Description
Technical field
The utility model relates to a kind of pressure swing adsorption process device of oxygen producing and nitrogen simultaneously, produces oxygen and the oxygen nitrogen all-in-one of nitrogen in the time of especially can be energy-conservation.
Background technology
Making nitrogen by pressure swing adsorption be utilize sorbent material to nitrogen, oxygen the difference at aspects such as adsorptive capacity, rate of adsorption, adsorptive poweies, and the characteristic that changes with the variation of pressure of the loading capacity of sorbent material, under pressurized conditions, isolate nitrogen, during step-down, desorption goes out oxygen enrichment tail gas, thereby realizes the separation of air and recycling of sorbent material.The gas consumption ratio of making nitrogen by pressure swing adsorption technique is 1: 3 left and right at present, i.e. the nitrogen that every generation is one cubic metre is by the oxygen-rich air (oxygen content is wherein about 40%) of discharging two cubic metres, and this part gas directly enters atmosphere, causes certain wasting of resources.When the oxygen that oxygenerator is 21% by content in air purifies to 90%, consume energy higher, it is obvious that the oxygen enrichment tail gas that oxygen level is 40% if use purifies to 90% energy-saving effect as unstripped gas.In part Nitrogen plant application enterprise, not only need nitrogen also to need a certain amount of oxygen, for example smelter is used nitrogen to protect gas for metallurgy, and boiler auxiliary combustion needs oxygen rich gas.At present Zhe Lei enterprise will buy a set of swing adsorption nitrogen producing apparatus and a set of pressure swing adsorption oxygen making device cost is higher, and running energy consumption is higher.
Summary of the invention
In order to prevent the oxygen enrichment stripping gas wasting of resources that directly discharge causes in Nitrogen plant discharge gas, and reduce the energy consumption of oxygenerator, the utility model provides a kind of oxygen nitrogen all-in-one, the stripping gas that this oxygen nitrogen all-in-one is discharged Nitrogen plant is supplied with oxygenerator as unstripped gas, and add time variable control automatic air supply device, to guarantee that oxygenerator source of the gas is sufficient, thereby realize an equipment output oxygen and nitrogen simultaneously, and manufacturing cost and operation energy consumption reduction.
The technical scheme that the utility model technical solution problem adopts is: Nitrogen plant exhaust side, oxygen enrichment tail gas storage tank, gas blower, oxygenerator inlet end is linked in sequence, it is characterized in that: Nitrogen plant exhaust side connects oxygen enrichment tail gas storage tank, Nitrogen plant stripping gas enters oxygen enrichment tail gas storage tank, through gas blower, extract and enter oxygenerator inlet end again, in the connecting pipeline of oxygen enrichment tail gas storage tank and gas blower, there is the branch of an automatic inflating device, time variable control pneumavalve and air filter are installed in this branch, form an automatic air supply device, when Nitrogen plant stripping gas undersupply, pneumavalve is opened, gas blower extracts raw air and supplies with oxygenerator from atmosphere.Wherein, described automatic air supply device comprises gas blower, supercharger and three kinds of air extractors of compressor.Described automatic air supply device comprises time variable control pneumavalve and two kinds of time variable control opening devices of magnetic valve.
The beneficial effects of the utility model are: when producing nitrogen, can produce oxygen, also can as Nitrogen plant or oxygenerator, use separately, be a kind of new energy-saving equipments that integrates nitrogen-making device and oxygenerator, and manufacturing cost and operation energy consumption reduce.
