Description

Monitoring system of generator with particulate exhaust reduction device}

The present invention relates to a monitoring system for an emergency generator equipped with a smoke reduction device, and particularly to a generator monitoring system capable of monitoring the lifespan of the smoke reduction device, including the state before and after driving the generator.

In general, demand for diesel engines continues to increase because they are capable of operating at high efficiency and high output. In addition, in the domestic oil refining market, diesel is cheaper than gasoline, so it has superior advantages in terms of fuel efficiency and efficiency.

Since the diesel engine emits nitrogen oxides (NOx) and particulate matter (PM), which cause air pollution, in the exhaust gas, it is mandatory to install a smoke reduction device to reduce them. Representative examples of such exhaust reduction devices include diesel particulate filter (DPF) and diesel oxidation catalyst (DOC).

Among these, Diesel Particulate Filter (DPF) is currently the most efficient and practical technology for reducing particulate matter. Diesel particulate filter is a technology that repeats the cycle of collecting particulate matter emitted from a diesel engine through a filter, burning (regenerating) the particulate matter, and then collecting the particulate matter again, and is effective in reducing exhaust emissions by more than 80%.

In addition, Diesel Oxidation Catalyst (DOC) is basically the same technology as the oxidation catalyst (two-way catalyst) technology used before the development of three-way catalysts in gasoline engines, so its technical effectiveness and performance have already been proven. . The oxidation catalyst functions to remove hydrocarbons and carbon monoxide using oxygen in the exhaust due to the catalytic effect of platinum (Pt) and palladium (Pd).

However, the durability and economic efficiency of exhaust reduction devices using diesel particulate filters and diesel oxidation catalysts are obstacles to their practical use. In addition, as particulate matter is collected in the filter, back pressure is applied to the engine, which somewhat sacrifices power and fuel consumption, and it is necessary to supplement technology to minimize this.

이상의 배기가스 온도가 필요하나 무부하 운전으로는 150

정도까지만 배기가스 온도가 상승하기에 추가적인 버너 및 전기히터를 통한 가열 작업이 필요하여 구조가 복잡해지며 화재의 위험 및 유지비 상승 등의 문제가 발생한다.The existing DPF type smoke reduction device is 300

Exhaust gas temperature above 150°C is required, but no-load operation requires 150°C.

As the exhaust gas temperature rises only to a certain extent, heating work using additional burners and electric heaters is required, which complicates the structure and causes problems such as the risk of fire and increased maintenance costs.

In addition, work must be done to collect the smoke generated when the generator is running and to regenerate the collected smoke. However, for load operation of the emergency generator, a problem arises in that the load must be turned on after a power outage, so exhaust gas required for smoke regeneration work through no-load operation has arisen. Since the gas temperature cannot be raised, only collection is performed without regeneration, which shortens the regeneration cycle of the exhaust reduction device. If not managed, pressure increases due to filter clogging, and there is a possibility of an accident in which power cannot be supplied at critical times due to damage to the engine. there is.

In addition, since it is installed on the ceiling of the generator room, regeneration work requires detaching and attaching the exhaust emission reduction device and connecting it to the regeneration device to perform the regeneration work. To carry out the work, professional manpower and equipment are brought in for maintenance and maintenance. A cost increase occurs.

In existing smoke reduction devices, ceramic filters can become clogged due to excessive collection, which can cause failure of the generator and flue due to back pressure problems when the generator is running. To prepare for back pressure problems, additional devices such as bypass valves or rupture disks must be installed, which incurs additional financial costs.

On the other hand, an emergency generator refers to a generator that is not normally used and is used to supply the necessary power to the load by responding to commercial power when an emergency situation such as a power supply interruption occurs. A diesel engine-type emergency generator is generally used.

Unlike generators that operate all the time, these emergency generators automatically start and supply power only in emergencies, so they must always be maintained in a normal operating state to prepare for emergency situations that may occur at any time.

If the emergency generator does not operate normally in an emergency and cannot supply power, the interruption of power supply will be prolonged, increasing the damage from various accidents due to the interruption of power supply.

To this end, regular inspection of the emergency generator is essential, and currently, managers regularly operate the emergency generator to check whether the emergency generator operates normally.

Conventional technologies can check the status of these emergency generators through sensors and monitor the startup status during test runs, but the configuration of most monitoring systems is displayed in a location close to the generator, and field workers must frequently move directly to check. There is a need, and not only is it impossible to determine which part of the problem is causing the problem, but even if the engine starts normally, there is a problem that it is impossible to monitor problems due to a decrease in power generation efficiency or gas reduction efficiency of the exhaust gas reduction device.

