Desulfurization tower for efficiently treating flue gas

Abstract

The invention discloses a desulfurization tower for efficiently treating flue gas. The tower comprises a support and a tower body fixed at the upper end of the support; the left end, the top end and the right end of the tower body are provided with a flue gas inlet, a flue gas outlet and an absorption mist inlet respectively; a stepping motor is arranged inside the left end of the tower body, a desulfurization cavity is formed in the tower body, and a spraying mechanism connected with an output shaft of the stepping motor is arranged in the desulfurization cavity; the spraying mechanism is matched with the absorption mist inlet, the output shaft of the stepping motor is in key connection with a second driving gear, and the upper end of the second driving gear is meshed with a second drivengear. The desulfurization tower has the advantages that a mist tube can revolve and rotate around a rotating shaft, so that the expanding range of sprayed absorption mist is expanded, the absorptionmist is distributed uniform and fully reacts with the flue gas, and bristles on a brush roller are used for carrying out synchronous cleaning on spraying holes.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a desulfurization tower for efficiently treating flue gas. Background technique [0002] With the continuous development of social industry, the degree of industrialization is getting higher and higher, and the scale of production is expanding, and more and more flue gas is discharged into the atmosphere. Among the various gaseous pollutants that affect air quality, the amount of SO2 flue gas The largest and most influential, it causes acid rain, destroys the ecological environment, and affects people's health. Therefore, before these industrial flue gases are discharged into the atmosphere, they all need to be desulfurized through a desulfurization tower. [0003] However, the spraying device in the desulfurization tower needs a high-pressure pump to spray out the desulfurization absorption mist. The nozzle of the spraying device is relatively easy to block, and because ...

AI Technical Summary

Problems solved by technology

[0003] The spraying device in the desulfurization tower needs a high-pressure pump to spray out the desulfurization absorption mist. The nozzle of the spraying device is relatively easy to block, and because the sprayed absorption mist is directed and does not have many opportunities to contact with the flue gas, so flue gas desulfurization The efficiency is not high, and the desulfurization effect is not good;
