Description
Technical field
The present invention relates to the field of molecular-sieve oxygen generator, particularly relate to a kind of molecular-sieve oxygen generator and electromagnetic balance valve thereof.
Background technique
Oxygen is to keep the indispensable material of human life, however some in particular cases people have to perhaps need the oxygen of higher concentration in the face of lacking the environment of oxygen, based on this demand, oxygen generating plant is used and is given birth to.
People generally are divided into two classes to the demand of oxygen: be used for correcting the pathologic anoxic, that treats disease is called oxygen therapy with oxygen, and the urgent oxygen therapy that wherein is used for the rescue urgent patient is called again first aid oxygen therapy; Be used for to correct the physiological anoxic, with build up health, prevent disease and improve working and learning efficient etc. be referred to as the oxygen health care with oxygen.
Oxygen therapy mainly adopts oxygen technique to have three kinds with oxygen and oxygen oxygen for health care: chemical-agent technique, Deep Cooling Method, pressure swing adsorption method.Wherein the omnibus control system subtraction unit is simple, little investment, and cost is low, and automaticity is high, and is easy to operate, flexibly and can reach fast and use the oxygen requirement, the small-sized molecular-sieve oxygen generator that is convenient for carrying of more suitable making.
Pressure swing adsorption starts from 20th century the fifties, and the idea of oxygen separation and nitrogen derives from Skarstron circulation and the Gerin-Domine circulation of 1958 at first from air.But due to the restriction of zeolite molecular sieve technology at that time, pressure-variable adsorption fails to be applied to air-separating oxygen-making.Until artificial synthetic zeolite's technology in 1970 has had greater advance, pressure swing adsorption method just begins for air-separating oxygen-making.
PSA(Pressure Swing Adsorption, pressure-variable adsorption) molecular-sieve oxygen generator, be called for short molecular-sieve oxygen generator.Molecular-sieve oxygen generator all has left and right two molecular sieve tanks (hereinafter to be referred as left tank, right tank), when left tank during in pressurization inflation oxygen, right tank decompression exhaust, left tank partly fills into right tank so that the toxic emission in right tank is totally thorough with the oxygen that makes simultaneously, has also greatly promoted the initial gas pressure (being commonly called as " all pressing ") in right tank.Within each " pressurization absorption-decompression resolve " cycle, the left and right tank above-mentioned oxygen preparation that hockets.
The pressurization inflationtime of left and right two tanks of present domestic molecular-sieve oxygen generator and decompression exhaust time are that equate and invariable, two tanks also just mutually all press tonifying Qi by the throttle valve normal open hole of fixing simply, and the oxygen that the pressurization aeration tank fills in the decompression exhaust tank also continues, and runs through whole oxygen preparation.
In fact all there is a little difference all the time in molecular sieve amount, filling process and the supplied materials in left and right two tanks, and along with the prolongation of time of machine work, molecular sieve performance in two molecular sieve tanks must be decayed, therefore adopt consistently fixing fill, period of exhaust is difficult to guarantee that molecular-sieve oxygen generator has stable oxygen concentration output, also be difficult to give full play to the performance of two tanks, because the performance of two tanks is difficult to obtain equilibrium, indirectly shortened the working life of molecular sieve.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of electromagnetic balance valve that is applied in molecular-sieve oxygen generator, has solved in the prior art the unstable and molecular sieve short defective in working life of the oxygen concentration of molecular-sieve oxygen generator.
