2, the ventilation in present most office premisess, hotel, restaurant relies on air-conditioning fully, can not or be difficult to open the window.Advance new wind though require air-conditioning must possess fresh wind port, intrinsic indoor exhaust air still can't be avoided the harm of indoor exhaust air to human health if can not get appropriate discharging, and the appearance of so-called " air conditioner disease " is proved exactly.
3, the open type building of large-scale public place such as sports palace, arenas, dining room and production department and so on has all designed " ventilation mouth " (dividing nature exhaust and mechanical assistance exhaust two classes) in the top of space of spaciousness." ventilation mouth " product that existing market provides, complex structure, cost height, Chinese People's Anti-Japanese Military and Political College's interference in air flow scarce capacity is not stopped the down draught phenomenon;
4, useless (poison) gas that experiment produces in the laboratory fume hoods such as metallurgy, chemistry is established blast fan in the roofing discharge tube, adopt the mode of direct pump drainage to enter atmosphere at roofing.This aeration technology is extensively promoted the use of for many years, but practical effect reflects that it has deficiency.At first, design can not configuration energy be enough to overcome the high-power blast fan of sporadic down current, so (poison) gas that gives up in the pipeline pours in down a chimney indoor sometimes.Next, useless (poison) gas directly pollutes, corroding is its blast fan that adds energy.Moreover roofing is the drum Ventilator Room specially, certainly will strengthen investment.
5, existing home-use various smoke exhaust ventilators, the culinary mist extractor in dining room system etc., oil smoke directly pollutes fan, motor, and lampblack dirty is extremely difficult to be cleaned, and leaves the unsafe hidden danger of electricity consumption;
6, nation-building portion key popularized project: the shared exhaust duct patented technology of the house kitchen pressure swing type (patent No.: ZL00266602.2), each layer of residential building lampblack absorber floss hole is tapped into common conduit, make the kitchen fume of every family converge the back and enter atmosphere, avoided metope to be polluted from roofing.The oil smoke trend of this technology has been represented the direction of indoor exhaust air draining technology development, but the scope of application is little, only limits to the processing to oil smoke beyond the household kitchen smoke exhaust ventilator floss hole.This technology adopts main, branch pipe(tube) structure, and key position is provided with special variable-pressure plate, guide pipe in pipeline, can prevent the cross pollution after each layer oil smoke enters pipeline smoothly usually.But analyze from structure, resist the hardware assurance that sudden drop air-flow is invaded owing to lack, the just unavoidable oil smoke that takes place in the shared exhaust duct pours in down a chimney, and the taint of odour of each interlayer is inevitable at that time.
Three, summary of the invention:
1, the utility model is a kind of device that discharges the building indoor exhaust air of design, and has set up the scientific theory that meets the modern architecture aeration technology for it, is used for instructing the design to the indoor exhaust air tapping equipment under the various states of building.Reach the unidirectional discharging of waste gas, do not pour in down a chimney, do not reflux, do not collaborate or cross pollution, directly do not pollute, etching apparatus, safe and reliable purpose.
2, Fig. 1 is that (generally being applicable to the composition structure chart of tier building indoor exhaust air tapping equipment) always schemed in composition structural representation of the present utility model.This device comprises: pneumatic device 1, motor 2, fan 3, outer cover 4, first connector 5, rectification body 6, second connector 7, waste gas outlet 8, exhaust piping 9, electric wire 10, power switch 11.Pneumatic device 1 is installed in device top and motor 2 and fan 3 and is in the same rotating shaft; Outer cover 4 usefulness first connector 5 is connected with rectification body 6 and is fixing, and outer cover is connected with waste gas outlet 8 by second connector 7 and is fixing simultaneously; Exhaust piping 9 is arranged in the building masonry wall, the waste gas outlet 8 that connects suitable for reading of exhaust piping 9, and end opening leads directly to the indoor of building; Power switch 11 is arranged on indoor, by the rotation of electric wire 10 control motor 2 and fan 3; Pneumatic device 1 is when no power, rotates by wind drive fan 3.
This device is a utilization gas-kinetic theory basic principle, makes device play a part to form a connecting link in the toxic emission process, becomes the key of indoor exhaust air discharging success or not, and it plays " energy converter " effect in the indoor exhaust air discharge process.The device self-energy derives from electric energy (or wind energy), and fan is converted to the interior all-round h of device with electric energy (or wind energy), and then the hydrostatic head increment in the bascule, kinetic head increment, position pressure head increment and various loss in head.
Air produces motion in the device after all-round h drives, through the effect of rectification body, h mainly is converted to the kinetic energy of air stream in the device except that overcoming resistance, speed V maximum when air being flow to reach the exhaust piping outlet, pressure P is then minimum, forms the low pressure endless belt around waste gas outlet.Be full of the indoor exhaust air molecule of pipeline, the as easy as rolling off a log low pressure endless belt that enters obtains enough kinetic energy at the waste gas outlet place, diffuses into swiftly flowing air stream rapidly, flows together with air stream.At this moment, the waste gas in the pipeline is according to the continuity equation of incompressible gas:
V
2A＝V
1A
Annotate: V
2-waste gas outlet flow velocity; V
1-exhaust gas entrance flow velocity; The A-pipeline section is long-pending; Indoor exhaust air just enters this device continuously from entrance, diffuses into swiftly flowing air stream then.Mixed air-flow slows down gradually in flow process subsequently and boosts, and enters atmosphere at last.
If indoor exhaust air is limited to oil smoke in the kitchen oil petticoat pipe, suitably strengthen all-round h again, be used to overcome the pipeline on-way resistance, just can be used for oil smoke directly is discharged into roofing.
