Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of adsorption towers, in particular to a novel vertical high-efficiency axially distributed air extractor. Background Art
[0002] An adsorption tower is a device used for gas or liquid separation and purification. It usually consists of a tower body and fillers. The target component will be adsorbed on the surface of the filler, thereby being separated and purified. The adsorption process can utilize the difference in adsorption properties between substances, such as chemical adsorption, physical adsorption, etc. The existing adsorption tower distributors are mostly flat or spherical perforated plates, and the compressed air flow rate is fast and the impact force is large. It is easy to cause the molecular sieve in the adsorption tower to move and pulverize due to the impact force, which ultimately leads to huge economic losses. Utility Model Content
[0003] To achieve the above objectives, the utility model is implemented through the following technical solutions: a novel vertical high-efficiency axial distribution gas extractor, comprising: an adsorption tower body, wherein a vertical axial adsorption gas extraction structure is installed inside the adsorption tower body;
[0004] The vertical axial adsorption gas extraction structure includes: a partition baffle, an adsorption chamber, an air inlet chamber, an air inlet pipe, an axial gas extractor, a molecular sieve, a sealing top cover and an air outlet pipe;
[0005] The partition baffle is installed at a lower position inside the adsorption tower body, the adsorption chamber is opened above the partition baffle, the air inlet chamber is opened below the partition baffle, the air inlet pipe is installed on the air inlet of the lower wall of the adsorption tower body, the axial air extractor is embedded in the partition baffle, the axial air extractor is located in the adsorption chamber, the molecular sieve is filled in the adsorption chamber, the sealing top cover is installed at the top opening position of the adsorption tower body, and the air outlet pipe is embedded in the sealing top cover.
[0006] Preferably, support legs are provided on the adsorption tower body.
[0007] Preferably, the sealing top cover is mounted on the adsorption tower body by fixing bolts.
[0008] Preferably, a support base is provided on the support leg.
[0009] Preferably, connecting flanges are installed on the air inlet pipe and the air outlet pipe.
[0010] Beneficial Effects
[0011] The utility model provides a novel vertical high-efficiency axial distribution air extractor, which has the following beneficial effects: this scheme uses a vertical axial adsorption air extraction structure, which changes the gas flow direction and flow rate, increases the airflow contact area, improves the molecular sieve adsorption rate, and reduces the economic loss caused by the pulverization of the molecular sieve. At the same time, due to the stable airflow, the molecular sieve clamping device can be eliminated, reducing the production cost. Since a vertical axial distributor is used, the dead space of the non-adsorbable part of the tower body is reduced, the airflow distribution in the tower body is improved, thereby improving the utilization rate of the molecular sieve, greatly extending the service life of the molecular sieve, improving the operating indicators of the equipment, and reducing energy consumption. It solves the problem that the existing adsorption tower distributors are mostly flat plates or spherical orifice plates, the compressed air flow rate is fast, the impact force is large, and it is easy to cause the molecular sieve in the adsorption tower to be displaced and pulverized due to the impact force, which ultimately brings huge economic losses.

DETAILED DESCRIPTION
[0015] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
[0016] Example: See Figure 1-2 When using the vertical axial adsorption and air extraction structure, the external air supply pipeline is connected to the air inlet pipe 5 installed on the lower wall of the adsorption tower body 1, and the gas to be adsorbed is transported to the inside of the adsorption tower body 1. After the gas enters the air inlet chamber 4, the gas is forced to enter the adsorption chamber 3 through the axial air extractor 6 by air pressure, so that the gas is discharged from the side, which changes the gas flow direction and flow rate. The molecular sieve 7 filled in the adsorption chamber 3 is used for separation and adsorption, which increases the airflow contact area, improves the adsorption rate of the molecular sieve 7, and prevents the molecular sieve 7 from being displaced and pulverized due to the impact force of the gas. After the adsorption separation is completed, the gas is discharged through the air outlet pipe 9 installed on the top sealing cover 8.
