[0027] Embodiment

[0028] As Figures 1 to 2 shown,

[0029] Prior art reference document 1, as Figure 1 , the organic waste liquid is uniformly collected in the waste liquid tank 1 through the liquid inlet pipeline, and then the waste gas at the top inside the waste liquid tank 1 is collected and discharged through the exhaust pipeline 3 on one side.

[0030] As Figure 2 , an organic waste liquid recovery system includes a waste liquid tank 1, a liquid inlet pipeline 2 and an exhaust pipeline 3. The liquid inlet pipeline 2 is installed at a position near the top on the left side of the waste liquid tank 1, and the exhaust pipeline 3 is installed on one side of the top of the waste liquid tank 1.

[0031] An aeration device 8 is installed inside the bottom of the waste liquid tank 1. The intake main pipeline 5 of the compressed air storage tank 4 is connected to the aeration device 8 through the lower intake branch pipeline 6. The exhaust pipeline 3 is sequentially connected to the collection tank 15 through the gas-liquid separator 12 and the cooler 14. The intake main pipeline 5 is connected to a position near the top on the right side of the waste liquid tank 1 through the upper intake branch pipeline 7. The gas-liquid separator 12 is connected to the intake main pipeline 5 through the gas return pipeline 13.

[0032] A liquid discharge pipeline 9 is installed at the bottom of the waste liquid tank 1. The liquid discharge pipeline 9 is connected to the liquid outlet pipeline 10, and the liquid discharge pipeline 9 is connected to the liquid inlet pipeline 2 through the liquid return pipeline 11.

[0033] Among them,

[0034] A dryer is installed on the gas return pipeline 13.

[0035] The gas-liquid separator 12 is a membrane separator, and the cooler 14 is a condenser.

[0036] The aeration device 8 is an aeration pipe.

[0037] A brief description of the working principle of the present utility model is as follows:

[0038] The organic waste liquid is collected in the waste liquid tank 1 through the liquid inlet pipe 2. Then, the compressed air in the compressed air storage tank 4 enters the aeration device 8. The compressed air is nitrogen. The organic waste gas in the organic waste liquid is carried out by the flow of nitrogen. Then, driven by the nitrogen in the upper intake branch pipe 7, the organic waste gas is accelerated into the gas-liquid separator 12. After passing through the gas-liquid separator 12, the organic waste gas is cooled to an organic waste liquid in the cooler 14 and collected in the collection tank 15, effectively purifying the organic waste liquid in the organic waste gas. The nitrogen that does not pass through in the gas-liquid separator 12 flows back to the intake main pipe 5 through the gas return pipe 13 for recycling.
