A self-regulating flue gas desulfurization device based on airflow swirling

Abstract

The invention provides an self-regulating smoke desulfurization device based on airflow swirling, and relates to the technical field of flue gas desulfurization. The self-regulating flue gas desulfurization device based on air flow rotation includes a tank body, and a partition is fixedly installed inside the tank body. The left and right sides of the partition are fixedly connected with connection ports, and the center of the partition is opened. There is a circular hole, the inside of the circular hole is rotatably connected with a fan blade, and a disc is fixedly installed on the top of the fan blade. The self-regulating flue gas desulfurization device based on the swirling air flow realizes the self-adjustment of controlling the amount of absorbent according to the amount of flue gas, avoids insufficient desulfurization and waste of absorbent, and improves the effect of desulfurization and the efficiency of the desulfurization device. Economical, it can desulfurize the flue gas closer to the middle more effectively, so that the spraying of the absorbent is more targeted, and the droplets generated by the fog-catching plate fall from the center of the fog-catching plate, which facilitates the collection of the absorbent .

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization, in particular to a self-adjusting flue gas desulfurization device based on airflow swirling. 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 are in co...

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. A desulfurization method of heat exchange, mass transfer and chemical reaction occurs, and because the flue gas is not uniform during the discharge process, the traditional spray-type flue gas desulfurization device cannot adjust the absorbent according to the amount and rate of flue gas discharge. Therefore, it is prone to insufficient desulfurization or excessive use of absorbent, and because the unit price of absorbent is high, the by-product equipment is complicated, so the cost of desulfurization is increased, and in order to prevent the flue gas from carrying the absorbent Go, there will be a fog catcher at the outlet of the flue gas, and the droplets collected by the traditional fog catcher will drip down in a scattered manner, which is not convenient for collection
