Description
Technical field
The utility model relates to a kind of dust arrester, especially a kind of fume dust remover.
Background technology
Dust arrester, is commonly called as deduster, is the device of removing or reduce fly ash content in flue gas.The kind of dust arrester can be divided into bag-type dust collector, cyclone dust collector, wet dust separater, electrostatic precipitator, desulfation dust-extraction device.Be widely used in the industry such as chemical industry, oil, metallurgy, building, mine, machinery, light textile.
The kind of dust arrester can be divided into bag-type dust collector, cyclone dust collector, wet dust separater, electrostatic precipitator, desulfation dust-extraction device.Domestic common electrostatic dust collection equipment pattern can roughly be divided into following a few class at present: by airflow direction, be divided into vertical and horizontal, by receiving electrode polar form formula, be divided into board-like and tubular type, sweep-out method by dust on precipitation pole plate is divided into dry type wet type, rotary-umbrella-type high-efficiency electric dust catcher and Mo machine special high-pressure electrostatic precipitator etc.Purposes: the granule dust in separation industries waste gas and fine solid particle, be widely used in metallurgy, mine, cement, steam power plant, building materials, casting, chemical industry, tobacco, asphalt mixture machine, grain, machining, boiler dusting, cement slurry, grog grinding machine, furnace cupola etc.Existing electrostatic precipitator, cannot be to all dust Electrostatic Treatment when dust is larger, and dedusting was handed over undesirable.
Utility model content
Technical problem to be solved in the utility model is for the deficiency of above-mentioned background technology, and fume dust remover is provided.
The utility model adopts following technical scheme for realizing above-mentioned utility model object:
Fume dust remover comprises housing, is placed in the ash bucket that of housing bottom, described in go out on ash bucket sidewall to have smoke inlet, be placed in the exhanst gas outlet of case top,
In housing, layout has the first electrode group, the second electrode group, tank from bottom to top, described the first electrode group,
The second electrode group is connected in series, and described tank upper section is communicated with described exhanst gas outlet, and described tank lower section is communicated with described the first electrode group top.
In described fume dust remover, the first electrode group, the second electrode group structure are identical, comprise and are placed in the collecting electrode plate of electrode group outer wall, cylindric metal electrode.
In described fume dust remover, the center of cylindric metal electrode in collecting electrode plate institute region.
In described fume dust remover, tank is the large trapezoidal flume of the little lower section of upper section.
In described fume dust remover, exhanst gas outlet inwall is symmetrically arranged with deflector..
The utility model adopts technique scheme, has following beneficial effect.
Accompanying drawing explanation
Fig. 1 is the structure chart of fume dust remover.Number in the figure explanation: 1, exhanst gas outlet, 2, tank, the 3, first electrode group, the 4, second electrode group, 5, ash bucket, 6, deflector, 7, collecting electrode plate, 8, cylindric metal electrode, 9, smoke inlet.
The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme of utility model is elaborated:
Specific embodiment one: fume dust remover, comprise housing, what be placed in housing bottom goes out ash bucket 5, go out on ash bucket 5 sidewalls and have smoke inlet 9, be placed in the exhanst gas outlet 1 of case top, in housing, layout has the first electrode group 3 from bottom to top, the second electrode group 4, tank 2, the first electrode group 3, the second electrode group 4 is connected in series, tank 2 upper sections are communicated with exhanst gas outlet 1, tank 2 lower sections are communicated with the first electrode group 3 tops, the first electrode group 3, the second electrode group 4 structures are identical, comprise the collecting electrode plate 7 that is placed in electrode group outer wall, cylindric metal electrode 8, the center of cylindric metal electrode 8 in very small region that collecting electrode plate 7 encloses.
Specific embodiment two: on the basis of embodiment mono-, tank 2 is the large trapezoidal flume of the little lower section of upper section.
Specific embodiment three: on the basis of embodiment mono-or embodiment bis-, exhanst gas outlet 1 inwall is symmetrically arranged with deflector 6..
The fume dust remover of specific embodiment one, flue gas enters dust arrester from smoke inlet 9, the first electrode group 3, the second electrode group 4 is after connecting high-tension electricity, collecting electrode plate 7, between cylindric metal electrode 8, produce non-uniform electric field, the great electric field of field intensity collecting electrode plate 7 produce corona discharge in enclosing very small region, enter collecting electrode plate 7 and enclose the flue gas generation ionization generation ion electronics in very small region, anion collides with the soot particle flowing through in flue gas in the process to collector plate 7 motions, make soot particle with negative electrical charge, soot particle with negative electrical charge gathers on collector plate 7, flue gas is through the first electrode group 3, twice Electrostatic Treatment of the second electrode group 4 gone out the most of flue dust in flue gas, the flue dust not being ionized for small part enters tank and filters, flue gas after final purification is discharged from exhanst gas outlet 1, the electronegative soot particle being gathered on collector plate is discharged from ash bucket 5.
In specific embodiment two, the trapezoidal flume that the little lower section of upper section is large is conducive to increase the contact-making surface of flue gas and water, improves purification efficiency.
In specific embodiment three, deflector has improved flow of flue gas uniformity, improves efficiency of dust collection.
In sum, fume dust remover described in the utility model has higher efficiency of dust collection.
