Description

[0001] DROPLET SEPARATION TYPE ODOR REDUCING APPARATUS [0002]

The present invention relates to a malodor reduction apparatus, and more particularly, to a malodor reduction apparatus capable of reducing malodor by separating malodorous components through liquid separation by inertia after injecting a chemical liquid into air containing malodorous components.

Recently, various environmental improvement projects have been carried out in order to build a pleasant and hygienic living environment. In the treatment of food waste, automatic collection facilities for municipal wastes by vacuum suction system are being constructed centering on large-scale joint residential complexes. As disclosed in Korean Patent No. 10-1408736, the municipal waste collection facility includes an input facility, a pipeline facility, and a collection facility including a conveyance line for automatically collecting and treating municipal waste through a conveyance line buried underground. Such municipal waste automatic collecting facility connects garbage input port installed inside or outside of the building to a conveyance line buried underground, thereby collecting garbage automatically from the collection facility. In other words, the municipal waste collection facility uses the air pressure generated by the suction blower to transfer the food or general waste generated in the housing complex and the commercial complex to the collection point along the conveying line. At this time, the collecting facility includes a centrifugal separator for separating collected municipal waste, a suction blower installed in the collecting place to generate the necessary air pressure in the conveying line, a dust collecting facility, and a cooling facility. On the other hand, in such an automatic collecting facility, odor is generated from food or other garbage. To this end, a deodorizing device is provided at the end of the collecting box to remove odor components in the air and then discharged to the outside. As such deodorization equipment, a scrubbing type scrubber is mainly used. However, since the performance of such a conventional deodorization equipment is poor, odor components are discharged into the atmosphere as it is, and thus many complaints are occurring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure and operation of a droplet separation and odor reduction apparatus according to the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

Fig. 1 shows an overall configuration diagram of a droplet separation bad odor reducing apparatus according to the present invention. As shown in FIG. 1, the apparatus for reducing odor of droplets according to the present invention includes a chemical liquid injecting unit 10, an airflow accelerating unit 20, and a liquid separating unit 30.

The chemical solution injecting section (10) is a part for spraying a chemical solution adsorbing and binding to the malodor component in a fine droplet form in the air containing the malodor component. As shown in FIG. 1, the chemical liquid injecting unit 10 is configured as a hollow body, and the injection nozzle 14 is provided therein. The injection nozzle 14 is connected to a tank in which a chemical solution for adsorbing odorous components is stored in advance, and injects the chemical solution in real time or periodically into the chemical solution injector 10 enclosure. The injected chemical liquid is sprayed in the form of fine droplets (water droplets) so that it can be easily combined with the odor component contained in the air.

An air inlet (11) is provided at one side of the chemical solution injecting part (10), and air containing odorous substances flows into the inside. The air inlet 11 is connected to, for example, the end of a conveying pipe of the automatic garbage collecting system so that odor air generated in the conveying duct can be introduced and transferred. At this time, the air can be introduced into the chemical liquid injecting portion 10 by the suction force of a suction blower (not shown) installed in the automatic garbage collection system. As shown in FIG. 1, the chemical solution injector 10 is provided with a partition 12 having one side opened to form a flow path for air to be transferred in one direction. It is preferable that a plurality of separate injection nozzles 14 are formed for each of the compartments divided by the partition 12.

As described above, the fine liquid droplets of the chemical liquid sprayed from the injection nozzle 14 inside the liquid injecting portion 10 are continuously conveyed together with air in a state of being adsorbed to the odor component contained in the air. Meanwhile, a drain pipe 18 may be additionally provided at a lower side of the chemical solution injecting unit 10 for recovering and discharging the chemical solution falling downward without being adsorbed by the malodorous component.

