Technical Field

[0001] This application relates to the technical field of contaminated soil treatment, and specifically to a pollutant treatment system for generating multiple products. Background Art

[0002] The pollutants to be treated mainly include tank cleaning sludge, sludge generated during the mining and transportation of sludge, and sludge-contaminated soil. The tank cleaning sludge has a high oil content and few impurities. Therefore, it directly enters the conditioning tank for treatment. The sludge on the ground and the sludge-contaminated soil have more impurities.

[0003] Based on the above description, sorting is carried out first to screen out the impurities in the sludge. The bricks, stones, etc. in the selected inorganic impurities are broken and made into non-fired bricks. The sorted plastic organic impurities are processed by a granulator to produce plastic particles. The sorted sludge is heated with hot water to become a fluidized state and enters the conditioning tank. During the conditioning process, the sludge is heated, dosed, and stirred to fully separate the oil and the sludge.

[0004] During the pollutant treatment process, during the sludge treatment process, the oil separates and floats to the upper layer. At this time, the medicine is added by the dropping method, resulting in insufficient mixing of the oil and the sludge and an extended conditioning time. For this reason, a pollutant treatment system for generating multiple products is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0022] Please refer to Figures 1-4 , a pollutant treatment system for generating multiple products in this embodiment, including a conditioning tank 1 for storing pollutants and a stirring structure installed on the conditioning tank 1.

[0023] In this embodiment, the stirring structure includes a stirring motor 3 as a power source, a stirring shaft 5 connected to the power end of the stirring motor 3, and a blade structure located outside the stirring shaft 5.

[0024] Preferably, the blade structure includes a connecting sleeve 6 fixedly installed outside the stirring shaft 5, an extension rod 7 fixedly installed outside the connecting sleeve 6, and a blade 8 fixedly connected to the end of the extension rod 7.

[0025] In specific implementation, the connecting sleeve 6, the extension rod 7, and the blade 8 of the blade structure are driven to rotate by the stirring motor 3, so as to realize the stirring of the pollutants in the conditioning tank 1.

[0026] It should be noted that an extension platform 2 is also fixedly installed on the top of the conditioning tank 1. The outside of the extension platform 2 is supported by diagonal braces. At the same time, the stirring motor 3 is fixedly connected to the extension platform 2, and the installation of the stirring motor 3 can be facilitated through the extension platform 2.

[0027] In this embodiment, a medicine adding member for connecting the stirring shaft 5 is also provided on the power end of the stirring motor 3. The medicine adding member includes a connecting seat 4 fixedly installed on the power end of the stirring motor 3 and a medicine tank 12 fixedly connected to the connecting seat 4.

[0028] In this embodiment, a liquid distributor 14 is fixedly installed on the inner wall of the medicine tank 12. One end of the stirring shaft 5 is fixedly connected to the liquid distributor 14. The liquid distributor 14 is a cylindrical barrel with an open top. The stirring shaft 5 is fixedly connected to the liquid distributor 14, and the liquid distributor 14 and the stirring shaft 5 are interconnected, so that the added medicine in the medicine tank 12 can be sent into the stirring shaft 5 from the liquid distributor 14.

[0029] It should be noted that a liquid outlet 9 for discharging the medicine is also provided on the outer part of the stirring shaft 5, and an extrusion hole 11 communicating with the connecting sleeve 6 is also provided on the outer part of the blade 8. The extrusion hole 11 and the liquid outlet 9 are interconnected, so that the medicine in the medicine tank 12 can be sent into the medicine from the bottom of the conditioning tank 1 and stirred.

[0030] It is further supplemented that a plugging member 10 for closing the lower end of the stirring shaft 5 is also fixedly installed at the bottom of the stirring shaft 5. By opening the plugging member 10, it is convenient to clean the inside of the stirring shaft 5.

[0031] In this embodiment, an installation ring 13 is also fixedly installed outside the medicine tank 12 for providing external protection. A threaded rod 17 extending to the upper end of the liquid distributor 14 is rotatably installed in the medicine tank 12. An extrusion block 20 sliding relative to the medicine tank 12 is threadedly connected to the outside of the threaded rod 17. By rotating the threaded rod 17, the two extrusion blocks 20 can extrude the medicine in the medicine tank 12.

[0032] Preferably, the outside of the threaded rod 17 has two sections of opposite threads, and at this time the two extrusion blocks 20 move in opposite directions.

[0033] In this embodiment, a driving motor 15 is also fixedly installed outside the medicine tank 12. A first pulley 16 for traction is fixedly connected to the power end of the driving motor 15. One end of the threaded rod 17 penetrates and extends to the outside of the medicine tank 12. A second pulley 18 is fixedly installed at the end of the threaded rod 17 extending to the outside of the medicine tank 12. A transmission belt 19 is sleeved between the first pulley 16 and the second pulley 18.

[0034] In specific implementation, by driving the first pulley 16 to rotate through the driving motor 15, the second pulley 18 can be driven to rotate through the first pulley 16, so as to realize the traction of the threaded rod 17.

[0035] During the heating and medicine addition conditioning process, the waste gas generated during the conditioning process enters the flue gas treatment system for treatment. After conditioning and centrifugation, the solid phase contains less than 10% oil. The conditioned oily sludge enters the three-phase centrifuge to separate the oil, water, and solid slag into three phases. The separated oil enters the storage tank for storage, and is further purified to produce refined oil subsequently;

[0036] The separated water first undergoes primary sedimentation and then is treated by air flotation. After treatment, it is recycled as purified water and can be stored in a hot water tank for use. The separated solid waste is sent to a thermal desorption device by a scraper conveyor. The organic waste gas generated by thermal desorption is adsorbed by activated carbon, dust is removed through a bag filter, and water and alkali solution are added through a spray tower to reduce the content of nitrogen oxides and sulfur oxides in it. Finally, it is discharged up to standard. The oil content after thermal desorption is less than 1%. The final waste residue generated by the treatment is transported by a shaftless screw to prepare non-burned bricks. The waste gas generated enters the flue gas treatment system and is discharged up to standard after treatment.

[0037] The working principle of the above embodiment is as follows:

[0038] By controlling the stirring motor 3 located on the extension table 2, the connecting seat 4 fixed to the power end of the stirring motor 3 drives the medicine tank 12 and the stirring shaft 5 to rotate. At this time, the blades 8 outside the stirring shaft 5 rotate with the stirring shaft 5 to stir the oil contaminants. At the same time, the driving motor 15 is controlled, and the driving motor 15 drives the first pulley 16 on the power end to rotate. The first pulley 16 drives the second pulley 18 to rotate through the transmission belt 19 during rotation. At this time, the second pulley 18 drives the fixedly connected threaded rod 17 to rotate, so that the extrusion block 20 threadedly connected to the threaded rod 17 extrudes the medicine in the medicine tank 12, so that the medicine can be extruded and added through the liquid outlet 9 and the extrusion holes 11 along the direction of the stirring shaft 5.
