Description

Technical Field

[0001] This utility model belongs to the field of biogas slurry treatment technology, and in particular relates to a biogas slurry deep purification treatment device. Background Technology

[0002] Biogas slurry refers to the liquid portion produced after the fermentation of organic waste during anaerobic fermentation. It is one of the byproducts of biogas production from the decomposition of organic matter by anaerobic microorganisms. In order to meet emission standards and reduce the risk of pollution to water bodies and soil, biogas slurry is treated with advanced purification equipment before being discharged.

[0003] A utility patent application with publication number CN215403483U discloses an ecological purification and treatment device for biogas slurry in a livestock farm, including a treatment tank, a reaction chamber, and a storage tank. An operation panel with a microprocessor is installed on one side wall of the treatment tank. The sedimentation chamber is installed inside the treatment tank. Through the set reaction chamber, storage tank, solenoid valve, stirring motor, and turbine stirring rod, heavy metals in the biogas slurry can be efficiently separated and desorbed, facilitating subsequent discharge and use without polluting the environment. Through the set support, micro motor, and screw rod, the sedimented biogas slurry residue can be quickly and automatically cleaned out, avoiding clogging of the device and thus improving the working efficiency of the device.

[0004] Although the above scheme has achieved efficient removal of heavy metals and efficient discharge of solid impurities, there are still many shortcomings in its use, such as: (1) Solid impurities in the biogas slurry in the sedimentation chamber rely on static sedimentation, which reduces the classification efficiency. After sedimentation, the pipe will suck the biogas slurry into the reaction chamber. If the suction is too small, it will not be able to suck up all the biogas slurry. When the solid impurities are discharged, some biogas slurry that has not been separated and desorbed by heavy metals will be discharged. If the suction is too large, all the biogas slurry can be sucked into the reaction chamber, but the corresponding suction will destroy the sedimentation state of the solid impurities and make them sucked into the reaction chamber along with the biogas slurry. When the heavy metal adsorbent removes and desorbs the heavy metals, the solid impurities contained in the biogas slurry will change the surface characteristics of the adsorbent, reduce the adsorption efficiency of heavy metals, and increase the difficulty of the treatment process; (2) After the biogas slurry enters the reaction chamber and reacts with the heavy metal adsorbent, it will generate sediment again. It is necessary to add a discharge mechanism again, which wastes energy. In addition, the drawback of the biogas slurry being sucked into the reaction chamber will reappear at the suction pump.

[0005] To address these issues, we provide a biogas slurry deep purification treatment device. Utility Model Content
