Abstract
The invention provides a green ventilation cabinet for a laboratory, which comprises an upper cabinet body and a lower cabinet body, wherein the upper cabinet body and the lower cabinet body are connected into a whole through side plates, a work table is formed between the upper cabinet body and the lower cabinet body, a ventilation passage connected with a centrifugal fan is arranged in the upper cabinet body, and an outlet of the ventilation passage is provided with a negative pressure type exhaust opening extending out from the top end of the upper cabinet body. The green ventilation cabinet is characterized in that an air filter is arranged in the upper cabinet body and is positioned at the front end part of the ventilation passage in the exhaust direction of negative pressure air. The green ventilation cabinet provided by the invention has the advantages that toxic or harmful gas generated or volatilized in the experiment process can be totally sucked to the exhaust opening to be exhausted out through the negative pressure type air extracted from bottom to top, through the arrangement of the air filter arranged at the front end of the ventilation passage, the gas can be effectively adsorbed and filtered before being exhausted from the exhaust opening, and the gas exhausted from the exhaust opening is enabled to be clean and harmless. After the green ventilation cabinet is adopted in the laboratory, the overflowing of harmful chemical gas can be avoided, the outdoor environment outside the laboratory can be protected, and a gas self purification function is realized.
Description
Technical field
The present invention relates to a kind of Novel fume chamber, relate in particular to a kind of green vent cabinet for chemical laboratory.
Background technology
In the chemical laboratory of big-and-middle universities and colleges and R&D institution etc., generally all need to be equipped with vent cabinet.The Main Function of vent cabinet is that poisonous, the pernicious gas that in chemical laboratory, produce are expelled to outdoor.At present, common vent cabinet is mainly made up of the upper cabinet and the lower cabinet body that connect as one by side plate, space between the two forms workbench, and upper cabinet connects ventilating duct, and poisonous, the pernicious gas that in experimentation, on workbench, produce are extracted out from ventilating duct by blower fan.The problem that vent cabinet exists is at present: poisonous, pernicious gas is just disposed to outdoor by ventilation shaft, could not process it online, can pollute laboratory external environment.
Summary of the invention
In order to solve the deficiency in background technology, the object of the invention is to overcome the defect of background technology, provide a kind of laboratory green vent cabinet, after use, avoid the excessive of chemical gas, protect the environment outside laboratory.
For achieving the above object, the technical solution used in the present invention is: the green vent cabinet in a kind of laboratory, comprise the upper cabinet and the lower cabinet body that connect as one by side plate, between described upper cabinet and lower cabinet body, form workbench, in described upper cabinet, be provided with the ventilating duct being connected with centrifugal blower, the outlet of described ventilating duct is provided with the suction type exhaust outlet that stretches out described upper cabinet top, it is characterized in that: the front end place that is positioned at described ventilating duct along the discharge direction of suction type wind in described upper cabinet is provided with air cleaner.
In a preferred embodiment of the present invention, further comprise in described upper cabinet, be provided with one be communicated with described ventilating duct push away groove, described in what described air cleaner can push-and-pull be arranged on, push away in groove.
In a preferred embodiment of the present invention, further comprise that described air cleaner is the block active carbon filter of layer.
In a preferred embodiment of the present invention, further comprise that the bottom surface of described upper cabinet is parallel with described workbench, and the bottom surface of described upper cabinet from space cover described workbench directly over.
In a preferred embodiment of the present invention, further comprise that the described side plate of described workbench top is provided with deflector.
In a preferred embodiment of the present invention, further comprise that roller is equipped with in the bottom of described lower cabinet body.
Usefulness of the present invention is: the green vent cabinet in a kind of laboratory of the present invention, the suction type wind of taking out is from the bottom up discharged poisonous, the whole sucking-offs of pernicious gas to the exhaust outlet that in experimentation, produce or volatilize, by air cleaner being set at ventilating duct front end, make gas can effectively be adsorbed and filter out from exhaust outlet is discharged, guarantee that the gas of discharging is clean harmless from exhaust outlet.After laboratory using vent cabinet of the present invention, can avoid the excessive of harmful chemical gas, can the outdoor environment in Protection chamber, possess the function of gas auto purification.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the stereogram of the preferred embodiment of the present invention;
Fig. 2 is the front view of the preferred embodiment of the present invention.
In figure: 2, side plate, 4, upper cabinet, 6, lower cabinet body, 8, workbench, 9, ventilating duct, 10, exhaust outlet, 12, air cleaner, 14, push away groove, 16, deflector, 18, roller.
The specific embodiment
In order to make those skilled in the art person understand better the present invention program, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1-2, the green vent cabinet in a kind of laboratory, comprise the upper cabinet 4 and the lower cabinet body 6 that connect as one by side plate 2, between upper cabinet 4 and lower cabinet body 6, form workbench 8, in upper cabinet 4, be provided with the ventilating duct 9 being connected with centrifugal blower, the outlet of ventilating duct 9 is provided with stretches out the outside suction type exhaust outlet 10 in cabinet 4 tops, and the front end place that the interior discharge direction along suction type wind of described upper cabinet 4 is positioned at ventilating duct 9 is also provided with air cleaner 12.In experimentation, the gas producing from workbench 8 is discharged under the suction type wind suction of taking out from the bottom up from exhaust outlet 10, at ventilating duct 9 front ends, air cleaner 12 is set, make gas can effectively be adsorbed and filter out from exhaust outlet 10 is discharged, guarantee that the gas of discharging is clean harmless from exhaust outlet 10.After laboratory using vent cabinet of the present invention, can avoid the excessive of harmful chemical gas, can the outdoor environment in Protection chamber, possess the function of gas auto purification.
Concrete, upper cabinet 4 interior arrange one be communicated with ventilating duct 9 push away groove 14, air cleaner 12 can being arranged on of push-and-pull push away in groove 14, is similar to the plug-type project organization of drawer, and air cleaner 12 displacements are facilitated.
The preferred air cleaner 12 of the present invention is the block active carbon filter of layer, the composition principal component of active carbon filter is active carbon, and adsorptivity is strong, and cost is low, the gas of discharging in the chemical laboratory for educational institutions such as big-and-middle universities and colleges, scientific research institutions, the adsorption capacity of active carbon is enough.
