Efficient compression system for realizing air separation

Abstract

The invention provides an efficient compression system for realizing air separation, which comprises a gas compressor, an air inlet channel arranged at an air inlet of the gas compressor, and at least two air filtering devices communicated with the air inlet channel, and a control valve is arranged between each air filtering device and the air inlet. The air purifier further comprises a control device, a humidity detection device used for detecting environment humidity and a tiny dust detection device arranged on the air inlet channel, the control device is used for obtaining detection values of the humidity detection device and the tiny dust detection device so as to control opening and closing of the control valve, and replacement of the air filtering device can be directly controlled according to the content of tiny dust in the air inlet channel. According to the air compressor, dust is prevented from being excessively attached to blades of the air compressor, the influence that the compression efficiency is reduced due to the fact that the dust is attached to the blades can be reduced, the compression efficiency of the compression system is improved, the air filtering device does not need to be cleaned and shut down at the same time through the method of directly switching the air filtering device, and the compression efficiency is further improved.

Description

technical field [0001] The invention generally relates to the technical field of air separation, in particular to an efficient compression system for realizing air separation. Background technique [0002] Air separation is a device that uses air as the raw material, turns the air into a liquid state through the deep freezing method of the compression cycle, and then gradually separates it from the liquid air through rectification to produce inert gases such as oxygen, nitrogen, and argon. Air separation is a necessary procedure, and the efficiency of air compression is directly related to the efficiency of air separation. The air compression of existing air separation equipment needs to compress the air mainly through the air compressor. In order to ensure the cleanliness of the air, the air compression system It includes an air filter device, which is used to filter dust and sundries in the air, but the filter element of the existing air filter device is blocked after a lo...

[0002] Air separation is a device that uses air as the raw material, turns the air into a liquid state through the deep freezing method of the compression cycle, and then gradually separates it from the liquid air through rectification to produce inert gases such as oxygen, nitrogen, and argon. Air separation is a necessary procedure, and the efficiency of air compression is directly related to the efficiency of air separation. The air compression of existing air separation equipment needs to compress the air mainly through the air compressor. In order to ensure the cleanliness of the air, the air compression system It includes an air filter device, which is used to filter dust and sundries in the air, but the filter element of the existing air filter device is blocked after a long time of use, resulting in a large intake resistance and a decrease in compression efficiency. To solve this problem, the existing In the technology, a cleaning device for the air filter element will be added, and the operation of the cleaning device will be controlled by detecting the intake air volume. When the filter element is blocked and the intake air volume is insufficient, the cleaning device will work to clean the filter element. Clean up in time when it is clogged, but it still needs to be shut down during the cleaning process, and when the filter element is partially damaged, the air intake can meet the requirements, but a lot of dust will enter, and the dust will adhere to the compressor blades, resulting in a loss of compressor compression efficiency. reduce
