A method and system for agglomerating charged dust

Abstract

The application provides a coagulation method of charged dusts, which is applied to the coagulation process of heteropolar charged dusts in an alternating electric field. The coagulation method comprises the following steps of: carrying out shooting on charged particles in a coagulation electric field, wherein the charged particles comprise charged dusts and coagulated bodies obtained by coagulation of the charged dusts; analyzing an image, obtaining the distribution rule of the volume of the charged particles and distinguishing coagulation stages in the electric field according to the classification rule; analyzing the states of the charged particles according to the preset analysis rule corresponding to all the coagulation stages, wherein the state of the charged particles comprises the motion state and / or the form state of the charged particles; and when the states of the charged particles do not meet the preset rule, adjusting the electric field, enabling the stressing of the charged particles to be changed and further enabling the states of the charged particles to be changed. The coagulation method provided by the invention has the advantages that the coagulation process of the charged dusts in the coagulation electric field is controlled, so that the charged and coagulated bodies can reach an airflow distribution system of a flow guide plate of a dust remover quickly and accurately and the dust removing efficiency is improved.

Description

technical field [0001] The application belongs to the field of environmental protection and dust removal, and in particular relates to a method and system for condensing charged dust. Background technique [0002] In the process of industrial production, a large amount of dust that can be inhaled by the human body (dust particle size less than 10 microns) is produced that is extremely harmful to human health and poses a threat to human life and health. [0003] PM (Particulate Matter, solid or liquid particulate matter in the atmosphere) 2.5 in inhalable dust is a particulate matter that can enter the lungs. Its particle size is small, but it is rich in a large amount of toxic and harmful substances and stays in the atmosphere for a long time. The distance is far, so it is more harmful to human health. Therefore, the world is stepping up its efforts to meet the emission standards of PM2.5, which can enter the lungs. [0004] At present, the collection of PM2.5 generally ad...

Problems solved by technology

[0006] However, with this method, charge loss will be caused when the charged dust collides with the spoiler column, making it difficult to control the particle strings formed during the coalescence process, which will affect the subsequent condensation growth, and the spoiler column will cause The turbulence of the rear air flow, when the condensate moves to the air distribution system of the deflector of the dust collector, it will be affected by the air flow, so that the condensate directly reaches the inner wall of the condensate device or the flue during the movement, and cannot reach the dust collector. The air distribution system of the deflector deflector has an impact on the dust removal efficiency
