Description
Technical field
The present invention relates to laboratory exhaust gas to extract collection device field, particularly belongs to a kind of laboratory exhaust gas and extracts collection dress
Put.
Background technology
Atmospheric environment protection is an important content of China Today environmental improvement.In The Atmosphere Over China pollution now is tight according to statistics
The industry of weight mainly has metallurgy, chemical industry, building materials, petrochemical industry etc..As country is to the growing interest of atmosphere pollution, the waste gas in laboratory
Pollution has caused the great attention of environmental administration.The pollution of laboratory exhaust gas can not only pollute air, go back entail dangers to in fact
Test the health of personnel.Mainly there are chloride waste gas, nitride waste gas, sulfide waste gas according to laboratory exhaust gas is investigated
And the pernicious gas such as volatile matter of hydrofluoric acid.For the characteristic of laboratory exhaust gas, the present invention provides a kind of laboratory exhaust gas and taken out
Take collection device.
The content of the invention
The present invention is directed to the characteristic of laboratory exhaust gas, researches and develops a kind of laboratory exhaust gas draw-out device, avoids laboratory exhaust gas
Pollute air and jeopardize experimenter's health.
The technical solution adopted by the present invention is as follows to achieve the above object：
A kind of laboratory exhaust gas extracts collection device, it is characterised in that the laboratory exhaust gas, which extracts collection device, includes ten thousand
To draft hood, exhaust tube, aspiration pump and waste gas collection device, the waste gas collection device includes containment housing and received with waste gas filtering
Header, the aspiration pump are arranged on above containment housing, and case is collected by filtration in the middle part of containment housing in waste gas, and exhaust tube is in succession
In closed box bottom, universal draft hood and exhaust tube are in succession.
A kind of laboratory exhaust gas extracts collection device, it is characterised in that laboratory exhaust gas, which extracts collection device, includes multiple take out
Tracheae, misplace in succession between each two exhaust tube, between exhaust tube using universal elbow bend in succession.
Waste gas is collected by filtration case and is divided into three-decker in the waste gas collection device, and first layer is moist cellular activated carbon
Adsorbent is carried out, the second layer is SDG acid gas adsorption layers, and third layer is anhydrous calcium chloride drying layer, and three-decker is thick
Degree is than being 1:1:1.5, three-decker density ratio per cubic centimeter is 3:3:1.
Compared with the prior art, beneficial effects of the present invention are as follows：
Combined by carrying out decision design with waste gas collection device to universal draft hood, exhaust tube, aspiration pump, it is real into one kind
Room exhaust extraction collection device is tested, chloride waste gas, nitride waste gas, sulfide waste gas and hydrofluoric acid in laboratory are waved
The pernicious gases such as stimulating food are collected and purified, and avoid laboratory exhaust gas pollution air and jeopardize experimenter's health.
Present invention extraction waste gas effect is good, purification waste gas effect is good, is adapted to promote the use of in the lab.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Embodiment
Referring to accompanying drawing:A kind of laboratory exhaust gas extracts collection device, it is characterised in that the laboratory exhaust gas, which extracts, collects
Device includes universal draft hood 1, exhaust tube 2, aspiration pump 3 and waste gas collection device 4, and the waste gas collection device 4 includes closed
Case 401 is collected by filtration with waste gas in casing 402, and the aspiration pump 3 is arranged on the top of containment housing 402, and case 401 is collected by filtration in waste gas
Installed in the middle part of containment housing 402, exhaust tube 2 is in succession in closed box bottom, and universal draft hood 1 and exhaust tube 2 are in succession.It is described every
Misplaced in succession between two exhaust tubes 2, between exhaust tube 2 using universal elbow bend 5 in succession.In the waste gas collection device 4
It is moist cellular activated carbon progress adsorbent 4013 that waste gas, which is collected by filtration case 401 to divide for three-decker, first layer, the
Two layers are SDG acid gas adsorptions layer 4012, and third layer is anhydrous calcium chloride drying layer 4011, and three-decker thickness ratio is 1:
1:1.5, three-decker density ratio per cubic centimeter is 3:3:1.
