1 to 3, the apparatus for removing odorous substances using a shaft 10 removes foreign substances and odor substances contained in the air exhausted from the housing 20 and discharges the air from which the foreign substances and the odor substances have been removed to the outside do. Generally, in the housing 20, an exhaust port 21 for discharging the internal air to the outside is formed in the side wall 22 for ventilation. The exhaust port (21) is provided with an exhaust fan (23) for forcibly exhausting the internal air to the outside. The exhaust port 21 and the exhaust fan 23 may be provided along the side wall 21 of the housing 20 so as to be spaced apart from each other. The apparatus for removing odorous substances 10 removes foreign substances and odor substances contained in air forcedly discharged from the exhaust ports 21 described above.

The malodorous substance removal device 10 includes an exhaust duct 110, a housing 130, a first injection nozzle 141, second injection nozzles 142 and 143, a discharge pipe 150, an external air supply unit 160, An air flow regulator 170, a rainwater receiver 180, a fluid receiver 210, and a fluid regeneration unit 220.

The exhaust duct 110 is formed therein with a flow path through which the air a1 flows. One end of the exhaust duct 110 is connected to the exhaust port 21 and the other end is connected to the housing 130. The air a1 exhausted from the exhaust port 21 flows into the housing 130 through the exhaust duct 110.

The exhaust duct 110 is connected to the cylindrical region 131 of the housing 130 and disposed in the tangential direction of the cylindrical region 131. The air a3 flowing through the exhaust duct 110 flows along the inner surface of the cylindrical region 131 to form a rotary flow.

The exhaust duct 110 has a flow rate increasing section 111 and an air inlet 112. The flow rate increase section 111 is formed between the end of the exhaust duct 110 and a point where the first injection nozzle 141 is located. The flow rate increase section 111 is a section where the flow passage is narrower than other sections, and the pressure is lower and the flow rate is formed faster than other sections.

The air inlet 112 is a path connecting the inside and the outside of the exhaust duct 110 and is formed between the flow rate increasing section 111 and a point where the first injection nozzle 141 is located. According to the embodiment, the air inlet 112 is located adjacent to the first injection nozzle 141. The air inlet 112 is formed to be inclined toward the center of the flow rate increasing section 111 in the flow direction of the air a1 in the exhaust duct 110. [ The pressure in the front region of the first injection nozzle 141 is instantaneously lowered by the force of the fluid L injected from the first injection nozzle 141. [ This pressure reduction causes the outside air a2 to flow into the exhaust duct 110 through the air inlet 112. [ The outside air a2 flows in the flow direction of the air a1 in the exhaust duct 110 so that the flow of the air a1 in the exhaust duct 110 is smooth.

The housing 130 has a space therein in which the air a3 is introduced from the exhaust duct 110. [ The inner space of the housing 130 has a cylindrical region 131 and a funnel-shaped region 132.

The cylindrical region 131 has a cylindrical shape with a predetermined radius, and air flows from the exhaust duct 110.

The funnel-shaped region 132 is located below the cylindrical region 131 and has a shape in which the width of the space is gradually narrowed from the top to the bottom.

The air a3 flowing into the housing 130 from the exhaust duct 110 forms a rotational flow along the inner surface of the cylindrical region 131 as shown in Figures 3 and 4 and then flows into the funnel- The radius of rotation gradually decreases while rotating along the inner surface. This rotational flow causes a rapid and smooth flow of air a3 to the bottom surface of the housing 130. [

The first injection nozzle 141 is provided in the exhaust duct 110. The first injection nozzle 141 injects the fluid L1 in the flow direction of the air a1 in the exhaust duct 110. [ The first injection nozzle 141 injects the fluid L1 in a mist state. According to the embodiment, the first injection nozzle 141 may be an atomizer. The force to which the fluid L1 is injected smoothly flows the air a1 in the exhaust duct 130. [ According to the embodiment, water may be used as the fluid L1. The sprayed water particles L1 absorb hydrophilic particles, for example, ammonia particles, of odor substances contained in the air a1. In addition, the water particles L1 are adsorbed to a foreign substance such as dust contained in the air a1. The foreign matter adsorbed by the water particles (L1) and the water particles (L1) absorbed by the ammonia particles flows into the housing (130).

The second injection nozzles 142 and 143 are provided in the housing 130. A plurality of second injection nozzles 142 and 143 are provided and are located along the inner surface of the housing 130. The second injection nozzles 142 and 143 are disposed on the air a3 flow path in the housing 130 and inject the fluid L2 in the flow direction of the air a3. The force to which the fluid L2 is injected smoothes the rotational flow of the air a3 in the housing 130. [ The second injection nozzles 142 and 143 spray the fluid L2 in a mist state. The second injection nozzles 142 and 143 may be provided with the same nozzle as the first injection nozzle 141. According to the embodiment, water may be used as the fluid L2. The injected water particles L2 absorb the hydrophilic particles flowing together with the air a3 in the housing 130 and adsorbed on the foreign matter contained in the air a3.

