Novel vertical type oil-gas separator

Abstract

The invention discloses a novel vertical type oil-gas separator. Oil-gas mixtures enter the oil-gas separator through a bending pipeline, centrifugal separation is formed in the bending pipeline, the oil-gas mixtures form collision separation with the wall surface of a horizontal barrel body after coming out from the bending pipeline, the oil-gas mixtures reversely flow after being collided, after the oil-gas mixtures penetrate through a W-shaped baffling perforated plate and a vertical perforated plate, part of oil drops are caught by the wall surfaces of the baffling perforated plate and the vertical perforated plate, and the oil-gas mixtures pass through a filter screen at uniform flow velocity to be filtered and separated so that the surplus oil drops are separated out. Multiple stages of separating devices are utilized to separate the oil drops out from the oil-gas mixtures, the separating efficiency is not affected by the machine set running state, and on the premise that the separating efficiency is met when a machine set is run at full load, the separating efficiency under other load is also very good; the oil-gas mixtures are very small in resistance loss through collision and filter screen separation; filling of lubricating oil is mainly located on a vertical barrel body section, and the filling volume of the lubricating oil is reduced.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a novel vertical oil-gas separator. Background technique [0002] The oil-air separator is one of the key components in the refrigeration system. A high-quality oil-air separator can not only ensure the high-efficiency operation of the compressor, but also avoid the influence of lubricating oil on the heat transfer performance of the heat exchanger of the unit, and improve the efficiency of the refrigeration unit. performance. At present, the oil-gas separators used in the refrigeration industry mainly have three types in shape: vertical, horizontal and spherical. Among them, the vertical oil separation represented by the cyclone separator mainly throws the oil droplets in the oil-gas mixture to the wall of the cylinder under the action of centrifugal force, so as to realize the separation of oil and gas. The separation efficiency of the cyclone oil-gas separator is high, but it is limi...

Problems solved by technology

Among them, the vertical oil separation represented by the cyclone separator mainly throws the oil droplets in the oil-gas mixture to the wall of the cylinder under the action of centrifugal force, so as to realize the separation of oil and gas. The separation efficiency of the cyclone oil-gas separator is high, but it is limited by the cylinder. The external dimensions have a great influence, especially the influence of the inlet mixture flow rate. Generally, the separation efficiency is directly proportional to the inlet flow rate. That is to say, when the unit is operating under partial load, the separation efficiency of the cyclone separator will decrease; Due to the high inlet flow velocity and large resistance loss, it has a certain impact on the operating efficiency of the unit

The horizontal oil separator with the filter screen as the main separation element can meet the oil-gas separation requirements of the unit under different working conditions, and the resistance loss is small at the same time, but it is too large and needs to be filled with a large amount of lubricating oil.
