The gas that has passed through the flow meter PG-1 flows into the engine room through the piping connected to the gas discharge end 16.

Meanwhile, a hydrogen sensor 120 is installed in the main body 10, and when gas is leaked into the main body, the hydrogen sensor 120 detects gas leakage, and the control module 20 immediately stops the operation of the apparatus I can warn you.

The description of the brown gas generator 1 according to the embodiment of the present invention will be made more clearly from the following description of the operating state. In addition, the operation of the Brown gas generator will be described with reference to the flow chart shown in Fig.

1 to 4, the vehicle battery 31 is connected to the terminal 14 on the rear surface of the main body 10 while the signal input terminal 15 is connected to the ECU 32, And the gas discharged through the flow meter PG-1 and discharged to the gas discharge end 16 is connected to the engine room of the vehicle through the final pipe 110. [

Before using the Brownian gas generator 1, the user opens the inlet port 42 to fill the inside of the auxiliary tank 40 with a proper level of water through the inlet port 41. The first level sensor LS-1 transmits a water shortage signal to the control module 20 when the power is supplied and the display 26 of the controller 23 is connected to the first water level sensor LS- (Warning sound or warning lamp) is outputted through the auxiliary water tank 40 that the water in the auxiliary water tank 40 is insufficient.

When the user turns on the power switch 11 to operate the brown gas generator 1, the control module 20 performs the self-diagnosis first according to the preprogrammed program and then outputs the state of the system through the display 26 do.

The controller 23 is provided with various sensors such as a first level sensor LS-1, a second level sensor LS-2, a first temperature sensor TE-1, a second temperature sensor TE- And a pressure sensor PS-1, respectively, and can display states in different colors.

In this case, when the water level of the auxiliary tank 40 is higher than the reference level through the signal measured by the first water level sensor LS-1 as a result of the self-diagnosis of the control module 20, green is lighted on the first lamp, . Further, when the water level of the main water tank 50 is higher than the reference value through the signal measured by the second water level sensor LS-2, the green lamp is turned on the second lamp, and the red color is turned on. When the temperature of the water in the main water tank 50 is higher than the reference temperature (for example, 45 degrees or more) through the signal measured by the first temperature sensor TE-1, the red lamp is lit in the third lamp, . When the temperature inside the main body 10 is higher than the reference temperature (for example, 60 degrees or more) through the signal measured by the second temperature sensor TE-2, the red lamp is turned on for the fourth lamp, have. If there is an excessive pressure rise in the pipe 110 through the signal measured by the pressure sensor PS-1, the red lamp may be turned on the lamp No. 5 and the green lamp may be turned on.

When the signals of all the sensors LS-1, LS-2, TE-1, TE-2, PS-1 and PG-1 are normal as a result of the self-diagnosis of the control module 20, It is possible to inform the user that green is lighted and the operation standby state is established. On the other hand, if an error occurs in one or more sensors (LS-1, LS-2, TE-1, TE-2, PS-1, PG-1) as a result of the self-diagnosis, You can warn the user through. Of course, in this state the system does not perform the normal operation of producing brown gas by electrolyzing the water, and will notify the user that the problem can be solved through follow up.

For example, if the water in the auxiliary water tank 40 is insufficient, the water can be filled by the user. If the water in the main water tank 50 is insufficient, the solenoid valve SV-1 is opened by the control module 20 The pump PUMP-1 is operated so that water in the auxiliary tank 40 can be supplied to the main water tank 50. When the temperature of the water in the main water tank 50 is higher than the reference level (for example, 45 degrees or more), the electrolytic bath fans FAN-1 and FAN-2 are operated to lower the water temperature down to a certain level When the temperature inside the main body 10 is higher than the reference temperature (for example, 60 degrees or more), the main fan FAN-3 is operated to discharge the hot air inside the main body 10, (E.g., 55 degrees) below a certain level. The excessive pressure rise in the pipe 110 through the pressure sensor PS-1 is a state in which a part of the entire piping 110 is pushed or bent due to an external factor so that the gas can not flow smoothly. And warns that external factors can be eliminated.

The control module 20 supplies electric current to the electrode plate 68 of the electrolytic bath 60 according to the user command inputted through the operation button 25 of the controller 23 so that the water can be electrolyzed.

