Description
Technical field
The utility model is related to laboratory ventilation apparatus field, specially a kind of novel draught cupboard to dehumidify.
Background technology
Draught cupboard, also known as fuming cupboard are or, be laboratory, a kind of especially large scale equipment of chemical laboratory.Purposes is to reduce
Contact of the experimenter with pernicious gas.Isolation then needs to use glove box completely.Draught cupboard, which is protection staff, prevents toxic chemical
The primary barrier of flue gas harm.It can be as important safe backuup equipment, as in chemical experiment procedure failure, chemical cigarette
Pernicious gas is effectively discharged in mist, dust and toxic gas when generating, protect staff and laboratory environment.Gaschromatographic mass spectrometry
Combined instrument can be detected analysis to pesticide residue, food additives, escaping gas etc., and purposes is very extensive.But have
Some not volatile substances such as amino acids, carbohydrate, if be without derivatization treatment cannot enough GC-MS examine
Survey analysis.The most commonly used is silanization treatments for derivatization treatment, but Silylation reagent is very sensitive to moisture, wet
It spends height and may result in derivatization failure.Current draught cupboard typically just can guarantee discharge toxic gas in time, ensure experiment
The safety of personnel, but the humidity needed for experiment condition cannot be guaranteed.
Utility model content
The problem of for background technology, the utility model provide a kind of novel draught cupboard to dehumidify, it is intended to
One kind is provided and both can guarantee air humidity necessary to experiment, it is also desirable to the draught cupboard that toxic gas can be discharged in time.
To achieve the above object, the utility model provides the following technical solutions：A kind of novel draught cupboard to dehumidify, including
Bookcase body, ventilation opening, the ventilation opening are located at the top of the bookcase body, are provided with wind-collecting cover at ventilation opening, the wind-collecting cover passes through
Conduit is connected with exhaust blower, and filter is provided in the conduit, and the avris of the bookcase body is provided with liftable glass baffle plate,
It is provided with Intelligent humidometer on the glass baffle plate, dehumidifier, lighting system are additionally provided at the top of the bookcase body.
As a kind of preferred technical solution of the utility model, the wind-collecting cover is internally provided with filter screen.
As a kind of preferred technical solution of the utility model, the wind-collecting cover is dismountable.
As a kind of preferred technical solution of the utility model, the catheter interior has depended on multi-layer porous sorbing material.
Compared with prior art, the utility model has the beneficial effects that：The utility model utilization is filtered for multiple times can be as possible
Filter out the pernicious gas being discharged in air, using dehumidifier, ensure the air humidity in show window, do not influence experimental result,
It not only can guarantee in this way and do not pollute air, ensure the humidity of draught cupboard, improve the accuracy of experimental result.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
In figure：1- bookcase bodies；2- wind-collecting covers；3- filter screens；4- ventilation openings；5- conduits；6- exhaust blowers；7- dehumidifiers；8- shines
Bright system；9- glass baffle plates.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment：
Referring to Fig. 1, the utility model provides a kind of novel draught cupboard to dehumidify, including bookcase body, ventilation opening, it is described logical
Air port is located at the top of the bookcase body, is provided with wind-collecting cover at ventilation opening, the wind-collecting cover is connected with exhaust blower by conduit, institute
It states and is provided with filter in conduit, the avris of the bookcase body is provided with liftable glass baffle plate, is arranged on the glass baffle plate
There is Intelligent humidometer, dehumidifier, lighting system are additionally provided at the top of the bookcase body.
Specifically, the wind-collecting cover is internally provided with filter screen, in order to filtering poisonous gas.
Specifically, the wind-collecting cover is dismountable, it is therefore an objective to easy to clean and replacement filter screen.
Specifically, the catheter interior has depended on multi-layer porous sorbing material, the gas before discharge is carried out again
Filtering.
Start exhaust blower 5, the display data on dehumidifier 6 is observed, when the air humidity in bookcase body 1 cannot meet experiment sample
Air humidity needed for product carries out air humidity adjusting, before experimenter stands or is seated at bookcase body 1, by glass with regard to starting dehumidifier 6
Baffle 9 is lowerd as possible, and hand is tested by being put in cabinet under door.
Based on above-mentioned, the utility model has the advantage that：This utility model is using be filtered for multiple times can be as possible
The pernicious gas being discharged in air is filtered out, using dehumidifier, ensures the air humidity in show window, does not influence experimental result, this
Sample, which not only can guarantee, does not pollute air, ensures the humidity of draught cupboard, improves the accuracy of experimental result.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