The present invention was devised to solve the above problems, and is equipped with a smoke reduction device that allows remote monitoring and control of the status before and after operation of the generator and the lifespan of the smoke reduction device through a PC or portable device from a distance. The purpose is to provide a monitoring system for an emergency generator.

A monitoring system for a generator equipped with a smoke reduction device according to the present invention to achieve the above object is configured to include a generator driven in the event of a power supply interruption or emergency situation, and one side of the generator to monitor exhaust gases combusted and discharged from the engine. An exhaust gas abatement device that receives supply and separates and removes organic compounds contained in the exhaust gas, a monitoring unit that remotely receives and manages the operating status before and after driving of the generator and the status of the exhaust gas abatement device, and the generator And a data communication unit that transmits status information of the exhaust emission reduction device to the monitoring unit, wherein the monitoring unit is a general equipment that synthesizes the status of the entire generator equipment and displays the status of each installation configuration in red, yellow, and green. The condition control unit and the vibration, pressure, noise, and temperature of the exhaust reduction device, including each facility of the generator, are measured, and when a value exceeding the standard value is measured in any facility, the abnormal state of the facility is visually expressed to the user. A visualization representation unit that allows the user to intuitively recognize abnormal parts, an operation data statistics unit that displays data accumulated during operation of the generator's operating time, power generation, and exhaust gas for each set period, and a periodic display of the fuel amount of the generator. A fuel check unit that checks and displays the remaining fuel amount of the current power generation equipment, and a smoke reduction device check unit that checks the filter amount of the smoke reduction device by receiving temperature and pressure data and calculates and displays the replacement cycle and remaining amount. , It is characterized by including an emergency generator drive trend unit that allows the generator to check the operation trend of the facility by listing the power generation data operated for a certain period of time by time and checking the power generation efficiency of the generator and the data of each sensor.

The monitoring system for a generator equipped with a smoke reduction device according to an embodiment of the present invention has the following effects.

First, the status before and after operation of the generator and the lifespan of the exhaust reduction device can be remotely monitored and controlled through a PC or portable device from a distance.

Second, the reliability of the operation of the generator can be improved by monitoring the status of the emergency generator, which must operate normally in an emergency, in real time.

Third, by checking the smoke reduction device in real time, the operating efficiency of the emergency generator can be increased by early preventing a decrease in gas and power generation efficiency caused by a decrease in filter efficiency.

Fourth, by determining the status and trends of emergency generator equipment through hourly operation trends of the emergency generator, it is possible to effectively predict the lifespan of the device and when inspection is required.

An operation data statistics unit 330 that displays by period, a fuel check unit 340 that periodically checks the fuel amount of the generator 100 and displays how much fuel is currently remaining in the power generation facility, and the generator 100 ), which checks the filter amount of the smoke reduction device (200), which reduces the amount of gas generated while the generator is running and improves power generation efficiency, by receiving temperature and pressure data, and calculates and displays the replacement cycle and remaining amount. The smoke reduction device check unit 350 and the generator 100 are operated and the power generation data operated for a certain period of time are listed by time to check the power generation efficiency of the generator 100 and the data of each sensor unit to check the operation trend of the facility.

Figure 2 is a schematic configuration diagram of the exhaust emission reduction device of Figure 1.

As shown in FIG. 2, the exhaust gas reduction device 200 has an inlet 210 through which exhaust gas combusted and discharged from the engine of the generator 100 flows, and exhaust gas supplied from the inlet 210. A cyclone unit 220 that separates and collects organic compound particles contained in the exhaust gas in two stages using rotational inertial force, and receives the exhaust gas that has passed through the cyclone unit 220 to collect the particles contained in the exhaust gas. A metal ceramic mixing filter unit 230 for separating particulate matter, an outlet 240 for discharging exhaust gas from which particulate matter is separated through the metal ceramic mixing filter unit 230 to the outside, and the cyclone unit 220 ) and includes a dust collection unit 250 that is configured at the bottom of the cyclone unit 220 to collect organic compounds collected through the cyclone unit 220.

In addition, it further includes a pressure sensor (not shown) installed in the inlet 210 and the outlet 240, and the pressure information of the inlet 210 and the outlet 240 is transmitted through the pressure sensor to reduce the smoke. It is possible to analyze the blockage of the metal-ceramic mixing filter unit 230 by receiving the pressure from the device check unit 350 and comparing the pressure difference between the inlet 210 and the outlet 240.

Here, the exhaust gas supplied into the cyclone unit 220 through the inlet 210 undergoes a plurality of filtration processes until it is discharged to the outside through the outlet 240. Among these, the cyclone unit 220 performs the function of separating relatively large particles of foreign matter mixed in the exhaust gas in two stages, primary and secondary, by centrifugation and collecting them in the dust collection unit 250.

