Specific embodiment
With reference to the accompanying drawings and examples, the present invention will be described in detail.
Embodiment one: a kind of gas superfine particulate matter capture processing unit, as shown in Figure 1, including discharge tower 1, being connected to
In discharge tower 1 and sprays the humidifier 2 of droplet, above humidifier 2 and makes the static characteristic machine of droplet induc- tion charging
Structure 3, above static characteristic mechanism 3 and be connected to discharge tower 1 in Shou Wu mechanism 4, wherein Shou Wu mechanism 4 with absorption mist
The polarity of drop, so that droplet be made to collect drippage.
As shown in Figure 1, Figure 3, humidifier 2 includes that humidifier 2 includes the support column 21 being connected in discharge tower 1, sets
In water tank 22, joining water box 22 and the multiple atomizers 23, joining water box 22 and mist that are connected to support column 21 outside discharge tower 1
Change the water inlet pipe 24 of spray head 23, the control circuit of the control injection intensity of atomizer 23, connection is wherein equipped with inside support column 21
The channel of water inlet pipe 24 and atomizer 23 offers venthole, venthole peripheral wall row along exhaust gas emission direction on support column 21
Multiple atomizers 23 are furnished with, so that exhaust gas be made to come into full contact with droplet.
As shown in Figure 1 and Figure 2, static characteristic mechanism 3 includes and the spaced anode ring 31 of atomizer 23 and anode
The cathode needle 32 of 31 coaxial spaced of ring setting, wherein cathode needle 32 is located at the one end of anode ring 31 far from atomizer 23, atomization
Spray head 23 is projected in anode ring 31.The cathode of anode ring 31 and power supply couples, and the anode of cathode needle 32 and power supply couples, thus
Form electric field.
Shou Wu mechanism 4 is the semicircular ring that two panels is connected to discharge 1 inner wall of tower and is coaxially disposed with discharge tower 1, two semicircles
Ring is connected with positive electricity, negative electricity respectively, to form electric field, the droplet with dust is captured, droplet is made to collect, drip.
The course of work: in exhaust gas discharge, exhaust gas passes through venthole, then contacts with droplet, droplet passes through charge attraction
Ultra-fine grain, heavy metal, thus by ultra-fine grain, heavy metal chelating；
After droplet adsorbs fine particle, Shou Wu mechanism 4 is collected droplet by electric field, but also having adsorbed the mist of dust
Drop can easily accumulate water droplet drippage, complete the capture to fine particle dust.
Embodiment two: a kind of gas superfine particulate matter captures processing unit as shown in figure 3, the difference from embodiment one exists
In: atomizer 23 is also connected with air inlet pipe 26, and air inlet pipe 26 is communicated with air pump 25, air accumulator, and atomizer 23 passes through high speed
Impact of the gas to water forms droplet.
The aperture very little of atomizer 23, easily blocks, and leads to atomizer 23 with impurity in water in order to prevent
It being blocked, filter is equipped in water inlet pipe 24, filter uses active carbon as filter material, the particulate matter in water is filtered,
Most of granule foreign is just eliminated into the water of atomizer 23 in this way, blocks atomizer so as to avoid impurity.
After droplet is formed, due to the effect of temperature, it will constantly evaporation in dedusting, makes droplet become smaller due to evaporation,
Dust-collecting efficiency is affected, it is necessary to pay attention to.In exhaust gas discharge, the temperature of temperature sensor detection exhaust gas, control are used
Circuit processed is coupled to temperature sensor, and issues control signal, and when temperature is higher, control water pump 27 increases hydraulic pressure, so that mist
Drop still can carry out capture processing to dust in the case where continuous evaporation.When temperature is lower, it is not required to too consider droplet gas
When change problem, in order to save water, control air pump 25 is pressurized so that droplet is broken up as smaller droplet, thus increase with
The contact area of exhaust gas reaches expected dust removing effects.
In order to further prevent droplet to evaporate, it is equipped with refrigerator at water tank 22, cools down to the water in water tank 22, makes
Water in water tank 22 is cold water.On the one hand cold water can prevent droplet from evaporating, on the other hand can also reduce exhaust gas in discharge tower 1
Temperature when touching outside air, a large amount of droplets will not be precipitated because of cooling and immediately so that exhaust gas is after the exit,
But as exhaust gas scatters, droplet is constantly precipitated again after cooling, so that the exhaust gas of discharge will not become white, reaches reduction
The problem of visual white pollutes.
Clear water droplet is lower than 5% to the average dustfall efficiency of fine dust, below to 2um fine if droplet is not charged
Dust is almost without trapping effect, this is because dust has certain hydrophobicity, the tension of water surface is larger, and dust cannot be introduced into
In water, therefore therefore in water tank 22 added with wetting agent, the physicochemical properties of aqueous solution is made to change, improves the profit to dust
Wet ability.
It, can be according to the metal captured in droplet meanwhile in order to increase droplet to the capturing ability of the dust such as heavy metal
Difference adds corresponding additive, to achieve the effect that further dedusting.
Embodiment three: a kind of gas superfine particulate matter capture processing unit, as shown in Figure 1, static characteristic mechanism 3 is carrying out
When installation, it is necessary first to open up through slot on the barrel of discharge tower 1, static characteristic mechanism 3 is then passed through through slot and is installed to mist
Change spray head 23 surface, finally again by through slot major part area fill seal, blend rubber circle by through slot remainder with it is quiet
Fill sealing in gap between electrical characteristics mechanism 3.
