One end of the soot separating device 10 is closed to form a closed end 12, and the other end is open to form an open end 14, and the soot separating device 10 is The side wall is provided with a plurality of air inlets 162 at the closed end 12 and the open end 14. The soot separating device 10 includes a plurality of rectifying portions 16, each rectifying portion 16 is connected to a corresponding one of the air inlet 162 and the open end 14 The port 142, each rectifying portion 16 includes a rectifying passage 163 that is at an acute angle a to the tangential direction at the inlet port 162.

The soot separating device 10 of the embodiment of the present invention may be disposed upstream of the airflow of the fan of the exhaust device 100, and the soot is rectified by the rectifying passage 163 of the rectifying portion 16 to have tangential velocity and radial velocity, so that particles and droplets in the soot are made. Under the action of inertia, it will be separated from the moving direction of the airflow, and collide with the wall of the flue 20 of the smoke exhausting device 100 to adhere thereto. Therefore, the soot is effectively separated before the fume passes through the fan, thereby reducing the adhesion of the fume on the fan. In turn, the user's cleaning burden is reduced.

Specifically, the soot flow enters the rectifying passage 163 of the soot separating device 10 from the plurality of intake ports 162, and the soot particles can adhere to the inner wall of the rectifying passage 163 after being separated from the air flow by inertia, and the air flow flows along the rectifying portion 16 to the soot. The open end 14 of the separating device 10, at which time the soot content in the outflowing airflow has been greatly reduced. Due to the arrangement of the rectifying passage 163, after the airflow exits the soot separating device 10, the soot flow will be in the upper portion of the flue 20 of the exhausting device 100. Columnar space A swirling flow is formed in the inside, because the soot flow continuously changes the direction of movement, in which the soot particles will deviate from the direction of movement of the airflow under the action of inertia, and collide with the wall surface of the flue 20 to adhere, and also increase the soot. The opportunity for the particles to collide with each other, thereby forming larger particles, is more likely to adhere to the wall of the flue 20.

Further, when the soot separating device 10 according to the embodiment of the present invention is applied to the exhausting device 100, the soot separating device 10 may be integrally attached to the existing exhausting device 100 or may be a part of the new exhausting device 100.

In the embodiment of the present invention, the soot separating device 10 has a cylindrical shape as a whole.

Referring to FIGS. 1 to 3, in some embodiments, the soot separating device 10 includes a bottom plate 122, a top plate 144 and a plurality of side plates 18, the bottom plate 122 serves as a package end, the top plate 144 serves as an open end 14, and the rectifying portion 16 is connected thereto. Between the bottom plate 122 and the top plate 144, the plurality of side plates 18 are spaced apart from the outer edge of the bottom plate 122 and the outer edge of the top plate 144, and the adjacent two side plates 18 form an air inlet 162.

Thus, the soot enters the rectifying portion 16 formed between the top plate 144 and the bottom plate 122 from the air inlet 162, and the soot particles can adhere to the inner wall of the rectifying passage 163 after being separated from the air flow by the inertia.

Specifically, the side panels 18 are fixedly mounted on the top panel 144 or the bottom panel 122.

In certain embodiments, the acute angle a is greater than 20 degrees.

In this way, after the oily gas flow enters the rectifying portion 16, the flow direction of the soot gas flow changes. When the acute angle is greater than 20 degrees, neither excessive resistance nor the flow direction of the soot gas flow can be changed, so that the soot gas flow rotates upward, and The soot particles mixed in the soot gas stream are separated from the soot gas stream by the inertia and adhere to the inner wall of the rectifying passage 163.

Specifically, each of the rectifying passages 163 is equal to an acute angle formed by a tangential direction at the corresponding intake port 162.

In certain embodiments, the rectifying passage 163 is enclosed by two baffles 164, each baffle 164 being at an acute angle a to the tangential direction at the inlet 162.

As such, the rectification channel 163 is implemented in a relatively simple structure.

In some embodiments, the two baffles 164 include a first baffle 1642 and a second baffle 1644. The first baffle 1642 is fixedly coupled to the bottom plate 122, and the second baffle 1644 is fixed to the top plate 144. connection.

