The present invention is supplementing vibration dust-cleaning mode, add positive plate and inner body wall on-line rinsing (using the spray electuary invented and provide), more effective removal can stick to the obstinate dust stratification of positive plate and inner body wall, extend the cycle of artificial deashing, thus improve the cleaning efficiency of electric precipitator.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of spray electuary, it is characterized in that, it is made up of following component by weight percentage: lauryl mercaptan ethoxylate 1-5%, 4-dodecylphenol sulfonic acid isopropyl amine salt 1-5%, potassium hydroxide 1-5%, ethylene glycol monobutyl ether 3-8%, five hydrated sodium metasilicate 5-10%, sodium phosphate 1-5%, surplus is water.
As preferably, spray electuary as claimed in claim 1, it is characterized in that, it is made up of following component by weight percentage: lauryl mercaptan ethoxylate 3%, 4-dodecylphenol sulfonic acid isopropyl amine salt 2%, potassium hydroxide 3%, ethylene glycol monobutyl ether 5%, five hydrated sodium metasilicate 7%, sodium phosphate 2%, surplus is water.
Present invention also offers and a kind ofly use the positive plate online ash removal device that above-mentioned spray electuary is electric precipitator, described positive plate is even vertical arrangement in the casing of electric precipitator, it is characterized in that, described online ash removal device comprises: liquid transport pipe is rushed in spray, above its level between positive plate, for providing spray electuary for spray drift; And spray drift, 50cm place above its front 100-200cm being in positive plate is 10 ° of angles with positive plate, and it rushes on liquid transport pipe in every bar spray and is uniformly distributed, its quantity >=1.
As preferably, it is more than 1 group that liquid transport pipe is rushed in described spray.
As preferably, described spray drift rushes the mid-way of liquid transport pipe in every bar spray.
As preferably, described spray drift bore is Φ 9mm.
In addition, present invention also offers the method for the positive plate online ash removal that the above-mentioned spray electuary of use is electric precipitator, it is characterized in that, at interval of 240h, flushing is carried out 1 time to electric precipitator, each sprinkling spray electuary 1h, each weight of spraying spray electuary is 20000kg, and then sprays clear water 10min.
As preferably, in described method, the pressure spraying electuary is used to be 1.1Mpa.
Compared with prior art, the present invention has following beneficial effect:
1, the obstinate dust stratification that the present invention clears up positive plate and inner body wall need not stop production, and spray rinses thoroughly.
2, the dust after using the present invention to carry out spray punching enters below flue-dust retainer and not easily produces reentrainment of dust.
3, the present invention can extend the cycle of artificial deashing, improves production efficiency, positive plate to attach dust stratification fewer, the efficiency of electric precipitator is higher.