The airflow accelerating portion 20 is a portion for primarily increasing the flow rate of air containing a combined substance of the chemical liquid microdroplet and the malodor component (hereinafter referred to as "transport air"). In order to remove the malodorous component from the air, it is necessary to remove the malodorous component adsorbed and bonded to the chemical liquid droplet from the air. In the present invention, they are separated from each other due to the difference in inertial force. That is, when the transport air is accelerated, the mass of the combined substance of the chemical liquid microdroplet and the odor component is different from the mass of the air, so that when the velocity is decelerated later, the mutual separation becomes possible due to the difference of the inertia force. The separation action due to the difference in inertial force is performed in the liquid-liquid separator 30, which will be described later. For this purpose, the air-current accelerating unit 20 primarily performs air acceleration in advance.

1, the airflow accelerating section 20 is constituted by a hollow housing and is connected to one side, preferably an upper side, of the chemical solution injecting section 10 by a connection pipe 16, Air is introduced. As shown in the figure, a guide vane 22 is provided in the airflow accelerating unit 20. The guide vane 22 is for accelerating the conveying air. The guide vane 22 is disposed so as to cross the flow path of the airflow accelerating portion 20, and has a plurality of air passages having a relatively small diameter. The guide vane 22 may be formed of an aggregate of a plurality of tubes or may be formed in a block shape in which a plurality of honeycomb-shaped openings are formed. And, as shown in the figure, the air passage may be formed in a zigzag shape to increase the resistance of the air. As described above, the flow velocity of the transferred air increases while passing through a plurality of air passages having a relatively small diameter.

The liquid-liquid separator 30 receives the transported air having the increased flow velocity in the air-flow accelerator 20, accelerates the air again, and separates and collects the combined liquid of chemical liquid droplets and odorous components. . The liquid-liquid separator 30 is also configured as a hollow body, and a lower portion thereof is connected to the airflow accelerating portion 20 so that the first-accelerating conveyed air is introduced.

The liquid-liquid separating unit 30 includes an air-flow distribution port 31 for separating fine liquid droplets of the lyophilus and a compound of the odorous substance from the air due to the inertial force difference. 1, the air flow branching port 31 has a large-diameter pipe 31a having one end connected to the airflow accelerating portion 20 and the other end extending to the inside of the liquid-jet separating portion 30, And a plurality of small-diameter pipes 31b connected to the pipe 31a and having a relatively smaller diameter than the large pipe 31a.

In Fig. 3, a preferred temporal example of such an airflow distribution port 31 is shown. As shown in the figure, the large-diameter pipe 31a is horizontally extended and bent downward by about 120 °, and a plurality of small-diameter pipes 31b are disposed therein. The end of the small-diameter pipe 31b is about 50 mm And is disposed in a state exposed from the end of the large-diameter pipe 31a. The diameter of the large-diameter tube 31a is generally about 500.phi., And the diameter of the small diameter tube 31b is generally about 20 .phi., Preferably about 20 to about 30 diameters. A mesh 31c is formed at the distal end opening of the small-diameter tube 31b. On the other hand, a certain level of water is stored in the lower portion of the liquid-liquid separating unit 30, and the end of the air-flow branching port 31 is bent downwardly while being submerged in the water stored in the lower portion of the liquid- .

The structure of the airflow branching port 31 is for separating the combined chemical liquid microdroplet and the malodorous component from the air easily due to the inertial force difference as the transport air is accelerated and decelerated again. The conveying air that has passed through the large-diameter pipe 31a having a relatively large diameter passes through a number of small-diameter pipes 31b having a relatively small diameter while the flow velocity increases, and the conveyance air discharged from the small- The air is suddenly decelerated as it is discharged into the water stored in the lower part of the inside of the liquid- As the accelerated transport air is rapidly decelerated, the combined substance of the chemical liquid microdroplet and the odor component contained in the transported air is separated by the inertial force difference with the air. Accordingly, the combined hydrophilic and hydrophilic liquid droplets and the odorous components are collected in the water, and the remaining air passes through the water layer and moves to the upper side of the liquid-liquid separator 30.

