Description

Generator {GENERATOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generating device, and more particularly to a power generating device capable of supplying emergency or constant power through an internal combustion engine of a generator.

Generators generally refer to devices that convert mechanical energy into electrical energy. The generator is operated so as to supply power at all times or to supply power temporarily only when the main power supply, which is a commercial power supply, is stopped.

Emergency generators used in the emergency are installed inside the building, and there is a possibility that there is a plan interruption due to the failure or repair of the external electric power facility, external factors due to the shortage of the electric power reserve, failure or maintenance or ground fault of the internal electric power facility, It must be installed in case of interruption due to fire or interruption due to internal factors caused by arbitrary supply of commercial power.

Such emergency generator is mainstream of generator driven by diesel engine. Demand is continuously increasing because diesel engine generator can operate with high efficiency and high output. In addition, since the cost of diesel is lower than that of gasoline in the domestic refinery market, it is advantageous in terms of fuel efficiency and efficiency.

Since these diesel engines contain nitrogen oxides (NOx) and particulate matter (PM), which cause air pollution, are contained in the exhaust gas, they must be equipped with a soot reduction device in order to reduce them. Diesel particulate filter (DPF) and diesel oxidation catalyst (DOC) are typical examples of the soot reduction apparatus.

Among them, Diesel Particulate Filter (DPF) is a technique for reducing particulate matter which is currently the most efficient and practical approach. The diesel particulate filter is a technique for collecting particulate matter emitted from a diesel engine as a filter, then burning it (regenerating) and collecting the particulate matter again, thereby reducing the soot by 80% or more.

Also, since the DOC (Disel Oxidation Catalyst) is basically the same technology as the oxidation catalyst (two-way catalyst) used before the development of the three-way catalyst in the gasoline engine, the technology effect and performance have already been proved. The oxidation catalyst functions to remove hydrocarbons and carbon monoxide using oxygen in the exhaust gas due to the catalytic effect of platinum (Pt) and palladium (Pd).

However, the diesel particulate filter and the diesel particulate filter using the diesel oxidation catalyst are obstacles to commercialization of durability and economical efficiency. In addition, as the particulate matter is trapped in the filter, back pressure is applied to the engine, and thus, the output and the fuel consumption rate are sacrificed somewhat, and a technique to minimize this is needed.

In addition, there is a problem that the power generating device installed inside the building is completely vulnerable to noise because the outside is completely open. In addition, there is a problem that a vibration structure that reduces vibrations generated by the generator and a vibration structure that reduces vibration transmitted to the generator due to an external force such as an earthquake There is a need for a technique for improving the dustproof structure and preventing the complaints caused by noise and vibration.

And certain features shown in the drawings are to be enlarged or reduced or simplified for ease of explanation, and the drawings and their components are not necessarily drawn to scale. However, those skilled in the art will readily understand these details.

FIG. 1 is a perspective view showing a power generating apparatus according to an embodiment of the present invention, and FIG. 2 is a side sectional view showing the inside of the power generating apparatus shown in FIG. 1 from the side.

1 and 2, a power generating apparatus according to an embodiment of the present invention includes a generator installed therein, an intake duct for introducing air into the upper side, and an exhaust duct for exhausting exhaust gas to the upper side A plurality of dust collecting apparatuses provided at an end of the enclosure main body for discharging the exhaust gas from the generator to filter foreign substances contained in the exhaust gas and reduce exhaust noise; And an anti-vibration device for preventing vibration from being transmitted between the enclosure main body and the mounting surface.

The enclosure main body is formed in a substantially rectangular parallelepiped shape, and includes an engine required for a power generation facility, a fan and a radiator for cooling the engine, an intake / exhaust manifold, and the particulate reduction device. In addition, air is introduced into the outside of the enclosure body through the intake duct formed on the upper side, and the introduced air is used for combustion or heat radiation of the engine, and exhaust air burnt in the engine is exhausted to the outside through the exhaust duct . At this time, though not shown in the drawing, the intake duct or the exhaust duct may be provided with a separate blowing fan to smooth out the air.

The inside of the enclosure main body is divided into at least two spaces. A partition wall is installed in the inside of the enclosure main body so as not to be mixed with air introduced into the engine through the exhaust gas through the exhaust gas reduction device. Accordingly, the operation chamber in which the engine is disposed is located on one side of the partition, and the exhaust chamber in which the exhaust gas combusted in the engine is exhausted is located on the other side of the partition. The exhaust chamber communicates with the exhaust duct to exhaust the exhaust gas to the outside.

