Description

Technical Field

[0001] The utility model relates to the technical field of gas compressors, in particular to a gas compressor with a heat recovery structure. Background Art

[0002] Gas compressors are also called air compressors. Most air compressors are reciprocating piston type. The air entering the compressor through the air inlet is compressed by piston movement to form a high temperature and high pressure state, and then discharged through the exhaust port. In most liquefaction plants, the gas needs to be pressurized by a gas compressor first, and then the high temperature and high pressure gas is converted into a low temperature and high pressure liquid through the cooling structure on the rear side and stored in a storage tank. The heat released will be transported to the factory through a transportation pipeline for secondary utilization at the hot spot. This improves the utilization rate of energy and avoids energy waste and dangerous high temperatures around the machine body. However, during the gas transportation process, the gas temperature is the highest, especially in the transportation pipeline connected to the gas compressor cylinder. Before being transported to the cooling structure, a large amount of heat will be lost due to contact with the outside air, which reduces the energy utilization rate.

[0003] Most of the existing heat recovery structures only have a water cooling structure inside, which uses cooling water to cool down the high temperature at the cylinder connection, and connects the cooling water to the cooling structure on the rear side through the drain port, and is recovered through the cooling structure for secondary use. However, the heat recovery structure is fixedly installed on the gas compressor during use. When the length of the pipeline connected to the cooling structure changes, it is necessary to replace the new gas compressor or disassemble and replace the heat recovery structure during installation, which reduces the installation efficiency and makes the applicability of the heat recovery structure worse. After the heat exchange tube has been used for a period of time, scale will form on the outer surface of the heat exchange tube, which will reduce the heat exchange efficiency. When cleaning, the heat exchange structure needs to be disassembled before cleaning. The heat exchange structure is mostly fixedly connected to the heat exchange tube, which makes cleaning difficult. Therefore, we propose a gas compressor with a heat recovery structure to solve the above problems. Utility Model Content