At this time, as shown in FIG. 3, a relatively fine mesh 31c is provided at the distal end opening of the small-diameter pipe 31b to prevent the generation of bubbles having a large diameter by the transported air, Thereby uniformly distributing it.

On the other hand, Fig. 4 shows another embodiment of this airflow distribution port 31. Fig. As shown in the drawing, the small-diameter tube 31b of the airflow distribution opening 31 according to the present embodiment is formed in a semicircular or 'C' -shaped circular arc shape in which one side is opened, In the case where the cross section of the small-diameter pipe 31b is circular and the side faces are closed, the discharge pressure of the conveyed air can rise, so that the deceleration effect in the water is lowered and water may be scattered. In order to alleviate such a problem, a part of the small-diameter pipe 31b is formed as an open type so as to lower the pressure, so that smooth discharge of the conveyed air, smooth deceleration effect and separation effect can be obtained.

On the other hand, the water stored in the lower portion of the liquid-liquid separator 30 is preferably maintained at a constant water level at all times. When the water level becomes too high, the air discharged from the small-diameter pipe 31b is not transferred to the upper side of the liquid-liquid separator 30 due to the high water pressure. If the water level becomes too low, the combined liquid of chemical liquid micro- And is transported upward with the air, which is not preferable. Repeated experiments show that the water level of the stored water is about 20 to 30 cm. To this end, it is preferable that the liquid-liquid separator 30 is provided with a water level sensor 32, a supplementary water pipe 36 on one side, and a drain pipe 33 on the lower side. It is preferable that a solenoid valve is provided in each of the supplemental water pipe 36 and the drain pipe 33. Accordingly, when the water level sensor 32 senses the water level in real time and the water level of the water level sensor 36 rises above the appropriate water level, the solenoid valve of the water pipe 33 is opened to discharge water. The solenoid valve is opened so that the water level can be kept constant by replenishing the replenishing water. In addition, the liquid-liquid separator 30 is further provided with a water quality sensor 37. When the water stored due to the repeated recovery of odor components is excessively contaminated to a predetermined value or more, the solenoid valve of the water discharge pipe 33 is opened So that the solenoid valve of the replenishing water pipe 36 after discharge is opened to fill the clean replenishing water.

Preferably, a fryer 34 is provided on the water surface of the liquid-liquid separator 30. The frying stopper 34 is made of a porous material capable of intercepting and absorbing a mesh net or water to prevent the water from splashing upward due to the pressure of the feed air discharged from the airflow distribution port 31, So that the odor component combined air and the separated air can be transported upward.

A demister 35 is additionally provided on the fryer chamber 34. The demister 35 absorbs and removes the combined substance of the chemical liquid micro droplets and the odor component remaining in the air without being recovered from the water stored in the lower part of the liquid-crystal separator 30, thereby preventing the odor component from being discharged to the atmosphere. The air that is finally filtered by the demister 35 is discharged to the outside.

In this way, odorous components are separated and recovered by being combined with micro liquid droplets, and only clean air is discharged to the outside, thereby reducing the odor generated in the automatic garbage collection equipment.

FIG. 2 shows a droplet-separating odor reduction apparatus according to another preferred embodiment of the present invention. In the embodiment shown in FIG. 1, the chemical liquid injector 10, the airflow accelerating unit 20 and the liquid-liquid separator 30 are formed as separate housings and are connected to each other in a modular fashion, In this example, the chemical liquid injector 10, the airflow accelerating unit 20 and the liquid-liquid separator 30 are integrally formed as a housing, and the inside is divided by the partition walls to form a flow path to transfer the transferred air. However, only the liquid-liquid separator 30 is completely separated by the air-flow accelerating part 20 and the partition wall, and is connected to each other by the large-diameter pipe 31a of the air flow distribution port 31. [ Other configurations and operating methods of the embodiment shown in FIG. 2 are the same as those shown in FIG. 1, and thus detailed description will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited by these exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