Fig. 3 is a cross-sectional view showing the particulate filter of the power generation apparatus shown in Fig. 2, and Fig. 4 is a sectional view partially showing the first filtration unit of the particulate filter shown in Fig.

3 and 4, the exhaust gas recirculation system 100 includes an inlet 111 through which exhaust gas combusted and exhausted from an engine of a generator is introduced, and exhaust gas supplied from the inlet 111 is introduced into the exhaust A main body part 110 formed with a filtration space 112 to be filtered by the filtration space 112 and having a discharge port 113 for discharging the filtration space 112 to the outside, A first filtering part 120 disposed inside the main body part 110 for forming a spiral vortex in the exhaust gas to centrifugate the foreign substances contained in the exhaust gas, A diesel oxidation catalyst (DOC) 140 for separating foreign substances from the exhaust gas passing through the exhaust gas purification unit 120 and separating particulate matter contained in the exhaust gas before or after the diesel oxidation catalyst 140 The diesel particulate filter (DPF) 150 and the first filtration portion 12 0), and a second filtering unit 130 for centrifugally separating the foreign substances.

The smoke reduction device 100 may be applied to a vehicle in which a general diesel engine is used. Also, the positions of the diesel oxidation catalyst 140 and the diesel particulate filter 150 may be interchanged depending on circumstances.

First, the main body 110 stores therein the first filtration part 120, the second filtration part 130, the diesel oxidation catalyst 140, and the diesel particulate filter 150 in the filtration space 112 do. Of course, the main body 110 is formed so that one side of the main body 110 can be opened and closed so that each component can be detached.

The exhaust gas supplied into the main body 110 through the inlet 111 is subjected to a plurality of filtration processes until it is discharged to the outside through the outlet 113. The first filtration unit 120 functions to centrifugally filter relatively large particles mixed in the exhaust gas.

4, the first filtration unit 120 includes a supply nozzle 121 connected to the inlet 111 to increase the back pressure of the exhaust gas, A housing 122 formed in a cylindrical shape so as to allow the exhaust gas to swing, a collecting part 123 storing foreign substances centrifuged while descending the inner circumferential surface of the housing 122, And an exhaust nozzle 124 for exhausting the exhaust gas to the outside of the housing 122.

The supply nozzle 121 preferably has a circular or quadrangular cross section corresponding to the shape of the inlet 111, and is preferably formed so that the sectional area gradually decreases along the direction in which the exhaust gas flows. The supply nozzle 121 gradually decreases in cross sectional area so that the back pressure of the exhaust gas burned in the generator engine can be maintained within the set range, and the range of the decrease is the exhaust gas pressure of the engine, the type of the engine, The size of the filtration unit 120 can be adjusted. Therefore, the supply nozzle 121 can be changed depending on the use or the scale.

The housing 122 has a cylindrical shape, and the lower portion of the housing 122 is formed in a lowered shape with a diameter decreasing gradually toward the lower portion. The housing 122 is not connected to the side surface center of the housing 122 so that the exhaust gas received from the supply nozzle 121 rotates around the inner circumferential surface to form a vortex, And is connected to an eccentric position displaced from a virtual center line of the housing 122. Therefore, the direction of rotation of the exhaust gas supplied through the supply nozzle 121 is determined for the vortex, and the exhaust gas is rotated inside the housing 122 by its own back pressure.

At this time, the inclined face 122a is formed so that the diameter is uniformly decreased in the lower side of the housing 122, the rotational speed of the foreign substance contained in the exhaust gas is increased, and the pressure of the exhaust gas increases along the inclined face 122a The foreign matter flows into the collecting unit 123. And the exhaust gas is discharged from the housing 122 through the discharge nozzle 124.

The collecting part 123 may be disposed inside or outside the main body 110, but is preferably disposed outside the main body 110. At this time, a communication part 125 for connecting the housing 122 and the collecting part 123 is provided. The communication part 125 is adjustable in length and flexibly bent so as to prevent foreign matter discharged from the housing 122 from being discharged to the housing 122 again. In addition, a plurality of the discharge units may be connected to each other according to the discharge size of the foreign matter, and the communication unit 125 may be branched from the housing 122 to a plurality of lines. The foreign body inside the collecting part 123 can be separated and discharged from the inside of the enclosure main body (see FIG. 2) 210 by the operator.

Fig. 5 is a sectional view partially showing the second filtration part of the diesel particulate filter shown in Fig. 3, and Fig. 6 is a schematic view schematically showing the inside of the second filtration part of the diesel particulate filter shown in Fig.