The water particles L1 and L2 staying in the air a1 and a3 due to the multiple injection of the water particles L1 and L2 using the first injection nozzle 141 and the second injection nozzles 142 and 143 And the foreign matter adheres to the inner surface of the housing 130 or falls to the bottom due to the weight of the adsorbed water particles L1 and L2. In this process, odor substances and foreign substances contained in the air (a1, a3) are recovered to the bottom of the housing 130 by the water particles L1, L2. The number of collisions between the water particles L1 and L2 and the odorous substances and the number of collisions between the water particles L1 and L2 and the foreign substances increase as the space of the housing 130 approaches the bottom surface . Thus, it is possible to sufficiently remove odorous substances and foreign substances contained in the air (a1, a3).

The outlet pipe 150 is a tube having an inlet 151 and an outlet 152. The inlet 151 is located inside the housing 130 and the outlet 152 is located outside the housing 130. According to an embodiment, the inlet 151 is located in the funnel-shaped region 132 of the housing 130. The air a3 which has moved to the bottom of the funnel-shaped region 132 by the rotational flow flows into the inlet 151 of the discharge pipe 150 and flows along the discharge pipe 150 and is discharged outside through the discharge port 152. [ According to the embodiment, the discharge tube 150 is disposed such that its longitudinal direction is parallel to the up-and-down direction. The air a4 moves to the upper portion of the housing 130 along the discharge pipe 150 and is discharged to the outside. While the air a4 moves along the discharge pipe 150, water particles that have not been recovered in the housing 130 are collected on the inner surface of the discharge pipe 150 and recovered to the bottom of the housing 130 by their own weight .

The outside air supply unit 160 forcibly supplies the outside air a5 in the flow direction of the air a4 in the discharge pipe 150. [ The external air supply unit 160 includes an external air supply pipe 161 and an external air supply fan 165.

One end of the external air supply pipe 161 is connected to the discharge pipe 150, and the other end is opened to the outside. The external air supply pipe 161 may be connected to the discharge pipe 150 at an upper portion of the housing 130. The external air supply pipe 161 is provided with an upwardly inclined outlet 162 for supplying air a5 into the discharge pipe 150. [

The external air supply fan 165 is installed in the external air supply pipe 161 and forcibly blows the external air a5 to the outlet 162 side.

The forced air blowing and discharging port 162 of the external air supply fan 165 supplies the external air a5 in the flow direction of the air a4 in the discharge pipe 150, (a4) The flow is smooth.

The air flow regulating part 170 weakens the turbulent flow of the air a4 flowing along the discharge pipe 150. The air a3 having a rotational flow in the housing 130 may still have a rotational flow, i.e., a turbulent flow, in the outlet tube 150. [ The air flow regulator 170 weakens the turbulent flow of this air a4. According to an embodiment, the air flow regulator 170 may be located adjacent the top of the discharge tube 150.

5 is a plan view showing an air flow regulating part according to an embodiment of the present invention.

2 to 5, the air flow regulating portion 170 includes a support portion 171 and a partition plate 172.

The support portion 171 has a predetermined height, and the discharge pipe 150 is located at the center. The partition plates 172 are plates having a thin thickness, and are arranged radially about the supports 171. One end of the partition plate 172 is connected to the support 171 and the other end of the partition plate 172 is connected to the inner surface of the discharge pipe 150. The partition plates 172 may have a height corresponding to the support portion 171. The partition plates 172 are arranged so that their height directions are parallel to the up and down directions. The air a4 flowing along the discharge pipe 150 passes through the space between the partition plates 172. In the process of passing through the space between the partition plates 172, the air a4 of the turbulent flow hits the partition plates 172, flows along the height direction of the partition plates 172, and is aligned. This can weaken the turbulent flow of the air a6.

The rainwater receiver 180 is provided on the upper portion of the discharge pipe 150 and maintains a predetermined distance from the upper end of the discharge pipe 150. The air a6 flowing out of the discharge pipe 150 is discharged to the outside through the space between the rainwater receiver 180 and the upper end of the discharge pipe 150. [ The rainwater receiver 180 blocks rainwater from flowing into the discharge pipe 150.

The fluid receiving portion 210 is mounted on the bottom surface of the funnel-shaped region 132. The fluid receiving portion 210 collects the fluid recovered in the housing 130. As described above, the fluid to be recovered is water containing odorous substances and foreign matter.

The fluid regeneration unit 220 removes foreign matter from the water collected in the fluid receiving unit 210 and supplies the water with the foreign substance to the first injection nozzle 141 and the second injection nozzles 142 and 143 again.
