Abstract

The utility model discloses a high-efficiency compressed air purifier. The existing purifier has the filtering method of one-time separation and one-time by filtration by a filter core, media required by the filter core are limited, and the frequent change and the frequent maintenance are needed. The high-efficiency compressed air purifier comprises an outer housing 1, an inlet 2, an outlet pipe 3, a nozzle box 4, a nozzle 5, an inner housing, an outer cavity 7, and an outer cavity 8. The utility model can carry out one-time whirlwind separation, one-time small hole condensation, and one-time whirlwind separation. The utility model is suitable for the high-efficiency purification operation of gas, particularly compressed air. Because utility model saves the filter core and saves the time for the change of the filter core, and the application range of the media is obviously enlarged, the utility model has a wide application range in the industry.

Description

High efficiency compressed air purifying device

The utility model relates to a kind of efficient air purifier.

Existing compressed air cleaner is the screw type air purifier, KJH series compressed air cleaner as the production of Guangzhou air compressor plant, after this clarifier separates by machinery, still need adopt filter core further to purify, reason is that the efficient of machinery separation is lower, owing to can not be higher than 200mg/m by the content of oil in the gas of filter core ³, and often renewal of filter core, bring inconvenience to production.

The compressed air cleaner that provides a kind of separative efficiency higher is provided the purpose of this utility model.

The purpose of this utility model is achieved in that

Its composition comprises: shell 1, the outlet 3 that is the inlet 2 of tangential nozzle, is connected with shell 1 with shell 1, inner chamber top at shell 1 is fixed with nozzle box 4, the outer wall of the nozzle 5 on the nozzle box 4 and the inwall oblique of nozzle box 4, inner casing 6 is connected with nozzle box 4, and be connected with shell 1, form exocoel 7 and inner chamber 8.

Advantage of the present utility model is:

1, the water in the compressed air has effectively been removed in separation through secondary centrifuging, oil and solia particle, make traditional one-time mechanical separate the technology that adds a filter element filtering and simplify greatly, working medium condition and production maintenance cycle also are greatly improved, and tangible technological progress is arranged.

When 2, the first time is centrifugal, in the rotary course of air-flow, airborne liquid etc. is sprayed onto on the outer casing inner wall, the medium such as the compressed air of above-mentioned impurity have been removed, during through nozzle, come down to and through an aperture condensation, further get rid of wherein liquid phase and solid phase, and then rush in the centrifugation that inner chamber carries out air-flow rotation for the second time.Structure of the present utility model makes the foregoing invention design be achieved.

3, removed the filter element filtering part, made production cost greatly reduce, and saved frequent filter core and changed the time, tangible economic benefit and social benefit have been arranged.

Accompanying drawing 1 is front view of the present utility model (complete section);

Accompanying drawing 2 is the A-A profile of Fig. 1.

Embodiment:

Its composition comprises, the shell 1 of cylindrical surface, two ends are sealed with end cap, sewage draining exit is housed on the bottom end cover, tangential inlet 2 is equipped with on shell 1 top, the center line of tangential inlet 2 in the porch a little more than with shell 1 intersection, be fixed with outlet 3 on shell 1 upper end cover, also be fixed with nozzle box 4 on the top of shell 1, nozzle 5 and outlet 3 are affixed but do not communicate, one group of nozzle 5 is arranged on the nozzle box 4, as 3～8 (deciding) according to the gentle speed of stream pressure, the inwall oblique of the outer wall of nozzle 5 and nozzle box, promptly nozzle does not intersect with nozzle box inwall center line at the cylinder centroidal line that Way out forms, formed the structure that tangential gas flow sprays into, and the inlet area of nozzle 5 is obviously greater than its discharge area, and inner casing 6 connects firmly with nozzle box 4, and connects firmly with shell 1, sewage draining exit is equipped with in the bottom, thereby forms exocoel 7 and inner chamber 8.From 2 air-flows that enter that enter the mouth, in by exocoel 7, form swirling eddy, then tangentially spray into inner chamber 8 and form the secondary swirling eddy by the nozzle on the nozzle box 45, then discharge from outlet 3.The angle of the outer wall of nozzle 5 and nozzle box 4 inwall obliques is: the angle of oblique place nozzle 5 outer walls acute angle in each bar normal at this place and the angle between this place's each point tangent line of nozzle box 4 inwalls is 5～75 °.The selection of angle promptly goes into implication speed by air-flow and the medium situation is determined, the cross section of nozzle 5 can be polygon, circle or the figure that closed curve constituted, and the bus in vertical section can be involute or circular arc.

Claims

1, a kind of efficient air purifier, its composition comprises: shell (1), the outlet (3) that is the inlet (2) of tangential nozzle, is connected with shell (1) with shell (1), it is characterized in that: the inner chamber top of described shell (1) is fixed with nozzle box (4), the outer wall of the nozzle (5) on the nozzle box (4) and the inwall oblique of nozzle box (4), inner casing (6) is connected with nozzle box (4), and be connected with shell (1), form exocoel (7) and inner chamber (8).

2, efficient air purifier according to claim 1 is characterized in that: the angle of the outer wall of described nozzle (5) and nozzle box (4) inwall oblique is: the angle of oblique place nozzle (5) outer wall acute angle in each bar normal at this place and the angle between this place's each point tangent line of nozzle box (4) inwall is 5～75 °.

3, efficient air purifier according to claim 1 and 2 is characterized in that: the bus of described nozzle (5) is involute or circular arc, and the inlet of nozzle (5) is greater than outlet.
