However, this is not intended to limit the present invention to the specific form disclosed, it should be understood to include all changes, equivalents, and substitutes included in the spirit and scope of the present invention. Hereinafter, a microdroplet removal system for purifying exhaust gas including a contaminant and microdroplets according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a view for explaining the basic concept of the microdroplet removal system for purifying the exhaust gas containing the contaminant and the microdroplet which is an embodiment of the present invention. As shown in FIG. 1, the microdroplet removal system for purifying exhaust gas including contaminants and microdroplets, which is an embodiment of the present invention, includes a housing (1), a drop ejection apparatus (2), and a collision-votex remover ( 3) and droplet (re) supply device 4.

The housing 1 forms an overall appearance, and as shown, an inlet 11 for introducing a target gas including a plurality of fine droplets is formed on one side, and the droplet injection device 2 and the collision-vortex on the other side. A discharge port 13 through which the cleaning gas removed by the removal device 3 is discharged is formed, and an accommodation space 13 is formed between the inlet port 11 and the discharge port 12. The droplet injection device 2 and the collision-vortex removal device 3 are installed in this accommodation space 13.

The target gas will contain fine droplets (fine moisture or fine vapor) and contaminants of several micrometers in size. As the target gas, for example, it may be a flue gas emitted from a factory, a malodorous gas emitted from a composting facility. Since the droplet size of the target gas is very small, when only the cooling aggregation effect or the collision aggregation effect is used, there is a limit in the coarsening of the droplets, resulting in a reduction in the removal efficiency or a high cost for the removal. Accordingly, in the present invention, the size of the fine droplets is primarily increased through the droplet ejection apparatus 2 (humidity effect), and then the collision phenomenon between the particles is increased by the collision-vortex removing apparatus 3, By removing the condensed droplets, the removal effect on the microdroplets is maximized.

To this end, as shown in the drawing, a droplet injection device 2 is provided at the front end of the accommodation space 13 to coarse fine droplets and convert them into coarse droplets. By the droplet injection apparatus 2, the fine droplet of several micrometers size becomes large as the coarse droplet of several tens of micrometers, and the target gas A is changed into the coarse droplet target gas B. As shown in FIG. The droplet injector 2 injects liquid of the same quality as the fine droplet of the target gas. That is, when the fine droplets are water vapor, fine water particles are injected, and when the fine droplets are oil vapor, oil is injected. That is, the liquid stored in the droplet supply device 4 is sprayed to the front end of the receiving space 13 by the spray method through the droplet injection device 2, so that the fine droplets of the target gas flowing through the inlet 11 It will be a conversation.

Then, at the rear end of the receiving space 13 (collision-vortex removing apparatus 3 for removing the coarse droplets through the cooling effect, the collision effect, and the vortex effect is installed. The cleaning air C from which the coarse droplets have been removed is discharged through the discharge port 12. The collision-votex removing device 3 changes the air flow to form a vortex to generate a collision and vortex effect between the particles and the coarse liquid. Enlarging the enemy so that the coarse droplets fall by gravity, the collision-votex removal device 3 is provided with a heat exchange pipe to add a cooling effect to maximize the droplet removal effect. It will be described in more detail in FIG.

As such, the coarse droplet including the third liquid is supplied to the third droplet resupply device 4-3 which supplies the third liquid to the third droplet injection device 2-3 again.

As described above, since the liquid containing only one contaminant remover is injected from each droplet injection device, the waste liquid collected by the collision-votex removal device can be recycled again by simple purification and additional liquid input.

Meanwhile, an additional collision-vortex removing device 5 that permits a target gas pass through the three droplet ejection apparatuses 2-1 to 2-3 and three collision-vortex removing apparatuses 3-1 to 3-3.

The first to third droplet resupply devices (4-1 to 4-3) are collected.

FIG. 4 is a view for explaining a third embodiment of the microdroplet removal system for purifying exhaust gas including the pollutant and the microdroplet, which is an embodiment of the present invention, each composed of housings distinguished according to the pollutant gas. Unlike the first embodiment and the second embodiment, the third embodiment is composed of a plurality of housings in parallel, and each housing may be configured to have a single droplet ejection device, a collision vortex device, and a droplet supply device, respectively.

As shown in FIG. 4, the target gas including the first to third contaminants is introduced through the first inlet of the first housing 10 and is injected by the first droplet injection device 20. The first contaminating gas is removed by the liquid, the fine droplets are coarsened to convert into coarse droplets, and the coarse droplets are removed by the first collision-vortex removing device 30 by the inertia collision and vortex effects. This will be collected. The first droplet supply device 40 collects the coarse droplets collected by the first collision-votex removal device 30 and re-supply the first droplet injection device 20.

