Description
Technical field
The utility model relates to vent cabinet field, is specially a kind of lower return air vent cabinet.
Background technology
The toxic emission (local exhaust) of vent cabinet for laboratory is typically provided with in laboratory, vent cabinet can by the poisonous and harmful produced in experimentation, have peculiar smell, flammable explosive gas or dust, corrosive gas and moisture etc. to discharge laboratory, play the function of forced ventilating.Existing vent cabinet is typically designed to air-exhaust type, and air-flow passes through bottom adjustable door and enters in vent cabinet between table top (front cross member), and the gas skirt being advanced into vent cabinet top on upper, middle and lower exhaust outlet is direct imports exhaust duct.
When exhaust air rate and surface wind speed constant (according to corresponding standard), this structure is applicable to discharge the waste gas that proportion is comparatively light, humidity is lower.Comparatively large for discharge proportion, the waste gas poor effect that humidity is higher, is in particular in following two aspects: 1, toxic emission is slow, can not drain timely and effectively when producing relatively large heavy gas at short notice, and is accumulated in vent cabinet or overflows outside vent cabinet; 2, when the waste gas that discharge humidity is higher, due to the effect of the temperature difference, easily form condensate liquid at vent cabinet inwall, final drippage and refluence are on table top, and this kind of phenomenon is obvious at deflector, backboard, top board and exhaust hood place.It not only can affect healthy, service life that also can shorten vent cabinet and system equipment of staff, and the waste gas of directly discharge also can cause atmosphere pollution.
Utility model content
Producing to fully meet, testing emissions requirements; solve heavily gas; moisture; and the emission problem of dust; reach and effectively absorb organic exhaust gas and dust, improve the security that vent cabinet uses, extend the service life of vent cabinet and exhaust system; more effective protection of the environment, the utility model provides a kind of lower return air vent cabinet.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of lower return air vent cabinet, be made up of cabinet and Mead-Bauer recovery system two parts, Mead-Bauer recovery system is positioned at the downside of operating desk, and cabinet is provided with the operating table surface be connected with front crosspiece; Described operating table surface is bottom-up is provided with chin spoiler, baffle upper plate, backboard, left side plate, top board, illuminations, gas skirt, and is provided with exhaust outlet between chin spoiler and baffle upper plate; Air-return duct is provided with between described baffle upper plate and backboard; Devil liquor recovery groove is provided with between described chin spoiler and backboard; The side of described top board is provided with adjustable door and upper cover plate; Described Mead-Bauer recovery system is made up of waste liquor recycling bin and the discharging of waste liquid pipe being connected to devil liquor recovery trench bottom; The side of described waste liquor recycling bin is provided with mobile base cabinet.
As preferably, described vent cabinet adopts downward blowing, air-flow is by entering in vent cabinet with top board top air holes bottom adjustable door and between front cross member, exhaust outlet between baffle upper plate and chin spoiler, enter air-return duct after coming downwards to devil liquor recovery groove, import exhaust duct by the gas skirt entering vent cabinet top after organic exhaust gas absorber or dust filtering device; If air-flow forms condensate liquid under the effect of natural temperature differential on baffle upper plate and air-return duct inwall, they will be back in devil liquor recovery groove, be imported and be stored in waste liquor recycling bin by discharging of waste liquid pipe.
As preferably, can select in the air-return duct between described baffle upper plate and backboard machine Waste gas absorbing device is installed or just imitate, medium effeciency filter.
As preferably, can select between described top board and gas skirt machine Waste gas absorbing device is installed or just imitate, medium effeciency filter.
As preferably, described vent cabinet each position material can select various metal and nonmetallic materials and various synthetic material according to different experimental situations, while meeting instructions for use, reduce equipment cost.
The utility model uses downward blowing, can effective combustion gas, can prevent from again forming returned acid above operating desk, effectively can also absorb organic exhaust gas, scientific and reasonable design adds suitable material, can not only meet various requirement of experiment, the service life of blower fan, airduct can also be extended, cost-saving, be a superior performance, the experimental laboratory air exhausting equipment that practicality is superpower.