The electrolytic bath 60 is connected to the main water tank 50 to receive water, and the brown gas generated by electrolysis is discharged to the main water tank 50 again. The main water tank 50 and the electrolytic bath 60 will be described in more detail with reference to FIGS. 5 to 7. FIG.

6 showing the outside of the main water tank 50 and a part of FIG. 5 showing the inside of the main water tank 50. The upper part of the main water tank 50 is connected to the solenoid valve SV- And a water replenishment port 52 for receiving water from the side of the carbon removal filter 70. The gas replenishing port 52 is provided in the electrolytic tank 60 to discharge the brown gas flowing back into the main water tank 50 toward the carbon removal filter 70 And an outlet 55 is provided. A second water level sensor LS-2 for measuring the water level in the main water tank 50 and a water discharge port 53 for supplying water of the main water tank 50 to the electrolytic bath 60 side ). A gas inlet 54 through which brown gas generated in the electrolytic bath 60 flows is provided on the side surface of the main water tank 50 and a first temperature sensor TE- 1 for measuring the temperature of water in the main water tank 50 ) Are also installed. A plurality of partition walls 51 are provided in the main water tank 50 in the width direction and the height direction of the main water tank 50. This prevents water from being shuddered in the main water tank 50 as much as possible will be.

7, the electrolytic bath 60 includes a plurality of electrode plates 68. The panels 61 provided on both sides of the electrode plate 68 are coupled with the bolts 69a to form the electrode plates 68 . A water replenishment port 65 (provided on the opposite side to the direction shown in FIG. 7) is connected to the lower end of one side of the electrolytic bath 60 and connected to the water outlet 53 of the main water tank 50 by a pipe 110, And a gas discharge port 66 for delivering Brown gas generated by electrolysis in the electrolytic bath 60 to the gas inlet 54 of the main water tank 50 is provided at the center of the other upper end. A drain port 67 for draining the remaining water is provided at the lower end of the electrolytic bath 60. The electrolytic bath 60 maintains a constant temperature atmosphere through the heater 64 in accordance with the control signal of the control module 20. [

The water supplied through the water replenishment port 52 of the main water tank 50 is connected to the water replenishment port (not shown) connected to the water outlet port 53, 65 to the electrolytic bath 60. At this time, a valve is not provided in the pipe 110 connecting the water outlet 53 and the water replenishing port 65. That is, after a predetermined amount of water stored in the main water tank 50 is supplied to the electrolytic bath 60 by using the valve, the valve is closed again so that the water inside the main water tank 50 and the water inside the electrolytic bath 60 are completely separated And the water outlet port 53 of the main water tank 50 and the water replenishing port 65 of the electrolytic bath 60 are kept connected through the opened pipe 110 at all times. Since the sealed electrolytic bath 60 is located below the main water tank 50, when the electrolytic bath 60 is full of water, the water in the main water tank 50 no longer flows into the electrolytic bath 60, When water is electrolyzed in the electrolytic bath 60 and the water level is lowered, water in the main water tank 50 flows into the electrolytic bath 60 in real time.

When the water temperature is raised by electrolysis in the electrolytic bath 60 for a long time, the temperature of the water in the main water tank 50 also increases together with the electrolytic bath 60, 1 is detected by the temperature sensor TE-1, the electrolyzer tanks FAN-1 and FAN-2 are operated by the control signal of the control module 20 to perform the cooling process.

On the other hand, brown gas generated by electrolysis of water by supplying current to the electrode plate 68 of the electrolytic bath 60 may be directly supplied to the carbon removing filter 70 as it is performed. However, since the gas generated through electrolysis in the electrolytic bath 60 contains potassium hydroxide (KOH) and other impurities in addition to Brownian gas, it is preferable to reduce it again. To this end, in the present embodiment, the gas containing brown gas produced in the electrolytic bath 60 is introduced into the main water tank 50 through the gas inlet 54 connected to the gas discharge port 66. At this time, the gas inlet 54 is located at a height where water is always filled in the main water tank 50. Therefore, potassium hydroxide and impurities contained in the gas produced in the electrolytic bath 60 flow into the water in the main water tank 50 and are reduced, and only the brown gas is elevated and escapes through the gas outlet 55.

