Description

Portable carbon cleaning apparatus for automobile maintenance shop TECHNICAL FIELD

The present invention relates to a carbon cleaning apparatus for an automobile maintenance business using brown gas.

Typically, when water is electrolyzed, hydrogen is obtained from the cathode and oxygen is obtained from the anode. Brown gas is collected at once without separating these gases.

Brown gas, unlike general gases, has a unique property that causes an impulsion phenomenon during combustion. In other words, it does not show an explosion phenomenon during combustion, but rather forms a focal point as the flame gathers inside and vacuumizes the surroundings.

As a result, when brown gas is burned, it is possible to obtain an ultra-high temperature enough to sublimate even tungsten, which has the highest melting point.

In addition, since the heat ray is not emitted to the outside, there is no energy loss due to radiant heat, so it has excellent energy efficiency, and since it contains oxygen itself, separate oxygen supply is not required during combustion. In addition, since only water is produced as a combustion product, there is no pollution problem.

On the other hand, a car engine carbon removal apparatus using such brown gas has been proposed. For example, Korean Patent Application No. 10-2016-0135033 "An engine performance restoration system having a function of removing carbon from an automobile engine intake part, exhaust catalyst and engine combustion chamber using brown gas" relates to such a device.

However, there is a limitation in use of the brown gas generator used for engine carbon cleaners in such conventional automobile maintenance businesses. First, since a single-phase 220V is used, the metal electrode causes an oxidation reaction, resulting in poor durability. Despite being expensive, it can only be used for 3 to 6 months, and its lifespan is very short. Second, the problem of environmental pollution may occur due to excessive exhaust gas during engine cleaning work in a maintenance shop. Third, it is difficult to check the effect of how much carbon has been removed inside the engine after cleaning.

The present invention provides a carbon cleaning apparatus including a portable brown gas generator that is easy to be transported and applied to the field so as to be suitable for automobile maintenance businesses.

Compared to, it is enlarged.

In addition, the battery may be characterized in that it is a battery for a vehicle.

In addition, it may further include a connecting pipe connected between the intake pipe of the intake system and the automobile engine and having a separate supply path for supplying the brown gas on the path of the intake pipe.

In addition, the PWM control unit may control the voltage supplied to the brown gas generator in a range of 12V to 24V.

In addition, the Brown gas generator may include a pair of first electrode plates to which a positive voltage is applied; A second electrode plate to which a negative voltage is applied; A plurality of third electrode plates arranged between the first electrode plate and the second electrode plate; First and second plates disposed to face each of the pair of first electrode plates and having an electrolyte inlet or a gas outlet; And a sealing member disposed between the first electrode plate, the second electrode plate, and the third electrode plate and having an empty center, wherein the first electrode plate, the second electrode plate, and the third electrode plate are made of a conductive polymer material. It is an electrically conductive plastic electrode plate formed by injection molding by using, and on the surfaces of the first electrode plate, the second electrode plate, and the third electrode plate, a positive or negative pattern for vaporizing the contact area with the electrolyte, and the flow of the electrolyte. It may be characterized in that the flow hole is formed for.

In addition, the conductive polymer material may be a composite of reduced graphene oxide (RGO)/polypyrrole.

In addition, the first plate may be provided with an electrolyte inlet and the second plate may be provided with a gas outlet.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Unless there is a specific definition or reference, terms indicating directions used in this description are based on the states indicated in the drawings. In addition, the same reference numerals refer to the same members throughout each embodiment. On the other hand, each component shown in the drawings may be exaggerated in thickness or dimensions for convenience of description, and does not mean that it should be configured in a ratio between the corresponding dimensions or components.

A portable carbon cleaning apparatus according to an embodiment will be described with reference to FIG. 1. 1 is a block diagram illustrating a configuration of a carbon cleaning apparatus according to an exemplary embodiment.

The portable carbon cleaning device 10 according to the present invention includes a water circulation system including a water tank 35 and a circulation motor 30 centering on the brown gas generator 100, a PWM control unit 20, and a battery 25 It can be divided into a power supply system including, and a cleaning/monitoring system including a connection pipe part 500, a monitoring part 45, and an endoscope part 40.

In the water circulation system, water supplied from the water tank 35 is circulated using a circulation motor 30 and supplied to the brown gas generator 100, and the remaining water is recovered back to the water tank 35.

The battery 25 according to the present embodiment uses a DC power source, and for example, a vehicle battery may correspond to this. The battery may be controlled by the PWM controller 20 in proportion to the amount of brown gas generated in the range of 12 to 24V.

The brown gas generating device 100 generates brown gas using electrolysis. Brown gas generated from the brown gas generator 100 is supplied directly to the engine 5 through an intake pipe, or a separate connection pipe 500 is connected between the intake pipe and the engine 5 and then supplied through it. Can be.

Brown gas may be discharged to the outside through an exhaust pipe together with the exhaust gas after cleaning the carbon in the engine 5, or may be discharged to the outside after passing through a separate smoke reduction device.

Meanwhile, the Brown gas generator 100 according to the present embodiment uses an electrode made of a conductive plastic material as an electrode for electrolysis.

The metal electrode plate has the following disadvantages. First, there is a problem that durability is rapidly reduced by being rusted by an oxidation reaction, and for this reason, it is difficult to obtain pure brown gas. Second, titanium-plated platinum is currently used the most, but it is economically disadvantageous because it requires a relatively high cost. However, even in the case of platinum-plated titanium, it is oxidized and has poor durability. third. The amount of brown gas generated is proportional to the surface area of the electrode plate when the same power is applied. However, the metal plate has technical and economic limitations in processing to increase the surface area.

