Description

Technical Field

[0001] This utility model relates to the field of pyrolyzer technology, specifically to a waste heat recovery and conversion, and heating and air supply structure for a static pyrolyzer. Background Technology

[0002] The main function of a static lysator is to break down large structures or samples into smaller pieces for easier transport, processing, or subsequent analysis. Its principle is to use external force or energy to disrupt the internal bonds of the structure or sample, achieving lysis. The lysator utilizes high temperatures to rapidly decompose organic matter in the sample, generating small molecule compounds for subsequent qualitative and quantitative analysis. This method has wide applications in the field of organic matter analysis.

[0003] In existing methods of using pyrolyzers to pyrolyze materials, the waste heat from the airflow is difficult to recover and reuse, resulting in a large temperature difference between the inside and outside of the pyrolyzer and easy heat loss. Therefore, this method does not meet the current requirements. To address this, we propose a waste heat recovery and conversion, as well as a heating and air supply structure for a static pyrolyzer. Utility Model Content

[0004] The purpose of this utility model is to provide a waste heat recovery and conversion and heating and air supply structure for a static pyrolyzer, so as to solve the problem mentioned in the background art that when existing pyrolyzers are used to pyrolyze materials, the airflow containing waste heat is not easy to recover and reuse, resulting in a large temperature difference between the inside and outside of the pyrolyzer and easy heat loss.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste heat recovery and conversion and heating and air supply structure for a static pyrolyzer, including a support base, an air inlet mounting seat fixedly installed at the front end of the support base, a diverter seat fixedly installed on the inner side of the air inlet mounting seat, an air inlet pipe fixedly installed at the front end of the diverter seat, an inner wall installed on the rear end face of the air inlet mounting seat, and a heat insulation cover fixedly installed on the outer side of the inner wall.

[0006] A waste heat return pipe is installed between the inner wall and the heat insulation cover. The inner wall is composed of an outer circulation layer, a first spiral blade, and an inner circulation layer. The inner wall at the front end of the inner circulation layer is provided with multiple guide holes. The first spiral blade is disposed between the outer circulation layer and the inner circulation layer.

[0007] Preferably, a plurality of air guide pipes are fixedly installed on the rear end face of the diversion seat, a directional pipe is installed on the outer side of the air guide pipe, a second spiral blade is provided on the inner side of the air guide pipe and the directional pipe, and a partition plate is fixedly installed on the front end of the plurality of directional pipes.

[0008] Preferably, an air outlet pipe is fixedly installed in the middle of the upper surface of the heat insulation cover, a return chamber is provided between the air guide pipe and the directional pipe, a heat insulation chamber is provided between the outer circulation layer and the inner circulation layer, and the return chamber and the heat insulation chamber are connected through multiple guide holes.

[0009] Preferably, the rear end of the waste heat return pipe passes through the air inlet mounting base and is connected to the insulation chamber, and the bottom end of the air outlet pipe passes through the insulation cover and is connected to the insulation chamber.

[0010] Preferably, the second spiral blade is disposed inside the return chamber and fixedly connected to the air duct, the first spiral blade is disposed inside the insulation chamber and fixedly connected to the outer circulation layer, and the first and second spiral blades rotate in the same direction.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model uses a hot air furnace to input hot air into the inner side of the air inlet pipe and the distribution seat, and then distributes it into multiple air guide pipes. After being guided by the air guide pipes, the hot air is input into the inner side of the return chamber. The return chamber and the heat preservation chamber are connected through multiple guide holes, which can effectively extend the spiral conveying path and time of the hot air through the second spiral blade and the first spiral blade. The return chamber can achieve full and uniform heating of the pyrolyzer, ensuring the stability of material pyrolysis. The heat preservation chamber can insulate and isolate the pyrolyzer, avoiding the pyrolyzer from being affected by the internal and external temperature difference, which would cause the heat loss rate to be too large.

