Description

  The present invention relates to an engine generator such as a cogeneration apparatus, for example.

  2. Description of the Related Art Conventionally, an engine generator that houses an engine and a generator in a package, for example, has a configuration in which an air cleaner and an intake duct are connected (see, for example, Patent Document 1). Since such an engine generator may be installed outdoors, when a drop of rainwater or the like enters the package when sucking outside air from the intake duct, the sponge-like filter paper provided in the air cleaner gets wet. End up. As a result, the filter paper is clogged, and the air cleaner cannot take in outside air.

  Therefore, the engine generator described in Patent Document 1 includes a lower side of the outside air inlet 102 formed in the upper surface opening recess 101 located at the center of the soundproof housing 100 and the soundproof housing 100 as shown in FIG. A step portion 104 is formed between the bottom surface of the intake duct 103 provided in the upper portion. The step portion 104 is configured to prevent rainwater from entering the intake duct 103.

Utility Model Registration No. 2503851

  In the configuration described in Patent Document 1, the step portion 104 is formed between the lower side of the outside air introduction port 102 and the bottom surface of the intake duct 103. Although it is possible to remove the rainwater itself that directly enters the intake duct 103, it is not possible to remove even the water droplets sucked together with the outside air.

  And if the water droplet which passed the air cleaner is mixed with the air for engine combustion, there will be a problem which causes acid corrosion and exhaust drain water.

  Then, the subject of this invention is providing the structure which can remove a water droplet from the external air just before suck | inhaling from an air cleaner.

  The present invention has been made to solve the above-described problem, and is an engine generator that has an air cleaner in an intake path and houses an engine and a generator driven by the engine in a package, and the air cleaner is installed in the package. The air intake duct is disposed so as to face the opening in the package, and a partition member is provided between the opening in the package and the air cleaner.

  According to the present invention, since the outside air sucked through the intake duct collides with the partition member before the air cleaner flows in, the outside air can be drained by the partition member. As a result, outside air from which water droplets have been removed can be supplied to the air cleaner.

  In the engine generator, an opening in the package of the intake duct is provided substantially horizontally and above the air cleaner.

  In the present invention, since the opening in the package of the air intake duct is provided substantially horizontally and above the air cleaner, water droplets such as rainwater are applied to the partition member provided between the opening in the package and the air cleaner. This makes it easier to drop and further improves the draining effect of outside air. In addition, providing the opening in the package substantially horizontally means that the water drops can pass through the opening in the package without hindrance.

  In the engine generator, the partition member is inclined and arranged to face the opening in the package.

  According to the present invention, water droplets removed from the outside air by the partition member can be collected on one side, and the drainage is improved.

  In the present invention, since the outside air sucked through the intake duct collides with the partition member before the air cleaner flows in, even if the outside air is mixed with water droplets such as rainwater, powdered snow, etc., the outside member is drained by the partition member. As a result, the outside air from which water droplets have been removed can be supplied to the air cleaner.

FIG. 1 is a front perspective view showing the outline of the entire cogeneration apparatus of the present embodiment, and FIG. 2 is a rear perspective view showing the outline of the entire cogeneration apparatus.

  As shown in FIGS. 1 and 2, the package 1 of the cogeneration apparatus of the present embodiment includes a package main body 10 that is grounded, and a central duct 20 that is provided on the upper surface of the package main body 10 and in the center in the longitudinal direction. The intake duct 30 connected to one end side of the central duct 20 and the exhaust duct 50 connected to the other end side of the central duct 20 are provided.

  In the package body 10, a generator unit 12, a high voltage board 13, a cockpit 18, a power distribution board 19, a low voltage board 11, and the like are arranged. The generator unit 12 includes an engine 15 and a generator 16. The cockpit 18 is provided with an electronic control device that controls the gas engine 15 and the generator 16 and generator instruments (such as a voltmeter, an ammeter, and a voltage regulator), and is disposed below the intake duct 30. Yes. In the vicinity of the gas engine 15, a lubricating oil tank 17 in which lubricating oil supplied to the gas engine 15 is stored is provided.

  The switchboard 19 takes in external power and supplies predetermined power to the ventilation fan 31 and an engine coolant pump (not shown) via the low-pressure board 11, and is arranged on the side of the generator 16. .

  A deodorizing catalyst 21 as an exhaust gas related device is incorporated in the central duct 20. The deodorizing catalyst 21 is connected to the engine exhaust port through an exhaust pipe 22 penetrating the partition wall.

  The intake duct 30 takes outside air (air) into the package body 10 and is provided on the upper end of one end side in the longitudinal direction of the package body 10 (right side in the left-right direction in FIG. 1). In addition, a plurality of ventilation fans 31 (two are exemplified in the present embodiment) are incorporated in the intake duct 30.

  Then, as shown in FIG. 6, the ventilation fan 31 is fixed to the intake duct bottom wall 30a, and the outside air sucked by the ventilation fan 31 through the in-package opening 30b formed in the intake duct bottom wall 30a, It can be introduced into the package body 10. The in-package opening 30b is provided substantially horizontally.

  An air cleaner 25 provided with a filter paper that sucks outside air introduced into the package body 10 and removes dust contained in the outside air is disposed facing the inside opening 30 b of the intake duct 30. That is, a plurality (three in this embodiment) of air cleaners 25 are mounted on the gantry 26 so as to have a predetermined distance from the intake duct bottom wall 30a below the substantially horizontal package opening 30b. .

