When the inner cylinder cleaning mechanism 7 is activated, it enters the interior of the filter cartridge along the axial direction of the filter cartridge and cleans the filter cartridge from the inside to the outside.

[0028] A first spray arm 4 and a second spray arm 6 are also provided in the cleaning chamber 2. The first spray arm 4 and the second spray arm 6 are located on both sides of the filter cartridge, and are located at the upper and lower parts of the filter cartridge respectively. A plurality of spray heads are arranged on the surfaces of the first spray arm 4 and the second spray arm 6. The first spray arm 4 sprays one side of the filter cartridge from top to bottom, and the second spray arm 6 sprays the filter cartridge from bottom to top on the other side of the filter cartridge. An overflow port 9 is provided at the bottom of the cleaning chamber 2 for collecting the sewage after cleaning.

[0029] like Figure 4 As shown, the inner drum cleaning mechanism 7 includes a driving box 14 fixed to the bottom surface of the cleaning chamber 2, and a driving motor and a reducer are arranged in the driving box 14. The output shaft of the reducer is drawn out from the side of the driving box 14 and is coaxially fixed with a driving disk 13. A driving shaft is axially fixed on the surface of the driving disk 13, and a connecting rod mechanism 15 is installed at the driving shaft. The other end of the connecting rod mechanism 15 is connected to the slide 12, and the slide 12 is clamped on the surface of the driving box 14. An inner spray arm 11 is fixed on the upper part of the slide 12. The upper surface of the driving box 14 is an inclined surface, so the inner spray arm 11 is inclined. The inclination direction of the inner spray arm 11 is the same as the inclination angle after the filter cartridge is fixed on the clamping frame 5. A spray head 10 is arranged at the upper end of the inner spray arm 11, and the spray head 10 is directly opposite to the lower end of the filter cartridge.

[0030] When the driving disk 13 rotates, the slide 12 reciprocates along the upper surface of the driving box 14 driven by the connecting rod mechanism 15. During the reciprocating movement of the slide 12, the inner spray arm 11 is driven to reciprocate axially inside the filter cartridge. At the same time, the spray head at the end of the inner spray arm 11 cleans the inside of the filter cartridge.

A clamp 18 for clamping the filter cartridge is fixed at the front end of the arm body. The inclination direction of the filter cartridge can be adjusted by the adjusting arm 17, so that the filter cartridge and the inner spray arm 11 are coaxially arranged, so that the inner spray arm 10 can smoothly reciprocate inside the filter cartridge.

[0032] like Figure 6-7As shown, the main cabinet 3 includes a main frame 20 and a shell fixed to the surface of the main frame 20. A fan 25 is arranged on the upper surface of the main frame 20, and the air outlet of the fan 25 is connected to the heating box 23. An electric heater is arranged in the heating box 23, and the outlet of the heating box 23 is connected to the drying box 21. The drying box 21 is arranged on the surface of the main frame 20 along the length direction of the main frame. A drying port 8 is opened on the side of the rear surface of the above-mentioned cleaning chamber 2, and the outlet of the drying box 21 is connected to the drying port 8. The height of the drying port 8 is higher than the bottom surface of the cleaning chamber 2 to prevent water in the cleaning chamber 2 from flowing back into the drying port 8.

[0033] A waste water tank 28 and a clean water tank 32 are fixed side by side on the bottom plate surface of the main frame 20 , an overflow pipe 29 is led out from the side of the waste water tank 28 , and the overflow pipe 29 extends upward to the bottom of the cleaning chamber 2 and docks with the overflow port 9 .

[0034] A clean water pump 32 is provided on the side of the clean water tank 31, a stirring tank 30 is provided on the side of the clean water pump 32, and a stirrer is provided on the top of the stirring tank 30. The inlet of the clean water pump 32 is connected to the clean water tank 31 through a pipeline, and the outlet of the clean water pump 32 is connected to the stirring tank 30 through a pipeline. A cleaning agent pump 27 is provided on the side of the waste water tank 28, a cleaning agent tank 26 is provided on the side of the cleaning agent pump 27, and a cleaning agent is contained in the cleaning agent tank 26. The inlet of the cleaning agent pump 27 is connected to the cleaning agent tank 26 through a pipeline, and the outlet of the cleaning agent pump 27 is connected to the stirring tank 30 through a pipeline. The clean water pump 32 and the cleaning agent pump 27 are preferably implemented by metering pumps.

[0035] A spray pump 24 is also provided on the surface of the clean water tank 31. The inlet of the spray pump 24 is divided into two routes: one route is connected to the mixing tank 30, and the other route is connected to the clean water tank 31, and electromagnetic valves are provided on the two pipelines. The outlet of the spray pump 24 is connected to a tee, and the other two routes of the tee are respectively connected to the first spray arm 4 and the second spray arm 6. An interface is also connected in parallel to the pipeline from the outlet of the spray pump 24, and the interface is connected to the water inlet (lower port) of the inner spray arm 11 through a hose that runs through the cleaning chamber 2.

[0036] The specific working process and working principle are as follows:

[0037] The staff puts the filter cartridge to be cleaned into the opening of the cleaning chamber 2, clamps it with the clamp 18, and adjusts the inclination angle of the filter cartridge by adjusting the arm 17, so that it is inclined at the same angle as the inner spray arm 11. The inclination is turned on by the control cabinet 1. The control cabinet first controls the spray pump 24 to work, and controls the on and off of the solenoid valve, and pumps the clean water in the clean water tank 31 out through the spray pump 24 and sends it into the spray pipe 22.

[0038] At the same time, the control cabinet 1 controls the motor in the drive box 14 to work, driving the connecting rod mechanism 15 to move, and further drives the inner spray arm 11 to reciprocate along the inside of the filter cartridge through the connecting rod mechanism 15, and sprays from the inside of the filter cartridge through the spray head 10 at the end of the inner spray arm 11. The reciprocating distance of the connecting rod mechanism 15 is 1 / 3 to 2 / 3 of the length of the filter cartridge, and a beaker is placed at the lower end of the filter cartridge in advance, and the flushing liquid flows into the beaker along the inclined filter cartridge, and then the flushing liquid is analyzed through the subsequent process to achieve the sampling of the flue gas.

[0039] After the sampling work is completed, the control cabinet controls the operation of the clean water pump 32 and the cleaning agent pump 27 to pump a certain proportion of clean water and cleaning agent into the stirring tank 30. Then the agitator is controlled to work and configured as a cleaning liquid. The controller controls the operation of the spray pump 24, and by controlling the on and off of the solenoid valve, the cleaning liquid in the stirring tank 30 is first pumped out through the spray pump 24. The cleaning liquid is respectively sent to the first spray arm 4, the second spray arm 6 and the inner spray arm 11 through the spray pipe. The cleaning liquid rinses the outside of the filter cartridge from both sides through the first spray arm 4 and the second spray arm 6. At the same time, the control cabinet 1 controls the operation of the motor in the drive box 14, driving the inner spray arm 11 to move back and forth along the inside of the filter cartridge, and spraying from the inside of the filter cartridge through the spray head 10 at the end of the inner spray arm 11.

[0040] After 30 seconds of cleaning agent spraying, the control cabinet 1 switches the on-off state of the solenoid valve, and the spray pump 24 only sprays the clean water in the clean water tank 31 to clean the filter cartridge for 180 seconds. After cleaning, the control cabinet controls the heater in the heating box 23 to work, and turns on the fan 25 at the same time, and the fan sends the high-temperature gas into the cleaning chamber 2 through the drying port 8 to dry the inner cylinder. The drying temperature is 75~90℃, and the drying time is 300s, and this cycle repeats.
