[0004] However, if this exhaust gas reduction device (1) is used for a long time, pollutants contained in the exhaust gas accumulate inside the exhaust gas reduction filter (3), and the performance deteriorates.

[0005] Therefore, after using this exhaust gas reduction device (1) for a certain period of time, a regeneration process is performed to remove contaminants attached to the exhaust gas reduction filter (3).

[0006] In this way, when regenerating the exhaust gas reduction device (1), a method is mainly used in which cleaning water is injected into the interior of the housing (2) through the inlet (2a) to wash away contaminants attached to the exhaust gas reduction filter (3).

[0007] However, since the process of washing the exhaust gas reduction filter (3) is mainly done manually, there was a problem that the work was very cumbersome.

[0008] In addition, after washing off the contaminants attached to the exhaust gas reduction filter (3) in this manner, the exhaust gas reduction filter (3) must be dried and the differential pressure measured, but since these operations are carried out by separate devices, the problem of the work being very cumbersome arises.

[0009] Therefore, a new method to solve these problems became necessary. Prior art literature

[0022] The main body (10) is configured in the shape of a square box, and the front of the washing room (13) is open.

[0023] At this time, the main body (10) is provided with an upper plate (16) positioned above the horizontal plate (11), so that an upper chamber (17) is formed above the washing chamber (13).

[0024] In addition, a communication hole (11a) connecting the washing room (13) and the water storage room (14) is formed in the horizontal plate (11), and a filter member (11b) is provided on the lower side of the communication hole (11a).

[0025] In addition, a lamp (42) and a ventilation fan (43) are provided on the upper part of the washing chamber (13) of the main body (10).

[0026] The support case (21) is configured as a cylindrical shape with a larger diameter than the exhaust gas reduction device (1) and an open lower side, and is fixed to the upper surface of the horizontal plate (11) to cover the upper part of the communication hole (11a).

[0027] The above connecting member (22) is configured in a funnel shape, with the inner diameter increasing towards the lower side and a supply hole (22a) formed in the center of the upper surface to which the discharge pipe (28) is connected.

[0028] At this time, the diameter of the lower part of the connecting member (22) is configured to be larger than the diameter of the exhaust gas reduction device (1).

[0029] The above lifting cylinder (23) utilizes an air cylinder that extends downward from the upper partition plate (16) and has a piston rod provided on the lower side fixed to the upper surface of the connecting member (22) so that the connecting member (22) is raised and lowered according to the extension and extension.

[0030] The filter unit (24) is fixed to the outside of the main body (10), and is configured to have a supply port (24a) formed on one side and a discharge port (24b) formed on the lower side, so as to filter the cleaning liquid supplied through the supply port (24a) to remove contaminants and then discharge it through the discharge port (24b).

[0031] The above water supply pump (25) uses a submersible motor positioned inside the water storage room (14) to be submerged in the washing water stored in the water storage room (14).

[0032] The first water supply pipe (25a) above connects the water supply pump (25) and the supply port (24a) of the filter unit (24).

[0033] The above three-way valve (27) is operated by the control means (36) and configured to selectively connect the first supply port (27a) and the second supply port (27b) to the discharge port (27c).

[0034] At this time, the three-way valve (27) and heater (31) are provided inside the upper chamber (17).

[0035] The above control means (36) is equipped with an input means (37) and configured so that an operator inputs a control command to the control means (36) by operating the input means (37).

[0036] At this time, the heating temperature, target humidity, and cooling temperature are input to the control means (36).

[0037] The above differential pressure measuring device (38) is placed on the upper surface of the exhaust gas reduction filter (3) provided in the exhaust gas reduction device (1), and when air is supplied through the branch pipe (39), it measures the differential pressure of the exhaust gas reduction filter (3), that is, the resistance generated when air passes through the exhaust gas reduction filter (3), and is configured to measure the degree to which contaminants attached to the exhaust gas reduction filter (3) are removed.

[0038] Since various types of such differential pressure measuring devices (38) have been developed and are in use, further detailed explanation regarding them is omitted.

[0039] The operation of the hydraulic cleaning device of the exhaust gas reduction device configured in this manner is explained as follows.

[0040] First, as shown in FIGS. 2 and 3, after the operator places the exhaust gas reduction device (1) on the support case (21) and inputs a cleaning command by operating the input means (37), the control means (36) controls the lifting cylinder (23) as shown in FIG. 5 to lower the connecting member (22) so that the connecting member (22) is coupled to the upper surface of the exhaust gas reduction device (1).

