Description

Containerized power plant

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to container-type power plant technology, and more particularly to compressed air required for engine combustion during operation of the engine to be introduced directly from the outside through a supercharger, thereby operating the temperature environment in a narrow enclosure space. The present invention relates to a new container-type power generation plant having a power generation unit which can be advantageously controlled and a main control unit which improves worker safety.

Generally, a generator is a generator facility that converts the output of an engine into electric power. In recent years, CPP is not installed in a large-scale house, but a modular power plant (CPP) is manufactured in a 40-foot container which is a modular unit for each function, and then assembled and installed in a prepared place by transporting it in a container transport vehicle (CPP). : containerized power plant is known. This does not require a separate generator house, and only after the foundation work on the ground, there is an advantage such as to shorten the construction period because the necessary units are transported and installed.

1 shows a schematic bird's eye view showing an example of such a container-type power plant 1 in the prior art. As shown, this containerized power generation plant 1 includes an engine and a generator and includes a plurality of power generation units 10 for converting the engine output into electric power. And a plurality of auxiliary units for supplying, controlling and monitoring the fuel oil required for the power generation unit 10. These auxiliary units include a main control unit 200 and a fuel oil storage tank 3 as shown. , Pump unit 4, fuel oil supply unit 5, and the like.

Typically, as shown in FIG. 2, the power generation unit 10 includes an engine 11, a generator 12, and a control panel 13, which is an electric device, arranged inside a container-shaped enclosure 16. Has a structure. Exhaust gas of the engine 11 is discharged through the silencer 14 communicated with the outside from the top of the enclosure (16). The engine is cooled by the radiator 15 installed on the enclosure 16. The air in the inner space of the enclosure 16 is discharged to the outside through the outlet 18 installed on the upper side of the side on which the control panel 13 is installed after the outside air is introduced through the inlet 17 installed on the engine side.

In the conventional power generation unit 10 having such a structure, the air required by the engine 11 is supplied from the interior space of the enclosure 16, but the air heated by the engine operation inside the narrow enclosure 16 is supplied with electricity. Since the device has to flow out of the control panel 13, which is a device, there is a problem that it may pose a danger to the normal operation of the control panel 13. Furthermore, although the noise of the engine can be reduced to some extent by the enclosure 16 wall, since the inlet 17 and the outlet 18 of the power generation unit 10 are still open, the noise reduction efficiency is also increased. Not so good. In addition, since the control part of the low voltage part for controlling the operation of the apparatus of each part and the high voltage control part for power distribution are arranged unintentionally in the main control unit, the operator simply approaches the main control unit only for the control operation. Even if it does, the risk of contact with the high-voltage part was a lot of problems in the work stability.

Therefore, it is possible to advantageously control the flow of heat and air for optimal operation of each unit in a narrow, largely enclosed space, while reducing noise and ensuring operator safety. There is still a desperate need for structure.

The present invention has been invented to improve the structure of the above-described conventional containerized power plant and to provide various additional advantages.

Its purpose is to provide a new containerized power plant that makes it possible.

The present invention provides a new container-type power plant that can improve engine efficiency by ensuring that the supercharger in the power generation unit is supplied with a relatively low temperature air through a separate intake air filter including a silencer. To provide that purpose.

In addition, the present invention structure the inlet and outlet of the power generation unit without disturbing the flow of air The aim is to provide a new containerized power plant that can maximize the noise reduction effect.

In addition, in the main control unit 200 of the present invention, even if the operator approaches the arrangement of the low voltage control unit for controlling the operation of the device of each part and the high voltage control unit for power distribution without the risk of contact with the high voltage portion The aim is to provide a new container-type power plant that can only work, thereby improving work stability.

In another aspect, the present invention provides a container-type power plant that separates the engine and the generator that generates heat from the control panel to reduce noise and to operate the control panel normally without heat effect through an air conditioner installed in the space where the control panel is located. It is for that purpose.

As shown in Figures 3 and 4, the container-type power generation unit provided according to one aspect of the present invention is one of the units constituting the container-type power generation plant, the output of the engine to the power This unit is responsible for converting and outputting.

The power generation unit 100 includes a control panel 130 for controlling the engine 110 and the generator 120 and the respective parts, power transmission, and device protection in the container-type enclosure 160. 140, a radiator 150, an inlet 170, an outlet 180, and an air inlet 190.

The engine 110 is preferably a diesel engine using an oil fuel such as diesel oil, but the engine 110 does not necessarily need to be a diesel engine. Although described below as an engine, it is pointed out that this is merely for convenience of description and does not limit the technical scope of the present invention.

The engine 110 of the power generation unit 100 includes a supercharger 112 installed on the engine 110 inside the enclosure 160 to supply compressed air to the combustion chamber of the engine 110. The supercharger 112 is a device for compressing air by the rotation of the turbine, for example, may be a turbocharger or a supercharger.

The air inlet 190 is a means for communicating the supercharger 112 with the outside of the enclosure 160 so that air outside the enclosure 160 can be directly supplied to the supercharger 112, the details of which are shown in FIG. 5. As shown, the air inlet 190 consists of a duct 192 which communicates with the outside and the interior of the enclosure at the upper side of the enclosure 160, the end of the duct extending inside the enclosure 160 is connected to the tube (196) ) Has a structure in communication with the supercharger 112. The air inlet 190 may further include a porous split for filtering noise and removing impurities from the outside air. The porous split may be, for example, in the form of a plurality of overlapping porous networks in which fine holes are formed. 10 (a) to 10 (f) show examples of the porous split structure as a filter of the air inlet 190. Detailed drawings. The filter 194 may be, for example, a form in which a plurality of porous networks having fine holes are formed.

