to a limiting device for packing of a tower, and belongs to the technical field of packed towers.

Background

The packed tower has small fluid resistance and is suitable for the process with large gas treating capacity and small liquid capacity. The liquid flows down the packing surface from above and the gas is counter-current or co-current with the liquid, depending on the particular reaction. The liquid storage amount in the packed tower is smaller. The flow pattern in the column is close to plug flow, whether in the gas or liquid phase. If solid phase is generated in the reaction process, a packed tower is not suitable.

The packing tower uses packing as a basic component for gas-liquid contact and mass transfer, liquid flows from top to bottom in a film shape on the surface of the packing, gas flows from bottom to top in a continuous phase and is transferred to the liquid, and mass transfer and heat transfer between the gas and the liquid are carried out. The component concentration and temperature of the two phases vary continuously along the column height. The packed tower belongs to gas-liquid mass transfer equipment with differential contact.

The tower body of the packing tower is a vertical cylinder, the bottom of the tower body is provided with a packing support plate, and the packing is placed on the support plate in a random or integral manner. A packing pressing plate is arranged above the packing to prevent the packing from being blown by the upward air flow. Liquid is sprayed from the top of the column through a liquid distributor onto the packing and flows down the surface of the packing. The gas is sent from the bottom of the tower, distributed by a gas distribution device (the small-diameter tower is not provided with the gas distribution device generally), and then continuously passes through the gaps of the packing layer in countercurrent with the liquid, and the gas phase and the liquid phase are in close contact on the surface of the packing to carry out mass transfer. The packing tower belongs to continuous contact type gas-liquid mass transfer equipment, the composition of two phases continuously changes along the height of the tower, and in a normal operation state, the gas phase is a continuous phase, and the liquid phase is a disperse phase. As the liquid flows down the packing there is a tendency to concentrate toward the column wall, causing the flow of liquid near the column wall to increase gradually, a phenomenon known as wall flow. The wall flow effect causes uneven distribution of gas-liquid phases in the packing layer, thereby reducing mass transfer efficiency. The filler is required to be limited in the tower, so that the filler is kept at a fixed position and is prevented from moving under the pushing of liquid or gas, but the existing limiting device is inconvenient to adjust, and only specific filler can be limited, so that the device is inconvenient to use.
