In addition, looking at the characteristics of the fire department's diesel car operation, firefighters complain of pain mainly due to the exhaust gas from emergency inspections (fire vehicles, various communication equipment, etc.) in the morning, especially in the morning, starting in a cold state. Due to the nature of combustion, white smoke is generated at the initial stage of hanging, and blue smoke is generated when time elapses. Since the gas is mainly composed of aldehyde, it is acting as a risk factor to the human body due to a feeling of sore eyes and gastrointestinal gastrointestinal sensation. When completely burned, NOx and black smoke are generated, which causes not only the human body but also air pollution. As it turns into a weighting material, it generates fine dust.

As we have seen before, the exhaust gas of firefighting vehicles using diesel contains a lot of harmful factors to the human body, and these residual gases are circulating in the garage, so that the breathing apparatus of firefighters who spend most of their time indoors Inhalation causes health hazards.

Therefore, in order to discharge the residual gas in the garage of the fire station to the outside, the shutters and windows of the garage are opened to discharge it with a ventilator, but the emission efficiency of the residual gas is low, so the residual gas in the garage of the fire department is discharged to the outside. An additional exhaust gas discharge device will be installed.

However, the conventional exhaust gas discharge device does not effectively discharge, thereby generating external air pollution, and it is inconvenient to mount and remove from the exhaust port of the firefighting vehicle, resulting in vehicle damage.

Is a cross-sectional view of a dust collecting filter in, FIG. 5 is a cross-sectional view showing an interior of a duct housing according to an embodiment of the present invention, and FIG. 6 is a configuration diagram of a control means according to an embodiment of the present invention.

First, all of the fire fighting vehicles 10 are diesel vehicles, which are worn in the garage 1 and idle for a certain period of time even after the initial start-up and fire fighting activities, and in the present invention, the exhaust gas generated at this time is reduced to environmental pollution and for more smooth discharge. It is an exhaust system.

Therefore, the smart exhaust system that controls the exhaust gas of the firefighting vehicle is largely connected to the grabber (100) and the grabber (100), which is mounted on the exhaust port 20 of the firefighting vehicle 10, as shown in FIG. It may be composed of a discharge hose 200 that is installed to substantially discharge exhaust gas, and a duct housing 300 that is installed at an end side of the discharge hose 200 to control the discharge of exhaust gas.

The exhaust port 20 of the firefighting vehicle 10 discharges exhaust gas according to the operation of the vehicle, and is connected to the outlet of the engine (not shown) of the firefighting vehicle 10 to distribute the exhaust gas discharged from the engine. Let it. Although not shown, it is connected to the engine inlet and an intake port for supplying air to the engine is installed. In the case of a general vehicle, the exhaust port is located at the rear, but is formed on the side of the vehicle in preparation for flooding with a special vehicle such as the firefighting vehicle 10. I can.

The exhaust port 20 is opened as in FIG. 2A, and an exhaust port flange 30 is enclosed along the circumferential direction at the opened end.

The exhaust port flange 30 may be manufactured separately from the mold or installed by welding, etc., and may be formed of an exhaust port inclined surface 32 inclined toward the front center and an exhaust port plane 34 integrally connected from the exhaust port inclined surface 32.

On the other hand, the grabber 100 that is detached and mounted on the exhaust port 20 is made of a metal material that is not deformed in heat, and has an opening 110, but an opening inclined surface 120 may be formed inward.

The opening inclined surface 120 has the same inclined surface and depth so as to correspond to the exhaust port inclined surface 32 in a shape whose width is narrowed toward the center thereof to enable mating.

In addition, a mesh net 130 may be installed in the inner direction of the opening inclined surface 120 to primarily block contaminants.

In addition, a grabber flange 140 may be installed outside the opening inclined surface 120 along the circumferential direction.

The grabber flange 140 is a portion that is in surface contact with the exhaust port plane 34, and is preferably made of the same metal material as the exhaust port flange 30, and a predetermined space may be formed therein.

Here, the grabber flange 140 may be provided with a detachable/mounting means for attaching and detaching from the exhaust port 20.

