The present invention relates to an insert-type odor reduction filter device, and more particularly, to an insert-type odor reduction filter device for removing odor and dust using an insert-type dry filter and a wet filter when air inside a pig farm is discharged to the outside. .

In general, pig farms breed pigs in buildings such as pig houses or pig farms. With the development of the livestock industry due to the increase in meat consumption due to the improvement of living standards, the breeding environment has been expanded and developed in various ways.

These pig farms increase the number of pigs by systematically managing breeding temperature, ventilation, excrement discharge, etc. in order to increase productivity, but they are recognized as disgusting facilities due to odor, causing many problems.

For example, in pig farms, odorous harmful gases mainly composed of ammonia and hydrogen sulfide due to pig excrement are severe, and various contaminants such as fine dust or pig hair caused by feed provided as feed or daily activities are generated in large quantities.

Therefore, due to odors or various contaminants generated from pig farms, the environment around the pig farms is destroyed or contaminated air is delivered to nearby housing facilities, causing unnecessary damage.

At the same time, pig farms are composed of closed spaces to protect pigs, so if the air inside the barn is not kept clean, the pigs die from various diseases, so the air in the barn must be periodically cleaned.

Accordingly, as shown in FIG. 1, in a conventional pig farming household, a ventilation device 20 having a fan duct 21 and a communication pipe 22 is installed in a pig farm 10 to only discharge odor to the outside, reducing odor effect is not provided.

Hereinafter, an insert-type malodor reduction filter device according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the insert-type odor reduction filter device 100 according to the present invention is installed in a pig farm 10, such as a pig farm where a large number of pigs are raised in groups, and the air in the pig farm 10 is exhausted to the outdoors (outdoor). Remove odor-causing substances or dust.

In comparison, in the prior art, it is limited to smoothly discharging the air inside the pig farm 10 using an exhaust duct (elbow pipe, 21) and a ventilation fan installed inside the pig farm 10, causing many civil complaints. do.

In addition, in order to solve the above problems, building a ventilation system with a separate filter function added to the conventional pig farm 10 can reduce civil complaints and reduce environmental pollution, but the cost increases as the device becomes very large. will make

On the other hand, the present invention removes both odor and dust by connecting and installing an insert-type dry filter and wet filter to the already installed ventilation fan system 20. Therefore, while minimizing the increase in size or cost of the purification device, it is possible to remove odors generated from the pig farm 10 and reduce civil complaints from the surroundings.

To this end, the insert-type odor reduction filter device 100 of the present invention is connected to the outside of the pig farm 10 to purify the air exhausted from the inside of the pig farm 10, including a filter case 110 and a dry filter 120. , a wet filter 130 and a control module 140.

FIG. 3 showing this shows a state in which the insert-type odor reduction filter device 100 of the present invention is modularly assembled, and FIG. 4 shows a ventilation system ( 20: 21, 22) shows the mounted state.

At this time, as shown in FIGS. 5 and 6, the filter case 110 is a frame in which a dry filter 120 and a wet filter 130, which will be described later, are installed, and is a ventilation fan for exhausting air inside the pig farm 10 to the outside. It is connected to the exhaust side and has an air flow passage.

In an embodiment, the dry filter 120 is installed inside the filter case 110, and the wet filter 130 is installed in the exhaust direction, that is, on the outer upper surface of the filter case 110. At this time, the air flow passage is formed through so that indoor air discharged from the pig farm 10 is discharged after passing through each filter.

Specifically, the filter case 110 includes a lower case 111, an upper case 112, and a side cover 113, and each of the lower case 111 and the upper case 112 has a corner portion bent to form a side surface. Equipped with, the side cover 113 is detachably assembled to the open portion of them to block it.

At this time, the lower case 111 is installed to cover the exhaust side passage of the ventilation fan. That is, the lower case 111 is assembled to be connected to the exhaust side of the previously installed ventilation fan, and has an inlet hole 111a through which air discharged from the pig farm 10 flows.