In addition, when the gas discharge port 66 of the electrolytic bath 60 is directly connected to the downstream side of the engine, there is a fear that heat is directly transferred to the electrolytic bath 60 when the high heat such as flame is backfired in the engine room. However, in this embodiment, since the gas is connected to the following configuration through the gas outlet 55 of the main water tank 50, even if backfire occurs, the high heat is firstly encountered by the water stored in the main water tank 50, ) Side is transmitted from the source of the backfire phenomenon. Of course, the high heat transmitted from the engine compartment side can be blocked by the backfire prevention device 80, which will be described before the introduction into the main water tank 50, and the connection between the main water tank 50 and the electrolytic bath 60 The structure can prevent complete backfire.

The water stored in the main water tank 50 while being maintained at a certain water level is not used solely as a function of the raw material supplied to the electrolytic bath 60 and the water contained in the gas generated in the electrolytic bath 60, The impurity reduction and backfill prevention function can be performed more smoothly as the slumping of water through the partition 51 is minimized as described above.

On the other hand, when electrolysis is continuously performed in the electrolytic cell 60 and the temperature is increased, a leakage occurs in the laminated structure of the electrode plate 68, and the gas can escape into the internal space of the main body 10 while expanding. 7, a washer 62 is installed on a bolt 69a for fixing both end panels 61 of the electrode plate 68 of the electrolytic bath 60, The panel 61 on both sides of the electrolytic bath 60 is brought into close contact with the pressing spring 63 by fixing the pressure spring 63 between the washer 61 and the nut 69b on the opposite side of the washer 62, To eliminate the concerns of leakage.

Brown gas generated by electrolysis in the electrolytic cell 60 supplied with water from the main water tank 50 flows into the water in the main water tank 50 again to reduce the impurities and the brown gas rising to the upper portion of the main water tank 50 Is introduced into the carbon removal filter (70) through the gas outlet (55).

The carbon removing filter 70 is provided to remove moisture and impurities contained in the brown gas again. The brown gas passing through the carbon removing filter 70 is supplied to the backflow preventing device 90, And is then supplied to the engine room through the gas discharge end 16 after passing through the flow meter PG-1.

The backflow prevention device 90 is provided to prevent gas from flowing backward from the engine side. Fig. 8 is a perspective view showing the backflow prevention device 90, and Fig. 9 is a sectional view showing a part of the backflow prevention device 90. Fig. 8 and 9, the backflow prevention device 90 includes a backflow preventing body 93 having a backflow preventing space 91 therein and a thin Teflon film 92 provided in the backflow preventing space 91 .

The backflow prevention space 91 is inclined so that its diameter becomes narrower toward the lower part. A radial inflow groove 94 is formed in the upper surface of the backflow prevention body 91 in the backflow preventing body 93. And the Teflon film 92 has a plate shape that is partially curled up so that its periphery faces upward.

Accordingly, as shown in FIG. 10, when the normal flow gas flows in from the downward direction of the backflow preventing body 93, the Teflon film 92 is gently pushed up. At this time, since the backflow prevention space 91 has a larger diameter toward the upper side, the Teflon membrane 92 is not limited to be pushed up, and the gas introduced through the clearance around the Teflon membrane 92 passes therethrough, 93). ≪ / RTI >

The Teflon membrane 92 is closely adhered to the inner surface of the backflow preventing body 93 corresponding to the upper portion of the backflow preventing space 91 so as to close the upper flow path, The gas can travel through the inlet groove.

On the other hand, as shown in FIG. 11, when the gas flows backward, the Teflon film 92 descends downward. Since the backflow prevention space 91 becomes narrower toward the lower side, the periphery of the Teflon membrane 92 is prevented from flowing backward And is brought into close contact with the lower circumference of the space 91. Further, since the inflow groove 94 is not formed on the lower circumferential surface of the backflow preventing space 91, unlike the upper surface, the backflow gas can no longer flow into the lower flow path of the backflow preventing body 93.

The brown gas generator 1 according to the embodiment of the present invention can be applied to an internal combustion engine of an automobile. In this case, Brown gas generated by electrolysis in the electrolytic bath 60 is only slightly higher than atmospheric pressure. Therefore, it is impossible to block the low backflow pressure in the general backflow prevention structure. Therefore, when the backflow generator 90 having the same structure as in the present embodiment is applied, the fine Teflon membrane 92 can be shut off while the reverse flow of very low pressure is generated.

