Description
Technical field
The present invention relates to field of gas purification, particularly relate to a kind of spray system of wet cottrell.
Background technology
Strict further along with the domestic attention to " haze " phenomenon and environmental emission standard, the emission concentration standard of dust (especially fine particle) improves further.Flue gas, after preliminary treatment, need carry out advanced treating further, reduces the dustiness in flue gas and soluble solids dissolved salt, to meet new emission request, realizes qualified discharge.But because the particle of the molecules such as PM2.5 is too small, it is not easily captured in cyclone dust removal, bag-type dust and dry electric precipitation.
Electric cleaner can be divided into tube-type esp and Elex precipitator according to the difference of shape.Electric cleaner can be designed to different electric fields, and flue gas flows through each electric field after entering electric cleaner from import loudspeaker, discharges through outlet loudspeaker.Dust size in flue gas and dust concentration, in the process through each electric field, are the gradient distribution reduced step by step.Traditional electric cleaner is dry electric precipitation device, and the dust be collected on pole plate of dust remover is removed by rapping mode, because wind speed is relatively high, can form the secondary fly-up of dust in rapping process, exacerbate the problem that dust emission exceeds standard.
Wet electrical dust precipitator (patent 201410292593.3) eliminates the rapping apparatus of dust, by nozzle to pole plate and polar curve water spray, uses current scour to complete the deashing of pole plate and polar curve.If the water-flow equation that washes away is uneven, may cause the thorough of pole plate or polar curve deashing, severe patient even can affect safety, the stable operation of electric cleaner.
Therefore, how to arrange that nozzle makes water-flow equation in wet electrical dust precipitator more reasonable, even, deashing is more stable, thorough, has become the technical barrier that those skilled in the art is urgently to be resolved hurrily.
Summary of the invention
For the technical problem existed in above-mentioned prior art, the invention provides a kind of wet cottrell spray system and method, to solve in current technology because the unreasonable deashing caused of water spray not thoroughly and affect the problem of deduster safety, stable operation.
For achieving the above object, the technical solution adopted in the present invention is as follows:

Described positive plate is plank frame, and form is C template, Z-shaped plate.
Described cathode line is linear structure, and form is prickle wire, fish-bone line.
Described suspension and support adopts GH2 duplex pull rod pipe clamp suspension bracket.
Described wet electrical dust precipitator is board-like or horizontal wet electrical dust precipitator.
Use hollow atomizer to rinse dust collecting pole plate in the present invention, by the design to hollow atomizer, make it can spray with discrete fine droplets, thus make to be covered with water smoke in the space of wet electrical dust precipitator.When small dust granules enters wet electrical dust precipitator space, contact with the water smoke in space, the character such as the surface tension of dust granules can be changed, and then promote minute dusts particle generation coalescence, small dust granules diameter is grown up, thus promotes the removal efficiency of dust.
The short circuit that prevents of High-Voltage Electrical Appliances has mainly been come by distance, the hollow atomizer used in the present invention, and drop can be made to form discontinuous distributional pattern aloft, thus can prevent from avoiding high-tension electricity to be short-circuited when touching water.And then, continuous print water spray can be carried out in the electric cleaner course of work, dust collecting pole plate is rinsed, improve the whole efficiency of dedusting.
Compared with prior art, the invention has the advantages that:
Utilize hollow cone nozzle to spray dust collecting pole plate (positive plate), form moisture film on dust collecting pole plate surface, the dust granules becomeing trapped in dust collecting pole plate is flushed in ash bucket.Owing to using hollow cone nozzle, spray institute water requirement can be greatly reduced, reduce the circulating water flow of spray system, reduce the operating cost of system.Simultaneously, owing to using hollow cone nozzle, less on the impact of wet electrical dust precipitator electrion, the continuous operation of spray system can be realized, the operation stopping high-tension electricity not being needed in spray process, ensure that the efficiency of dust collection of wet electrical dust precipitator, decrease the time of flue gas at higher dust emission level run.
Utilize solid cone nozzle to spray discharge electrode (cathode line), by the fast flush of current, the dust granules that cathode line is adsorbed is washed away and enters in ash bucket, reduce or avoid the situation that the discharging efficiency that causes due to dust accumulation reduces.Meanwhile, owing to using solid nozzle to carry out fast flush, the time stopping high-tension electricity running due to cathode line flushing can be shortened, decrease the time of flue gas at higher dust emission level run.
Wet electrical dust precipitator spray system provided by the present invention, structure is simple, and spraying effect is good, and applicability is strong, and making and installation is convenient, and high financial profit, environment protecting is good.