The ventilation fan may not be visible from the outside when installed inside the ventilation duct (elbow pipe) fixedly installed on the outer wall of the pig farm 10. Of course, other than that, when assembled on the inner wall surface of the pig farm 10 or on the side of the ventilation duct, it can be seen from the outside as well.

In addition, since the lower case 111 has side edges bent upward, the dry filter 120 is seated and assembled in the inner space thereof.

In particular, the lower surface of the lower case 111 may be made in an oblique shape to have an inclined surface (upward slope, S-b) rather than a flat surface so that air discharged from the pig farm is well discharged when air is exhausted by a ventilation fan.

The upper case 112 is installed to cover the lower case 111 above the lower case 111 . The upper case 112 has a corner bent downward to completely cover the dry filter 120, and an exhaust outlet 112a is formed therethrough to discharge air passing through the dry filter 120.

At this time, the upper surface of the upper case 112 may be made in an oblique shape to have an inclined surface (upward slope, S-t) so that the air emitted from the pig farm is well discharged when air is exhausted by the ventilation fan.

If the upper surface of the upper case 112 has a flat surface, there is a possibility that the air being blown by the ventilation fan blows here and the wind returns to the opposite side, in which case a load is applied to the ventilation fan, so providing an inclined surface desirable.

Indoor air of the pig farm 10 exhausted through the exhaust outlet 112a may be exhausted upward through the communication pipe 22 inserted into the upper end of the upper case 112 .

The side cover 113 constitutes a side portion of the filter case 110 and is detachably assembled to manage the dry filter 120 .

For example, the side cover 113 is detachably assembled on either side of the open side of the upper case 112 and the lower case 111 with assembly bolts or the like. Therefore, cleaning or replacement of the dry filter 120 is possible.

However, it is preferable to add a packing (P1) to the interface where the lower case 111 and the upper case 112 come into contact. The packing (P1) is interposed between the cases 111 and 112 to absorb vibration and Prevent foreign matter such as rainwater or dust from entering.

For the same reason, packing (P2) may be added between the side cover 113, and each packing (P1, P2) is provided in a 'c' or 'c' shape according to the shape of the junction.

On the other hand, as described above, the dry filter 120 is installed inside the filter case 110 to purify the air inside the pig farm 10 being discharged to the outside, and primarily removes dust and the like.

The dry filter 120 means a dry type filter, unlike the wet filter 130 to be described later, which uses a cleaning solution. As an example, a bio filter (bio -filter) can be applied.

The biofilter has the advantage of being able to adsorb and remove dust, as well as providing an effect of removing odor while immobilizing microorganisms when provided with a carrier.

The wet filter 130 is installed at the rear end of the dry filter 120 to secondarily purify the air of the pig farm 10 that has been primarily purified by the dry filter 120.

To this end, the wet filter 130 purifies the air inside the pig farm 10 with the sprayed liquid. In particular, it provides a great effect in reducing ammonia contained in the air.

In an embodiment, the wet filter 130 includes a clean duct 131 , a spray nozzle 132 and a cleaning liquid supplier 133 .

Here, the clean duct 131 is connected to the discharge side of the filter case 110 and provides a passage through which air is discharged. As shown, the clean duct 131 may be an exhaust pipe extending from the discharge hole of the upper case 112 .

The spray nozzle 132 sprays the cleaning liquid onto the air discharge path provided by the clean duct 131, and preferably, a mist spraying device for spraying the cleaning liquid in a mist type may be applied.

In addition, as long as the spray nozzle 132 faces the air discharge path of the clean duct 131, horizontal or downward spray is possible, and if it can collect other ammonia or the like, it can be sprayed upward of the clean duct 131 like a fountain. can also be sprayed.

As shown in an example, a support frame crossing the hollow of the clean duct 131 is provided for installation of the spray nozzle 132, the spray nozzle 132 is assembled at the center of the support frame in the longitudinal direction, and the supply Hose can be connected.