[0041] And, the control means (36) controls the water supply pump (25), ring blower (26), and three-way valve (27) so that the cleaning water and air are supplied to the exhaust gas reduction device (1) through the connecting member (22) to clean the exhaust gas reduction filter (3) of the exhaust gas reduction device (1).

[0042] At this time, the washing water that washes the soot reduction filter (3) while passing through the soot reduction filter (3) passes through the discharge hole (21a) of the support case (21) and the communication hole (11a) of the horizontal plate (11) and is discharged into the water storage room (14).

[0043] And, the control means (36) controls the three-way valve (27) according to the cleaning method input by the operator through the input means (37) so that cleaning water and air are supplied alternately to the connecting member (22), or so that cleaning water and air are supplied together to the exhaust gas reduction device (1) through the connecting member (22).

[0044] And, when a preset time has elapsed, the control means (36) stops the water supply pump (25) and controls the ring blower (26), the three-way valve (27), and the heater (31) so that high-temperature air is supplied to the exhaust gas reduction device (1) through the connecting member (22) to dry the exhaust gas reduction device (1).

[0045] At this time, the control means (36) controls the heater (31) while feeding back the signal of the inlet temperature sensor (32) so that the temperature of the air supplied to the connecting member (22) is maintained at a pre-entered heating temperature ± 3 degrees.

[0046] And, the control means (36) receives a signal from the pressure sensor (35) and checks the degree to which contaminants attached to the exhaust gas reduction filter (3) have been washed.

[0047] That is, when the contaminants attached to the above-mentioned exhaust gas reduction filter (3) are sufficiently washed, the air supplied by the ring blower (26) passes smoothly through the exhaust gas reduction filter (3), so the air pressure inside the air supply pipe (30) measured by the pressure sensor (35) is lowered; conversely, when the contaminants attached to the above-mentioned exhaust gas reduction filter (3) are not sufficiently washed, the air supplied by the ring blower (26) does not pass smoothly through the exhaust gas reduction filter (3), so the air pressure inside the air supply pipe (30) measured by the pressure sensor (35) is raised.

[0048] Accordingly, if the air pressure inside the air supply pipe (30) measured by the pressure sensor (35) is higher than the reference pressure set in advance, it is determined that the contaminants attached to the exhaust gas reduction filter (3) have not been sufficiently washed, and the control means (36), as described above, supplies water and air to the exhaust gas reduction filter (3) to perform a washing operation to remove the contaminants attached to the exhaust gas reduction filter (3) so that the contaminants are sufficiently removed, and then supplies high-temperature air to the exhaust gas reduction filter (3) to perform a drying operation to dry the exhaust gas reduction filter (3).

[0049] And, the control means (36) receives a signal from the humidity sensor (34), and when the humidity inside the support case (21) reaches the target humidity, it determines that the exhaust gas reduction filter (3) is sufficiently dried and stops the heater (31).

[0050] And, the control means (36) drives the ring blower (26) to continuously supply air to the connecting member (22), thereby allowing the exhaust gas reduction device (1) to be cooled by the air.

[0051] And, the control means (36) stops the ring blower (26) to complete the operation when the temperature inside the support case (21) reaches a pre-entered cooling temperature.

[0052] Then, when a worker places a differential pressure measuring device (38) on the exhaust gas reduction filter (3) of the exhaust gas reduction device (1) placed on the support case (21) and inputs a differential pressure measurement command by operating the input means (37), the control means (36) drives the ring blower (26) and opens the air supply control valve (41) to supply air to the differential pressure measuring device (38), thereby measuring the differential pressure of the exhaust gas reduction filter (3).

[0053] The hydraulic cleaning device of the exhaust gas reduction device configured in this manner has the advantage of making it very easy to clean and dry the exhaust gas reduction device, as the operator places the exhaust gas reduction device (1) on the support case (21) and then inputs a cleaning command by operating the input means (37), the control means (36) automatically controls the water supply pump (25), ring blower (26), three-way valve (27), and heater (31) to supply cleaning water and air to the exhaust gas reduction device (1), thereby cleaning and drying the exhaust gas reduction device (1).

