An industrial and commercial MW-level transcritical carbon dioxide heat pump oil separator

Abstract

The invention discloses an industrial and commercial MW-grade transcritical carbon dioxide heat pump oil separator. The industrial and commercial MW-grade transcritical carbon dioxide heat pump oil separator comprises a shell and a liner; a support platform is arranged in the lower end of the shell, and divides the internal of the shell into an upper cavity and a lower cavity; an exhaust port and a communicating hole are formed in the support platform; an oil transmission pipe communicated with the lower cavity is arranged at the bottom of the shell; a lower flange is arranged at the top of the shell; an upper flange cover is tightly mounted on the lower flange; an intake port communicated with the upper cavity is formed in the side surface of the upper end of the shell; the lower end surface of the liner is tightly mounted on the upper surface of the support platform; the liner includes an inner layer and an outer layer; the outer layer coats the outer surface of the inner layer; the inner layer adopts a filter material; and the outer layer adopts an absorption material. The industrial and commercial MW-grade transcritical carbon dioxide heat pump oil separator is mounted between a compressor outlet and a gas cooler or between the gas cooler and a regenerator, realizes the return of frozen machine oil at the front end of a compressor, reduces the oil return time, and improves the return efficiency and the utilization rate of the machine oil.

Description

technical field [0001] The invention relates to the technology in the field of heat pump oil separators, in particular to an industrial and commercial MW-level transcritical carbon dioxide heat pump oil separator. Background technique [0002] Oil and gas separator is a kind of equipment used to separate oil and gas. It is used to separate impurities such as oil and other impurities condensed in compressed air, so that compressed air can be initially purified. It can be widely used in air compressors, air pumps and other equipment. However, the oil and gas separators in the prior art do not have effective separation in the range of 50-100°C and 3-10Mpa at the front end of the carbon dioxide transcriticality, and only have the ability to use in a low-pressure environment, usually with a pressure value of 0.1Mpa-2.5Mpa. Difficult to effectively separate CO at high pressure 50-100°C 2 Substances such as gas and refrigeration oil have brought inconvenience to use. Contents of...
