Molecular sieve adsorption tower structure of oxygenerator

Abstract

The invention discloses a molecular sieve adsorption tower structure of an oxygenerator. The molecular sieve adsorption tower structure comprises an electromagnetic valve, wherein an upper cover is arranged on one side of the electromagnetic valve; an adsorption tower body is arranged at the bottom of the upper cover; a lower cover is arranged at the bottom of the adsorption tower body; a deoxygenation threaded hole and a pressure regulating valve are formed / arranged in / on the upper cover; pressure regulating holes are formed in the lower cover; an air inlet is formed in one side of each pressure regulating hole; a denitrogenation hole is formed in the other side of each pressure regulating hole; an oxygen outlet is formed in one side of each air inlet and communicates with the corresponding air inlet hole; the two pressure regulating holes are corresponding arranged and communicate with each other; molecular sieve tubes are arranged inside the adsorption tower body; an oxygen storingtank and a nitrogen transporting tank are arranged between the molecular sieve tubes; a spring is arranged inside each of the two molecular sieve tubes; and a filter screen and filter cotton are arranged at the bottom of each spring. In addition, silencing in the whole process is realized, the cost is reduced and the design is compact and reasonable.

Description

technical field [0001] The invention relates to a molecular sieve adsorption tower structure, in particular to an oxygen generator molecular sieve adsorption tower structure. Background technique [0002] Molecular sieves are crystalline silicates or aluminosilicates, which are formed by connecting silicon-oxygen tetrahedrons or aluminum-oxygen tetrahedrons through oxygen bridges. [0003] The pore and cavity system with molecular size (usually 0.3~2.0 nm) has the characteristics of sieving molecules. However, with the in-depth research on the synthesis and application of molecular sieves, researchers have discovered aluminophosphate molecular sieves, and the framework elements (silicon or aluminum or phosphorus) of molecular sieves can also be composed of B, Ga, Fe, Cr, Ge, Ti, V , Mn, Co, Zn, Be and Cu, etc., and the size of the pores and cavities can reach more than 2 nm. Therefore, molecular sieves can be divided into silicon-aluminum molecular sieves, phosphorus-alumin...
