Efficient tower opening structure of spray type flue gas desulfurization tower

Abstract

The invention provides an efficient tower opening structure of a spray type flue gas desulfurization tower, belonging to the technical field of flue gas desulfurization. The efficient tower opening structure of the spray type flue gas desulfurization tower comprises a tower body, wherein a first mounting base is fixedly mounted in the tower body; a rotating rod is rotatably connected to the centerof the first mounting base; a sliding groove is formed in the inner side of the tower body; a circular ring is arranged in and slidably connected with the sliding groove; balls are arranged between and connected with the circular ring and the inner wall of the sliding groove in a rolling manner; and a water spraying opening is fixedly formed in the inner side of the circular ring. The efficient tower opening structure of the spray type flue gas desulfurization tower in the invention realizes self-adjustment of the spray amount of an absorbent according to the flowing amount of flue gas, allows the absorbent to be more uniformly distributed in the tower body, improves desulfurization effect, avoids the waste of the absorbent, and enables a mist catching plate to shake, which is beneficialfor rapid falling-off of liquid drops and dust on the surface of the mist catching plate and preventing the blockage of the mist catching plate.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to a tower opening structure of an efficient spray type flue gas desulfurization tower. Background technique [0002] Flue gas desulfurization refers to the process of desulfurizing the flue gas generated after fuel combustion, which is one of the important technical measures to prevent and control air pollution. It is divided into three categories: wet method, semi-dry method and dry method. Among them, wet desulfurization technology is more mature, efficient, and simple to operate, so it is used the most, and spray flue gas desulfurization tower is a typical one in wet desulfurization. kind. [0003] Spray flue gas desulfurization is to use the force of mechanical or air flow to disperse the absorbent into extremely fine mist droplets, and spray them into the desulfurization tower, so that the mist droplets are in contact with the flue gas, and the mist droplets ...

AI Technical Summary

Problems solved by technology

[0003] Spray-type flue gas desulfurization is to use the power of machinery or airflow to disperse the absorbent into very fine mist droplets, and spray them into the desulfurization tower, so that the mist droplets are in contact with the flue gas, and between the gas-liquid two phases A desulfurization method of heat exchange, mass transfer and chemical reaction occurs, but the existing spray-type flue gas desulfurization device is difficult to control the amount of absorbent, resulting in low absorption efficiency, and in order to avoid the absorbent being carried by the flue gas Go, it is necessary to install a fog-catching device at the outlet of the desulfurization tower, but the traditional fog-catching plate is fixed, and when the liquid droplets stay on the fog-catching plate for a long time, it is easy to make dust adhere to the fog-catching plate , resulting in blockage of the mist catcher
