A waste liquid inlet pipe 2 is fixed on the top of one side of the boiling chamber 1, and a lifting pump 3 is installed on the waste liquid inlet pipe 2. The bottom end of the waste liquid inlet pipe 2 is connected and fixed to one side of the top of the pretreatment box 4, and the bottom of the pretreatment box 4 A waste pipe 5 is fixed at the end, a raw liquid pipe 6 is installed on the top of the other side of the pretreatment box 4, a servo motor 7 is fixed to the center of the top surface of the pretreatment box 4, a stirring fan blade 8 is fixed to the end of the output shaft of the servo motor 7, the bottom of the other side of the boiling chamber 1 is connected to the liquid filter chamber 10, a transfer pipe 11 is fixed to the top of the other side of the boiling chamber 1, the top of the transfer pipe 11 is connected to one side of the substrate 12, an exhaust pipe 13 is fixed on the other side of the substrate 12, a partition plate 14 is fixed on the top surface of the exhaust pipe 13, an air filter box 15 is installed on the top of the exhaust pipe 13, and a filter material 16 is arranged in the air filter box 15.

[0021] The front view shape of the waste liquid inlet pipe 2 in this example is "L"-shaped, and the bottom end of the waste liquid inlet pipe 2 is higher than the horizontal plane where the center of the pretreatment box 4 is located. The above structural design facilitates the waste liquid inlet pipe 2 to effectively transfer the upper clear liquid after flocculation and sedimentation to remove impurities.

[0022] A dosing pipe 9 is installed on the top of the pretreatment box 4. The diameter of the dosing pipe 9 is not less than the radius of the raw liquid pipe 6. The above structural design can conveniently add the flocculating agent and ensure that the flocculating agent can be added in large quantities at a time.

[0023] The dosing pipe 9 is arranged directly above the stirring blade 8 , and the horizontal plane where the center of the stirring blade 8 is located is not higher than the horizontal plane where the center of the pretreatment box 4 is located. The above structural design ensures that the added flocculating agent can be fully mixed with the waste liquid under the stirring of the stirring blade 8 .

The above structural design ensures that the gas can have a large-area and long-term contact with the filter material 16 in the air filter box 15, thereby ensuring the filtering effect on the gas.

[0026] Working principle: When using this device, the high-salt and high-organic waste liquid is passed through Figure 2The raw liquid pipe 6 in the pretreatment box 4 is used to add a sufficient amount of flocculating agent through the dosing pipe 9, and the servo motor 7 is started to drive the stirring blade 8 to rotate stably to fully mix the agent with the waste liquid. Then the servo motor 7 is turned off, the raw liquid is allowed to settle statically, and the lifting pump 3 installed on the waste liquid inlet pipe 2 is started to pump the upper clear liquid into the boiling chamber 1, and the flocculated impurities are discharged through the waste discharge pipe 5;

[0027] Then the boiling chamber 1 is started for normal concentration, and the concentrated liquid is passed into the liquid filter chamber 10 for filtration. The boiling chamber 1 and the liquid filter chamber 10 have the same structure as the existing device, which is the existing mature technology and is well known to those skilled in the art, and will not be described in detail here;

The filter material 16 filters the gas with high throughput and high efficiency. It is only necessary to remove the air filter box 15 regularly to clean or replace the filter material 16. This is the working principle of the high-salt and high-organic waste liquid concentration equipment.
