Description

technical field [0001] The present invention relates to a gas-liquid separator, in particular to a separator combining centrifugal separation, baffles and filters. Background technique [0002] The premise of the gas-liquid separator to achieve gas-liquid separation is that the density between the gas and the liquid is different, and it is realized by gravity separation, centrifugal separation, inertial separation, filtration separation and other methods. Gas-liquid separators are widely used in many fields, such as oil-water separation of compressed air, oil-gas separation in the refrigeration field, gas-liquid separation in oil fields, etc., all require various types of separators. [0003] At present, there are many structural forms of gas-liquid separators. A common horizontal structure gas-liquid separator, the main structural form is that the shell is equipped with baffles, pre-separation components and filters, etc. The disadvantages of this separator are low separat...

AI Technical Summary

Problems solved by technology

A common horizontal structure gas-liquid separator, the main structure is that the shell is equipped with baffles, pre-separation components and filters, etc. The disadvantage of this separator is that the separation capacity is low, the equipment is heavy, and it occupies a large area

Another common structural form is the centrifugal separator, which utilizes the difference in gas-liquid density, and through the high-speed rotation of the gas-liquid mixture, the liquid droplets are gathered on the wall of the separator. The disadvantage of this equipment is that the separated gas contains liquid droplets. Poor variable flow

Another common structural form is porous media filtration. The principle is that when the air flow passes through the porous media, the liquid particles coalesce and grow on the inner surface of the filter element due to the coalescence function of the filter medium; when the droplets reach a certain size, due to gravity and air flow The impact force flows out of the material chamber, the disadvantage is that the pressure drop is high, and it is not suitable for occasions with high liquid content
