[0028] Reference Figure 3 The liquid inlet end of the liquid inlet pipe 3 passes through the mounting hole on the side surface of the filter tank 1 and is placed outside the filter tank 1. A hydraulic rod 2 is fixedly installed at the central axis position of the upper surface of the filter tank 1. The telescopic end of the hydraulic rod 2 is fixedly connected with a scraper plate 17. The scraper plate 17 is placed inside the filter tank 1. A discharge pipe 16 is fixedly connected at the central axis position of the lower surface of the filter tank 1. A control valve is fixedly installed in the pipeline of the discharge pipe 16. The discharge pipe 16 is connected to the inside of the filter cartridge 15. After a period of filtering, the hydraulic rod 2 can be extended. The hydraulic rod 2 drives the scraper plate 17 to slide down along the inner wall of the filter cartridge 15, so that the impurities attached to the inner wall of the filter cartridge 15 can be pushed into the inside of the discharge pipe 16 and discharged from the discharge pipe 16, so that the automatic dredging operation of the filter cartridge 15 can be realized, ensuring that the filter cartridge 15 can always perform efficient filtering operations.

[0029] Reference Figure 2A resistance heating tube 13 is installed inside the evaporation box 10, and an exhaust pipe 12 is fixedly connected to the upper surface of the evaporation box 10. A vacuum pump 11 is fixedly installed in the exhaust pipe 12.

[0030] Working principle: when in use, the device is first installed at a designated position, and then the liquid inlet pipe 3 is used to guide the biogas slurry to be treated into the interior of the filter cartridge 15. After the biogas slurry passes through the filtering operation of the filter cartridge 15, it enters the interior of the filter tank 1, and then the delivery pump 5 is started. At this time, the biogas slurry in the filter tank 1 flows into the interior of the microbial treatment box 6 along the first liquid guide pipe 4. With the continuous influx of the biogas slurry, the biogas slurry can orderly pass through the flow channel between the two adjacent inner substrates 14. At this time, the biogas slurry can fully contact with the microbial colonies attached to the inner substrate 14. In this process, the microbial colonies can effectively perform microbial purification operations on the biogas slurry. The purified biogas slurry flows into the interior of the liquid storage tank 8 along the second liquid guide pipe 7. The liquid storage tank 8 can effectively store the biogas slurry, and then the third liquid guide pipe 9 is used. The biogas slurry in the liquid storage tank 8 is introduced into the evaporation box 10 in batches, and then the resistance heating tube 13 is started to heat the biogas slurry in the evaporation box 10. In this process, the vacuum pump 11 is started to discharge the gas in the evaporation box 10 from the exhaust pipe 12, which can effectively reduce the air pressure in the evaporation box 10, thereby improving the evaporation efficiency of the biogas slurry. After a period of treatment, the control valve on the discharge pipe 16 is opened, and then the hydraulic rod 2 is extended. The hydraulic rod 2 drives the scraper plate 17 to slide down along the inner wall of the filter cartridge 15, thereby pushing the impurities attached to the inner wall of the filter cartridge 15 into the discharge pipe 16 and discharging them from the discharge pipe 16, which can realize the automatic dredging operation of the filter cartridge 15 and ensure that the filter cartridge 15 can always perform efficient filtering operations.
