Novel electrostatic-DEP deduster

Abstract

A provided novel electrostatic-DEP deduster comprises an electricstatic dedusting part and a dielectrophoresis filter part, and an air outlet of the electricstatic dedusting part is connected with an air inlet of the dielectrophoresis filter part; the dielectrophoresis filter part is composed of a DEP purification processing unit; the DEP purification processing unit comprises M DEP purification electrode plates which are in the shape of a hollow cylinder and are in concentric sleeving connection; each DEP purification electrode plate comprises a DEP electrode comprising an anode and a cathode which are oppositely arranged, and the DEP electrode captures particles in air exhausted by the dielectrophoresis filter part through dielectrophoresis force. The novel electrostatic-DEP deduster filters off large-particle dust of inlet air through the electricstatic dedusting part and filters off small particles especially dust capable of entering lung through the dielectrophoresis filter part, so as to realize total-range comprehensive removal of dust particles. The dielectrophoresis filter part employs the dielectrophoresis principle for filtering dust, so that the novel electrostatic-DEP deduster is low in energy consumption, small in pressure loss and low in running cost.

Description

technical field [0001] The invention relates to the technical field of material purification treatment, in particular to a novel 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, the research results of Briti...

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
