Technical field

A kind of electrostatic precipitator for industrial fumes purification involved in the present invention, is specially the dust collecting pole plate in electrostatic precipitator.Background technology

Open type positive plate in electrostatic precipitator is the electrostatic basic theory Coulomb's law of root Ju and invents design, by the energy Coulomb force of electrostatic field known, as long as allow two electrostatic factors in electrostatic field, q ₁with q ₂distance r value is with each other the smaller the better, if can make r → 0, then F value in Coulomb force will reach maximum, and namely electrostatic field function maximizes.Open type blinds positive plate is then reach the critical component making r tend to 0, so name blinds positive plate of the present invention into Coulomb anode plate.

The positive plate that gathers dust in current its electric field of known electrostatic precipitator, be the plate armature of shield type, mostly be the closed fixed polar plate of impermeable vertical hanging tabular, positive plate described in Chinese invention patent " a kind of high efficiency electrostatic dust separator (patent No. ZL200510017874.9) ", for open type, as netted, cellular, grid-like, louvered etc.But its suspended structure is one monolithic construction up and down, particularly open type venetian blind type positive plate, louvre blade is dead by peripheral frame consolidation, add material became uneven, and the reason such as peripheral frame material unit section is large, when deployed permanent or electric field strength rises time, the louvre blade that unit section is little will extend, cause louvre blade severe bends, and make with each other apart from uneven, not only affect airflow uniform distribution, and cause dust stratification to block passage between pole plate, penetrating power is declined, thus increase electric field flow velocity, no matter dust stratification increases or flow velocity increases, all can have a strong impact on electric field dust collection effect and the overall performance of the positive plate that gathers dust.

Summary of the invention

The object of this invention is to provide a kind of Coulomb anode plate, it has the flue dust airflow uniform distribution that can make in electric field, and not easily cause the passage between dust stratification blocking pole plate, penetrating power is comparatively strong, can efficiently catch dirt and be convenient to deashing.

The object of the present invention is achieved like this:. a kind of Coulomb anode plate, it is characterized in that: comprise louvre blade, the overp0unch of louvre blade is also contacted with round steel, upper round steel and upper little band steel are fixed together, upper little band steel upper end is fixed together with upper junction plate again, the both sides, top of upper junction plate and angle steel while fix, the another side of angle steel inserts in the hollow pipe of two ends, two ends hollow pipe is transversely connected and fixed composition framework with U-steel, U-steel has perforation perpendicular on the direction of louvre blade, louvre blade is through the perforation on U-steel, the bottom perforated of louvre blade is also contacted with lower round steel, lower round steel and lower little band steel are fixed together, lower little band steel lower end is fixed together with lower connecting plate again, the two ends of lower round steel and lower connecting plate are all fixed together with hollow pipe.

The present invention has following beneficial effect: the homogeneous texture structurally reaching louvre blade, make flue gas uniformly can enter open type Coulomb anode plate, louvre blade is avoided to become curved dust stratification, and along with the rising of electric field strength and the remote of electrostatic precipitator service time, the anode row entirety that Coulomb anode plate can be made to form can be more and more smooth, working voltage has been impelled more and more to optimize, greatly improve electric field running quality, for many years electrostatic precipitator quality when new clothes is good to solve 100, but can permanent along with service time, will disadvantage worse and worse.This is because the positive plate that gathers dust of prior art is due to when materials hot deformation, because the cross section of frame member and louvre blade is different, coefficient of thermal expansion differs greatly, and material extends naturally to have caused each parts swell increment different and service time of a specified duration, causes louvre blade to bend or each spacing changes, affect airflow uniform distribution, cause the passage between dust stratification blocking pole plate, penetrating power declines, thus increases electric field flow velocity, no matter dust stratification increases or flow velocity increases, all electric field dust collection effect and overall performance can be had a strong impact on.This is the common fault of domestic and international electrostatic precipitator.Therefore Coulomb anode plate of the present invention from the outstanding structure stretched, can have the advantages that generally optimize electric field performance.In addition, Coulomb anode plate of the present invention is highly beneficial to vibration dust-cleaning, because the positive plate that gathers dust of prior art is frame-type solid welding overall structure, single-piece quality is large, rigidity is strong, when making vibration dust-cleaning, amplitude is little, transmit vibration acceleration value little, deashing can be made ineffective, dust collecting pole plate dust stratification, make deleterious, and Coulomb anode plate is when from side arm sinker, because framework is separated with louvre blade, each part quality relatively significantly reduces, rapping power is directly delivered on each louvre blade, also by the independent up direct transmitting vibrations power of framework, until positive plate top, and produce whip and slightly act on, clash into the louvre blade rocking top, so make each parts, high and low all can effectively be delivered to rapping power, ash-removal effect is put in place very much, moreover, rapping carries out shock rapping from the sidepiece of whole row's Coulomb anode plate, tangential direction to the rapping force direction of every block Coulomb anode plate, and be normal direction to each louvre blade of Coulomb anode plate with rapping force direction, the amplitude of obvious louvre blade normal direction and frequency are better than tangentially greatly, therefore Coulomb anode plate can, by effective deashing, will make electric precipitation Be very effective improve, in addition Coulomb anode plate also has manufacture simply, the advantages such as packed and transported is reliable, easy for installation, and does not need high gear milling equipment, is just produced on a large scale with common process, very favourable to propelling environmental protection cause.
