Problems solved by technology

At present, the adsorption towers on the market are filled with molecular sieves in the tower, and the structure is relatively simple, but there are deficiencies in the process of oxygen production, such as insufficient contact between air and molecular sieves due to the straight-line circulation of air entering the tower. First, the utilization rate of molecular sieves is reduced. , The second is that the oxygen content is low; if the molecular sieve is impacted by the air for a long time, the gap becomes larger and the powder clogs the pipeline, which affects the oxygen production process, etc.

Abstract

The invention discloses a molecular sieve adsorption column used in oxygen production equipment. The molecular sieve adsorption column includes an adsorption column body, and a gas inlet and a gas outlet which are respectively formed in the bottom end and the top end of the adsorption column main body; a molecular sieve filter is mounted in the adsorption column main body; the molecular sieve filter comprises a plurality of cylindrical molecular sieve filtering layers which are coaxially arranged in sequence from inside to outside, a seat plate and a cover plate; the bottom ends of the molecular sieve filtering layers are installed on the seat plate, the top ends of the molecular sieve filtering layers are installed on the cover plate, a gas collecting cavity is formed between every two adjacent molecular sieve filtering layers, an inner cavity is defined by the molecular sieve filtering layer on the innermost layer, and the inner cavity is communicated with a gas outlet. A plurality of molecular sieve filtering layers are arranged, so that air can be in full contact with the molecular sieves, the filtering area and the contact area are effectively increased, the molecular sieve filtering layers and the gas collecting cavity are matched in a circulating mode, a good separating and filtering effect is achieved, and the separating and filtering efficiency and the oxygen content in gas are improved.

Description

technical field [0001] The invention relates to a molecular sieve adsorption tower used in oxygen-generating equipment, and belongs to the technical field of oxygen-generating. Background technique [0002] With the improvement of people's living standards and awareness of disease prevention, oxygen health care and oxygen therapy are being used more and more widely as an effective means to enhance physical fitness and prevent diseases. The working principle of the oxygen production equipment is to use the pressure swing adsorption technology to separate oxygen and nitrogen from the compressed air by using the high pressure adsorption and low pressure desorption characteristics of molecular sieve for nitrogen. [0003] As an important component of oxygen production technology, adsorption tower's function and structure directly affect the efficiency of oxygen production. At present, the adsorption tower on the market is to fill the molecular sieve into the tower, and the stru...
