Bipolar prick electric coagulation device

Abstract

The invention discloses a bipolar prick electric coagulation device which is characterized in that the electric coagulation device mainly comprises a housing, a high-voltage electrode, two grounding electrodes and a high-voltage alternating current power supply, wherein the high-voltage electrode comprises a high-voltage polar plate and high-voltage pricks; the grounding electrodes comprise grounding polar plates and grounding pricks; the shapes and the structures of the two grounding electrodes are the same; pinpoints of the grounding pricks of the two grounding electrodes are opposite, and the two grounding electrodes are parallely arranged in two symmetrical edges of the housing; the high-voltage electrode is parallel to the two grounding electrodes, arranged with the two grounding electrodes in an equally spaced manner, and arranged between the two grounding electrodes; the pinpoints of the high-voltage pricks and the grounding pricks are in stagger arrangement relatively; the high-voltage polar plate is connected with the high-voltage alternating current power supply; the two grounding polar plates are both connected with the ground. The electric coagulation device can effectively coagulate fine dust particles in smoke, is convenient for a following electric precipitator to remove dust effectively, and has the characteristics of simple structure, small size, low cost, suitability for industrial popularization and application and the like.

Description

technical field [0001] The invention relates to flue gas dedusting technology, in particular to a bipolar prickly electric coagulator. The electric coagulation combiner can make the dust condense and then be purified and removed by the electrostatic precipitator. Background technique [0002] According to the latest research reports, my country has become one of the areas with the most serious fine particle pollution in the world. The country has begun to pay great attention to and started to deal with PM2.5 pollution. Because these fine dusts can directly enter the human respiratory system, and at the same time, these fine dusts are also the chief culprit of smog weather, which not only affects people's health, but also brings great inconvenience to people's daily life. As the main equipment for industrial dust collection, the electrostatic precipitator will surely become the entry point and key object of fine particle control. However, the traditional electrostatic prec...

[0004] Chinese patents with publication (report) numbers CN1390157A, CN1603004A, CN201168647X, CN201329312Y, CN202590955U, etc. respectively disclose the electrocoagulation method or equipment of the corresponding particles. The pre-charging devices of these smoke dust are usually realized by adding several deformation electric fields. , is essentially an extension of the electric field of electrostatic precipitator. It is to increase the electric field of dust removal in a disguised form to achieve the purpose of improving dust removal efficiency. It does not fundamentally solve the problem of dust charge coagulation and dust removal efficiency.

In addition, charging and coagulation are separated, and after the dust is charged, the use of post-positioned forced cross collisions will result in fewer coagulation times of charged particles, limited actual performance, or lack of charging intensity due to mechanism limitations. Insufficient force, it is difficult to achieve the expected cohesion performance
