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, carrying out advanced treating further, reduces the dustiness in flue gas and soluble solids dissolved salt, to meet new emission request, it is achieved qualified discharge. But owing to the granule 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 may 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 are in the process of each electric field, in the Gradient distribution state reduced step by step. Traditional electric cleaner is dry electric precipitation device, and the dust collected on pole plate of dust remover is removed by rapping mode, owing to wind speed is of a 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, is sprayed water to pole plate and polar curve by nozzle, uses current scour to complete the deashing of pole plate and polar curve. If the water-flow equation that washes away is uneven, it is possible to causing the thorough of pole plate or polar curve deashing, severe patient even can affect the safe and stable operation of electric cleaner.
Therefore, how arranging that nozzle makes water-flow equation in wet electrical dust precipitator more reasonable, uniform, deashing is more stable, thorough, it has also become the technical barrier that those skilled in the art is urgently to be resolved hurrily.
