1 is a cross-sectional view illustrating a state of use conceptually illustrating a state in which an exhaust gas purification device 100 is connected to a combustion device BN according to some embodiments of the present disclosure. 2 is a perspective view of the exhaust gas purification apparatus 100 of FIG. 1, FIG. 3 is a perspective view of the baffle B of the exhaust gas purification apparatus 100 of FIG. 1, and FIG. 4 is a baffle of FIG. 3. It is sectional drawing of the IV-IV cutting line of (B).

First, as shown in FIGS. 1 to 4, the exhaust gas purification apparatus 100 according to some embodiments of the present invention is connected to a combustion apparatus BN and is generated in the combustion apparatus BN to generate a combustion duct. The apparatus is installed to actively respond to various types of exhaust gas discharged to the outside along the BD, and includes a first duct part 10, a first foreign matter accommodating part 30-1, and a second one. The foreign material accommodating part 30-2, the 2-1 duct part 20-1, the 2-2 duct part 20-2, and the baffle B may be included.

For example, as illustrated in FIG. 1, the first duct part 10 communicates with the combustion duct BD, and may be formed in an ash or unburned state in the form of powder or solids generated after combustion. The first duct shown as guiding the exhaust gas G1 containing the foreign matter 1 such as fuel material, incombustible non-combustible material, nitrogen compound, and carbon compound in a first direction (downward in FIG. 1). The part 10 may have a rectangular cylindrical shape, but may be variously formed, such as a cylinder and a pipe.

Here, although the exhaust gas G1 is not swirl flow, the exhaust gas G1-1 is biased to one side by the swirl flow generated in the combustion duct BD and the exhaust gas G1-2 is biased to the other side. The discharge gases G1-1 and G1-2 may form a left airflow or a right airflow, for example, so that the flow rates thereof may be different from each other.

For example, the first foreign matter accommodating portion 30-1 is formed on a portion of the bottom surface of the first duct portion 10, and the exhaust gas G1-1 is biased toward one of the exhaust gases G1. In order to receive and discharge the foreign matter (1) contained in the), it may be a funnel-shaped hopper (concave down) concave down so that the foreign matter (1) is laminated downward.

In addition, for example, the second foreign matter accommodating part 30-2 is formed at the other bottom portion of the first duct part 10, and the exhaust gas G1 is biased toward the other side of the exhaust gas G1. To receive and discharge the foreign matter 1 contained in -2), the foreign matter 1 may be a funnel-shaped hopper recessed downward so that the foreign matters 1 are stacked downward.

Here, the first foreign matter receiving portion 30-1 and the second foreign matter receiving portion 30-2 may be installed to be next to each other side by side, in addition to a plurality of further connected to remove the foreign matter (1) of the equipment It can play a role in increasing performance.

In addition, the 2-1 duct portion 20-1 is in communication with the first purge gas discharge port (H1) formed on one side of the side of the first duct portion 10, purification of the foreign matter 1 is separated Inducing a part of the gas (G2) in the second direction (the right direction in FIG. 1), the 2-1 duct portion 20-1 shown is a rectangular cylindrical shape, in addition to a cylindrical, pipe shape, etc. Can be formed.

Here, the second direction is the discharge gas (G1) or purifying gas (G2) before finally discharged to the discharge gas (G1) or purifying gas (G2) flowing through the first duct portion 10 to the outside ) May be directed to a processing device for treating harmful components of In this case, the treatment apparatus may be a selective catalytic reduction facility, and the exhaust gas G1 or the purge gas G2 introduced in the second direction may be led to a catalyst layer constituting the selective catalytic reduction facility.

For example, the 2nd-2 duct part 20-2 communicates with the 2nd purification gas discharge port H2 formed in the other side surface of the 1st duct part 10, and the foreign material 1 is isolate | separated. Inducing the other part of the purified gas G2 in the third direction, the 2-2 duct portion 20-2 shown in the figure may be formed in a variety of cylinders, pipes, etc. in addition to the rectangular cylinder shape. .

Here, the third direction, before the discharge gas (G1) or purge gas (G2) flowing through the first duct portion 10 to the final discharge to the outside (purification gas (G1) or purge gas ( It may be a direction entering the processing device for treating the harmful component of G2). In this case, the treatment apparatus may be a selective catalytic reduction facility, and the exhaust gas G1 or the purge gas G2 introduced in the third direction may be led to a catalyst layer constituting the selective catalytic reduction facility.

Meanwhile, as illustrated in FIGS. 1 to 4, the baffle B sharply changes the air flow direction of the exhaust gas G1 so that the foreign matters 1 included in the exhaust gas G1 can be easily separated. As shown in FIG. 2, the baffle B may include a first-first baffle B1 and a second-first baffle B2.

For example, as shown in FIG. 2, the air flow direction of a part of the exhaust gas G1 introduced into the first duct part 10 is in the first-1 baffle B1. It may be a plate-like structure that leads to a sharp change in the direction of the negative portion 20-1.

For example, as illustrated in FIG. 2, the air flow direction of the other part of the exhaust gas G1 introduced into the first duct part 10 may have the second air flow direction in the second 1-2 baffles B2. It may be a plate-like structure that leads to a rapid change in the direction of the -2 duct portion 20-2.

