[0036] Please refer to Figures 1-5 As shown, a pyrolysis oil heat recovery device, the pyrolysis oil heat recovery device includes:

[0037] A fixed bin 1, in the inner cavity of the fixed bin 1, a heat exchange coil 2 is fixedly arranged;

[0038] A spacer plate 6, the spacer plate 6 is fixedly arranged in the inner cavity of the fixed bin 1;

[0039] An automatic conduction component 7, the automatic conduction component 7 is fixedly arranged at the spacer plate 6, and the automatic conduction component 7 automatically conducts after the liquid level in the cavity drops.

[0040] Through the above technical solution, by arranging a plurality of spacer plates 6 in the fixed bin 1, the inner part of the fixed bin 1 is divided into several cavities. When heat exchange is carried out, the heat inside the cavities near the input end 201 can be concentrated, which is convenient for centralized recovery, so that the heat exchange liquid can be heated to a higher temperature, realizing the function of staged heat exchange. Further, in this application, an automatic conduction component 7 is designed. Through the automatic conduction component 7, when the liquid level in the cavity drops, the liquid in the subsequent cavity can be automatically transported to the previous cavity, realizing the function of automatic replenishment;

[0041] A plurality of the spacer plates 6 are provided, and a plurality of the spacer plates 6 are all fixedly arranged in the inner cavity of the fixed bin 1. A plurality of the spacer plates 6 divide the inner cavity of the fixed bin 1 into several cavities. Through this technical solution, the fixed bin 1 is divided into several cavities by the spacer plates 6, and a heat exchange liquid is injected into the inner cavity of the fixed bin 1 for heat recovery;

[0042] At one end of the heat exchange coil 2, an input end 201 is provided, and at the other end of the heat exchange coil 2, an output end 202 is provided. Through this technical solution, the high-temperature gas generated by pyrolysis oil processing is input through the input end 201 and output through the output end 202. The input end 201 flows in the inner cavity of the heat exchange coil 2 and exchanges heat with the low-temperature liquid to realize the cooling function. At the same time, the liquid in the inner cavity of the fixed bin 1 is heated to recover the heat;

[0043] A high-temperature liquid output end 4 is fixedly connected inside the cavity of the fixed bin 1. A control valve 5 is installed on the high-temperature liquid output end 4. The high-temperature liquid output end 4 is arranged inside the cavity near the input end 201. A cold liquid input end 3 is fixedly arranged inside the cavity of the fixed bin 1. The cold liquid input end 3 is arranged inside the cavity far from the input end 201. Through this technical solution, through the cold liquid input end 3, low-temperature liquid can be input into the cavity of the fixed bin 1, and the high-temperature liquid inside the cavity of the fixed bin 1 can be output through the high-temperature liquid output end 4. Since several inner cavities are provided in the fixed bin 1 in this application, and high-temperature gas is input through the input end 201, the liquid in the cavity near the input end 201 side heats up faster and has the highest temperature. As the high-temperature gas continuously flows and cools down, the liquid in the cavity near the output end 202 side heats up slower and has a lower temperature. And through the high-temperature liquid output end 4, the highest-temperature liquid can be output, so that the high-temperature liquid can be used in other processing steps, realizing the heat recovery work. At the same time, the recovered liquid has a higher temperature, and the high-temperature liquid is centrally recovered;

[0044] The automatic conduction assembly 7 includes a communication pipe 701, a control valve unit 702, a fixed footrest 703, a fixed cylinder 704, a counterweight slider 705, a floating cylinder 706, a guide roller 707 and a towing rope 708. The communication pipe 701 is fixedly arranged on the partition plate 6. The two ends of the communication pipe 701 are respectively communicated with the cavities on both sides. A control valve unit 702 is fixedly installed on the communication pipe 701;

[0045] The control valve unit 702 includes a valve body 7021, a closing core 7022, a fixed shell 7023, a limit slider 7024, a valve rod 7025 and a return spring 7026. The valve body 7021 is fixedly arranged on the communication pipe 701. A closing core 7022 is slidably connected inside the inner cavity of the valve body 7021;

[0046] A fixed shell 7023 is fixedly connected to the upper surface of the valve body 7021. A limit slider 7024 is slidably connected inside the inner cavity of the fixed shell 7023. The limit slider 7024 is fixedly connected to the top end of the closing core 7022. A valve rod 7025 is arranged on the upper wall of the fixed shell 7023. The bottom end of the valve rod 7025 extends to the upper surface of the limit slider 7024 and is fixedly connected to the limit slider 7024;

[0047] One end of a return spring 7026 is fixedly connected to the upper surface of the limit slider 7024, and the other end of the return spring 7026 is fixedly connected to the upper wall of the inner cavity of the fixed shell 7023. Through this technical solution, when the valve stem 7025 moves upward, it can drive the limit slider 7024 to move upward, thereby driving the closing core 7022 to move upward, making the valve body 7021 conduct, so that the connecting pipe 701 conducts, and the two chambers on both sides are connected;

[0048] The fixed support 703 is fixedly arranged on the side wall of the partition plate 6. A fixed cylinder 704 is fixedly connected to the bottom surface of the fixed support 703. A counterweight slider 705 is slidably connected in the inner cavity of the fixed cylinder 704. A floating cylinder 706 is fixedly connected to the bottom surface of the counterweight slider 705;

[0049] A guiding roller 707 is fixedly installed on the upper surface of the fixed support 703. One end of a towing rope 708 is fixedly connected to the upper surface of the counterweight slider 705. The other end of the towing rope 708 bypasses the guiding roller 707 and extends to the top of the valve stem 7025 and is fixedly connected to the valve stem 7025. Through this technical solution, when the liquid in the left chamber of the partition plate 6 is sufficient, the buoyancy of the liquid will push the floating cylinder 706 upward, so that the counterweight slider 705 moves upward, and then the towing rope 708 is in a slack state, so that the automatic conduction assembly 7 is in a closed state and the two chambers on both sides are not connected. When the liquid in the left chamber of the partition plate 6 is output and the liquid level drops, the floating cylinder 706 loses buoyancy, so that the counterweight slider 705 moves downward. The gravity generated by the counterweight slider 705 is transmitted to the valve stem 7025 through the towing rope 708, thereby driving the valve stem 7025 to move upward, making the closing core 7022 move upward, so that the control valve unit 702 opens, and the two inner cavities are connected, so that the liquid in the right chamber of the partition plate 6 is conveyed to the left chamber through the connecting pipe 701, realizing the function of automatic replenishment.

[0050] The circuits, electronic components and modules involved are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by this application does not involve the improvement of software and methods either.

[0051] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
