The utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure compact, and effectively can carry out being separated of machine oil and gas, good separating effect, efficiency are high, and the machine oil after separation can obtain the segregating unit effectively reclaimed.
To achieve these goals, the utility model is by the following technical solutions:
A kind of gas and oil separating plant, comprise once first branch, secondary fine branch, described once first branch comprises main cylinder, described main cylinder comprises air intake surrounding portion, cyclone separating tube, described air intake surrounding portion is in above cyclone separating tube, described air intake surrounding portion is provided with around airduct, first air intake pipe, the air intake direction of described first air intake pipe is towards around airduct sidewall, described around airduct lower ending opening towards cyclone separating tube, upper end is communicated with whirlwind exhaust outlet, return check valve is provided with bottom described cyclone separating tube, described unidirectional scavenger valve connects just return tube, described first return tube is communicated with oil sump, described secondary fine branch comprises smart branch mailbox, some overhead gages are provided with in described smart branch mailbox, some lower pedals, described overhead gage, lower pedal, an essence point chamber interior wall forms air vent jointly, the suction port of described air vent is communicated with whirlwind exhaust outlet, the air outlet of described air vent is communicated with terminal relief opening, described lower pedal bottom was provided with oily micropore, described smart branch mailbox is provided with oil collection pipe.After the mixed gas containing mist of oil enters air intake surrounding portion from first air intake pipe, air-flow by guide vane guide functions and around flowing fast around airduct, produce strong rotation, air-flow starts screw current downflow along cyclone separating tube sidewall, the oil droplet that density is large is thrown toward sidewall under centrifugal action, and under gravity, flow downward to return check valve along air intake surrounding portion, cyclone separating tube madial wall, and flow back in oil sump through first return tube.The air-flow rotated shrinks to center flow in cylindrical shell, collects in after bottom cyclone separating tube, upwards forming secondary vortex flow through flowing out to top whirlwind exhaust outlet around airduct, completing initial gross separation, being namely separated in a large number, efficiently.Then the mixed airflow still containing a small amount of machine oil enters secondary fine branch, high velocity air clashes into overhead gage, lower pedal, and while cooling, machine oil aerosol liquefies, and baffle plate forms oil droplet, glides along baffle plate, finally flow out from oil collection pipe and reclaim, fully ensure that being separated of machine oil and gas, decrease the waste of machine oil, prevent machine oil from discharging or entering firing chamber.
As preferably, be provided with asphalt felt bottom described cyclone separating tube, described asphalt felt to cover bottom cyclone separating tube and sidewall bottom cyclone separating tube, is provided with filter mesh layer between described asphalt felt and return check valve.Mixed gas arrives after bottom cyclone separating tube, start to collect, rise, easily take away the machine oil of bottom, the existence of asphalt felt, effectively can absorb the machine oil that clever cyclone separating tube sidewall flows down, air-flow can not be taken away, and absorb a certain amount of after under ooze, from return check valve flow out, reclaim.Further, the effect of impurity screening can be played, prevent impurities accumulation and cause blocking return check valve.
As preferably, recessed formation oil-collecting depression in the middle of bottom described smart branch mailbox, described oil collection pipe one end is communicated with oil-collecting concave bottom, the other end is communicated with oil sump.Facilitate the machine oil centralized recovery stayed in smart branch mailbox, and flow out recovery by oil collection pipe.
As preferably, described cyclone separating tube madial wall is provided with the wind deflector of some inside inclined downward.Improve flow rotation, increase cyclone effect, improve machine oil and throw away ability.
The beneficial effects of the utility model are: have two-stage piece-rate system, crude separation, essence can be separated, ensure to be separated thoroughly; Cyclonic separation rapidly and efficiently, and consolidates separating effect by asphalt felt, can prevent machine oil from being taken back mixed gas by secondary; There is return check valve structure, avoid machine oil to reflux, improve separation effect.
