Description

[0001] INTEGRATED IMPACTOR AND CYCLONE DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for air cleaning and particle collection, and more particularly to an impactor and a cyclone apparatus in which a series type impactor and a wet axial cyclone are integrated.

In general, Impactor and Cyclone are devices that capture particles.

Impactor is a particle that is large in size when the particles entering through the inlet move along the flow of the fluid. The particles with large inertia force can not follow the flow of the fluid and collide with the trapping surface. It is a method using the phenomenon of escaping toward the exit along the flow of the flow.

Cyclone is a particle that is large in size when the particles entering through the inlet are rotating along a vortex finder or vane. Particles with large inertia force have relatively large centrifugal forces, The particles with small inertia force are collected by the collision, and the particles are discharged through the flow along the flow.

Therefore, Impactor and Cyclone are used effectively for air purification or particle collection in power plants, factories, incinerators, various measurement equipments and so on.

Domestic registered patent 10-1273421 (June 04, 2013)

Both Impactor and Cyclone are efficient for air cleaning or particle capture, but are individually developed and used.

For example, an impactor is largely divided into a real impactor in which a collision actually occurs and a virtual impactor in which a virtual collision occurs. The inert impactor impacts the particles on the trapping surface and collects the particles. It is easier to make the device more compact and higher flow rate than the virtual impactor, but it is easy to produce. However, after the particles hit the trapping surface, A phenomenon of influx occurs. Since the virtual impactor has no actual collision, there is no phenomenon that the particles are repelled by the trapping surface and reintroduced into the flow, but it is not suitable for the high flow rate as compared with the inertial impact type impactor, and the apparatus is complicated.

 Cyclone can also be divided into a general cyclone type with a general vortex finder in which the flow is radially accelerated and an axial cyclone with an axially accelerated vane. Conventional cyclones are well-designed and easy to design, but they are disadvantageous for miniaturization of the device because the direction of the flow must be different from the device attached to the shear end. In the case of the axial cyclone, it is difficult to find the existing research formulas, which is disadvantageous to the design, but it is advantageous for the miniaturization because the direction of the flow is the same as the device attached to the shear.

In view of the above, the present invention can reduce the size of the apparatus by combining an inertial impact type impactor having a ring-shaped nozzle advantageous for miniaturization and an axial cyclone, and a water injection device is added to the cyclone portion, In the case of an inertial impact type impactor with a ring-shaped nozzle, the flow deflection section is smaller than that of the conventional impactor. And to provide an integrated impactor and a cyclone device that is more advantageous for miniaturization of the apparatus.

Another object of the present invention is to provide an integrated impactor and cyclone device in which a series-type impactor is attached at the front end and a solution containing particles of a designated size can be easily manufactured by connecting the wet axial cyclones in series have.

It is a further object of the present invention to provide an impactor and a cyclone device in which an impactor used as a pretreatment separator at the front end is manufactured as an integrated unit with an axial cyclone at the rear end or as a separate unit and can be fastened by various methods such as a flange or a sunny It is in the cage.

Water injected into the cyclone is injected into an ultrasonic or pneumatic injection device.

The impactor collecting surface of the impactor further includes a coating layer formed of a porous plastic material impregnated with an oil layer or oil by grease application to a collision site where the particles are collected.

The connecting portion between the impactor and the cyclone is fastened by a flange.

The impactor adjusts the distance between the impactor wall and the particle impact surface, and the length of the particle impact surface. The size of the collected particles is controlled by the distance between the inlet and the vane and the pitch of the vane.

The impactor collecting surface of the impactor and the vane of the cyclone are integrally formed on one shaft.

A solution collecting cylinder is further formed at the solution outlet end of the cyclone housing constituting the cyclone, and the solution collecting cylinder portion is elongated so as to narrow toward the outlet of the solution.

The anti-reverse flow cylindrical bar is inserted into the vane axis constituting the cyclone and the impactor shaft constituting the impactor, and a plurality of small pillars are radially formed in the anti-reverse flow cylindrical rod for fixation.

The present invention can realize a synergistic performance between an impactor and a cyclone by producing a wet axial cyclone including a series type impactor. In particular, a solution containing a particle of a specific size or larger, It is effective to design a continuous system for manufacturing the above-mentioned apparatus.