In this way, the air inlet 190 supplies the outside air to the engine 110 via the supercharger 112, which has the advantage of giving the designer freedom to control the air flow inside the power generation unit 100 freely. Because, as already mentioned while describing the conventional power generation unit 10 shown in Figure 2, in the prior art, the inlet port for the outside air flows into the enclosure had to be installed on the engine side, which in turn, the air is discharged from the enclosure to the outside This is because it imposes a limit that the outlet can be installed on the control panel side, which is a heat sensitive electric device.

According to one embodiment of the invention, as shown in Figure 4, along the longitudinal direction of the enclosure 160 of the power generation unit 100, the engine 110, the generator 120, and the control panel 130 in turn In this case, the inlet 170 for introducing air from the outside of the enclosure 160 to the inside is disposed on the control panel 130 side, and the outlet 180 for discharging air from the inside of the enclosure 160 to the outside is provided. It is disposed on the engine 110 side.

Accordingly, as illustrated in FIG. 6B, external air having a relatively low temperature can pass through the control panel 130, and the internal air heated by the engine operation is discharged from the outlet 180 on the engine side. Can be discharged quickly. This is because in the conventional power generation unit 10, as shown in FIG. 6A, internal air having a relatively high temperature is discharged through the control panel 13, while external air required for engine operation is discharged to the engine side. Contrast with the structure flowing through the inlet (18).

In detail, as clearly shown in FIG. 4, the inlet 170 and the outlet 180 are forced flows of air in the

ducts

172 and 182 and the

ducts

172 and 182, respectively, which become air flow passages. One or

more fans

174, 184, and

porous splits

176, 186 installed in the

ducts

172, 182. The

porous splits

176 and 186 are similar to the filter 194 for reducing noise while removing impurities from the outside air provided in the air inlet 190 mentioned above. The network may be of a plurality of overlapping forms. Accordingly, while the air flows through the

porous splits

176 and 186, impurities in the external air are removed, and noise generated in the enclosure 160 can be greatly reduced.

9 shows the main control unit 200 with improved working stability of the present invention. The control equipment panel installed inside the main control unit 200 includes a low voltage line region 210 and 210 'for control and monitoring, which are relatively low voltage parts, and an output unit 220 and 220' for outputting power to the outside. The high

voltage line regions

230 and 230 ′, which are high voltage parts for receiving and distributing the power output from the

transformers

240 and 240 ′ and the generator, may be sequentially disposed. Accordingly, the low

pressure line regions

210 and 210 ′ for controlling and monitoring the operation of each unit and the high

pressure line regions

230 and 230 ′ for power distribution may be separated from each other left and right. This allows the operator to minimize the chance of contacting the high-voltage line regions 230 and 230 'which may harm the human body when approaching the main control unit 200 for control work, thereby improving work stability. You can.

On the other hand, as the power generation capacity of the power plant increases, it is necessary to install a plurality of control equipment panels installed in the main control unit 200. In this case, according to the present invention, the main control unit 200 is provided as two control facility panels 22 and 22 'disposed to face each other, and an operator works between the two control facility panels 22 and 22'. It is desirable to have a size that provides space for doing so. In this configuration, as the power plant output increases, the advantage is that the minimum space can be used without increasing the size of the main control unit 200. (Arrow U shows the direction in which the worker moves for work. )

Meanwhile, a base frame 165 including a lifting lug having a 'c' cross sectional structure may be installed below the enclosure 160. This is for reinforcing the floor as well as for safe transportation of the power generation unit 100 amounting to about 56 tons.

In addition, it is preferable to separate the space between the engine 110 and the generator 120 is installed and the space in which the control panel 130 is installed with a fluid membrane that can be opened and closed. This is to block the noise of the engine 110 or the generator 120 when the operator enters the enclosure 160 to operate the control panel 130.

At this time, the air conditioner may be installed in the space on the side of the control panel separated by the fluidized membrane. This is to prevent the temperature of the space on the control panel side including a plurality of electrical devices from excessively rising to prevent damage or malfunction of each electrical apparatus, and is selectively installed according to the region in which the power generation unit 100 is installed. .

In addition, as shown in FIG. 9, the main control unit 200 controls the low voltage control unit 210 and the output unit 220 for controlling each power generation unit 100, the water distribution of the power, and the device protection of the high voltage control unit 230. ) Is disposed to the left and right of the transformer 240. Furthermore, in the case of the eight standard model of the power generation unit 100, when configuring the main control unit 200, the low voltage controller 210 is a low voltage controller 210 ′, and the high voltage controller 230 is a high voltage controller 230. ') Install symmetrically to face each other. Accordingly, when the operator enters the main control unit 200 to control each power generation unit 100, the control operation can be performed only in the low voltage control unit 210 without contacting the high voltage control unit 230. Not only can it be improved, but it can also minimize the working line, resulting in the effect of saving one 40-foot container compared to the prior art. Therefore, the site of the plant can be reduced and the space utilization can be maximized, and the remote centralized control system can be arranged to maximize the space utilization.

In other words, the main control unit 200 is a relatively low voltage control unit 210 and the output unit 220 for outputting power to the outside and the high voltage control unit 230 for transmitting the power output from the transformer 240 and the generator ) May be arranged one after the other. Accordingly, the control unit 210 for controlling the operation of each unit and the high voltage control unit 230 for water distribution of power may be separated from each other left and right. This makes it possible to minimize the opportunity for the operator to contact the high-voltage line area that may harm the human body when approaching the main control unit 200 for the control work, it is possible to improve the work stability.

Although the present invention has been described through specific embodiments, various modifications are possible to those skilled in the art by referring to and combining various features described herein. Therefore, it is pointed out that the scope of the present invention should not be limited to the described embodiments, but should be interpreted by the appended claims.
