Embodiment
A kind of energy-saving vent cabinet that the present embodiment proposes, it includes：Cabinet, exhaust blower 4 and exhaust duct 2, exhaust duct 2
Air inlet connects with the air outlet of exhaust blower 4, and the exhaust outlet 6 of exhaust duct 2 is towards outside cabinet.The vent cabinet also includes being located at air draft
Circulating line 3 in pipe 2, and the filter 5 for filtering poisonous gas.Wherein, the direction of the air inlet of the circulating line 3 with
The air draft direction of exhaust duct 2 is on the contrary, the air outlet of the circulating line 3 connects with the air inlet of filter 5；The air-out of filter 5
Mouth connects with the workspace 1 of cabinet.
The caused toxic gas in experimentation of workspace 1 by exhaust blower 4, is expelled to outside cabinet through exhaust duct 2.By
It is located in circulating line 3 in exhaust duct 2, and the air inlet direction of circulating line 3 is opposite with the air draft direction of exhaust duct 2.Therefore,
Part toxic gas in exhaust duct 2 can flow into circulating line 3, and flow to filter 5 through circulating line 3.Filter 5 will be poisonous
After gas filtration, output clean gas reuses into the workspace 1 of cabinet, reaches the purpose of energy-conservation.It should be noted that
It is middle compared with prior art to realize circulation because this vent cabinet increases circulating line 3 and filter 5 only on the basis of original structure
The equipment of return air, the structure of the application is simple, and cost is relatively low.
Further, circulating line 3 includes：The elbow 302 that the air inlet of airduct 301 and airduct is detachably connected.Its
In, the direction of the air inlet of elbow 302 is with the air draft direction of exhaust duct 2 on the contrary, the air outlet of airduct 301 and entering for filter 5
Air port connects.It should be noted that because elbow is demountable, when needing to adjust the amount of circulation return air, staff
The elbow 302 of different air inlet bores can be changed, to adjust the section area ratio of the air inlet of elbow 302 and the caliber of exhaust duct 2.
In the present embodiment, 2 a diameter of 250mm of exhaust duct, sectional area is 0.0491 square metre.It can need to select according to experiment
Select the elbow 302 of two kinds of models of a, b：
A. a diameter of 137mm is selected, sectional area is 0.0147 square metre of elbow 302, circulates the air inlet section of airduct 3
Product accounts for the 30% of the sectional area of exhaust duct 2, so, can import circulation airduct 3 by the air-flow about 30% of exhaust duct 2, then lead to
Cross filter 5 and be recycled to workspace 1, remaining 70% is discharged by exhaust outlet 6；
B. a diameter of 209mm is selected, sectional area is 0.0344 square metre of elbow 302, circulates the air inlet section of airduct 3
Product accounts for the 70% of the sectional area of exhaust duct 2, so, can import circulation airduct 3 by the air-flow about 70% of exhaust duct 2, then lead to
Cross filter 5 and be recycled to workspace 1, remaining 30% is discharged by exhaust outlet 6；
Further, in order that obtaining circulation return air can uniformly be circulated in workspace 1, the inwall of cabinet offers air channel
8, and the air channel 8 connects with the air outlet of filter 5, at the madial wall and the front edge of workspace 1 of the workspace 1 of the cabinet
Some air vents 7 are offered, some air vents 7 connect with the air channel 8.The clean gas that filter 5 exports passes through wind
Road 8 and air vent 7 are back in workspace 1.
Further, exhaust duct 2 and the circulating line 3 set up are PP plates.
Further, exhaust blower 4 is axial flow blower.
Further, filter 5 is box HEPA filters.
Preferred embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, it is every
