Description
Technical field
The present invention relates to a kind of electric dust collection device that has tornadotron, specifically a kind of vertical electrostatic precipitator that integrates gravity, cyclone dust collection.
Background technology
Cyclone dust removal is the centrifugal force that utilizes the dusty gas of rotation to produce, the gas-solid separator of a kind of dry type that dust is separated from air-flow.The above dust efficient of 5 ~ 10um is higher for capturing, separating, and is characterized in simple in structure, and Operation and Maintenance is simple, and operating characteristics is stable, not limited by the concentration-temperature of dusty gas.
Thereby cottrell is the device that utilizes the fine grit of electrostatic attraction that gas purification is reached to gather dust purpose.Grit below the particle diameter 5um is had good removing effect, if service condition is suitable, its efficiency of dust collection can reach 99% even higher.Its advantage is: the dust-collecting efficiency height, and the smoke treatment amount is big, and consumed power is few, is adapted to the recovery of high-temperature flue gas, and the automaticity height.
At present for the research of dust collector pole, corona discharge electrode and the rapping aspect of cottrell comparative maturity.Domestic research for the combined cottrell of principle at present is fewer.(patent No.: CN201030328) this utility model discloses a kind of combined type cottrell to the combined type cottrell, comprise housing, blast pipe, air outlet, central air hose, vibrator, corona electrode, ash bucket, ash-valve, equal flow cone, ash bucket is arranged on lower part of frame, the below of ash bucket is provided with ash-valve, central air hose is arranged on the interior central authorities of housing, be provided with corona electrode between the lateral surface of central air hose and the medial surface of housing, the top of housing is provided with blast pipe and links with central air hose, the top of housing also is provided with air outlet, the lateral surface of housing is provided with vibrator, the below of central air hose is provided with equal flow cone, also comprise and be provided with the break-in flow plug in the central air hose successively, following break-in flow plug, all the below of flow cone is provided with dust-laying taper, is provided with the bottom air distribution plate between the inner bottom part of housing and the central air hose outer bottom.This utility model can make crude particle dust realize pre-separation effectively, and the concentration of the dusty gas that enters the dedusting electric field region is reduced greatly.Because realize in the cyclone dust collection centre airduct that whirlwind tube axial dimension is consistent with the electric field short transverse, so whirlwind tube axial dimension is big, can only be centre because of the whirlwind tube in addition, when the processing air quantity is big, the whirlwind cylinder size is increased, thereby the cyclone dust collection weak effect.(patent No.: CN1266744) cyclone-type electric dust collector is that a kind of centrifugal inertia, electric-field charge and electric field of integrating filters the cleaner that gathers dust to cyclone-type electric dust collector.Its principal character is: by the rotation of driven by motor rotor, guiding and forcing enters electricity and receives dusty gas rotation and motion in the electrical equipment, rotor is provided with fan blade and electrode, high speed rotation at rotor forms intensive electric field net simultaneously, the rotor outside is provided with different electrodes according to different principles and forms different electric fields and interaction, along with rotation and the motion of gas, dust is being collected under centrifugal force and the electric field force effect and in intensive electric field net.This cottrell is by the rotation of rotor steering current, structure relative complex.
(patent No.: be a kind of combination vertical barrel electric cleaner CN2329446), belong to the dedusting technology field, it is combined by cyclone dust collector and electric dust collector combination vertical barrel electric cleaner.Cyclone dust collector is made of a plurality of whirlwind, and each whirlwind is coaxial with superposed electric field.Electric dust collector is vertical barrel, and its dust collector pole is formed by a plurality of square terrace with edge shape umbrella sheets series connection, and dust falls into big ash bucket from umbrella sheet outer rim, and the big ash bucket branch that the whirlwind seed cell is provided with little ash bucket and the electric cleaner ash of starting discharging has been avoided reentrainment of dust.This dust arrester is compared with the combined electrical dust-precipitator of present use, has the efficiency of dust collection height, does not produce reentrainment of dust, advantage such as maintain and replace is simple, is applicable to the dedusting of high concentration dusty gas.This dust-precipitator is combination cyclone dust collection principle, but because of the whirlwind tube each be one independently individual, so that system leaks out is bigger, influence the stable operation of cottrell.Because aid distributing pipe is arranged, make the total complexity.
Also few the research that gravity gathers dust, the principle combination is carried out in cyclone dust collection, cottrell at present.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of collection gravity, cyclone dust collection is in the vertical electrostatic precipitator of one, this device is by improving the structure of gravity cyclone dust collection part, the lower housing portion cavity is passed through the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind intercepts into one-level gravity settling chamber and secondary gravity settling chamber with damping sheet, and be obliquely installed whirlwind to be distributed in the one-level gravitational settling indoor a plurality of, this structure efficient set gravitational settling, cyclone dust collection, so in principle, it is gravitational settling, cyclone dust collection, three grades of series connection of gravitational settling, so dust-collecting efficiency height, secondly again because the sub-size of single whirlwind is little, cyclone dust collection efficient height, total dust-collecting efficiency improves.The other advantage of this structure is that a plurality of whirlwind are in parallel, and in the housing that exists together, can increase with whirlwind quantum count number so handle air quantity.And the system radiating area reduces, and system radiating is reduced, and entire equipment also has the dust-collecting efficiency height, and operating cost is little, the advantage that floor space is little.
The technical solution adopted in the present invention is: a kind of collection gravity, cyclone dust collection is in the vertical electrostatic precipitator of one, comprise and have air inlet, the housing of clean gas outlet, housing internal upper part cavity is provided with the electric precipitation part, lower cavity is provided with gravity cyclone dust removal part in the housing, the air outlet of gravity cyclone dust removal part partly is connected with electric precipitation, bottom at housing also is provided with ash hole, described gravity cyclone dust removal partly comprises gravity settling chamber and is arranged on indoor whirlwind of gravitational settling, described gravity settling chamber is by the sub-upper face plate of whirlwind, the sub-lower face plate of whirlwind and the damping sheet cavity that gravitational settling is indoor is divided into one-level gravity settling chamber and secondary gravity settling chamber, air inlet is connected with described one-level gravity settling chamber, and ash hole is connected with described secondary gravity settling chamber;
