Technical field
This utility model relates to laboratory equlpment technical field, particularly relates to a kind of ventilated chamber.
Background technology
Ventilated chamber is ingredient important in laboratory ventilation design, the maximum purpose using ventilated chamber is to discharge the toxic and harmful and inflammable produced in experiment, explosive, corrosive substance, prevent the pollutant produced in experiment from spreading to laboratory, it is ensured that the security of the lives and property of operator.
Ventilated chamber is while emission, and the temperature and pressure in ventilated chamber changes therewith, in order to keep ventilated chamber temperature, and pressure balance, need to fill into air while discharging gas.Ventilated chamber benefit wind mode is divided into interior compensating ventilation cabinet and outer compensating ventilation cabinet at present.
Interior air-replenishing type ventilating cabinet, is to be provided above air inlet at ventilated chamber, and air inlet directly communicates with outdoor air.Existing interior air-replenishing type ventilating cabinet, it is mended air quantity and is up to the 60% of exhaust air rate, and once more than 60%, mending wind velocity increases therewith, when the face wind speed mending wind is more than 0.8m/s, occurring vortex in cabinet, harmful gas is piled up, concentrations build-up, exhaust effect is bad, threatens to the safety of operator；Meanwhile, the wind speed excessive harmful gas also easily caused in ventilated chamber in face overflows into indoor, brings actual bodily harm to operator.And, remaining benefit air quantity of 40%, from indoor extraction, also increases the load of room conditioning.
Outer air-replenishing type ventilating cabinet, is to arrange air inlet outside ventilated chamber, the outdoor new wind processed without air-conditioning by air inlet to the operating surface of ventilated chamber above, have impact on the comfortableness that operator operate；Owing to using new wind to discharge again after ventilated chamber operating surface mixes with room conditioning wind, considerably increase the load of air-conditioning.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of ventilated chamber being provided simultaneously with interior benefit wind and outer benefit wind function, and interior benefit wind and outer benefit wind facies are combined, while realizing normal exhaust effect by ventilated chamber of the present utility model, reduce air conditioner load, reduce energy consumption.
To achieve these goals, the technical solution adopted in the utility model: a kind of ventilated chamber, including ventilated chamber cabinet, it is arranged on the air inlet of cabinet top side and is arranged on the exhaust outlet of cabinet top opposite side, described ventilated chamber cabinet front is provided with glass vision panel, described glass vision panel moves up and down relative to cabinet, it is characterized in that, described air inlet lower end is provided with interior benefit wind plenum chamber and wind curtain machine, described interior benefit wind plenum chamber and wind curtain machine be arranged in parallel, described interior benefit wind plenum chamber mends wind for vertical laminar flow, described wind curtain machine is positioned at the inner side of glass vision panel；The outside of described glass vision panel is provided with outer benefit wind plenum chamber, and described outer benefit wind plenum chamber passes through secondary air channel junction chamber exogenous wind, and described outer benefit wind plenum chamber mends wind outside being realized by outer benefit air valve；Described bottom of cabinet bulk is provided with air draught plenum chamber, described air draught plenum chamber is positioned at wind curtain machine and the underface of outer benefit wind plenum chamber region, described air draught plenum chamber is for absorbing the wind that wind curtain machine is discharged with outer benefit wind plenum chamber, described air draught plenum chamber is connected with air draft plenum chamber by exhaust duct, and described air draft plenum chamber is connected with exhaust outlet；Being additionally provided with deflector inside described cabinet, it is inboard that described deflector is positioned at cabinet, and described deflector imports air draft plenum chamber for the wind discharged by interior benefit wind plenum chamber, it is achieved the quick flowing of air in cabinet.
Using such scheme, ventilated chamber air-makeup system includes interior benefit wind and two kinds of forms of outer benefit wind.Interior benefit bellows chamber includes interior benefit wind plenum chamber and mends wind and wind curtain machine and mend at a high speed wind, the wind that interior benefit wind plenum chamber is discharged is vertical laminar flow low velocity wind, it is to avoid wind speed is excessive forms eddy current in cabinet, causes harmful gas to pile up, affects effect of ejecting poison；Wind curtain machine and outer benefit wind plenum chamber are the supplementary mode mending wind, it is provided with air draught plenum chamber immediately below wind curtain machine and outer benefit wind plenum chamber region, while increasing benefit air quantity, effectively absorb the wind that wind curtain machine is discharged, the wind speed of avoiding wind curtain machine to discharge is excessive causes toxic gas excessive, brings actual bodily harm to operator.Cabinet inboard is provided with deflector, after the wind that interior benefit wind plenum chamber is discharged mixes with room air, is imported rapidly air draft plenum chamber by deflector, accelerates air flowing in cabinet, is conducive to the harmful substance produced in experiment to discharge in time.Interior benefit wind and outer benefit wind facies are combined by ventilated chamber of the present utility model, increase benefit air quantity, decrease room air and enter ventilated chamber, reduce the load of air-conditioning while ensureing exhaust effect.
Wherein, being connected with air inlet on the upside of described interior benefit wind plenum chamber, downside is provided with the first netted air outlet.
Wherein, it is provided with the second netted air outlet on the downside of described outer benefit wind plenum chamber.
Wherein, it is provided with netted inlet scoop on the upside of described air draught plenum chamber.
Compared with prior art, the beneficial effect that this utility model realizes: interior benefit wind and outer benefit wind facies are combined by ventilated chamber of the present utility model, increase benefit air quantity, reduces room air and enters ventilated chamber, reduce the load bringing air-conditioning.
Accompanying drawing explanation
This utility model is further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of ventilated chamber of the present utility model.
Detailed description of the invention