As a detachable and mounting means, at least one insertion groove 142 is formed along the opening inclined surface 120, and a spring 144 is embedded in each insertion groove 142, and it is supported by the spring 144 to allow linear movement A compression bulge 146 may be installed so as to be.

The opening diameter of the insertion groove 142 is formed smaller than the diameter of the compression ball 146, so that at least 1/3 of the compression ball 146 is protruding.

And in response to the compression ball 146, a semi-circular groove 36 is formed in the exhaust port inclined surface 32, and when the grabber 100 and the exhaust port 20 are combined, the compression ball 146 is located in the semi-circular groove 36 Can be done.

In addition, in the inside of the grabber flange 140, the magnetic 148 is installed along the circumferential direction, so that when the grabber 10 is mounted on the exhaust port 20, the magnetic 148 may be closely fixed to the exhaust port plane 34. .

The discharge hose 200 shown in FIG. 3 is a pipe member that guides the exhaust gas of the firefighting vehicle 10 to be transferred from the garage 1 to the outside, and the material may be made of a synthetic resin material or a metal material, but it is deformed at high temperature. A metal material that does not occur may be preferred.

Furthermore, it can have elasticity by having a corrugated pipe shape.

The discharge hose 200 is again installed to be movable along the rail 2 installed on the ceiling, as shown in FIG. 1, and the rail 2 is a widely used technology and a separate description will be omitted.

As shown here, although one discharge hose 200 is shown on the rail 2, a plurality of rails 2 may be installed, and the discharge hose 200 is installed on each rail 2, Each discharge hose 200 may be installed to be branched from the main hose (not shown).

In addition, the discharge hose 200 includes a dust collecting filter 210 that catches the soot contained in the exhaust gas, for example, a warm-up catalyst (220 WCC: Warm) installed at the rear end of the dust collecting filter 210 to preheat the exhaust gas. -Up Catalyst) may be further included.

The dust collecting filter 210 will be described again with reference to FIGS. 3 and 4.

The exhaust gas discharged from the engine enters the gasoline dust collecting filter 210 through the discharge hose 200, and the dust collecting filter 210 filters the exhaust gas. Thereafter, the filtered exhaust gas is discharged through the discharge hose 200 connected to the rear end of the dust collecting filter 210.

The dust collecting filter 210 and the warm-up catalyst 220 may be connected to the control means 330 to control the operation of the exhaust gas system.

The dust collecting filter 210 may be one of a Hepa filter or a pellet filter.

The HEPA filter uses H13 class HEPA filter fabric that removes more than 99.95% of fine particles of 0.2 to 0.4 μm in size, and can remove not only yellow dust and fine dust, but also harmful substances in the air. It is something you can have.

In addition, the pellet filter may have porous pellets 214 installed inside the filter body 212 and the filter body 212.

The filter body 212 is formed with an inlet 212a through which gas is introduced in the form of a tube, and an outlet 212b is formed in a straight line in a longitudinal direction to communicate, and a pipe between the inlet 212a and the outlet 212b It can be formed to enlarge.

Through the expansion of the pipe from the inlet 212a, the flow rate can be made rapidly according to the Bernoulli principle.

In addition, between the inlet 212a and the outlet 212b, a plurality of porous pellets 214 are installed along the longitudinal direction, and the plurality of porous pellets 214 are porous spherical ceramics, and a catalyst is coated inside and outside the porous pellets. .

Here, ceramics are particularly heat resistant and are therefore suitable as pellets, and the catalyst consists of at least one material selected from platinum and rhodium. The porous pellet 214 is coated with one or more materials selected from platinum and rhodium. That is, noble metals such as platinum and rhodium are mixed with a washcoat, applied to the porous pellet 214, and then subjected to a sintering process. The catalyst performance is influenced by the loading ratio of the precious metal, the loading amount, and the quality of the washcoat. Accordingly, the NO component contained in the exhaust gas passing through the inside and outside of the porous pellet 214 can be easily oxidized to the NO2 component. As shown in the cross-sectional view of FIG. 4, while the exhaust gas passes through the porous pellet 214 in which pores are connected to each other by an open channel along the flow direction, particulate matter contained in the exhaust gas is It also comes into contact with the inside.