  A partition member 6 is provided between the package opening 30 b and the air cleaner 25. As shown in FIGS. 3 to 6, the partition member 6 receives water droplets from the package opening 30 b of the intake duct 30 and removes the water droplets from the outside air so that the water droplets are not sucked into the air cleaner 25. A bottom plate 61 made of a plate-like body having a rectangular shape in plan view, an outer frame member 62 provided on the outer periphery of the bottom plate 61 and higher than the bottom plate 61, and provided on an upper surface of the bottom plate 61 and the bottom plate 61. And a partition member 63 that divides the portion into a plurality of portions.

  The partition member 6 is appropriately set to a size having an area that covers all the air cleaners 25 from above. Further, the partition member 63 is not necessarily provided.

  The partition member 6 is fixed to the constituent members such as the gantry 26 via a stay 64 so as to be gradually lowered toward the arrow X direction (one end side in the longitudinal direction of the package body 10) shown in FIG. ing. In addition, a communication port (not shown) is appropriately formed in each partition member 63 so that water droplets flow through the communication port of each partition member 63 to the lower side.

  A discharge pipe (not shown) is connected to the lower side of the bottom plate 61, and water drops received by the bottom plate 61 can be discharged appropriately through this discharge pipe. It is also possible to detachably attach the water droplet storage part to the bottom plate 61, remove the water droplet storage part from the bottom plate, and appropriately discard the water droplets stored in the storage part.

  An intake hood 43 that communicates with the intake duct 30 protrudes from one end of the intake duct 30. The lower surface of the intake hood 43 is opened. Here, an intake passage is formed by the intake hood 43 and the intake duct 30.

  The exhaust duct 50 is provided with an exhaust hood 51 having an air outlet (not shown) formed on the lower surface thereof so that air in the package body 10 is discharged through the air outlet.

  Next, the case where the cogeneration apparatus having the above configuration is operated will be described.

  The cogeneration apparatus generates electric power by driving the gas engine 15 and rotationally driving the generator 16, and the generated electric power is supplied to an external power load. Further, the power is supplied to the switchboard 19 via an external power input line (not shown). When the engine is driven, each ventilation fan 31 operates.

  The ventilation fan 31 takes outside air into the intake hood 43 by the suction force. The taken outside air flows through the intake duct 30 and enters the package body 10. The outside air that has flowed into the package body 10 flows downward, and first collides with the bottom plate 61 of the partition member 6 from above.

  The outside air that has collided with the bottom plate 61 changes the flow to the outside of the bottom plate 61 and then flows further downward beyond the outer frame member 62.

  Thus, the outside air that has passed through the partition member 6 passes through the air cleaner 25 and is supplied to the gas engine 15, and after cooling components such as the gas engine 15, the outside air passes through the exhaust duct 50 and the exhaust hood 51. And discharged outside the package body 10.

  Depending on weather conditions such as rainy weather, water drops such as mist rainwater may be mixed in the outside air, and the water drops may enter the package body 10 together with the outside air.

  Since the water droplets that have entered the package body 10 collide with the outside air against the bottom plate 61 of the partition member 6 from above, the bottom plate 61 receives the water droplets. As a result, the downward flow of water droplets is blocked by the partition member 6, and the water droplets flow to the lower side on the inclined bottom plate 61 and are appropriately drained.

  When a discharge pipe is connected to the bottom plate 61, water droplets received by the bottom plate 61 can be appropriately discharged through the discharge pipe. Further, when the water droplet storage part is detachably provided on the bottom plate 61, the water droplets are temporarily stored in the water droplet storage part, the water droplet storage part is removed from the bottom plate 61, and the water drops stored in the water droplet storage part are discarded. .

  As described above, even when water droplets are inadvertently sucked into the package body 10 together with the outside air, the water droplets are removed from the outside air by the partition member 6, and the water droplets enter each air cleaner 25. Can be prevented. As a result, since only the outside air passes through the air cleaner 25, the air cleaner 25 is not moistened with water droplets, the occurrence of clogging due to the wetness of the air cleaner 25 can be prevented, and the performance of the air cleaner 25 can be maintained.

  Further, since the engine 15 does not suck water droplets that have passed through the air cleaner 25, the problems of acid corrosion and exhaust drain water caused by the water droplets that have passed through the air cleaner 25 can be solved, and engine trouble can be prevented from occurring.

  The present invention is not limited to the embodiment described above. For example, in the said embodiment, although the partition member 6 illustrated the thing of a planar shape and inclined the partition member 6 and improved the discharge | emission property of water droplets, the partition member 6 becomes upward convex shape. It may be curved.

  Moreover, although the case where the ventilation fan 31 was installed horizontally was illustrated, as shown in FIG. 7, the case where the ventilation fan 31 is installed vertically may be sufficient. In addition, when the ventilation fan 31 is placed horizontally, the case where the outside air passing through the ventilation fan 31 flows downward is referred to as landscape installation. Further, the vertical installation of the ventilation fan 31 refers to a case where the outside air passing through the ventilation fan 31 flows in the horizontal direction.

  Although this embodiment illustrated about a cogeneration apparatus, this invention can also be employ | adopted for GHP (gas heat pump).
