Description

Technical Field

[0001] The utility model relates to the technical field of adsorption dryer equipment, in particular to an easily detachable air adsorption tower used for an adsorption dryer. Background Art

[0002] The adsorption dryer uses advanced chemical technology. Its principle is to use the difference in volume between water and air molecules to filter out saturated water vapor in the compressed air using a gas purification-specific molecular sieve. The water molecules can be easily adsorbed in the molecular sieve particles, and then the molecular sieve can be restored using a regeneration method. The dew point of the compressed air can easily reach -40°C.

[0003] Adsorption dryers achieve drying effects through "pressure changes" (pressure swing adsorption principle). Since the air's ability to hold water vapor is inversely proportional to pressure, a portion of the air after drying (called regeneration gas) is decompressed and expanded to atmospheric pressure. This pressure change makes the expanded air drier, and then it is allowed to flow through the desiccant layer that needs to be regenerated and is not connected to the air flow (that is, the drying tower that has absorbed enough water vapor). The dry regeneration gas absorbs the moisture in the desiccant and takes it out of the dryer to achieve the purpose of dehumidification. The two towers work in a cycle without the need for a heat source, and continuously provide dry compressed air to the user's gas system.

[0004] The prior art has the following defects or problems: in the “adsorption tower of compressed air dryer” with publication number CN201768481U in the prior art, “an exhaust port is arranged at the top of the tower body, an air inlet is arranged at the middle of the tower body, and is connected to the air cavity at the bottom of the tower body through an air inlet pipe, a mesh partition is arranged inside the adsorption tower to separate the inside of the tower body into a bottom air cavity and an upper adsorbent cavity, and a regeneration gas exhaust port and a sewage outlet are arranged at the bottom of the air cavity”;

[0005] During use, the above-mentioned device sets a mesh partition inside the adsorption tower to form a bottom air cavity, so that the compressed air can be evenly distributed and pass through the adsorbent layer slowly, improving the efficiency of adsorption and avoiding airflow short circuit; at the same time, the air pressure drop at the inlet and outlet is small. When the utility model is working, the supersaturated water and impurities can fall to the bottom of the air and deposit, and are flushed out of the sewage outlet under the air pressure during reverse regeneration, and are cleaned thoroughly, avoiding the problems of the bottom adsorbent failing due to the deposited water and the clogging of the lower diffuser by tiny impurity particles, and also greatly prolonging the service life of the adsorbent.

[0006] The above content adopts an integrated structure, which cannot be disassembled, and the adsorption liquid residue inside the cavity cannot be cleaned. At the same time, the adsorption process is single and does not have secondary treatment, so the adsorption effect is poor. Utility Model Content

[0036] The working principle and use process of the utility model are as follows: the operator introduces the gas to be adsorbed into the adsorption chamber 101 through the diffuser 601 through the air inlet end 6, and performs preliminary filtration on the gas through the internal filter screen 502. The impurities after filtration remain at the bottom of the filter screen 502, and the sewage or granular residues generated at the same time will be discharged through the discharge end 8. Then the gas enters the second-level adsorption cylinder 2 through the air guide pipe 4. The second-level adsorption cylinder 2 introduces adsorption liquid into the liquid chamber 201 through the liquid inlet end 11, and the gas is adsorbed twice by the adsorption liquid. Then the adsorbed gas is discharged through the exhaust end 10, and the adsorbed liquid after adsorption is discharged through the liquid discharge end 1 2 can be discharged. When the operation of the adsorption tower is completed, when it is necessary to clean the adsorption liquid remaining in the secondary adsorption cylinder 2, it is only necessary to disassemble the first cylinder shell 203 and the second cylinder shell 204 to complete the disassembly of the secondary adsorption cylinder 2, so as to avoid the adsorption liquid remaining in the liquid containing cavity 201 and affecting its normal use. At the same time, the adsorption efficiency of the adsorption tower is further improved.
