Abstract
The utility model involves an exhaust passage for preventing smoke-channeling, and includes an exhaust passage, a transformer panel and a curved horn. The utility model is characterized in that: the air-let of the exhaust passage is connected with the curved horn; the curved horn is arranged on the inner side of the exhaust passage; the transformer panel is arranged on the opposite of the gas outlet. The advantages of the utility model lie in that: the siphonage is obvious within the exhaust passage; the utility model has a good smoke-channeling and anti-intrusion ability, and has a large displacement.
Description
Technical field
The utility model relates to the exhaust duct in a kind of dwelling house fume emission, particularly anti-channeling cigarette exhaust duct.
Background technology
Exhaust duct in the present dwelling house fume emission, majority is that exhaust duct is a blank pipe, indoor flue gas enters from the exhaust duct air inlet port, directly inject in the exhaust duct, the airflow direction in its direction and the exhaust duct is orthogonal, the bounce-back of bump exhaust duct, produce eddy current, the air curtain that forms hinders the indoor exhaust air discharge of floor down, and flue gas pours in down a chimney in the inlet chamber easily.
The utility model content
The utility model purpose provides a kind of anti-channeling cigarette exhaust duct, requires capacity big, and anti-channeling cigarette ability is strong.
The technical solution of the utility model is a kind of anti-channeling cigarette exhaust duct of design, comprise that exhaust duct, variable-pressure plate and ox horn are curved, it is characterized in that: variable-pressure plate is located at the exhaust duct upper end, the curved volt of ox horn is in the exhaust duct inboard, its big mouthful and air inlet port communication are shunk gradually, and the gas outlet communicates with exhaust duct, the cross-sectional sizes of the variable-pressure plate symmetrical with it changes according to the capacity needs of each floor of dwelling house.
The utility model has the advantages that siphonage is obvious, the anti-channeling cigarette is anti-to pour in down a chimney ability Strong, and capacity is big.
Description of drawings
Accompanying drawing is a structural profile schematic diagram of the present utility model.
Digital being expressed as respectively in the accompanying drawing: exhaust duct 1, air inlet port 2 ox horns are curved 3, gas outlet 4, variable-pressure plate 5.
The specific embodiment
The specific embodiment of the present utility model is to equate with the residential building number of plies, and exhaust duct 1 vertical put contour with floor has one of variable-pressure plate 5 to dock mutually up, forms dwelling house fume centralized exhaust system; When the indoor fan startup, flue gas enters from air inlet port 2, by ox horn curved 3, enter in the exhaust duct 1 by gas outlet 4, its airflow direction is consistent with airflow direction in the exhaust duct, and in addition, curved 3 imports of ox horn are big, runner upwards shrinks gradually, gas outlet 4 cross section minimums, the flue gas that passes through are through herein, and flow velocity increases, the pressure minimum can not scurried cigarette, be poured in down a chimney with air curtain and form; Because exhaust duct 1 upper end is provided with variable-pressure plate 5 and curved 3 gas outlets 4 of ox horn, its cross section minimum, when the ascending air in the exhaust duct 1 passed through herein, runner diminished suddenly, the gas flow rate maximum, the pressure minimum, ox horn is bent 3 exits, is in low-pressure area, the pressure minimum; The utility model has the advantages that: the runner siphonage in the ox horn curved 3 in each floor exhaust duct 1 is obvious, and anti-channeling cigarette and the anti-ability of pouring in down a chimney are strong, and the capacity of exhaust duct 1 is big, and floor space is little.
