Description
Technical field
The utility model belongs to use for laboratory ventilation equipment technical field, more particularly to a kind of ventilation hoods for laboratories.
Background technology
Laboratory ventilation equipment is an indispensable part in lab design.In order that laboratory work people
Member does not suck or swallowed the chemical substance that some are poisonous, can causing a disease or toxicity is not clear and should have in organism, laboratory good
Good ventilation.To prevent some steams, gas and the absorption of particulate, polluter must use vent cabinet, ventilator cowling or local ventilation
Method remove.Vent cabinet is a kind of intermittent local ventilation the most frequently used in laboratory, and species is various, because its structure is different,
The condition used is different, and its exhaust effect also differs.
During vent cabinet carries out chemistry experiment operating, various volatile liquid fluxs and examination are often used
Agent, these volatile liquid fluxs and reagent can be discharged to outdoor with the ventilating system of vent cabinet, air be caused larger
Pollution.And existing vent cabinet can not carry out liquefaction recovery to these volatile liquid fluxs and reagent, it is therefore desirable to grind
Hair designs a kind of ventilation hoods for laboratories that be able to can be reclaimed to volatile reagent, reduces pollution.
Utility model content
The utility model for solve technical problem present in known technology provide it is a kind of it is simple in construction, reasonable in design,
The ventilation hoods for laboratories that volatile reagent can be reclaimed.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：A kind of laboratory

Control panel electrically connects；The front end face of the upper wardrobe body offers experimental implementation window, be provided with experimental implementation window can on
The glass sash window of lower movement, the lower edge of glass sash window are provided with the push-and-pull sash handle of bending type；The top of the upper wardrobe body
Portion offers exhaust outlet, and the upper end of the exhaust outlet is connected with exhaust duct, is provided with exhaust blower in exhaust duct, exhaust blower with it is described
Controller electrically connects；The lower end of the exhaust outlet is detachably provided with taper gas skirt, and the lower edge of gas skirt bends inwards
Form the collecting tank of annular.
The advantages of the utility model and good effect are：The lower end of the utility model exhaust outlet is detachably provided with taper collection
Gas hood, the lower edge of gas skirt bend inwards to be formed annular collecting tank, volatile reagent enter exhaust outlet during,
Liquefy in the condensed on inner walls of taper gas skirt, flowed into along the inwall of taper gas skirt in the collecting tank of annular；The collection of annular
After a certain amount of chemical reagent and solvent are collected into liquid bath, taper gas skirt can be disassembled the chemical reagent of collection and
Solvent is focused on, so as to reduce the pollution to environment.
Preferably：Temperature sensor is additionally provided with inside the upper wardrobe body, temperature sensor electrically connects with the controller.
Preferably：Deflector is provided with backboard inside the upper wardrobe body.
