Description

Technical Field

[0001] The present invention relates to the technical field of dust removal, and particularly to a plasma environmental protection treatment device and system for eliminating harmful smoke and dust. Background Art

[0002] The basic principle of plasma dust removal is to utilize an extremely uneven electric field to form a corona discharge and generate plasma. A large number of electrons, positive and negative ions contained therein, under the action of the electric field gradient, undergo inelastic collisions with particulate pollutants in the air, thereby adhering to them and making them charged ions, which are collected by the dust collecting electrode under the action of the applied electric field force.

[0003] It is formed during the production processes of lead concentrate sintering, smelting, and lead alloy preparation, and generally escapes into the air in the form of vapor and then oxidizes into lead oxide dust.

[0049] The working process of the processing system includes the following steps:

[0050] S1: Inhale the dusty air into the processing system;

[0054] S5: Adjust the means of plasma dust removal according to the content of harmful dust and the weight increase rate of the dust;

[0055] S6: Discharge the clean air.

[0056] In the above S3, the measured weight increment of the dust within one minute is , the pressure sensor 25 measures the pressure increment as p, and then the volume increment can be obtained as , since the main components of the dust are lead oxide powder and rock powder, then the relative content n of lead oxide can be obtained according to the relative density of the collected dust.
