Description
Technical field
The present invention relates to field of environment engineering, particularly relate to a kind of wet electrical dust precipitator anode.
Background technology
China is while rapid economic development, and the improvement of pollutant is very urgent, and haze is the pain in each Chinese people especially Jing-jin-ji region people mind that hovers in recent years.Sulfur dioxide, nitrogen oxides and pellet are mainly comprising of haze.The suspended particulate substance of different-grain diameter in haze, can cause different impacts to health.Granule is the thinnest, and the chance being inhaled into is the biggest, and the activity in human body is the strongest, and the harm to human body is the biggest.Due to taking place frequently of haze weather, air contaminant treatment industry standard, national standard are stepping up, the proposition of near-zero release concept the most in recent years, and most enterprises is all close towards this direction, and dust concentration effectively controls, and relies on efficient cleaner.
Ecological environmental protection is still by as one of " 13 " High-Interest Object in period task, and wherein haze is administered is emphasis.
Industrial smoke not qualified discharge is the most important source that current China haze produces, and steel industry is as polluting one of the most serious industry, and its standard limit of smog release ratio is relatively low, and implementation dynamics is the most poor.Along with country's increasing to contaminating enterprises' control dynamics, the discharge standard of steel industry is also stepping up.In new discharge standard, sintering machine head end (pelletizing) particulate matter New emission standard is 50mg/m3, special emission limit is 40mg/m3.The most not installing wet electrical dust precipitator additional after China's wet desulphurization facility at present, granular material discharged concentration typically can only achieve 50～80mg/m3.The particulate matter New emission standard limit value of iron and steel enterprise's raw material system, sintering machine tail, blast furnace casting factory, blast furnace ore tank, converter secondary flue gas and other dusts point is at 10-30mg/m3, but the design concentration of emission of most of iron and steel enterprises dust pelletizing system is at 30-50mg/m3。
Owing to the desulfuration efficiency of wet desulphurization is high, existing more than 500 platforms sintering (pelletizing) equipment of current China use wet desulfurizing process, and the multi-pollutant such as fine particle to be met, two English works in coordination with the requirement of removal, must supporting wet electrical dust precipitator after desulfurization.
Current existing wet electrical dust precipitator has, such as Chinese patent: ZL201420674323.4U " a kind of wet type cellular electrostatic precipitator negative electrode holder hot air sweeping device "；CN 201510674030.5 " high-efficient wet-type electric cleaner "；CN204074267U " wet electrical dust precipitator anode unit "；ZL201520135634.8 " a kind of corrugated wet scrubber anode "；ZL201520155371.7 " a kind of wet electrical dust precipitator anode "；ZL201520224658.0 " a kind of cellular bamboo slab rubber wet-esp anode ".
Current wet scrubber has flexible anode and rigid anode two kinds.Flexible anode is mainly based on sack cleaner, and sack cleaner exists easily to be electrically shocked to be worn, and the situation about hardening on cloth bag surface easy to stick Han moist big dust.Rigid anode is mainly based on fiberglass, but fiberglass is expensive, and weight is big, perishable.Owing to cellular rigid anode effective area is big, system stability, the most current wet electrical dust precipitator is mainly based on cellular, but cellular anode exists easily at six angle dust stratifications, and the problem being not easily cleaned, thus affects dust removing effects.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wet electrical dust precipitator anode, thus solves that current wet electrical dust precipitator weight is big, perishable, price is high, easily form the problems such as dust stratification dead angle in angle.
This wet electrical dust precipitator anode is made up of more than one anode unit, and wherein, anode unit is six limit alveolate textures, and anode unit is coated with plated carbon fiber by polyvinyl fluoride top layer and makes, and carbon fiber employing plating, the mode coating or suppressing are coated with and are plated on anode unit.
The polyvinyl fluoride thickness making anode unit is 0.3-3.0mm, a length of 1-15m, and anode unit hexagonal side length is 100-350mm；Carbon fiber is coated with and is plated on two surfaces up and down of anode unit, and is monolayer coating, and coating layer thickness is 0.1-1mm.
The most important thing is, the angle of anode unit is not coated with plated carbon fiber, and the two ends of hexagon each edge are not coated with the length of plated carbon fiber and are the 1/10 of hexagonal side length.
