[0033] It should be understood that the order of execution of the steps in the following embodiments does not imply a precedence of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0034] An embodiment of the present invention provides a method for recycling renewable resources, which comprises the following steps:

[0035] Step 1: Pyrolysis the pre-treated waste tires through a pyrolysis unit to produce pyrolysis carbon black and hot oil and gas;

[0036] Step 2: Cooling and separating the hot oil and gas to obtain pyrolysis oil and non-condensable raw coal gas, and recovering the pyrolysis oil; wherein the cooling and separation operation is performed by a cooling unit;

[0037] Step 3: subjecting the non-condensable raw coal gas in step 2 to high-temperature combustion treatment, and conveying the generated tail gas to a deep processing unit;

[0038] Step 4: deep processing the pyrolysis carbon black in step 1 to obtain a carbon black particle product, and the carbon black particle product is dried by the tail gas and then discharged as waste gas.

[0039] Specifically, you can use the attached Figure 1The recycling system comprises a pyrolysis unit 100, a cooling unit 200, a CHP power generation unit 300 and a deep processing unit 400; the pyrolysis unit 100 is used for pre-treating waste tires by pyrolysis to produce pyrolysis carbon black and hot oil and gas, and the pyrolysis carbon black is transmitted to the deep processing unit 400, and the hot oil and gas is transmitted to the cooling unit 200; the cooling unit 200 is used for cooling and separating the hot oil and gas to produce pyrolysis oil and non-condensable raw gas, recovering the pyrolysis oil, and transmitting the non-condensable raw gas to the CHP power generation unit 300; the CHP power generation unit 300 is used for burning the non-condensable raw gas at high temperature to generate electricity, and transmitting the generated tail gas to the deep processing unit 400; the deep processing unit 400 is used for processing the pyrolysis carbon black to obtain a carbon black particle product, and the carbon black particle product is dried by the tail gas and then discharged as waste gas.

[0040] The renewable resource recovery process of the present invention forms a complete industrial recovery system, using the pyrolysis unit 100 to crack the waste tires, the cooling unit 200 can process the hot oil and gas generated by the cracking, and the deep processing unit 400 can process the carbon black generated by the cracking, so that the pyrolysis oil, carbon black and other by-products in the waste tires can be recovered. Among them, in order to further improve the resource utilization rate, the non-condensable raw gas obtained after cooling and separation is burned at high temperature by the CHP power generation unit 300, which can prevent the non-condensable raw gas from being directly discharged to cause safety problems and pollution on the one hand, and realize resource reuse on the other hand. The CHP power generation unit 300 uses the non-condensable raw gas to generate electricity, which can power the renewable resource recovery equipment of the present invention, and achieve the purpose of energy saving and emission reduction. At the same time, the tail gas generated after the CHP power generation unit 300 burns the non-condensable raw gas at high temperature is reused to dry the carbon black particle product obtained by the deep processing unit 400, which further improves the resource recycling rate and also improves the quality of the carbon black particle product. The present invention realizes the industrial production of waste tire recycling, effectively improves the efficiency of waste tire recycling, and has a high resource utilization rate.

[0041] It is understandable that the pyrolysis oil generated by the cooling module 200 is collected and recycled by the collection unit 500 .

[0042] Furthermore, in some embodiments, the deep processing comprises the following steps:

[0043] Step 1: activating the pyrolysis carbon black by an activation furnace;

[0044] Step 2: Processing the activated pyrolysis carbon black into granules through a granulator;

[0045] Step 3: Use the tail gas in step 3 to dry the processed carbon black pellets through a drum drying furnace; see the attached Figure 1The deep processing unit 400 includes an activation furnace 430, a granulator 440, and a drum drying furnace 450; wherein the activation furnace 430 is used to activate the pyrolysis carbon black; the granulator 440 processes the activated pyrolysis carbon black into granules; and the drum drying furnace 450 utilizes the tail gas to perform hot air drying on the processed carbon black granule product.

[0046] In some embodiments, see Appendix Figure 2 The deep processing unit 400 also includes a magnetic separator 410, a grinder 420, and a screening machine 460. The cracked carbon black delivered by the pyrolysis unit 100 must first pass through the magnetic separator 410 to further screen out metal objects such as steel wire, and then be delivered to the grinder 420 for grinding. The ground carbon black material is delivered to the activation furnace 430, a coupling agent and water are added, and activated at a temperature of 80°C to 100°C. The activated carbon black material is delivered to the granulator 440, and an adhesive is added to the carbon black material to form carbon black particles. The carbon black particles are then delivered to the drum drying furnace 450, and the exhaust gas is used to perform hot air drying on the carbon black particles. The dried carbon black particles are screened out by the screening machine 460 to obtain the finished carbon black particle products.

[0047] Further, in some embodiments, the deep processing also includes gas purification, see the attached Figure 2 The deep processing unit 400 includes a gas purification device 470, and the gas purification operation is performed by the gas purification device 470, which is used to purify the waste gas discharged after drying the carbon black particle product.

[0048] Specifically, the purification process of the gas purification device 470 includes but is not limited to dust removal, denitration, deodorization, removal of non-methane total hydrocarbons, etc. In addition, the purified exhaust gas needs to pass through a chimney before it can be discharged to the outside.

[0049] Further, in some embodiments, the deep processing also includes gas detection, see the attached Figure 2 The deep processing unit 400 includes a gas detection device 490, and the gas detection device 490 is used to detect the exhaust gas purified by the gas purification device 470.