More specifically, for example, as shown in FIGS. 3 and 4, the first length of the first baffle B1 may have a first length such that the tip thereof is inclined downward in the direction of the first foreign matter receiving portion 30-1. It protrudes convexly to L1, a rear end is fixed above the said 1st purification gas discharge port H1, and the said 1-2 baffle B2 has a front-end | tip with the said 2nd foreign matter accommodating part 30-2. Inclined downward in a direction to a second length L2 shorter than the first length L1, the rear end is fixed above the second purge gas outlet H2, and the first-1 baffle ( B1) and the first and second baffles B2 may be connected to each other in an integrated plate shape.

Accordingly, the baffle B may be configured to change the direction of the discharge gas G1 introduced into the first direction through the first duct part 10 into the second-1 duct part 20-1 or the second-2-2. It may be induced to change rapidly in the direction of the duct portion 20-2. That is, the discharge gas G1 introduced through the first duct part 10 flows in the first direction (downward in FIG. 1), and then the direction of air flow is changed by the baffle B in the second-1 duct. It may be rapidly switched to the second direction and the third direction which is the direction to the part 20-1 or the second-2 duct part 20-2. When such a sudden change of direction of the air flow occurs, the foreign matter 1 having a predetermined mass contained in the exhaust gas G1 tends to continue to move in the first direction by inertia (or centrifugal force). It does not correspond to the change of direction and is separated from the exhaust gas G1 as it is moved toward the first foreign matter receiving portion 30-1 or the second foreign matter receiving portion 30-2. Therefore, most of the foreign matter 1 is accommodated in the first foreign matter receiving portion 30-1 or the second foreign matter receiving portion 30-2 by the sudden change of air flow induced by the baffle B. FIG. The foreign matter 1 may be removed from the 2-1 duct part 20-1 or the 2-2 duct part 20-2, and only the purified purifying gas G2 may be discharged to the outside. Can be.

In this case, the baffle B corresponds to the discharge gas G1-1 (G1-2) having different flow rates, for example, when the left flow rate is large, the discharge gas G1 having a greater amount of kinetic energy. The shape of the first-first baffle B1, which first collides with -1), protrudes relatively longer, and its tip can be formed convex to disperse the enhanced airflow, and a smaller amount of kinetic energy The first and second baffles B2 which later collide with the discharge gas G1-2 having a shape may protrude relatively shorter, and the tip may be concave so as to disperse the weakened air flow. . In addition, such a flat plate shape is very simple to manufacture can reduce the manufacturing cost and manufacturing time.

Therefore, the amount of the foreign matter 1 accommodated in the first foreign matter receiving portion 30-1 and the second foreign matter receiving portion 30-2 can be similarly matched by differentiation of the baffle shape so as to correspond to the shape of the small stones. This improves the separation performance of foreign substances, and helps the equipment operation by uniformizing the flow rate between the rear end duct, and can easily increase the capacity of the equipment, and greatly improve the productivity and efficiency of the equipment.

However, the shape of the baffle B is not necessarily limited to the drawings, and all types of baffles formed in a different form may be applied to correspond to exhaust gases G1-1 and G1-2 having different flow rates. have.

Protrudes to the first length L1 inclined downward, and the rear end is fixed above the first purge gas discharge port H1, and the second 1-2 baffle B2 has a front end of the second foreign matter accommodating part. Protrudes to a second length L2 shorter than the first length L1 and inclined downward in the direction of (30-2), and a rear end is fixed above the second purge gas discharge port H2, and the first The baffle B1 and the first and second baffles B2 may be connected to each other on an integrated flat plate.

Accordingly, the baffle B may first collide with, for example, the exhaust gas G1-1 having a greater amount of kinetic energy so that the flow rates correspond to different exhaust gases G1-1 and G1-2. The shape of the first-first baffle B1 protrudes relatively longer so that its tip can disperse the enhanced airflow and later collides with the exhaust gas G1-2 having a smaller amount of kinetic energy. The shape of the 1-2 baffles B2 protrudes relatively shorter, and its tip can disperse the weakened air flow. In addition, such a flat plate shape is very simple to manufacture can reduce the manufacturing cost and manufacturing time.

Therefore, the amount of the foreign matter 1 accommodated in the first foreign matter receiving portion 30-1 and the second foreign matter receiving portion 30-2 can be similarly matched by the differentiation of the baffle shape so as to correspond to the vortex stone. This improves the separation performance of foreign substances, and helps the equipment operation by uniformizing the flow rate between the rear end duct, and can easily increase the capacity of the equipment, and greatly improve the productivity and efficiency of the equipment.

Accordingly, the baffle B is relatively convexly curved in the shape of the first-first baffle B1 that first collides with the exhaust gas G1-1 having a greater amount of kinetic energy, and thus the tip thereof is bent. The shape of the first and second baffles B2, which later collides with the exhaust gas G1-2 which has a smaller amount of kinetic energy, can be dispersed first, and thus the enhanced airflow can be dissipated relatively convexly. It may later disperse the weakened air stream. In addition, this curved curved sheet shape is very simple to manufacture can reduce the manufacturing cost and manufacturing time.

Therefore, by differentiating the baffle shape, the amount of the foreign matter 1 accommodated in the first foreign matter receiving portion 30-1 and the second foreign matter receiving portion 30-2 can be similarly matched, thereby separating foreign matter. In addition, it helps to operate the equipment by uniformizing the flow rate between the rear end duct, and can easily increase the capacity of the equipment, and can greatly improve the productivity and efficiency of the equipment.