Cleaner unit is all had a great impact by polyvinyl fluoride plate length, thickness and the hexagonal side length of honeycomb texture.After considering dust removing effects, the stability of equipment, the composite factor such as economical, the length of polyvinyl fluoride plate, thickness and hexagonal side length are both needed to control effectively.
Polyvinyl fluoride length is the shortest, and the anode unit of needs is the most, more increases duster system resistance, increases energy consumption, thus reduce the dust removing effects of cleaner unit；Polyvinyl fluoride length is the longest, then system is more susceptible to shake, closer to flexible anode, and electric field and to rush ash the most uneven, thus affect the stability of total system, extremely it is susceptible to anodic breakdown phenomenon, is substantially reduced dust removing effects.Finding through repetition test and computer simulation, polyvinyl fluoride plate length not can exceed that 15m, once more than 15m, the vibration frequency of anode strengthens, and its stability exponentially declines, and polyvinyl fluoride version length cannot be below 1m, during less than 1m, SR increases 2 times, and energy consumption increases by more than 2 times.
The polyvinyl fluoride plate hexagonal side length of honeycomb texture also ensures a big factor of wet electrical dust precipitator dust removing effects and stabilization of equipment performance.Finding through repetition test and computer simulation, polyvinyl fluoride plate hexagonal side length determines the size of discharge voltage, and the length of side is the shortest, and the anode unit of needs can be greatly increased, and SR strengthens, and energy consumption increases；And polyvinyl fluoride plate hexagonal side length oversize time, cathode capacitance volume strengthen, potential safety hazard increases.Find through repetition test and computer simulation, when polyvinyl fluoride edges of boards length is more than 350mm, cathode capacitance needs to be multiplied to can be only achieved identical electromagnetic field intensity requirement, when the length of side is 360mm, cathode capacitance is 5 times during 350mm, cost increase is to 3.5 times during 350mm, and the processing safety of workman is also greatly reduced.Polyvinyl fluoride edges of boards length less than 100mm time, SR is the most in exponential increase, when the length of side is 80mm, SR be the length of side be 3 times during 100mm, energy consumption be the most accordingly the length of side be 3 times during 100mm.Therefore polyvinyl fluoride edges of boards length is selected to control at 100-350mm.
Polyvinyl fluoride plate thickness determines the stability of the cost of wet electrical dust precipitator, life-span and whole system.The least cost of thickness is the lowest, but easily by electric field breakdown when thickness is the least, and system is susceptible to vibrations, therefore selects suitable thickness most important.Finding through repetition test and computer simulation, polyvinyl fluoride plate thickness should control at 0.3-3mm, when thickness is less than 0.3mm, polyvinyl fluoride plate is due to the thinnest, wind-force reaches to begin to when 5 grades slosh, thus causes electric field and uneven, is very easy to punch-through；And when thickness is more than 3mm, the strong wind of 8 grades can be resisted, it is contemplated that the overall cost of positive plate and the climate characteristic of non-coastal area, the maximum gauge of polyvinyl fluoride plate has been selected in 3mm.
Alveolate texture is the most rational anode plate structure generally acknowledged at present, but cellular six angle fouling phenomenons are the problems that each wet electrical dust precipitator applies that producer compares headache.In order to avoid angle dust stratification, some cleaner unit producers use arc-shaped angle, or the clear-cut cylinder type anode that uses, but the alveolate texture of circular arc angle makes complexity so that the cost of positive plate is greatly increased；Although and the pole plate of cylinder type solves Cost Problems, but dust stratification area is greatly lowered, and system stability also reduces a lot.Therefore the present invention uses angle not spray conductive layer to solve the easy dust stratification of angle and the problem being not easily cleaned.Find through computer simulation and repetition test: each angle accounts for the place of the length of side 1/10 when not spraying conductive layer, and under identical voltage condition, long run test one month, the total amount of trap dust does not reduce, and has had small size rising on the contrary.This is owing to angle no longer dust stratification hardens, though effectively trap dust area reduces in theory, but the time of deashing shortens, and the most actually active trapping area increases on the contrary.
Having the beneficial effect that of the technique scheme of the present invention:
In such scheme, use polyvinyl fluoride material rigid anode for the shortcoming of current wet scrubber anode, solve that current rigid anode resistance to elevated temperatures is poor, corrosion resistance is low, cost is high, weight is big, laying dust effect is low, easily in problems such as angle dust stratifications.
