Problems solved by technology

[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

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...
