In detail, pollutants pass through a filter that performs two-sided discharge and reduce organic matter to reduce installation area and installation cost, and purify air to prevent secondary pollution such as microorganism air diffusion and sewage generation. Relates to a device.

In order to prevent environmental pollution, in the composting treatment facility or food waste treatment facility where various compost fertilizers are stored or farms and livestock raising a large number of livestock, a purification device is used to filter odors generated inside the facility and spread to the atmosphere. Is installing.

Such a purification device is one of devices for performing deodorization, and may illustrate a filtration system for decomposing odor molecules by a filter obtained by culturing microorganisms in mud, sawdust and the like.

An alternative purification device may be provided for supplying a large amount of oxygen or performing deodorization by chemicals such as ozone. In particular, the equipment by the chemical is configured to install a dedicated equipment for generating a large amount of oxygen or chemicals.

In the conventional purification device as described above, in the case of the filtration system by microorganisms, the area for installing the facility is large and high installation cost is required. In particular, the microorganism performing the deodorization is suspended in the air, or contained in sewage is a problem that becomes a secondary source of pollution.

Referring to the drawings, the air purifying apparatus according to the present invention comprises a suction duct 10, a collecting filter 20, a two-face discharge filter 30, a fan 40. In the figure, the space in which the pollutants are generated is an example of the barn 1, and is shown by cutting a part of the roof to show a state in which the suction duct 10 is installed therein. In addition, the pollutant is described in the meaning including a variety of organic substances that cause odors and odors that are suspended in the barn (1).

The suction duct 10 is installed in the space where the pollutant is generated and is configured to form a passage through which the pollutant is sucked. At this time, one side of the suction duct 10 is exposed to the outside is coupled to the collection filter 20.

In particular, the suction duct 10 is configured to be installed above the inside of the barn (1) is configured to improve the collection efficiency of contaminants by branching a large number of branch pipes 12 in the main pipe body (11).

The collecting filter 20 is installed at an end exposed to the outside of the suction duct 10. Such a collecting filter 20 is configured to collect solid particles of contaminants, and typically, a diffusion electrostatic precipitator (DESP) or a dehumidifying filter is applied.

For reference, the diffusion type electrostatic precipitator is a device for collecting and collecting the fine particles of a solid having a relatively large particle size (in fact, fine particles contained in indoor air). In addition, the dehumidification filter is configured to evaporate the moisture of the pollutant conveyed by the suction duct 10 to collect the solid particles by the trapping material.
In particular, FIG. 5 shows one of the electrostatic precipitators as described above, and the electrostatic precipitator shown in the drawing has been developed so as to obtain economical and stable efficiency by integrating the electrostatic precipitator by installing a multicyclone as a pretreatment device at its front end. In addition, after the dust collector is installed (not shown) in the duct of the rear end of the dust collector, the dust is collected again and the particles are re-scattered to improve the overall dust collection efficiency. Such an electrostatic precipitator omits the above description in a known configuration.
In addition, the most basic configuration of the dehumidification filter can be configured by combining the metal mesh on both sides of the zeolite in the form of a flat plate, as shown in the drawing, it is common to perform the collection function by stacking one or more of such a configuration, such a The structure of the dehumidification filter is already well-known, and the above description is abbreviate | omitted.

The two-surface discharge filter 30 is coupled to one side of the collection filter 20. The two-phase discharge filter 30 is configured to decompose the organic material in the gas by the energy generated by colliding with the electrons generated by the plasma energy. Typically, a DBD (Dielectric Barrier Discharge) system is applied to perform a two-plane discharge.

The DBD system utilizes plasma energy to generate strong energy by colliding with molecules of organic materials to generate energy, which is then decomposed and converted into inert materials.

The configuration of the two-phase discharge filter 30 is the same as in FIGS. 2 is a front view illustrating the two-phase discharge filter of FIG. 1, FIG. 3 is an enlarged view of a portion A of FIG. 2, and FIG. 4 is a perspective view of the dielectric substrate of the two-plane discharge filter of FIG. 1.

Referring to the drawings, the two-plane discharge filter 30 is composed of a frame 31, a dielectric substrate 32, a spacer 33.

The dielectric substrate 32 is disposed in a plurality of columns and rows in a space formed inside the frame 31. At this time, the dielectric substrate 32 is coupled to a plurality of at regular intervals so as not to interfere with each other electrically. Thus, the spacer 33 is a member of the non-conductor coupled between each dielectric substrate 32.

In particular, the dielectric substrate 32 is disposed between the copper thin plate electrodes 32a and the copper thin plate electrodes 32a at intervals, and is discharged between the copper thin plate electrodes 32a to generate electrons. It consists of the aluminum electrode 32b. The two electrodes 32a and 32b have an optimal configuration for generating electrons for decomposing organic materials. The aluminum oxide electrode 32b is formed to have a thickness of approximately 0.3 mm and the copper thin plate electrode 32a has a thickness of approximately 0.03 mm. It is preferable to. In addition, the positive electrodes 32a and 32b are naturally connected to an external plasma generator and the like.

The fan 40 is configured to be combined with the two-phase discharge filter 30. Such a fan 40 is filtered through the exhaust pipe 50 of FIG. 1 to discharge the air from which the pollutants are removed.

That is, the fan 40 may be referred to as a power for sucking contaminants through the suction duct 10 and performing an exhaust process through the exhaust pipe 50. Accordingly, the collection filter 20 and the two-side discharge filter Naturally, 30 is configured to allow contaminants to pass through.

In the air purifier configured as described above, the contaminants generated in the livestock house 1 proceed to the outside through the suction duct 10 by the suction force of the fan 40. At this time, the contaminant is first filtered through the collection filter 20, such as an electrostatic precipitator or dehumidification filter coupled to the suction duct 10 is collected.
