Description
Affiliated technical field
The present invention relates to the atmosphere pollution treatment facility, the innovation of high pressure electrostatic precipitation technology.
Background technology
In the existing high-pressure static cleaner; Dust collecting electrode all is fixed, and its electrostatic induction dust adsorbed has two kinds of ash removal methods: a kind of is that method is removed in the mechanical oscillation of using always; Vibration through vibrator produces falls among the ash bucket dust on the dust collecting electrode; Exist the dust difficult drop-off of strong adhesion, the reentrainment of dust that the dust that comes off forms in moving air has reduced the effect of dedusting.The 2nd, the hydroblasting that is of little use is removed method; On the huge dust collecting electrode of area, spray water, not only consume great amount of water resources, and exist the phenomenon of current vestige skewness; Understand several " the grey islands " that on dust collecting electrode, form, influence the effect of deashing and dedusting.In addition, many, bulky discharge electrodes of quantity and dust collecting electrode are taking a large amount of spaces, soil and steel.Domestic having " moved dust collecting electrode formula high-voltage electrostatic dust separator ", and (patent No.: report ZL955223411), it installs one group of discharge electrode and control of dust collection in a housing, the scheme of a plurality of housings parallel connections or series connection use is also uneconomical.Adopt to move dust collecting electrode outside fixedly scrape its surface dirt of hawk cleaning because the contact face length, air spots is sliding and the effect number of times is few, ash-removal effect can be desirable; To being adsorbed on the inner dust of dust and mobile dust collecting electrode in airflow hole, the slit, outside to scrape hawk inoperative.These dusts not only influence the dust collection function of dust collecting electrode inner surface, and can come off in mobile dust collecting electrode inner loop, form continual airborne dust, thereby influence the dust removing effects of cleaner.
Summary of the invention
The invention reside in the problem that exists to above-mentioned high-pressure static cleaner; Adopt to change curtain formula dust collecting electrode and spray water and add the ash removal method that rotates hairbrush; Design the high-pressure electrostatic wet dedusting equipment that a kind of more compact structure, dedusting are more effective, price is cheaper, to meet the need of market.
The present invention is made up of deduster housing, fixed discharge electrode, commentaries on classics curtain formula dust collecting electrode, deashing device, frame, ash exhauster and supporting power and transmission parts; Its unique distinction is: in same main casing, fixed discharge electrode more than two groups is housed, changes curtain formula dust collecting electrode and its deashing device; Fixed discharge electrode is located at air inlet place and the front of changeing curtain formula dust collecting electrode; The upper end of changeing curtain formula dust collecting electrode is a driven roller, and the lower end is a driven voller, and adapter ring blocks back and air outlet place at fixed discharge electrode around the turnover curtain; In the deashing device, sparge pipe is installed in each group changes the inside of curtain formula dust collecting electrode, the top of driven voller, and rotating brushes is installed in each group changes the outside of curtain formula dust collecting electrode, the below of driven voller, is close to the outer surface that has enough to meet the need curtain.
Because fixed discharge electrode, commentaries on classics curtain formula dust collecting electrode and its supporting deashing device more than two groups are equipped with in the present invention in a housing, have multilayer Electrostatic Absorption and dedusting function, can reduce equipment volume and steel consumption greatly.Sparge pipe in its deashing device is installed in the inside of changeing curtain formula dust collecting electrode, from inside to outside, local water spray deashing, adds rotating brushes, and the more turnover curtain outer surface of band washing brush dust stratification, thereby using water wisely are guaranteed the ash-removal effect of dust collecting electrode.Compare with existing high-pressure static cleaner, have that equipment volume is little, floor space is few, cost is low, reduced investment, advantage that efficient is high, is that a kind of internal structure is advanced, the unique high-pressure static cleaner of ash removal method.
