Abstract
The utility model relates to a gas exhausting channel for a multi storey building, which comprises a main air channel penetrating each storey from bottom to top. The wall of the main air channel is provided with a gas inlet communicated with each storey. The utility model is characterized in that one side wall of the main air channel is connected with a line of rising gas guide plates. The upper and lower adjacent rising gas guide plates form a branch air channel of which the outlet section is smaller with the front side wall and the rear side wall of the main air channel; the middle lower part of the branch air channel is communicated with the gas inlet, the upper end of each rising gas guide plate is positioned between the left side wall and the right side wall of the main wind channel. The gas exhaust passage can effectively prevent the phenomenon that the smoke and the odor mutually runs in each storey in disorder from happening and has big popularization and application value.
Description
The utility model relates to the exhaust duct that a kind of multi-storey building is used.
The smoke vent that existing a kind of multi-storey building is used has the air inlet port that communicates with each floor on its perisporium, the shortcoming of existence mainly be when certain floor through air inlet port when smoke vent is got rid of flue gas, this flue gas can enter this floor through the air inlet port of other contiguous floors usually.Thereby produce the phenomenon that mutual smoke blowing is collaborated and distinguished the flavor of.
The purpose of this utility model is the exhaust duct that will provide a kind of multi-storey building to use, and it can effectively prevent the mutual smoke blowing of each floor.The phenomenon of distinguishing the flavor of of collaborating takes place.
The utility model is to constitute like this, it comprises the main air duct that runs through each floor from bottom to top, offer the air inlet port that is connected with each floor on the main air duct wall, it is characterized in that: be connected with one on main air duct one sidewall and list and raise aeroscopic plate, the forward and backward sidewall of two upper and lower adjacent raise up aeroscopic plate and main air ducts forms the less branch air duct in outlet, branch air duct middle and lower part and air inlet port link, and the upper end of the aeroscopic plate that raises up is between the left and right sidewall of main air duct.
When the flue gas (by blower fan) of certain floor after air inlet port and the branch air duct that raises up enter main air duct, form upwards airflow flowing in the main air duct, during the outlet of the branch air duct of these other floors of airflow passes, owing to produce jet action, the air pressure that makes the branch air duct exit is lower than the air pressure at this floor air inlet port place, therefore the flue gas on the main air duct just can not scurried into other floor through other branch air duct, thereby can effectively prevent the phenomenon generation that mutual smoke blowing is collaborated and distinguished the flavor of.
Fig. 1 is the utility model embodiment one organigram.
Fig. 2 is the A-A sectional drawing of Fig. 1.
Fig. 3 is embodiment two organigrams.
Below in conjunction with drawings and Examples the utility model is specifically described.
See figures.1.and.2, the utility model comprises the main air duct 1 that runs through each floor from bottom to top, offer the air inlet port 3 that is connected with each floor on the main air duct wall, it is characterized in that: be connected with one on main air duct one sidewall and list and raise aeroscopic plate 5, the forward and backward sidewall 7.8 of two upper and lower adjacent raise up aeroscopic plate and main air ducts forms the less branch air duct 2 in outlets, branch air duct middle and lower part and air inlet port 3 link, and the upper end of the aeroscopic plate that raises up is between the left and right sidewall 6.4 of main air duct.
The above-mentioned aeroscopic plate lower end that raises up is provided with zigzag part, and the two upper and lower adjacent aeroscopic plates that raise up parallel.
Embodiment two structure as shown in Figure 3, the difference of it and embodiment one only is that the former air inlet port 3 is to be opened on the left side wall 6 of main air duct, the latter's air inlet port 9 is to be opened on the rear wall of main air duct.
The utility model is novel, and is reasonable in design, has bigger application value.
Claims (2)
1. exhaust duct that multi-storey building is used, comprise the main air duct that runs through each floor from bottom to top, offer the air inlet port that is connected with each floor on the main air duct wall, it is characterized in that: be connected with one on main air duct one sidewall and list and raise aeroscopic plate, the forward and backward sidewall of two upper and lower adjacent raise up aeroscopic plate and main air ducts forms the less branch air duct in outlet, branch air duct middle and lower part and air inlet port link, and the upper end of the aeroscopic plate that raises up is between the left and right sidewall of main air duct.
2. the exhaust duct that multi-storey building according to claim 1 is used is characterized in that: the aeroscopic plate lower end that raises up is provided with zigzag part, and the two upper and lower adjacent aeroscopic plates that raise up parallel.