5 and 6, the discharge nozzle 124 is formed as an oblique surface 124a so that the shape of the one end portion corresponds to the oblique surface 122a of the housing 122. As shown in FIG. Accordingly, the exhaust gas flows along the inclined surface 122a of the housing 122, and then the foreign substance is discarded and is introduced into the oblique surface 124a and is discharged to the outside through the discharge nozzle 124. [ At this time, the oblique surface 124a is formed to increase the cross-sectional area along the flow direction of the exhaust gas. This serves to compensate for the increase in back pressure due to the inclined surface 122a of the housing 122.

The second filtering unit 130 is disposed in the middle of the discharge nozzle 124. The second filtering unit 130 includes a blocking plate 131 having a plurality of through holes 133 to be a path of exhaust gas passing through the exhaust nozzle 124 and a through hole 133 formed on the blocking plate 131, Shaped separating member 134 connected to the coupling nozzle 132 protruded around the center hole 133 and centrifugally separating foreign substances while forming an eddy gas supplied to the through hole 133.

The blocking plate 131 functions to shield the inside of the exhaust nozzle 124 and exhaust the exhaust gas through the through hole 133. At this time, the separating member 134 receives the exhaust gas before the through hole 133 and centrifugally separates foreign matter from the inside. The separating member 134 is formed such that the diameter of the other end where the exhaust gas is exhausted is formed to be larger than the diameter of the one end to which the exhaust gas is introduced and the other end of the separating member 134 is coupled to the through hole 133 do. Further, a coupling nozzle 132 protrudes on the upper surface of the separating member 134 and is coupled to the other end of the separating member 134. Thus, the secondarily centrifuged foreign matter is discharged through the one end of the separating member 134 and discharged to the collecting unit 123.

It is desirable that the sum of the areas of the through holes 133 is larger than the area of the inlet 111 so as to prevent the pressure inside the housing 122 from increasing beyond the set range.

When the exhaust gas passes through the second filtration unit 130, relatively large particles of foreign matter are filtered and discharged, so that the diesel oxidation catalyst 140 and the diesel particulate filter 150 can filter only a relatively small amount of foreign matter And thus the service life of the diesel oxidation catalyst 140 and the diesel particulate filter 150 can be increased. In addition, when the diesel particulate filter 150 is heated to burn out the remaining foreign matters, only a small foreign substance is oxidized, so that the regeneration effect is remarkably increased. Further, the NOx or particulate matter PM contained in the exhaust gas There is an effect that the emission can be reduced.

The dustproof device can be applied not only to the power generation device of the present invention but also to a power plant, a distribution panel, a motor control panel, a solar power generator, an inverter, a connection panel, and the like.

7 to 11, the vibration damping device of the power generating apparatus of the present invention includes a first support plate 310, a second support plate 310 spaced apart from the first support plate 310 and supporting a bottom surface of the enclosure body 210, A dustproof spring 330 interposed between the first support plate 310 and the second support plate 320 to reduce transmission of vibration in the vertical direction, 310 and the outer circumferential surface of the second support plate 320 at a predetermined interval to maintain a space between the first support plate 310 and the second support plate 320 and transmit vibration in a horizontal or vertical direction A first fixing plate 351 coupled to a lower surface of the first supporting plate 310 and fixed to the mounting surface of the first fixing plate 351 and a second fixing plate 351 protruding from the first fixing plate 351, And a first cover plate 353 having a cylindrical shape and disposed so as to surround the periphery of the first cover plate 353 A second fixing plate 361 coupled to an upper portion of the second supporting plate 320 and fixed to a bottom surface of the enclosure main body 210 and a second fixing plate 361 protruding from the second fixing plate 361, The second cover 360 includes a cylindrical second shielding plate 362 inserted into the first shielding plate 350 and a second cover 360 inserted into the first shielding plate 353 to selectively contact the elastic support 340 And an elastic pad 370 disposed thereon.

Here, the first support plate 310 and the second support plate 320 prevent vibrations from being transmitted from one side to the other, and conversely, transmission of vibration from the other side to the one side can be prevented.

The first support plate 310 is installed on the first fixing plate 351 and the first fixing plate 351 is installed on the mounting surface. The mounting surface may be another structure fixed to the ground or the ground. At this time, an installation groove 352 may be formed in the first fixing plate 351 so that the first supporting plate 310 can be installed. The installation groove 352 prevents the first support plate 310 from being separated from the first support plate 310 in the horizontal direction and facilitates the installation of the first support plate 310 to provide. A first coupling step 311 is formed on the first support plate 310 so that the dust-proof spring 330 can be inserted and fixed.

