Description

Technical Field

[0001] The utility model relates to the technical field of compressor dryers, in particular to a single-screw natural gas compressor dryer. Background Art

[0002] The compressor dryer is used to dry the natural gas produced by the single-screw natural gas compressor and remove moisture from the natural gas. The compressor dryer consists of a box, an air inlet pipe, an evaporator, an air outlet pipe, a connecting pipe one, a compressor, a connecting pipe two, a fan, a mounting plate, a condenser, a connecting pipe three, a shut-off valve and a connecting pipe four. When the single-screw natural gas compressor compresses the natural gas, it enters the evaporator through the air inlet pipe on the box to form a heat exchange with the refrigerant inside, and is dried to remove moisture. After the finished compressed natural gas is obtained, it is discharged from the air outlet pipe. The refrigerant is compressed into a high-temperature and high-pressure gas by the compressor, and then transported to the condenser through the connecting pipe two, making the surface of the connecting pipe two very hot. The fan on the mounting plate is started to cool the condenser, and then it is transported to the shut-off valve through the connecting pipe three. After passing through the shut-off valve, it becomes a low-temperature and low-pressure refrigerant, and then enters the evaporator through the connecting pipe four to exchange heat with the compressed natural gas. The refrigerant after the heat exchange becomes gaseous and is transported to the compressor through the connecting pipe one to form a cycle.
