Abstract
The utility model discloses a highly efficient cyclone electrofilter, mainly used for fume control of dead burnt magnesite vertical kiln. An air inlet and an air outlet are arranged on both sides of the upper part of the shell of the device, while a cyclone cylinder is arranged on the lower part of the shell. Groups of barbed corona wires around which are provided with core wall are arranged in the cyclone cylinder. Reflecting screen is below the core wall. The corona wire, the core wall and the external cylinder form a dedusting section; a refluxing pipe fitting connected with a refluxing pipe whose upper part is connected with an air inlet is arranged on the lower part of the cylinder head; an insulating sub-chamber in which corona electrode is provided is arranged on the upper part of the device. The corona electrode is connected with the bus of the EHV power supply equipment. A vibration device is arranged on the upper part of the sub-chamber room with vibration insulator devices. The utility model has the advantages of integration of cyclone dedusting and electric dedusting, high efficiency of purifying coarse dust particles and application on fine dust particles.
Description
Technical field
The utility model relates to a kind of electric cleaner, is mainly used in common dead burnt magnesite sand shaft furnace smoke and dust treatment.
Background technology
The dead burnt magnesite shaft furnace will produce volume of smoke in calcination process, its concentration is bigger, is generally 7-10g/Nm
3But the shared large percentage of coarsegrain reaches more than 2/3 in the dust.The flue-gas temperature of dead burnt magnesite shaft furnace is very high, under normal circumstances be 100-400 ℃, its variations in temperature is cyclic fluctuation with material loading, calcining, discharging, when artificial material loading is operated untimely or is calcined undesired artillery fire, its EGT can reach 800-1000 ℃, and is the highest even can reach more than 1400 ℃.Brought certain difficulty so just for this kiln waste gas dedusting.
The smoke and dust treatment of China's present dead burnt magnesite sand kiln does not have desirable precedent to follow as yet, the conventional cleaner that uses mainly contains wet scrubber, cyclone dust collectors, ceramic multicyclone dust collector, still all exists some defectives owing to above-mentioned deduster, all is not widely used.
The shortcoming of wet scrubber is to consume a large amount of water, the mud conditioning difficulty, and need consider antifreeze problem winter, equipment corrosion is serious; The purification efficiency of cyclone dust collectors is low, does not reach discharge standard far away; The efficient of ceramic multicyclone dust collector is a little more than cyclone dust collectors, but can't satisfy qualified discharge, and in addition, the sub-diameter of the whirlwind of ceramic multicyclone dust collector is very little, and dead burnt magnesite kiln dust bonding is very strong, very easily stops up, and therefore can't steady in a long-term move.
Summary of the invention
The purpose of this utility model provides a kind of new and effective whirlwind electric cleaner that adopts extra-high pressure to overcome the prior art shortcoming, to solve the governing problem of dead burnt magnesite sand shaft furnace flue dust.
New and effective whirlwind electric cleaner, it is characterized in that: the both sides, housing top of this device are provided with tangential air inlet and air outlet, lower housing portion is the whirlwind tube, be provided with many group acupuncture corona wires in the whirlwind tube, be provided with the core tube around many group acupuncture corona wires, core tube bottom is a radiation shield, and corona wire and core tube and outside cylindrical shell constitute the dedusting section; Be provided with the backflow tube head in device cylindrical shell bottom, the backflow tube head connects return line, and return line top connects air inlet; Device top is provided with insulator chamber, is provided with corona discharge electrode in the insulator chamber, and corona discharge electrode is connected with the bus of super-pressure power supply unit, is provided with vibrating device on insulator chamber top.
The advantage of new and effective whirlwind electric cleaner is: collection cyclone dust removal and electric precipitation one, and to dust coarse granule purification efficiency height, simultaneously, also very suitable to the dust fine particle.
Description of drawings
Fig. 1 is the structural representation of new and effective whirlwind electric cleaner.
Fig. 2 is the structure side view of new and effective whirlwind electric cleaner.
The specific embodiment
See Fig. 1, new and effective whirlwind electric cleaner, the both sides, housing 5 top of this device are provided with tangential air inlet 14 and air outlet 4, lower housing portion is a whirlwind tube 16, be provided with many group acupuncture corona wires 8 in the whirlwind tube, be provided with core tube 9 around many group acupuncture corona wires, core tube bottom is a radiation shield 10, and corona wire and core tube and outside cylindrical shell constitute the dedusting section; Be provided with backflow tube head 11 in device cylindrical shell bottom, backflow tube head 11 connects return line 15, and return line 15 tops connect air inlet 14; Device top is provided with insulator chamber 2, is provided with corona discharge electrode 3 in the insulator chamber, and corona discharge electrode 3 is connected (Fig. 2) with the bus 17 of super-pressure power supply unit, is provided with vibrating device 1 on insulator chamber top; The device bottom is provided with ash bucket 12, and the ash bucket bottom is provided with unloading valve 13; Be provided with manhole door 6 and hand hole door 7 on the top of housing.
The course of work of this device is: apply negative high-voltage on corona discharge electrode, make itself and Whirlwind barrel form high voltage electric field, after dusty gas enters the deduster cylindrical shell by the air inlet spiral, when gas obtains high speed rotary motion, under in centrifugal force and electrostatic force, acting on, dust produces strong centrifugation with air-flow in cylindrical shell, thicker dust granule falls into ash bucket.Thinner dust granule is got back in the cylindrical shell by air inlet by the return air pipeline, drops on the collecting plate, and the effect by the top rapping apparatus falls into ash bucket.