The first contaminant is removed through the first housing 10 so that the target gas including the second contaminated gas and the third contaminated gas and the plurality of fine droplets flows through the second inlet of the second housing 50. Second contaminant gas is removed by the second liquid sprayed by the second droplet spraying device 60, the fine droplets are coarsened to convert into coarse droplets, and the second collision-vortex removing device 70 ) To collect the coarse droplets while removing them by inertia collision and vortex effects. The second droplet supply apparatus 80 collects the coarse droplets collected by the second collision-vortex removing apparatus 70 and re-supply the second droplet ejection apparatus 60.

And the third contaminant gas is removed by the third liquid injected by the third droplet ejection apparatus 100, the fine droplets are coarsened to convert into coarse droplets, and the third collision-votex removing apparatus 110 is performed. ) To collect the coarse droplets while removing them by inertia collision and vortex effects. The third droplet supply apparatus 120 collects the coarse droplets collected by the third collision-vortex removing apparatus 110 and re-supply the third droplet ejection apparatus 100.

By constructing as described above, by removing each of the contaminants in the independent plurality of housings and recycling them, it is possible to minimize the waste water coming out of the exhaust gas purification.

Hereinafter, with reference to FIG. 5, the structure of the blade of the collision-votex removal apparatus will be described.

5 is a view for explaining a blade used in the collision-votex removal device of the fine droplet removal system for purifying the exhaust gas containing contaminants and fine droplets of an embodiment of the present invention. As shown in FIG. 5, the collision-vortex device 3 consists of a plurality of blades 31, each of which blades 31 may be integrally formed by a connecting rod (not shown).

The blade 31 may include a first blade 311, a second blade 312, a first blocking blade 313, a second blocking blade 314, a heat exchange pipe 315, and a refrigerant spray nozzle, as shown. And 316.

The blade 31 extends with a refractive angle from the first blade 311 and the first blade 311 which are formed to be inclined at a predetermined angle with respect to the flow of the target gas having the contaminant (wind of the target gas). It is formed at the connection point of the second blade 312, the first blade 311 and the second blade 312, it may be configured to include a heat exchange pipe 315 through which the refrigerant flows. The target gas collides with the blade by the refrigerant flowing in the heat exchange pipe 315 to cool and condense, and further, the first blade 311 and the second blade 312, the first blocking blade 313, and Vortex phenomena occur in the flow of gas by the second blocking blade 314, so that the droplets become large due to inertial collision, and thus fine droplets can be sufficiently removed.

In other words, since the first blade 311 and the second blade 312 are bent and formed, collision of the fine droplets increases due to inertial collision, thereby increasing the fine droplets. Furthermore, a pair of semicircular first blocking blades 313 is installed at the connection point of the first blade 311 and the second blade 312, and at one end of the second blade 312 is a semicircular second The blocking blade 314 is installed. Accordingly, the flow of the target gas is vortexed by the first blocking blade 313 and the second blocking blade 314, and thus the fine droplets are collected and collide with each other. The droplets collected by this phenomenon flow downward by gravity.

In addition, a heat exchange pipe 315 through which refrigerant flows is installed at a connection point, and the first and second blades 312 extend from the heat exchange pipe 315. The heat exchange pipe 315, the first and second blades 311 and 312, and the first and second blocking blades 314 may be made of a metal having high thermal conductivity. In particular, when using a metal material having high ductility, high thermal conductivity, and strong corrosion resistance, such as copper or aluminum, durability is excellent. In addition, the first and second blades 311 and 312, and the first blocking blade 313 and the second blocking blade 314 are cooled by a refrigerant, and thus the first and second blades 311 and 312 and The fine droplets colliding with the surfaces of the first blocking blade 313 and the second blocking blade 314 cause condensation by contact cooling, thereby coarsening. In addition, the heat exchange pipe 315 is installed in the target gas flow direction in the refrigerant injection nozzle 316. The refrigerant injection nozzle 316 serves to inject the refrigerant of the heat exchange pipe 315 to the target gas (a position where the vortex phenomenon occurs). Accordingly, the coolant injected from the coolant injection nozzle 316 lowers the ambient temperature and collides with the fine droplets, thereby maximizing the effect of removing the fine droplets.

According to one embodiment of the present invention having the above-described configuration, after coarse the fine droplets with the droplet injector first, by collecting and removing the coarse droplets with the blade causing the inertia collision and vortex (swirl) effect, the fine liquid It can be configured to maximize the removal efficiency of the enemy.

In addition, according to one embodiment of the present invention, since the refrigerant is injected into the target gas from the heat-exchange pipe to the collision-votex removal device, the cooling effect and coarsening of the target gas are simultaneously achieved to further increase the efficiency of removing the fine droplets. It can be configured to be.

In addition, according to one embodiment of the present invention, by independently reacting and neutralizing and removing contaminant gases contained in the target gas in the droplet ejection apparatus, wastewater generated while removing not only fine droplets but also contaminants may be recycled.
