Description
Technical field
The present invention relates to a kind of combined type runoff electric cleaner.
Background technology
PM2.5 refers to that in atmosphere, diameter is less than or equal to the particle of 2.5 microns, also referred to as entering lung particle.Although PM2.5 is content component seldom in earth atmosphere composition, it has important impact to air quality and visibility etc.PM2.5 particle diameter is little, is rich in a large amount of poisonous and harmful substances and the time of staying in atmosphere is long, fed distance is far away, thereby larger on the impact of health and atmosphere quality.Weather scientist and medical expert think, the haze weather being caused by fine particle is even larger than sandstorm to the harm of health.10 microns of above particles of particle diameter, can be blocked in outside people's nose; The particle of particle diameter between 2.5 microns to 10 microns, can enter the upper respiratory tract, but part can excrete by sputum etc., also can be stopped by the fine hair of nasal cavity inside in addition, relatively little to human health damage; And particle diameter is at the fine particle below 2.5 microns, diameter is equivalent to human hair's 1/10 size, is difficult for being blocked.After being inhaled into human body, can directly enter bronchus, disturb the gas exchange of lung, cause the disease that comprises the aspects such as asthma, bronchitis and cardiovascular disease.Everyone on average will suck the air of approximately 10,000 liters every day, and the micronic dust that enters alveolar can be absorbed rapidly, without liver detoxification, directly enter blood circulation is distributed to whole body; Secondly, can damage the ability of hemoglobin delivery of oxygen, lose blood.Concerning the patient of anaemia and blood circulation disorder, may produce serious consequence.For example can increase the weight of respiratory disease, even cause the heart diseases such as congestive heart failure and coronary artery.These particles can also enter blood by bronchus and alveolar in a word, and pernicious gas wherein, heavy metal etc. are dissolved in blood, larger to the injury of health.The physiological structure of human body has determined PM2.5 without any filtering, obstruction ability, and PM2.5 progress along with medical technology to the harm of human health, progressively exposes the one side of its terror.
Existing electric cleaner, because the distance between positive and negative pole plate is larger, the particle that causes diameter in flue gas in power station boiler to be less than or equal to 2.5 microns in air-flow, be not also able to do in time motion, be attached on positive and negative pole plate, just by air-flow with having passed positive and negative pole plate, if reduce air-flow through the speed of battery lead plate, the treatable throughput of electric cleaner can significantly reduce, and is difficult to meet the required processing requirements of production.Therefore, existing electric cleaner cannot meet the designing requirement of removing dust very tiny in large flow gas, and the Dust Capacity in its flue gas of discharging is generally more than 70 milligrams/cubic metre, and most dust of discharging all belong to can enter lung particle.Traditional electric cleaner is when giving the supporting dedusting of power plant boiler, normally adopt the series connection of 3-5 group electric cleaner to use, it is large-minded that it has interior processing of unit interval, remove the good feature of dust effect of larger particles, but along with country improves constantly the environmental protection standard of the flue gas of power plant's discharge, even the technical scheme of taking the series connection of 3-5 group electric cleaner to use, also be difficult to a large amount of these class fine dusts of PM2.5 that exist in the flue gas of discharge effectively to be got rid of, owing to cannot efficiently removing PM2.5, cause a large amount of electricity generation boiler of China to be difficult to meet new boiler of power plant smoke evacuation environmental protection standard.
