The specific embodiment
Embodiment 1 is as shown in Figure 1.Present embodiment is a kind of method of utilizing air deoxygenation impurity elimination to prepare gas; And the device of realizing this method; This device comprises the airtight container 1 that is full of air, firing chamber 3, cooling washing pool 4, dirt pocket 5 etc., by pipeline 6 airtight container 1, firing chamber 3, cooling washing pool 4, dirt pocket 5 is communicated with; In order to guarantee that gas flows, and is provided with described air pump 2 on the pipeline 6 between airtight container 1 and the firing chamber 3 between airtight container 1, firing chamber 3, cooling washing pool 4, dirt pocket 5; For the gas that flows is controlled, on the pipeline between airtight container 1, air pump 2, firing chamber 3, cooling washing pool 4, the dirt pocket 5, be respectively arranged with the 5th valve 7, first valve 8, second valve 9, the 3rd valve 10 and the 4th valve 11.In order to guarantee that the air pressure in the airtight container 1 remains on a standard atmospheric pressure; In firing chamber (3), replenish the pressure-equalizing passageway 12 of air; Pressure-equalizing passageway 12 is communicated with firing chamber (3) through the 6th valve 13; The 6th valve 13 is opened when airtight container 1 air pressure is lower than 1 standard atmospheric pressure, and air carries out deoxygenation from the external world through pressure-equalizing passageway 12 entering firing chambers 3, enters into airtight container 1 through cooling washing pool 4, dirt pocket 5 then; After gas process air pump 2 in the airtight container 1, firing chamber 3, cooling washing pool 4, dirt pocket 5 circular treatment; The little oxygen table 14 that on airtight container 1, is provided with can be measured oxygen content in the airtight container 1, when the micro amount of oxygen table shows less than 5ppm, stops circulation, accomplishes system gas task.
Solid reductant and heater are set in firing chamber 3; Reducing agent mainly contains metal such as iron, aluminium or other combustible such as carbon etc., and perhaps the mixture of these reducing agents uses activated carbon in the present embodiment, also can use aluminium powder.Heater is heated to 500 degree, consume oxygen to greatest extent with these reducing agents.
The pipeline opening that cooling washing pool 4 one ends are connected to firing chamber's 3 other ends is arranged in the water, is connected to dirt pocket 5 and is arranged on the water surface; Through the gas temperature of firing chamber 3 than higher, after washing, in the fused water of solable matter wherein.
In dirt pocket 5, be provided with air filter.
The course of work of this device: in sealing system, the high-temp solid reducing agent (like C or metal) in the firing chamber 3 carries out roasting after adding moving air, makes the rapid and high temperature reduction agent reaction of airborne oxygen, generates CO
2, CO or metal oxide, product is blown away by flowing gas, high temperature is removed organic matter, bacterium (having a liking for oxygen bacterium, anaerobic bacteria), virus, filthy peculiar smell, is had impurity such as corrosivity dust simultaneously.These remaining high-temperature gases move on through cooling washing pool 4, obtain cooling and washing at the Chi Shuizhong of cooling washing pool 4, have become the remaining gas under the room temperature, pass through dust removal and filtration again, become " anaerobic pure air " and feed storeroom (airtight container 1).The storage room air has only part to participate in roasting during beginning, through continuous circulation roasting, very soon oxygen depletion in the storeroom, makes whole storeroom be full of " anaerobic pure air ".
Working. Step:
1. at first all open first to the 5th valve;
2. energising preheating in firing chamber's gets into duty.The firing chamber is stainless steel (or pottery) electric heating coil, fills charcoal (deoxidier) in the circle, is preheating to 500
0C;
3. start air pump, make and circulate air-flow.Air pump extracts the storage room air and becomes and be air flow, gets into the firing chamber and participates in roasting, and oxygen and impurity in the air flow are removed, and the while also is heated.High temperature residual gas after these deoxygenation removal of impurities; Move on; Get into the cooling washing pool, the calorie of the high-temperature gas water that is cooled is taken away into room temperature, in the just fused water such as reaction product, ashes, acid, alkali; The gas that from water, comes out also can be brought the steam on the water surface of pond into, and this gas has not been dry gas (like the condenser pipe through " cooling bay " time then be dry gas).These room temperature air move on again, through the air filter in the dirt pocket, the dirt dedusting is arranged, dustlessly directly go into storeroom, and the oxygen content in the storeroom has been reduced, and this is a flow process of deoxygenation removal of impurities.Along with air pump is constantly sent into the firing chamber to the storage indoor gas; Oxygen content in the storeroom is just fewer and feweri; When the micro amount of oxygen table shows less than 5ppm, explain to be equivalent to anaerobic state that air pump and firing chamber quit work; Five valve Close Alls, device are accomplished once system " anaerobic pure air " process.The effect of the 6th valve 13 once is described; The 6th valve 13 is check valve: when oxygen in the air becomes oxide and ashes, impurity etc. and fuses in water; Cause closed system negative pressure (less than 0.1MPa), valve 6 work this moment, outside air gets into pipeline and participates in roasting; Reach internal and external pressure balance, sealing system does not have pressure.