A pressure sensor PS-1 is installed at the rear end of the backflow prevention device 90. Fig. 12 is a view for explaining the pressure sensor PS-1. 12, the pressure sensor PS-1 is provided with a pressure switch 121, and a piping support portion (not shown) of a steel structure which surrounds the piping 110 made of silicon 122). Therefore, when brown gas flows along the pipe 110 at normal pressure as shown in FIG. 13 (a), the pressure switch 121 of the pressure sensor PS-1 is not pressed. However, if the pressure in the piping 110 becomes high due to the carelessness of the user (by pressing the piping 110) or another cause, the silicon piping 110 is swollen and the pressure switch 121 is depressed as shown in (b) of FIG. And the contact signal is transmitted to the control module 20 accordingly. In this case, the brown gas generator 1 is brought to an emergency stop, and a warning lamp and a warning sound are generated.

A back-flow prevention device 80 is connected to the downstream end of the pressure sensor PS-1. The backfire prevention device 80 is provided to prevent high heat such as a flame from flowing backward from the engine side. Fig. 14 is a perspective view showing the backfire prevention device 80, and Fig. 15 is a cross-sectional view showing a part of the backfire prevention device 80. Fig. As shown in FIGS. 14 and 15, the backfire prevention device 80 of the present embodiment is formed with a backfire prevention space 81 having a funnel structure with a wide outlet direction. In the backfire prevention space 81, The material 82 was filled. The anti-backfill material 82 is a material such as a soft cotton pad made of copper. Therefore, at room temperature as shown in FIG. 15 (a), brown gas can flow through the fine gaps of the anti-backlash material 82 and flow toward the engine compartment. On the other hand, when high heat such as a flame is generated from the engine room side and the backfire proceeds, the backfire prevention material 82 is melted by the high heat. In other words, the backfire prevention material 82 is formed by bundling a metal such as copper in the form of a cotton, and thus is very vulnerable to heat because of its wide surface area. Therefore, when backfire occurs, the backfire prevention material 82 is instantaneously melted, so that the melt 82 'blocks the flow path as shown in FIG. 15 (b). Therefore, the high heat generated from the engine compartment side is no longer transmitted to the electrolytic bath 60 side through the backfire prevention device 80.

In order for the function of the backfire prevention device 80 to be performed more smoothly, it is sufficient that the outlet direction is directed upward. In this case, the cross-sectional shape of the backfill prevention space 81 becomes an inverted triangle. Accordingly, when the backflushing material 82 is melted due to backfire, the melt 82 'flows along the hypotenuse of the inverted triangle shape to block the flow path in the inlet direction. In addition, the backfill prevention space 81 is formed in the form of a funnel so as to allow the melt 82 'to flow downward, and at the same time, to input as much bulk backfire prevention material 82 as possible .

If the flow path of the backfire prevention device 80 is blocked as shown in FIG. 15 (b), the brown gas can no longer be transmitted to the engine room side. In this case, the pipe 110 passing through the pressure sensor PS- So that the control module 20 can warn the user through the display 26. When the backfire prevention device 80 is damaged by backfire, the user only needs to replace the backfire prevention device 80, and there is no abnormality in the other configurations, so that the entire system can be used again at low repair cost.

The brown gas that has normally passed through the backflow prevention device 90, the pressure sensor PS-1 and the backfire prevention device 80 passes through the flowmeter PG-1 and then exits through the gas discharge end 16 and flows into the engine room . The flowmeter PG-1 is for checking the amount of gas flowing through the pipe 110 and the flow rate sensed by the flowmeter PG-1 is displayed on the flowmeter 100 and can be confirmed by the user.

