The cleaning part 120 sprays a cleaning liquid to the malodor gas introduced from the gas inlet 110 to clean the malodorous gas.

The number of the cleaning units 120 may be plural. In the present invention, the number of the cleaning units 120 is two. However, the cleaning units 120 may be formed more than necessary. For example, the cleaning section 120 includes a first cleaning section 121 for primarily cleaning the malodorous gas and a second cleaning section 122 for cleaning the odorous gas.

The first cleaning part 121 includes a first cleaning chamber 121a through which the malodorous gas flows, a first water tank 121b located below the first cleaning chamber 121a and containing a first cleaning liquid, A first supply pipe 121c for supplying the first rinsing liquid to the first rinsing chamber 121a by using the pump P1 and a second supply pipe 121c connected to the first supply pipe 121c to supply the first rinsing liquid to the first rinsing chamber 121a And a first spray nozzle 121d for spraying the odor gas introduced into the spray nozzle 121d. The malodor gas introduced from the gas inlet 110 is supplied to the first cleaning chamber 121a and is cleaned by the first cleaning liquid injected through the first spray nozzle 121d, ). In addition, the first cleaning chamber 121a is formed in a ring shape having a substantially hollow center, and the odor gas introduced into the first cleaning chamber 121a rotates the first cleaning chamber 121a, And sufficient reaction occurs.

The second cleaner 122 is disposed above the first cleaner 121 and includes a second cleaner chamber 122a through which the malodor gas firstly cleaned by the first cleaner 121 flows, A second water tank 122b located below the second cleaning chamber 122a and containing the second cleaning liquid and a second pump P2 for supplying the second cleaning liquid to the second cleaning chamber 122a, And a second spray nozzle 122d connected to the second supply pipe 122c and the second supply pipe 122c for spraying the second cleaning liquid onto the odor gas introduced into the second cleaning chamber 122a. The odor gas primarily cleaned from the first cleaning section 121 is supplied to the second cleaning chamber 122a and is cleaned by the second cleaning liquid injected through the second spray nozzle 122d. The second cleaning chamber 122a is formed in the shape of a ring which is substantially centered in the same manner as the first cleaning chamber 121a and the odor gas introduced into the second cleaning chamber 122a flows into the second cleaning chamber 122a, The cleaning chamber 122a rotates and sufficiently reacts with the second cleaning liquid. In addition, an internal discharge passage 140, which will be described later, is located in the empty space in the center of the first cleaning chamber 121a and the second cleaning chamber 122a.

Thus, the gas having the odor removed through the first washing section 121 and the second washing section 122 is discharged through the gas discharging section 150. A discharge port 123 is formed between the second cleaning chamber 122 and the gas discharge unit 150 so that gas can be discharged. The discharge port 123 is opened normally and the odor-free gas in the second cleaning chamber 122a passes through the discharge port 123 and is discharged to the outside through the gas discharge unit 150 . Here, it refers to a state in which the malodor is removed by the lancet 120 in the normal state, and the malodor concentration of the malodor gas is lower than the reference value (i.e., harmless even if the gas is discharged to the outside).

The re-suction unit 130 includes a concentration detecting unit 131 capable of measuring the concentration of the malodor contained in the malodorous gas and a gas suction unit 132 for re-sucking malodorous gas located in the cleaning unit 120 do.

The concentration detecting unit 131 is located at an upper end of the cleaner 120 and measures the odor concentration of the cleaned gas through the cleaner 120. For example, the concentration sensing unit 131 is disposed at the uppermost end of the cleaning unit 120, that is, in the second cleaning chamber 122a, and measures the odor concentration of the cleaned gas. When the concentration of the odorous gas measured by the concentration sensing unit 131 is lower than the reference value, the gas moves to the gas discharge unit 150 through the discharge port 123 as shown in FIG. On the other hand, if the concentration of the measured odorous gas concentration in the concentration detecting unit 131 is higher than the reference value, the gas is sucked again by the gas suction unit 132 and then cleaned again as shown in FIG. In this case, the outlet 123 is closed (closed) in order to prevent a gas having a high odor concentration from being discharged to the outside.

