[0002] Ethylene glycol is an important basic chemical raw material in the textile industry. The purity of ethylene glycol is very high. The ethylene glycol distillation unit that guarantees the quality of ethylene glycol needs to consume a large amount of steam. In recent years, variable speed drive (VSD) technology has been developed to improve the efficiency of steam compressors, especially, and compressors are now generally designed with VSD capabilities. Such compressors can be called "variable speed compressors" and can efficiently match the compression requirements of the system in which the compressor is deployed.

[0003] However, in the prior art, during the use of steam compressors for ethylene glycol production, ethylene glycol as a medium is heated and evaporated in the production process to form steam, and the steam is then sent to the steam compressor for compression to increase its pressure and temperature. However, ethylene glycol steam is mostly acidic steam, which is easy to form thick scale inside the compressor, and the formed moisture will also accumulate and become scale. Although the existing compressors are equipped with a filter structure at the inlet pipe end to filter the acidic steam to avoid scaling, long-term use with a large flow rate will still cause blockage inside the compressor, resulting in the use status, efficiency and life of the compressor being affected.

[0037] The airtightness detection sensors form multiple groups of airtight connection ends installed at the compression regulating component 1, which are used to monitor the airtightness during the compression operation in real time, and respond and feedback to the compression operation dynamic impurity removal component 2 in time, so that the compression operation dynamic impurity removal component 2 can perform airtightness correction operations without interfering or affecting the operation of the compression regulating component 1 while the compression operation is not stopped.

[0038] The compression control component 1 includes:

[0039] The compression integrated detection structure 101, the liquid level warning processing structure, the main compressor body, the first secondary compressor body 108 and the second secondary compressor body 1091, the side ends of the main compressor body are connected to the adapting gas guide pipeline 1095, the side ends of the adapting gas guide pipeline 1095 are connected to the counterflow cooler 107, the side ends of the counterflow cooler 107 are connected to the separator 1093, and the side ends of the separator 1093 are respectively connected to the gas guide chambers of the first secondary compressor body 108 and the second secondary compressor body 1091 The control valve is connected, and the main compressor body, the first secondary compressor body 108 and the second secondary compressor body 1091 form a multi-stage compression structure through the matching gas guide pipeline 1095, the countercurrent cooler 107, and the separator 1093. A variable frequency motor is installed on the bottom side of the main compressor body, and a variable frequency structure 1096 is installed on the sides of the first secondary compressor body 108 and the second secondary compressor body 1091. The variable frequency motor and the variable frequency structure 1096 are both signal connected through an external sequential controller.

[0040] The side end of the compression integrated detection structure 101 is connected to a liquid level electromagnetic detection air inlet pipe 105 , the top of the liquid level electromagnetic detection air inlet pipe 105 is connected to a nanofiltration membrane structure 104 through a quick connection flange, and the top of the nanofiltration membrane structure 104 is connected to an air inlet pipe 103 .
