Abstract
The utility model relates to a collecting exhausting pipe for residential building. The vertical thin-wall pipe is provided with a guide member which divides a flue into a main flue and an aided flue. The upper part of the pipe is provided with a gas inlet which is communicated with the aided flue, and the gas inlet is connected with a non-return valve and a removing and exhausting cooker hood. The made collecting exhausting system for residential building better solves the problems of exhausting the fume in the kitchens of the residential building with multiple floors and the high residential building, and exhausting the waste gas of other places, such as toilets, and bathrooms.
Description
The utility model relates to a kind of vertical duct of building, particularly the concentrated stack of housing construction fume centralized exhaust system.
The present increasingly extensive range hood that uses has been created condition as the cooking fume-collecting in kitchen, but the discharging of oil smoke gas, does not particularly obtain so far at the concentrated emission problem of the soot gas of modern dwelling building and properly settles.As a result, kitchen oil flue gas or directly discharge to outdoor corridor, or broken wall is to the open air discharge causes the environment pollution around the layer of living, crime of injuries by explosive substances to buildings and goods therein attractive in appearance.For this reason, housing construction fume centralized exhaust system is all being studied by Jing'an District, Shanghai City housing construction engineering company, Huifeng Corrosion Resistance Pump Co., Shanghai etc., and this system comprises range hood, check (non-return) valve, concentrates stack, four parts of roof air outlet.
The purpose of this utility model provides a kind of concentrated stack of housing construction fume centralized exhaust system.
Task of the present utility model is finished like this.Concentrating stack is vertical the setting, pipe range is identical with building standard floor height, the tube and tube vertical butt joint, the external roof of top stack air outlet, respectively there is ways the inherent upper and lower part of stack, and last ways will be managed the internal upper part space and is separated into flue collector and auxillary flue, after the oil smoke gas that discharge in this kitchen, room enters the following guide frame of the concentrated stack in room, upper strata along last auxillary flue, enter the upper strata flue collector, discharge outdoor at last.Be communicated with last auxillary flue on stack top and have air inlet port, this air inlet port is connected with check (non-return) valve one end, and the other end of check (non-return) valve then is connected with the stack of range hood.
Fig. 1 concentrates the front view of one of stack for the utility model
Fig. 2 concentrates two front view of stack for the utility model
Fig. 3 is the A-A sectional view of Fig. 1
Fig. 4 is the B-B sectional view of Fig. 2
Now in conjunction with the accompanying drawings the utility model embodiment is further described.Last ways (1) will be managed the internal upper part flue and will be separated into flue collector (2) and auxillary flue (3).Last ways (1) is plate shaped, and dull and stereotyped bottom is bending or garden bowing, and is connected with body (7) sidewall.At the bottom of pipe ways, plate ways (4) or triangular cross-section type ways (5) are arranged.Air inlet port (6) is arranged on the top of pipe, and air inlet port (6) is connected with check (non-return) valve one end, and the other end of check (non-return) valve then is connected with the extract duct of range hood.
Concentrated stack is the thin wall type structure, adopt the inclined to one side alkali-free glass fibre grid cloth of chlorination one-shot forming in the cement mortar, 10～15 millimeters of wall thickness, pipe range is identical with the standard floor height, be 2.8 meters, it is different and different that the stack cross dimensions is looked the building floor height, for example: for the 19th～24 floor height buildings, the pipe section size may be selected to be 250 * 550 millimeters, and major and minor flue sectional area is respectively 0.0966,0.0230 square metre.The utility model concentrates stack also can select other organic or inorganic material manufacturings for use.As gypsum, perlite, metal, plastics etc., the section configuration of pipe can be rectangular, other shapes such as also can be square, the garden is tubular.
The supporting composition housing construction of the utility model fume centralized exhaust system, effect with good collection and discharging kitchen oil flue gas and other place such as lavatory, washroom life waste gas, prevent that effectively flue gas from flowing backwards, collaborating mutually, help to improve dwelling environment, solved fume emission problem high-rise, multistoried housing construction preferably.
