Description

Technical Field [0001] The present invention relates to a device for reducing exhaust gas of a diesel engine through fuel activation,

The present invention relates to an exhaust gas abatement apparatus applicable to a medium or large diesel engine (about 3,000 horsepower class), and more specifically, the apparatus is arranged between a fuel tank and an engine to atomize diesel oil particles used as fuel , An exhaust gas reduction device designed to increase fuel efficiency, reduce fuel consumption, and significantly reduce air pollutants (PM (Particle Material), etc.) discharged during incomplete combustion because the fuel is completely burned in the engine .

Generally, a fuel cutter for a vehicle activates particles of gasoline or diesel oil used as a fuel so that when the fuel is injected into the combustion chamber of an engine, it is mixed with oxygen in the air to be completely combusted, thereby improving efficiency and reducing fuel consumption .

Conventional exhaust gas abatement apparatuses have been widely used in a post-treatment system for collecting and re-combusting soot and discharging it again into the air. A DPF (Diesel Particulate Filter) method is often used as the post-treatment method. However, the processing apparatus according to the conventional method is a system in which a fuel is combusted in a diesel engine to artificially collect the exhausted material, and then discharged through a re-burner to reduce the size of the particles, The fuel consumption is large and the output of the engine is lowered.

In addition, the DPF, which has been invented in the past, is a technology that can be used only in an engine having an engine capacity of less than 500 horsepower, and has a limitation in applying such technology to a medium or large-sized diesel engine.

To solve such a problem, Japanese Patent Application Laid-Open No. 10-0827430 discloses a fuel saving device for a vehicle in which a fuel atomization process can be performed.

1, the conventional fuel cutter includes a cylindrical housing 6 having an inlet port 2 and an outlet port 4 formed at both ends thereof and having first and second chambers 16 and 18 on an inner diameter side thereof. A plurality of fuel induction pipes 8 provided inside the second chamber 18 in a state that they are formed with different diameter and are coaxially fitted to each other, .

The first chamber 16 is provided with a pair of crushing holes 22 formed with spiral grooves 20 on the outer circumferential surface thereof and an orifice 24 disposed between the crushing holes 22, 8 have a plurality of connecting grooves 12 and 14 formed on the outer circumferential surface thereof and intersecting with the guide groove 10 in the longitudinal direction of the fuel induction pipe 8 to form a discharge hole 26 through which the fuel flows .

However, in the conventional fuel saving device as described above, the first and second chambers 16 and 18 provided in the housing are connected to each other through a screw connection, so that high pressure acts on the first and second chambers 16 and 18, The reliability of the product deteriorates and the crushing port 16 and the fuel induction pipe 18 provided inside the first and second chambers 16 and 18 are exposed to the outside by the operation of rotating the housing, And the orifice 24 is inserted between the crushing openings 22, so that it is difficult to realize accurate crushing effect.

Korean Registered Patent No. 10-0827430 (Published on May 05, 2008)

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is an external perspective view showing an exhaust gas reducing apparatus according to the present invention, and FIG. 3 is a cross-sectional view cut along the line I-I 'of FIG.

2 and 3, the exhaust gas abatement apparatus 50 according to the present invention includes a housing 100 forming an outer surface, diesel oil installed at one side of the housing 100, An inlet port 200 which is a passage for introducing fuel into the housing 100 and an outlet port which is provided at the other side of the housing 100 and is a passage for moving the fuel introduced into the housing 100 to the engine, 300).

A plurality of holes for mounting a plurality of components are installed in the housing 100. A ceramic block mounting hole 170 in which a ceramic block 171 is disposed inside the housing 100 with respect to a longitudinal direction of the inlet port 200 from the outlet port 300, A crushing hole mounting hole 150 in which the crushing ports 158 and 159 are disposed and a fuel induction pipe mounting hole 130 in which a plurality of fuel inducing pipes 135 are disposed are formed. A reverse flow prevention line 110 is provided at a lower portion of the plurality of holes 130, 150, and 170 to prevent backflow of fuel that has passed through the fuel induction pipe 135 in the longitudinal direction.

