Description

Technical Field

[0001] This utility model relates to the field of dryers, specifically a low-pressure, high-efficiency, and energy-saving dryer. Background Technology

[0002] A dryer is a device used to remove moisture from materials and is widely used in industries such as manufacturing, agriculture, food processing, and chemicals. Dryers can be classified into various types based on their working principles and application scenarios. However, existing low-pressure dryers suffer from high energy consumption due to the inability of the heat-absorbing liquid to achieve balanced heat exchange caused by the extremely high temperature of the compressed gas. Therefore, this paper proposes a low-pressure, high-efficiency, and energy-saving dryer to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a low-pressure, high-efficiency, and energy-saving dryer to solve the above-mentioned problems.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a low-pressure, high-efficiency, and energy-saving dryer, comprising a drying heat exchanger and an atmospheric pressure heat exchanger, wherein the output port of the drying heat exchanger is connected to the input port of the atmospheric pressure heat exchanger, and the atmospheric pressure heat exchanger is provided with an air inlet and an air outlet, wherein the air inlet is connected to an air-driven output device, and the atmospheric pressure heat exchanger provides cooling compensation to the drying heat exchanger.

[0005] Preferably, the output port of the atmospheric pressure heat exchanger is sequentially connected to a first water-gas separation filter and a second water-gas separation filter.

[0006] Preferably, the second water-gas separator is provided with a dry gas outlet.

[0007] Preferably, the dryer heat exchanger is provided with an outlet and an inlet at both ends.

[0008] Preferably, high-temperature compressed gas is introduced into the drying heat exchanger through a high-temperature compressed gas inlet.

[0009] Preferably, the air entering the atmospheric pressure heat exchanger is atmospheric pressure low-temperature air.

[0010] Compared with the prior art, the advantages of this utility model are: the low-temperature air at atmospheric pressure entering through the atmospheric pressure heat exchanger can compensate for the shortcomings of the heat exchanger in which the heat-absorbing liquid cannot balance the heat exchange due to the extremely high temperature of the high-temperature compressed gas. Moreover, the use of low-temperature air at atmospheric pressure greatly reduces energy consumption, especially in cold winter weather, and makes the drying of high-temperature compressed air more efficient and faster.

[0017] Please see Figure 1-2As shown, a low-pressure, high-efficiency, and energy-saving dryer includes a drying heat exchanger 1 and an atmospheric pressure heat exchanger 2. The output port of the drying heat exchanger 1 is connected to the input port of the atmospheric pressure heat exchanger 2. The atmospheric pressure heat exchanger 2 is provided with an air inlet 21 and an air outlet 22, and the air inlet 21 is connected to an air-driven output device. The atmospheric pressure heat exchanger 2 provides cooling compensation for the drying heat exchanger 1. The output port of the atmospheric pressure heat exchanger 2 is sequentially connected to a first water-gas separation filter 4 and a second water-gas separation filter 5. The second water-gas separation filter 5 is provided with a dry gas outlet 51.

[0018] The drying heat exchanger 1 is provided with an outlet 11 and an inlet 12 at both ends, and high-temperature compressed gas is introduced into the drying heat exchanger 1 through a high-temperature compressed gas inlet 13.

[0019] The air entering the atmospheric pressure heat exchanger 2 is atmospheric pressure low temperature air.

[0020] An electrical control box 3 is installed on the drying heat exchanger 1.

[0021] Compared with existing technologies, the difference is that the low-temperature air entering through the low-temperature air exchanger 22 can compensate for the shortcomings of the heat exchanger 1, where the heat-absorbing liquid cannot balance the heat exchange due to the extremely high temperature of the high-temperature compressed gas. Moreover, the use of low-temperature air at low temperature greatly reduces energy consumption, especially in cold winter weather, and makes the drying of high-temperature compressed air more efficient and faster.