The gas suction part 132 is located in the water tanks 121b and 122b of the cleaning part 120. [ More specifically, as shown in FIG. 5, a plurality of gas suction units 132 may be installed in the first water tank 121b and the second water tank 122b containing the cleaning liquid. The gas suction units 132 are installed in the first and second water tanks 121b and 122b at a predetermined interval. The gas sucking unit 132 includes a first supply pipe 132a through which the cleaning liquid in the water tanks 121b and 122b is supplied by operation of the pump and a second supply pipe 132a through which the malodor gas located in the second cleaning chamber 122a is supplied. (132b). The second supply pipe 132b is provided with a connection pipe 133 connected to the second cleaning chamber 122a so that odorous gas located in the second cleaning chamber 122a is supplied by the operation of the pump . 6, the second supply pipes 132b of the plurality of gas suction units 132 are connected to each other by a first auxiliary pipe 134 connected in the vertical direction from the connection pipe 133 And the first supply pipe 132a may be connected to each other by the second auxiliary pipe 135. [ Accordingly, the plurality of gas suction portions 132 can be operated simultaneously by one pump. Specifically, when the cleaning liquid is supplied to the first supply pipe 132a by the pump, the gas suction unit 132 is connected to the second cleaning chamber 132b through the second supply pipe 132b with a negative pressure generated thereby, It is possible to suck the malodorous gas located in the first chamber 122a. For example, the gas suction unit 132 may include an ejector or an air jet, but the present invention is not limited thereto.

As described above, the gas suction unit 132 re-sucks the malodorous gas having the odor concentration higher than the reference value in the second cleaning chamber 122a and supplies it to the first water tank 121b and / or the second water tank 122b , So that the malodor gas can react with the cleaning liquid again. That is, the gas sucking part 132 re-sucks the malodorous gas having a malodor concentration higher than the reference value and passes through the cleaning part 120, thereby cleaning the malodorous gas with the cleaning liquid.

In addition, the pump for driving the gas suction unit 132 may use the first and second pumps P1 and P2 for supplying the cleaning liquid in the water tanks 121b and 122b to the first and second supply pipes 121c and 122c have. In other words, the gas suction part 132 provided in the first water tank 121b is connected to the first pump P1, and the gas suction part 132 provided in the second water tank 122b is connected to the second pump P1, (P2). That is, the first and second pumps P1 and P2 supply the washer fluid to the first and second supply pipes 121c and 122c and the gas suction unit 132 to drive the first and second pumps P1 and P2. Gas can be supplied to the first and second water tanks 121b and 122b. Of course, the pump for driving the gas suction unit 132 may be installed separately from the first and second pumps P1 and P2.

The internal discharge passage 140 is formed in the center of the first and second cleaning chambers 121a and 122a and is formed on the first and second water tanks 121b and 122b. Specifically, the internal discharge passage 140 is formed in a hollow space in the center of the first and second cleaning chambers 121a and 122a, and is separated from the first and second cleaning chambers 121a and 122a. The internal discharge passage 140 is a passage through which the gas cleaned again by the cleaning liquid in the water tanks 121b and 122b is sucked by the gas suction part 132 again. The gas that has passed through the internal discharge passage 140 is discharged to the outside through the gas discharge unit 150. In addition, the internal exhaust passage 140 may be further provided with additional odor elimination equipment (for example, a filtration device such as an adsorption filter or a dust filter, a sterilizing device, a heating device, a deodorizing device, and the like).

The gas discharge unit 150 is located above the cleaning unit 120 and the internal discharge passage 140. The gas discharge unit 150 discharges the gas that has been cleaned through the cleaning unit 120 or the gas that has been cleaned again by the re-suction unit 130 to the outside.

The pretreatment unit 160 is positioned between the gas inlet 110 and the cleaner 120. The pretreatment unit 160 previously cleans the malodor gas introduced by the gas inlet 110 with water before sending it to the cleaning unit 120. The pretreatment unit 160 supplies water to the malodorous gas so that the malodorous gas reacts with moisture. For example, the pretreatment unit 160 includes a plurality of rotating plates. The rotating plate is rotated by the malodorous gas supplied from the gas inlet 110, and water is supplied to the rotating plate, Can be formed to react with water. The structure of the pretreatment unit 160 is not limited to that described above, and any structure may be used as long as it is capable of reacting with malodorous gas and water. As described above, according to the present invention, since the malodorous gas is pre-treated by the pretreatment unit 160 before the malodor gas is sent to the cleaning unit 120, the replacement period of the cleaning liquid can be increased, and the cost can be reduced.

As described above, since the malodor removing apparatus 100 according to the present invention includes the re-suction unit 130, it can be recycled and recycled according to the odor concentration of the cleaned gas, have. In addition, the present invention can maximize space efficiency by installing the re-suction unit 130 in a conventional washing tower instead of a separate tower.

It is to be understood that the present invention is not limited to the above-described embodiment, and that various modifications and changes may be made without departing from the scope of the present invention as defined in the appended claims. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
