Abstract

The invention discloses an industrial critical carbon dioxide heat pump oil separator. The industrial critical carbon dioxide heat pump oil separator comprises a main cylinder; an inner cylinder is arranged inside the main cylinder; an oil inlet connecting pipe communicates with the top end of the inner cylinder; a gas exhaust pipe communicates with the surface of the main cylinder; the surface of the inner cylinder is not in contact with the inside of the main cylinder; a first filter screen and a second filter screen are respectively arranged inside the inner cylinder; and a positioning plate is embedded inside the inner cylinder. According to the industrial critical carbon dioxide heat pump oil separator, the inner cylinder is arranged inside the main cylinder, through holes are formed in the surface of the inner cylinder, thus lubricating oil can flow out through the through holes, and the oil separator can finish independent exhaust when one of the first filter screen, the second filter screen or a third filter screen is blocked, so that the condition that the lubricating oil flows back is avoided, the damage of the lubricating oil return to a critical carbon dioxide heat pump is reduced, and the situation that the critical carbon dioxide heat pump cannot operate normally is avoided.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to an industrial critical carbon dioxide heat pump oil separator. Background technique [0002] The function of the oil separator is to discharge the gas in the lubricating oil to ensure the safe and efficient normal operation of the critical carbon dioxide heat pump. [0003] The working principle of the filter oil separator used in critical carbon dioxide heat pumps today is that lubricating oil enters the oil separator, and the lubricating oil is filtered and separated through the filter on the top of the oil separator. After separation, the gas will separate from the lubricating oil. The filtered lubricating oil will enter the critical carbon dioxide heat pump through the return pipe, but today's oil separators only filter and separate the lubricating oil through the top filter, the separation effect is poor, and the dripping lubricating oil will exist after filteri...