In this way, the NO component in the exhaust gas penetrating into the porous pellet 214 can be easily oxidized to the NO2 component. And since the porosity can be up to 80%, it takes considerably less back pressure than ceramic beads of the same size with 0% porosity.

Further, the soot accumulated in the dust collecting filter 210 is oxidized by nitrogen dioxide (NO2), and the nitrogen monoxide (NO) generated in the dust collecting filter 210 may be purified by the warm-up catalyst 220.

The nitrogen monoxide discharged from the engine is oxidized to nitrogen dioxide, and the oxidized nitrogen dioxide burns the soot accumulated in the dust collection filter 210, and the nitrogen monoxide generated in this combustion process is a warm-up catalyst 220 located at the rear end of the dust collection filter 210. ) Can be reduced.

As described above, according to the present invention, the dust collecting filter 210 is directly mounted on the discharge hose 200 close to the exhaust port 20 to maintain the exhaust gas at a high temperature, so that soot can be easily burned.

The duct housing 300 shown in FIG. 5 is connected from the discharge hose 200 and installed outside the garage 1 to control and discharge pollutants contained in the exhaust gas.

The duct housing 300 largely includes a housing body 310, an integrated sensor 320 installed in the housing body 310, and a control means 330.

The housing body 310 is made in the shape of a rectangular enclosure, and the shape is not particularly limited here.

A certain space is provided inside, an inlet part 312 connected to an end side of the discharge hose 200 and extending inward is provided, and a discharge part 313 through which exhaust gas is discharged is provided on the other side, A blower 314 for sucking exhaust gas may be installed in the inlet 312.

In addition, an integrated sensor 320 for sensing the carbon dioxide content and temperature of the exhaust gas and transmitting a signal may be installed in proximity to the inlet 312.

The integrated sensor 320 senses various physical quantities of gas flowing through the discharge hose 200 and transmits the result to the control means 330. At this time, the physical quantity of the gas varies, and means, for example, pressure, flow rate, and flow rate of the gas.

The integrated sensor 320 includes a carbon dioxide measuring module 321 that measures the carbon dioxide content contained in exhaust gas, a temperature sensing module 322 that detects the temperature of the gas, and a flow rate sensing module 324 that detects the flow rate of the gas. ), and a flow rate detection module 326 for detecting the flow rate of the gas.

The integrated sensor 320 may operate only the carbon dioxide measurement module 321 and the temperature detection module 322, or only the flow rate detection module 324 or the flow detection module 326, and the temperature detection module 322, The flow rate detection module 326 may operate together.

In this embodiment, when the initial exhaust gas is inhaled, the carbon dioxide measuring module 321 and the temperature sensing module 322 operate to detect the carbon dioxide content and gas temperature, and after being ignited, the flow rate or flow rate sensing modules 324 and 326 By this operation, it is possible to determine the state of the exhaust gas by sensing the flow rate or flow rate of the gas.

As the carbon dioxide measuring module 321, carbon dioxide non-dispersive infrared rays and carbon dioxide infrared rays may be used, but preferably, non-dispersive infrared rays having excellent precision may be used.

The non-dispersive infrared ray has a method of obtaining the concentration of a specific component by using gaseous substances such as carbon dioxide or carbon monoxide having a specific absorption spectrum for infrared rays.

In addition, the flow rate detection module 324 measures a velocity when a fluid flows through a pipeline, and various methods such as ultrasonic type, thermal type, Karman vortex type, and turbine type can be applied.

And, the flow rate detection module 326 is a module for detecting the flow rate of the gas, it is possible to operate such as a movable vane method.

These flow rate and flow rate detection modules 324 and 326 detect in real time the flow rate and flow state of the gas flowing through the inside of the exhaust gas when the gas is constantly supplied and maintained after the exhaust gas is initially introduced. The resultant value is transmitted to the control means 330. The control means 330 compares the measured value input from the integrated sensors 320 with the set value and controls the operation of the blower 314 when the value is higher than the preset value. .