In addition, the present invention is advantageous in downsizing the apparatus by attaching the cylindrical impactor and the axial cyclone directly to the rear end of the impactor, and in particular, there is no need for additional fitting of the apparatus, which is advantageous in terms of pressure loss.

In addition, the present invention can be used as an apparatus for treating various contaminants in the air using the feature of cyclones capable of trapping particles, and in particular, it is possible to design a mechanical design capable of controlling the inflow of particles smaller than a desired size at the downstream of the cyclone, Prevention facilities and defense CBRs.

The vacuum pump 50 is a vacuum pump.

The impactor 10 has a cylindrical shape and functions as a preprocessor for filtering particles larger than a specific size.

To this end, the impactor 10 comprises an impactor housing 11, an outlet connector 13, and an impactor shaft 15.

In particular, the impactor housing 11 is accelerated in the radial direction so that the impactor 11 is wound in a ring-shaped nozzle 11 having a horizontal direction of impact, and the impactor housing 11 is formed into a cylindrical shape, so that the circular periphery of the impactor housing 11 forms an entrance. and a ring-shaped nozzle.

The outlet connector 13 is formed in a cylindrical shape having a diameter smaller than the diameter of the impactor housing 11 at the center of the impactor housing 11. Therefore, the impactor 10 according to the present embodiment has a cross-sectional shape of "T".

The impactor shaft 15 penetrates the impactor housing 11 and has its lower end positioned by the outlet connector 13 and its upper end protruding out of the impactor housing 11. Therefore, in the impactor 10 according to the present embodiment, the blower 30 is engaged with the impactor shaft 15 at the upper portion thereof.

The impactor shaft 15 is integrally formed with the vane shaft 25 of the cyclone 20 so that the impactor shaft 15 can be made integral with the vane shaft 25.

The cyclone 20 is of a wet axial type and consists of a cyclone housing 21, a vane axis 25 and a vane 27.

The cyclone housing 21 is formed in a cylindrical shape having the same diameter as the outlet connector 13 of the impactor 10. In addition, an injection tube 23-1 for injecting water into the inside of the cyclone housing 21, a solution containing particles having a specified size in the cyclone housing 21, And a discharge pipe 23-2 for discharging the gas to the outside.

In particular, the injection tube 23-1 is not limited to a side or a bottom of the cyclone housing 21 or a specific position.

The vane shaft 25 is connected to the impactor shaft 15 of the impactor 10 and rotated together with the impactor shaft 15. The vane shaft 25 is integrally formed with the impactor shaft 15 of the impactor 10 so that the vane shaft 25 can be made integral with the impactor shaft 15.

The vane 27 is composed of first, second, and third wings 27-1, 27-2, 27-3 continuous in the axial direction of the vane shaft 25. Actually, the number of wings 27-1, 27-2, 27-3 can be changed according to the performance of the concentrated solution production including the particles of the designated size.

Particularly, in this embodiment, the impactor 10 and the cyclone 20 are connected to each other by using the picker 100. Specifically, the picker 100 connects and fixes the outlet connector 13 of the impactor 10 and the cyclone housing 21 of the cyclone 20 to each other. A flange fastening method may be applied to the filler 100 for this purpose.

The blower 30 operates the impactor 10 and the cyclone 20 by rotating the impactor shaft 15 and the vane shaft 25 so that the inside of the impactor 10 and the cyclone 20 are filled with contaminants Together, a constant flow of air from the outside is generated.

The water injection system 40 supplies water to the inside of the cyclone housing 21 by injecting water into the injection tube 23-1 formed in the cyclone housing 21 of the cyclone 20. [

In the present embodiment, the water supplied into the cyclone housing 21 may be applied by a droplet discharge method using the ultrasonic injector 40-1 or the pneumatic injector 40-2. Therefore, the installation position of the water injection system 40 may be mounted using a front end or a bottom end of the cyclone 20, or a plurality of the water injection system 40 may be installed at a plurality of positions to improve water injection performance. Particularly, the ultrasonic wave injector 40-1 can apply ultrasonic vibration to the water to be injected as seen through the action of ultrasonic waves.