The dust collection unit 250 is a part that collects dust centrifuged through the cyclone unit 220 and is disposed inside or outside the smoke reduction device 200. In addition, when the dust collection unit 250 is configured inside the smoke reduction device, a door is provided on the lower side to remove dust inside the dust collection unit 250, and when the dust collection unit 250 is configured outside the smoke reduction device, the dust collection unit 250 It is designed to be detachable so that it can be replaced.

Here, as shown in FIGS. 4 and 5, the cyclone unit 220 includes an inlet 221 that guides the exhaust gas discharged from the generator 100 to flow into the interior through the inlet 210, and A cylindrical cylinder part 222 having an internal space so that the exhaust gas flowing in through the intake port 221 can flow externally, and from the inner space of the cylinder part 222 through the intake port 221. A cone portion 223 that primarily separates organic compounds contained in the exhaust gas by rotating the exhaust gas flowing into the inner space of the cylinder portion 222 by an external swirling flow, and an inner space of the cylinder portion 222 It is installed in the same form as the cylinder part 222, passes the distal end of the cone part 223, receives the first separated exhaust gas, escapes to a low pressure area along the central axis of the rotation flow, and is raised by the internal rotation flow. A filter 224 that secondarily separates and discharges the intermediate particles contained in the exhaust gas, a passage portion 225 that passes the particles of the exhaust gas that are secondarily separated and discharged from the filter 224, and the source. It includes a discharge part 226 that goes down along the cross section of the weight part 223 and discharges particles and organic compounds with a higher specific gravity than the exhaust gas to the dust collection part 250 due to dust collision and centrifugal force due to external rotational flow. This is done.

In addition, between the dust collection unit 250 formed at the bottom of the cyclone unit 220, there is a discharge nozzle 251 so that foreign substances including organic compounds separated through the cyclone unit 220 are collected into the dust collection unit 250. It is equipped with

The cylinder portion 222 has a cylindrical shape, and is formed on the lower side in a shape where the diameter steadily decreases toward the bottom. The exhaust gas flowing into the cylinder unit 222 through the intake port 221 rotates along the inner circumferential surface, thereby forming a vortex.

As shown in FIG. 6, the filtering unit 224 is located at the center of the cyclone unit 220, and the exhaust gas flowing in from the inlet pipe 224a is distributed through a plurality of small cone-shaped cyclones arranged at the same height. As it passes through (224b) in parallel, it forms a small swirling flow and causes high-speed rotation, which serves to secondaryly separate coarse particles.

The metal-ceramic mixed filter unit 230 consists of a ceramic filter with an internal lattice structure and a metal filter formed along the flow direction of the exhaust gas in a certain ratio to prevent pressure increase, collects particles in the exhaust gas and regulates the air flow. Improvement is to lower the back pressure.

As shown in FIGS. 7 and 8, the metal-ceramic mixed filter unit 230 has a structure in which the ceramic filter 231 and the metal filter 232 are mixed at a certain ratio, and the metal filter 232 is It is configured to surround the ceramic filter 231 from the center (FIG. 7). At this time, the ceramic filter 231 is configured at a higher ratio than the metal filter 232. For example, it can be configured in a ratio of 7:3 or 8:2.

In addition, the metal-ceramic mixed filter unit 230 has a structure in which the metal filter 232 and the ceramic filter 231 are stacked, that is, the metal-ceramic mixed filter unit 230 has the front and rear surfaces of the ceramic filter 231. , and a metal filter 232 is attached to at least one of the front and back sides (FIG. 8). At this time, the ceramic filter 231 of the metal-ceramic mixed filter unit 230 is thicker than the metal filter 232.

The metal-ceramic mixing filter unit 230 configured as described above oxidizes carbon using the gas component NO ₂ in the exhaust gas filtered in two stages through the cyclone unit 220 and prevents exhaust gas accumulation. In order to prevent an increase in the pressure of the ceramic filter 231 due to an increase in the pressure of the ceramic filter 231, the ceramic filter 231 with an internal lattice structure and the metal filter 232 formed along the flow direction of the exhaust gas are configured left and right continuously to prevent the particles of the exhaust gas from entering the deep area. It allows for positive collection and improves air flow to lower back pressure.

Therefore, in order to improve the problems of the ceramic filter, a metal-ceramic mixed filter unit 230 is formed by combining a metal filter with a rapid temperature rise and excellent ventilation effect, thereby preventing the ceramic filter from clogging due to excessive collection and operating the generator. The back pressure problem can be solved.