In addition, in the control means 330, as shown in FIG. 6, the gas physical quantity value and the measured temperature value transmitted from the integrated sensor 320 are inputted by the input unit 332 and the value input by the input unit 332. It includes an operation unit 334 that calculates the degree of contamination, and an output unit 336 that determines whether the blower 314 operates with the motor and controls the rotational speed of the blower 314 according to the result calculated by the operation unit 334. I can.

Moreover, the control means 330 includes sequence control (eg, heat-up, operation mode, cool-down, etc.), feedback control (eg, flow control, temperature control, pressure control, etc.), EBOP control (eg, power control, etc.). , Stack status information (material transfer resistance, etc.) control), can change operating variables through real-time monitoring during operation, and can perform status control and predictive diagnosis.

The control means 330 may be connected to an upper control system through an external communication network (eg, Ethernet). The upper control system is connected to the controllers of a plurality of fuel cell systems, and is in charge of integrated control for parallel operation for each unit module (6/24/120kW) and for adjusting the load sharing in case of unit module failure.

Stability and reliability of the entire system may be improved based on the state monitoring of the control means 330 and the upper control system. It is also possible to prioritize the desired item among the lifespan and power generation output of the stack module. By replacing the unit module, the continuity of operation of the system is ensured. For example, various methods such as individual independent operation, integrated parallel operation, and load variable operation may be supported.

The control means 330 may directly/indirectly control a smart exhaust system that controls exhaust gas of a firefighting vehicle to implement an operation/step/process according to an embodiment of the present invention. In addition, the control means 330 may include at least one processor, and the processor may include at least one central processing unit (CPU) and/or at least one graphic processing device (GPU).

The control means 330 may monitor and analyze the state of the fuel cell during operation, and may adjust operation parameters according to the analysis result. Through this, the control means 330 prevents a trip and improves reliability. In addition, the control means 330 may perform rapid cause analysis and action when a trip or system stops, and accordingly, the operation rate will increase. For example, principal component analysis may include monitoring/diagnosing conditions by dualizing operation and control variables.

Control means 330, for example, based on the residual power of the fuel cell, carbon dioxide measurement module 321, temperature detection module 322, flow rate detection module 324, and some of the flow rate detection module 326 It can be controlled to operate only the module. For example, when the residual power exceeds the first threshold, a command for controlling all of the carbon dioxide measurement module 321, the temperature detection module 322, the flow rate detection module 324, and the flow detection module 326 to operate. Can be created.

As another example, when the residual power is less than or equal to the first threshold and exceeds the second threshold, one of the carbon dioxide measurement module 321, the temperature detection module 322, the flow rate detection module 324, and the flow rate detection module 326 You can create a command that controls only one to operate.

As another example, when the residual power is less than the second threshold, the carbon dioxide measurement module 321, the temperature detection module 322, the flow rate detection module 324, and the flow detection module 326 are all controlled to stop operation. You can create a command to do.

In another example, the residual power is less than the first threshold and exceeds the second threshold, and the carbon dioxide measurement module 321, the temperature detection module 322, the flow rate detection module 324, and the flow rate detection module 326 When the change amount of the value obtained by the change falls within a predetermined range, the remaining modules except for the module corresponding to the change amount within a predetermined range (that is, the carbon dioxide measurement module 321 in which the change amount is out of a predetermined range, a temperature sensing module) (322), the flow rate detection module 324, and at least one of the flow rate detection module 326) can generate a command to control to operate only. This is to reduce power waste by removing power consumption of a module that unnecessarily consumes power in order to measure a value with little change.

