Abstract
The utility model relates to a gas purification and emission device for a laboratory. The gas purification and emission device for the laboratory is characterized by comprising a collection cover provided with a hollow inside and used for covering the outer side of an experimental apparatus. A gas inlet is arranged at the bottom of the collection cover, the top of the collection cover is connected with a gas suction pipe, a gas inlet of the gas suction pipe is provided with a gas suction fan, a gas outlet of the gas suction pipe is firstly connected with a purification pipe and then communicated with a gas inlet of an exhaust pipe, and a gas outlet of the exhaust pipe is communicated with a gas exhaust port of the laboratory. Compared with the prior art, the gas purification and emission device for the laboratory has the advantage of being capable of completely purifying and emitting toxic or malodorous gas generated in the experiment process in the laboratory to ensure the environment of the whole laboratory to be safe and sanitary.
Description
Technical field
The utility model relates to a kind of laboratory gas purification tapping equipment.
Background technology
Do in the experimentation in the laboratory; Often need heating or some materials that burn; Some are poisonous, foul gas discharges and a lot of materials have in heating or the regular meeting of burning often; Although present laboratory major part is provided with some auxiliary equipment such as vent cabinet, vent cabinet can not guarantee that still these are poisonous, foul gas all emits.When some experimental example is measured as carrying out the pitch wax content, tend to make whole laboratory building all to feel stench, this has not only influenced normal experimental work, but also contaminated air has all brought harmful effect to health and environment.
The utility model content
The utility model technical problem to be solved is to provide a kind of to above-mentioned prior art can effectively control the laboratory gas purification tapping equipment that the laboratory is poisonous, foul gas purifies and discharges.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this laboratory gas purification tapping equipment; It is characterized in that: comprise collecting hood inner hollow, that be used to be located at the laboratory apparatus outside; This collecting hood bottom is provided with air inlet, and this collecting hood top is connected with exhaust tube, and the air inlet of exhaust tube is provided with exhaust fan; The gas outlet of exhaust tube is communicated with the air inlet of blast pipe after connecting purification pipe, and the gas outlet of blast pipe then is communicated with breadboard exhaust outlet.
As improvement, said exhaust fan is outside equipped with screen pack.
Improve, said collecting hood is hemispherical or semielliptical shape again.
Improve, the bottom margin of said collecting hood evenly is provided with a plurality of arc air inlets again.
Improve, said collecting hood is transparent collecting hood again.
Improve, said collecting hood is provided with a grid again.
Improve again, be provided with sorbing material in the said purification pipe.
Compared with prior art; The advantage of the utility model is: the laboratory gas purification tapping equipment that uses the utility model to provide; Can the poisonous or foul gas that experimentation in the laboratory produces be purified fully and discharge, thereby guarantee the safety and the health of whole laboratory environment.
Description of drawings
Fig. 1 is the structural representation of gas purification tapping equipment in laboratory among the utility model embodiment.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Gas purification tapping equipment in laboratory as shown in Figure 1; It comprises transparent collecting hood 1 inner hollow, that be used to be located at the laboratory apparatus outside, and this transparent collecting hood 1 is hemispherical, and bottom margin evenly is provided with a plurality of arc air inlets 11; Collecting hood 1 is provided with a grid 7; This collecting hood 1 top is connected with exhaust tube 2, and the air inlet of exhaust tube 2 is provided with exhaust fan 3, and exhaust fan 3 is outside equipped with screen pack 4; The gas outlet of exhaust tube 2 connects purification pipe 5 backs and is communicated with the air inlet of blast pipe 6, and the gas outlet of blast pipe 6 then is communicated with breadboard exhaust outlet 8; Be provided with porous carbon or other adsorption cleaning materials in the purification pipe 5.
Collecting hood 1 by transparent, do not fire, the high temperature resistance material processes, and can conveniently observe whole experiment, also experimenter's safety played protection effect simultaneously; Door grid 7 by transparent, do not fire, the high temperature resistance material processes, hand or the health of being convenient to the experimenter can conveniently get into the operation experiments instrument; Screen pack 4 can filter and remove some dusts and the smog in the gas.Collecting hood 1 bottom margin evenly is provided with a plurality of arc air inlets 11, is convenient to exhaust fan 3 and evenly absorbs air from the outside, and can not cause negative pressure or influence the test that some need burn;
During experiment; Produce laboratory apparatus cover poisonous, foul gas with whole earlier with collecting hood 1, open exhaust fan 3 then, exhaust fan 3 is started working; Poisonous, the foul gas that is produced in the experimentation like this is through exhaust fan 3 suction exhaust tubes 2; Then the purification pipe 5 of process porous arc property carbon or other adsorption cleaning materials adsorbs and purifies, and eliminates poisonous and foul gas, and purification pipe 5 can be changed at any time; Nontoxic, no odour after the purification by blast pipe 6 outside laboratory exhaust outlet 8 discharge laboratories, with safety and the health that guarantees whole laboratory environment.
Claims (7)
