Description

Technical Field

[0001] The present invention relates to the field of pyrolysis technology, and in particular to a device and method for pyrolyzing glass fibers of wind turbine blades. Background Art

[0002] The blades of wind turbines are mainly made of materials such as fiberglass and epoxy resin, which have the characteristics of low density, high strength and corrosion resistance. However, this also increases the difficulty of recycling wind turbine blades. The main method of blade recycling is to crush the blades and then heat them indirectly, so that the fine materials reach the pyrolysis temperature and maintain the corresponding temperature for a period of time until the macromolecular substances in the fine materials are cracked.

[0003] For example, Chinese patent CN118027999B discloses a waste fan blade pyrolysis treatment device and pyrolysis method. The device pushes the waste fan blade fragments into a tank by upper and lower layers and differential reverse rotation, uses a vortex heating plate to separate and heat the fine materials, and increases the contact area between the fine materials by stirring.

[0004] However, while the vortex heating plate increases the contact area between the fine material and the heat medium, the vortex heating plate occupies more furnace volume, and the single pyrolysis amount is small, which affects the pyrolysis efficiency; and the fine material accumulates in the heating plate, and the mixed gas produced by the pyrolysis is difficult to discharge in time; at the same time, the turning plate between the vortex heating plates can only turn the fine material in a smaller range at a time, and the turning efficiency is low, and it is difficult to make the fine material and the heating medium contact evenly in time.

[0024] In order to better achieve the purpose of the present invention, the present invention also provides a method for using a wind turbine blade glass fiber pyrolysis device, comprising the following steps:

[0025] Step 1: Ignite the combustion furnace to indirectly heat the pyrolysis furnace; the nitrogen produced by the nitrogen generator is pressurized by the booster pump and then transported to the first heat exchange tube; the flue gas and heat flow generated by the combustion in the combustion furnace are transported to the heat exchange box through the combustion furnace tube, and the residual heat of the flue gas in the heat exchange box is heat exchanged through the first heat exchange tube, thereby heating the nitrogen in the first heat exchange tube; the nitrogen heated in the first heat exchange tube is transported to the feed box through the first delivery tube;

[0026] Step 2: The fine materials crushed by the fan blades are delivered to the feeding box through the feeding pipe, and the heated nitrogen in the first delivery pipe blows the fine materials in the feeding box to the spiral feeding pipe between the combustion furnace and the pyrolysis furnace. The fine materials in the spiral feeding pipe between the combustion furnace and the pyrolysis furnace are preheated for a long time by the heated nitrogen; then the fine materials fall onto the cone panel in the pyrolysis furnace;

[0027] Step 3: The motor drives the cone panel to rotate, and the fine materials on the cone panel are dispersed to the surroundings under the action of centrifugal force. The fine materials fall from the cone panel and move downward along the inner wall of the pyrolysis furnace to accumulate until the fine materials move to the inner bottom of the pyrolysis furnace. The fine materials at the bottom edge of the pyrolysis furnace pass through the lower side of the straight tube and move to the bottom of the spiral blade inside the straight tube;

[0028] Step 4: The rotating shaft then drives the spiral blade, and the spiral blade cooperates with the straight cylinder to drive the fine material upward until the fine material on the spiral blade is separated from the top of the straight cylinder, and then the fine material is separated from the spiral blade outward; thereby driving the fine material in the pyrolysis furnace to circulate from top to bottom and from inside to outside;

[0029] Step 5: The nitrogen heated in the first heat exchange tube is transported to the second heat exchange tube through the second transport pipe. The nitrogen in the second heat exchange tube is heated again between the combustion furnace and the pyrolysis furnace and then transported to the annular tube. The heated nitrogen is transported to multiple vertical tubes through the annular tube and then blown out through the jet holes. The fine material inside the pyrolysis furnace is heated, and the pyrolysis mixed gas generated by the pyrolysis of the fine material is driven to be discharged through the pyrolysis gas pipe.

[0030] Step 6: After the pyrolysis is completed, the push cylinder drives the slide plate to move through the push plate, so that the slide plate no longer blocks the discharge of the solid material after pyrolysis; the solid material after pyrolysis is discharged into the discharge bin through the discharge port, and the push cylinder pushes the solid material through the push plate; the electric push rod drives the bin door to lift through the mounting plate to push out the solid material.