For this reason, the carbon cleaning apparatus according to the present invention implements a brown gas generator using an electrically conductive plastic electrode plate.

Such a brown gas generator has the advantage that the electrode does not rust and is inexpensive. In addition, in the case of a brown gas generator using conductive plastic, it is possible to increase the surface area economically at a low cost, and there are few technical restrictions required for processing to increase the surface area due to the good moldability of the electrode itself. In addition, since it is possible to easily increase the surface area of the electrode as described above, power required to generate the same brown gas can be minimized, and due to this difference, there is an effect of enabling a portable carbon cleaning device.

By using conductive plastic as an electrode plate, it is possible to improve processability and economic efficiency to increase the amount of brown gas generated, and through this, the amount of power required to obtain the necessary brown gas can be greatly reduced, and through this, a device for cleaning carbon from automobile engines. It became possible to manufacture in a portable type. That is, the carbon cleaning apparatus according to an embodiment of the present invention can perform engine carbon cleaning while operating the vehicle by consuming low DC electricity of the vehicle by connecting it to a vehicle battery. Due to this feature, since there is no need to remove carbon through idling in automobile manufacturers, etc., there is no fear of causing damage to residents by generating pollution, and there is an effect that carbon can be removed through daily operation.

In addition, it is possible to check whether the proper cleaning work is performed by installing the engine endoscope and checking the engine condition before and after the work with the endoscope.

The electrode using the conductive plastic stick of the brown gas generator is pounded and then the shape is stamped out by injection using a binder. The surface area can be remarkably increased by embossing the perforation or surface during mold work, so it has good workability compared to the brown gas generator using a metal electrode, and can significantly increase the amount of brown gas generated.

At this time, for example, a method of increasing the amount of brown gas generated by increasing the surface area of the electrode by using a cell size of a fixed value (10*10cm) and using 10 + poles-10 poles, and a PWM control method. A method of preventing overcurrent and overvoltage by fixing voltage (5v~12v) and current (15~20A) during electrolysis can be applied by applying.

The endoscope part 40 is inserted so that the inside of the engine can be observed through the connection pipe part 500 or the intake pipe. The image captured through the endoscope unit 40 can be checked by the monitoring unit 45. It is possible to directly check the intake air cleaning effect through the endoscope unit 40.

When the endoscope unit 40 is inserted directly into the intake pipe, a method of inserting a hole in the intake pipe and sealing it again after confirmation may be used. At this time, you can remove the spark plug and check the inside of the engine block. Through this process, it is possible to check the working status of carbon cleaning in a simple way.

Referring to FIG. 2, the connection pipe part 500 includes a second end 530 and a brown gas that separates the intake pipe from the engine side and then reconnects the connected first end 510 and the separated intake pipe. It may include a third end 520 into which is injected and the endoscope is inserted. The third end 520 communicates with a flow path connecting the first end 510 and the second end 530 so that brown gas and intake air can be mixed. That is, the connection pipe part 500 forms a separate supply path for supplying brown gas on the path of the intake pipe.

In the present specification, for convenience of description, the first electrode plate 110 and 120 is a positive electrode and the second electrode plate 130 is a negative electrode.

As in the present embodiment, when the second electrode plate 130, which is a negative electrode, is disposed between the first electrode plates 110 and 120, which are positive electrodes (it is also possible when the first electrode plate is a cathode and the second electrode plate is an anode), By minimizing the size or number of electrode plates, there is an advantage in that electricity consumption can be drastically reduced to produce brown gas. In addition, in the third electrode plate 140 between the first electrode plate 110. 120 and the second electrode plate 130, electrons move according to the polarity of the adjacent electrode plate, thereby generating a greater amount of brown gas. Provides the advantage that there is,

The sealing member 170 may have a rim surface coincident with the electrode plates and a central portion thereof may be empty. The sealing member 170 blocks the edge space between the electrode plates, that is, the first electrode plate 110. 120, the second electrode plate 130, and the third electrode plate 140, thereby securing airtightness inside the device. In this way, a space for filling the electrolyte solution may be formed. In addition, the sealing member 170 may be a spacer maintaining a gap between the first electrode plate 110 and 120, the second electrode plate 130, and the third electrode plate 140.

In particular, the third electrode plate 140 has a plate shape whose thickness increases toward one side. For example, as shown in (b) of FIG. 6, the thickness may be increased from the bottom to the top. This configuration is effective in removing air bubbles that may adhere to the surface of the electrode plate and impair the electrolysis efficiency. In other words, since the electrolyte from the electrolyte inlet 162 (refer to FIG. 3) can be introduced along the inclined surface of the electrode plate, air bubbles attached to the surface of the electrode plate can be swept away, thus increasing the electrolysis efficiency. There will be.

The embossed or engraved pattern 142 may be formed in various shapes.

As another example, the flow holes 144 of the first to third electrode plates are alternately formed in a vertical direction or a horizontal direction. Referring to FIG. 9, one flow hole 144 of the third electrode plate 140 may be formed in a vertical direction, while the remaining flow holes 144 may be formed in a vertical direction. Here, the vertical direction is defined as a direction parallel to the first and second plates 150 and 160 for convenience, and the horizontal direction is defined as a direction orthogonal to the first and second plates 150 and 160.

In this embodiment, the first plate 150 may be provided with an electrolyte inlet 162 and the second plate 160 may be provided with a gas outlet 164.

In contrast, as shown in FIG. 10, both of the electrolyte inlet 162 and the gas outlet 164 may be provided in any one of the first and second plates 150 and 160, that is, the second plate 160. I can.