In this way, when the soot attached in the soot separating device 10 needs to be cleaned, the soot separating device 10 can be easily and quickly disassembled. Since the first baffle 1642 and the second baffle 1644 are spaced apart, the cleaning space is also enlarged, which is convenient. Cleaning.

After the cleaning is completed, The top plate 144 and the second baffle plate 1644 fixed on the top plate 144 are placed on the bottom plate 122 and the first baffle plate 1642 fixed on the floor, so that the two parts can be installed, and the disassembly and assembly process is simple and convenient.

Referring to FIG. 2, in some embodiments, along the direction A of the acute angle α, the two baffles 164 are the first baffle 1642 and the second baffle 1644, and the length of the first baffle 1642. Greater than the length of the second baffle 1644.

In this manner, the rectifying passage 163 formed by the rectifying portion 16 is made longer, and the rectified soot speed is higher.

Specifically, the first baffle 1642 is spaced apart from the second baffle 1644, and the soot flow enters the first baffle 1642 and the second baffle 1644 from the air inlet 162 to restrict the formed rectifying passage 163, the soot flow When the flow direction is changed for the first time, when the length of the first baffle 1642 is greater than the length of the second baffle 1644, when the soot flow flows to the end of the rectifying passage 163, it collides with the phase on the inclined side of the baffle 164. The adjacent first baffle 1642 causes a portion of the soot particles to adhere to the first baffle 1642 and a second change in the direction of the soot flow to cause the soot flow to rotate upward.

In certain embodiments, the first baffle 1642 is parallel to the second baffle 1644.

In this way, the rectifying passages 163 formed by the first baffles 1642 and the second baffles 1644 which are parallel to each other can rectify the direction and size of the soot flow.

3 and FIG. 4, the smoke evacuation device 100 according to the embodiment of the present invention includes the soot separation device 10 and the flue 20 of any of the above embodiments, and the open end 14 is sealed to the inner wall of the flue 20.

The soot separating device 10 of the embodiment of the present invention may be disposed upstream of the airflow of the fan of the exhaust device 100, and the soot is rectified by the rectifying passage 163 of the rectifying portion 16 to have tangential velocity and radial velocity, so that particles and droplets in the soot are made. Under the action of inertia, the direction of movement of the airflow is released, and it collides with the wall of the flue 20 of the smoke exhausting device 100 to adhere. Therefore, the soot is effectively separated before the oil smoke passes through the fan, which reduces the adhesion of the soot on the fan, thereby reducing the user's cleaning burden.

Specifically, after the soot gas flow out from the soot separating device 10, due to the structure of the soot separating device 10, the soot gas flow rotates upward and flows, and the soot particles will deviate from the moving direction of the air flow under the action of inertia, and collide with the wall surface of the flue 20 to adhere thereto. Attached to the inner wall of the flue 20. When the soot flows through the soot separation device 10, a part of the soot particles have adhered to the inner wall of the rectification passage 163, and the soot flow from the soot separation device 10 contains a relatively small amount of soot particles, and a small amount of soot particles rotate in the soot flow. The flow adheres to the inner wall of the flue 20, prolongs the cleaning cycle of the inner wall of the flue 20, and the inner wall of the flue 20 has a large structure and can be directly cleaned without disassembly.

In one example, the smoke evacuation device 100 is, for example, a range hood.

In certain embodiments, the soot separating device 10 is detachably mounted on the inner wall of the flue 20.

Thus, when the cleaning is required, the soot separating device 10 is detached from the flue 20, and the structure is simple and the disassembly is convenient.

The soot separating device 10 is disposed in the condensing direction along the soot flow direction. Downstream of the plate 40, the flue 20 is connected to the hood 30.

Thus, when the soot passes through the condensing plate 40, a small portion of the soot particles condense on the condensing plate 40. After the soot gas stream enters the exhaust device 100, three soot separations are performed, respectively, in the condensing plate 40, the soot separating device 10 and the flue 20, and the flue gas particles discharged from the flue gas discharging device 100 have a low content of soot particles, which can protect the atmospheric environment.