Additionally, the metal-ceramic mixing filter unit 230 can reduce the emission of nitrogen oxides (NOx) or particulate matter (PM) contained in the discharged exhaust gas.

By effectively removing particulate matter through the metal-ceramic mixing filter unit 230, clogging of the filter is prevented in advance, and the effect on the back pressure of the exhaust gas is minimal, thereby preventing a decrease in output or fuel efficiency.

In addition, by applying the metal-ceramic mixed filter unit 230, a smoke combustion function is possible with a rapid temperature rise, and the clogging phenomenon of the filter is alleviated, thereby ensuring stability of back pressure.

The exhaust gas particles flowing into the cyclone unit 220 pass through the cylinder unit 222 and move in a spiral motion along the cone unit 223 due to a downward external rotation flow. The dust is separated from the air stream by the centrifugal force formed and falls into the air stream. The separation force increases as the cubic size of the dust particles increases, but the resistance of the particles in the direction of the cyclone wall increases as the diameter of the particles increases. Therefore, the separation limit particle size corresponding to 50% of the weight fraction in the size distribution of the collected dust particles is calculated. The limiting particle size is as shown in Equation 1 below.

Here, D _p is the separation limit particle diameter, μg is the viscosity of the gas, Wi is the inlet width of the cyclone section, Ni is the number of vortex rotations in the cyclone section (5 to 10, usually 5), Vi is the gas inflow speed, and Pp is the discharge particle. Density, P is the density of the gas.

In addition, the efficiency of the cyclone unit 220 improves as the speed of the processing gas increases, but the input loss increases, so the pressure loss of the cyclone device can be predicted as shown in Equation 2.

Here, D _c is the outer cylinder diameter (cylinder diameter), L _c is the outer cylinder length (cylinder part length), H _c is the circumferential length (length between the filtering part and the dust collection part), and D _e is the inner barrel diameter (passage inner diameter). , a is the inlet area, V _i is the incoming gas velocity, g is the gravitational acceleration, and p is the particle density.

The operation of the monitoring system for a generator equipped with a smoke reduction device according to the present invention configured as described above will be described as follows.

As shown in FIG. 10, the monitoring system for a generator equipped with a smoke reduction device according to the present invention includes a vibration sensor that measures vibration of the emergency diesel generator, a pressure sensor that measures pressure during operation, and noise generated from the generator during operation. Measured data from the emergency diesel generator sensor system, which consists of a noise sensor that measures the temperature, one or more sensors that measure the temperature of coolant, oil, and equipment, and a sensor that determines the status of the smoke reduction device, is transmitted by wire or wirelessly. It receives information using a communication method and comprehensively determines the status of the facility.

Next, the component or structure in which an abnormality occurred is visually expressed so that the user can easily recognize it, and by helping with maintenance and inspection in advance, major accidents are prevented, and by implementing startup trends for each data, the operation status and development of the device are monitored. Efficiency, power generation, etc. can be seen at a glance, allowing the emergency diesel generator to be operated without over- or under-generation when it is needed, thereby saving fuel needed for startup.

In addition, the present invention receives measured data from each sensor wired or wirelessly and classifies each data element. For example, data elements such as temperature, gas, pressure, etc. related to the filter remaining amount and operation of the exhaust emission reduction device are judged and classified as one category.

This classification is not limited to one part per type of data, but may be classified into multiple categories simultaneously.

Once the classification of the data is completed, data on the status of the equipment associated with each data, the amount of power generated by the emergency generator, and the remaining amount of the exhaust emission reduction device are calculated and processed into data necessary for status diagnosis. The processed data is judged based on the comparison of each judgment unit, and if there is no problem, the process returns to the task of collecting data from the sensors and the operation is performed again.

In addition, if the data measuring the fuel amount and smoke reduction filter determines that the amount is below the standard value, the monitoring system notifies in the form of an alarm that there is an abnormality in the fuel quantity and the remaining amount of the smoke reduction filter and displays the color of the fuel tank and smoke reduction device in the monitoring system. It displays from green, which is operating normally, to yellow or red to notify of equipment abnormalities.

If a defective facility is detected within the emergency generator, the level of abnormality in the facility is determined. Afterwards, it is notified in the form of an alarm that there is a problem with the facility, and if the facility is operable but requires inspection, it is displayed in yellow, and if there is a risk of a critical problem occurring during the operation of the facility, it is displayed in red. Make it possible.

Meanwhile, although the present invention has been described above using several preferred examples, these examples are illustrative and not limiting. Those of ordinary skill in the technical field to which the present invention pertains will understand that various changes and modifications can be made without departing from the spirit of the present invention and the scope of rights set forth in the appended claims.
