Traditional nitrogen purification equipment is by nitrogen emptying device, deoxygenator, water cooler, absorption type dryer, dust secondary filter, controller, forms with pipe connection, and the nitrogen emptying device has comprised oil eliminator, cold dried device, activated charcoal filter, snubber.Because nitrogen and oxygen all are more active gas, so, in producing the process of nitrogen, no matter be to add carbon deoxygenation purifying, or the deoxidization by adding hydrogen purifying, difficulty is separated oxygen from general nitrogen, more difficultly oxygen impurities is eliminated the not high major cause of nitrogen gas purity that Here it is in nitrogen.So-called " general nitrogen ", what come to this is a kind of because the nitrogen deoxidation not to the utmost also contains the ordinary nitrogen of oxygen impurities.With traditional nitrogen purification equipment, the nitrogen of acquisition, its purity, just slightly high than general nitrogen, but do not reach requirement far away as 99.995% high-purity nitrogen.
Along with the progress and development of society at aspects such as science and technology, epoch, as nitrogen Application Areass such as electronics, thermal treatment, food, chemical industry, chemistry, medicine, requirement to nitrogen gas purity is also more and more higher, thereby, become the requirement that must improve the equipment of making nitrogen and technical process.Have only emphatically by the equipment of making nitrogen is transformed, and the improving of corresponding nitrogen producing craft and flow process, could to greatest extent the oxygen impurities in the general nitrogen be removed, make high-purity nitrogen, just can help relevant industries and adapt to social development, could satisfy the demand of relevant industries nitrogen purification equipment and high-purity nitrogen.This is final, a challenge that has become the air separation plant production to face and to set about finishing undoubtedly.
Summary of the invention:
Order of the present utility model provides the automatic hydrogenation purifier apparatus of a kind of nitrogen, its objective is such realization: by nitrogen emptying device, deoxygenator, water cooler and the absorption type dryer that is being linked in sequence, dust secondary filter, controller, form with pipe connection; On the pipeline between general nitrogen inlet and the interchanger, be provided with threeway, and, be connected with threeway with the pipeline that vacuum breaker one end is arranged, be provided with automatic hydrogenation unit; Between deoxygenator and water cooler or deoxygenator and threeway, be provided with interchanger, and, pass the heat exchange jar with two pipelines,, the two ends of pipeline, French Franc with threeway, deoxygenator lower end connects respectively, and the two ends of another pipeline connect with the French Franc of deoxygenator upper end, the French Franc of water cooler lower end respectively.
Owing to adopted such scheme, by in nitrogen purification equipment, being provided with automatic hydrogenation unit of nitrogen and interchanger, not only, make nitrogen before deoxidation, just can be subjected to preheating, played the effect of save energy, the oxygen that more helps in the nitrogen fully reacts with hydrogen in deoxygenator, improve deoxidation effect, and, in needing the general nitrogen of deoxidation, added hydrogen in advance, made general nitrogen and hydrogen before deoxidation, be subjected to preheating simultaneously, can also be according to the demand of the oxygen in the general nitrogen of in deoxygenator, measuring to hydrogen, automatically regulate the add-on of hydrogen, fully remove the oxygen impurities in the nitrogen.Thereby, greatly improved the purity of nitrogen.This technical scheme, both further perfect nitrogen purification equipment and technical process, further promoted the nitrogen purification technological layer again,, provide technical qualification for producing high-purity nitrogen, satisfying the demand of high-purity nitrogen Application Areas to high-purity nitrogen and nitrogen purification equipment.
