Multilayered concentric type oil adsorption device and separator comprising same

Abstract

The invention relates to a multilayered concentric type oil adsorption device. A plurality of groups of gas distribution holes, which are distributed along the circumference, are formed in the outer circumference of a gas distribution guide pipe; axes of the gas distribution holes in the same group are located on a same horizontal plane; a plurality of oil adsorption barrels which are coaxial and have downward openings are coaxially distributed on an outer wall of the gas distribution guide pipe; each two adjacent oil adsorption barrels form one group; one group of the gas distribution holes are located in an annular cavity composed of the group of oil adsorption barrels. An ultrafine filter element does not need to be mounted in an oil separator adopting the oil adsorption device; the oil-gas separation efficiency is high, the service life is long and the repairing cost is low.

Description

technical field [0001] The invention relates to a multi-layer concentric oil attachment and a separator containing it, belonging to accessories of air compressor units or refrigeration compressor units. Background technique [0002] One of the key components of the air compressor unit, especially the screw air compressor unit, is the oil-gas separator. At present, the oil separation efficiency of the oil-gas separator used in the screw air compressor unit is relatively high, and the oil separation rate is above 99%. The reason why this kind of separator has a high oil separation efficiency is that there is a Only ultra-fine oil filter element, due to the high density of the filter element, impurities will block the inside of the oil filter element after a period of use, and the service life is 3000-5000 hours, so the oil filter element has become a frequently replaced accessory. The price of each filter element ranges from several hundred yuan to several thousand yuan, ther...

At present, the oil separation efficiency of the oil-gas separator used in the screw air compressor unit is relatively high, and the oil separation rate is above 99%. The reason why this kind of separator has a high oil separation efficiency is that there is a Only ultra-fine oil filter element, due to the high density of the filter element, impurities will block the inside of the oil filter element after a period of use, and the service life is 3000-5000 hours, so the oil filter element has become a frequently replaced accessory. The price of each filter element ranges from a few hundred yuan to several thousand yuan, which increases the maintenance cost

[0003] The internal structure of the oil-gas separator used in the refrigeration compressor unit is not equipped with ultra-fine filter elements, but adopts several methods such as middle partition type, spiral type, and centrifugal type, so the oil-gas separator used in the refrigeration unit does not need to replace accessories , high service life, but the oil-gas separator with intermediate partition structure, spiral or centrifugal structure has low oil separation efficiency, which can only achieve 80% to 90% oil separation effect