[0031] The present invention has the following beneficial effects:

[0032] 1. The fan blade fine material after crushing is delivered to the spiral material guide assembly, and the fine material is transported to the interior of the pyrolysis furnace through the pneumatic assembly and the spiral material guide assembly; in this process, the temperature of the fine material is quickly increased by the pneumatic assembly and the spiral material guide assembly, so that the temperature of the fine material is quickly increased to the pyrolysis temperature, and the time for the fine material to be increased to the temperature required for pyrolysis is shortened without reducing the volume of the furnace; the pyrolysis furnace can accommodate more fine materials, the single pyrolysis amount is large, and the pyrolysis efficiency of the fine materials is improved;

[0033] 2. The spiral material guide assembly transports the fine material to the dispersion assembly, and the dispersion assembly evenly disperses the fine material to a position near the inner wall of the pyrolysis furnace. The dispersed fine material first contacts the pyrolysis furnace with a higher inner wall temperature, which helps the fine material to heat up, and then flows to the straight cylinder; then the fine material in the middle of the lower side of the pyrolysis furnace is lifted upward by the circulation assembly and dispersed to the inner wall of the pyrolysis furnace, thereby improving the uniformity of the heating of the fine material and making the fine material in the pyrolysis furnace surge from the middle to the outside, which helps the fine material in the pyrolysis furnace to be evenly pyrolyzed, avoids prolonging the pyrolysis time due to the insufficient temperature of the fine material in the middle, and helps to reduce energy consumption. At the same time, the mixed gas generated by the pyrolysis of the fine material is released through the pyrolysis gas pipe in time;

[0034] 3. The waste heat generated by the combustion in the combustion furnace is recovered by the pneumatic component, which saves energy while heating the airflow in the pneumatic component used to transport fine materials to preheat the fine materials; the gas in the pneumatic component is transported to the blowing component, and the gas in the blowing component is heated again by the combustion furnace and evenly blown to the inside of the pyrolysis furnace to heat the fine materials in the middle of the pyrolysis furnace. At the same time, the airflow drives the fine materials to surge, further accelerating the release of the mixed gas produced by pyrolysis through the pyrolysis gas pipe; thereby further improving the pyrolysis efficiency.

[0074] Step 1: Ignite the combustion furnace 2 to indirectly heat the pyrolysis furnace 3; the nitrogen produced by the nitrogen generator 411 is pressurized by the booster pump 412 and then transported to the first heat exchange tube 414; the flue gas and heat flow generated by the combustion in the combustion furnace 2 are transported to the heat exchange box 413 through the combustion furnace tube 21, and the residual heat of the flue gas in the heat exchange box 413 is heat exchanged through the first heat exchange tube 414, thereby heating the nitrogen in the first heat exchange tube 414; the nitrogen heated in the first heat exchange tube 414 is transported to the feeding box 421 through the first delivery tube 415;

[0075] Step 2: The fine materials crushed by the fan blades are delivered to the feed box 421 through the feed pipe 422, and the heated nitrogen in the first delivery pipe 415 blows the fine materials in the feed box 421 to the spiral feed pipe 424 between the combustion furnace 2 and the pyrolysis furnace 3, and the fine materials in the spiral feed pipe 424 between the combustion furnace 2 and the pyrolysis furnace 3 are preheated for a long time by the heated nitrogen; then the fine materials fall onto the cone panel 513 in the pyrolysis furnace 3;

[0076] Step 3: The motor 511 drives the cone panel 513 to rotate, and the fine materials on the cone panel 513 are dispersed to the surroundings under the action of centrifugal force. The fine materials fall from the cone panel 513 and move downward along the inner wall of the pyrolysis furnace 3 to accumulate until the fine materials move to the inner bottom of the pyrolysis furnace 3. The fine materials at the edge of the inner bottom of the pyrolysis furnace 3 pass through the lower side of the straight cylinder 523 and move to the bottom of the spiral blade 521 inside the straight cylinder 523;

[0077] Step 4: The rotating shaft 512 then drives the spiral blade 521, and the spiral blade 521 cooperates with the straight cylinder 523 to drive the fine material to lift upward until the fine material on the spiral blade 521 is separated from the top of the straight cylinder 523, and then the fine material is separated from the spiral blade 521 outward; thereby driving the fine material in the pyrolysis furnace 3 to circulate from top to bottom and from inside to outside;

[0078] Step 5: The nitrogen heated in the first heat exchange tube 414 is transported to the second heat exchange tube 532 through the second transport tube 531. The nitrogen in the second heat exchange tube 532 is heated again between the combustion furnace 2 and the pyrolysis furnace 3 and then transported to the annular tube 533. The heated nitrogen is transported to the multiple vertical tubes 534 through the annular tube 533 and then blown out through the air injection holes 535. The fine material in the pyrolysis furnace 3 is heated, and the pyrolysis mixed gas generated by the pyrolysis of the fine material is driven to be discharged through the pyrolysis gas pipe 31.

[0079] Step 6: After the pyrolysis is completed, the push cylinder 612 drives the slide plate 614 to move through the push plate 613, so that the slide plate 614 no longer blocks the discharge of the solid material after pyrolysis; the solid material after pyrolysis is discharged into the discharge bin 611 through the discharge port 32, and the push cylinder 612 pushes the solid material through the push plate 613; the electric push rod 624 drives the bin door 622 to lift through the mounting plate 623 to push out the solid material.