The second support plate 320 is disposed on the upper portion of the first support plate 310 and supports the bottom surface of the enclosure body 210. The upper surface of the second support plate 320 contacts the inner bottom surface of the second fixing plate 361 to elastically support the second fixing plate 361 to support the outer case body 210. A second coupling protrusion 321 is formed at a lower portion of the second support plate 320 so that the vibration springs 330 can be inserted and fixed.

9, the anti-vibration spring 330 provides elastic restoring force between the first support plate 310 and the second support plate 320 in the vertical direction. Accordingly, the structure coupled to the upper portion of the second fixing plate 361 is elastically disposed on the mounting surface by the elastic restoring force to absorb vibration. Also, the anti-vibration spring 330 can provide a predetermined restoring force against an external force generated in the horizontal direction.

10, the elastic supporting part 340 provides an elastic restoring force in a vertical direction together with the vibration-proof spring 330, and either one of the first supporting plate 310 and the second supporting plate 320 So that the restoring force can be provided in the horizontal direction by providing the reaction force corresponding to the force that the other one is inclined or horizontally spaced apart.

For example, when an external force is applied to the upper part of the second cover part 360 and an external force is applied from the left side of the first cover part 350, the second fixing plate 361 is pressed downward, The first cover part 350 relatively moves to the right relative to the second cover part 360. [

A virtual axis connecting the opposite ends of the anti-vibration spring 330 is inclined while being bent, and the elastic supporting part 340 is also deformed into an inclined shape and is compressed while the left side of the elastic supporting part 340 is horizontal And the right side of the elastic supporting portion 340 is disposed to be spaced apart from the elastic pad 370 relatively. The second shielding plate 362 is compressed with the first shielding plate 353 around the elastic pad 370 to form a restoring force due to the elastic force of the elastic pad 370. Therefore, a reaction force is generated corresponding to the external force applied in the vertical direction and the horizontal direction, and a restoring force is formed not only in the vertical direction but also in the horizontal direction.

For example, when an external force is concentrated on the left upper end of the second cover portion 360, the second fixing plate 361 is pressed downward in the left direction, And the right upper side is inclined to the raised shape (not shown).

Then, the anti-vibration spring 330 is compressed in the vertical direction, and the elastic supporting portion 340 disposed on the left side in the drawing is also compressed while being compressed to press the inner peripheral surface of the second guide groove 371 formed on the inner side of the elastic pad 370 Respectively. At this time, the elastic supporting portion 340 arranged on the right side is relatively tensioned and a reaction force for preventing the distance between the first supporting plate 310 and the second supporting plate 320 from being distanced from the distance of the elastic supporting portion 340 . Therefore, the resilient supporting portion 340 disposed on the left side of the vibration springs 330 in the vertical direction or the horizontal direction is subjected to a reaction force to bend the elastic supporting portion 340, and the elastic supporting portion 340 disposed on the right side is in the unfolded state A reaction force to return to the circular state acts to provide a vertical or horizontal restoring force that the first support plate 310 and the second support plate 320 can return to each other.

When the external force acts only in the horizontal direction, the anti-vibration spring 330, the elastic supporting portion 340, and the elastic pad 370 can act together in a direction opposite to the external force to provide a restoring force in the horizontal direction have. This is because when the external force is transmitted to the first cover part 350 and the first cover part 350 is pressed in the left direction, the first support plate 310 fixed to the first fixing plate 351 can be prevented from being damaged A reaction force is formed again in the opposite direction by the spring 130 and the elastic supporting portion 340 and a reaction force is generated between the first shielding plate 353 and the second shielding plate 362 by the elastic pad 370 While providing resilience.

Since the restoring force of the vibration-proof spring 330 and the resilient supporting portion 340 can block the flow of vibration and prevent the first supporting plate 310 and the second supporting plate 320 from being separated from each other, The anti-vibration device 300 can prevent the structure from falling down, that is, falling or detaching from the mounting surface.

Referring to FIG. 11, a fixing hole 364 is formed at the center of the second fixing plate 361. A female screw is formed in the fixing hole 364, and the adjusting part 380 is coupled to be vertically reciprocated. The adjusting unit 380 moves in the vertical direction on the fixing hole 364 to selectively press the second supporting plate 320. The compressive stress between the first support plate 310 and the second support plate 320 is controlled according to the force that the regulating unit 380 presses the second support plate 320, There is an effect that can adjust the level.

For example, when the first support plate 310 and the second support plate 320 are brought close to each other by rotating the regulating unit 380, the width between the first cover unit 350 and the second cover unit 360 is narrow The resilient restoring force of the anti-vibration spring 330 and the resilient supporting portion 340 increases, and the horizontal structure of the structure can be adjusted together with the other anti-vibration devices installed on the bottom surface of the enclosure main body 210.
