Description

technical field [0001] The invention relates to the structural field of an oil separator for air-conditioning and refrigeration system accessories, in particular to a horizontal oil separator, and in particular to an engine oil antifreeze separation device. Background technique [0002] At present, in the refrigeration system, when the compressor is working, a small amount of refrigerated oil must be continuously pressed out together with the refrigerant and enter the pipeline of the refrigerating system, condenser and evaporator. When the refrigerated oil cannot be continuously When returning to the compressor, the oil level of the compressor will drop, and when the refrigerating oil is exhausted, the compressor will burn due to lack of oil. Therefore, it is one of the most important issues in the design of the refrigerating system to ensure that the refrigerating oil is continuously returned to the compressor.

[0002] At present, in the refrigeration system, when the compressor is working, a small amount of refrigerated oil must be continuously pressed out together with the refrigerant and enter the pipeline of the refrigerating system, condenser and evaporator. When the refrigerated oil cannot be continuously When returning to the compressor, the oil level of the compressor will drop, and when the refrigerating oil is exhausted, the compressor will burn due to lack of oil. Therefore, it is one of the most important issues in the design of the refrigerating system to ensure that the refrigerating oil is continuously returned to the compressor. The small amount of refrigerating oil entering the system can improve the cooling efficiency of the unit and ensure the safe and reliable operation of the unit. In order to reduce the refrigerating oil entering the heat exchanger and ensure the stable and safe operation of the compressor, oil The oil return system is composed of separator, oil storage tank, oil level controller and other components. The oil separator is installed between the exhaust pipeline of the compressor and the condenser as an important component, and its function is to discharge the oil together with the exhaust gas. The refrigerated oil is separated and directed to the compressor. Common oil separation methods include filtration, washing, centrifugation, and deceleration. Although the structures of oil separators are different, the separation is one or more of the above. Combination of separation methods. At present, for large-scale oil separators, two separation methods are mainly used: centrifugal and filtration. Centrifugal oil separation has a large resistance and is suitable for separating large-diameter oil droplets, while the filter type has a large volume and is suitable for separating small-diameter oil. In addition, in the practical process, the distribution of the refrigerant oil and refrigerant gas mixture into and out of the oil separator is uneven, resulting in the high flow rate of the mixed gas in some areas, which affects the separation effect, while some other patents of centrifugal oil separators A filter layer is also set up, but usually its volume is small and the cross-sectional flow velocity is high, which only plays the role of stabilizing the airflow and controlling the flow direction of the gas, and its ability to separate small-diameter oil droplets is very limited
