DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] like Figure 1-6As shown, the utility model provides a pyrolysis treatment and recycling device for composite materials of retired wind turbine nacelle covers, comprising a treatment box 1, a purification box 6 is provided at the rear side of the treatment box 1, pure water for dust removal is filled in the purification box 6, a sleeve 5 is fixedly provided at the top of the purification box 6, a motor 10 is fixedly provided at the top of the sleeve 5, and an exhaust pipe 4 connected to the sleeve 5 is fixedly provided at the rear side of the treatment box 1;
[0027] A partition assembly 11 is provided inside the purification box 6, and the partition assembly 11 includes a central tube 1101 provided inside the purification box 6, an air guide hole 1102 is provided on one side of the central tube 1101, the top and bottom ends of the central tube 1101 are connected to the inner wall of the purification box 6, and partitions 1103 are fixedly provided on both the front and rear sides of the central tube 1101, and a sealing strip 1104 in contact with the inner wall of the purification box 6 is fixedly provided on the outer end of the partition 1103;
[0028] A connecting pipe 12 is fixedly provided at the top of the central tube 1101 . The top of the connecting pipe 12 extends to the top of the sleeve 5 and is fixedly connected to the output shaft of the motor 10 . A connecting hole 13 is opened at the outer end of the connecting pipe 12 . The connecting hole 13 is located inside the sleeve 5 .
[0029] When the retired wind turbine cabin cover is subjected to pyrolysis treatment, since the wind turbine cabin cover is made of glass fiber composite material, it will crack and produce flue gas under high temperature. The flue gas enters the interior of the sleeve 5 along the exhaust pipe 4, and then enters the connecting pipe 12 through the connecting hole 13, enters the central tube 1101 through the connecting pipe 12, and finally is discharged into the water through the air guide hole 1102. After the flue gas enters the water, the dust and impurities therein will remain in the water. When the dust and impurities accumulate to a certain extent, they need to be cleaned. At this time, the motor 10 is turned on, and the connecting pipe 12 is driven by the motor 10 to drive the partition assembly 11 to rotate as a whole. When the two partitions 1103 are rotated to be perpendicular to the front wall and the rear wall of the purification box 6 respectively, the entire partition assembly 11 will purify the moisture inside the purification box 6. The partition 1102 is divided into two parts which are not connected to each other, and the air guide hole 1102 is located in one part of the water. This part of the water continues to perform dust removal work, and the other part of the water can be left still. After a period of sedimentation, the water and sediment are separated, and new water is added after the sediment is cleaned. Then the partition component 11 is rotated again to make the two parts of water communicate again. Since one part of the water has been cleaned and replaced, the impurity concentration inside the entire purification box 6 will be greatly reduced. The above operation can be repeated, and half of the water and impurities in the purification box 6 are cleaned and replaced each time to gradually reduce the concentration of impurities. This cleaning method can not affect the dust removal work, so that the dust removal and the cleaning of impurities in the water can be carried out simultaneously to avoid interfering with the efficiency of dust removal.
[0030] This cleaning method can greatly reduce the content of impurities in the water and prevent it from exceeding the standard, but it cannot completely and thoroughly remove the impurities.
[0031] To clean the deposited impurities, the purification box 6 needs to be opened, such as Figure 1 , 3 As shown in , 4 and 6 , detachable side panels 8 are installed on both sides of the purification box 6 by bolts. After opening the side panels 8, impurities inside the purification box 6 can be cleaned. Two exhaust holes 7 are opened on the top of the purification box 6. The two exhaust holes 7 are respectively located on both sides of the partition component 11, and the smoke after dust removal is discharged through the exhaust holes 7.
[0032] Two pumping assemblies 9 are provided inside the purification box 6. The two pumping assemblies 9 are respectively located on both sides of the partition assembly 11. The pumping assembly 9 includes a cannula 902. A floating ball 903 is fixedly provided at the outer end of the cannula 902. Under the action of the floating ball 903, the cannula 902 floats on the water surface.
[0033] A hose 901 is fixedly provided at the top of the cannula 902 . The top of the hose 901 extends to the top of the purification box 6 . A valve is fixedly provided on the hose 901 .
[0034] During the dust removal process, the smoke after dust removal is finally discharged to the outside through the exhaust hole 7. When cleaning dust and impurities, a part of the water isolated will be left to stand, and the dust and impurities will settle at the bottom of the purification box 6, thereby producing sediment. At this time, open the valve on the hose 901, insert the bottom end of the cannula 902 into the water and float on the water surface under the buoyancy of the float 903. The upper water can be gradually pumped out through the hose 901. After pumping, open the side panel 8 on the corresponding side to clean the remaining sediment. After cleaning, close the side panel 8 and inject new water into the purification box 6 again through the pumping assembly 9.
[0035] The wind turbine nacelle cover is pyrolyzed in the treatment box 1, such as Figure 1 , 2 As shown, a closing plate 2 is provided on the front side of the processing box 1 by means of bolts, and a supporting net 14 is fixedly provided on the inner wall of the processing box 1 .
[0036] Heating plates 15 are fixedly disposed on the inner walls of both sides of the processing box 1 , and the heating plates 15 are located on the top of the supporting net 14 .
[0037] An air intake box 3 is fixedly provided at the top of the processing box 1, an air intake pipe with a one-way valve is fixedly provided at the top of the air intake box 3, and a plurality of nozzles 16 extending into the interior of the processing box 1 are fixedly provided at the bottom of the air intake box 3, so as to input high-temperature nitrogen into the interior of the processing box 1 for protective heating.
[0038] The wind turbine nacelle cover to be processed after retirement is placed on the top of the support net 14. After the processing box 1 is closed by the closing plate 2, the inside of the processing box 1 is heated to a high temperature state of more than 600°C by using the heating plate 15. At the same time, high-temperature nitrogen is introduced into the air inlet box 3 and then injected into the processing box 1 through the nozzle 16. Nitrogen has a certain inertness and can prevent the oxygen in the air from reacting with the cracked gas during the pyrolysis treatment. The cracked ash in the wind turbine nacelle cover will fall through the support net 14, and the uncracked part will continue to remain on the top of the support net 14. The generated flue gas will flow into the purification box 6 through the exhaust pipe 4.
[0039] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
