Description
Technical field
The utility model relates to electrostatic dust collection equipment, is specifically related to a kind of positive plate of wet cottrell.
Background technology
Along with people improve constantly the combined pollutant harm environment such as fine dust, acid mist, heavy metal and healthy understanding, impel improving constantly of atmosphere pollutants emission standards, new discharge standard requires that the emission level of the pollutants such as fine particle, acid mist, heavy metal is lower, traditional flue gas absorbing device has good control effects to part pollutant in flue gas, but fine dust, heavy metal, SO
3the combined pollutants such as acid mist are still to be paid close attention to and is needed the eager difficult problem solved.Flue gas through absorption tower washing after, unabsorbed fine dust, SO
3the combined pollutants such as acid mist not only produce secondary pollution, the more important thing is and can produce serious harm to the health of people.The downstream of chimney wind direction, often can see so-called " gypsum rain ", or has " blue smoke " of long cigarette tail.
As the terminal fine processing equipment of air combined pollutant, wet cottrell can be used for the discharge controlling the materials such as acid mist, fine dust, mercury, metal.Wet cottrell comprises cathode line, positive plate, insulated case, spray equipment and power supply.The main operational principle of wet cottrell is substantially identical with dry collector, namely the gas containing dust granules in flue gas, when being connected to the high voltage electric field formed between the cathode line (also known as corona discharge electrode) of high-voltage DC power supply and the positive plate of ground connection and passing through, due to negative electrode generation corona discharge, gas is ionized, now, electronegative gas ion, under the effect of electric field force, pole plate motion on the sunny side, collide with dust granules at the volley, then make grit lotus with negative electricity, grit after charged is under the effect of electric field force, also anode motion, after arriving anode, release with electronics, grit is then deposited on positive plate, with water, dust is rinsed out again, by rapping the ash on positive plate to be shaken with dry electric precipitation device and drop down onto ash bucket and unlike, wet cottrell, water to be sprayed onto and positive plate to make dust be washed in ash bucket discharge with water.Therefore, can form at positive plate the core technology that complete uniform moisture film is wet cottrell.
At present, conventional wet electrostatic precipitator positive plate, its structural representation as shown in Figure 1, this wet cottrell is two subject matters, one is under the purging effect of flue gas, and what be subject to is the effect of shearing force, and moisture film easily deforms, formed " water wave ", affect the efficiency of dust collection of wet cottrell; Two is that the restriction that the height of the positive plate of this wet cottrell is subject to structure cannot be increased, and has certain restriction to the dust-collecting area of wet electrical dust precipitator.
Utility model content
The utility model technical issues that need to address are to provide and a kind ofly do not limit dust-collecting area and can form the wet cottrell of complete uniform moisture film at positive plate.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A positive plate for wet cottrell, positive plate is corrugated plating, and positive plate total length is 818mm, and thickness is not less than 1mm, is highly 8 ~ 12m; The cross section of described corrugated plating comprises five ripple groups, and each ripple group is formed by connecting by the identical convex surface of straight length and a concave surface; The subsequent corrosion of described concave surface and convex surface is 150mm, and the straight length of each ripple group is 163.6mm.
Further improvement of the utility model is: the height of positive plate is 10m.
Further improvement of the utility model is: positive plate is one time punching molded corrugated plating.
Further improvement of the utility model is: positive plate is stainless steel.
Owing to have employed technique scheme, the technological progress that the utility model obtains is as follows:
The positive plate section that the utility model adopts is corrugated structure; there is good bending resistance; when flue gas skims over from positive plate outer surface; moisture film due to positive plate concave surface is subject to the protection of convex surface positive plate; the shearing force that the power that moisture film is subject to will be divided into the extruding force of vertical anode plate with parallel positive plate; shearing force is cut down greatly, ensure that the uniform and stable property of anode surface plate moisture film.
Anode plate structure length of the present utility model can reach 8 ~ 12m, and its surface is curved-surface structure, adds the contact area of dust and positive plate, strengthens dust removing effects; Under condition of the same area, compared with slab construction positive plate, wall thickness can also be reduced; Identical at wall thickness, width, under the condition that rigidity is substantially identical, positive plate of the present utility model can also save the steel of at least 8%.This patent positive plate adopts one time punching molded process technology, convenient and simple, can realize forming stable moisture film, improves efficiency of dust collection.

Detailed description of the invention
Do further to describe in detail to the utility model below in conjunction with accompanying drawing:
A positive plate for wet cottrell, positive plate is corrugated plating, and this corrugated plating is by one time punching molded, and the cross section of this corrugated plating comprises five ripple groups, and as shown in Figure 2,3, each ripple group comprises an identical convex surface of straight length and a concave surface; The subsequent corrosion of concave surface and convex surface is 150mm.The straight length of each ripple group is 163.6mm, and the total length of positive plate is 818mm.Positive plate thickness is not less than 1mm, and height can reach 8 ~ 12m, is preferably 10m.Anode sheet material selects corrosion resistant stainless steel material to be made.
