Description
Technical field
The utility model relates to a kind of position limiting structure of electric dust-collector anode system.
Background technology
The temperature of new type dry kiln kiln hood flue gas electric cleaner reaches as high as 400 DEG C, and kiln exit gas is as processed or conditioning Tower fault without conditioning Tower, and electric cleaner temperature also can reach 350 DEG C, and so high transient temperature is a kind of test to the thermal expansion of pole plate.Along with the progressively expansion of cement plant scale, the processing air quantity of electric cleaner improves constantly, and causes equipment scale increasing, swell increment and internal difference in temperature are also increasing, its result causes change of distance between the heavy dirt utmost point and discharge electrode, and supply voltage declines, and efficiency of dust collection reduces.How reducing to greatest extent die opening variable quantity, when hot operation, the two poles of the earth interval error remains in cool tone acceptance criteria error, is the key point of electric cleaner.
Anode claims again the heavy dirt utmost point or dust collector pole, is the core component of electric cleaner, works the effect of gathering dust.Positive plate forms with the rolling of mild steel Q235A cold coil conventionally, and the combination of positive plate is referred to as anode row, all leaves 15-20mm gap between pole plate.Heavy dirt pole plate lower end is connected after clamping with concavo-convex cover and bolt and nut with rapping trip rod.Anode row after installation, each row's centreline spacing deviation is not more than 5mm, and heteropole spacing deviation is not more than 10mm.Because electric cleaner is higher to the installation requirement of pole plate, polar curve, thus the thermal expansion amount of electric field inside to control within the specific limits, the stable operation of guarantee equipment, guarantee emission compliance.Temperature normally remains on 250 DEG C of left and right in its electric field of the electric cleaner of kiln hood, often operate in 300 DEG C upper and lower, be instantaneously greater than 400 DEG C even higher.So high temperature causes pole plate thermal deformation serious, if do not taked adequate measures, and long-play under this operating mode, pole plate is easy to distort, beats arch, die opening does not reach designing requirement, very easily causes the phenomenons such as electric field short circuit, electric discharge.
In order to prevent the thermal deformation of pole plate, must install stopping means additional at anode row two ends, only allow the flexible of its above-below direction, left and right and rapping direction ensure its size by stopping means.Prior art is to install a pole plate lower plate additional at anode row two ends, and this connecting plate is opened U-shaped draw-in groove at the correspondence position of each trip rod, and connecting plate is stuck on anode row vibrating rod from top to bottom.Because this stopping means is not obvious at the position-limiting action of airflow direction, when transient temperature too high, when vibration dust-cleaning, anode lower plate is easy to bending, cause the phenomenons such as vibrating rod misplaces with it, comes off, directly cause anode row bulk deformation, same to pole span, heteropole carpenters square are cun up to standard, even electric field short circuit, does not reach dust collection effect.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, and a kind of anode of electric dust separator position limiting structure is provided, to ensure reliable in structure, to avoid the system failure.
The utility model is that technical solution problem adopts following technical scheme:
