specific Embodiment

[0030] The core equipment of the refrigerant discharge evaporation system is a partitioned heat exchange evaporator. The liquid refrigerant separated from the separator at the inlet of each compressor section is sent to the evaporator, heated and vaporized by the heat medium, and then sent to the inlet of the first compressor section.

[0031] The refrigerant is propylene. The gaseous propylene from the low-temperature methanol washing unit enters the first stage of the compressor after the entrained liquid propylene is separated by the first-stage inlet separator. The compressed gaseous propylene is condensed into liquid propylene by the circulating water through the outlet cooler and condenser, sent to the propylene buffer tank, and then decompressed into the propylene flash tank. The gaseous propylene flashed in the propylene flash tank enters the third-stage inlet of the compressor after separating the entrained liquid propylene in the three-stage inlet separator. The liq...

Abstract

The invention discloses an energy-saving compression refrigeration method. The optimized design of the anti-surge circuit after the gaseous refrigerant is compressed and cooled in three stages ensures low power consumption of the compressor, and the refrigerant storage tank is incorporated into the compression refrigeration system to improve compression refrigeration. The stability of the circuit, the refrigerant evaporative emission system greatly improves the convenience of operation compared with the traditional power transmission method.

Description

technical field [0001] The invention relates to the technical field of compression refrigeration, in particular to an energy-saving compression refrigeration method. Background technique [0002] In the chemical industry, gaseous refrigerant pressurization, condensation and throttling refrigeration technology mostly provide the necessary cold environment for units such as low-temperature methanol washing, low-temperature oil washing, ammonia synthesis and liquid ammonia separation. In traditional industrial production, two-stage compression refrigeration is often used. The gaseous refrigerant flashed at the shell side of the subcooler is merged into the gaseous refrigerant flashed by the cooling user and then sent to the first stage inlet of the compressor; the anti-surge circuit of the compressor is derived from the compressor The outlet of the compressor; the condensed liquid refrigerant gravity flows to the pressure reducing valve to decompress and then flashes; the liqui...
