[0036] Please refer to Figure 1 together. Now, the phenol water filtration system provided by the present utility model will be described. The phenol water filtration system includes a phenol water tank 10, a filter 20, a mixer 30, a heating device 54, and a phenol water heater 50. The phenol water tank 10 includes independent first, second, and third tank compartments 11, 12, and 13; the filter 20 has a first water inlet pipe 21 communicating with the first tank compartment 11 and a first water outlet pipe 22 communicating with the second tank compartment 12; the mixer 30 has a second water inlet pipe 31 communicating with the second tank compartment 12 and a second water outlet pipe 32 communicating with the third tank compartment 13; the chemical dosing device 40 has a chemical dosing pipe 41 communicating with the second water inlet pipe 31; the phenol water heater 50 has a third water inlet pipe 51 communicating with the third tank compartment 13 and a third water outlet pipe 52 communicating with the outside. The phenol water heater 50 is used to generate steam for use as a gasifying agent.

[0037] Among them, power pumps 60 are provided on the first water inlet pipe 21, the second water inlet pipe 31, and the third water inlet pipe 51.

[0038] Specifically, in order to meet the phenol water treatment requirements, the volumes of the first tank compartment 11, the second tank compartment 12, and the third tank compartment 13 increase in sequence.

[0039] The phenolic water filtration system provided in this embodiment, compared with the prior art, stores phenolic water normally in the first tank 11. After the water and clear oil in the first tank 11 are separated, the power pump 60 on the first water inlet pipe 21 is turned on to pump the water in the first tank 11 into the filter 20. After filtration, it flows into the second tank 12 through the first water outlet pipe 22. The phenolic water in the second tank 12 is pumped into the mixer 30 by the power pump 60 on the second water inlet pipe 31. The dosing device 40 and the phenolic water in the second tank 12 enter the mixer 30 together to adjust the pH of the phenolic water. The phenolic water treated in the mixer 30 enters the third tank 13 through the second water outlet pipe 32. The power pump 60 on the third water inlet pipe 51 is turned on to pump the phenolic water in the third tank 13 into the phenolic water heater 50. The steam generated by the phenolic water heater 50 is used as a gasifying agent, and the remaining liquid can be directly discharged. The phenolic water filtration system of the present utility model filters wastewater containing phenolic compounds through the filter 20, controls the pH adjustment of the phenolic water through the mixer 30, and can adjust the working process of the filter 20 in combination with the treatment result of the mixer 30. Moreover, the final phenolic water can still be used to generate a gasifying agent, which is energy-saving and environmentally friendly; it is divided into three treatment processes, the treatment process is simple, convenient to operate, the control process is simple, and it has the effect of reducing energy consumption.

[0040] In some embodiments, an improved implementation manner of the second water inlet pipe 31 can be adopted as Figure 1 shown in the structure. Refer to Figure 1 , a branch pipe 33 is provided on the second water inlet pipe 31. The branch pipe 33 is communicated with the filter 20 and is used for backwashing the filter 20. The filter 20 also has a first drain pipe 23 communicated with the first tank 11. In order to ensure the filtering effect of the filter 20, the filter 20 needs to be cleaned after being used for a period of time. If an external water source is used for cleaning, it not only wastes water resources but also cannot directly discharge the cleaning water; by providing a branch pipe 33 at the second water inlet pipe 31, the branch pipe 33 can be opened when the filter 20 needs to be backwashed. When the power pump 60 on the second water inlet pipe 31 pumps the phenolic water in the second tank 12, the phenolic water will enter the filter 20 through the branch pipe 33 for backwashing. The cleaning water after backwashing flows back into the first tank 11 through the first drain pipe 23 and can be treated by the filter 20.

[0041] The structure of this embodiment uses the phenolic water in the second tank 12 to backwash the filter 20, which can not only ensure the filtering effect of the filter 20 but also save water resources and reduce production costs.

