Detailed description of the invention
See figures.1.and.2 and the utility model is described further.
The utility model Coulomb electric precipitator comprises housing 1 and positive plate 2 and cathode line 7.It is inner that positive plate 2 and cathode line 7 are installed in housing 1.Housing 1 top above positive plate 2 and cathode line 7 is provided with several spray head 5, is arranged on the outside of housing 1 with the water pipe of the spray head 5 be connected.Spray head 5 antianode plate 2 and cathode line 7 spray.Bottom housing 1, be also provided with ash bucket 6, in order to collect spray waste liquid, discharge from the osculum bottom ash bucket 6.
Antianode plate 2 and cathode line 7 implement spray following benefit: the dust granules 1, in waste gas is easily conducted electricity by after spray liquid absorption; 2, take away a large amount of used heat after spray liquid and waste gas carry out heat exchange, exhaust gas volumn reduction, gas flow rate decline, and dust granules and oil droplet are easily captured; 3, spray liquid can rinse positive plate 2 and cathode line 7, can not dust stratification in positive plate 2 and cathode line 7, does not need disassembly, cleaning or vibration dust-cleaning; 4, positive plate 2 forms spray liquid liquid film, electric conductivity strengthens; 5, the gas pollutant in waste gas, as SO

3deng, spray liquid can be dissolved in, thus gas pollutant is removed from waste gas, reach the object of desulphurization denitration.
The spray liquid of the utility model Coulomb electric precipitator embodiment can be different according to the composition different choice of process gas liquid, this example selects two kinds of spray liquids, and one is running water, and one is limewash.Select running water as spray liquid in the ordinary course of things.Running water cost is low, is easy to get, and has certain electric conductivity, is suitable as the spray liquid of utility model Coulomb electric precipitator.When needing gas pollutant content in waste gas to be processed large and when being mainly acidity, selecting limewash to act as spray liquid.Lime aboundresources, limewash is with low cost, such as, to pickling gas pollutant, SO

yetc. there being good assimilation effect, be suitable as desulfur denitrate dust collecting spray liquid.
Described housing 1 both sides are respectively equipped with air inlet pipe 3 and escape pipe 4.Air inlet pipe 3 and escape pipe 4 are designed to V-shape near housing 1, be exactly specifically that air enters rear actual internal area from air inlet pipe 3 and increases gradually, and actual internal area diminishes gradually when escape pipe 4 flows out, waste gas is made to be much slower than gas flow rate in pipeline at the gas flow rate of housing 1 inside like this.The reduction of air velocity is conducive to positive plate 2 and catches solid particle and oil droplet in waste gas, and being also conducive to increases the spray time of waste gas in housing 1, thus increases the effect of spray.
The spray head 5 that the utility model Coulomb electric precipitator spray head 5 should select a kind of atomizing effect best, forms water smoke by spray liquid atomization, falls and drench between positive plate 2 and cathode line 7.Atomizing effect is better, and drop is also better to the adsorption effect of dust.
When waste gas enters housing 1 by air inlet pipe 3, first due to the change of sectional area of ventilating, reduce the flow velocity of gas, then positive plate 2 is passed into, cathode line 72 carries out electric precipitation, its principle be by grit in flue gas when an admission passage just by charged polarization, when synchronously entering the space of open type Mobile pole plate with air-flow, namely be moved pole plate to catch, if also have minute quantity grit for dust collector pole of blowing out, but because having corona wire too in side passage, also can be compressed on dust collector pole by the effect of Coulomb force in second channel, play the effect of gathering dust for twice, grit is made to be difficult to escape.While positive plate 2, cathode line 7 carry out electric precipitation, Water spray is carried out to it.Spray can adsorbent solid grit, increases the electric conductivity of solid grit and positive plate 2 cathode line 7, rinses positive plate 2 and cathode line 7 simultaneously, prevents dust stratification, can also absorb the gas pollutant in waste gas, realize desulphurization denitration.Spent shower water is collected by ash bucket 6, discharges from osculum.Waste gas after above-mentioned electric precipitation Water spray integrated treatment flows out from gas outlet.By above-mentioned flow process, absorb the used heat of waste gas, complete the desulphurization denitration process to waste gas and dust removal process, the pollutant load in waste gas can control at below 10mg/m3.And the utility model Coulomb electric precipitator in use just carries out water flushing at antianode plate 2 and cathode line 7, do not need dismounting, rapping dedusting, save human cost and equipment maintenance cost.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
