Abstract
The utility model relates to a pressure changing gas exhausting structure of a high-rising building, which is mainly composed of a branch pipeline (2), a first main pipeline (1), a second main pipeline (3), air inlet (5), (6), (8), (9) and corresponding exhaust outlet (4), (7), (10), (11), wherein the first main pipeline (1) and the second main pipeline (3) are abreast arranged at both sides of the branch pipe (2). The air inlets (5), (6), (8), (9) are arranged between the branch pipe (2) and rooms in floors. A dustpan-shaped exhaust guiding pipe is respectively arranged at every exhaust outlet parts; corresponding pressure changing components are arranged on the opposite faces of the guiding pipes or adjacent wall faces. The structure decreases the resistance of exhaust passages to airflow, and is good for discharging indoor gas. The utility model solves the problem of mutual smoke and taste cross among rooms in floors, and is mainly used for discharging gas in rooms of high-rising buildings.
Description
The utility model relates to a kind of indoor exhaust device of building, the pressure variable exhausting channel structure of particularly a kind of high-rise building (building more than ten layers).
The high-rise building exhaust duct of people's use at present, be that steam vent by two smaller aperture due that are arranged side by side constitutes, its shortcoming is, steam vent is bigger to the gas-flow resistance of indoor discharge, and each floor is indoor all directly to communicate with above-mentioned steam vent by corresponding air inlet port, therefore easily produces the phenomenon of the indoor mutual smoke blowing of each floor, taint of odour.
Task of the present utility model is, improves the exhaust duct for building structure, to reduce the resistance of exhaust duct to indoor exhaust jet stream, avoid simultaneously each floor indoor between the generation of smoke blowing mutually, taint of odour phenomenon.
In order to finish above-mentioned task, the solution that the utility model is taked is, it comprises trunk line, branch pipe(tube) and air inlet port, trunk line and branch pipe(tube) are arranged side by side, be characterized in, the trunk line that is arranged side by side has two, and above-mentioned two trunk lines are arranged side by side the both sides at described branch pipe(tube) respectively, constitutes the structure that three pipelines are arranged side by side.Above-mentioned two trunk lines and a branch pipe(tube) one section joint that constitutes exhaust duct respectively separately, after each saves the exhaust duct butt joint, make two trunk lines be straight-through passage, and described branch pipe(tube) is divided into many sections by each joint exhaust duct from joint, constituting on each section branch pipe(tube) respectively save exhaust duct and the respective storey pipeline outer wall between indoor, an air inlet port is set respectively, on two sections dividing plates spaced apart from each other between the trunk line of above-mentioned branch pipe(tube) and one side, an exhaust opening is set respectively, on two sections dividing plates spaced apart from each other between the trunk line of above-mentioned branch pipe(tube) and its opposite side, an exhaust opening also is set respectively, above-mentionedly respectively save in the exhaust duct, each section (each joint) is main, the exhaust opening direction difference that is provided with on the dividing plate between the branch pipe(tube) makes adjacent each section branch pipe(tube) be connected with different trunk line respectively.In described branch pipe(tube), with each corresponding two ends that are provided with air inlet port and each section of respective vent ports of joint exhaust duct a closure plate is set respectively, above-mentioned each air inlet port and respective vent ports are enclosed in corresponding each section branch pipe(tube), perhaps in above-mentioned branch pipe(tube) each section corresponding to each joint exhaust duct, at the air inlet port and both ends of respective vent ports (upper end or lower end) that are provided with separately a closure plate is set respectively, described each closure plate is all identical.Enter at above-mentioned each exhaust opening on dividing plate (being the dividing plate between each trunk line and the branch pipe(tube)) wall of corresponding trunk line, a dustpan-shaped exhaust guide pipe is set respectively, each dustpan-shaped exhaust guide pipe is all identical, on the internal face of the pipeline outer wall of the corresponding trunk line adjacent or relative with above-mentioned each dustpan-shaped exhaust guide pipe, a component for variable-pressure is set respectively, this component for variable-pressure be by upper head plate, with basic keeping parallelism of pipeline outer wall or the flat board that is parallel to each other, the trihedral structure that bottom plate constitutes.The bottom plate of described component for variable-pressure and the height of described dull and stereotyped junction are higher than the height of bottom plate and exhaust duct pipeline outer wall touching position.
The component for variable-pressure that constitutes the utility model structure can be a hollow-core construction, also can be for solid construction, its effect is identical.
Because the utility model has adopted two to state the air discharging structure that three pipelines are arranged side by side, and each exhaust ports is provided with dustpan-shaped exhaust guide pipe and corresponding component for variable-pressure, therefore just make that the interior gas of exhaust duct is shunted, thereby reduced the resistance of exhaust duct, helped the smooth discharge of indoor gas air-flow; When space narrow relatively between dustpan-shaped guide pipe of following airflow passes and the component for variable-pressure, the corresponding increasing of flow velocity, the stream pressure that makes dustpan-shaped guide pipe gas outlet is stable negative pressure or zero-pressure, flue gas in the exhaust duct or have the flavor gas can be not indoor by each section branch pipe(tube) each floor of row that refluxes, therefore just make each floor that the phenomenon of smoke blowing, taint of odour can not take place between indoor, the exhaust duct exhaust efficiency also is improved, and has reduced the power consumption of smoke exhaust ventilator or other exhaust plant effectively.
Below in conjunction with drawings and Examples the utility model is further described.