[0042] In some embodiments, an improved implementation manner of the above-mentioned mixer 30 can be adopted as Figure 1 shown in the structure. Refer to Figure 1, the mixer 30 has a second drain pipe 34 communicating with the first drain pipe 23, and on-off valves 80 are provided on both the first drain pipe 23 and the second drain pipe 34. The liquid retained in the mixer 30 can flow back to the first tank 11 through the second drain pipe 34, avoiding affecting the pH adjustment of the phenolic water.

[0043] In some embodiments, an improved implementation of the above dosing device 40 can adopt a structure as Figure 1 shown. Refer to Figure 1 , the dosing device 40 further includes a dosing bucket 42 communicating with the dosing pipe 41, and a flow meter 43 is provided at the outlet of the dosing bucket 42. When dosing, the amount of medicine flowing out will be displayed in the flow meter 43, so as to facilitate obtaining the total amount of medicine added, realizing precise control of the dosing amount, ensuring the pH adjustment effect of the phenolic water while not wasting.

[0044] In some embodiments, an improved implementation of the above first water inlet pipe 21, second water inlet pipe 31, and third water inlet pipe 51 can adopt a structure as Figure 1 shown.

[0045] Specifically, a regulating valve 71 is provided on the return pipe 70.

[0046] When the first water inlet pipe 21, second water inlet pipe 31, and third water inlet pipe 51 are in use, some phenolic water will be retained inside. To ensure the treatment effect of the phenolic water, the regulating valve 71 can be periodically opened to make the phenolic water in each water inlet pipe flow back to the corresponding tank.

[0047] In some embodiments, an improved implementation of the above phenolic water heater 50 can adopt a structure as Figure 1 shown. Refer to Figure 1 , the phenolic water heater 50 also has a sewage discharge pipe 53, and the sewage discharge pipe 53 communicates with the first tank 11. The sewage in the phenolic water heater 50 is discharged into the first tank 11, and can be processed again, and will not pollute the environment, improving the processing efficiency.

[0048] In some embodiments, a specific implementation of the above phenolic water heater 50 can adopt a structure as Figure 1 shown. Refer to Figure 1, the phenol water heater 50 includes a heating device 54 and a steam-water separation device 55. The steam-water separation device 55 is used to separate steam for use as a gasifying agent. A blowdown pipe 53 is provided on the heating device 54, and a third water outlet pipe 52 is provided on the steam-water separation device 55. The phenol water in the third water inlet pipe 51 flows into the heating device 54 through the steam-water separation device 55. After being heated by the heating device 54, it flows back to the steam-water separation device 55. After the steam-water separation device 55 separates steam and water, the water is directly discharged, and the steam is used as a gasifying agent, which can realize the reuse of steam, save energy and protect the environment.

[0049] In some embodiments, a specific implementation manner of the above-mentioned first water inlet pipe 21, second water inlet pipe 31, and third water inlet pipe 51 can adopt the structure as Figure 1 shown. Refer to Figure 1 , check valves 90 are provided at the water inlet ends of the first water inlet pipe 21, second water inlet pipe 31, and third water inlet pipe 51. The check valves 90 are immersed in the corresponding pool bins, which can make the liquid in the corresponding water inlet pipes flow unidirectionally, thus ensuring the normal operation of the power pump 60, avoiding the backflow of phenol water, and prolonging the service life of the power pump 60.

[0050] In some embodiments, an improved implementation manner of the above-mentioned phenol water filtration system can adopt the structure as Figure 1 shown. Refer to Figure 1 , the phenol water filtration system further includes an automatic control unit.

The readings of the temperature sensor, pressure sensor, flow sensor, and PH sensor can all be transmitted to the controller and displayed on the display screen. By receiving the detection data through the controller, the actual working state can be adjusted according to the displayed data. For example, the chemical dosing amount can be adjusted according to the value of the PH sensor, realizing the overall automatic control.
