Description
Technical field
The utility model belongs to environmental protection, dedusting technology field, relates to a kind of device of eliminating haze.
Background technology
Chinese haze weather was more and more in recent years, and PM2.5 concentration is increasing, and haze has had a strong impact on people's physical and mental health; These three of sulfur dioxide, nitrogen oxide and pellets are haze chief components, the above two are gaseous contaminant, last particle is only and increases the weight of the arch-criminal that haze weather pollutes, and they and fog combine, and allows sky moment become gloomily gloomy.
The method of current existing elimination haze and dust can be summed up as following several:
A, filtration method.By the air intake dust arrester that contains particle, by water or other media, filter, reach the object purifying air; The suitable particle of eliminating among a small circle of the method, is not suitable for implementing on a large scale, and the method need, by the air intake dust arrester that contains particle, be filtered all air.When overanxious, if filter mesh is excessive, can cause too much particle by mesh, purify not thorough; If filter mesh is too small, while causing air to pass through screen pack, resistance is excessive, and efficiency is low.
B, water droplet absorption method.By spray the easily particulate catalyst of adsorption moisture such as salt, urea in air, this type of catalyst becomes moistening after absorbing airborne moisture, airborne dust granules thing runs into moistening catalyst can stick to its surface, particle becomes heavy after assembling, last sedimentation on the ground, reaches the object of eliminating particulate in air.The method is applicable to eliminating airborne particle on a large scale, but efficiency is lower, and need possess certain condition: air will reach certain humidity, makes catalyst become moistening.Yet in the more area of haze weather, North City is in the majority, and winter is more serious, and the winter air of North City is generally drier, needs air to reach certain humidity and just can implement, and has limitation and passivity; In addition, when dedusting, only have when airborne particle " is encountered " little water droplet and just can adhere to, belong to passive adhesion, efficiency is not high.
Except sprinkling catalyst method as above, also have the methods such as rain making, this type of Method And Principle is similar, does not enumerate one by one here.
C, Cottrell process.Cottrell process is a kind of of dedusting method, and dusty gas is separated by electricity during through high-voltage electrostatic field, and grit be combined with anion and is with after upper negative electricity, tends to anode surface and discharges and deposit.In the industry such as metallurgical, chemical in order to Purge gas or reclaim useful grit.Thereby utilize electrostatic field to make gas ionization make dust particles be adsorbed onto the dust collection method on electrode.In highfield, air molecule is ionized as cation and electronics, and electronics marches on towards in anodal process and runs into grit, and the electronegative positive pole that is adsorbed onto of grit is collected.Certainly, in recent years by technological innovation, also there is the mode that adopts negative plate control of dust.Factory, power station that to be usually used in take coal be fuel in the past, collect coal ash and dust in flue gas.In metallurgy, for collecting the oxide of tin, zinc, lead, aluminium etc., now also having can be for the dust cleaning and sterilizing product of household.When dedusting, need two relatively close charged pole plates to form electric field, pole plate distance can not be too far away, is in this way not suitable for implementing on a large scale.
