Problems solved by technology
However, during the operation of the refrigeration system, the lubricating oil will enter the entire refrigeration system together with the refrigerant vapor, which will increase the heat transfer resistance of the heat exchanger and reduce the heat exchange efficiency.
At the same time, due to the low temperature and pressure in the evaporator, especially in flooded evaporators, the lubricating oil will deposit at the bottom of the evaporator and cannot return to the compressor together with the refrigerant. When the lubricating oil cannot effectively return to the compressor When the machine is running, it will inevitably cause the oil volume in the compressor of the unit to continue to decrease, and eventually there will be vicious phenomena such as compressor oil shortage, shaft locking or even burning.
To solve the above problems, it is necessary to introduce a high-efficiency oil separator into the refrigeration device, but most of the commonly used oil separators are difficult to completely remove the lubricating oil
At this stage, the research on oil separators is mainly focused on structural changes. Many new oil separators are only improved from the structural level, so the more efficient the oil separator is, the higher the manufacturing cost is. The complexity of the

The invention discloses an electromagnetic oil separator. A refrigerant steam outlet is formed in the upper part of an oil separator shell; a lubricating oil outlet is formed in the bottom of the oil separator shell; an electromagnetic field generator is mounted in the oil separator shell; a two-phase mixture inlet is formed in the side wall of the oil separator shell; and two magnets are mounted in the electromagnetic field generator in parallel, and are respectively connected with the positive pole and the negative pole of a power supply. The electromagnetic oil separator is simple in total structure and obvious in oil-gas separation effect, prevents oil from entering a heat exchanger to influence the heat exchange efficiency of a condenser, and greatly improves the system efficiency.
Description
technical field [0001] The present invention relates to an oil separator, more specifically, relates to an electromagnetic oil separator. Background technique [0002] In compression refrigeration equipment, lubricating oil is an indispensable part of the compressor of the refrigeration system. It lubricates the mechanical moving parts of the compressor, reduces wear and tear, reduces the friction temperature of the mechanism, and enhances the sealing of the device. However, during the operation of the refrigeration system, the lubricating oil will enter the entire refrigeration system together with the refrigerant vapor, which will increase the heat transfer resistance of the heat exchanger and reduce the heat exchange efficiency. At the same time, due to the low temperature and pressure in the evaporator, especially in flooded evaporators, the lubricating oil will deposit at the bottom of the evaporator and cannot return to the compressor together with the refrigerant.
