Description

Technical Field

[0001] The present invention relates to the technical field of heat pipe type biomass carbonization furnaces, and specifically relates to a heat pipe type biomass carbonization furnace with uniform heating. Background Art

[0002] With the continuous development of China's economic construction, the living standards of the people have been rapidly improved, and there has been a qualitative change in the utilization mode of daily energy in urban and rural areas. Using traditional crop straws, rice husks, firewood, etc. as daily fuels has gradually been replaced by coal, liquefied petroleum gas, etc. Therefore, it is particularly urgent to search for and develop a new energy and renewable resource.

[0003] In the prior art, there are technical solutions for carbonizing biomass raw materials by using a biomass carbonization furnace to produce biomass charcoal, such as pyrolyzing biomass raw materials through heated heat pipes to prepare biomass charcoal. However, when in use, the biomass raw materials are mostly conveyed along the same horizontal height of the heat pipes when being conveyed along the heat pipes by the conveying mechanism, resulting in the biomass raw materials always contacting the heat pipes at the same horizontal height. This not only fails to make full use of the heat on the heat pipes, but also reduces the efficiency of biomass carbonization. At the same time, the uniformity of the biomass raw materials on the conveying mechanism is poor, and some biomass raw materials will pile up on the conveying mechanism, causing the biomass raw materials to be unevenly heated. Moreover, it is difficult to ensure the overall temperature uniformity of the heat pipes after being heated, further affecting the uniformity of the heating of the biomass raw materials. For this reason, we propose a heat pipe type biomass carbonization furnace with uniform heating. Summary of the Invention

[0004] The purpose of the present invention is to provide a heat pipe type biomass carbonization furnace with uniform heating to solve the problems of not being able to make full use of the heat on the heat pipes, reducing the efficiency of biomass carbonization, and poor uniformity of the heating of biomass raw materials on the conveying mechanism as proposed in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A heat pipe type biomass carbonization furnace with uniform heating, including a furnace body. Two groups of parallel partitions are arranged inside the furnace body. The partitions divide the inside of the furnace body into a flow chamber, a carbonization chamber, and a combustion chamber from top to bottom in sequence. A heat pipe assembly is arranged inside the furnace body. The heat pipe assembly movably penetrates through the partitions. The heat pipe assembly is divided into three sections and is sequentially placed in the flow chamber, the carbonization chamber, and the combustion chamber. An inlet and an outlet are arranged on the carbonization chamber. A material conveying device is arranged inside the carbonization chamber. One end of the material conveying device corresponds to the inlet, and the other end corresponds to the outlet. Among them,

[0007] The heat pipe assembly includes several groups of heat pipe bodies. Several groups of the heat pipe bodies are arranged in multiple rows parallel to each other along the vertical direction of the furnace body;

[0008] The material conveying device includes several groups of material conveying parts and a material guiding part. The several groups of material conveying parts are distributed in a stepped and parallel manner in the carbonization chamber. The material conveying parts are placed between adjacent two rows of heat pipe bodies. The adjacent two groups of material conveying parts are connected end to end through the material guiding part to form an S-shaped conveyance to transport raw materials along the carbonization chamber.

[0009] Further improvement lies in that a cavity for connecting the flow chamber and the combustion chamber is provided in the heat pipe body. The outer wall of the heat pipe body is wrapped with a heat conduction layer. A plurality of groups of heat conduction fins are spirally distributed and inserted in the cavity of the heat pipe body. A groove is opened at the inner end of the lower surface of the heat conduction fin. One end of the heat pipe body obtains heat from the combustion chamber, and the high-temperature flue gas generated during combustion can enter the cavity of the heat pipe body. The heat conduction fins absorb heat to ensure the uniform heat reception of the heat pipe body. Moreover, the flue gas forms a "vortex" at the groove, extending the residence time of the flue gas in the heat pipe body, thereby extending the heat conduction time of the heat pipe body.

[0010] Further improvement lies in that the material conveying device further includes a vibration assembly. The vibration assembly includes a driving part and a linkage part. Both the driving part and the linkage part are arranged on the material conveying part. The driving part is used to drive the linkage part to drive the material conveying part to move upward. Through the vibration assembly, the material conveying part generates vibration, so that the biomass raw materials conveyed on the material conveying part are vibrated and evenly distributed on the material conveying part to ensure uniform heating of the biomass raw materials.

[0011] Further improvement lies in that the material conveying part includes a support frame and a chain grate. The chain grate is arranged in the support frame. Connecting frames are slidably arranged on both sides of the support frame. The top of the connecting frame is connected to the top partition plate. Elastic members for connecting to the support frame are arranged on the connecting frames. The elastic members are used to drive the upward support frame and the chain grate to reset downward. After the vibration assembly drives the support frame and the chain grate in the material conveying part to move upward, they reset downward under the action of the elastic members. Repeating this way makes the chain grate vibrate.

[0012] Further improvement lies in that the driving part is driven to work by one group of material conveying parts. The driving part includes a driving rod and a roller. The roller is arranged on the chain grate in one group of material conveying parts. The surface of the roller is in contact with the surface of the chain grate. The chain grate drives the roller to rotate. The driving rod is perpendicular to the chain grate and is arranged in the flow chamber. The roller drives the driving rod to rotate through a transmission member. When the chain grate conveys the biomass raw materials, it drives the roller to rotate under the action of friction. The roller transmits this rotational force to the driving rod through the transmission member to drive the linkage part to drive the material conveying part, without the need for a separate driving device.

