An electrostatic-dep dust collector

Abstract

The present invention proposes a novel electrostatic-DEP dust collector, comprising an electrostatic dust removal unit and a dielectrophoresis filter unit, the air outlet of the electrostatic dust removal unit is connected to the air inlet of the dielectrophoresis filter unit, and the dielectrophoresis filter unit is purified by DEP The DEP purification treatment unit consists of M DEP purification electrode plates, the M DEP purification electrode plates are hollow cylindrical and concentrically set together, the DEP purification electrode plates include DEP electrodes, and the DEP electrodes include oppositely arranged anodes and cathodes. The DEP electrode traps particulate matter in the exhaust gas of the electrostatic precipitator through dielectrophoretic force. The present invention filters out the large particle dust in the air intake through the electrostatic dust removal part, and filters the small particle, especially the dust that can enter the lungs, through the dielectrophoresis filter part, so as to realize the comprehensive removal of the dust particles in the whole range. The dielectrophoresis filter unit of the present invention uses the principle of dielectrophoresis to filter dust, and has low energy consumption, small pressure loss and low operating cost.

Description

technical field [0001] The invention relates to the technical field of material purification treatment, in particular to an electrostatic-DEP dust collector. Background technique [0002] PM2.5 is particles smaller than 2.5 microns, also known as particles that can enter the lungs, which can enter the alveoli and even the blood system of the human body, directly causing cardiovascular diseases and other diseases. PM2.5 has a large specific surface area and is usually enriched with various heavy metal elements, such as As, Se, Pb, Cr, etc., as well as organic pollutants such as PAHs, PCDD / Fs, VOCs, etc. These are mostly carcinogens and genotoxic mutagenesis Material hazards are extremely high. Known health effects of PM2.5 include increased mortality in patients with severe and chronic diseases. It can worsen diseases of respiratory system and heart system, change lung function and structure, and change immune structure. In December 2000, British experts also showed that S...

Problems solved by technology

[0003] At present, the electrostatic precipitator widely used in industry has been widely used because of its large amount of flue gas treatment and small pressure loss of the precipitator body. However, the use of the electrostatic precipitator also has its limitations. It is easily affected by many factors such as the physical and chemical properties of flue gas and dust (such as flue gas temperature, flue gas humidity, flue gas velocity, dust particle size distribution, dust viscosity, sulfur content, etc.), especially when dealing with high specific resistance dust And fine dust (especially dust below 10um, the electrostatic precipitator has limited ability to collect fine dust, because fine dust is difficult to charge, and the electrode vibrates to generate secondary dust, so that the captured particles escape with the airflow), Electrostatic precipitator shows its incompatibility

[0004] The electrostatic precipitator is not effective in removing particles below 10um, especially the particles that can enter the lungs (with a particle diameter of 2.5um or less). In the atmosphere, it has buried hidden dangers for the health and safety of the public
