Description

Technical Field

[0001] The utility model relates to the technical field of adsorption type compressed air dryers, in particular to an adsorption type compressed air dryer. Background Art

[0002] The compressed air adsorption dryer achieves the drying effect through "pressure change" (pressure swing adsorption principle). Since the air's ability to hold water vapor is inversely proportional to the pressure, a portion of the dried air (called regenerated 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 airflow (that is, the drying tower that has absorbed enough water vapor). The dry regenerated 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, continuously providing dry compressed air to the user's gas system.

[0003] After searching, a Chinese patent discloses an adsorption compressed air dryer with a built-in filter tube (authorization announcement number CN207641252U), including two groups of compressors, an air duct is installed on the compressor, two groups of filter tubes are installed on the air duct, four groups of air valves are installed on the air duct, adsorption towers are connected to the left and right sides of the air duct, an air outlet pipe is installed on the top of the adsorption tower, two groups of one-way valves are installed on the air outlet pipe, a control box is installed between the two groups of adsorption towers, and an air inlet is installed on the left side of the outer tube wall. Although this patented technology can filter out particles with larger diameters in the air and retain them in the filter tube by installing a filter tube at the air outlet end of the compressor, and clean the filtered sediment in the filter tube at the corresponding position when replacing the adsorption tower, it avoids the blockage of the air duct affecting the air drying effect.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that, in addition to particles with larger diameters, the floating objects in the air also include some floating hair, plastic skin, etc. After these things enter the gypsum filter net inside the filter, they will block the mesh of the gypsum filter net, causing poor air intake, thereby reducing the effect of air drying and compression.

[0015] By adopting the technical solution, the fixing hoop and the bolt are used in coordination, so that the dust collecting bag can be easily disassembled and installed.

[0016] As a preferred embodiment, an air outlet pipe is fixedly connected between the tops of the two adsorption towers, a control box is arranged between the two adsorption towers, and two air valves are fixedly installed inside the air inlet pipe.
