Background technology:
In the chemical experiment process; discharge the gas harmful through regular meeting to health, serious harm experimenter healthy, for this reason; people take to install in the chemical experiment place mode of ventilation unit usually, suck pernicious gas farthest to avoid the chemical experiment personnel.All ventilation units all have only the ventilation function, and pernicious gas are not carried out any purified treatment, make pernicious gas directly arrange people's atmosphere, become the new pollution sources of atmosphere but up to now.
Summary of the invention:
The purpose of this invention is to provide a kind of can the purification, avoid the device of chemical experiment dusty gas pollutant atmosphere the dusty gas that produces in the chemical experiment.
Technical solution of the present invention is: a kind of portable chemical experiment fume hood with purifier, it is characterized in that: be provided with at least two cabinet stay pipes 1, be connected to experimental implementation platform 2 with cabinet stay pipe 1, be connected to the observation window of making by transparent material 4 between air admission hole 3, the cabinet stay pipe 1 being provided with on the cabinet stay pipe 1 of experimental implementation platform 2 upper ends, be provided with gas cleaning plant 5 below the experimental implementation platform 2, the air-introduced machine 6 that is provided with in the gas cleaning plant 5 joins with the gas outlet 7 that is arranged on the cabinet stay pipe 1.
Be connected to closure plate 8 and horizontally disposed base plate 9 between the cabinet stay pipe 1 below described experimental implementation platform 2, purifier 5 places on the base plate 9.
Described base plate 9 is a cored slab, and air-introduced machine 6 joins by the hollow and gas outlet 7 of base plate 9.
The exhaust outlet 10 of described gas cleaning plant 5 is for being located at the vertical hole on the base plate 9.
The lower end of described base plate 9 is connected to universal wheel 11.
Also be provided with movable window 13 between the described cabinet stay pipe 1 on experimental implementation platform 2.
Described gas cleaning plant is provided with the dusty gas exhaust duct 14 that joins with air-introduced machine 6, is provided with the adsorption layer 15 that adsorbent is housed in exhaust duct 14.
In dusty gas exhaust duct 14, also be provided with spray equipment 16.
Described spray equipment 16 is for to be provided with and to spray the spray liquid input pipe 18 that water tank 17 joins, and spray liquid input pipe 18 is provided with nozzle 19, is provided with and sprays the spray liquid discharge pipe 20 that water tank 17 joins on exhaust duct 14, also is connected to pump 21 with spray water tank 17.
The present invention compares with prior art, drain in the atmosphere again after the dusty gas that produces in the chemical experiment can being collected, purified, overcome the disadvantage that chemical experiment ventilation unit in the past only ventilates and do not purify, can avoid the chemical experiment personnel to suck pernicious gas, can avoid chemical experiment gas pollution on the environment again.The cabinet type design of especially whole device can make the toxic gas that produces in the chemical experiment process enter in the purifier by the cabinet stay pipe fully and purify; The universal wheel that cabinet stay pipe lower end is provided with can move arbitrarily as required, to choose the optimum position of being convenient to the observation of students experiment; And the setting of the spray water tank in the purifier can make the spray liquid body recycle, and has saved the expense of spray cleaning.
Description of drawings:
Fig. 1 is an embodiment of the invention structural representation.
Fig. 2 is the partial sectional view of the embodiment of the invention.
Fig. 3 is a purifier structural representation in the embodiment of the invention.
The specific embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1, 2: the embodiment of the invention has 8 cabinet stay pipes 1,4 cabinet Supporting vertical tubes and 4 cabinets support transverse tubes that join with 4 cabinet Supporting vertical tube tops, cabinet stay pipe 1 can be made with the tubing of various materials such as plastics or aluminium alloy, and tubing can be different shapes such as square tube, pipe.In the middle and lower part of four cabinet Supporting vertical tubes a plane that joins with cabinet stay pipe 1 is arranged, promptly the experimental implementation platform 2.The cabinet stay pipe 1 of experimental implementation platform more than 2 is provided with a plurality of air admission holes 3, and air admission hole 3 can only be located on the cabinet Supporting vertical tube, also can be located at cabinet and support on the transverse tube, or be located on cabinet Supporting vertical tube and the cabinet support transverse tube.Be connected to the observation window of being made by transparent material 4 between the cabinet stay pipe 1, wherein a fan observation window can be movable window 13, and preferably electronic movable window.Be provided with gas cleaning plant 5 below the experimental implementation platform 2, can fix, but air-introduced machine 6 that is provided with in the gas cleaning plant 5 and the gas outlet 7 that is arranged on the cabinet stay pipe 1 are joined with experimental implementation platform bottom surface.Embodiments of the present invention are to be connected to closure plate 8 and horizontally disposed base plate 9 between the cabinet stay pipe 1 below described experimental implementation platform 2, purifier 5 places on the base plate 9, be that purifier 5 is enclosed in the closure plate 8 formed spaces, make whole device profile better appearance.Base plate 9 can be cored slab, forms collection chamber.Air-introduced machine 6 joins by the gas outlet 7 of the hollow of base plate 9 with cabinet Supporting vertical tube 1 lower end, and the exhaust outlet 10 of gas cleaning plant 5 is for being located at the vertical hole on the base plate 9.Can below base plate 9, connect 4 and be convenient to the universal wheel 11 that device moves.Gas cleaning plant can be as shown in Figure 3: be provided with the dusty gas exhaust duct 14 that joins with air-introduced machine 6, whole exhaust duct 14 is with flange fixing bend pipe, straight tube.Adsorption layer 15 is installed in exhaust duct 14, and adsorption layer 15 is made of adsorbent (active carbon).In order to make clean-up effect better, in dusty gas exhaust duct 14, also can be provided with spray equipment 16.Spray equipment 16 is for installing the spray liquid input pipe 18 that joins with spray water tank 17 in the dusty gas exhaust duct 14 again, input pipe 18 is provided with nozzle 19, be provided with and spray the spray liquid discharge pipe 20 that water tank 17 joins in the lower end of exhaust duct 14, also be connected to pump 21 with spray water tank 17.
