Abstract
The utility model relates to a shared gas exhausting pipe with a blower fan, which is suitable for shared gas exhausting systems of multi-storey buildings, middle buildings, and high rise buildings and is composed of a pipe and a blower fan. The blower fan is fixed on the pipe wall; a gas outlet of the blower fan is arranged in the pipe; the gas outlet of the blower fan faces the upper part of the pipe; a gas inlet of the blower fan covers the outer part of the pipe; the gas inlet utilizes negative pressure to pump gas. As a result, the pipe can have a single gas channel or double gas channels, and the blower fan can be a centrifugal blower fan, an axial blower fan, or a mixed-flow blower fan. The utility model has the advantages of small indoor noise of gas exhaust, small gas exhausting resistance, high gas exhausting efficiency, low cost of gas exhaust systems, etc.
Description
The utility model belongs to building, particularly the pipeline of multilayer and semi-high-rise housing kitchen, toilet shared ventilation system.
At present, the live gas extraction system of building of people adopts single function common conduit usually.Each resident family by smoke exhaust (or exhaust fan) with connect airduct oil flue waste gas entered common conduit.Owing to is the malleation exhaust, cause that exhaust resistance is big, contaminant removal effectiveness is low, system cost is high, conduit volume is big, room noise is big etc. in the common conduit outside.
The purpose of this utility model is the shortcoming that overcomes prior art, and the common exhaust duct of the band blower fan that a kind of indoor exhaust noise is little, exhaust resistance is little, exhaust efficiency is high, the gas extraction system cost is low is provided.
The utility model is made up of pipeline and blower fan, and blower fan is fixed on the duct wall, and the gas outlet of blower fan places in the pipeline, and the blower fan gas outlet is towards pipeline top, and fan air inlet places outside the pipeline, and air inlet is a negative pressure ventilation.
Fan air inlet of the present utility model is a negative pressure ventilation, and direct and resident family's exhaust duct coupling joins.Compared with prior art, it is little to have an indoor exhaust noise, and it is convenient to clean, and exhaust resistance is little, improves exhaust efficiency, thereby reduces advantage such as gas extraction system cost.
The utlity model has than extensive applicability.Its pipeline can be single air flue, double air passage.The blower fan that adopts can be centrifugal blower, axial flow blower or flow-mixing blower fan.
The utility model is further described as follows below in conjunction with description of drawings:
