For above-mentioned problems of the prior art, this utility model provides a kind of efficient convenient air distributing device of use for laboratory, by increasing the flow process of mixed gas and mixed gas being carried out static agitation, it is achieved that abundant, the high efficient mixed to multiple gas with various.
The technical solution adopted in the utility model: the efficient convenient air distributing device of use for laboratory, mainly includes that the quantity of air inlet pipe and gas mixing tube, first air inlet pipe can be two, and two air inlet pipe are connected with gas mixing tube by three way cock；Electromagnetic valve, gas flow controller and Pressure gauge is set gradually respectively in described air inlet pipe；Described gas mixing tube is spiral bend pipe, and at the internal filling porous foam metal of gas mixing tube.
Optimize further, the quantity of described air inlet pipe can also be three, four, five, the six roots of sensation, seven or eight, the air inlet pipe of respective numbers is respectively by four-way, five-way, clematis stem, seven logical, eight logical or nine pass joints are connected with gas mixing tube, such that it is able to according to the mixing to multiple gas with various of the gaseous species realization required by gas-solid catalysis.
Optimizing further, the ratio between diameter and the diameter of gas mixing tube of described air inlet pipe is 1:(1.1-1.5) × N, wherein N is the quantity of air inlet pipe, N=2,3,4,5,6,7 or 8.So can ensure that the total amount gas importing in gas mixing tube from many air inlet pipe, air pressure will be caused because volume is compressed acutely to raise, it is therefore prevented that the damage that gas mixing tube and porous foam metal are caused by hyperbar.And, the gas mixing tube of major diameter is also convenient for filling and the cleaning of foam metal.
Optimizing further, the porous foam metal filled in described gas mixing tube is foamed aluminium.This is because the flourishing communication type air hole structure of foamed aluminium makes it have the high porosity and high aeration, and the little feature of unit weight also makes light being prone to of device move.
Optimizing further, the gas of described gas mixing tube flows out end and arranges Pressure gauge, and Pressure gauge is used for showing the air pressure change that final mixed gas enters before gas bomb or reactor.
Optimizing further, the gas of described gas mixing tube flows out end and arranges check-valves, and check-valves is used for preventing gas backflow phenomenon that is uneven due to two ends air pressure and that cause.
Optimizing further, described gas flow controller is digital control type mass flowmenter.Digital control type mass flowmenter can pass through the most manual adjusting gas flow, and convenient carry out the gas flow in air inlet pipe monitors the most accurately.
Optimizing further, the manometric measurement scope that described air inlet pipe and gas mixing tube are arranged is 0-25 Mpa, thereby may be ensured that the most manometric normal work, prevents because outranging the quick-fried table caused.
Optimizing further, described air inlet pipe and gas mixing tube use stainless steel material to make.
Optimizing further, described air inlet pipe is connected with high-pressure gas cylinder by air relief valve.
Blender is set to spiral gas mixing tube by this utility model, it is a significant increase gas flow process, make mixed gas carry out the flowing of long period and relatively long distance along spiral bend pipe, thus ensure have time enough to allow gas the most of the same race carry out sufficiently effective mixing.At the internal filling porous foam metal of gas mixing tube in this utility model, make use of the feature that the porous foam metal porosity is high, aeration is good.When mixed gas grade hole in porous foam metal walks flowing continuously, porous foam metal can play continual static agitation effect, thus to carrying out the degree of depth, sufficient mix and blend between gas the most of the same race, can also effectively filter the molecule impurity in mixed gas simultaneously.And, mixed gas is by porous foam metal and the inhibition of gas mixing tube inwall in flow process, and current rate gradually weakens and tends towards stability, and may finally be uniformly mixed, the mixed gas of steady air current.
First this utility model allows air inlet pipe connected by air relief valve and single gas high pressure gas bomb respectively, and open electromagnetic valve and make single gas flow into.According to the single gas flow needed for gas-solid catalysis, accurate adjusting gas flow controller controls single gas input.Pressure gauge in air inlet pipe can show air pressure change when single gas flows in real time.Then, the single gas in various inlet pipe is unified imports in gas mixing tube.Mixed gas in gas mixing tube along spiral bend pipe through relatively long distance and the flowing of long period, and continual navigate within the porous foam metal wherein filled, such that it is able to carry out abundant, mix efficiently.Finally, uniform, the stable mixed gas obtained can be passed through standby in air accumulator or be passed directly in reactor and react.
This utility model reasonable in design is ingenious, is easily worked making, uses safe and convenient, simple to operate, it is possible to achieve multiple different air-flow is carried out abundant, mix efficiently, convenient provide stable, uniform mixed gas for gas-solid catalysis in laboratory.