16 shows a state in which the main board lid 22 and the switch board lid 24a are removed from the brown gas generator 1 shown in Fig. 1 and the main board 21 and the switch board 24 are exposed will be. The main board 21 constituting the control module 20 and the switch board 24 included in the controller 23. As shown in FIG. As shown in FIG. 16, even if the boards 21 and 24 are fixed to the front surface of the main body 10, there is no problem in using them. However, if gas is leaked while the boards 21 and 24 are exposed in the internal space of the main body 10, if there is a small static electricity or spark on the main board 21 or the switch board 24, there is a fear of fire or explosion Can be. Therefore, if the main board 21 and the switch board 24 are sealed with the main board lid 22 and the switch board lid 24a and the periphery is completely sealed with silicon as shown in FIG. 3, It is possible to eliminate the risk of explosion.

On the other hand, the signal input terminal 15 connected to the control module 20 is provided for producing brown gas with optimum efficiency according to the vehicle condition. That is, the engine RPM of the vehicle, the running speed (low speed, medium speed, high speed), and the like, and adjusts the current supplied to the electrolytic bath 60 to control the production amount of the gas. Therefore, it is possible to increase the power consumption efficiency of the Brown gas generator (1) and produce the optimum gas. Of course, when applied to general industrial fields other than vehicles, it is natural that power efficiency can be improved by controlling the gas production amount by receiving signals of various systems through the signal input terminal 15.

In the above description, the power switch 11 provided at the upper rear of the main body 10 is operated to turn on or off the entire system. However, when the control module 20 executes the signal input terminal 15 The power source may be automatically turned on or off according to an external signal input through the power source. For example, when the vehicle is started, the control module 20 turns on the device, and when the startup is turned off, the power of the device is automatically turned off.

As described above in detail, according to the brown gas generator 1 of the present invention, brown gas is supplied to an internal combustion engine of an automobile to reduce harmful components contained in exhaust gas and improve fuel efficiency.

In particular, when high heat is generated in the engine side and the gas flows backward, the copper material of the backfire prevention device 80 melts and blocks the flow path, thereby completely preventing backfire.

Brown gas produced in the electrolytic bath 60 may be directly supplied to the water stored in the main water tank 50 to reduce sodium hydroxide (KOH) or impurities. At this time, since the partition wall 51 is provided in the main water tank 50 to minimize the water swirling, it is possible to prevent the gas flowing into the electrolytic bath 60 from flowing into the water free portion.

In addition, the Teflon film 92 of the backflow prevention device 90 can completely shut off the back flow of gas at the engine side in response to the fine backflow pressure.

When the pressure in the silicon pipe 110 becomes high and the silicone pipe 110 expands, the pressure switch 121 of the pressure sensor PS-1 is immediately pressed to warn the user and the two panels 61 of the electrolytic bath 60 So that water or gas can be prevented from leaking.

That is, the Brown gas generator (1) according to the present invention is designed to ensure safety and performance by being optimized for an internal combustion engine of an automobile. As a matter of course, it is also possible to use it in a general industrial field where brown gas is required.

17 is a perspective view for explaining a Brown gas generator 1 according to another embodiment of the present invention. That is, the brown gas generator 1 'according to FIG. 17 facilitates the replacement work by mounting the carbon removal filter 70', which is required to be replaced after a certain amount of use, outside the main body 10 ' The controller 23 'including the board is manufactured in a portable form instead of being integrally formed with the main body 10'. The controller 23 ', which is manufactured in the portable form, can exchange signals with the main body 10' via a cable, but may also transmit data through a radio signal. Therefore, according to the Brownian gas generator 1 'shown in FIG. 17, the controller 23' is provided near the driver's seat so that the user can easily input an operation command or confirm the state of the apparatus.

Fig. 18 shows another example of a controller applied to the Brown gas generator. The controller 23 '' shown in FIG. 18 includes an operation button 25 '', a knob 25a, a display 26 '', and a power switch 29 ''.

In other words, in the brown gas generator 1 shown in FIG. 1, the main body 10 is provided with the power switch 11 to turn on / off the power of the entire system. ) Up to the power switch 29 ".

In addition, since the controllers 23 and 23 'of the brown gas generators 1 and 1' shown in FIGS. 1 and 17 are capable of adjusting the brown gas generation level by using the operation buttons 25, The level of the brown gas generation can be finely adjusted through the knob 25a in the controller 23 '' shown in FIG. 18, and the current corresponding to the fine adjustment can be adjusted by the electrolytic bath So that the user's intention can be reflected more accurately.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And additions should be considered as falling within the scope of the claims of the present invention.
