Description
Technical field
The utility model is a kind of deduster, particularly a kind of electric-bag complex dust collector.
Background technology
Along with improving constantly of socioeconomic develop rapidly and living standards of the people, problem of environmental pollution is more and more subject to concern and the attention of country.Wherein the smoke contamination emission numerical value of coal-burning power plant's generation is surprising, and PM2.5 is the principal element affecting urban air quality and visibility, and the serious harm people's is healthy.Rise on January 1st, 2012 " the large pollutant emission standard of thermal power plant " of execution, require that coal-burning power plant reaches≤30mg/m3, some developed provinces and cities are as requirement≤20mg/m3 such as Beijing, Shanghai, Guangdong in addition.So coal-burning power plant must take efficient, stable dedusting technology, effectively to control the soot emissions of trace.
Summary of the invention: the 1980s rises, electric cleaner becomes the first-selection of China's coal-burning power plant's cleaner, and its principle utilizes dust charged in the electric field and deposits to electrodes for removing dust under electric field force effect.Electric cleaner has that running resistance is low, system pressure loss is little; Equipment can bear high temperature impact; Core component is steel construction, long service life; The advantages such as operation maintenance workload is little.But electric cleaner is undertaken designing by certain coal, and due to the impact of a variety of causes, in boiler running process, the coal-fired condition of use can vary widely.Therefore, cause the efficiency of dust collection of electric cleaner that very large fluctuation may occur, affect dust removing effects.Its installation cost and power consumption also sharply increase thereupon, make electric cleaner be faced with the contradiction that flue gas condition is more and more uncertain and emission request is more and more higher.
Sack cleaner be utilize fibrous braid to make bag-like filter element to trap the solid particulate matter in dusty gas.Its feature: efficiency of dust collection is stablized, do not affected by coal, and outlet drain generally can ensure≤30mg/m3.But sack cleaner can accomplish lower discharge just putting into operation in a period of time, but be difficult to maintenance and run reliably and with long-term.Meanwhile, its running resistance is large, and blower fan power consumption is higher, and the filter material replacement cycle is short, all considerably increases maintenance cost.
Summary of the invention
The utility model mainly solves the deficiencies in the prior art, compact conformation, the mechanism of electric-bag complex dust collector utilizes the high-effective dust-removing performance of prime 1-2 electric field first to collect volume of smoke in flue gas, the a small amount of flue dust be not collected is by after electric-field charge, enter rear class filter bag dedusting area, complete filtration by filter bag and reach the object of purifying smoke, gathering dust and charged effect by electric field, improve the condition of work of filter bag and improve the overall performance of equipment, this combine with technique feature performance benefit of electric precipitation and bag-type dusting, essence solve coal fired power plant face flue gas condition difference and require high contradiction with gathering dust, become the electric-bag complex dust collector of the preferred energy-efficient new cleaner of big-and-middle-sized unit in coal-burning power plant from now on.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of electric-bag complex dust collector, comprise dust-removing box, filter bag is provided with in described dust-removing box, equally distributed cathod system is provided with in described filter bag, described cathod system is supported by gripper shoe mutually with filter bag, equally distributed air-vent is provided with in described gripper shoe, the pulse blowing pipe of distribution corresponding with cathod system is provided with in the upper end of described dust-removing box, the bottom of described dust-removing box is provided with ash bucket, the bottom of described ash bucket is provided with detachable discharging opening, the outer wall of described ash bucket upper end is provided with vibrator, humidity sensor is provided with in described dust-removing box.
As preferably, the inwall of described dust-removing box is provided with heater, the distribution corresponding with filter bag of described heater.
Technical characteristics: 1, low emission steady in a long-term: electric-bag complex dust collector adapt to coal, the change of flue dust ratio resistance ability strong, outlet drain concentration is low, can meet≤the requirement of 30mg/m3 for a long time, efficiently, stably.2, running resistance is low: due to the effect of electric field region, and the dust concentration entering filter bag district flue gas stream significantly reduces.Meanwhile, these dust are subject to repulsive force between electric charge and different in nature electrostatic coagulation effect, and reduce micronic dust and pierce or embed pocket type layer and increase filter bag residual resistive.3, life-span of the filter bag is long: electric-bag complex dust collector due to filter bag district dust contained flue gas concentration low, it is again Charged, so its deashing pressure low (general 0.2-0.25mpa), cleaning cycle long (general 2500-600s), simultaneously not by the erosive wear of the thick power particles such as silica.Therefore, life-span of the filter bag extends greatly than conventional sack cleaner.4, energy-conservation obviously, operation and maintenance cost is low: electric-bag complex dust collector energy-conservation mainly through following three aspect: A because electrostatic fabric filter resistance to save the power consumption of blower fan lower than conventional sack cleaner; The B filter bag ash removal cycle is long, can save the power consumption of air compressor machine; C electric field configuration number of power sources, compared with traditional electrical deduster, is only about 1/4th, therefore greatly saves electric energy.
Therefore, the electric-bag complex dust collector that the utility model provides, compact conformation, steady in a long-term, low emission, running resistance is low, and life-span of the filter bag is long, obvious energy conservation, and operating cost is low.
