Description

Technical Field

[0001] This utility model belongs to the technical field of industrial oxygen production equipment, specifically relating to a multi-channel airflow diversion adsorption tower. Background Technology

[0002] The airflow split adsorption tower is one of the core components of an industrial oxygen generator, primarily used to separate oxygen from the air through physical adsorption technology. Industrial oxygen generators, which use compressed air and adsorption materials such as molecular sieves to enrich oxygen, are widely used in metallurgy, chemical industry, and other fields. In existing industrial oxygen production, the adsorption tower is a key piece of equipment for oxygen separation and purification. Traditional adsorption towers suffer from several problems in airflow distribution, such as uneven distribution leading to low adsorbent utilization, premature saturation of some adsorbents, and insufficient utilization of others, thus affecting the overall efficiency of the tower. Furthermore, the airflow switching during adsorption and desorption is not smooth enough, easily impacting the adsorbent, shortening its lifespan, and increasing oxygen production costs. In addition, the complex overall structure of existing industrial oxygen generators, coupled with inconvenient maintenance and repair, limits their application in large-scale industrial production. Therefore, we propose a multi-channel airflow split adsorption tower. Utility Model Content

[0003] The purpose of this invention is to provide a multi-channel airflow diversion adsorption tower to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel airflow diversion adsorption tower, comprising a tower body and an air compressor, wherein multiple adsorption units are provided inside the tower body, and an air inlet main pipe is provided at one end of the tower body. The air inlet main pipe is located at the inner end of the tower body and is connected to multiple diversion channels. The diversion channels are connected to the adsorption units, and a flow regulating valve is installed on one side of each diversion channel. An air outlet main pipe is connected to the upper side of the tower body and is connected to the upper air outlet of the adsorption unit.

[0005] Preferably, the diversion channels are radially and evenly distributed at the end of the intake manifold, and the inner diameter of each diversion channel is the same.

[0006] Preferably, the adsorption unit has a cylindrical structure and the adsorbent is a zeolite molecular sieve.

[0007] Preferably, a cooler is provided on one side of the air compressor, a dust collector is provided on one side of the cooler, and a dryer is provided on one side of the dust collector. The air compressor, cooler, dust collector, and dryer are all connected by connecting pipes, and the dryer is connected to the tower body by an air inlet main pipe.

[0008] Preferably, an oxygen buffer tank is connected to the end of the main exhaust pipe on one side of the tower body.

[0009] Preferably, the upper sides of the tower are symmetrically connected with a regenerated gas inlet and a regenerated gas outlet.

[0010] Compared with the prior art, the beneficial effects of this utility model are: The multi-channel airflow distribution design allows air to be evenly distributed to each adsorption unit, improving the utilization rate of the adsorbent and thus increasing the overall adsorption efficiency of the adsorption tower. The smooth airflow switching reduces the impact on the adsorbent, reduces adsorbent wear and breakage, and effectively extends the service life of the adsorbent. The uniform airflow distribution and stable adsorption and desorption process are conducive to improving the oxygen separation effect and ensuring the stable quality of the produced oxygen.

[0014] Please see Figure 1-3 This utility model provides a technical solution: a multi-channel airflow diversion adsorption tower, including a tower body 1 and an air compressor 2.

The air inlet main pipe 7 is located at the inner end of the tower body 1 and is connected to multiple diversion channels 8. The diversion channels 8 are connected to the adsorption units 10. A flow regulating valve 9 is installed on one side of each diversion channel 8. The upper side of the tower body 1 is connected to an air outlet main pipe 11, which is connected to the upper air outlet of the adsorption unit 10.

[0015] Specifically, the diversion channels 8 are radially and evenly distributed at the end of the intake manifold 7, and the inner diameter of each diversion channel 8 is the same.