The cleaning liquid supplier 133 supplies a cleaning liquid for collecting and neutralizing ammonia in the air to the spray nozzle 132 . As an example, a mixture of water and a decomposition liquid may be applied as the cleaning liquid. A variety of well-known decomposition liquids, such as amine-based or hydrogen-containing as well as microorganisms, may be applied.

As shown in FIG. 2, the washing liquid supplier 133 includes an air compressor 133a and an air supply pipe connected to the air compressor 133a on one side of the pig farm 10 so that the washing liquid can be sprayed in a mist type to transfer and eject the washing liquid with high-pressure air. allow it to be done

At this time, it is operated by a pump and has a storage tank 133b containing the cleaning liquid so that the mixed cleaning liquid can be sprayed by high-pressure air, and the supply of high-pressure air and cleaning liquid is controlled by an electronic controller (controller 142).

However, when the washing liquid supplier 133 is installed outside the pig farm 10, a hot water circulation boiler 150 may be further included to prevent freezing and bursting when the temperature is low, such as in winter. The hot water circulation boiler 150 is connected to a plurality of insertion type odor reduction filter devices 100 provided in the pig farm 10 through circulation pipes to circulate a heat source for freezing prevention.

The control module 140 is for controlling the insert type malodor reduction filter device 100 of the present invention, and particularly controls the operation of the wet filter 130. Specifically, the operation of the ventilation fan is detected, and the wet filter 130 is controlled to operate only when the ventilation fan is in operation.

Therefore, the present invention operates the wet filter 130 only when the air inside the pig farm 10 is being discharged to the outside as the ventilation fan operates, thereby preventing waste of washing liquid and power energy to provide an eco-friendly environment. make it possible

To this end, the control module 140 includes a blowing sensor 141 and an electronic controller 142 .

The blowing sensor 141 detects the operation of the ventilation fan, and preferably a vibration sensor is applied. The vibration sensor is attached to the filter case 110 to detect vibration caused by the operation of the ventilation fan.

As shown in FIG. 3 , the vibration sensor applied to sense airflow may be attached to the filter case 110 as an example. More specifically, it may be installed in close contact with the upper case 112, which is a component of the filter case 110.

Since the filter case 110 including the upper case 112 is connected to the exhaust duct 21 (elbow pipe) through which air inside the pig farm 10 is discharged to the outside by the ventilation fan, vibration generated during operation of the ventilation fan It is transmitted to the filter case 110 through the exhaust duct 21, and the vibration sensor accurately detects it.

Therefore, the electronic controller 142 determines that it is necessary to purify the air in the pig farm 10 when it is read by the blowing detection sensor 141 that the ventilation fan is operating, and operates the washer fluid supplier 133.

However, as the blowing detection sensor 141, sensing the air flow phenomenon itself may be additionally applied. For example, a pinwheel-type sensor may be installed in the hollow of the clean duct 131 to detect rotation of the air in the pig farm 10 when it is discharged, and a vibration sensor may be separately added. However, since these sensors are affected by the external environment (external wind, etc.) and the accuracy of the vibration sensor is higher, it is preferable to use them together with the vibration sensor.

As described above, the present invention removes odor and dust by connecting and installing the dry filter 120 and the wet filter 130 at the rear. That is, the dry filter 120, such as a biofilter, mainly removes dust and the like, and the wet filter 130, which sprays a cleaning liquid, reduces dust as well as odor-generating substances such as ammonia.

In addition, since the present invention is inserted into an already installed ventilation fan system, it is possible to remove odors generated from the pig farm 10 and reduce complaints from the surroundings while minimizing the size or cost increase of the purification device.

In the above, specific embodiments of the present invention have been described in detail. However, the spirit and scope of the present invention is not limited to these specific embodiments, but those skilled in the art can make various modifications and variations without changing the gist of the present invention. You will understand when you grow up.

Therefore, since the embodiments described above are provided to completely inform those skilled in the art of the scope of the invention to which the present invention pertains, it should be understood that it is illustrative and not limiting in all respects, The invention is only defined by the scope of the claims.
