Description

The high-efficiency oil-gas separating device of safety and environmental protection
Technical field
The present invention relates to a kind of deaerator, especially relate to the high-efficiency oil-gas separating device of the safety and environmental protection that a kind of oil gas that crankcase is discharged separates.
Background technique
As everyone knows, contain organic oil in the mixed gas of the crankcase scavenged of internal-combustion engine, in reclaiming combustion process, can be adsorbed on each parts of internal-combustion engine, form carbon deposit, reduce the service behaviour of internal-combustion engine, quicken the waste of internal-combustion engine abrasion and machine oil, reduce engine operation efficient, shorten the life-span, discharge more harmful gas befouling environment simultaneously.So reclaim the machine oil in the mixed gas, so there is the people to design a kind of gas and oil separating plant, for example the patent No. is a kind of gas and oil separating plant of 95218800.7, it is provided with a helical separator tube at sealing shell, the mixed gas that crankcase is discharged is mapped on the separator tube, and machine oil just apposition temporarily flows out on separator tube and along separator tube, though this invention is simple in structure, but can only drip shape machine oil more greatly by separating particles, vaporific machine oil is not played good separating effect; Also the someone designs a kind of gas and oil separating plant (patent No.: 97202028.4) last lower box is arranged of diesel engine, mandrel and filter disc, spacer is arranged between filter disc and adopted filter screen device, this model utility had bigger improvement to former technology, mainly be that filtration by filter screen comes separation oil and gas, but exist filter disc or filter screen to stop up easily equally, under the effect of internal-combustion engine continuous negative pressure, can not regulate pressure with the balance crankcase, the adsorption force of vaporific machine oil on filter disc or filter screen is little, just can not separate vaporific machine oil better.Someone also design other as the labyrinth, gas and oil separating plants such as negative pressure control, but all exist can not regulate with the balance crankcase pressure with can not separate technical problems such as vaporific machine oil fully efficiently, and be very easy to stop up filter screen, working life is shorter, more can not adapt to the technical requirements of internal-combustion engine each period, each operating mode.In addition, existing most of gas and oil separating plant does not have automatic warning function, and when gas and oil separating plant caused device total failure because of filter screen stops up, the user can not in time find and it be cleaned, be very easy to cause the damage of internal-combustion engine thus, cause heavy losses to the user.
Summary of the invention
The present invention mainly is at the technical problem that existing in prior technology can not balance crankshaft case pressure, separation effect is low, have potential safety hazard, working life is short etc., and the high-efficiency oil-gas separating device of the safety and environmental protection of a kind of case of balance crankshaft effectively pressure, separation effect height, safe and reliable, long service life is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of high-efficiency oil-gas separating device of safety and environmental protection, comprise casing, loam cake, suction port, air outlet and the return opening that is arranged on bottom half, filter screen I is arranged between suction port and the air outlet, cavity is separated into preceding cavity of filter and filter rear chamber, be provided with oil deflector in the cavity before the filter, it is characterized in that described filter screen I upper end is provided with ring-type filter screen II, be provided with dividing plate between filter screen I and the filter screen II, described dividing plate is provided with some groups of through holes.The filter screen II of ring-type is arranged between loam cake and the dividing plate, increased filter screen and oil gas area of contact, improved separation effect; On the dividing plate that is provided with between filter screen I and the filter screen II, offer the through hole of some groups of rules, make-up air enters filter screen I and filter rear chamber respectively by the through hole on the dividing plate, filter screen II not only can filter from airborne sand and dust, can also separate the oil gas that enters from by-pass hole, with work safety and the service behaviour of guaranteeing turbosupercharger; On the other hand, can also stablize the effect of negative pressure on filter screen I, keep the adhesion of machine oil on filter screen I; When air entered filter screen I under suction function, because the flow direction of air is consistent with the gravitational direction of machine oil, therefore, make-up air can be accelerated the speed that machine oil flows downward, and prevents that filter screen is saturated by machine oil, improves the passing ability of gas on filter screen I; On the other hand, the air interleaving techniques combines with the filter screen technology, can tackle the more machine oil particle of small particle diameter, under equal densities filter screen condition, can improve the separation effect of oil gas greatly.