[0013] 2. In this invention, after the first spiral blades convey the airflow in a spiral manner, the airflow with reduced temperature is discharged through the air outlet pipe. At the same time, the airflow with residual heat in the hot air furnace is conveyed to the inside of the heat preservation chamber through the waste heat return pipe, which facilitates the continuous replenishment of heat inside the heat preservation chamber. This ensures the stability of pyrolysis while utilizing the waste heat. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figure 1 and Figure 2 This utility model provides an embodiment of a waste heat recovery and conversion and heating and air supply structure for a static pyrolysis unit, including a support base 1. An air inlet mounting seat 3 is fixedly installed at the front end of the support base 1. A diverter seat 12 is fixedly installed on the inner side of the air inlet mounting seat 3. An air inlet pipe 5 is fixedly installed at the front end of the diverter seat 12. An inner wall is installed on the rear end face of the air inlet mounting seat 3. The inner wall is composed of a circulating outer layer 7, a first spiral blade 8, and a circulating inner layer 9. The inner wall at the front end of the circulating inner layer 9 is provided with multiple guide holes 11. The first spiral blade 8 is disposed between the circulating outer layer 7 and the circulating inner layer 9. The heated airflow can be spirally transported again through the inner wall, thereby keeping the whole unit warm.

A directional pipe 14 is installed on the outside of the air guide pipe 13. Second spiral blades 15 are provided on the inner side of the air guide pipe 13 and the directional pipe 14. A partition plate 10 is fixedly installed at the front end of the multiple directional pipes 14. The input hot airflow can be spirally transported through the second spiral blades 15, thereby improving the contact path between the airflow and the air guide pipe 13 and the directional pipe 14.

[0022] A return chamber 16 is provided between the air guide duct 13 and the reversing duct 14, and a heat preservation chamber 17 is provided between the outer circulation layer 7 and the inner circulation layer 9. The return chamber 16 and the heat preservation chamber 17 are connected through multiple guide holes 11. The second spiral blade 15 is located inside the return chamber 16 and is fixedly connected to the air guide duct 13. The first spiral blade 8 is located inside the heat preservation chamber 17 and is fixedly connected to the outer circulation layer 7. The first spiral blade 8 and the second spiral blade 15 rotate in the same direction. The spiral conveying path and time of the hot air can be effectively extended through the second spiral blade 15 and the first spiral blade 8, which facilitates the full heating and continuous heat preservation of the inner wall, and realizes the stable pyrolysis of the material.

[0023] Please see Figure 3 and Figure 4 An insulation cover 2 is fixedly installed on the outer side of the inner wall. An air outlet pipe 4 is fixedly installed in the middle of the upper surface of the insulation cover 2. A waste heat return pipe 6 is installed between the inner wall and the insulation cover 2.

The bottom end of the air outlet pipe 4 passes through the insulation cover 2 and is connected to the insulation chamber 17. The insulation chamber 17 can keep the pyrolyzer warm, thereby reducing the rate of heat loss inside the pyrolyzer.

[0024] In use, the material to be pyrolyzed is fed into the inner side of the inner wall, the power is turned on, and the air inlet pipe 5 and the waste heat return pipe 6 are both connected to the hot air furnace. The hot air is fed into the inner side of the air inlet pipe 5 and the flow divider 12 through the hot air furnace and then distributed into multiple air guide pipes 13. After being guided by the air guide pipes 13, the hot air is fed into the inner side of the return chamber 16. The return chamber 16 and the heat preservation chamber 17 are connected through multiple flow guide holes 11. The inner side of the return chamber 16 is equipped with a second spiral blade 15, and the inner side of the heat preservation chamber 17 is equipped with a first spiral blade 8.

[0026] After the first spiral blade 8 conveys the airflow through the spiral blade, it is discharged through the air outlet pipe 4. At the same time, the airflow with residual heat in the hot air furnace is conveyed to the inside of the heat preservation chamber 17 through the waste heat return pipe 6, so as to facilitate the continuous replenishment of heat inside the heat preservation chamber 17, and ensure the stability of pyrolysis while realizing the utilization of waste heat.
