Novel oil separator

Abstract

The invention discloses a novel oil separator which comprises an inertial oil separator body and a filtering oil separator body, wherein the inertial oil separator body comprises a cylinder I, supporting legs I, a baseplate, a gas inlet pipe I, a gas outlet pipe I and an oil return pipe I; the filtering oil separator body comprises a cylinder II, supporting legs II, a gas inlet pipe II, a gas outlet pipe II, a first oil return pipe II and a second oil return pipe II; the baseplate is of a triangular structure; an observation window I is arranged on the side wall of the cylinder I; an observation window II is arranged on the side wall of the cylinder II; a metal wire filtering screen is arranged at the inner top end of the cylinder II, takes the shape of a hemispherical curved surface, and is fixedly connected with the inner wall of the cylinder II; a gap is reserved between the metal wire filtering screen and the inner wall of the cylinder II; a gas outlet pipe shield is arranged at the lower end of the metal wire filtering screen; an end part of the gas outlet pipe II is positioned at the middle of the gas outlet pipe shield; and an oil collecting tank is arranged on the inner wall of the lower part inside the cylinder II. The novel oil separator disclosed by the invention is used for separating out lubricating oil in high-pressure gas and solving the problems that the heat transfer effect is impacted and the refrigerating efficiency is reduced because excessive lubricating oil enters a condenser and an evaporator.

Description

Technical field [0001] The invention belongs to the technical field of oil separation equipment. Specifically, the invention relates to a new type of oil separator. Background technique [0002] In the vapor compression refrigeration system, the compressed ammonia vapor (or freon vapor) is in a high-pressure and high-temperature superheated state. Due to the fast flow rate and high temperature of the gas discharged by the compressor, part of the lubricating oil on the cylinder wall will inevitably become oil vapor and oil droplet particles discharged together with the refrigerant vapor due to the effect of high temperature. Moreover, the higher the exhaust temperature and the faster the flow rate, the more lubricating oil will be discharged. Because the refrigerant and lubricating oil do not want to dissolve, when the lubricating oil enters the condenser and evaporator together with the refrigerant, it will be on the heat transfer wall. It condenses into a layer of oil film, whi...

Problems solved by technology

Moreover, the higher the exhaust temperature and the faster the flow rate, the more lubricating oil will be discharged. Since the refrigerant and the lubricating oil do not want to dissolve, when the lubricating oil enters the condenser and evaporator together with the refrigerant, it will be on the heat transfer wall. A layer of oil film is condensed, which increases the thermal resistance, reduces the heat transfer effect of the condenser and evaporator, reduces the cooling effect, and evaporates the lubricating oil of the compressor, which easily causes the compressor to malfunction and shortens the service life.