[0013] Further improvement lies in that the linkage part includes a connecting seat and a cylinder. The connecting seat is arranged on the upper surface of the support frame. An L-shaped rod is provided on the upper surface of the connecting seat. The top end of the L-shaped rod penetrates through the top partition plate and extends into the flowing chamber. The cylinder is sleeved on the outer wall of the driving rod. A plurality of arc-shaped bumps are annularly arranged on the circumferential outer wall of the cylinder. The cylinder is driven to rotate by the driving rod and drives the L-shaped rod to move upward through the arc-shaped bumps. The rotation of the driving rod drives the cylinder, and the cylinder intermittently contacts the L-shaped rod through the arc-shaped bumps, so that the L-shaped rod intermittently drives the connecting seat upward, and the connecting seat drives the support frame and the chain grate upward, realizing the synchronous vibration of multiple feeding parts.

[0014] Further improvement lies in that the transmission part includes a telescopic connecting rod movably inserted on the top partition plate. The two ends of the telescopic connecting rod are respectively placed in the flowing chamber and the carbonization chamber. Hollow seats are movably sleeved at both ends of the telescopic connecting rod. A driving rod connected to a roller is movably inserted on the hollow seat in the carbonization chamber. One end of the driving rod is movably inserted on one side of the hollow seat in the flowing chamber. The hollow seat in the flowing chamber is fixedly arranged in the carbonization chamber. A bevel gear set is arranged in the hollow seat for transmitting and connecting the driving rod, the driving rod and the telescopic connecting rod. The rotation of the roller drives the driving rod, and the driving rod rotates to drive the telescopic connecting rod through the bevel gear set in one group of hollow seats. The telescopic connecting rod drives the driving rod to rotate through the bevel gear set in the other group of hollow seats, so as to drive the cylinder to rotate.

[0015] Further improvement lies in that a communicating return pipe is provided between the carbonization chamber and the combustion chamber. A one-way valve is arranged in the return pipe. The return pipe is used for the gas in the carbonization chamber to enter the combustion chamber. A smoke exhaust port is provided on the flowing chamber. Combustible by-products such as crude gas generated during the biomass carbonization process in the carbonization chamber can enter the combustion chamber through this return pipe to help the fuel in the combustion chamber burn fully, achieving the purpose of making full use of the by-products of the carbonization process and saving energy.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this application, the biomass raw material is conveyed along the carbonization chamber in an S shape through the chain grate in the material conveying part and the material guiding part from the feed inlet. When the biomass raw material is conveyed in an S shape, it corresponds to different heights of multiple rows of heat pipe assemblies, realizing the sufficient heating and carbonization of the biomass raw material and a continuous carbonization process. Moreover, the heat in the vertical space of the heat pipe assemblies can be fully utilized, improving the carbonization efficiency. The high-temperature flue gas generated in the combustion chamber can enter the cavity of the heat pipe body, and the heat is absorbed through the heat conducting fins, ensuring the uniform heating of the heat pipe body. And the flue gas forms a "vortex" at the groove, prolonging the residence time of the flue gas in the heat pipe body, thereby prolonging the heat conduction time of the heat pipe body, improving the uniform heating degree of the biomass raw material. At the same time, the vibration assembly makes the material conveying part vibrate, so that the biomass raw material conveyed on the material conveying part is shaken and evenly distributed on the material conveying part, further improving the uniform heating degree of the biomass raw material.

The telescopic connecting rod 73131 moves up and down with the chain grate 712 to telescope and change, ensuring that the roller 7312 is always in contact with the chain grate 712 while stably transmitting the rotational force.

[0034] Working principle: The biomass raw material is transported from the feed port 9 through the chain grate 712 in the material transfer part 71 and the material guide part 72 in an S shape along the carbonization chamber 4, and finally discharged from the discharge port 10. When the biomass raw material is transported in an S shape, it corresponds to the different heights of the multiple rows of heat pipe assemblies 6, so that the biomass raw material is fully heated and carbonized and the carbonization process is continuous. The high-temperature flue gas generated by the combustion chamber 5 can enter the cavity of the heat pipe body 61, absorb heat through the heat conductive sheet 63, ensure the uniformity of the heat of the heat pipe body 61, and the flue gas forms a "mediation" at the groove 64, prolonging the residence time of the flue gas in the heat pipe body 61, thereby prolonging the heat conduction time of the heat pipe body 61 and improving the uniformity of the heating of the biomass raw material. When the chain grate 712 is conveying biomass raw materials, the friction force drives the roller 7312 to rotate, and the roller 7312 drives the driving rod 7311 to rotate through the transmission member 7313, and the driving rod 7311 drives the column 7322, and the column 7322 intermittently contacts the L-shaped rod 7323 through the arc-shaped protrusion, so that the L-shaped rod 7323 intermittently drives the connecting seat 7321 upward, and the connecting seat 7321 drives the support frame 711 and the chain grate 712 upward. When the arc-shaped protrusion is staggered with the L-shaped rod 7323, under the action of the elastic member 714, the support frame 711 and the chain grate 712 are reset downward, so that the multiple material transfer parts 71 vibrate synchronously, and then the biomass raw materials on the chain grate 712 are vibrated and evenly distributed on the conveyor belt device to ensure that the biomass raw materials are evenly heated.
