[0014] One embodiment of this application provides an oil extraction device for industrial oily wastewater, such as... Figure 1 As shown, it includes: a drug mixing unit 1, a heating reaction unit 2, and a filter 3. The drug mixing unit 1 includes a drug mixing vessel 11, on which a first stirring motor 12 is installed. A first stirring paddle 13 is installed on the movable end of the first stirring motor 12 and is located inside the drug mixing vessel 11. The inlet of the drug mixing vessel 11 is located at the top of the drug mixing vessel 11, and the outlet of the drug mixing vessel 11 is located at the bottom of the drug mixing vessel 11. The heating reaction unit 2 includes a heating reaction vessel 21, on which a second stirring motor 22 is installed. A second stirring paddle 23 is installed on the movable end of the second stirring motor 22, and the second stirring paddle 23 is located inside the heating reaction vessel 21. A heating assembly 24 is installed on the heating reactor 21. The heating part of the heating assembly 24 is located inside the heating reactor 21 to heat the medium inside the heating reactor 21. The feed inlet of the heating reactor 21 is located at the top of the heating reactor 21, and the discharge outlet of the heating reactor 21 is located at the bottom of the heating reactor 21; the feed inlet of the heating reactor 21 is connected to the discharge outlet of the reagent mixing vessel 11. The heating reactor 21 has an air outlet 25 at the top and an air inlet 26 at the bottom. The heating reactor 21 also has a waste discharge port at the bottom, which is only opened when waste is being discharged. The feed inlet of the filter 3 is connected to the discharge outlet of the heating reactor 21. The structure of the filter 3 is existing technology and will not be described in detail here.

[0015] Furthermore, it also includes a first feed pump 4, the outlet of which is connected to the inlet of the reagent mixing vessel 11, and the inlet of the first feed pump 4 is used for the entry of the medium.

[0016] Furthermore, it also includes a second feed pump 5, the inlet of which is connected to the outlet of the reagent mixing vessel 11, and the outlet of which is connected to the inlet of the heating reaction vessel 21.

[0017] Furthermore, it also includes a first discharge pump 6, whose inlet is connected to the outlet of the heated reactor 21, and whose outlet is connected to the inlet of the filter 3. When the oily wastewater reaches the preset treatment capacity, the first feed pump 4, the second feed pump 5, and the first discharge pump 6 are shut down. After each reaction is completed, the corresponding pump is turned on. This is prior art and will not be described in detail here.

[0018] It should be noted that the proportions of reagents used in the extraction of oil from industrial oily wastewater are all existing technologies. The focus of this application is on how to apply the device to the extraction of oil from industrial oily wastewater.

[0019] In use, oily wastewater is collected into a reagent mixing vessel via the first feed pump. Neutralizing acid is added to adjust the pH of the wastewater to approximately 2-6. The first stirring paddle in the reagent mixing vessel is used to fully mix the neutralizing acid and wastewater, ensuring that the pH of the wastewater is adjusted to the required level. After the pH of the wastewater is adjusted to 2-6, the mixed acid-added wastewater is pumped into a heated reactor via the second feed pump for demulsification. After the mixed acid-added wastewater is pumped into the heated reactor, the liquid is heated to 60-90 degrees Celsius, and a demulsifier is added to demulsify the emulsified oil. The demulsifier breaks the surface tension of the oil-in-water mixture, causing the oil molecules to detach from the oil and float to the surface. Air is blown from the bottom of the heated reactor to accelerate the demulsification reaction and speed up the floating of the oil molecules. After the demulsification reaction is completed, the oil is discharged from the bottom of the heated reactor to a hazardous waste container for outsourced treatment. After demulsification, the oil floats on the top layer. After the reaction waste liquid is discharged, the demulsified oil is pumped through the first discharge pump into the filter for filtration of moisture, acidity, and impurities. The filter has dehydration, decolorization, and deacidification functions to ensure that the cleanliness and water content of the filtered oil fully meet the requirements for qualified oil products.

[0020] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
