Description

Technical Field

[0001] The utility model relates to the field of equipment related to anaerobic reactors, in particular to a secondary separation and reflux device for anaerobic reactors. Background Art

[0002] Anaerobic reactors are a highly efficient biofilm treatment method. They utilize large surface areas such as sand as a carrier. Anaerobic microorganisms form a membrane attached to the surface of the sand or other carrier, flowing through the wastewater. The microorganisms come into contact with organic matter in the wastewater, adsorbing and decomposing it, thereby achieving the desired treatment. During the anaerobic reaction, the microorganisms decompose the organic matter to produce methane, carbon dioxide, and new cellular substances.

[0003] The existing anaerobic reactor has only one separation and reflux device, but the gas after separation and reflux still contains liquid water droplets and steam, making the collected gas not pure enough and requiring secondary treatment, which increases production costs.

[0029] Working principle: There is liquid that has not been discharged after separation in the middle of the spherical tube 3. Open the solenoid valve on the first oblique tube 2, and the mixed gas enters the lower end of the spherical tube 3 from the first oblique tube 2. The liquid and steam merge into the liquid, and the other gases and steam enter the inside of the first condenser tube 5. The external water pump injects cold water into the spiral condenser tube 10, the first collecting funnel 12 and the second collecting funnel 13 through the water inlet pipe, and finally flows out of the spiral condenser tube 10, the first collecting funnel 12 and the second collecting funnel 13 from the water outlet pipe to circulate the cold water, so as to avoid the cold water inside the spiral condenser tube 10, the first collecting funnel 12 and the second collecting funnel 13 becoming hot after absorbing heat for a long time.

The liquid droplets on the surface of the second collecting funnel 13 fall into the middle of the first collecting funnel 12 and fall into the middle of the spherical tube 3 from the water flow holes. The gas will flow upward through the air holes on the first and second collecting funnels 12 and 13, and finally pass through the water filter plate 11, so that the small water droplets brought out by the gas are separated by the water filter plate 11, gathered into large water droplets on the surface of the water filter plate 11, and fall into the middle of the spherical tube 3. The gas enters the middle of the outlet pipe 9 from the second connecting pipe 8 and flows into the collection device. When the liquid in the middle of the spherical tube 3 exceeds a certain volume, the solenoid valve on the second oblique pipe 4 is opened to allow part of the liquid to flow back to the anaerobic reactor along the second oblique pipe 4. Then the solenoid valve is closed to allow the device to continue working.
