Abstract
Said invention refers to the method and device for preparing low purity oxygen or oxygen-enriched air by magnetic force separating air. Said device consists of permanent magnet, oxygen channel and electric heater. When air is near the non-uniform magnetic field, the oxygen in air is magnetized, the volume susceptibility is raised, and the oxygen is attracted into oxygen channel. The volume susceptibility of attracted oxygen becomes lower. The attraction force to rear cold oxygen is larger than that of hot oxygen, a propelling force is formed to make oxygen move. Thermal magnetic convection is formed, so the oxygen is separated from air.
Description
The present invention relates to a kind of air separating method and device, be particularly suitable for air separation and produce low-purity oxygen or oxygen-enriched air.
At present, the air separation method of producing oxygen mainly contains cryogenic refrigeration method, pressure swing adsorption method and membrane process.Wherein cryogenic refrigeration method is the most ripe, and commercial Application is the most extensive.But with this method system oxygen complex process, equipment is huge, and amount of investment is big.Pressure swing adsorption method and membrane process also differ with a certain distance from commercial Application owing to there are problems such as system oxygen energy consumption is big, resolution element (molecular sieve and film) costs an arm and a leg, service life is short.
The present invention aims to provide and a kind ofly makes the oxygen energy consumption is low, equipment is simple, the air separating method and the device of cheap, long service life.
The present invention is made up of essential parts such as permanent magnet, oxygen channel and electric heating bodies.Oxygen channel is made of non-magnet material, symmetric arrangement permanent magnet on one end both sides, and permanent magnet produces non-uniform magnetic field in oxygen channel, and the remnant field intensity of permanent magnet is greater than 1 special Lars; Electric heating body is arranged in the stage casing of oxygen channel, can place in the oxygen channel, also can place outside it, and electric heating body uses 220 volts of AC powers.When air is flowed through oxygen channel end face near permanent magnet, airborne oxygen is magnetized by non-uniform magnetic field, volume susceptibility raises, and is entered oxygen channel by poles attract, and these oxygen are heated by electric heating body, volume susceptibility reduces, the cold oxygen in back is subjected to the oxygen of the attraction specific heat in magnetic field to want big many, thereby produce a motive force oxygen is continuously moved forward, and forms thermomagnetic convection, so oxygen is separated, make low-purity oxygen or oxygen-enriched air from air.
Advantage of the present invention is that permanent magnet produces the not other consumed energy in magnetic field, and there is not phase-state change in the separation process of gas, and gas is carried with the dispatch resistance little, thereby system oxygen energy consumption significantly reduces; Simultaneously, the permanent-magnet material low price, selectivity is wide; System oxygen critical piece does not have mechanical movement, does not have mechanical wear, long service life.Therefore, the present invention can provide that equipment manufacturing cost is low, system oxygen energy consumption is low, the air separation plant of long service life, can produce cheap industry, civilian, medical oxygen or oxygen-enriched air.
Below in conjunction with accompanying drawing the present invention is done further detail explanation.
Fig. 1 is a principle of the invention schematic diagram.
Fig. 2 is an embodiment of the invention structural representation.
Magnetic air separating method of the present invention and device comprise essential part: permanent magnet (1,2), oxygen channel (3), electric heating body (4) and slave part: soft magnetic bodies (8), the overanxious cover of air (10), blowing fan (11), air delivery passage (12) and shell (9); Oxygen channel (3) is made by non-magnet material, and permanent magnet (1,2) symmetry is positioned at oxygen channel (3) one end both sides, produces non-uniform magnetic field in oxygen channel (3); Permanent magnet (1,2) be shaped as taper, a less end is near oxygen channel (3), a bigger end is fixed on the soft magnetic bodies (8), the remnant field intensity of permanent magnet is greater than 1 special Lars; Soft magnetic bodies (8) is fixed on the shell (9), is mainly used in armoured magnetic field, forms magnetic circuit; Oxygen channel (3) one ends are fixed on the shell (9), and the other end passes through sealing ring (13) sealed attachment at the middle part of air delivery passage (12), and are connected with air delivery passage; Electric heating body (4) can place in the oxygen channel (3), also can place outside the oxygen channel (3), to heat oxygen most effectively, produces thermomagnetic convection and is advisable, and electric heating body uses 220 volts of AC powers; Air filter housing (10) places air delivery passage (12) arrival end, plays a part to filter, purify air; The blowing fan (11) of conveying air is arranged in the porch of air delivery passage (12); Air delivery passage (12) two ends directly connect with shell (9).Air is sent into air delivery passage (12) by air filter housing (10) through blowing fan (11), during through oxygen channel (3) end face, wherein oxygen (6) is at permanent magnet (1,2) the non-uniform magnetic field effect that is produced is magnetization down, volume susceptibility raises, entered oxygen channel (3) by poles attract, after electric heating body (4) heating, be transformed into the low oxygen of volume susceptibility (7), because oxygen (6) is subjected to the attraction in magnetic field more much bigger than oxygen (7), thereby produce a motive force oxygen is continuously moved forward, form thermomagnetic convection, so, oxygen is continuously separated from air, thus low purity oxygen production gas or oxygen-enriched air; Nitrogen-rich air behind the oxygen separation is by outside the air delivery passage outlet discharger.
