Description
Technical field
The present invention relates to a kind of high-performance device of industrial waste gas purifying, especially relate to a kind of device that improves electric cleaner efficient and reduce the bag dust collector resistance.
Background technology
The economic construction high speed development of China; the people's living standard improves constantly; society is also more and more higher to requirement on environmental protection; new national standard " thermal power plant's pollutant emission standard " is implemented; require flue dust the highest permission concentration of emission in coal-burning power plant's under the mark condition, to reduce to 50mg/Nm3, the capital equipment-cleaner of atmosphere pollution is faced huge pressure as particle in the control thermal power plant from original 200mg/Nm3.Both at home and abroad the high-effective dust-removing equipment of generally acknowledging is electric cleaner and sack cleaner, particularly electric cleaner, advantage such as it is little with its efficiency of dust collection height, resistance, convenient operating maintenance and occupied most of dedusting field of the world today.The coal that uses high ash content, low sulphur content more than 50% is arranged in China coal-burning power plant, can cause deduster inlet flue gas dust content to raise, flue dust becomes big than resistance, is unfavorable for that electric cleaner gathers dust.For sack cleaner, because dust content is higher, SR is bigger, has shortened the service life of filtrate on the one hand greatly, on the other hand, has increased operating cost, has restricted the extensive use of sack cleaner.
Early stage electric cleaner or bag dust collector equipment are because discharging standards requires lower, type selecting is less, performance descends, do not reach the requirement of new standard, must transform it, but because the place is arranged limited, when various ways such as increase electric field cannot realize, just can in its preposition flue, install this device, improve the resistance of electric cleaner efficient or reduction bag dust collector, to reach the discharge standard of national requirements.
Both at home and abroad to life science studies show that PM10 and PM2.5 airborne fine particulate matter not only influence weather and air quality, destroy ecological environment, and the serious harm human respiratory, even be inhaled into blood, accumulate in vivo for a long time.Compare with thicker Atmospheric particulates, the PM2.5 particle diameter is little, contain a large amount of poisonous, harmful substance, and the time of staying in atmosphere is long, fed distance is far away, thereby bigger to the influence of health and atmosphere quality.Can cause mammalian cell generation vicious transformation, cause that cell DNA fracture, chromosome damage, cell-cell communication suppress, therefore can think, fine particle can damage respiratory function, cause inflammation, respiratory disease such as asthma, make the dangerous increase of the cardiopathic illness rate and the death rate, and have potential carcinogenicity.
Adopt impact type grit grading instrument that thin ash before and after the pulverized-coal fired boiler electric cleaner is formed and measure, studies show that the ratio that PM10 and PM2.5 behind the deduster account for total ash is 92.47% and 35.56%, than all being improved largely before the deduster.Deduster is not high to thin grey arresting efficiency, and the PM2.5 efficiency of dust collection is 90.6%.
Existing similar patented technology, efficient is not high, and the electric power system control performance is bad, does not increase in the rough system at particle cluster and powers, and it is not high that particle increases the rough system performance, can not be that the mixing fully of charged particle group increases thick.
Summary of the invention
The purpose of this utility model is a kind of device of design, to PM10 and the following dust efficiency of dust collection of PM2.5 is not high, the sack cleaner running resistance is higher defective, provide a kind of device that improves electric cleaner efficient and reduce the bag dust collector resistance at existing electric cleaner.
In order to achieve the above object, the technical solution of the utility model is: the utility model is made up of preposition flue and coupled electric cleaner (or sack cleaner) and chimney, is provided with water conservancy diversion frictional electricity system, anode and cathode electric power system, alternation electric power system and particle and increases rough system four parts in preposition flue.Described anode and cathode electric power system comprises that anode, negative electrode and earthing pole form.The electric power system of the utility model positive or negative high voltage, positive high voltage, negative high voltage, ground connection have the ion generation system of three polarity, and the particle cluster with the supply of alternation energy increases system.
The utility model compared with prior art, having following tangible advantage and innovation (1) the utility model is a kind of device that improves electric cleaner efficient and reduce the bag dust collector resistance, adopt the electric power system of positive or negative high voltage, the ion generation system of positive high voltage, negative high voltage, three polarity of earthing pole, the particle cluster with the supply of alternation energy increases system.Water conservancy diversion frictional electricity device is arranged in the front portion of described device.Has one group of ion generating device at least.Adopt the device of particular design in the ion generation system, abundant ion can take place, so that dust is charged.Rear portion at device has particle to increase rough system, can be that the mixing fully of positive and negative particle cluster increases slightly, improves the resistance of follow-up electric cleaner efficient or reduction bag dust collector.(2) follow-up equipment is if electric cleaner can be removed the dust stratification on positive plate and the cathode line under the situation of less rapping power.If bag dust collector can improve filtration velocity, reduce the floor space of equipment, can reduce the resistance of equipment, prolong the service life of filter bag.Can improve the arresting efficiency of deduster, reduce the discharging of PM10 and PM2.5 greatly subparticle.(3) contain the water conservancy diversion frictional electricity system of particular design in this device, when the logical high-tension electricity of this device, just can promote the efficient of follow-up electric cleaner.
The utility model is applicable to the elimination of dust contamination in fields such as electric power, metallurgy, building materials, chemical industry, reduces the discharging of PM10 and PM2.5 and following particle, for harmful heavy metals such as removing mercury very high efficient is arranged also.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
