Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic biogas steam-water separation equipment, in particular to a steam-water separation device for biogas slurry treatment. Background Art

[0002] As people's requirements for environmental protection continue to increase. Anaerobic reactors have been popularized in sewage systems in various industries. The water vapor content in the anaerobic biogas is high, and the water contains impurities, which causes the conventional liquid level gauge to be unable to display normally. Due to the presence of biogas, the liquid level gauge is difficult to clean and there is a great risk. If the water vapor in the biogas is not thoroughly treated, the slag cannot be discharged regularly, and long-term operation will lead to corrosion problems on subsequent equipment, equipment blockage problems, and biogas conveying equipment due to insufficient power and frequent failures due to high water vapor and slag. It is necessary to take other measures at a higher cost, and increase the workload of inspections during normal operation. Therefore, the steam-water separation treatment of anaerobic biogas is particularly important, so a steam-water separation device for biogas liquid treatment is needed to solve the above problems.

[0006] Preferably, the buoyancy assembly includes a side piece fixed to one side of the sleeve, and a float is fixed on the side piece.