[0054] In addition, by using a differential pressure measuring device (38) provided in the main body (10) to measure the differential pressure of the exhaust gas reduction device (1), there is an advantage in that the differential pressure of the exhaust gas reduction filter (3) can be measured without undergoing a cleaning process. While the above pressure sensor (35) is used to check the degree to which the exhaust gas reduction filter (3) is cleaned during the cleaning process, the above differential pressure measuring device (38) can be used to check whether cleaning is necessary by measuring the differential pressure of the exhaust gas reduction filter (3) that has not undergone a cleaning process and checking how clogged the exhaust gas reduction filter (3) is.

[0055] FIGS. 7 to 9 illustrate a second embodiment according to the present invention, wherein an exhaust hole (18) is formed on the rear side of the washing chamber (13) of the main body (10), and an exhaust pipe (19) extending to the rear of the main body (10) is provided in the exhaust hole (18).

[0056] In addition, the above-mentioned support case (21) and an insulation panel (44) that surrounds the perimeter of the exhaust gas reduction device (1) placed on the support case (21), a lifting driving means (45) connected to the insulation panel (44) to raise and lower the insulation panel (44), and an exhaust fan (45) provided in the exhaust pipe (19) are further provided.

[0057] As shown in FIG. 8, the above insulation panel (44) is formed by bending an insulation material panel into a U-shape, and is composed of a bending part (44a) that wraps around the front perimeter of the support case (21) and the exhaust gas reduction device (1) placed on the support case (21), and an extension part (44b) that extends backward from both ends of the bending part (44a), and the vertical height is configured to be slightly lower than the height of the washing room (13).

[0058] At this time, guide rails (44c) extending in the vertical direction are provided on both sides of the rear side of the washing chamber (13) of the main body (10), and the extension part (44b) is slidably coupled to the guide rails (44c) in the vertical direction.

[0059] Additionally, a U-shaped cut (16a) corresponding to the insulation panel (44) is formed in the upper plate (16), so that the insulation panel (44) is configured to rise into the interior of the upper chamber (17) through the cut (16a).

[0060] And, the exhaust hole (18) is formed to be located between the extensions (44b) of the insulation panel (44).

[0061] The above lifting drive means (45) utilizes a cylinder mechanism connected to the insulation panel (44) to cause the insulation panel (44) to be raised or lowered according to the extension, thereby raising the upper end of the insulation panel (44) into the interior of the upper chamber (17) or lowering the lower side of the insulation panel (44) so ​​as to be in close contact with the lower side of the interior of the washing room (13).

[0062] And, when the above control means (36) cleans the above exhaust gas reduction device (1), as shown in FIG. 9, it controls the lifting drive means (45) to lower the insulation panel (44) that has been raised into the interior of the upper chamber (17) so that the insulation panel (44) wraps around the perimeter of the support case (21) and the exhaust gas reduction device (1) placed on the support case (21).

[0063] Accordingly, when high-pressure water and air are supplied to the connecting member (22) while the connecting member (22) is attached to the top of the exhaust gas reduction device (1) placed on the upper surface of the support case (21), if the water or air is scattered to the surroundings through the gap between the connecting part and the exhaust gas reduction device (1) or the gap between the exhaust gas reduction device (1) and the support case (21), the water or air can be prevented from colliding with the inner surface of the insulation panel (44) and scattering to the surroundings, thereby preventing the surroundings from being contaminated by the water or air.

[0064] And, when drying and cooling the exhaust gas reduction device (1), the control means (36) drives the exhaust fan (45) while the insulation panel (44) is lowered so that the heated air around the exhaust gas reduction device (1) is discharged to the outside.

[0065] That is, when drying or cooling the above-mentioned exhaust gas reduction device (1), the above-mentioned exhaust gas reduction device (1) is heated to a high temperature, and the surrounding temperature rises due to the heat generated from the exhaust gas reduction device (1), and the working environment deteriorates.

[0066] At this time, when the exhaust fan (45) is driven while the insulation panel (44) is lowered, the heat generated from the exhaust gas reduction device (1) is not only blocked by the insulation panel (44), but the air around the exhaust gas reduction device (1) is discharged to the outside through the exhaust pipe (19), and the temperature from the outside is introduced into the interior of the insulation panel (44), thereby preventing the surrounding temperature from rising due to the heat generated from the exhaust gas reduction device (1) and maintaining a comfortable working environment.

[0067] The hydraulic cleaning device of the exhaust gas reduction device configured in this manner has the advantage of preventing the working environment from deteriorating due to cleaning water, air, or heat during cleaning or drying operations by arranging an insulating panel (44) to surround the perimeter of the support case (21) and the exhaust gas reduction device (1) placed on the support case (21).
