A hydraulic cleaning apparatus for a particulate matter reduction device that is for cleaning a particulate matter reduction device (1) including a housing (2) which extends in a vertical direction and in which an inlet (2a) and an outlet (2b) are formed at upper and lower ends thereof and a particulate matter reduction filter (3) provided inside the housing (2), the hydraulic cleaning apparatus comprising:

• a main body (10) which is formed in a box shape with an internal space and in which the internal space is divided into a cleaning room (13), a water storage room (14), and a machine room (15) by a horizontal partition (11) and a vertical partition (12) provided therein, wherein a communication hole (11a) connecting the cleaning room (13) to the water storage room (14) is formed in the horizontal partition (11);
• a support case (21) which is provided in the cleaning room (13) of the main body (10) for the particulate matter reduction device (1) to be placed on an upper surface thereof and which has a discharge hole (21a) formed in the upper surface;
• a connecting member (22) provided on an upper portion of the support case (21) and moved upward and downward by an elevating cylinder (23) to be coupled to an upper end of the particulate matter reduction device (1) placed on the support case (21);
• a filter unit (24) provided on one side of the main body (10);
• a water supply pump (25) which is provided in the water storage room (14) and connected to the filter unit (24) by a first water supply pipe (25a) so as to press cleaning water stored in the water storage room (14) and supply the pressed cleaning water to the filter unit (24);
• a ring blower (26) provided inside the machine room (15);
• a three-way valve (27) having first and second supply port (27a, 27b) and a discharge port (27c), wherein the first supply port (27a) is connected to the filter unit (24) through a second water supply pipe (29), the second supply port (27b) is connected to the ring blower (26) through an air supply pipe (30), and the discharge port (27c) is connected to the connecting member (22) through a discharge pipe (28), and controlling cleaning water that has passed through the filter unit (24) or air supplied from the ring blower (26) to be supplied to the connecting member (22) through the discharge pipe (28) according to an operation;
• a heater (31) provided on a middle portion of the air supply pipe (30) to heat air supplied through the air supply pipe (30);
• an inlet temperature sensor (32) which is provided on the connecting member (22) and measures a temperature of air inside the connecting member (22);
• an outlet temperature sensor (33) which is provided inside the support case (21) and measures a temperature of air discharged to the support case (21);
• a humidity sensor (34) which is provided inside the support case (21) and measures humidity of the air discharged to the support case (21);
• a differential pressure sensor (35) which is provided on the air supply pipe (30) and measures a pressure of the air supplied through the air supply pipe (30);
• a branch pipe (39) branched from the air supply pipe (30);
• a differential pressure gauge (38) connected to the branch pipe (39);
• an air supply control valve (41) provided on the branch pipe (39);
• and
• a control unit (36) which receives signals of the inlet temperature sensor (32), the outlet temperature sensor (33), the humidity sensor (34), and the differential pressure sensor (35) and controls operations of the elevating cylinder (23), the water supply pump (25), the ring blower (26), the three-way valve (27), the heater (31), and the air supply control valve (41).
