Abstract

Disclosed is a flue that discharges gas together for the houses, comprising flues used in each storey. The utility model is characterized in that the side walls of the flues from the second storey to the top storey are provided with exhaust ports; clapboards are arranged on the positions corresponding to the exhaust ports; the other side walls facing the above side walls are provided with exhaust holes; other clapboards are arranged on the positions corresponding to the exhaust holes; the lower end of the clapboard is kinked and is fixedly connected with the side wall of the flue; the approximate upper end of the clapboard is kinked; the upper end of the clapboard vertically extends to the beginning of the clapboard of the flue in the prior storey; and the flue arranged on the most bottom storey is provided with an air inlet. With such structure, as the two clapboards separate the exhaust ports from the exhaust holes, the gas can be effectively prevented from mixing up. The air inlet provides power for the gas inside the flue to be discharged upward, which greatly reduces the residence time of the gas inside the flue, and thus the gas is fast discharged to the high altitude.

Description

The flue that a kind of dwelling house discharges with fume centralized

Technical field

The utility model relates to a kind of flue.

Background technology

China's utility model patent discloses a kind of name and has been called: for the flue (patent No.: 01207873.5, notification number: CN2467662Y) of concentrating discharging behind the dwelling house flue gas elder generation shunting, this flue uses in each layer of residential building, have two holes up and down on the flue, be smoke vent opening above, be steam vent below, the smoke blowing phenomenon can take place in two holes up and down, be unfavorable for oil smoke and waste gas in the abundant drain chamber, in addition in flue, corresponding steam vent place down only installs a semiclapboard additional, still have a spot of oil smoke string to steam vent, do not stop the smoke blowing phenomenon fully.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of flue that prevents smoke vent opening, the mutual smoke blowing of steam vent.

The utility model is by the following technical solutions: a kind of dwelling house is with the flue of fume centralized discharging, be included in the flue of each layer of residential building use, it is characterized in that: have smoke vent opening on the sidewall of the flue that the second layer to top layer uses, to being provided with dividing plate in the smoke vent opening place, on another sidewall that sidewall is relative therewith, have steam vent, to being provided with another dividing plate in the steam vent place, described dividing plate lower end is bending, and with the flue sidewall Joint, dividing plate is bending near upper end, and the upper end of dividing plate extends vertically up to the section start of last layer buffler.Adopt such structure, because two dividing plates are isolated with smoke vent opening and steam vent, can prevent effectively that flue gas from going here and there phenomenon mutually, the upper end of dividing plate extends vertically up to the section start of last layer dividing plate in addition, in flue, formed the long sub-flue in path, accelerated the speed that cigarette (gas) rises, stifled exhausted smoke backflow.

The utility model also can adopt following further technical scheme:

Be positioned on the flue of the bottom and have air intake, adopt such structure, give in the flue flue gas upwards discharging power is provided, significantly reduced the holdup time of flue gas in flue, make the rapid high altitude discharge of flue gas.

Description of drawings Fig. 1 is a sectional view of the present utility model.

The specific embodiment

As shown in the figure, flue 1 uses in each floor of residential building, directly butt joint connection between each layer flue, top layer butt joint air chimney 2, have smoke vent opening 3 on one sidewall of the flue 1 that the second layer to top layer uses, to being provided with dividing plate 4 in the smoke vent opening place, on another sidewall that sidewall is relative therewith, have steam vent 5, to being provided with another dividing plate 4 in steam vent 5 places, described dividing plate 4 lower ends are bending, and with the flue sidewall Joint, dividing plate 4 is bending near upper end, the upper end of dividing plate 4 extends vertically up to the section start of last layer buffler.Exhaust fan can be installed by steam vent 5 places, and check (non-return) valve can be installed by smoke vent opening 3 places.

Be positioned on the flue 1 of the bottom and have air intake 6, air intake 6 can be arbitrary shapes such as square, circle.

Claims (2)

1, the flue that a kind of dwelling house discharges with fume centralized, be included in the flue (1) of each layer of residential building use, it is characterized in that: have smoke vent opening (3) on the sidewall of the flue (1) that the second layer to top layer uses, to locating to be provided with dividing plate (4) by smoke vent opening (3), on another sidewall that sidewall is relative therewith, have steam vent (5), to locating to be provided with another dividing plate (4) by steam vent (5), described dividing plate (4) lower end is bending, and with flue (1) sidewall Joint, dividing plate (4) is bending near upper end, and the upper end of dividing plate (4) extends vertically up to the section start of last layer flue (1) dividing plate.

2, a kind of dwelling house as claimed in claim 1 is characterized in that with the flue of fume centralized discharging: be positioned on the flue (1) of the bottom and have air intake (6).
