Description
Technical field
A kind of wet electrical dust precipitator dust collecting pole plate is the utility model is related to, belongs to environment protection equipment.
Background technology
At present, wet cottrell is generally applicable to electric power enterprise and cement as conventional fume dust remover
Industry.The principle of wet cottrell dedusting is to make the charging particle in flue gas by electrostatic field, is driven in the presence 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, reach removing flue gas in particulate matter purpose.
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
One of the problem of dirt pole plate selection necessity considers.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, makes polar board surface be difficult to form the water completely covered
Film, make local the problem of easily forming dry spot and serious local inverse corona, reduce efficiency of dust collection.
The Chinese patent of Application No. 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 sheet material fitting of pole plate main body two panels form, 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 bar water distribution pipeline is connected by pipeline, and is supplied water from bottom to top by internal water distribution pipeline.The problem of pole plate is present be：
(1) electrode plate structure is complicated, high processing costs；(2) due to using from lower to upper water distribution manner, it is necessary to water pump provide compared with flood
Head, energy consumption are higher；(3) pole plate top water distributing pore by delivery head pressure influence, it is difficult to water distribution uniformity, surface use non-gold
Belong to fabric lining intermittent to rinse, water consumption is big.
Application No. 201420830265.X Chinese patent proposes a kind of shape of wet electrical dust precipitator positive plate moisture film
Into device, it includes positive plate and is arranged on the collecting tank on positive plate top, the open top of the collecting tank, and collecting tank
The flushing line of a setting in parallel is disposed with top, is disposed with the side wall of the flushing line and some stretches to liquid collecting
Water distributor in groove.Some water distributors are evenly arranged in the lower section of flushing line side wall, and positive 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 weak point of the device exists
In：Cloth water-bound is more complicated, due to the mode water distribution only with overflow, if pole plate is too high easily to form " channel " in polar board surface,
Influence being uniformly distributed for moisture film.
The Chinese patent of Application No. 201210553549.4 proposes the hollow pole plate that a kind of porous media material is formed
Electrostatic precipitator and method, the device use 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 is through porous media material in polar board surface
Form of short duration air film, eliminating particle thing.Water inlet is with supplying alternately.The shortcomings that technical scheme, is：By nonmetallic more empty
The hollow pole plate mechanical strength that material makes is little, and due to completely water will be formed outside hydraulic pressure to pole plate by water self gravitation
Film is, it is necessary to which the porous material used possesses from the pole plate top feature that aperture progressively reduces from top to bottom, and design requirement is high, difficulty
Greatly, while manufacturing cost is also high.

Portion is provided with arc groove；The downflow weir formula water distributor is arranged in the arc groove at the top of the pole plate reinforcing plate, described
The external diameter of downflow weir formula water distributor is more than the thickness of the pole plate reinforcing plate；One end of the downflow weir formula water distributor and feed pipe
Road connects, and 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 cloth 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
Two symmetrical triangular prism shaped hollow structures closed at both ends are formed between formula water distributor and pole plate reinforcing plate.
Further, the pole plate reinforcing plate is one piece of rectangular slab.
Further, pole plate reinforcing plate and downflow weir the formula water distributor uses ceramic material.
Further, pole plate reinforcing plate and downflow weir the formula water distributor uses corrosion-and high-temp-resistant plastics.
Further, the mesh number of the stainless steel cloth is 200 mesh, is made up of 304 stainless steels.
The effluent trough is square groove, vee gutter or deep-slotted chip breaker.
For the utility model due to taking above technical scheme, it has advantages below：1st, the utility model uses downflow weir