Generally, the fuel that has passed through the fuel induction pipe 135 moves along the exhaust port 300 and is injected into the combustion chamber of the engine. However, if the fuel discharged from the fuel induction pipe 135 has a very high pressure, there is a possibility that the fuel is not smoothly moved and the backflow may occur. In order to solve such a problem, a branch hole 310 extending in a diagonal direction is provided at one side of the discharge port 300, and a backflow prevention line 110 for preventing back flow of fuel is provided at one side of the branch hole 310, Respectively. For example, the backflow prevention line 110 may guide the fuel to move only to the crushing hole mounting hole 150 through a structure such as a fixing tab formed on the top. Accordingly, a portion of the fuel having a high pressure moves along the branch hole 310 to the backflow prevention line 110. [

The backflow prevention line 110 and the crushing hole mounting hole 150 are connected to each other by the crushing hole guide passage 101. That is, when the amount of the fuel transferred to the backflow prevention line 110 increases, the fuel can be moved to the pulverizing port guide path 310. The movement of the fuel is described as follows.

The backflow prevention line (110) is equipped with a backflow prevention ball (113) elastically supported by a spring (111). Therefore, if the pressure of the fuel flowing into the backflow prevention line 110 through the branch hole 310 is relatively larger than the elastic force of the spring 111 elastically supporting the backflow preventing ball 113, The fuel introduced into the fuel tank 110 presses the backflow prevention balls 113 in the direction in which the spring 111 is compressed. In this case, when the backflow prevention ball 113 passes over the crusher guiding passage 310 due to the pressure of the fuel flowing into the backflow preventing line 110, fuel such as diesel oil flows through the crusher- So that it can move along the passage 310 to the crusher mounting hole 150.

A plurality of crushing holes 158 and 159 are mounted in the crushing hole mounting hole 150 so as to atomize the fuel. Hereinafter, the plurality of mills 158 and 159 will be described with reference to FIGS. 3 and 4. FIG.

FIG. 4 is an enlarged view showing part A of FIG. 3, and is a view showing the plurality of mills.

3 and 4, a crushing port disposed in the crushing hole mounting hole 150 inside the housing 100 is disposed adjacent to the inlet port 200 to communicate with the inlet port 200, A primary crushing unit 159 for primarily crushing the particles and a primary crushing unit 159 for linearly crushing the particles of the fuel that have passed through the primary crushing unit 159 in the longitudinal direction And a secondary pulverizer 158 disposed therein.

The secondary pulverizing means 158 includes a rotary shaft 153 for providing a rotation center and a plurality of helical grooves 151a for crushing fuel particles on the outer surface of the secondary pulverizing means 158, (Hereinafter, referred to as a reverse warp spiral groove) (hereinafter referred to as a reverse warp spiral groove) inclined in the other direction around the rotation shaft 153 is formed on the outer surface of the vortex induction grinder 151, 152a are formed.

The fixed inclined spiral groove 151a and the inverted inclined spiral groove 152a may extend at different angles with respect to the extending direction of the rotation shaft 153. [ For example, the fixed spiral groove 151a may guide the moving direction of the fuel to be clockwise, and the inverted spiral groove 152a may guide the moving direction of the fuel to be counterclockwise .

Likewise, the primary grinder 159 includes an inverse vortex induction grinder 155 having a swirl axis 156, a vortex induction grinder 154 having a constant angled spiral groove 154a, and a reverse gradient spiral groove 155a. . Since the primary pulverizer 159 has the same configuration as the secondary pulverizer 158, a detailed description thereof will be omitted.

Between the primary pulverizing means 159 and the secondary pulverizing means 158, the pulverizing means guide path 101 extending in the width direction perpendicular to the longitudinal direction is provided. Therefore, the particles of the fuel moved along the crusher guiding passage 101 may move to the secondary crusher 158 and be further crushed. That is, the fuel flowing along the inlet port 200 passes through the primary crushing port 159 and the secondary crushing port 158 in order to crush the fuel, and the backflow preventing line 110, The fuel that has passed through the crusher guide passage 101 to the crusher mounting hole 150 may be passed through the secondary crusher 158 to crush the fuel.

