Abstract
The present invention discloses one kind and removing haze method based on the oversaturated coring of steam, and this approach includes the following steps：A. ultra micro air water mist is generated by spraying system；B. ultra micro air water mist is sprayed into atmospheric environment, by temperature-fall period so that using haze particle being the particle that core forms that supersaturation and condensing to form 10 microns or more in atmospheric environment, passes through the gravitational settling removing haze of 10 microns or more particles.The efficiency for removing PM2.5 except haze method improves based on the oversaturated coring of steam of the present invention, even can reach 95% or more within the enclosed space.This method, which can also be generalized to, removes the high concentration particles pollutant fields such as emission source.The present invention's has the advantages that method is simple, efficient, lower-cost except haze method based on the oversaturated coring of steam.
Description
Technical field
The invention belongs to environmental technology fields, and in particular to one kind removing haze method based on the oversaturated coring of steam.
Background technology
Haze is the general designation of the fine droplet to suspend in air and fines object, with the hair at full speed of human social economy
Exhibition, the haze weather occurred on a large scale have seriously affected the healthy living of the mankind.It is main about the research of haze both at home and abroad at present
Haze origin mechanism, haze particle Microphysical Characteristics and chemical composition etc. are concentrated on, and effectively administers the exploration phase of haze means
Less and elimination efficiency is extremely limited.
Invention content
Technical problem to be solved by the invention is to provide one kind removing haze method based on the oversaturated coring of steam.
The present invention based on the oversaturated coring of steam except haze method includes the following steps：
A. ultra micro air-water mist is generated by spraying system；
B. ultra micro air-water mist is sprayed into atmospheric environment, by temperature-fall period so that using haze particle as core in atmospheric environment
It forms supersaturation and condenses to form 10 microns or more of particle, the gravitational settling for passing through 10 microns or more particles removes haze.
Ultra micro air-water mist is that the D50 values of grain size Spectral structure are less than 15 microns, water mist of the D90 values less than 25 microns, described
D50 values refer to the grain size of 50% or more water particle at 15 microns hereinafter, the D90 values refer to the grain of 90% or more water particle
Diameter is at 25 microns or less.
Spraying system in step a is single-phase high voltage nozzle, vapor-liquid two phases nozzle, effervescent atomizer or ultrasonic atomizatio
It is one or more of in nozzle.
Temperature-fall period in step b is Temperature fall, ultra micro air-water mist evaporative cooling or artificial sprinkling refrigerant cooling
In it is one or more of.
Atmospheric components can stable for extended periods of time, among these the self-cleaning mechanisms play of air itself conclusive effect,
Such as natural rainfall, snowfall, dense fog etc..In the process, in the case that air basic humidity is enough, cooling causes in air
Steam it is supersaturated " precipitations " by the nuclei of condensation of haze particle, and realize that grain size increases and settles by further absorbing steam, from
And realize effective wet removing to haze.
The coring for being based on aerosol in nature except haze method based on the oversaturated coring of steam of the present invention is wet clear
Except mechanism, air humidity is quickly increased by spraying system, by temperature-fall period, air humidity is made to reach hypersaturated state, from
And remove haze particle.
The present invention's removes the haze method amount of conserving water based on the oversaturated coring of steam, can reach 90% in enclosure space
Above removing PM2.5 removes haze efficiency, and open and semi-open environment clearance rate is up to 60% or more.

Specific implementation mode
Be described in detail with reference to the accompanying drawings and examples to of the invention further, following embodiment be it is descriptive,
Non-limiting, protection scope of the present invention cannot be limited with this.
This gives the elimination processes of the PM2.5 in natural haze.
In the present embodiment, as shown in Figure 1, air compressor 3 is followed by high pressure tank 4, high pressure tank 4 is followed by gas circuit pipe
Flow control valve 5 is simultaneously installed in road 6 on it, forms air supply system；Water pump 2 after water feed inlet 1 connects waterway tube after water pump 2
Road 7, and flow control valve 5 is installed on waterway pipe 7 and forms water system.It is atomizing mouth by water system and air supply system
Spray 8 provides the air and liquid medium of certain pressure, generates ultra micro air-water mist；The ultra micro air-water mist is grain size Spectral structure
D50 values are less than 15 microns and D90 values are less than 25 microns.
Ultra micro air-water mist is sprayed into semi-open atmospheric environment, the Temperature fall process and ultra micro of 4. -5 point in afternoon are passed through
The evaporation endothermic process of air-water mist so that form supersaturated vapor condensation by core of haze particle in atmospheric environment, passed through
Saturation increases the particle of 10 microns of formation or more, and gravitational settling achievees the effect that remove air PM2.5.As shown in Fig. 2, air is wet
Degree reaches supersaturation in 20 minutes, and at the same time, as shown in figure 3, PM2.5 indexes start to decline rapidly, final clearance rate reaches
65%。
In order to accelerate Temperature fall process, refrigerant can also be manually sprayed.
Atomizing mouth spray 8 in the present embodiment is vapor-liquid two phases nozzle, can also use effervescent atomizer, or close
Air supply system uses single-phase high voltage nozzle or ultrasonic atomizing nozzle.
