Disc spraying device

Abstract

The invention discloses a disc spraying device. The device comprises a supporting part arranged in the inner wall of a tower body, a distribution disc is arranged on the supporting part, through the supporting part, the distribution disc is placed on the center of the tower body, a vertical liquid inlet pipe is arranged on the distribution disc, and is connected with a transverse liquid inlet pipe, multiple evenly-distributed overflow pipes are arranged at the position, on the periphery of the vertical liquid inlet pipe, of the distribution disc, the tops of the overflow pipes are lower than the height of the outer edges of the distribution disc, and the overflow pipes are spraying channels with liquid sprayed to padding. Liquid is evenly distributed, and is relatively concentrated to thecenter of a tower, liquid is prevented from flowing along the tower wall, that is the side flowing phenomenon, and the treatment capacity of the device is improved.

Description

technical field [0001] The invention relates to a shower. Background technique [0002] As a common chemical equipment, packed tower is usually used in chemical unit operations such as medium absorption, condensation, distillation, evaporation filtration, washing, etc. It is a heat and mass transfer process of gas-liquid contact. During the operation process, the flow direction of gas and liquid is generally countercurrent, the gas rises uniformly from the bottom of the tower, the liquid sprays down from the top of the tower evenly through the spray device, and the gas-liquid two-phase contacts each other through the surface of the packing, thereby heat transfer and quality delivery. In order to achieve the above purpose, the liquid needs to be evenly distributed when it enters the tower. At present, the commonly used liquid spraying device in the tower is: 1. Overflow form: the liquid passes through the annular plenum, and passes through the overflow plate with a V-shaped ...

AI Technical Summary

Problems solved by technology

In order to achieve the above purpose, the liquid needs to be evenly distributed when it enters the tower. At present, the commonly used liquid spraying device in the tower is: 1. Overflow form: the liquid passes through the annular plenum, and passes through the overflow plate with a V-shaped cut. The overflow pipe is evenly distributed into the tower; in this way, the liquid is evenly distributed, but the flow area of ​​the tower is small, the gas flow is not smooth, and the pressure drop is large, which affects the efficiency of the tower

2. Tubular spraying form: The tubular spraying structure is characterized by simple structure, convenient manufacture and installation, and its disadvantage is that the spraying area is small and uneven
