Description
Technical field
The present invention relates to a kind of dust arrester.
Background technology
Deduster is generally by the various dusts that industrial sites produces, and such as normal dust, zinc oxide, wood, stone, raw cotton, cereal, fur and lead powder separate with air, and the clean air of free from dust is discharged into air, makes air can not by contamination by dust.These dedusters are categorized into electron type and filter type according to their dust collecting methods, and electric cleaner utilizes electric polarity to be separated from air by dust, and filter-type deduster utilizes filter webs to be separated from air by dust.
The principle of the two poles of the earth work that the electrostatic precipitator generally used at present adopts cathodic discharge, anode gathers dust, also exists following deficiency: 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.Continuous accumulation makes the adhesive force of grit antianode increase, and not easily shakes and forms high resistivity dust layer.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.Therefore for high resistivity dust, need to adopt modified and spraying process, and operational efficiency is still undesirable.
And, due to improving constantly of environmental emission standard now, the 100mg/m of existing electric cleaner
3and 50mg/m
3concentration of emission can not adapt to current environmental emission standard.People have got down to the improvement of electric cleaner.Existing two kinds of improved procedures are generally: the efficiency of dust collection improving electric cleaner by improving electric-field intensity (namely improving voltage of electric field); The efficiency of dust collection of electric cleaner is improved by increasing electric field quantity.But the raising of electric-field intensity makes same die opening improve, thus cause the lock-on range of dust to increase, and according to the computing formula of Coulomb force, Coulomb force and square to be inversely proportional to anode-cathode distance, therefore, the raising of electric-field intensity catches the impact of power also not quite to dust; In addition, improve electric-field intensity and also improve the electric field class of insulation, thus bring certain difficulty to the manufacture of electric cleaner; Finally, that improves that electric-field intensity not only increases electric cleaner realizes cost, adds manufacture difficulty, and, also make the efficiency of dust collection of electric cleaner not obtain substantive raising.And increase the improved procedure of electric field quantity, what greatly improve electric cleaner undoubtedly realizes cost.
Summary of the invention
In view of this, the object of the invention be to provide a kind of when ensure electric cleaner have lower realize cost and lower manufacture difficulty, a kind of dust arrester of the efficiency of dust collection of the raising electric cleaner of high degree.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of dust arrester, comprise dirt pocket, be connected to the dust gathering arrester of described dirt pocket lower end, and be arranged on the air inlet of described dust gathering arrester side, be provided with multiple spaced collecting plate in described dirt pocket, in this collecting plate, be provided with corona discharge electrode, wherein said collecting plate each other and described collecting plate and described dirt pocket inner surface each other uniform intervals be provided with some baffle plates, described baffle plate extends radially outwardly along described collecting plate, and along the axially interlaced setting of described collecting plate; Described dirt pocket upper end uniform intervals is provided with multiple air outlet, and described air outlet is equipped with two ventilating ducts, and this ventilating duct is respectively air intake passage and backwash passage, and this ventilating duct is connected with a blower fan.
Preferably, above-mentioned a kind of dust arrester, wherein said air intake passage is provided with suction control valve, and described backwash passage is provided with backwash control valve.
Preferably, above-mentioned a kind of dust arrester, is also provided with a Venturi tube between wherein said air inlet and described dust gathering arrester, and the venturi place of described Venturi tube is connected with a pressurized water source.
Preferably, above-mentioned a kind of dust arrester, wherein said air inlet and described dust gathering arrester junction are provided with filter course.
Preferably, above-mentioned a kind of dust arrester, diffuser and the described dust gathering arrester junction of wherein said Venturi tube are provided with filter course.
Preferably, above-mentioned a kind of dust arrester, wherein said air outlet place is provided with wind-proof dust-suppression net.
Preferably, above-mentioned a kind of dust arrester, wherein said dust gathering arrester lower end is connected with a fixing rotary soot blower.
Technique effect of the present invention is mainly reflected in: in this dust arrester collecting plate each other and collecting plate and dirt pocket inner surface each other uniform intervals be provided with some baffle plates, baffle plate extends radially outwardly along collecting plate, and along collecting plate axially interlaced setting, it efficiently utilizes collecting plate gap each other and the gap of collecting plate and dirt pocket inner surface, when dusty gas becomes vertical direction inflow device with certain speed with baffle plate, grit is impact baffle plate first, and lands due to gravity.The more small grit flowed in company with air-flow impacts on another baffle plate, settles out with same principle.Such dusty gas is due to the repeatedly barrier effect of baffle plate, and with different curvature radius switching flows direction, the grit in dusty gas is under the effect of inertia force and centrifugal force and be captured.Dirt pocket upper end uniform intervals is provided with multiple air outlet simultaneously, and air outlet is equipped with two ventilating ducts, and this ventilating duct is respectively air intake passage and backwash passage, and this ventilating duct is connected with a blower fan, can be cleaned dirt pocket at any time by backwash passage.
