Description
Technical field
The present invention relates to oily fume exhauster, specifically external wall oil soot exhauster.
Background technology
Along with the development in city and the raising of resident living level, the quality in house and attractive in appearancely more and more paid close attention to by the people.Lampblack absorber is widely used in the cooking apparatus, and it can will cook the oil smoke that produces in the shortest time, directly be discharged into outdoor by oil-smoke expulsion pipes such as PVC.The exhaust outlet of lampblack absorber generally all is located on the exterior wall in house, after the long-time use of lampblack absorber, produce spots such as a large amount of oil stain extensions drips, carbon black around the exterior wall exhaust outlet, both be unfavorable for the cleaning and the replacing of discharge duct mouth, greatly influenced the aesthetic of external wall of house again.Now, most lampblack absorber manufacturers more pay close attention to the function of use and the mist extractor function of lampblack absorber, have ignored oil smoke discharge to outdoor and external wall of house pollution problem that produce.Simultaneously, the builder in house is then more paid close attention to the structure function design in house, has also ignored the pollution problem of oil smoke to exterior wall.So far do not occur effectively to solve the external wall oil soot exhauster of oil smoke to the external wall of house pollution problem for this reason yet.Therefore, how to solve the pollution problem of oil smoke to exterior wall, it is necessary designing a kind of economical and practical external wall oil soot exhauster.
Summary of the invention
The objective of the invention is to propose a kind of pollution problem that solves oil smoke to external wall of house, reduce to greatest extent attached to the oil smoke on the outer surface of wall, the exterior wall in protection house is not subjected to the external wall oil soot exhauster of grunge pollution.
Purpose of the present invention can be achieved through the following technical solutions;
External wall oil soot exhauster comprises three-way pipe, smoke exhaust pipe, long-pending oil pipe, the last pipe of the three-way pipe smoke pipe that runs in, and following pipe connects long-pending oil pipe, and smoke exhaust pipe is for being provided with the pipeline of a bent angle at least, the following pipe flexible connection of long-pending oil pipe and three-way pipe.
Purpose of the present invention can also further realize by following technical measures:
Aforesaid external wall oil soot exhauster, wherein said smoke exhaust pipe links to each other with the pipe of going up of three-way pipe by tube connector, and long-pending oil pipe also links to each other with the following pipe of three-way pipe by tube connector.

The specific embodiment
The present invention mainly considers the emission performance of soot gas from the flowing velocity aspect, by three-way pipe soot gas is derived, by managing the smoke exhaust pipe that is connected soot gas is discharged with going up of three-way pipe, the oil stain that the long-pending oil pipe accumulation that flexibly connects by the following pipe with three-way pipe refluxes, and with its removing.Smoke exhaust pipe of the present invention is to be provided with the pipeline of a bent angle at least, but generally is provided with two bend pipes, and connects by straight tube.The flowing velocity of soot gas when lampblack absorber and fume tube enter three-way pipe probably is 5m/s, because smoke exhaust pipe communicates with outside air, soot gas can be outwards mobile along smoke exhaust pipe.If smoke exhaust pipe is a straight tube, there is not bend, then the flowing velocity of soot gas can not be reduced, and the oil smoke amount of discharging can not obtain reducing.If smoke exhaust pipe is provided with bend, by fluidics as can be known, can obviously reduce the flowing velocity of soot gas.If smoke exhaust pipe is provided with a bend pipe, as calculated, the flowing velocity of soot gas can be reduced to 4.5m/s from original 5m/s, such flowing velocity, though reduced the oil smoke amount of discharging to a certain extent, can make part high-temperature oil smoke condensation of gas attached to pipe fitting inner wall, but, find that the soot gas oil content reduces about 60%～70% by measuring the oil content of the soot gas that compares three-way pipe import department and smoke exhaust pipe exit.If smoke exhaust pipe is provided with two bend pipes, connect by straight tube between two bend pipes, the flowing velocity of soot gas can be reduced to 3m/s from original 5m/s by calculating, such flowing velocity, can reduce the oil smoke amount of discharging in a large number, can make most of high-temperature oil smoke condensation of gas attached to pipe fitting inner wall,, find that the soot gas oil content reduces about 75%～85% by measuring the oil content of the soot gas that compares three-way pipe import department and smoke exhaust pipe exit.If smoke exhaust pipe is provided with three bend pipes, connect by straight tube between each bend pipe, the flowing velocity of soot gas can be reduced to 2m/s from original 5m/s by calculating, such flows through experiment, and discovery speed is too slow, can cause the soot gas of a part to reflux.This shows, smoke exhaust pipe is provided with two bend pipes, the flowing velocity of soot gas can be reduced to optimum value, a large amount of oil smoke amounts that reduce discharging make most of high-temperature oil smoke condensation of gas attached to pipe fitting inner wall.
The bent angle angular range of two bend pipes of smoke exhaust pipe is decided to be 90 degree～135 degree, angle is that the flowing velocity of 90 soot gas when spending is reduced to 3m/s from original 5m/s, increase along with angle, the flowing velocity of soot gas slowly improves, but amplitude is little, when angle is spent greater than 135, the flowing velocity of soot gas has had one significantly to improve, be about 4m/s, such flowing velocity, the oil smoke amount of discharging does not obtain very big reduction, part high-temperature oil smoke gas can not condensation attached to pipe fitting inner wall, by measuring the oil content of the soot gas that compares three-way pipe import department and smoke exhaust pipe exit, find that the soot gas oil content reduces about 50%～60%.Therefore, the bent angle angular range with two bend pipes of smoke exhaust pipe is decided to be 90 degree～135 degree.
The cross-directional length of the bend pipe that links to each other with pipe on the three-way pipe and the ratio range of vertical direction length are
Connect two bend pipes straight tube length smaller or equal to three-way pipe on the cross-directional length of the bend pipe that links to each other of pipe.The length of smoke evacuation vertical direction is enlarged, help the downslide of condensation attached to the extension oil dripping stain of pipe fitting inner wall.If the cross-directional length of the bend pipe that links to each other with pipe on the three-way pipe is identical with vertical direction length or be more or less the same, then condensation is glided not too easily attached to the extension oil dripping stain of pipe fitting inner wall, and a part is hung oil dripping and steeped and accumulate in easily in the horizontal direction pipe.The ratio of cross-directional length and vertical direction length is 1: 2 o'clock, the overwhelming majority is hung the oil dripping stain and can be slided to down in the long-pending oil pipe, and along with reducing of ratio, extension oil dripping stain downslide situation is roughly the same, the flowing velocity of soot gas is also in effective range, but when ratio during less than 1: 5, as arrive at 1: 6 o'clock, the flowing velocity of soot gas is too slow, through measuring, have only 1m/s, such flow velocity makes soot gas produce backflow phenomenon easily.The length of straight tube that connects two bend pipes is also unsuitable oversize, is generally less than the cross-directional length that equals the bend pipe that links to each other with pipe on the three-way pipe, too many extension oil dripping is steeped accumulate in easily in the horizontal direction pipe.
The inwall of smoke exhaust pipe and tube connector is provided with the high polymer composite filter cloth of oil absorbency, can help hanging the downslide of oil dripping stain, and gliding speed can reach 5～10mm/s.