Further, the rotation shaft 156 of the primary pulverizer and the rotation shaft 153 of the secondary pulverizer may rotate at different speeds. Accordingly, the rotation speeds of the primary pulverizer 159 and the secondary pulverizer 158 are different from each other, and it is possible to induce vigorous vortexing of the fuel more actively.

As another example, the rotation shaft 156 of the primary pulverizer and the rotary shaft 153 of the secondary pulverizer may be integrally manufactured so that the rotational speeds of the primary pulverizer 159 and the secondary pulverizer 158 May be configured identically.

The fuel that has passed through the plurality of pulverizers 158 and 159 is transferred to the fuel induction pipe 135. Hereinafter, the fuel induction pipe 135 will be described with reference to FIGS. 3 and 5. FIG.

5 is an external perspective view showing the shape of one of the plurality of fuel induction pipes.

3 and 5, the fuel induction pipe 135 is disposed in the fuel induction pipe mounting hole 130 in the housing 100 with a plurality of fuel induction pipes overlapped with each other. The fuel induction pipe 135 includes a fuel inducing inner pipe 131 disposed at the innermost portion and a plurality of fuel inducing outer pipes 133 surrounding the outer surface of the fuel inducing inner pipe 131. For example, the fuel induction furnace 133 may be composed of six fuel manifolds. That is, the fuel induction pipe 135 may be disposed in the fuel induction pipe mounting hole 130 in a state where a total of seven pipes are superposed on each other or in a state where they are surrounded with each other. With this configuration, the exhaust gas reduction device 50 can be applied to a medium or large diesel engine (about 3,000 hp).

Each of the fuel induction pipes 135 is provided with a plurality of guide grooves 135a recessed inwardly from the outer surface thereof in order to further atomize the fuel that has passed through the crushers 158 and 159, And a plurality of through-holes 135b that are perforated from the outer side to the inner side to guide the movement of the fuel along the direction.

The plurality of guide grooves 135a are formed on the outer surface of the fuel induction pipe 135 so that vortices of the fuel are more actively generated. Further, the plurality of through holes 135b guide the fuel moving along one fuel induction pipe of the plurality of fuel induction pipes 135 to move to another fuel induction pipe wrapped inside the one fuel induction pipe . The passage of the fuel is changed in the width direction from the longitudinal direction by the through hole 135b, so that the swirling phenomenon of the fuel can be more actively performed.

In another embodiment, the fuel inducing inner pipe 131 may be replaced with an auxiliary ceramic block, or an auxiliary ceramic block may be mounted on the inner surface of the fuel inducing inner pipe 131. The auxiliary ceramic block may further include a fuel guide path around the outer diameter side of the center portion and a branch path connected to the fuel guide path while being inclined.

Accordingly, the quartz glass provided in the ceramic by the auxiliary ceramic block, that is, anhydrous silicic acid, aluminum oxide and iron oxide reacts with the fuel to perform ion exchange with the heavy metal, so that the harmful metal can be removed, So that the incomplete combustion of the fuel can be prevented.

Hereinafter, the process of moving the fuel such as diesel oil injected from the fuel tank to the engine will be described with reference to FIGS. 2 to 5. FIG.

First, the fuel injected from the fuel tank flows into the ceramic block mounting hole 170 along the inlet port 200. In the ceramic block mounting hole 170, a plurality of ceramic blocks 171 made of elbow stone, sericite, and calcined body are mounted. At this time, the fuel is activated through the plurality of ceramic blocks 171 before being injected into the crushers 158 and 159.

The ceramic block 171 is formed with a fuel injection hole passing through the outer surface thereof so that the diameter gradually decreases during the lamination. As the contact area of the fuel with respect to the ceramic is increased by the fuel injection hole, the fuel can be injected sequentially so that the crushing effect can be enhanced.

