Problems solved by technology

The operating costs of the oxygen generator, such as power consumption and replacement costs of consumables, will also increase significantly
[0008] In addition, because the specifications of the air compressor, air storage tank and oxygen storage tank are enlarged, not only a large installation space for the oxygen generator is required, but also

Embodiment Construction

[0035] The present invention to achieve the above objects will be described in detail below with reference to the accompanying drawings.

[0036] At first, according to the present invention, the simple composition of the oxygen generator 1 that is equipped with multiple adsorption towers, such as figure 1 As shown in , the air compressor 2 (air compressor), air dryer 3 (air dryer), air storage tank 4 and pressure regulator 5 are connected to the compressed air supply pipe and installed in the multiple adsorption tower 10. The inlet side of the multiple adsorption tower 10 is connected to the outlet side of the nitrogen gas storage tank 6.

[0037] figure 1 The content shown in is that four adsorption towers between the first adsorption tower 11 and the fourth adsorption tower 14 are installed to form two multiple adsorption towers 10, figure 2 and image 3 1 and 2 respectively represent the situation that a total of six adsorption towers between the first adsorption tower...

Abstract

The present invention relates to an adsorption column for an oxygen generator and a control method thereof, concretely to a multi-adsorption column formed by two or three groups of absorption columns, each group is composed of two adsorption columns, furthermore, an air supply calandria, a nitrogen discharge calandria, an oxygen supply calandria, an uniformization calandria and the like constitute a group, which is arranged on an inlet and an outlet of the absorption column respectively. The multi-absorption column is controlled by valves to perform adsorption (oxygen generation) and disengaging (nitrogen discharge) and uniformization operation by each group by turns for some time, so as to effectively reduce compressed air flux discharged from an air compressor and oxygen flux discharged from the adsorption column as well as pressure amplitude, furthermore, an air compressor for generating oxygen and an oxygen storage tank are all minimized, so as to save cost of the oxygen generator, reduce mounting area of the oxygen generator and mounting height of the absorption column to solve a problem of being limited by a space in mounting the oxygen generator.

Description

【Technical field】 [0001] The invention relates to a multiple adsorption tower device for an oxygen generator and an operation method thereof. 【Background technique】 [0002] Generally, an oxygen generator that generates oxygen by means of PSa (Pressure Swing adsorption: compression cycle adsorption) uses compressed air from an air compressor (air compressor) and introduces it through an air dryer (air dryer) and an air storage tank. Inside the adsorption tower. At this time, the nitrogen component in the compressed air will pass through the adsorbent (usually zeolite) filled in the adsorption tower for adsorption treatment, high-concentration separation and production of oxygen components that are not absorbed and absorbed. [0003] As mentioned above, the PSa mode oxygen generator usually adopts two adsorption towers. The reason is that when one adsorption tower introduces compressed air and produces oxygen, if the nitrogen in the adsorption tower is saturated, it will flo...
