But above all types of graders often separating effect do not reach requirement yet, and separating effect is better, and the machining accuracy of requirement and the complexity of system are also higher.Therefore need a kind of not only economy but also efficiently technology solve this problem.
Summary of the invention
The present invention is directed to the problems referred to above, proposed a kind of horizontal rectification type oil eliminator.Solved prior art separating effect and do not met the requirements of problem, and prior art is for reaching good separating effect, machining accuracy and the complexity of separator are higher, cause the problem that cost is higher.
The technical scheme that the present invention takes is as follows:
A horizontal rectification type oil eliminator, comprises fuel reserve tank, rectifying separator box and the vent line and the return line that are communicated with between;
Wherein, described fuel reserve tank is provided with air inlet and oil return opening, and fuel reserve tank inside is provided with skimming baffle;
Described rectifying separator box is provided with gas outlet, and rectifying separator box inner upper end is provided with cooling coil; The top contact heat-exchanging of rectifying separator box bottom and fuel reserve tank.
Described air inlet is arranged on the sidewall of fuel reserve tank.
Operation principle of the present invention is, after processing through compressor compresses process, with oily mist, by air inlet, enter in fuel reserve tank, and enter after fuel reserve tank, because ventilation sectional area increases, thereby the speed of gas declines, thereby the oil droplet that diameter is larger starts to fall to completing first separation under the effect of gravity, then remaining mist is through the effect of skimming baffle, thereby on skimming baffle, bump and change flow velocity direction the oil droplet of small diameter is carried out to secondary separation, the separated fluid getting off is got back to compressor through oil return opening under the pressure reduction of upper and lower oil level and Action of Gravity Field, avoided compressor to run the too much phenomenon of oil.Mist through secondary separation then enters rectifying separator box through vent line, during due to first separation and secondary separation can there is exchange heat in the lower end of refrigerant gas and skimming baffle and rectifying separator box, make the lower end of rectifying separator box produce a thermal source, simultaneously cooling coil forms a low-temperature receiver in rectifying separator box inner upper end, thus the gaseous mixture after secondary separation know from experience there is separating for several times here rectification effect the most at last the oil in gas thoroughly remove.Gas after the separation of the third level is discharged oil eliminator through gas outlet, can under the effect of gravity, through return line, drain in fuel reserve tank, and finally by oil return opening, flow in compressor when the fluid simultaneously separating runs up to a certain degree.
As preferably, filler is also equipped with in described rectifying separator box inside.
By filler is set, for heat and mass provides place.Forming thermal source and low-temperature receiver is the necessary condition of rectifying separation process, the process of rectifying is the process that a mass transfer is accompanied by heat transfer, gas-liquid two-phase fluid constantly rises and falls under the effect of low-temperature receiver and thermal source and gravity, and in filler, carry out heat and mass transport, could form like this effect of rectifying.Mainly that the part that gaseous fluid volatility is less (oil) comprises the cold liquid state whereabouts that becomes of the oil droplet that diameter is very little (being similar to gaseous state) rising chance simultaneously, run into the mixture steam that is heated and rises at rectifying cylinder body bottom, be equivalent to carry out mass exchange in this mass transfer media of filler, make the oil content of liquid oil droplet more and more higher, separated through repeatedly such rectifying, thus reach efficient separating effect.
Described cooling coil has inlet and the liquid outlet that passes respectively rectifying separator box.
As preferably, described fuel reserve tank and rectifying separator box are horizontal tubular structure, and the top of described fuel reserve tank is with bogging down area, and described rectifying separator box bottom is positioned at this place, bogging down area.
The efficiency of tubular structure is higher, and by arrange bogging down area make fuel reserve tank and the direct contact area of rectifying separator box larger, heat exchange efficiency is high.
In order to improve oil return efficiency, as preferably, described return line one end is arranged on the lower end of rectifying separator box, and the other end is arranged on the lower end of fuel reserve tank.
The oil of separating can be deposited on bottom, and the such setting of return line can effectively drain into oil separated in rectifying separator box in fuel reserve tank, converges with oil separated in fuel reserve tank, together by oil return opening, flows out.
In order there to be better separating effect, as preferably, described vent line one end is arranged on the upper end of fuel reserve tank, and the other end is arranged on the lower end of rectifying separator box.
As preferably, described skimming baffle is spaced apart a plurality of, and the top of each skimming baffle is equipped with by hole, and lower end was provided with hydraulic fluid port.
Setting facilitates passing through of mist by hole, by hydraulic fluid port is set, can make the oil stream that each skimming baffle is separated conflux to oil return opening by crossing hydraulic fluid port.
In order to make secondary separation better effects if, mist circulation area is larger, as preferably, is arranged on a side on skimming baffle top by hole, and the hole heteropleural that passes through on adjacent two skimming baffles is arranged.
As preferably, described oil return opening is arranged on the bottom of fuel reserve tank.
More preferred, the bottom of described fuel reserve tank is in tilted layout, and described oil return opening is located at position lowest part.
The invention has the beneficial effects as follows: air inlet is arranged on the sidewall of fuel reserve tank, the effect gaseous mixture physical efficiency by gravity completes first separation, and larger oil droplet is separated; By skimming baffle is set in fuel reserve tank, less oil droplet is carried out to secondary separation; By rectifying separator box, utilize rectifying separated away from less oil droplet and oil gas body being carried out to three times.
