Abstract
The utility model relates to an air inlet preseparating unit of compound air cleaner, which is composed of an air intake segment, a predissociation chamber, a ring inner cone, and an ash bucket. The air inlet preseparating unit of compound air cleaner is arranged on the out side of the air inlet of a coarse filter. Dusty air is sprayed into the preseparating chamber through a ring nozzle with acceleration, and is preseparated by gas-solid inertia differences. Thus only small quantity of fine dust can enter a fine filter, and the service life of the paper filter element of the fine filter can be extended. The parasitic pressure drop of the utility model is only 20-130 Pa, and can not influence the power and performance of a combustion engine. The preseparating unit of the utility model is applied to a 190 series diesel engine for air inlet preseparating of a compound air cleaner, and is applied to other equipment such as a combustion engine, an air compressor, and an air exhauster, etc. which need air inlet preseparating.
Description
The utility model relates to internal-combustion engine combined type air-strainer field.
At present both at home and abroad in the desert and the internal-combustion engine of high dust-laden district work use by strainer 7(minor diameter multicyclone group 3) and secondary filter 12(paper filter element) the combined type air-strainer formed.Through the minor diameter multicyclone group 3 in the strainer 7, grit is separated under centrifugal action dust laden air, and is collected in the dust hopper 2 earlier, and the air of purification enters secondary filter 12 again, enters internal-combustion engine again after paper filter element filtration wherein.The strainer suction port 8 of this air-strainer opens wide substantially, and the air of carrying dust and sand-lime secretly directly enters strainer 7 through any hardly with stopping, thus internal-combustion engine in the desert and high dust-laden area be difficult to continuous proper functioning.
The purpose of this utility model is: a kind of suction port pre-separate device of combined type air-strainer is provided, the dust that enters air-strainer is controlled in certain scope, to guarantee that internal-combustion engine is in the desert and high dust-laden area proper functioning continuously.
The purpose of this utility model realizes by following solution: set up a pre-separate device outside former strainer 7, promptly in coarse filtration suction port 8 outsides air inlet section 10, pre-separation chamber 1, annular internal cones 11, ash bucket 5 and dust exhaust port 6 are installed.Air inlet section 10, annular internal cones 11 and pre-separation chamber 1 are installed in suction port 8 outsides of strainer 7 with one heart, and ash bucket 5 is positioned at the below of pre-separation chamber 1, and air inlet section 10 and annular internal cones 11 form an annular jet 9 that tilts laterally in pre-separation chamber 1.Air is sucked by air inlet section 10, the annular jet 9 that forms a flare oblique angle 13 via air inlet section 10 and the annular internal cones 11 with semi-cone angle 14 in pre-separation chamber 1 quickens to spray into pre-separation chamber 1, utilize the inertia of gas-solid two-phase movement poor, bigger grit is separated from air-flow, and falls within dust discharge in the ash bucket 5.Air through pre-separation enters strainer 7 continuation purifications from coarse filtration suction port 8 again, thereby making dust contained in the air was that major part is separated before entering strainer 7, have only a small amount of fine powder can enter air-strainer, can prolong the working life of paper filter element in the secondary filter 12 greatly, can also improve total arresting efficiency, even make its also proper functioning continuously under desert strong wind sand and high dust-laden condition.
Accompanying drawing 1 is the structural representation of suction port pre-separate device.
Number in the figure is: pre-separation chamber 1, dust hopper 2, minor diameter multicyclone group 3, strainer dust exhaust port 4, ash bucket 5, dust exhaust port 6, strainer 7, coarse filtration suction port 8, annular jet 9, air inlet section 10, annular internal cones 11, secondary filter 12, flare oblique angle 13, semi-cone angle 14.
The utility model is compared with original technology, structurally do not change body construction and the size of former air filter, just increase an air inlet pre-separate device, simple in structure, there is not moving component, do not need additionaling power, do not need specialized operations control yet, can carry out pre-separation to dust laden air as long as the former air filter of internal combustion engine runs well, greatly improve the ability of processing dust laden air, to adapt to the mal-condition in desert and high dust-laden area.
Embodiment of the present utility model is the suction port pre-separate device that is applied to 190 serial diesel engine air-strainer.Air inlet section 10 diameters are 600-650mm, and the semi-cone angle 14 of annular internal cones 11 is 25 °-35 °, and the facies basialis pyramidis diameter is 500-570mm, and annular jet 9 radial width are 30-35mm, and flare oblique angle 13 is 20 °-40 °, and pre-separation chamber 1 external diameter is 745mm.
In 190 serial diesel engine normal range of operation, be that the pre-separation efficient of 80 purpose sand grains is 82-97% to granularity, promptly have only the fine dust of 3-18% just can enter strainer, can prolong the working life of micronic paper filter core greatly.And the parasitic pressure drop of this pre-separate device only is the 20-130 handkerchief, to the not influence of overall presure drop of air-strainer, therefore also can not influence the power and the performance of diesel engine.The suction port pre-separate device of combined type air-strainer also can be used for equipment such as other internal-combustion engine that needs the suction port pre-separation, air compressor and induced draft fan.
