Description

A kind of wet electrical dust precipitator dust collecting pole plate
Technical field
The present invention relates to a kind of wet electrical dust precipitator dust collecting pole plates, belong to environment protection equipment.
Background technology
At present, wet cottrell is generally applicable to electric power enterprise and cement as common fume dust remover Industry.The principle of wet cottrell dedusting is the charging particle made by electrostatic field in flue gas, is driven under the action of electric field Dynamic charged particle moves to dust collecting pole plate, is trapped by pole plate.Moisture film is formed on dust collecting pole plate by flushing water again, by pole plate On particle rinse well, achieve the purpose that remove flue gas in particulate matter.
Dust collecting pole plate is the main member in wet cottrell, coordinates water distribution manner, and it is to receive to form uniform moisture film Dirt pole plate selection necessity one of considers the problems of.And moisture film meets with obstruction in flow process from top to down by gravity on pole plate Shi Rongyi changes flow direction, causes to be also easy to produce " channel " phenomenon in polar board surface, polar board surface is made to be difficult to form the water completely covered Film makes local the problem of easily forming dry spot and serious local inverse corona, reduction efficiency of dust collection.
Chinese patent application No. is 201310528825.6 proposes a kind of wet electrical dust precipitator dust collecting pole plate and its clear Grey moisture film generation type, the mutually isostructural plank of pole plate main body two panels are bonded, the shape after splicing of the groove on two sheet materials Into hydraulic pipeline, water distribution pipeline is located inside pole plate, is arranged in order along flow of flue gas direction, there is a main water supply in pole plate bottom Each water distribution pipeline is connected by pipeline, and is supplied water from bottom to top by internal water distribution pipeline.The pole plate the problem is that: (1) electrode plate structure is complicated, high processing costs;(2) due to using water distribution manner from lower to upper, water pump being needed to provide compared with flood Head, energy consumption are higher;(3) in the water distributing pore on pole plate top by delivery head pressure influence, it is difficult to which water distribution uniformity, surface use non-gold Belong to fabric lining intermittent to rinse, water consumption is big.
Chinese patent application No. is 201420830265.X proposes a kind of shape of wet electrical dust precipitator anode plate moisture film Into device, it includes anode plate and the collecting tank for being arranged on anode plate top, the open top of the collecting tank, and collecting tank Arrangement is there are one the flushing line of setting in parallel on top, is disposed on the side wall of the flushing line and several stretches to liquid collecting Water distributor in slot.Several water distributors are evenly arranged in the lower section of flushing line side wall, and anode plate is made of stainless steel, Collecting tank is made of stainless steel, the cross section semicircular in shape of collecting tank, rectangle or trapezoidal.The shortcoming of the device exists In:Cloth water-bound is more complicated, due to the mode water distribution only with overflow, if pole plate is excessively high easily to form " channel " in polar board surface, Influence being uniformly distributed for moisture film.
Chinese patent application No. is 201210553549.4 proposes a kind of hollow pole plate of porous media material composition Electrostatic precipitator and method, which uses the hollow pole plate that porous media material is formed, and after being passed through water, water passes through porous Jie Material forms moisture film in polar board surface, the particulate matter that polar board surface is deposited on by electrostatic field is trapped, when polar board surface has When the more particulate matter being difficult to clean off deposits, gas is passed through to pole plate inside, gas passes through porous media material in polar board surface Form of short duration air film, eliminating particle object.Water inlet is with supplying alternately.The shortcomings that technical solution, is:By nonmetallic mostly empty The hollow pole plate mechanical strength that material makes is little, and due to will form water outside hydraulic pressure to pole plate by water its own gravity completely Film needs the porous material used to have from the pole plate top feature that aperture gradually reduces from top to bottom, and design requirement is high, difficulty Greatly, while to manufacture cost also high.
Invention content
In view of the above-mentioned problems, the object of the present invention is to provide a kind of wet-esps that can form uniform and stable moisture film Device dust collecting pole plate.
To achieve the above object, the present invention uses following two technical solutions:A kind of wet electrical dust precipitator dust collecting pole plate, It is characterized in that:Including pole plate reinforcing plate, downflow weir formula water distributor and stainless steel cloth;It is set at the top of the pole plate reinforcing plate There is arc groove;The downflow weir formula water distributor is mounted in the arc groove at the top of the pole plate reinforcing plate, the downflow weir The outer diameter of formula water distributor is more than the thickness of the pole plate reinforcing plate;One end of the downflow weir formula water distributor connects with water supply pipe It connects, the other end is sealed end, and multiple effluent troughs are equidistantly opened up along the length direction of the downflow weir formula water distributor;It is described stainless Steel wire wraps up in the surface for spreading on the pole plate reinforcing plate and downflow weir formula water distributor;In the stainless steel cloth, downflow weir formula cloth Two symmetrical triangular prism shaped hollow structures closed at both ends are formed between water pipe and pole plate reinforcing plate.
Further, the pole plate reinforcing plate is one piece of rectangular slab.
Further, the pole plate reinforcing plate and downflow weir formula water distributor use ceramic material.
Further, the pole plate reinforcing plate and downflow weir formula water distributor use corrosion-and high-temp-resistant plastics.
Further, the mesh number of the stainless steel cloth is 200 mesh, is made of 304 stainless steels.
The effluent trough is square groove, vee gutter or arc groove.
The present invention has the following advantages due to taking above technical scheme:1st, the present invention uses downflow weir formula water distributor Water distribution is carried out, it is of less demanding to water supply pressure, it is of less demanding to pipeline pressure resistance degree, it is not easy to plug in operational process, flushing water Can equably it go out from each downflow weir overflow.2nd, the present invention uses ceramics or corrosion-and high-temp-resistant material as downflow weir formula Water distributor and pole plate reinforcing plate can ensure to reduce pole plate total quality while the integral strength of pole plate.3rd, face of the invention For material using 200 mesh stainless steel cloths, light weight, anticorrosion effect are good, wet in interruption spray operation due to using metal material Formula electrostatic precipitator also can normal operation.4th, the present invention is between stainless steel cloth, downflow weir formula water distributor and pole plate reinforcing plate Two symmetrical triangular prism shaped hollow structures closed at both ends are formed, flushing water is made to form moisture film on the outside and in triangular prism Catchmenting by forming moisture film by infiltrating into outside on the inside of stainless steel cloth in shape space, entire water distribution process moisture film is uniform, pole It splashes between plate without foam, effectively avoids the spark discharge caused by water mist.5th, stainless steel wire Netease used by fabric of the invention In replacement, therefore maintenance cost is relatively low.
