Description
[technical field]
The utility model relates to flue gas purifying equipment technical field, and particularly the technical field of electric dust collector is closed in dry wet mixing.
[background technology]
The operation principle of electric cleaner is substantially identical, high voltage electric field is produced by the anode and cathode of equipment, when the gas containing dust granules is by high voltage electric field, gas is ionized, collide with dust in the process of electronegative gas ion anode motion, make dust grain lotus electronegative, anode motion under the effect of electric field force, dust grain is deposited on positive plate.Electric cleaner is of a great variety, liquid dust removing and deashing whether is adopted according in dust removal process, electric cleaner is divided into dry electric precipitation device and wet electrical dust precipitator, dry dust removal generally drives brush motion to carrying out the removing of collecting electrode plate by beaing collecting electrode plate or mounting rotor of electric motor, the complex structure of motor dust out simultaneously, maintenance inconvenience, dust removing effects is not very desirable; Wet dust removal generally by circulating water to the top-down flushing of collecting electrode plate.
Dry electric precipitation device is most widely used, topmost dedusting means at present, there is the advantages such as smoke treatment amount is large, technical process is simple, operation and maintenance cost is low, but dry electric precipitation device remains corona wire electric discharge, dust collecting electrode collects dust, and inverse corona and dust fly upward the solution that problem does not obtain all the time again.There is following point: 1, not easily collecting high resistivity dust.Because high resistivity dust resistance value is high, not easily neutralizes in time, occur remaining anion and gather, anode surface electric-field intensity is weakened when charged grit arrives collecting polar plate, grit migration velocity declines.When dust constantly gathers, field intensity of gathering dust is equal with inverse corona field intensity, or is greater than when gathering dust field intensity, and cause partial breakdown, dust collector efficiency declines to a great extent.2, not easily low resistivity dust is purified.Low resistivity grit due to bear electricity neutralizes when arriving collecting polar plate immediately, also has little time sticky integrated agglomerate and has just departed from pole plate, again float to flue, need again charged.
Wet electrical dust precipitator has the following advantages compared with dry electric precipitation device: do not need rapping equipment, avoid reentrainment of dust; Due to pole plate having water membrane all the time, flue dust become trapped in after on pole plate and is rinsed by moisture film immediately, the phenomenon of the particle that can not be captured again in Returning flow.But still there are some problems in wet electrical dust precipitator: flushing process flowing water flowing water on collecting electrode plate is uneven, can not well dedusting; Conventional flow-type bath causes the waste of water resource, and the cost of wastewater treatment is simultaneously also very high; In addition, wet scrubber is not suitable for the dedusting of the high-temperature flue gas such as fire coal boiler fume.
According to statistics, ash-transmission system blocks up ash forces electric cleaner to be stopped transport, and accounts for 30% ~ 40% of the total accident rate of electric cleaner.In the actual motion of electric cleaner, usually occur blocking up grey or that paulin is grey phenomenon in ash bucket, cause the defeated ash of electric cleaner smooth, reduce the efficiency of dust collection of electric cleaner.When ash stifled in ash bucket or paulin grey and when arriving the pole plate of electric cleaner, easily cause electric field short circuit, affect the safe operation of electrical equipment, damage the internals of electric cleaner simultaneously, cause the distortion etc. of electric cleaner pole plate, polar curve, produce the damage of unrepairable, and electric field may be caused to trip.
