Background technology
In pressure swing adsorption oxygen, the highest is tower adsorber, so, reduce the height of oxygenerator, will start with from the height that reduces adsorber.At present, under the certain situation of compressor power, the method that reduces the adsorber height has three kinds: (1) selects for use the superior sorbent material of absorption property can reduce its consumption, thereby reduces the adsorber height, obviously, certainly will increase manufacturing cost like this.(2) improvement of technical process, promptly increasing equal compression technology can cut down the consumption of energy effectively, reduces sky oxygen ratio, improves the rate of recovery, simultaneously, has reduced the consumption of sorbent material.(3) increase the adsorber diameter, reduce aspect ratio, thereby improve adsorber structure.But under the certain condition of oxygen-producing amount, oxygen concentration is to increase afterwards earlier to reduce with the increase of aspect ratio, so to reduce it highly be limited by reducing the adsorber aspect ratio.
At present, each adsorber in the widely used double-tower type adsorber has monotubular formula and telescoping structure type again, owing to guarantee certain aspect ratio, each adsorber height reduction is subjected to certain restriction all the time.Therefore, how research greatly reduces the height of adsorber, reduces the volume of oxygenerator, is the objective of the struggle of those skilled in the art all the time.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, reduces the adsorber height, reduces the pressure swing adsorption oxygen of the multistage adsorber of oxygenerator volume.
The pressure swing adsorption oxygen of the utility model multistage adsorber, comprise adsorber by valve body and pipe connection, wherein adsorber comprises the lower end cover that is provided with the inlet, outlet interface, on lower end cover, with the inlet, outlet interface is the left and right shell that tubular is equipped with at the center respectively, the upper end of left and right shell is tightly connected with upper end cover respectively, is provided with the spiral groove that left and right shell inner cavity is communicated with on the internal surface of upper end cover; In left shell, be equipped with respectively down, in, on spreader plate, the center between lower end cover and the following spreader plate is fixedly connected by spring, in, fill activated alumina between time spreader plate, between last, middle spreader plate, fill sorbent material; Upper and lower spreader plate is housed respectively in right casing, also fills sorbent material between upper and lower spreader plate, the center between lower end cover and the following spreader plate is fixedly connected by spring.
The pressure swing adsorption oxygen of the utility model multistage adsorber wherein is tightly connected with the web plate that is provided with through hole respectively in the upper end of left and right shell, and web plate and upper end cover are tightly connected.
The pressure swing adsorption oxygen of the utility model multistage adsorber, wherein the diameter of left and right shell is identical, and aspect ratio is 1～1.5.
The pressure swing adsorption oxygen of the utility model multistage adsorber is each adsorber in the double-tower type adsorber to be blocked be the two-part structure, and two sections aspect ratio is 1～1.5.For each adsorber, having guaranteed to have reduced the height of adsorber under the constant situation of aspect ratio, make whole oxygenerator height that bigger reducing be arranged, volume also obviously diminishes, but oxygen-producing amount is constant, and be convenient to the installation and transportation of equipment.