The vacuum pump 50 is connected to the discharge pipe 23-2 formed in the cyclone housing 21 of the cyclone 20 so that the cyclone 20 is filled with the cyclone 20, And then discharges the solution containing the particles larger than the specific size filtered out through the outlet.

Figure 2, on the other hand, shows the design major parameters for the impactor 10.

As shown, the impactor 10 applies the distance S between the wall and the collecting surface and the length M of the collecting surface as design parameters, so that the size of the collected particles is equal to the distance S between the wall and the collecting surface, And the length M of the collecting surface. In addition, the impactor 10 designs the impact direction in a direction perpendicular to gravity. Here, the length M of the collecting surface means the length of the collecting surface. In addition, the collecting particles mean contaminants in the air, and the particles mentioned below mean contaminants in the air.

In particular, the impactor 10 is made cylindrical so that the axial type cyclone 20 can be directly connected as if it were one piece of equipment. To this end, the tube outer diameter of the device attached in a hydrodynamic topology via the Stokes' equation is substituted and the dimension of the impactor 10 satisfying this equation is derived.

In addition, in the present embodiment, the impactor 10 can prevent the particles colliding with the impactor trapping surface 15-1 from being thrown out by further forming the coating layer 17 on the impactor trapping surface 15-1. For this purpose, the coating layer 17 may be formed of a porous plastic material coated with oil or grease, such as grease.

Figure 3, on the other hand, shows design design parameters for the cyclone 20.

Therefore, the cyclone 20 can be determined from the size of the trappable particles from the change of the distance L between the inlet and the vane and the pitch P of the vane.

For example, when the size of the collected particles of the cyclone 20 is reduced, the first, second, and third wings 27-1, 27-2, 27-3 are rotated The flow rate is increased while increasing the number and the pitch P of the first, second, and third wings 27-1, 27-2, 27-3 is reduced to increase the flow rate.

Meanwhile, FIG. 4 shows the operation of the integrated impactor and cyclone device according to the present embodiment.

As shown in the figure, when the integrated impactor and the cyclone device are operated, a constant flow rate of the air introduced from the outside together with contaminants in the air is generated by the blower 30 in the inner space of the impactor 10 and the cyclone 20 And a certain amount of water is supplied by the water injection system 40.

In this process, in the impactor 10 through which the fully developed flow is introduced through the inflow device, the flow passes through the impactor trapping surface 15-1, Contaminant particles are collected. Particularly, the application layer 15-1 formed on the impactor trapping surface 15-1 prevents particles from bouncing out due to the action of a porous plastic material impregnated with oil or oil such as grease. The particles referred to below mean pollutant particles.

Therefore, the impactor 10 acts as a preprocessor for filtering out particles larger than a specific size.

Then, in the cyclone 20, the action of the wet axial cyclone is effected to produce a solution containing particles of a designated size. The vacuum pump 50 connected to the discharge pipe 23-2 formed at the end of the cyclone 20 operates to generate the solution having the specified size of particles using the vane 27, The solution containing the particles is extracted.

Meanwhile, FIG. 5 shows a modified example in which cyclone solution collection performance improvement and cyclone backflow prevention are further added to the integrated impactor and cyclone apparatus according to the present invention.

In addition, the anti-reverse flow cylindrical bar 200 is inserted into the vane shaft 25 constituting the cyclone 20 and the impactor shaft 15 constituting the impactor 10. Particularly, the backflow preventing cylindrical bar 200 is further provided with small columns arranged radially for fixing. Therefore, the inner space of the vane axis 25 and the impactor shaft 15 is formed by the vortex axis 25 and the backflow preventing cylindrical bar 200 fixed along the small column radially provided on the impactor shaft 15, The donut-shaped portion of the euros can help prevent backflow.

As described above, the integrated impactor and the cyclone apparatus according to the present embodiment use the ring-shaped nozzle impactor 10, which is accelerated in the radial direction so that the impact direction is in the horizontal direction, as the pretreatment separator, And a cyclone 20 for producing a solution containing particles having a specified particle size through a wet axial cyclone.