In addition, AI (artificial intelligent)-RNN (recurrent neural network)-based diagnosis may be performed, and accordingly, a reference value reset according to a normal state change until the end of life and precise diagnosis during trip are possible. RNN-based diagnosis can be performed based on real-time data. The intelligent controller can use the RNN to determine the normal state during operation and for precise diagnosis when stopped. The RNN can be trained or learned with data obtained from other external fuel cell systems. To this end, the control means 330 may include, for example, a machine learning unit, and the learning performed in the machine learning unit is supervised learning or unsupervised learning. It can be done by In addition, the machine learning unit learns artificial intelligence by using big data stored in the database of the control means 330 as an input variable. Specifically, an accurate correlation is established using a deep learning technique, a field of machine learning. Perform learning so that it can be derived. In particular, in the case of the above-described correlation, the input is obtained by at least one of the carbon dioxide measurement module 321, the temperature detection module 322, the flow rate detection module 324, and the flow detection module 326. Information (or value), and output may be defined as a preset threshold value. Also, eventually, the machine learning unit may calculate weights of a plurality of inputs in the function through learning through deep learning. In addition, various models, such as a recurrent neural network (RNN), a deep neural network (DNN), and a dynamic recurrent neural network (DRNN), may be used as an artificial intelligence network model used for such learning.

The operation of the smart exhaust system for controlling the exhaust gas of a firefighting vehicle according to the present invention having the above configuration will be described with reference to FIGS. 1 to 5 again.

First, after the initial start-up and firefighting activities, when the firefighting vehicle 10 is put into the garage 1 and driving is required, the user may connect the discharge hose 200 from the rail 2 to the exhaust port 20 of the firefighting vehicle 10. ) After moving to the proximity position, it is coupled to the exhaust port 20 by holding the grabber 100.

At this time, the compression ball 146 partially protruding from the insertion groove 142 of the grabber flange 140 moves in sequence while compressing the spring into the insertion groove 142 along the inclined surface 32 into which the compression ball 146 enters, and then the exhaust port flange ( When the entry of the exhaust port inclined surface 32 of 30) is completed, the compressed ball 146 protrudes and is positioned as much as the depth of the semicircular groove 36 at a corresponding position to increase the fixing force.

Moreover, it is attached to the exhaust port plane 34 by the magnetic 148 of the grabber flange 140 to further increase the fixing force.

In the above-described state, when the fire vehicle 10 is dispatched in an emergency, if it starts without a separate operation of canceling the grabber 100, it can be naturally canceled by force.

On the other hand, exhaust gas is discharged in a state in which the grabber 100 is coupled to the exhaust port 20, and contaminants of large particles are caught by the mesh network 130 of the grabber 100, and then a dust collecting filter ( While passing through the porous filter 214 of 210), particulate matter contained in the exhaust gas does not pass.

Further, the soot accumulated in the dust collecting filter 210 is oxidized by nitrogen dioxide (NO2), and the nitrogen monoxide (NO) generated in the dust collecting filter 210 may be purified by the warm-up catalyst 220.

The exhaust gas purified as described above moves along the discharge hose 200 again by the suction action of the blower 314, and then flows into the housing body 310, and the introduced exhaust gas is the carbon dioxide measurement module 321 The and temperature detection module 322 operates to detect the carbon dioxide content and gas temperature, and after being ignited, the flow rate or flow rate detection modules 324 and 326 operate to detect the flow rate or flow rate of the gas to detect the state of the exhaust gas. It is identified and transmitted to the control means 330.

Accordingly, the control means 330 compares the measured value input from the integrated sensors 320 with the set value, and controls the operation of the blower 314 when the value is higher than the preset value.

That is, when the measured value is greater than or equal to the set value, since it causes a serious level of air pollution, the operation of the blower 314 is stopped, and the start of the fire fighting vehicle 10 is turned off to find the cause.

And if the measured value input from the integrated sensors 320 is much lower than the actual value, the blower 314 is operated at a normal speed, and when it is close to the preset value, the rotational speed of the blower 314 is adjusted, and the dust collecting filter 210 ) And the warm-up catalyst 220 to extend the purification time to adjust the rotational speed of the blower 314 until it approaches a preset value.

Due to the functions as described above, the exhaust gas discharge operation is smooth by the control operation of the control system, and the health of firefighters can be kept by minimizing pollution of the garage.

In addition, since it is easy to attach and detach the exhaust port of the fire vehicle and the exhaust hose, it may be suitable for a fire vehicle requiring urgent dispatch.

Although specific embodiments have been described in the detailed description of the present invention, various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention is limited to the described embodiments and should not be determined, and should be determined by the scope of the claims and equivalents as well as the scope of the claims to be described later.