The fuel that has passed through the ceramic block 171 is atomized while sequentially passing through the primary pulverizer 159 and the secondary pulverizer 158. Specifically, the fuel is supplied to the inverse warp spiral groove 155a of the reverse vortex induction crusher 155 of the primary crusher 159, the positive inclination spiral 155a of the vortex induction crusher 154 of the primary crusher 159, A groove 154a of the secondary pulverizer 158 and an inverted inclined spiral groove 152a of the secondary vortex inducing pulverizer 152 of the secondary pulverizer 158 and a forward inclined spiral groove 152a of the vortex inducing pulverizer 151 of the secondary pulverizer 158, The fuel can be swirled vigorously while sequentially passing through the first passage 151a. In addition, as the rotation shaft 156 of the primary pulverizer and the rotary shaft 153 of the secondary pulverizer rotate at different rotational speeds, vortices of the fuel may be more active.

However, a small amount of the fuel may be moved along the outer surface of the rotary shaft 156 of the primary pulverizer or the rotary shaft 153 of the secondary pulverizer. These fuels may move along the crusher guiding passage 101 connected to the backflow prevention line 110 for further atomization and then moved to the secondary crusher 158 again. This will be explained later.

The fuel that has passed through the crushers 158 and 159 moves to the fuel induction pipe 135 along the induction passage 103 connecting the crusher mounting hole 150 and the fuel induction pipe mounting hole 130 . Specifically, the fuel moved to the fuel induction pipe 135 moves along the outer or inner surface of the fuel induction inner pipe 131 and the outer surface or the inner surface of the fuel induction outer pipe 133. The plurality of fuel induction outer tubes 133 and the fuel induction inner tubes 131 are disposed in the fuel induction tube mounting hole 130 while overlapping each other. The fuel guiding inner tube 131 and the fuel guiding outer tube 133 are provided with a plurality of guide grooves 135a formed on the outer surface thereof to generate a vortex when the fuel moves and a plurality of through holes (135b) are formed. Accordingly, fuel passing through the fuel induction pipe 135 can be further atomized and injected into the engine along the exhaust port 300.

However, the fuel moving along the inside of the fuel guiding inner pipe 131 or the fuel moving along the outer surface of the rotary shaft 156 of the primary pulverizer or the rotary shaft 153 of the secondary pulverizer is sufficiently atomized The backflow may occur during the movement of the fuel. Therefore, a backflow prevention line 110 for preventing backflow of fuel is installed at one side of the discharge port 300.

The fuel which has been moved to the backflow prevention line 110 along the branch hole 310 by the high pressure is supplied to the backflow prevention line 110 which is installed inside the backflow prevention line 110 and is elastically supported by the spring 111 The backflow is prevented. However, when the pressure of the fuel that presses the backflow prevention balls 111 is relatively larger than the elastic force of the spring 111, the spring 111 is compressed. The fuel flowing along the backflow prevention line 110 flows into the crush hole mounting hole 150 when the backflow prevention ball 111 passes over the crusher guiding passage 101 as the spring 111 is compressed. . Accordingly, the fuel that has been moved to the crusher mounting hole 150 can be atomized again while passing through the secondary crusher 158 and the fuel induction pipe 135.

As described above, the exhaust gas abatement apparatus 50 according to the present invention includes a backflow prevention line 110, a fuel induction pipe mounting hole 130, a crushing hole mounting hole 150, a ceramic block mounting hole 150, (170) are provided so as to be connected to each other, leakage of oil due to an external factor or a pressure at the time of passage of a high-pressure fluid can be completely prevented.

Since the exhaust gas abatement device 50 is constructed as an assembled type, it is easy to manufacture and the weight of the exhaust gas abatement device 50 is reduced.

Accordingly, the present invention has an advantage that it can be applied to a medium or large diesel engine (about 3,000 horsepower class).
