AI Technical Summary
Existing temperature-controlled adsorption gas drying devices require additional heating to remove the adsorption medium when the adsorbent is saturated and needs regeneration, resulting in product gas loss, reduced efficiency, and increased costs.
A variable temperature adsorption gas drying device is designed, including drying tower one and drying tower two. Through the combination of water separator, cooler and circulating fan, the adsorbent is regenerated efficiently and the product gas is recovered without loss.
This achieves zero product gas loss during the drying process, improving efficiency and reducing costs, thus achieving the goal of cost reduction and efficiency improvement.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of temperature-switching adsorption technology, and in particular relates to a temperature-switching adsorption gas drying device. Background Technology
[0002] Air drying removes moisture from the air and comes in two main forms: adsorption and refrigeration. Adsorption compressed air dryers utilize the principle of pressure swing adsorption; when humid air passes through an adsorbent, the moisture is adsorbed, resulting in dry air. Refrigeration compressed air dryers utilize the principle of cooling the air, lowering its temperature, and condensing the moisture from the humid air to obtain dry air.
[0003] In the existing technology, in the field of temperature-controlled adsorption gas drying, the adsorbent needs to be regenerated after it becomes saturated. Regeneration requires additional heated gas to remove the adsorption medium such as water adsorbed by the adsorbent, so that the adsorbent can be regenerated and reused. At the same time, the product gas will be lost. Utility Model Content
[0004] The purpose of this invention is to provide a temperature-switching adsorption gas drying device, which solves the existing problems through the design of temperature-switching adsorption.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a temperature-switching adsorption gas drying device, including a drying tower one and a drying tower two. The input ends of the drying tower one and the drying tower two are equipped with water separators. The drying tower one and the drying tower two are interconnected. The output end of the drying tower two is equipped with a cooler. One end of the cooler is equipped with a water separator two. The output end of the water separator two is equipped with a separation port.
[0007] Furthermore, an exhaust port is provided at one end of the water separator, and a separator is provided inside the exhaust port.
[0008] Furthermore, a circulating cooling water main is provided at one input end and one output end of the cooler.
[0009] Furthermore, multiple programmable valves are installed at the input and output ends of the drying tower one and drying tower two.
[0010] Furthermore, a circulating fan is installed between the second drying tower and the cooler.
[0011] This utility model has the following beneficial effects:
[0012] 1. This utility model aims to ensure that high-value-added gaseous products are dried without any loss. Conventional drying equipment typically results in a loss of approximately 5%-10% of the product gas. This application aims to avoid this 5%-10% product loss, thereby reducing costs and increasing efficiency.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A water separator V301 is provided at the input end of the drying tower T303A and the drying tower T303B. The drying tower T303A and the drying tower T303B are interconnected. A cooler E303 is provided at the output end of the drying tower T303B. A water separator V302 is provided at one end of the cooler E303. A separation port is provided at the output end of the water separator V302.
[0020] The water separator V301 has an exhaust port at one end of its output, and a separator is installed inside the exhaust port.

[0024] A specific application of this embodiment is as follows: First, water is separated by water separator V301. The condensate is then discharged to the outside through water separator V301, while the remaining water is discharged into drying towers T303A and T303B through connecting pipes for drying. At this time, the water dried by drying towers T303A and T303B will enter cooler E303 through connecting pipes for cooling. Meanwhile, circulating fan T303C continuously draws water from cooler E303. A portion of the water in cooler E303 is cooled and drawn into water separator V302, and the condensate is discharged to the outside again. The other portion of the water in cooler E303 will be returned for reprocessing through the circulating cooling water main pipe.
