Abstract
The invention discloses a cyclone oil-gas separator for a multi-online system. The cyclone oil-gas separator comprises a main cylindrical barrel, a tangential inlet pipe is arranged on the upper side wall of the main barrel, a vertical exhaust pipe is arranged at the top center of the main barrel, the bottom of the exhaust pipe extends into the main barrel, a vertical oil discharging pipe is arranged at the bottom center of the main barrel, the inlet pipe is connected with an exhaust pipe of an air conditioning multi-online system compressor, the vertical exhaust pipe is connected with an inlet of a condenser, the oil discharging pipe is connected with an inlet pipe of a gas-liquid separator, the diameters of the tangential inlet pipe and the vertical exhaust pipe are di and do respectively, the pipe pitch between the tangential inlet pipe and the vertical exhaust pipe is d, d<(di/2+do/2), part of fluid led into by the tangential inlet pipe collides with the vertical exhaust pipe, the entered fluid regularly flows around an annular space formed by the vertical exhaust pipe and the main barrel when the fluid flows stably, and oil after being separated is discharged from the cyclone oil-gas separator through the oil discharging pipe. The probability that small oil drops adhere to wall faces and oil drops aggregate is increased by means of inlet gas collision, and accordingly separating efficiency is improved.
Description
Technical field
The invention belongs to refrigeration and cryogenic engineering technical field, be specifically related to a kind of many on-line systems and use cyclone type oil-gas separator.
Background technology
Many onlinely have irreplaceable status in the central air-conditioning field; The demand how online to long pipe arrangement appearred in the development in market; Owing to contain more lubricating oil drop in the compressor air-discharging; The separative efficiency of gs-oil separator directly affects safe operation and the service life of compressor etc., and present engineering practice shows that the oil return problem in many on-line systems is the big difficult point in its design.The research of both at home and abroad air-conditioning being got in touch cold-producing medium-oil in the system more focuses mostly at distribution and the delay of lubricating oil in system, the aspects such as change of gs-oil separator macrostructure form, relates to seldom and air-conditioning is got in touch the numerical simulation study of uniting with the gs-oil separator interior flow field more.
The structural design of relevant cyclone type oil-gas separator is a sample with the air inlet non-collision structure all; This makes in the annular release space that main cylinder and blast pipe form has a more small particle diameter oil droplet near the position of exhaust tube wall is free; Its inertia is less; Suffered centrifugal force is also less, follow easily refrigerant gas together be deflated the pipe siphon away, thereby reduce its separative efficiency.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of many on-line systems to use cyclone type oil-gas separator, improved separative efficiency.
In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of many on-line systems are used cyclone type oil-gas separator, comprise cylindrical main cylinder 1, and main cylinder 1 upper portion side wall is provided with a tangential inlet tube 2; Main cylinder 1 center of top is provided with a vertical blast pipe 3, and blast pipe 3 bottoms are stretched in the main cylinder 1, and main cylinder 1 bottom central is provided with a vertical oil exit pipe 4; Inlet tube 2 links to each other with the blast pipe that air-conditioning is got in touch the system compressor more; Blast pipe 3 links to each other with condenser inlet, and oil exit pipe 4 links to each other with the gas-liquid separator inlet tube, and the diameter of inlet tube 2 is d
i, the diameter of blast pipe 3 is d
o, 3 liang of pipes of inlet tube 2 and blast pipe tube pitch is d, d<(d
i/ 2+d
o/ 2).
Beneficial effect of the present invention is:
Be with conventional cyclone type oil-gas separator difference; The part wall of some and blast pipe bumps against in the two-phase fluid that inlet tube 2 of the present invention is imported; But continuous operation along with many on-line systems; Reach stable after, inlet fluid and blast pipe 3 tube walls no longer include collision phenomenon, flow-disturbing moves but in main cylinder 1 and blast pipe 3 formed annular release spaces, carry out clocklike.Because air inlet 2 is provided with the difference of position and caliber, cause comparing with the conventional gas and oil separator, air inlet fluid of the present invention more trends towards being rotated flow-disturbing around blast pipe 3, and the small particle diameter oil droplet is deflated the pipe outer tube wall more easily and catches.Simultaneously, ambient fluid still can get rid of oil droplet to the internal face of main cylinder 1 under bigger tangential velocity.
Collide the probability that increases little oil droplet adhesion wall and oil droplet polymerization through air inlet, reduce flow area, increase tangential velocity, improve the suffered centrifugal force of oil droplet, thereby improved separative efficiency.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done detailed description.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of many on-line systems are used cyclone type oil-gas separator, comprise cylindrical main cylinder 1; Main cylinder 1 upper portion side wall is provided with a tangential inlet tube 2, and main cylinder 1 center of top is provided with a vertical blast pipe 3, and blast pipe 3 bottoms are stretched in the main cylinder 1; Main cylinder 1 bottom central is provided with a vertical oil exit pipe 4; Inlet tube 2 links to each other with the blast pipe that air-conditioning is got in touch the system compressor more, and blast pipe 3 links to each other with condenser inlet, and oil exit pipe 4 links to each other with the gas-liquid separator inlet tube; With reference to Fig. 4, the diameter of inlet tube 2 is d
i, the diameter of blast pipe 3 is d
o, 3 liang of pipes of inlet tube 2 and blast pipe tube pitch is d, d<(d
i/ 2+d
o/ 2).
Operation principle of the present invention is:
The segment fluid flow that imports through inlet tube 2 can collide blast pipe 3; Behind mobile the stablizing; Getting into fluid will clocklike stream in the annular space that blast pipe 3 and main cylinder 1 form; The form of streaming changes with the difference of air inlet collision degree; Air inlet collision degree is big more, and the fluid that inlet tube 2 imports trends towards blast pipe 3 outer walls are carried out flow-disturbing in annular space; Air inlet collision degree is more little; The fluid that inlet tube 2 imports trends towards main cylinder 1 inwall is carried out flow-disturbing in annular space; Reasonably degree is collided in the adjustment air inlet; Can obtain the width of flow path an of the best; Increase the small particle diameter oil droplet that is free in annular space originally and collide the probability that wall is captured, the oil after the separation is discharged cyclone type oil-gas separators through oil exit pipe 4.