[0050] Understandably, in this embodiment, even if the waste gas has been purified, it still needs to be detected by the gas detection device 490, and can only be controlled for emission after the detection meets the standard. The waste gas emitted by the renewable resource recovery method of the present invention meets the waste gas emission concentration and restrictions in the GB / T326662-2016 standard, DB44 / 27-2001 standard, GB14554-93 standard, and GB18485-2014 standard, protecting the environment while utilizing resources.

[0051] Furthermore, in some embodiments, the deep processing also includes pre-processing, see the attached Figure 2 and attached Figure 3 The deep processing unit 400 includes a pre-processing unit 480, which includes a gravity dehydration tank 1. The air inlet end A1 of the gravity dehydration tank 1 is connected to the gas purification device 470 through a pipeline, the air outlet end A2 of the gravity dehydration tank 1 is connected to the gas detection device 490 through a pipeline, and the liquid discharge end A3 of the gravity dehydration tank 1 is connected to a liquid discharge valve V5 through a pipeline.

[0052] Further, in some embodiments, see the attached Figure 3 The pre-processing unit 480 also includes a water-cooled cooler 2, which is connected between the gravity dehydration tank 1 and the gas detection device 490 through a pipeline, and the air inlet end B1 of the water-cooled cooler 2 is connected to the air outlet end A2 of the gravity dehydration tank 1 through a pipeline, and the air outlet end B4 of the water-cooled cooler 2 is connected to the gas detection device 490 through a pipeline.

[0053] Further, in some embodiments, see the attached Figure 3 The pre-processing unit 480 also includes a mesh filter 3, which is connected between the water-cooled cooler 2 and the gas detection device 490 through a pipeline, the air inlet end C2 of the mesh filter 3 is connected to the air outlet end B4 of the water-cooled cooler 2 through a pipeline, the air outlet end C1 of the mesh filter 3 is connected to the gas detection device 490 through a pipeline, and the filter end C3 of the mesh filter 3 is connected to the filter valve V10 through a pipeline.

[0054] Further, in some embodiments, see the attached Figure 3 The pre-processing unit 480 also includes an activated carbon filter 4, which is connected between the mesh filter 3 and the gas detection device 490 through a pipeline, and the air inlet end D1 of the activated carbon filter 4 is connected to the air outlet end of the mesh filter 3 through a pipeline, and the air outlet end D2 of the activated carbon filter 4 is connected to the gas detection device 490 through a pipeline.

[0055] It should be noted that after the purified waste gas enters the gravity dehydration tank 1, the oil and water carried in the waste gas will remain at the bottom of the gravity dehydration tank 1 due to gravity, and the remaining waste gas will continue to be transported to the water-cooled cooler 2. The liquid retained in the gravity dehydration tank 1 can flow out through the drain end A3 at the bottom of the tank, and can be discharged by opening the drain valve V5.

[0056] See attached Figure 3In the water-cooled cooler 2, the cooling water pipeline of the water-cooled cooler 2 is connected to the water inlet B3 and the water outlet B2. Water is taken in through the water inlet B3 of the water-cooled cooler 2, and a water inlet valve V8 is arranged on the pipeline connected to the water inlet. Water is discharged through the water outlet B2 of the water-cooled cooler 2. Exhaust gas can pass through the cooling water pipeline and the inner wall of the water-cooled cooler 2. The air inlet end B1 of the water-cooled cooler 2 is at the top, and the air outlet end B4 of the water-cooled cooler 2 is at the bottom. The cooling water flows from bottom to top along the cooling water pipeline. The cooling water pipeline is arranged with multiple tube bends, which increases the contact area between the exhaust gas and the cooling water pipeline, thereby effectively taking away the heat of the exhaust gas flowing from top to bottom, so that the remaining gas oil mist in the exhaust gas is converted into liquid oil, and the liquid oil and the cooled exhaust gas are transported from the air outlet end B4 to the mesh filter 3.

[0057] See attached Figure 3 In the mesh filter 3, the air inlet end C2 of the mesh filter 3 is at the bottom, the filtering end C3 of the mesh filter 3 is arranged at the bottom, the filtering component of the mesh filter 3 is arranged at the middle and upper part, and the air outlet end C1 of the mesh filter 3 is arranged at the top. The exhaust gas is discharged after passing through the filtering component from bottom to top, and is transported to the activated carbon filter 4 after removing the liquid oil and some impurities. The liquid oil remains at the bottom of the mesh filter 3, and the liquid oil can be discharged after opening the filter valve V10.

[0058] See attached Figure 3 In the activated carbon filter 4, the air inlet end D1 of the activated carbon filter 4 is located at the top, and the air outlet end D2 of the activated carbon filter 4 is located at the bottom. The exhaust gas passes through the activated carbon filter 4 from top to bottom, further adsorbs impurities, and then is delivered to the gas detection device 490. Understandably, the gas detection device 490 can use an LRGA gas analyzer. The present invention uses multiple filtrations to pre-treat the exhaust gas, effectively improving the gas purity of the exhaust gas detected by the gas detection device 490, thereby effectively ensuring the accuracy of the gas detection results, and is useful for judging whether the exhaust gas emissions meet the standards.

[0059] Furthermore, in some embodiments, the pre-processing unit 480 includes a pipeline sampling end, the air inlet end of the gravity dehydration tank 1 is connected to the pipeline sampling end through a pipeline, and an air inlet valve is arranged between the air inlet end of the gravity dehydration tank 1 and the pipeline sampling end through the pipeline.
