Description

The pressure variable exhausting channel structure of high-rise building
The present invention 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).
China utility model patent CN87210675U has announced a kind of pressure variable exhausting channel structure, it is made up of main air duct, variable-pressure plate, guide pipe, branch air duct, variable-pressure plate is fixed on the main air duct wall, guide pipe is loaded on the branch air duct place, the variable-pressure plate upper surface is higher than guide pipe outlet present position, and variable-pressure plate is made of upper surface and inclined plane.Because to constitute section by upper surface and inclined plane is leg-of-mutton parts to variable-pressure plate, the whole inclined plane of variable-pressure plate is a gas-flow resistance face, and is bigger to the resistance area of air-flow, so its shortcoming is big to gas-flow resistance, is unfavorable for the flue gas smooth discharge.
Task of the present invention is, a kind of resistance that effectively reduces variable-pressure plate to air-flow is provided, and helps the pressure variable exhausting channel structure of the high-rise building of fume emission.
In order to finish above-mentioned task, the solution that the present invention takes is, it comprises trunk line, branch pipe(tube) and air inlet port, trunk line and branch pipe(tube) are arranged side by side, 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, constitute 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.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, be characterized in, 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.Above-mentioned component for variable-pressure is the trihedral structure that constitutes by upper head plate, with the basic keeping parallelism of pipeline outer wall or the flat board that is parallel to each other, bottom plate.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 structure of the present invention can be a hollow-core construction, also can be for solid construction, its effect is identical.
Because the air discharging structure that the present invention has adopted above-mentioned three pipelines to be 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, component for variable-pressure only is its lower surface to the direct resistance area of air-flow, resistance area reduces, 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 to have flavor gas can not be back to each floor by each section branch pipe(tube) indoor, 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.
The present invention is further illustrated below in conjunction with drawings and Examples.
